| Popis: | 104 The study was to understand the variety of forwarding indination, lowerlimb grounding angle and grounding time when triathletes run at differnent speeds. There were 12 excellent triathletes as the subjects, and test through counter-balance design by 6 different speeds on running machine and record by high speed camera. Angle measuring through angle analysis Screen-Protractor- Meazure to obtain the data which was analyzed by Repeated Measures and LSD used in the Post hoc Comparison, Pearson product-moment correlation, and regression equation. Results: 1.When runner speeds up, who forwarding indination increase, lowerlimb grounding angle increase, and grounding time decrease.2. There was moderate correlation among forwarding indination, lowerlimb grounding angle and grounding time at different speeds of running.3. The regression equation at different speeds and forwarding indination is y= 0.7676x + 9.0676，R²= 0.349, speeds up every 1 km/hr then forwarding indination increase 0.7676 degree. The regression equation of lowerlimb grounding angle is y= 0.6295x + 3.7601，R²=0.2564, speeds up every 1 km/hr then lowerlimb grounding angle increase 0.6295 degree. The regression equation of grounding time is -6.8595x + 304.22，R² = 0.4154, speeds up every 1 km/hr then grounding time decrease 6.8595 millisecond. Suggest that coach or political instructor to improve athletes’ strength of muscle and technical training of running, to maintain running angle and skill, thus to save their physical strength while running. |
