摘要:

In briefThis paper reports the findings of the effect of an eight-week starter fitness program on the first 1,362 people enrolled in it. The subjects were tested for cardiorespiratory fitness, body fat and weight,O2max, muscular strength and endurance, and flexibility, using the YMCA physical fitness test battery before the program started and after eight weeks of training. The classes met for one hour, three times a week. Both men and women reduced body weight, body fat, and resting heart rate, and increasedO2max, flexibility, and muscular strength and endurance. Improved fitness was related to compliance and whether the subject or his company paid for the program.

摘要:

In briefB15, a mixture of calcium gluconate and N, N-Dimethylglycine (DMG), is widely used by amateur and professional athletes because they believe it lowers blood lactic acid, stabilizes blood sugar during exercise, and reduces the effects of fatigue. In general, Russian studies report increased oxygen efficiency, but they are not properly controlled. Some American studies support the claims of reduced lactic acid and increased performance, but others show no measurable effects. The authors say further studies are needed, but it is illegal to sell B15as a dietary supplement or a drug.

摘要:

Nature changed the snow conditions and aged the ski population in Colorado, so resort owners retaliated with snow-making machines and more intermediate trails.
