Understanding the biomechanical and physiological factors influencing force is important for designing and planning exercises. Knowing how the human body responds to various regimens of exercise is important for optimal design of exercise in which power, strength, and speed can be acquired in the shortest possible time with zero or lowest risk of injury…
Young (2006, p. 74) reported that exercises involving bilateral contractions of leg muscles for vertical movements, like squats and jump squats, are not effective in improving performance. In contrast, according to Young (2006, p. 74), plyometric training can lead to “significant increases in sprint acceleration performance, thus highlighting the importance of movement pattern and contraction velocity specificity.” Further, Harris et al. (2008, p. 691) reported that based on an experiment they conducted among thirty elite rugby athletes, the correlation between sprint ability and jumping ability is generally positive and of moderate to strong magnitude. Adopting the definitions reported by earlier works, Ploeg et al. (2010, p. 39) explained that plyometric exercises or plyometrics are exercises in phases that begins with intense eccentric muscular contractions followed by rapid concentric muscular contraction.
Drawing on various works, Ploeg et al. (2010, p. 39) explained that when muscle is stretched, the muscle stores elastic energy briefly and plyometric exercises use the stored energy to assist the concentric contraction to produce more force than what can be provided by a plain concentric action or a concentric contraction. ...
