| Summary: | 碩士 === 國立臺灣科技大學 === 醫學工程研究所 === 102 === Physiological adaptions are essential for distance running in which the performance is highly associated with minimizing metabolic energy expenditure and fatigue resistance. The purpose of this study was to investigate the effects of wearing ergonomic designed sport compressive garment (D-CG) and general compression garment (G-CG) on physiological response during and after exercise in recreational runners. Eight male recreational runners (aged 26.13 ± 2.36 years old and V ̇O2max of 48.88 ± 3 ml/min/kg) were recruited. All participates were assigned to wear G-CG, D-CG, and nearly nude (non-CG) to perform a 40 minutes 75% V ̇O2max treadmill run. The main effect between three CG conditions in running economy at the 40-minute of running (P =0.03). Significantly lower V ̇O2 (L/min) P <0.05 the time points after 20 of exercise were found between D-CG and N-CG (P <0.05). Compared to N-CG, wearing D-CG showed lower oxygen consumption at all the time points after 20 minutes running. Compared to N-CG, G-CG showed lower oxygen consumption at the time points of 25 and at the end of 40 minutes running course. However, there were no differences in cardio-respiratory response including cardiac output (Q ̇), stroke volume (SV) and Oxygen pulse (V ̇O2/HR). There was no difference in lactate and rating of perceived exertion among D-CG, G-CG, and N-CG prior to or post running trial. In recovery phase, there no significant difference in CK, Mb or VAS. These results suggest that wearing D-CG might enhance oxygen utilization and thus the performance in recreational runner after 20 minute submaximal running; however G-CG revealed no pronounce effect. Conclusion: This finding suggest that wearing D-CG is likely to enhance submaximal running after 20 minute running; besides, indicating that wearing D-CG were more consistent than wearing G-CG.
