Reviews the literature on the left ventricular structural adaptations induced by resistance/strength exercise, focusing on human work, particularly well-trained strength athletes engaged in regular, moderate- to high-intensity resistance training (RT). The article discusses both genders and examines the use of anabolic-androgenic steroids in…

The size of the exercising muscle is critical in the determination of the maximal physiological response to exercise. (MM)

Rope jumping is a good, all-around, physical exercise, promoting cardiovascular endurance, flexibility, muscular strength, and muscular endurance. (MJB)

The effects of exercise in children can be assessed by physiological measures of the respiratory and cardiovascular body functions and by anthropometric measures of body composition and maturation. Several methods and techniques in these areas are available to the researcher and practitioner for attempting to assess the physiological aspect of…

This study of high sustained heart rates observed during circuit weight training involving high resistance and low repetitions indicates that such training has no concurrent cardiovascular training effect. (MB)

Fitness programs now and in the future must offer built-in cardiovascular conditioning, variety, novelty, and change to meet the physical, mental, and emotional needs of our society. Aerobic dancing (dancing designed to train and strengthen the heart, lungs, and vascular system) is one of the first indoor group Aerobic exercise programs designed…

Effects of cardiac output and lactate accumulation in exercised muscles was studied. (MM)

This study proposed to determine the effects of aerobics on physical work capacity, cardiovascular function and body composition of 28 women aged 25 to 44 years. Measurements taken after a conditioning program showed significant changes in work capacity and cardiovascular function for the conditioned group but no change in body composition.…

Current knowledge in the area of muscle physiology is a basis for a discussion on strength training programs. It is now recognized that the expression of strength is related to, but not dependent upon, the size of the muscle and is probably more related to the ability to recruit more muscle fibers in the contraction, or to better synchronize their…

This review of the literature discusses and examines the methods used in physiological assessment of rowers, results of such assessments, and future directions emanating from research in the physiology of rowing. The first section discusses the energy demands of rowing, including the contribution of the energy system, anaerobic metabolism, and the…

Thirty-one championship caliber women athletes participating on varsity teams at Ohio State University were trained using two different conditioning programs, in an attempt to determine the physiological outcomes of weight training versus cardiovascular-oriented conditioning. Fourteen tennis players followed a program of high-resistance weight…

A program of cardiovascular endurance activities for children in grades four through six was developed to emphasize success and improvement and establish lifelong patterns of concern for and enjoyment of activities that contribute to physical fitness and optimum health. The activities in the program require more teacher preparation than the…

This article reports results of a study to determine effects of a supplemental physical education program based on health-related fitness factors taught and monitored by classroom teachers. Subjects were 130 students, grades four-six. Findings indicate the treatment group showed improvements in cardiorespiratory endurance, abdominal strength, and…

A study compared physiologic responses of healthy paraplegic males to those of healthy, able-bodied males during maximal arm ergometry. Fifteen able-bodied, healthy adult males and 13 healthy adult male paraplegics followed an exercise program involving heart rate, increased exercise loads, and oxygen uptake. Results from an analysis of the data…
