CONTEXT Neuromuscular adaptations following exercise training are believed to enhance sports performance. While abundant research is available on adaptations of the lower body to plyometric training, little is known about adaptations of the upper body to plyometric training. OBJECTIVE To examine the effect of plyometric training on neuromuscular adaptations in cricket players of different age groups. DESIGN Randomized parallel group active-controlled. SETTING Research laboratory, School Cricket ground, Sports Complex field. PARTICIPANTS Fifty-nine cricket players were randomly assigned to either the experimental group or the control group. INTERVENTIONS The experimental group was subjected to eight weeks of medicine ball plyometric training held thrice per week. Neuromuscular adaptations were analyzed pre- and post-training in three age groups: <18 years, 18-25 years, and >25 years. Analysis of variance was used to ascertain the training effects between and within the six sub-groups, that is, age group <18 years (control andexperimental), age group 18-25 years (control and experimental), and age group >25 years (control and experimental). MAIN OUTCOME MEASURES Muscle activation, upper body balance, upper body power and muscle strength. RESULTS Out of 59, 55 participants completed the study. Subjects aged <18 (adolescents) showed significantly greater improvements than those from the groups 18-25 and >25 (adults) on upper body balance and upper body power. Significant improvements were observed in the experimental subjects of all age groups on their muscle activity of biceps brachii, upper body balance, and upper body power following medicine ball plyometric training. CONCLUSIONS Though adolescent subjects were found to be more adaptive than adult subjects, experimental subjects showed significantly greater neuromuscular adaptations to medicine ball plyometric training than controls. These findings emphasize the need for coaches and athletic trainers to inculcate medicine ball plyometric exercises in training regimes of cricket players so as to improve their upper body performance.
