Abstract

Shot speed and accuracy are essential key elements in the game of lacrosse. Shot accuracy is a frequently practiced skill. However, less attention is often paid to developing shot speed. Training programs for lacrosse players may play a role for developing the muscular strength necessary to create high-speed shots. PURPOSE: To determine the effect of muscular strength on shot speed in male collegiate lacrosse players. METHODS: Twenty male club lacrosse players (age=20.35±1.09 yrs; ht.=182.15±6.09 cm; wt.=86.30±9.17 kg) performed a one repetition maximum (RM) power bench press, a one RM squat, and a timed bent knee sit-up test. Shot speed was determined using a speed gun aimed at a player from twelve yards away as they used an overhand technique to shoot a lacrosse ball into an empty lacrosse net. Two steps were allowed during shot wind up. Averages of five shot speeds per player were recorded and a Pearson Product Moment Correlation was used to determine relationship between muscular strength and shot speed. RESULTS: Shot speed (SS) when correlated to 1 RM bench press (BP) resulted in a moderate relationship (SS=85.00±4.69 mph; BP= 94.09±20.72 kg; r=0.519; P=0.019). Shot speed when correlated to 1 RM squat resulted in an extremely low relationship (SS=85.00±4.69 mph; squat=127.38±18.32 kg; r=0.136; P=0.566). Shot speed when correlated to number of bent knee sit-ups completed in one minute resulted in a negative moderate relationship (SS=85.00±4.69 mph; sit ups=49.90±3.81; r=-0.462; P=0.040). CONCLUSION: Upper extremity muscle strength has a statistically significant effect on the shot speed of college aged male lacrosse players.
