TI  - The Relationship Between Isometric Strength and Sprint Acceleration in Sprinters.

AB  - PURPOSE: To examine the relationships between the isometric midthigh pull (IMTP), 
      isometric squat (ISqT), and sprint acceleration performance in track-and-field 
      sprinters and to determine whether there are differences between men and women. 
      METHODS: Fifteen male and 10 female sprinters performed 3 maximal-effort IMTPs, 
      ISqTs, and 3 x 30-m sprints from blocks. RESULTS: Among the men, the results 
      showed significant negative correlations between IMTP and ISqT peak force; 
      relative peak force; force at 100, 150, and 200 ms; rate of force development 
      (0-150 and 0-200 ms); and impulse (0-200 ms) and 0- to 5-m time (r = -.517 to 
      -.714; P < .05). IMTP impulse (B = -0.582, P = .023) and ISqT relative peak force 
      (B = -0.606, P = .017) significantly predicted 0- to 5-m time. Among the women, 
      no IMTP or ISqT variables significantly correlated with any sprint times. Men 
      measured significantly higher than women for all IMTP measures except relative 
      peak force. Men were significantly faster than women at all splits. When 
      comparing measures of the ISqT, there were no significant differences between men 
      and women. CONCLUSIONS: Variables measured during the IMTP and ISqT significantly 
      correlated with 0- to 5-m sprint performance in male athletes. Isometric strength 
      can have a sizable influence on 0- to 5-m time, but in some cases, the maximum 
      effect could be very small.
