| Abstract |
The purpose of this study was to investigate the physical activity characteristics and isokinetic muscular strength during kayak erogometer motions in elite kayak athletes. Participants consisted of 10 male kayak athletes and 10 male non-kayak athletes matched controls. Physical activity characteristics(PAC) was measured using tri-axial accelerometer during rowing motion using rowing ergometer. Isokinetic muscular strength was assessed the peak torque of elbow and knee joints. Independent t-test was used to analyze the data. As a result, Physical activity counts were significantly differences between kayak athletes and non-kayak athletes in sum of vertical(VT) and anteroposterior(AP) activity counts and sum of VT, AP and left-right activity counts(respectively, p<.01 and p<.01). There were significantly differences between the peak torque of kayak athletes and non-kayak athletes in internal-external rotation of elbow joints and left flexion of knee joint(respectively, p<.01 and p<.05). These findings suggest that PAC and isokinetic muscular strength needs to consider in the training of elite kayak athletes. Specially, it is important to improvement balance and flexibility of trunk and increase of brachialis muscle in the elite kayak athletes. But additional research is needed to confirm this finding. |
