Effects of different training intensities on oxygen intake were determined in this study. Sixteen male subjects aged 16-18 were randomly assigned to one of three training groups or a control group. The training groups trained 3 days per week on bicycle ergometers at different intensities (85 percent, 75 percent, or 65 percent of heart rate…

This study investigated the effects of 30 minutes of endurance jogging on pulse rates at rest, during exercise, and at recovery and eight skinfold fat measures in middle-aged women. Subjects were 15 middle-aged women between 30 and 58 years of age who had not been engaged in any exercise program at least for 1 year. Eight sedentary subjects were…

Illustrates how writing exercises involving epitaphs may be used to teach brevity, restraint, and lucidity. (DD)

Greater control of the muscular fatigue process is afforded by regulation of energy expenditure through monitoring the rate of contraction rather than by varying the duration of contraction. (Author)

Selection of proper competitive activities for athletes is discussed in relation to the acknowledged fact that cellular adaptation is dependent upon the specific program employed in training for competitive events. (MB)

While running up an incline at a speed chosen by themselves, subjects apparently will perceive the work effort to be the same as running on the level, when in fact it is costing them more energy. (MM)

Results suggest that severe muscular fatigue adversely affects total reflex time, especially the peripheral muscular component. (MM)

Exercises for children four to nine months old are presented with illustrations. (MS)

Comparison of the aerobic metabolic requirements of normal walking with and without 1-, 2-, and 3-pound handweights among nine adult males indicated that walking while moving handweights through large ranges of motion provides a combined upper and lower body aerobic stimulus that is sufficient for endurance training for persons with poor to…

This article reviews the history of research on exercise-induced asthma (EIA) and the pathophysiology of the condition, including its development and influencing factors. Four groups of drugs that are effective against EIA--theopyhlline, beta-adrenergic agents, cromolyn sodium, and anticholinergics--are discussed. (Author/CB)

To evaluate individual stretching programs of intercollegiate athletes, 238 athletes (164 male, 74 female) in ten sports were surveyed about their stretching practices. Almost all of the athletes stretched, but to varying degrees. Muscle groups stretched by the fewest athletes were the adductors, plantar flexors, hips, and neck. (Author/MT)

In order to assess if there existed a statistically significant increase in jumping performance when dropping from different heights, 32 males, aged 19 to 26, performed a series of maximal effort vertical jumps after dropping from eight heights onto a force plate. Results are analyzed. (Author/MT)
