EFFECT OF RECREATIONAL SPORTS ON HANDGRIP STRENGTH AND ANTHROPOMETRY IN ADOLESCENT BASKETBALL AND VOLLEYBALL PLAYERS
Comparing hand anthropometry in adolescent basketball and volleyball players at a local college.
74 participants, 18-23 years recruited after informed consent. Purposive sampling used; 45 volleyball and 29 recreational, basketball players. Anthropometric measurements: Height, Weight, Body Mass Index, Dominant hand length, hand-span, upper extremity length and upper extremity bulk. Hand grip strength done by Biopac (SS2LB) on both hands.
Dominant hand length, basketball players=7.8 Â± 0.4â€³; volleyball players =7.6 Â± 0.4â€³; (statistical difference, p-value 0.016). Difference between the two groups for dominant hand span was insignificant. Dominant upper extremity bulk for basketball players > volleyball players (12.5 Â± 1.4â€³ and 11.9 Â± 0.9â€³, respectively).
Comparison between dominant and non-dominant hand grip strength within volleyball players, revealed significant p-value; mean hand grip strength for dominating hand > non-dominating hand. Same comparison was done for basketball players; no significant difference.
Categorical analysis showed non-dominating hand grip strength significantly different between volleyball and basketball players. No participant with strength < 15 kg was among basketball players but 5 (11.1%) among volleyball players. Similarly, 6 (20.7%) among basket-ballers had strength > 45 kg and only 3 (6.7%) among volleyball players. Similar difference observed for dominating upper extremity bulk.
Regression analysis showed non-dominating hand strength depends on hand length.
Difference between the players for dominating and non-dominating hand grip strength was insignificant.
Conclusion: Anthropometric data helps design specific sports training and justifies treatment and rehabilitation protocols in muscle physiology.
Key Words: Hand dimensions, hand grip strength, basketball, volleyball.
