髋受力下肢力量训练器对人体跑跳极限运动能力最大后蹬力提高的作用★

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 strength training apparatus took part in the experiment 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 pushed foreword by legs.①Multifunction 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.②Comparisons 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.

摘要

背景：人类后蹬力量可能是一种未能有效开发并具有极大开发潜力的动力源,阐明后蹬力量与下肢力量的关系对人体运动科学理论的发展具有重要意义。
目的：观察髋受力下肢力量训练器与最大后蹬力量、最大下肢力量提高的关系。
设计：观察对比分析。
单位：中国海洋大学体育系。
对象：实验于2000－12/2001－11年在中国海洋大学完成，选择94名从未用过髋受力训练器的健康男大学生运动员，平均（19.7±1.7）岁，体质量（75.27±2.93）kg, 所有被试对象均对受试项目知情同意。
方法：随机抽取其中46名受试者为实验组，采用髋受力下肢力量训练器（远固定髋受力下肢力量训练器型号：HNLPT-04Ed；近固定髋受力下肢力量训练器型号：HFLPT-04E，研制单位为中国海洋大学）进行历时11个月的后蹬力量提高训练。其余48名作为对照组采用现有的力量训练方法,即抗阻前蹬和负重蹲起。实验组受试者进行力量练习和测试时，坐于顶髋坐椅上，身体正直。脚踩踏板，按预定角度和轨迹作蹬伸运动。采用近固定机时，练习者的躯干和髋部固定不动，腿蹬踏板向后运动。采用远固机时，踏板和脚不动，髋部和躯干靠腿的蹬伸向前运动。① 采用多功能力量训练器和远固定髋受力下肢力量训练器分别测定94名从未用过髋受力训练器的受试者的最大下肢力量和最大后蹬力量。② 对两组受试对象于训练前后最大下肢力量和最大后蹬力量进行测量比较。
主要观察指标：① 94名从未用过髋受力训练器的受试者最大下肢力量和最大后蹬力量。②实验组及对照组受试对象于训练前后最大下肢力量和最大后蹬力量进行测量比较。
结果：纳入实验组46名及对照组48名受试对象均进入结果分析。①受试者平均后蹬力量为(1 135.53±196.98) N,小于最大下肢力量[(2 414.62±424.05)N，P < 0.01]。②经过11个月的髋受力下肢力量训练法的专项力量训练，实验组受试对象训练前后的最大后蹬力量高于实验前[(1 124.94±206.19)， 1 762.24±193.45] N，P < 0.01],对照组受试对象训练前后的最大后蹬力量差异无统计学意义。
结论：通过髋受力下肢力量训练使后蹬力量获得的提高是现有任何训练方法和训练器所无法获得的人体极限运动能力的提高，可使跑、跳世界纪录大幅度突破成为可能。
