The Main Muscle Surface EMG Characteristics of the Rowing Athletes' in Different Roads

Abstract

Objective: Through the man rowing open athletes of Hubei province for ergometry test of 3 minutes for 60% and 90% maximum load, this article aims to understand the rowing open athletes in ergometry test of main muscle group strength distribution ratio, fatigue and strength characteristics. Methods: 6 man rowing open athletes of Hubei province were chosen for ergometry test of different load test (3minutes for 60% and 90% maximum load). The characterization of surface electromyographic changes was tested in the major exertor muscles, medial head of quadriceps and tibialis anterior muscles. Results: The results showed that: Maximum load test increased from 60% to 90%; IEMG appeared significant difference (P<0.05); especially the latissimus dorsi showed very significant difference (P<0.01); MF and MPF changed little. Conclusion: 60% load intensity achieves a good training effect on the calf muscles, and 90% load intensity acts on the training of the lower limb muscles.
