Data from two separate experiments conducted to ascertain the optimum protocol for a maximum anaerobic work output test on the bicycle ergometer indicated that the test duration needs to be approximately forty seconds and the optimal frictional resistance five to six kilograms. (MB)

Comparison of steroid-free male and female bodybuilders with sedentary controls and runners revealed that the bodybuilders had lower percentages of body fat. One-third of the female bodybuilders reported menstrual abnormalities. Lipid values of bodybuilders were comparable to a group of lean, aerobically trained athletes. (Author/CB)

Under the careful supervision of a trained fitness professional, the benefits of prepubescent strength training (improved strength, power, muscular endurance, bone density) outweigh the risks (acute and chronic musculoskeletal injuries). (CB)

A study of effects of squatting exercise on heart rate and blood lactate levels in trained and untrained males indicated that trained subjects performed more work and had higher heart rates and lactate levels at exhaustion untrained subjects, though heart rate and lactate levels were lower for trained subjects at a given bar mass or submaximal…

A study of 11 obese adults who exercised with hand weights concludes that using the weights increases the energy demands of walking but only slightly. Research and results are presented and analyzed. (JL)

The effects of stretching techniques on arterial blood pressure (ABP) were studied in three groups of 20 men each.
