Book Description
Isotonic and isometric exercises are two types of physical activities that have a significant impact on fitness and physiology. Isotonic exercises involve contracting muscles while moving a joint, such as doing bicep curls with weights or push-ups. Isometric exercises, on the other hand, involve contracting muscles without movement, such as holding a plank or doing wall sits. Both isotonic and isometric exercises can improve muscle strength, endurance, and tone. Isotonic exercises can also help improve cardiovascular health and promote weight loss, while isometric exercises can improve balance and posture. The impact of these exercises on physiology is also significant. Regular isotonic and isometric exercise can help lower blood pressure, reduce the risk of heart disease, and improve insulin sensitivity. Isotonic exercises can also help improve bone density and reduce the risk of osteoporosis. Incorporating both isotonic and isometric exercises into a fitness routine can lead to a well-rounded approach to physical activity that can help individuals achieve their fitness goals and improve overall health and wellness.

Book Description
First published in 1961, “[T]his book is the result of ten years of research and experiment in the problems of muscle strength and muscle training at the Max-Planck-Institut für Arbeitsphysiologie, Dortmund, Germany supplemented by further work at the Lankenau Hospital, Division of Research, Philadelphia, Pennsylvania. There is provided the present status of these problems, and there is demonstrated how muscle strength may be built and maintained with a minimum of time and effort. “The methods used are adaptable, with suitable modification, to children, to average young people, to athletes in training, to sedentary workers and older persons who wish to maintain bodily strength, and to those who have undergone surgery and need rehabilitation of the muscle structure—in short, to anyone who wishes to develop and maintain good muscle tone. “A strong and well-built body not only has pleasing appearance, it permits the undertaking of arduous physical activities or active sports without undue fatigue, and with real enjoyment. “It is the author’s hope that in this age of fast living and nervous tension, when there often seems neither time nor place for extensive exercise, this book will assist those who wish to maintain bodily strength and fitness—simply, at home, without elaborate equipment—on a do-it-yourself basis. It should prove of special benefit to teachers of physical education and rehabilitation.”—THEODOR HETTINGER, M.D.

Book Description
The purpose of the study was to investigate the effects of short bouts of maximal isotonic and isometric contractions on the development of strength and muscular endurance of the extensors of the knee. Subproblems investigated were crosstransfer, hypertrophy, and specificity of training. Sixty grade ten boys enrolled in a required physical education class at Bonnie Doon high school in the city of Edmonton served as subjects. After initially being measured for girth and fat, strength at angles of 115 degrees and 135 degrees of extension, and muscular endurance (holding time), the boys were randomly divided into three groups, each group containing twenty subjects. One group became the isotonic training group; a second group became the isometric training group; the third group became the control. The exercises were performed once daily, five days a week, for five weeks. The isometric exercise programme consisted of three six second maximal contractions. One contraction was made with the leg 90 degrees flexed, one at 135 degrees of extension, and one at 165 degrees of extension. The isotonic exercise programme consisted of lifting a maximal weight from the 90 degree flexed position to the 165 degrees extended position three times daily. Each bout required six seconds for the leg to be moved through the specified range. The leg was extended at a constant rate. Results were considered statistically significant at the .05 level of confidence. It was concluded that the isotonic exercise group increased significantly over the isometric group (F=6.26[subscript .05]), and both exercise groups increased significantly over the control group (F=26.95[subscript .01]), at the 135 degree angle, when measured for strength. Both exercise groups made a significant increase in strength over the control group (F=l8.91[subscript .01]) at the 115 degree angle. The muscular endurance, when measured by employing the same weight for both initial and final tests, increased significantly for the combined isotonic and isometric group scores of the trained leg (F=4.51[subscript .01]) when compared to the control. Cross-transfer of strength was statistically significant for both isotonic and isometric exercise groups at both the 115 degrees (.01 level) and 135 degrees (.01 level) angles. There was no evidence of cross-transfer of muscular endurance. No evidence was found to support either hypertrophy or specificity training.
