The purpose of the study was to know the plyometric training effect on sand surface. Physical improvements have important implications on team sports, as players perform numerous explosive movements like kicking, tackling, jumping, turning, sprinting, and changing pace and directions during the match (Chaouachi et al., 2009; Duncan et al., 2006; Gabbett, 2000; Ostojic et al., 2006; Stolen et al., 2005), thus, plyometric drills usually involve stopping, starting and changing directions in an explosive manner (Gabbett, 2000). Plyometrics are training methods used by sportspersons in all types of sports to improve strength and explosiveness. Plyometrics exercises consists of a rapid stretching of a muscle (eccentric action) proximately followed by a concentric or shortening action of the same muscle and connective tissue. The stored elastic energy within the muscle is used to produce more force that can be provided by a concentric action alone. Researchers have shown that plyometric training, when used with a periodized strength-training program, can contribute to increases in vertical jump performance, acceleration, leg strength, muscular power, increased joint awareness, and overall proprioception (Miller, et. al., 2006). Fifteen volunteered high school students (N=15) were selected randomly and purposive sample was taken. Subjects underwent 12 weeks progressive plyometric training on sand surface. Pre and post-test were obtained for fourteen variables. Paired sample correlations and paired 't' test was computed to interpret the treatment effect. Results revealed that twelve weeks plyometric training differed significantly in all the fourteen variables of the study. It is concluded that plyometric training on sand surface can help in improving one's physical fitness components.
