Mountain bike muscle endurance athletes torso flexion and extension characteristics research

Mountain bike muscle endurance athletes torso flexion and extension characteristics research
Mountain bike project is a concentration of power, speed, endurance, technology, the rhythm, which Cargo bike all the way, the people, the combination of car complicated mechanical movement project, require strong endurance. Although lower limb muscle is the main power source of cycling, but the core muscles shoulders on the responsibility of stable trunk, so that the arms and legs can complete brain conduction on the basis of the stability of instructions. Almost motionless while the upper part of the ride, but only to Three wheel bikes a stable core muscle group, to let the foot pedal power efficient role to the pedal as soon as possible. Mountain bike riding core muscle group in the process of main effect is to keep the body posture, maintain body balance, stability, upper limbs, fixed spine and pelvis, for lower limb muscle group [action power to provide a stable foundation. In a long ride, core muscle group basic with isometric contraction of static sex work is given priority to, energy consumption, easy fatigue, especially the small muscles. Numerous literature reports, the characteristics of mountain bike muscle endurance athletes torso flexion and extension number is not much, the purpose of this study is to investigate the mountain bike athletes endurance characteristics in the process of constant speed endurance test, rich mountain bike theoretical research of the project, at the same time provide a reference for bike project of core strength training.
