TI  - Isometric Mid-Thigh Pull Correlates With Strength, Sprint, and Agility 
      Performance in Collegiate Rugby Union Players.
PG  - 3051-3056
AB  - Wang, R, Hoffman, JR, Tanigawa, S, Miramonti, AA, La Monica, MB, Beyer, KS, 
      Church, DD, Fukuda, DH, and Stout, JR. Isometric mid-thigh pull correlates with 
      strength, sprint, and agility performance in collegiate rugby union players. J 
      Strength Cond Res 30(11): 3051-3056, 2016-The purpose of this investigation was 
      to examine the relationships between isometric mid-thigh pull (IMTP) force and 
      strength, sprint, and agility performance in collegiate rugby union players. 
      Fifteen members of a champion-level university's club rugby union team (mean +/- 
      SD: 20.67 +/- 1.23 years, 1.78 +/- 0.06 m, and 86.51 +/- 14.18 kg) participated in this 
      investigation. One repetition maximum (1RM) squat, IMTP, speed (40 m sprint), and 
      agility (proagility test and T-test) were performed during 3 separate testing 
      sessions. Rate of force development (RFD) and force output at 30, 50, 90, 100, 
      150, 200, and 250 milliseconds of IMTP, as well as the peak value were 
      determined. Pearson product-moment correlation analysis was used to examine the 
      relationships between these measures. Performance in the 1RM squat was 
      significantly correlated to the RFD between 90 and 250 milliseconds from the 
      start of contraction (r's ranging from 0.595 to 0.748), and peak force (r = 
      0.866, p </= 0.05). One repetition maximum squat was also correlated to force 
      outputs between 90 and 250 milliseconds (r's ranging from 0.757 to 0.816, p </= 
      0.05). Sprint time over the first 5 m in the 40 m sprint was significantly (p </= 
      0.05) correlated with peak RFD (r = -0.539) and RFD between 30 and 50 
      milliseconds (r's = -0.570 and -0.527, respectively). Time for the proagility 
      test was correlated with peak RFD (r = -0.523, p </= 0.05) and RFD between 30 and 
      100 milliseconds (r's ranging from -0.518 to -0.528, p's < 0.05). Results of this 
      investigation indicate that IMTP variables are significantly associated with 
      strength, agility, and sprint performance. Future studies should examine IMTP as 
      a potential tool to monitor athletic performance during the daily training of 
      rugby union players.
