EFFECTS OF SIX WEEKS OF TRAINING ON INTERSEGMENTAL COORDINATION IN THE ROWING STROKE OF NOVICE INTERCOLLEGIATE ROWERS

The purpose of the study was to examine changes in coordination during the rowing stroke after 1 and 6 weeks of practice. Initially 11 healthy, females who had elected to join a college rowing program volunteered to participate in both testing sessions: Only 3 participants were still on the novice team at wk 6, thus N=3. Participants were video taped on a land ergometer in 2D using the Peak Motion Measurement System. SPC was assessed between adjacent 2-segment combinations of the T-S (trunk-shoulder), K-T (knee-trunk), and S-E (shoulder-elbow) to quantify intersegmental coordination. Mean changes in T-S (78.7% v 74.6 %), K-T (66.5% v 102.9%) and S-E (88.2% v 71.3%) showed that the rowing stroke is primarily a simultaneous pattern. However. individual SPC (shared positive contribution) changes varied indicating that 6 wks is not a long enough for coordination to develop in novice rowers

EFFECTS OF POST-ACTIVATION POTENTIATION ENHANCEMENT ON JUMP ASYMMETRY USING BANDED SQUATS WITH PROFESSIONAL AMERICAN FOOTBALL PLAYERS

Understanding the effects complex training has on symmetry could potentially supply practitioners with the knowledge to provide safe and effective training for their athletes. The purpose of this study was to determine the effects of post-activation potentiation enhancement (PAPE) using banded squats on symmetry during a countermovement jump (CMJ). Professional American football players (n=8) performed four trials of CMJs on dual force plates to record limb asymmetry and jump height with a set of heavy banded squats between each trial to ensure a potentiation effect was present. There were no significant changes in asymmetry across the 4 trials, p\u3e.05. However, jump height did significantly improve F(3,21) = 3.69, p=0.028. Banded squat training has no effect on jump symmetry
