To investigate the the body shape strength and kinematics that effects sprint expert performance 17 healthy male sprinters were measured using songxiam9000 high speed vidicon in the field ; body shape of sprint athlete were tested by steel rule ; meanwhile shoulder were tested at 60, 240and360 deg / sec velocities ; lower limb were tested at 60, 240 deg / sec velocitues using biodex - ii tesing and rehabilitation system in the laboratory this research provide theoretical basement to scientifically make reasonable exercise prescription and perfect sprint theory the result show that ( 1 ) the results of correlation indicate that 100m performance related to the shoulder fast flexion torque and hip flexion / extension torque ^ ankle fast dorsiflexion torque ; ( 2 ) the upper arm relaxing enclose and lower limbs length effect 100m performance ; ( 3 ) the biggest shoulder extension joint, swing rage of shoulder and the biggest elbow joint extension effect 100m performance
受試者為17名男子一、二級短跑運動員。使用松下m9000高速攝像機對100米跑動過程中的運動員進行錄像,同時測試短跑運動員100米成績,利用愛捷錄像分析系統獲取運動學參數;用人體測量尺測試短跑運動員的肢體圍度;同時採用biodex -型等動測力及康復統,測試運動員上肢肩關節及下肢
髖、膝、踝3個關節的等速
屈伸肌力。在角速度60 s (慢速) 、 240 s (中速)和360 s (快速)下測試肩關節等動向心收縮肌力;在角速度60 s9慢速)和240 s (快速)及120 s下測試下肢3關節等速向心及離心肌收縮肌力。
Yesterday, coach eddie jordan said the all - star forward would " probably " miss his seventh straight game with that strained left hip flexor
昨天,主教練埃迪喬丹說,全明星前鋒將「很有可能」由於左
髖屈肌的扭傷缺席最近的連續七場比賽。
Seated row : using exercise tubing, flex at the hips and shoulders ( not the spine ) to grasp the handles and sit upright on a bench or the floor with the elbows extended
坐式劃船:這項運動需要使用運動器械,屈曲你的髖和肩(而不是脊柱)以抓住手柄,保持直立的坐在臺子或地面上同時讓肘部保持伸展。
