Abstract:
BACKGROUND:The driving strength may be an undiscovered power source with a great developing potential. To clarify the relationship between driving strength and lower limb strength is of great importance to the development of the theory of human movement science.OBJECTIVE: To find out the relationship between the maximal driving strength and the maximal lower limb strength.DESIGN: Observation and contrast analysis.SETTING: Department of Physical Education, Ocean University of China.PARTICIPANTS: A total of 94 male healthy university student athletes were enrolled from Ocean University of China between December 2000 and November 2001, aged (19.7±1.7) years and weighed (75.27±2.93) kg. All the objects that had never used the hip stress strengthtraining apparatus took part in theexperiment voluntarily.METHODS: Forty-six of 94 subjects were randomly selected to take part in an 11-month program of driving strength improvement by using hip stress lower limb strength training apparatus (far fixed hip-stressed lower-limb strength training apparatus and near fixed hip-stressed lower-limb strength training apparatus were manufactured by Ocean University of China, pattern number: HNLPT-04Ed, HNLPT-04E respectively). And other 48 subjects were arranged as the control group using current strength training methods (resistance forward leg extending and barbell squatting). For experimental group to do strength practice and measurement, the object sat on the hip-supporting seat straightly, pressed his hip against the hip-stressed resistant unit and put his feet on the pedals, then extended leg at the preset angle and locus.When the near fixed device was used, the trainee kept his hip and body trunk in a static position, and drove the pedals backward. When the far fixed device was used, the pedals fixed in a static position, the hip and trunk were pushedforeword by legs. ① Multifunction strength training apparatus and far fixed hip stress lower limb strength training apparatus were respectively used to test the maximal lower limb strength and maximal driving strength of 94 objects.② Comparisons between before and after training in two groups were made in the maximal driving strength and the maximal low limb strength.MAIN OUTCOME MEASURES: The maximal leg strength and leg driving strength of 94 healthy subjects before and after training.RESULTS: All the 46 subjects in experiment group and the 48 subjects in control group were involved in the result analysis.①The maximal driving strength was lower than the maximal leg strength [(1 135.53±196.98) N, (2 414.62± 424.05) N, P ＜ 0.01].②After the 11-month special training with hip stress lower limb strength training apparatus, the maximal driving strength of experiment group got a significant increase [(1 124.94±206.19), (1 762.24±193.45) N, P ＜0.01]. No significant differences were found in the control group.CONCLUSION: The increase of driving strength from the hip stress lower limb strength training may be an increase of athletic capability that can never be achieved by any current strength training method and apparatus. The application of this method will make it possible to realize great breakthrough of world sports records in the events of running and jumping.
