Describes the procedure to test the hypothesis that subjects' brain waves in response to a television flicker (distraction) would be smaller in amplitude during television programs of high, in contrast to low, interest. Results from 12 viewers support the hypothesis. (CP)

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)

Nerve circuits are usually analyzed in terms of the axon, the long fiber of the nerve cell. It now appears that there are many circuits involving only the nerve cell's shorter extensions, the dendrites. (Author/BB)

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)

Lesgaft was the founder of the modern system of physical education in tsarist Russia. (MM)

It is suggested that measured by the internal clock of heartbeats or breathing, all mammals live a similar lifespan. This is based on the fact that mammals, regardless of size, breathe about 200 million times in their lifetime at a rate of 1 breath for every 4 heartbeats. (AJ)

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)

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)

Twelve postmenopausal women attending a 50 minute exercise class three times a week for eight weeks were compared with 10 controls who maintained sedentary routines. Results showed that the exercise group had higher serum alkaline phosphatase and lower serum calcium than the controls. (Author/CB)

Investigation of 16 men's choices and uses of stride lengths during motorized treadmill running found that stride length variations combined with treadmill grade affected maximal oxygen uptake. (Author/CB)

Resistance training causes a variety of physiological reactions, including changes in muscle size, connective tissue size, and bone mineral content. This article summarizes data from a variety of studies and research. (JL)
