news:YNUbd.702$n81.283@trnddc08... Having purchased a very nice new home on a 'corner lot' two years ago, I have come to the realization that unless (or until) I install a chain link fence topped with razor wire, sirens, and searchlights, that every punk kid under the age of 40 cuts through my yard, on a variety of 2, 3 and 4 wheel devices, both powered and unpowered, on a daily basis. There is a complete and utter lack of respect for other people's property in this backwards ass hick town I live in. Apparently enough, there are damn few people who "don't feel comfortable cutting through someone's yard". I wish I had dogs again. ... 120+ pounds of mean-ass snarling dog tends to instill respect in the otherwise lawless populace. Mebbe it's time to get some new doggies. I think that's a fine idea. Free advice: you would probably be happier if you didn't live on a corner lot.. |

i think most of us who are very active find that all this exercise
stuff helps us maintain our weight but without a cut in calories not much weight loss.i think we all tend to just eat more the more active we are.i think we can eat more and not gain weight but the jury is still out on the weight loss part..again this is without some sort of calorie restriction in your exercise plan. |

This isn't exactly true. You can lose weight by diet, or exercise, alone, if the conditions are correct. Keeping the weight off is another issue. Americans (I can't speak for the rest of the world) tend to eat considerably more calories than they need. A couple of hours of exercise (for most of us) results in 2 hours where no high-caloric foods are consumed (locking some folks into a room might have the same effect). The actual number of Kcalories burned in exercise is surprisingly low because the biomechanical system is way too efficient. Moderate exercise reduces caloric intake according to a number of physiological studies. However, caloric intake increases in an individual if exercise exceeds some threshold (this depends upon individual metabolism, muscle mass, etc.), but generally, not to the point where weight gain is a factor. Halting exercise, however, does result in weight gain in these individuals if they do not reduce caloric intake as a result (the body still needs to feed the muscle mass, even though the exercise isn't maintaining those muscles). So, cycling, which can be done for several hours at a time, will, in most, produce significanly more weight loss than running simply because most of us can sustain the exercise for a longer period of time. Cycling is also less damaging to the skeleton, though knee injuries, especially doing hill work, are not uncommon. Bone mass can be maintined, if that is a concern, with a moderate resistance training program done a few times a week. Those who continue to exercise lose less bone mass than those who don't. As for runners, or anyone, who stops their exercise program, loss of bone mass is a concern. The benefits of running in this area are that you will regain bone mass (or reduce loss) more quickly because the body needs a strong skeleton to perform the exercise and will seek to protect itself from damage. Weight training can reverse bone mass loss, however, and should be part of your program, even if you are cycling. Rick |

Maybe what's really needed is to get real estate developers
hooked on riding. Or persuade them that developments with human-powered transportation facilities would be more lucrative for them than the usual cul-de-sac hell. But I think that endeavour wouldn't even have a snowball's hope in a urinal; those developers want to keep it 'affordable' for the buyers while maximizing their own returns. They do that by avoiding facilities, not by putting them in. The SF Bay Area is finally grasping the fact that the $$$'s don't exist for all the road infrastructure necessary for the typical housing developments, so a number of cities of buying into the concept of "Transit Villages", which higher density developments built around BART stations and similar locations. Such developments are inherently walking and cycling friendly. Chris Neary "Science, freedom, beauty, adventu what more could you ask of life?

The science of fat metabolism. why biking burns fat better than jogging. Fat burning occurs when you are at 65 percent heart rate. 85% is Fat burning peaks around 50-85% MRH (pretty big range, isn't it?). Above that range, you may find a range where you actually burn less fat as you go up in total calorie expenditure, but eventually the calorie expenditure will increase so high that even the inefficient fat burning uses more fat than your 50-85% peak. But you don't want to ride for an hour at those exertion levels. It's a mixture of aerobic and anaerobic (no course is perfectly flat) activity that slowly saps your carbo stores and your will to exercise just for fun and fitness. So yes. 50-65% MRH (or about 50% VO2max) is a very good and relaxing place to be if you are exercising to reduce your fat without the pain that high carbohydrate-burning activity can cause. And if it's comfortable, you may ride for an hour instead of half an hour, and that will certainly improve your calorie output. --Blair "If you aren't breathing hard you're going too slow; but if you can't carry on a conversation, you're going too fast." |

A couple of references: http://www.bicycling.com/qanda/0,3257,s1-89,00.html?category_id=363&article_type_id='qa' In that reference (an add for supplements) we see: # Are cyclists at risk for osteoporosis? # By Selene Yeager # Q. I've read that cyclists--even men--can be at risk for # osteoporosis. Is that true? Can taking calcium supplements help # prevent it? A. If the only time you move your body is when it's # clipped into a pair of SPDs, you could be raising your risk for this # bone-thinning disease. Cycling is a non-weight-bearing activity, # which means your bones don't have to support your own (or any # outside) weight to do it. That's good news for your joints, because # they're spared the stress, but it can be bad news for your bones # because they need stress to build. Without it, the body keeps # taking the calcium it needs from your skeleton without putting any # fresh bone back, and you lose bone density. What sort of riding does this writer do, apparently never climbing hills where pedal force is substantial and standing pedaling is anything but "a non-weight-bearing activity"? # The best thing for your bones--and the rest of your body--is to # throw in some cross-training. Weight training is particularly good # for building bones. Doing a full-body strength-training routine # three days a week strengthens your skeleton as well as your # muscles. Adding running into your routine a couple times a week (or # more in the off season) can strengthen bones as well. I take it this writer is not a bicyclist except around the block at home and not more than 10mph. But that doesn't matter because we've got to get to the pitch: # As for calcium supplements: They're great added protection. The # National Osteoporosis Foundation recommends getting 1,000-1,300 # milligrams of calcium a day. That's about three glasses of # calcium-fortified milk a day. If you don't eat much dairy, # definitely supplement. There's the punch line: "calcium supplements" # KEEP YOUR SKELETON STRONG # DON'T SMOKE: Human chimneys lose bone twice as quickly as # nonsmokers. (And, Einstein, sucking cigs doesn't help you ride.) # DITCH THE COLA: Carbonated drinks, especially colas, are high in # phosphorous, which blocks calcium absorption. Plus they're a big # zero in the nutritional category. Drink water, juice or tea # instead. # MODERATE BOOZE: Too much alcohol inhibits calcium absorption and # bone formation. Stick to no more than a drink or two a day. Well that make it all OK. These are unassailable "truths" so the supplements promo, by association, is also unassailable. # From November 2000 Bicycling magazine http://www.hhs.gov/news/press/2004pres/20041014.html This link has nothing to do with bicycling.
