水球選手의 無酸素性 파워에 관한 硏究 = A Study on Anaerobic Power in Water-Polo Players

다국어 초록 (Multilingual Abstract)

The purpose of this study was to analyze the Anaerobic Power and Blood lactate concentration of Water-polo players (University and high school) in incremental load exercise. Subjects were selected from Korean National College of Physical Education and Seoul High School, whose careers had been 3 to 4 years in water-polo. The study utilized isokinetic muscle contraction test and Wingate test by Cybex-Ⅱ and computerized bicycle-ergometer.
The results of the study were as follows :
1. Anaeroble powers of water-polo players of the university and high school respectively were 57.62±3.99%, 48.8±8.74% in Extensor and were 45.5±7.30, 39.0±6.96% in Flexor by Cybex-Ⅱ.
2. Anaerobic powers between two groups by wingate test were 57.62±3.99KPM/S in College group, 50.58±3.17PM/S in High School group with a mean power and 68.49±6.19KPM/S in College group, 61.32±3.64KPM/S in High School group with maximal state. But It was a statistically significant differences (p <.001) between two group. Fatigue index of water-polo players of College and high school saparately were 31.14±2.36% and 37.96±4.56%. These data showed a statistically significant difference (p<.001).
3.Maximal blood lactate concentrations between College players and High School Players were 8.6±0.73mmoles/1 and 7.4±1.88 mmoles/1, revealing a statistically significant difference (p< .01) in 3 minute recovery. And recovery ratio respectively are 64.4%, 62.9% in not statistically significant difference at 10 minute of recovery.
4. Correlation coefficients between endurance ratio of extensor, flexor and maximal blood lactate respectively showed 0.872, 0.804 for water-polo player of univ. and high school. Between means, maximal values of wingate test and maximal blood lactate are 0.849, 0.860.
