Abstract
Background of the study: Plyometric training is commonly performed on firm surfaces (eg. grass and wood), but more recent study
has shown that drop jumps on sand induce less muscle damage when compared to a firm surface. However, jumping on sand causes
lower reuse of elastic energy and energy loss due to feet slipping during the concentric action. This might induce different training
effects compared to training on a firm surface. The lower impact on the musculoskeletal system induced by plyometric training on
sand might be useful during rehabilitation programmes.
Aims and objectives of the study:v The aim of the study is to find the effectiveness of plyometric training on sand versus grass on
muscle soreness and endurance among football player.
Methodology: Subjects were randomly divided into two groups, grass training group (n = 15) and sand training group (n = 15). After
the baseline measurements of endurance by using RAST test, plyometric training was given for 4-weeks, three sessions per week.
Muscle soreness was assessed at the end of each training session on a 7-point likert scale. Post-readings of muscle endurance and
muscle soreness were taken after the 4-week training programme.
Result: Data when compared after plyometric training revealed significant changes between two groups (p<0.0001), however players
in the sand group experienced less muscle soreness (p < 0.0001) than grass group.
Conclusion: The results of this study shows that while the plyometric training performed on sand surface reduces muscle soreness
and indicates a lowered fatigue index.
