Effects of different stretching techniques on isokinetic strength and muscle oxygenation
碩士 === 國立臺灣師範大學 === 體育學系 === 100 === Purpose: To investigate the acute effects of the different stretching techniques on the isokinetic strength and muscle oxygen saturation. Methods: Eighteen male collegiate athletes (age, 21.4 ± 2.0 yrs; height, 179.8 ± 7.8 cm; weight, 73.8 ± 9.3 kg) voluntarily p...

Methods: Eighteen male collegiate athletes (age, 21.4 ± 2.0 yrs; height, 179.8 ± 7.8 cm; weight, 73.8 ± 9.3 kg) voluntarily participated in this repeated measures and counter-balanced designed study. All subjects were asked to perform three treatments separated by 48 hours, including control (CON), passive static stretching (SS, 3 × 30-sec), and passive ballistic stretching (BS, 3 × 60-sec), before the isokinetic strength test. The muscle oxygen saturation was measured by the near-infrared spectroscopy during treatments. After the treatments, the isokinetic strength (60°•sec-1、240°•sec-1) test, 2 sets of 3 repetitions with 2 min rest interval, was used to assess the peak torque, average peak torque, total work, and average power. Results: The peak torque in 60°•sec-1 at 2nd set (BS vs. CON, 3.09 ± 0.36 vs. 2.93 ± 0.28 N•m•kg-1, p < .05) and average value of two sets (BS vs. CON, 3.02 ± 0.35 vs. 2.88 ± 0.29 N•m•kg-1, p < .05) in BS treatment was significantly higher than those in CON. The average peak torque in 60°•sec-1 at 2nd set in BS was significantly higher than that in CON. The average peak torque at average value of two sets in 60°•sec-1 in BS was significantly higher than those in SS and CON (BS vs. SS vs. CON, 2.86 ± 0.34 vs. 2.74 ± 0.34 vs. 2.71 ± 0.28 N•m•kg-1, p < .05). No significant differences were found on peak torque, average peak torque, and total work in 240°•sec-1 among three treatments. The tissue saturation index during first set of stretching exercise in SS was significantly lower than that in CON (SS vs. CON, -5.73 ± 6.39 vs. -0.30 ± 4.82 %, p < .05). The average values of total haemoglobin during treatments in SS were significantly different from those in BS and CON (SS vs. BS vs. CON, -8.60 ± 1.47 vs. -5.14 ± 1.44 vs. 0.36 ± 1.41 μmol, p < .05). Conclusion: These results indicate that although the SS (3 × 30-sec) might not inhibit subsequent isokinetic strength, stretching in this manner might induce muscle deoxygenation. In addition, the pre-event BS might improve the isokinetic strength in low velocity (60°•sec-1), and attenuate the SS induced muscle deoxygenation. Cheng, Ching-Feng 鄭景峰 2011 學位論文 ; thesis 50 zh-TW |
