      Throughout a Block Periodized Training Cycle in Weightlifters.

AB  - The purpose of this study was to investigate the kinetic and morphological 
      adaptations that occur during distinct phases of a block periodized training 
      cycle in weightlifters. Athlete monitoring data from nine experienced collegiate 
      weightlifters was used. Isometric mid-thigh pull (IMTP) and ultrasonography (US) 
      results were compared to examine the effects of three specific phases of a 
      training cycle leading up to a competition. During the high volume 
      strength-endurance phase (SE) small depressions in rate of force development 
      (RFD) but statistically significant (p </= 0.05) increases in vastus lateralis 
      cross-sectional area (CSA), and body mass (BM) were observed. The lower volume 
      higher intensity strength-power phase (SP) caused RFD to rebound above 
      pre-training cycle values despite statistically significant reductions in CSA. 
      Small to moderate increases only in the earlier RFD time bands (<150 ms) occurred 
      during the peak/taper phase (PT) while CSA and BM were maintained. Changes in 
      IMTP RFD and CSA from US reflected the expected adaptations of block periodized 
      training phases. Changes in early (<100 ms) and late (>/=150 ms) RFD time bands may 
      not occur proportionally throughout different training phases. Small increases in 
      RFD and CSA can be expected in well-trained weightlifters throughout a single 
      block periodized training cycle.
