Shoulder and hip roll changes during 200-m front crawl swimming.

  Purpose: To determine accurately the magnitude and changes in shoulder roll (SR) and hip roll (HR) throughout a 200m maximum front crawl swim and whether SR and HR were associated with swimming velocity (V). Bilateral roll asymmetries and timing differences between SR and HR were also investigated.
Methods: Ten male swimmers of national/international level performed a maximum 200m front crawl swim. Performance was recorded with four below and two above water synchronised cameras and four stroke cycles (SCs) were analysed (one for each 50m). SR and HR were calculated separately.
Results: Swimmers rolled their shoulders significantly more than their hips (p
