A report is given on alterations in blood pressure, heart rate, left ventricular ejection time, and myocardial oxygen consumption during isometric contraction in a closed heated environment. (JD)

Subjects improved significantly in vertical jump capacity under both training regimes; however, no significant difference was found between the two training methods. (MJB)

In general, basketball players with moderately high aerobic power who reside at an altitude of 1,000 m do not display the hypoxic response to an altitude of 2,200 m expected of sea level residents and aerobically trained athletes. (JD)

A comparison is drawn between muscle use and timing in the skills of overarm throwing and of service in tennis. (JD)

The transition from aerobic to anaerobic metabolism is discussed. More research is needed on different kinds of athletes and athletic activities and how they may affect aerobic and anaerobic metabolisms. (CJ)

This study, designed to determine the effect of a prolonged running bout on the measurement of percent fat, produced erroneously low readings. It is suggested that previous exercise and state of hydration of subjects should be controlled prior to percent fat determination by hydrostatic weighing or scintillation counting. (MJB)

Active hip flexion is considered to be important for many physical activities. Six popular mobility exercises were compared in this study to see if active flexibility exercises would give superior results in improving daily or more permanent gain of active hip flexion. (Author/CJ)

A method for testing oxygen uptake while subjects are swimming is described and analyzed. (JD)

This study was made to determine torque-generating capabilities at two speeds in active young boys and girls for the knee and elbow flexors and extensors. (JD)

Results of an analysis of the Avery-Richardson Tennis Serve Test are presented. (JD)

Sources of error in body composition assessment by laboratory and field methods can be found in hydrostatic weighing, residual air volume, skinfolds, and circumferences. Statistical analysis can and should be used in the measurement of body composition. (CJ)

There is a degree of uniqueness in fatigue patterns, particularly between different levels of absolute maximum strength. Caution should be used when analyzing fatigue curves among subjects with unspecified strength levels. (CJ)

A multivariate post hoc procedure (the Roy-Bose procedure) which allows for the construction of an infinite number of confidence intervals or probability statements concerning the p variables, all of which hold at a 100(1-a) percent level of confidence, is demonstrated and compared to other procedures. (JD)

Defining and measuring professional obsolescence among physical educators is examined through a comparison of the current knowledge base of graduating physical education seniors and physical education practitioners. Results demonstrate a conflict between what experts think persons in the field of physical education should know and the actual…
