Lower limb maximal dynamic strength and agility determinants in elite basketball players

Abstract

Chaouachi, A, Brughelli, M, Chamari, K, Levin, GT, Ben Abdelkrim, N, Laurencelle, L, and Castagna, C. Lower limb maximal dynamic strength and agility determinants in elite basketball players. J Strength Cond Res 23(5): 1570-1577, 2009-The aims of this study were to examine the relationship between squat 1 repetition maximum (1RM) and basketball- relevant tests and the variables that influence agility (T-test) in elite male professional basketball players (n = 14, age 23.3 ± 2.7 years, height 195.6 ± 8.3 cm, body mass 94.2 ± 10.2 kg). T-test performance was significantly related to body mass (r = 0.58, p = 0.03) and to percentage of body fat (r = 0.80, p < 0.001). A significant negative correlation was observed between t-test and 5-jump test performance (r = -0.61, p = 0.02). Squat 1RM was significantly related to 5-, 10-, and 30-m sprint times. Stepwise correlation analysis showed percentage of body fat was the best single predictor factor (p < 0.05) of agility. Squat 1RM performance was the best single predictor of 5-m and 10-m sprint times (p < 0.05). In light of the present study's findings, agility should be regarded as a per se physiological ability for elite basketball players. Consequently, basketball-specific agility drills should be stressed in elite basketball training. Given the association between squat 1RM performance and short sprint times, squat exercises should be a major component of basketball conditioning. © 2009 National Strength and Conditioning Association.
