Abstract


Research purposes: different level of training men for short-distance cyclist lower limb knee, ankle flexion and extension muscle group isokinetic testing to the heart, to study its lower extremity knee, ankle flexion and extension muscle strength, flexion and extension of the ratio of muscle strength and muscle peaks torque angle, exploring different training level of the men's short-distance cyclist knee, and ankle flexion muscles mechanical characteristics, improve athletic performance for athletes avoid sports injuries, to provide a scientific basis for the scientific selection and diagnosis of muscle strength. Methods: In this study, Shanxi Province, 28 men's short-distance cyclist (one more than 12, two 16 below) as the research object, instrument use the CYBEX-770 type isokinetic strength testing rehabilitation system. The main experimental test method, mathematical statistics and other research methods knee, ankle flexion and extension of the men's short-distance cyclist lower limb muscle strength characteristics of the study. Results: In the test angular velocity of 60 ° / s (maximum force), one more than the men's short-distance cyclist left, right knee extensor peaks torque value greater than two athletes (P <0.05) ; more than one man short distance cyclist knee flexor right side of the peaks of the torque was significantly greater than the two following athletes (P <0.01); two men's short-distance cyclist the left knee extensor peaks torque obvious large on the right side (P <0.01). Test angular velocity of 300 ° / s (fast hard), one above and two below the men's short-distance cyclist extensor group than flexors relative peak torque decline. 3 test angular velocity of 60 ° / s, the following two men short distance cyclist left ankle dorsiflexion plantar flexor peaks torque is greater than the right side (P <0.05), and a more significant difference. 4 test angular velocity of 60 ° / s and 180 ° / s (fast hard), a men's short-distance cyclist right ankle dorsiflexors peaks torque was significantly greater than the two athletes (P < 0.01). Conclusions and recommendations: two men's short-distance cyclist left, right knee extensor group and right flexor muscle strength needs to be improved. Two men's short-distance cyclist left and right side of the knee extensor group development imbalances, should strengthen the training of the forces of the right side of the knee extensor group, as well as early correct pedaling tactless. (2) one above and two below the men's short-distance cyclist quickly force the knee extensor group persistence is not strong, we should strengthen the the fast strength of the knee extensor group continued training. 3. Two men short distance cyclist left and right ankle dorsiflexion plantar flexors uneven development, the right ankle dorsiflexion plantar flexors maximum force needs to be improved. 4 two men a short distance cyclist should focus on the development of ankle dorsiflexion maximum muscle strength and rapid strength exercises.
