      Pull in Adolescent Dancers.

AB  - INTRODUCTION: The importance and potential benefits of muscular strength in the 
      adolescent's development for health and fitness has been demonstrated in the 
      literature. Maximal muscular strength and its assessment, however, is not a 
      primary assessment criterium in the selection of young talented dancers. METHODS: 
      The present study evaluated the within- and between session reliability, 
      variability, and minimal detectable change (MDC) of the isometric mid-thigh pull 
      (IMTP). Thirty-five participants (female n = 17) participated in 2 identical 
      assessments on the same day with 4-hour break in between. Three 3-second IMTP 
      were performed, and the mean peak force value was used for the analyses. RESULTS: 
      Within-session the ICC indicated excellent reliability (ICC = .99, 95% CI: 
      0.98-0.99). Between-session reliability was excellent (ICC = .98, 95% CI: 
      0.95-0.99). The standard error of measurement was 4% (48 N), the minimum 
      detectable change was 12% (134 N) and the CV was 3%. There were no within-session 
      statistically significant differences, but statistically significant differences 
      between-session were observed (P < .001). Limits of agreement ranged from -121 N 
      (95% CI -186 to -56 N) to 307 N (95% CI 243-372 N). CONCLUSION: The observed 
      results demonstrated excellent within- and between sessions reliability, low 
      variability, and an MDC of 12%. The consistency of the within-session scores 
      suggest that peak force data may be obtained with single try efforts. The 
      statistically significant difference in the means of the retest session, however, 
      suggests that the time of the day or the time since entrained awakening may be 
      affecting performance in adolescent dancers. The results of the current study 
      indicate that the IMTP is a reliable assessment tool for maximal muscular 
      strength in adolescent dancers.
