Abstract: The article discusses research investigating the effects of a 4-week weight reduction period in male track and field jumpers and sprinters in either a high weight reduction group (HWR) or a low weight reduction (LWR) group on body composition, explosive power, and speed. Changes in fat-free mass (FFM), serum testosterone, and acid-base balance were also measured. The effect of a gradual weight reduction (GWR) diet with high protein and low carbohydrate on performance is discussed.
