This article discusses a study attempting to determine if a biotelemetry system developed for use on chickens could be suitable for monitoring electrocardiograms of humans during exercise. Techniques for its use are reviewed. (JS)

Fifty-six healthy nontrained women aged 18 to 48 were tested for maximal work capacity on a bicycle ergometer. The women were divided into three age groups. A continuous step-increment bicycle ergometer work test was administered with the workload starting at 150 kpm (kilometers per minute) and 50 pedal rpm (revolutions per minute). The workload…

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…

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)
