Purpose : To examine correlations between peak force and impulse measures attained during the isometric midthigh pull (IMTP) and basketball-specific sprint and jump tests. Methods : Male, adolescent basketball players (N = 24) completed a battery of basketball-specific performance tests. Testing consisted of the IMTP (absolute and normalized peak force and impulse at 100 and 250 ms); 20-m sprint (time across 5, 10, and 20 m); countermovement jump (CMJ; absolute and normalized peak force and jump height); standing long jump (distance); and repeated lateral bound (distance). Correlation and regression analyses were conducted between IMTP measures and other attributes. Results : An almost perfect correlation was evident between absolute peak force attained during the IMTP and CMJ ( r = .94, R 2 = 56%, P &lt; .05). Moderate to very large correlations ( P &lt; .05) were observed between IMTP normalized peak force and 5-m sprint time ( r = −.44, R 2 = 19%), 10-m sprint time ( r = −.45, R 2 = 20%), absolute ( r = .57, R 2 = 33%), normalized ( r = .86, R 2 = 73%) CMJ peak force, and standing long-jump distance ( r = .51, R 2 = 26%). Moderate to very large correlations were evident between impulse measures during the IMTP and 5-m sprint time (100 ms, r = −.40, R 2 = 16%, P &gt; .05) and CMJ absolute peak force (100 ms, r = .73, R 2 = 54%; 250 ms, r = .68, R 2 = 47%; P &lt; .05). Conclusions : The IMTP may be used to assess maximal and rapid force expression important across a range of basketball-specific movements.
