That works more than half the time against most dogs that consider chasing you just good sport. 2- Get away from their territory as fast as you can. 3- A water bottle squirt sometimes startles them. If they're waiting for you in the road and all you can see are teeth then you in a heap o' trouble. In those situations, I've turned around, slowly, not staring at the dog, and rode away. "Halt" works pretty well, and I've used it at times. It's range is about 8 feet. I bought a "DAZER", from Heathkit. Its a small ultrasonic sound generator that you point at the dog. My wife and I were tandeming on a back road and used it on a mildly aggressive German Shephard. It seemed to cause the dog to back off. By far, without a doubt, hands down winner, is a squirt bottle full of reagent grade ammonia, fresh out of the jug. The kind that fumes when you remove the cap. When I lived in Illinois I had a big, mean dog that put its cross-hairs on my leg whenever I went by. After talking to the owner (redneck), I bought a handlebar mount for a water bottle and loaded it with a lab squirt bottle of the above mentioned fluid. Just as the dog came alongside, I squirted him on his nose, eyes and mouth. The dog stopped dead in his tracks and started to roll around in the street. Although I continued to see that dog on my way to and from work, he never bothered me again. Finally, you can usually intimidate the most aggressive dog if there are more than one of you. Stopping, *and moving towards it will often cause it to back off*. ( But not always ). My bottom line is to always *run* routes that I'm not familiar with, with someone else. =========================================================================== Books and Magazines (Phil Cannon pcannon@spotlight.Corp.Sun.COM) Books ===== 1) The Lore of Running - Tim Noakes 2) The Complete Book of Running - Fixx 3) The Runner's Handbook - Bloom 4) Long Distance Runner's Guide to Training and Racing - Sperks/Bjorklund 5) The Runner's Handbook - Glover & Shepard 6) Beyond Jogging - Spino 7) Jogging, Aerobics and Diet - Royald 8) The New Aerobics - Cooper Magazines ========= Track and Field News (monthly $31 US per year) 2370 El Camino Real, suite 606 Mountain View CA 94040 415-948-8188 Fax: 1-415-948-9445 1-800-GET-TRAK (1-800-438-8725) The self-proclaimed "Bible of the Sport", T&FN is the source for major meet results in track & field, road racing, cross-country, and race walking from the high school to international levels.

"Satisfaction guaranteed" =========================================================================== Clothes (Winter/Summer) (Mike Gilson GILSON@ALF.CS.HH.AB.COM) Disclaimer ---------- Preference on the amount of clothing required for winter running varies widely between individuals. There are a couple of runners that I see that wear shorts, long sleeved T-shirt and gloves at 30F! So expect to experiment with how much clothing at various temp's. Second: I don't have any interest in the type of clothes you buy/wear; I neither make nor lose money by your choices. What I have to say here is *my* opinion only. Rules for Winter Running ------------------------ The first rule is to dress in layers. Outer layers can be added/shed easily. The second rule is to stay dry. When your clothes get wet, they get very heavy - heavy enough to degrade performance - and you get cold. The final rule is to hydrate. You may not sweat as much, but you still need to take in fluids. Clothing Layers --------------- Inner layer. The layer closest to the skin should be a tight, lightweight fabric that wicks water away from the skin. Shirts should be long-sleeved, skin-tight (without chafing), and may be turtle-necked (my preference). There are a variety of fabrics that are effective in wicking water; I have had a lot of success with polypro, but it is not machine washable. These are readily available at running specialty shops and mail order. For pants, lycra running tights work very well. Outer layer. The next layer should be a looser, mediumweight fabric that wicks water. A zipper at the neck is convenient for temperature control. I prefer a shirt that is slightly longer than waist-length so that I have the option of tucking it into the pants. I've had more success in finding these in cycling stores than anywhere else. Two layers of lycra tights work if it's really cold. Shell. A water-proof or water resistant shell that is breathable is useful in the coldest conditions. These are usually sold as suits, but tops are available separately at a higher cost (relatively speaking). Gore-tex is considered by many to be the best fabric, but there are cheaper alternatives. You can get these suits made to your measurements or buy them off the rack. I have a Burley jacket, which I purchased at a cycling shop. It's chief advantage over the running suits is the venting and extra zippers for temperature control. There are zippers under each arm, starting at mid chest going up to the armpit and travelling down the arm to about mid forearm. Tights. Tights have been mentioned above as inner/outer layers. Many people run in sweats, but sweats have two disadvantages: they're heavy and they get heavier when wet. Lycra is lightweight and warm, but costs more and shows off body (im)perfections more than sweats. Gloves. Any cotton glove works. Hat. A lot of heat is lost through the scalp, so a hat is a must for most people. Cotton hats get too heavy with sweat. Balaclavas are more versatile than hats, and allow you to cover you neck/face if requires. Both hats and balaclavas are available in wicking fabrics. Socks. A wicking sock will seem less heavy and your feet will be drier than a conventional sock. Coolmax socks are my preference, worn in a single layer. You can also find other fabrics, such as capilene or polypro socks, which are considerably more expensive. Running shoes. Runner's World (anyone know which issue?) had some tips from Alaskan runners on how to put (short) screws into the sole of the shoe for better traction on the ice. I haven't tried it, but you obviously have to be careful not to puncture the midsole, air/gel chambers, etc. Dressing for Winter Running --------------------------- Temp range Number of layers (degrees F) Inner Outer Shell Tights Gloves Hat Socks ------------------------------------------------------------------------- 50-55 1 0 0 1 1 0 0 40-45 1 1 0 1 1 0 1 30-35 1 1 0 1-2 1 1 1 20-25 1 1 1 2 1 1 1 0-15 1 1 1+pants 1 1 1 1 =========================================================================== Clothing materials (Jim Carson carson@mu.rice.edu) [Ed note: From a summary Jim posted] Polarlite Fluffy, fleecy stuff also called Polarplus and Synchilla. Comfortable. Incredibly warm, especially under something that breaks the wind. Doesn't wick moisture out very well. Breathes very well. Supplex (nylon) Comfortable. It is breathable and water repellent (but NOT water proof). Seems to absorb a small amount of water if it is really getting drenched Merino (wool) From a "breed of fine-wooled white sheep originating in Spain and producing a heavy fleece of exceptional quality." I guess you could treat this as normal 100% wool. Thermax An improvement on Polypro. The big advantage is heat resistance so you can put it in the dryer. Balance that against the extra cost. CoolMax This stuff seems more like a plastic bag than the revolutionary wicking material it is advertised as. Dacron Trademark name for Dupont polyester. Woven fabric made from dacron is similar to nylon ripstop or taffeta, but not as stretchy. Many of the better clothing insulations are made from dacron. They are usually refered to by more specific trademark names, like quallofil, hollofil, polarguard, and dacron-88. Lycra Used for its stretch, mostly a warm weather (>65 degrees) thing. GoreTex A teflon based membrane with microscopic holes. Gortex's claim to fame is that it will let water vapor (from perspiration) through, but not liquid water (rain). It blocks wind fairly well too. The membrane is delicate, so it always comes laminated between 2 layers of other material. It does not breathe enough. There are less expensive alternatives. Polypropylene Does not wick very well. Can be uncomfortable. Troublesome to care for (e.g. can pill badly) Will keep you fairly warm if soaked. Not very wind resistant. Melts in the dryer. Capilene Wicks moisture away. Very comfortable. Comes in different weights for more/less warmth. [lots of favorable things about it... only really unfavorable thing is the co$t] 60/40 cloth - This is a cloth with nylon threads running one direction, cotton in the other. It was the standard wind parka material before Goretex came along, and is considerably less expensive. Good wind resistance, fairly breathable. Somewhat water resistant, especially if you spray it with Scotchguard, but won't hold up to a heavy rain. =========================================================================== Cross-Training =========================================================================== General Information --------------------------------------------------------------------------- Running Mailing Lists 1) Dead Runners Society (Christopher Mark Conn sascmc@UNX.SAS.COM) The Dead Runners Society is a discussion group for people who like to talk about running. The group is very informal and social and we all try to encourage each other in our running programs. We talk about everything related to running, from meditation to marathons. We currently have about 300 members around the world.

(Jim Horalek) "Over" supination is the reverse - impact is shifted toward the outside of the heel. (Jim Horalek) Pronation and supination describe natural and normal motions of the foot during the walking or running stride. In a normal stride, the outside portion of the heal strikes the ground first. The foot pronates to absorbe shock. That is, it rolls inward. At the end of the stride, the foot re-supinates -- rolls outward-- on push-off. What the previous writer (Jim Horalek horalek@alliant.com) is defining is `over pronation', and `over supination'. These are excesses of the normal motions. Note that over pronation is fairly common and many shoes are designed to counteract this. Over supination is very rare. Most people who think they over supinate probably just under pronate. Some people who think they over pronate may in fact pronate a normal amount, but fail to re-supinate sufficiently at the end of the stride.

Sitaraman rks@phoenix.princeton.edu) (Thomas Page page@ficus.cs.ucla.edu) There seems to be a lot of debate and a few misconceptions about Fat burning, Stamina etc. Here are a few basics. They are based on standard scientific sources. 1. There are 3 sources of energy : Muscle glycogen, Liver Glycogen, Fat (triglycerides). There is also blood glycogen, which is what the brain runss off. 2. During excercise the glucose and fatty acid in the blood is utilised. Fatty acid in blood stream is utilised in preference to glucose for various reasons. (There are organs like the brain that can use only one energy source : glucose). Tom: Muscle glycogen is used before blood or liver glycogen. When you carbo load before a race, you are packing in the muscle glycogen. You only have a few minutes supply of blood glycogen once you start using that for running. 3. Then why can't we run on fat FOREVER ??? Because the fatty acid concentration in blood can never be much. In fact, it seldom exceeds (in Molars) the concentration of Glucose !!! Why this "transportation problem" for fats ?? There ain't much Albumin to transport the fat and fat in excess in blood stream will deposit on viens constrict and more directly cause blood clots and kill you !!! Tom: Noakes' book "Lore of Running" phrases it as "fat burns in a glycogen flame." Even a lean marathoner has a virtually unlimited supply of fat. But you are limited in your ability to mobilize the fat from the stores (fat deposits you know where), and you have the limited amount of glycogen needed to burn along with the fat. 4. As you workout aerobically, the fat acids start increasing in concentration in the blood stream. SO LONGER YOU WORK OUT THE GREATER PERCENTAGE OF WHAT YOU BURN IS FAT ! But remmeber that the fat concentration cannot go up too much. Only about 50 percent of your energy can come from fat. 5. So what happens if I run out of glucose ? Can I run on fat ? Very Very painfully perhaps. Your rate of glycogen usage is a complex function of your running efficiency, what percentage of VO2max you run (typically 85% for an all out marathon), what your VO2max is, how much glycogen you are able to store in your muscles, your state of fitness, etc. 6. Only long sustained exercise ( 30 -40 mins) is guaranteed to burn fat (see fat mobilisation etc above). Tom: During the first 10 minutes of exercise, you burn almost exclusively glycogen. From 10-30 minutes, you gradually increase the percentage of energy from fat, and hit a plateau between 30 and 40. So, keep running beyond 30-40 and you will keep burning a maximum amount of fat. The real magic of the 30-40 minute range is that if you stop running there, you will continue to burn a large percentage of fat, for several hours. 7. Some person said doing exercise with breaks as being better for burning fat. Not true. Neither does it build stamina. (Doing intervals to build stamina is fine. But it should not constitute more than small fraction of your total excercise duration. Most of it should be of the long continous endurance building type.) Tom: For the reason stated above, taking short breaks will not cause you to stop burning fat. If by taking walking breaks in the middle of your long runs you can keep going significantly longer, then taking walking breaks will increase the fat you burn. Also, if you are training for a marathon, you need to get in those 3+ hour runs. If you need a couple of walking breaks to keep going that long, you are better off taking them than quitting at 16 miles. Of course, if you can't run continuously for 3+ hours what you are concerned about is finishing the marathon, not racing it fast, so by all means take walking breaks. If you want to get fast, train until you don't have to walk. --------------------------------------------------------------------------- Conversion chart (Jack Berkery BERKERY@CRDGW2.crd.ge.com) 1 yard = .9144 meter 100 yards = 91.4400 meters 220 yards = 201.1680 meters 440 yards = 402.3360 meters 880 yards = 804.6720 meters 1 meter = 1.094 yards 100 meters = 109.400 yards 200 meters = 218.800 yards 400 meters = 437.600 yards 800 meters = 875.200 yards 1 mile = 1.609 Kilometers 1 mile = 1760 yards = 5280 feet 1 Kilometer = .6214 miles = 1094 yards = 3281 feet Kilmoeters to miles Miles to Kilometers ------------------------------------------------------ 1 km = .6214 miles 1 mile = 1.609 km 2 km = 1.2418 miles 2 miles = 3.218 km 3 km = 1.8642 miles 3 miles = 4.827 km 4 km = 2.4856 miles 4 miles = 6.436 km 5 km = 3.1070 miles 5 miles = 8.045 km 6 km = 3.7284 miles 6 miles = 9.654 km 7 km = 4.3498 miles 7 miles = 11.263 km 8 km = 4.9712 miles 8 miles = 12.872 km 9 km = 5.5926 miles 9 miles = 14.481 km 10 km = 6.2140 miles 10 miles = 16.090 km 11 km = 6.8354 miles 11 miles = 17.699 km 12 km = 7.4568 miles 12 miles = 19.308 km 13 km = 8.0782 miles 13 miles = 20.917 km 14 km = 8.6996 miles 14 miles = 22.526 km 15 km = 9.3210 miles 15 miles = 24.135 km 20 km = 12.4280 miles 20 miles = 32.180 km 25 km = 15.5350 miles 25 miles = 40.225 km 30 km = 18.6420 miles 1 marathon = 26 miles + 385 yards = 42.186 km --------------------------------------------------------------------------- Fluid replacement (2 personal methods) As an ultramarathoner, trail runner fluid replenishment etc. is quite important. My findings, based on personal experience, is that in 90+ degree weather I use a liter per hour on a one hour run - and that is carrying the water with me. If you are not running enough distance, dont be concerned about energy type drinks, and you probably don't lose enough salts to need electrolytes. But your system will absorb more fluid faster is it is hypotonic and cool. If you guys are always running for 45 minutes or an hour in HOT weather - I would really suggest carrying water. When you realize your dehydrated its TOO late - and it takes longer to replenish fluids than it does to lose them. (Milt Schol milts@mse.cse.ogi.edu) I prepare for a run with about 24-30 ounces of lukewarm water within 3 hours of the run. As for after the run, if it was particularly strenuous (and in the 85+ and humid Pittsburgh weather of late, the runs have been strenuous for me), within 10-15 minutes following the run, I take ~10-15 ounces of room-temperature, diluted Exceed (about 2 parts Exceed to 3 parts water). I follow that with about 24-30 ounces of room-temperature water over the next hour or two. (Barbara Zayas bjz@sei.cmu.edu) --------------------------------------------------------------------------- Noakes's Ten Laws of Running Injuries (John Schwebel jcs@cbnewsh.cb.att.com) Ten Laws of Running Injuries stated therein: The 1ST LAW OF RUNNING INJURIES: Running Injuries Are Not an Act of God The 2ND LAW OF RUNNING INJURIES: Each Running Injury Progresses Through Four Grades The 3RD LAW OF RUNNING INJURIES: Each Running Injury Indicates That the Athlete Has Reached the Breakdown Point The 4TH LAW OF RUNNING INJURIES: Virtually All Running Injuries Are Curable The 5TH LAW OF RUNNING INJURIES: X-Rays and Other Sophisticated Investigations Are Seldom Necessary to Diagnose Running Injuries The 6TH LAW OF RUNNING INJURIES: Treat the Cause, Not the Effect The 7TH LAW OF RUNNING INJURIES: Rest is Seldom the Most Appropriate Treatment The 8TH LAW OF RUNNING INJURIES: Never Accept as a Final Opinion the Advice of a Nonrunner The 9TH LAW OF RUNNING INJURIES: Avoid the Knife The 10TH LAW OF RUNNING INJURIES: There Is No Definitive Scientific Evidence That Running Causes Osteoarthritis in Runners Whose Knwees Were Normal When They Started Running --------------------------------------------------------------------------- Second Wind (Newsweek July 27, '92) If an Olympian experiences a second wind, it's probably a sign that he isn't in a great shape. Scientists are divided over whether a second wind is purely psychological - the athlete "willing" himself forward. But if it has a physical basis too, the sudden feeling of "I can do it!" right after "I want to die" probably reflects a change in metabolism. The body gets energy by breaking down glucose, which is stored in muscles. This reaction releases lactic acid, which the body must burn in order to prevent a lactic-acid buildup that causes cramps. Burning lactic acid requires oxygen. If the body does not breathe in enough oxygen; the runner experiences oxygen debt: the heart beats more quickly; the lungs gasp; the legs slow. The second wind, says physicist Peter Brancazio of Brooklyn College, may come when the body finally balances the amount of oxygen coming in with that needed to burn the lactic acid. (When burned, lactic acid is transformed into sweat and carbon dioxide.) Why doesn't everybody get a second wind? Couch potatoes don't push themselves past oxygen debt; true Olympians have enough lung capacity and cardiovascular fitness to avoid oxygen debt in the first place. --------------------------------------------------------------------------- Soda Pop (Paulette Leeper pleeper@wtcp.DaytonOH.NCR.COM) Q: Does anyone have any opinions on Soda pop as a drink in General. I find the CAFFEINE in soda to be irritating and DEHYDRATING, so, IMHO, drinking soda with caffeine (regardless of whether or not it contains sugar or aspartame) defeats the purpose of quenching thirst. It's much like drinking beer to quench thirst... it FEELS good, and TASTES good, but as a mechanism for hydration, it does the exact opposite. --------------------------------------------------------------------------- Computer Software (Jack Berkery berkery@emmax5crd.ge.com) (Paul Gronke, Gronke@acpub.duke.edu) There is a Shareware program in the WUSTL archives available through anonymous ftp.

Don't know how it functions under windows. ntu.ac.sg [155.69.1.5] AEROBIX.ZIP B 81246 910420 Fitness Log: Record aerobic exercise/progres JOGGR105.ZIP B 59053 920312 Runner's log and analysis database, v1.05 PT100.ARC B 175592 890914 Physical Training test scorekeeper database RUNLOG.ZIP B 71801 900308 Runner's/bicycler's workout log --------------------- All programs are available in the DATABASE directory on Simtel, via anonymous FTP. There are a number of Simtel mirrors, including WUARCHIVE.WUSTL.EDU (dir = mirrors/msdos/database), OAK.OAKLAND.EDU (dir = pub/msdos/database), and a lot of non US sites. RUNLOG.ZIP - I found this to be a barely usable program. It was not at all clear what I needed to enter at any of the prompts. There was no help key. There was no information telling me what format any times, distances, etc. need to be entered as. This does have a time prediction module. The interface is kind of nice. There are graphical displays of improvement, heart rate, etc. With a better manual expaining what you need to enter, I would rate is usable. At present, I found the other programs nicer. If you figure out what need to be entered where, you can use this program. JOGGR105.ZIP - This is a program of British origin. The interface is kind of interesting. It has most of the data entry options that you would want. It will graphically display your improvement. You can control the menu of courses so that you don't have to reenter distance and course info each time. Most annoying problem: everythin is in British units, so that you have to convert 100 meter dash, 5K, 10K, etc. into milage. This might not be a drawback for some; it is a major drawback for me. The data entry, printing is all nice. It escapes from errors well (unlike Runlog, which tends to bomb). This is definitely usable. RUNSTA11.ZIP - I really like this program and will continue to use it. It is by far the largest of the programs (300K zipped, 3 times the size of the others), so you might go for another if disk space is a problem. However, you get a full featured training / racing log for the space. What I like about it: 1) you can make it as complex or simple as possible. Via config options, you can enter for each race/training: shoes, weather, heart rate, health, hilliness, race surface, temp, calories...or none of these, depending on your preference. 2) You can easily set up a menu of courses to choose from in the race *and* training run entry 3) Race and Training are kept separate, a very nice feature if you want to track training runs and racing in the same database. 4) Multiple database files easily used, special configs are unique to each database file (meaning that you can monitor bicycle, running in the same program) 5) Can display data entries (runs) in a "calendar" format, then select the ones you wish to examine with a keystroke 6) Nice graphical displays Drawbacks: requires more memory than the other programs. Might not run on pre-286 machines, but I don't know. More disk space required. Not sure if it does time forecasting, i need to check. =========================================================================== Hashing From: Dweezil the Butt Beaker <daveo@theopolis.orl.mmc.COM> Subject: Rules of Hashing (one version, re: Rule Six) Organization: Orlando Hash House Harriers X-Hhh: A Drinking Club With A Running Problem. X-Hhh-Motto: If you have half a mind to hash, that's all you need. X-Hhh-Philosophy: Carpe Cerevisiam X-Oh3-Motto: We get drunk, we get naked, we give hashing a bad name. X-O2H3-Motto: We have beer, we have cookies, we give hashing a nice name. X-Dbh3-Motto: Daytona Beach Hash House Harriers never run out of beer. X-Dbh3-Motto: We have beer before, during, and after the hash. The Hash House Harriers is a running/drinking/social club which was started by bored expatriates in Kuala Lumpuer, Malaysia in 1938. ("Hash House" is the nickname of the restaurant/bar to which they retired for food and beer after a run.) Hashing is based on the English schoolboy game of "Hare and Hounds"; a Hash is a non-competitive cross-country run set by one or more runners called hares. The hares run out in advance of the other runners (the pack of hounds), and set a course marked by white flour, toilet paper, and/or chalk marks. Hash Rules ---------- 1. A HASHMARK is a splash of flour used to mark the trail. The pack should call out "On-On" when they see a hashmark. Blasts on horns, whistles, and other noise makers are encouraged. Hounds asking "RU?" (are you on trail?) of the FRB's (Front-Running Bastards) should be answered "On-On", which means they are on trail, or "Looking", which means they`ve lost the trail. 2. ARROWs, or several closely spaced hashmarks, are used to indicate change of trail direction. Hound should use arrows different from those used by the hares as necessary to assist hounds further back in the pack. 3. A CHECKMARK is a large circled X, or a circle with a dot at its center (fondly known as a "Titty Check"). Checkmarks indicate that the trail goes "SFP"; that is, the pack must search for true trail. Hounds should call out "Checking" when they see a checkmark. (Checking IS NOT Looking!) 4. A Backtrack is three lines chalked or drawn in flour across the trail, indicating a false trail. The pack, upon encountering a backtrack, calls out "On-Back" or "Backtrack", and goes back to the last checkmark to find true trail. Sometimes a hound will draw an arrow with a backtrack sign at the checkmark to identify the false trail for the rest of the pack. A CHECKBACK is a devious variation of the checkmark/backtrack. A checkback is a CB followed by a number. For example, a "CB 5" means to backtrack five hashmarks, then look for true trail as one would at a check. Also known as a COUNTBACK. A WHICHWAY is two arrows, only one of which points toward true trail; no hashmarks will be found in the other direction. 5. Tradition requires a DOWN-DOWN (chug-a-lug) of a beer after a hasher's virgin hash, naming hash, and other significant occasions, e.g., 25th hash, 50th hash, etc. A Down-Down is also in order for hares, visitors, and for any other reason that can be thought up. While frowned upon as "alcohol abuse", it is permissible for non- drinkers to pour the beer over their head; a soda Down-Down may also be elected. The primary consideration of the Down-Down is that once the mug leaves the drinker's lips, it is turned upside-down over the head. 6. THERE ARE NO RULES. =========================================================================== Interval training (micbrian@ubvmsb.cc.buffalo.edu) First off, keep in mind that the interval part of the run is the rest part. This is where your body recovers and strengthens itself. Secondly, say your goal is to run an 8 minute/mile 10k. Start your intervals by doing 5X400m at a little under 2 minutes per rep. You'll see that an 8min mile is a 2min 400, so to better that, you run a little faster, as I said. Walk or jog between the rep (this is the interval). Remember to keep with what you started at. If you jogged to rest, don't walk during the next interval. Intervals should be challenging, but not defeating. If you are having problems maintaining your form during the course of the whole run, you are doing too much. You should feel good at the end of your run, not ready to drop dead. Remember to warmup and cool down sufficiently before and after intervals. 10 minutes of jogging is suggested. Other things to remember: you can customize intervals to achieve different things. For example, to increase endurance, you can decrease your interval while running the same rep. Or you can increase the rep and still do the same interval. You can work on speed by running faster reps. There are other variations as well, but I don't remember all of them. Lastly, make sure you have a good aerobic base when you start, and don't do too much too fast. You can tire your muscles out, and it will take a while to recover. Your goal is to exercise your fast twitch muscles, those used for speed. I've been doing intervals for about 2 months now, and it has made a difference. The first race I ran after starting intervals, my time dropped by about 15 seconds. I have a race tomorrow, and am hoping to improve on that. I also notice I have more pep in my regular workouts. I get out there, and once I'm warmed up, my body wants to run fast. =========================================================================== Legs Sore knees (Elizabeth Doucette ead@tmsoft.uucp) When running (also walking, and cycling), the inner most quad. muscle (inner part of thigh) does not get exercised as much as the other three quad. muscles of the thigh. If this inner muscle isn't strengthened by specific exercises, an imbalance of the muscles may occur. This can cause irritation of the underside of the kneecap (chondromalacia patellae) because the imbalance of the muscles can pull the kneecap towards the outside of the leg. I believe there is a groove in the underside of the kneecap that rides on a ridge of bone in the knee. If the kneecap is pulled to the outside of the leg, the groove will want to move in a slightly different direction than the ridge of bone. This can cause the groove to become irritated. I had chondromalacia patellae for a long time (and many of my running friends did too) but I haven't had problems since I've been doing specific exercises for my inner quad. muscle. It is tedious and boring but it works. I haven't had knee problems for about 3 years now :-). I should do this every day, whether I work out or not, but I don't always. If I feel any discomfort at all in my knees, I make sure I'm more diligent with this exercise and the discomfort always disappears. I'm always able to prevent a problem now. The exercise is just a leg raise with the foot flexed and pointing away from the body. With this exercise make sure that your back is supported. As your quad. muscles fatigue, there is a tendency to help out with your back muscles. You may not realize that you're doing this until you notice later that your back is a little sore. Sitting on the floor, bend one leg (like you're going to do a sit-up), bringing the knee towards the chest. The other leg is straight. Place your hands behind you on the floor to support your back. You can vary this by leaning against a wall and hugging your knee to your chest with both arms. YOUR CANNOT BE TOO CAREFUL WITH YOUR BACK. For ease of explanation, start with your right leg being straight and flex your foot (bring your toes towards your head, as opposed to pointing them away from you). Turn your leg to the right, so that your toes and knee are pointing to the right as far as possible. The position of the foot is important because it helps to isolate the inner quad. muscle. Now, do leg raises. When I started I could only do 10 or 20 before I needed to rest. Don't do the leg raises too quickly because technique is more important than speed. I now do three sets, each leg of 60 repetitions (alternating legs after each set) for a total of 180 per leg. It takes me about 10 minutes. You can tell if your muscle is getting fatigued because it will start to quiver. Don't push it, change legs. Keep note of how many repetitions you do before you get fatigued and try to increase the repetitions next time. Compare you to you, not to others. Leg presses used to bother my knees. Now that I'm doing leg raises, the leg press doesn't bother me any more. Technique is important when doing leg presses. (Technique is probably more important than the fact that I'm doing leg raises). Make sure that the seat is forward far enough, so that when you press you cannot lock your knee. This makes the initial position feel too cramped. My knees feel too close to my chest. But it works for me and for others (both men and women) that I work out with. Nautilus equipment uses a cam system, such that there is less resistance on your knees in the initial, starting position, so there is less chance of injury. --------------------------------------------------------------------------- Leg Massage (John Boone boone@IDA.ORG) (From Bicycling magazine, pp.76-77, July 1992, Reproduced without permission) MASSAGE TECHNIQUES 1. Full Muscle Flush This surface stroke prepares the muscles for deeper work. It loosens the fibers and increases the blood flow to wash out lactic acid and other toxins. Begin with the calves. Place the palms flat against the bottom of the muscle and stroke toward the heart in a continuous movement. Always stroke toward the heart so the blood containing the toxins isn't traveling back into the muscles. After a few of these, knead the muscle during the stroke by working the bottom of the palms in and out. End with the original flat stroke. 2. Broad Cross-Fiber Stroke After each muscle group has been flushed, use the same palm position at the center of the muscles, but work sideways. Press harder than the flush. The hands are moving acros the muscle fibers, separating them and making them pliable so the massage can go deeper with the next type of stroke. This is a great supplement to stretching. It makes muscle fibers less likely to tear. End with more flushing. 3. Deep Muscle Spress "Spress" is a Swedish term. This technique is also known as muscle stripping. Use fingers, knuckles, or even elbows to penetrate the muscle. [Press deep into the leg where previously rubbing the surface.] Apply pressure until the comfort limit is passed. If there's pain, work slower, or do a few palm strokes before spressing again. Knuckles and thumbs work best. Concentrate on specific areas, instead of stroking the whole muscle. But remember to work toward the heart. SELF-MASSAGE Initial Strokes Self-massage uses the same sequence of strokes as assisted massage, and the same order of muscles -- calf, quads, hamstrings, glutes. But it's usually less effective because self-massagers get tired or bored quicker. The most common mistake is skipping the full-muscle flush or cross-fiber stroke to concentrate on the spress in the sorest areas. If you don't prepare the muscles, you won't be able to penetrate deep enough. [...] Be sure you're applying pressure with both hands. Sometimes one side of the leg gets shortchanged. Going Deeper The advantage of self-massage is that you know exactly where it hurts and can key on these areas. You also know when your muscles are loose enough for deeper penetration. [...] Amateurs usually don't go [deep enough] in assisted massage, or do so too quickly and it hurts. You can find that perfect balance. [...] It's best to use both [hands], but fatigue is a problem in self-massage. -- Yonson Serrano yserrano@us.oracle.com -. .-
