Training Effect of Isotonic Concentric and Eccentric Contraction of Elbow Flexors in Different Combinations

Training Effect of Isotonic Concentric and Eccentric Contraction of Elbow Flexors in Different Combinations

In order to determine a rational protocol for isotonic training from macroscopic angle, five training protocols were designed, particularly protocols composed of pure eccentric contraction with heavy resistance in different propotions. The study results indicated that the protocol mixed with faster speed eccentric training,being more rational than traditional isotonic training and pure isotonic eccentric training, had the most all - round effects(including change of musle size, isotonic strength, musle power and et al. ). The protocol principle mixed with faster speed eccentric training may be widely used in rehabilitation and sports training,especially in the sports events of strength resistance. The significance to study the ratio of eccentric contaction to concentic contraction was suggested.
