Comparison of Hand Grip Strength in Different Wrist Positions in Right and Left Handed Tennis Players

Wrist position is one of the major factors that affect grip strength. In tennis, the quality and strength of stroke depends largely on racket grip. Compared to normal population, higher prevalence of left-handedness has been reported at elite level sports like cricket, baseball and tennis suggesting that left-handed athletes might have an advantage in these domains. Thus, this study was conducted to compare hand grip strength in different wrist positions in right and left handed tennis players. Hand grip strength of 40 Tennis players (20 right and 20 left handed) was measured using Jamar handheld dynamo-meter in different wrist positions. Prior to the test, age, height and weight were recorded. Hand grip force was 33.75±9.77 – 33.18± 5.79 kg (mean ± SD ), 23.80 ± 8.14 – 24.63 ±6.98 kg, 25.92± 7.78 – 28.41±5.53 kg, 23.77 ± 6.79 – 25.02 ±5.42 kg and 25.75 ± 11.48 – 25.21 ±4.93 kg at neutral, wrist flexion, wrist extension, ulnar deviation and radial deviation respectively. (p≤0.05) There was no significant difference in hand grip strength in different wrist positions between right and left handed tennis players.
