利用等速测试及康复系统对优秀水球运动员膝关节肌群进行等速向心收缩测试与分析,结果发现,峰力矩可作为评价水球运动员膝关节肌力大小的一个敏感指标,峰力矩值越大,肌肉做功能力越强,做功效率越高。水球运动员膝关节慢速肌力与快速肌力呈非常显著相关,其左右膝关节肌力相当平衡,快速屈伸肌比率大于慢速屈伸肌,屈肌的慢速力量较弱。  相似文献

将38名女性被试随机分组进行等动向心和离心训练,通过对被试进行等动向心和离心训练,对被试的膝关节的屈伸力矩和力矩的增长率进行分析评价.训练内容包括对被试的非优势腿的膝关节的伸膝肌群和屈膝肌群进行为期20周,每周三次的等动向心和离心训练(SD=1),研究结果发现离心训练组被试伸膝肌群和屈膝肌群的峰力矩的增长幅度远大于向心训练组.与向心训练组相比,离心训练组缩短了力矩加速期以及达到峰力矩的时间.在对被试进行的20周的训练过程中,与向心训练相比,慢速等动离心训练能更有效的提高离心收缩时的力矩,而在完成向心收缩时力矩的增长情况与向心训练组相似.  相似文献

在现有条件下为寻求等速运动肌电图研究的方法，探讨股四头肌各头在膝关节不同角度、不同运动速度时肌电变化的特点，以16名男青年为试验对象，分别在BIODEX等速测力计及膝关节练习器上测定坐位伸膝肌力和股四头肌表面3个头的肌电图，对肌电积分值等指标进行分析。初步了解了等速运动肌力、肌电指标的变化规律；发现用肌电积分值百分比来分析股四头肌表面3个头对伸膝发力的贡献，虽有很大个体差异，但不同运动速度、不同关节运动角度、不同侧肢体等因素对其均无明显影响，可用于康复功能评定。此外，还对不同伸膝练习的作用和膝关节急慢性损伤等速运动肌电图的改变进行了初步探讨。  相似文献   

Core stability training on lower limb balance strength     

Antonio Dello Iacono  Johnny Padulo  Moshe Ayalon 《Journal of sports sciences》2016,34(7):671-678

This study aimed to assess the effects of core stability training on lower limbs’ muscular asymmetries and imbalances in team sport. Twenty footballers were divided into two groups, either core stability or control group. Before each daily practice, core stability group (n = 10) performed a core stability training programme, while control group (n = 10) did a standard warm-up. The effects of the core stability training programme were assessed by performing isokinetic tests and single-leg countermovement jumps. Significant improvement was found for knee extensors peak torque at 3.14 rad · s^?1 (14%; P < 0.05), knee flexors peak torque at 1.05 and 3.14 rad · s^?1 (19% and 22% with P < 0.01 and P < 0.01, respectively) and peak torque flexors/extensors ratios at 1.05 and 3.14 rad · s^?1 (7.7% and 8.5% with P < 0.05 and P < 0.05, respectively) only in the core stability group. The jump tests showed a significant reduction in the strength asymmetries in core stability group (?71.4%; P = 0.02) while a concurrent increase was seen in the control group (33.3%; P < 0.05). This study provides practical evidence in combining core exercises for optimal lower limbs strength balance development in young soccer players.  相似文献   

Relative appendicular skeletal muscle mass is associated with isokinetic muscle strength and balance in healthy collegiate men

There are few studies on the relationship between skeletal muscle mass and balance in the young ages. We investigated the relationship between appendicular skeletal muscle mass, isokinetic muscle strength of lower extremity, and balance among healthy young men using relative skeletal muscle index. Thirty men were grouped according to relative appendicular skeletal muscle mass index: higher skeletal muscle group (n = 15) and lower skeletal muscle group (n = 15). Static and dynamic balance abilities were measured using the following: a test where participants stood on one leg with eyes closed, a modified Clinical Test of Sensory Interaction on Balance (mCTSIB) with eyes open and eyes closed, a stability test, and limits of stability test. The muscle strength of lower extremities was measured with an isokinetic analyser in hip, knee, and ankle joints. Participants with higher appendicular skeletal muscle mass were significantly more stable in maintaining dynamic balance than those with lower appendicular skeletal muscle mass. Moreover, appendicular skeletal muscle mass index was positively correlated with dynamic balance ability. Participants with higher appendicular skeletal muscle mass had stronger strength in the lower extremity, and there were significant differences in the isokinetic torque ratios between groups. From these results, it can be inferred that higher appendicular skeletal muscle mass relates to muscle strength and the alteration in the peak torque ratio of the lower extremity, contributing to the maintenance of balance.  相似文献

为探讨沙滩排球训练对运动员膝、踝关节肌群肌力的影响,沙滩排球训练周期前后,对我国１２名兼职沙滩女排运动员的膝、踝关节肌群进行了ＢＩＯＤＥＸ肌力测试。结果表明,沙滩训练后,膝关节屈肌群快肌纤维的爆发力,伸肌群快肌纤维的最大力和爆发力,踝关节跖肌群慢、快肌纤维的最大肌力和爆发力增长有显性意义,这是沙滩训练后原地纵跳成绩提高的重的肌力原因。  相似文献   

Elite male field hockey players have symmetric isokinetic glenohumeral strength profiles,but show asymmetry in scapular muscle strength

Shoulders of elite field hockey players are loaded continuously during play. However, shoulder girdle muscle performance in this population has never been examined yet. This study aimed to compare isokinetic shoulder girdle performance in elite male field hockey players to matched controls, with respect to strength, endurance and muscle balance. The complete male national field hockey team of Belgium (n = 25) was included and matched to a gender- and age-matched control group of healthy participants (n = 25). A Biodex system-4 dynamometer was used to measure glenohumeral and scapular muscle strength at 2 velocities in a concentric/concentric mode. With the main outcome measures being isokinetic strength values, peak force (protraction-retraction), peak torque (rotations), fatigue index and agonist/antagonist ratio’s. Measurement results showed that elite male field hockey players were stronger than their matched controls, for both the rotational and the protraction-retraction movement. Concerning rotational strength, symmetrical findings were established, contrary to scapular strength, where side differences were noted. At low velocity, retraction peak force was higher on the dominant side. Protraction peak force was higher on the non-dominant side when measured at high velocity. In conclusion, elite field hockey players have a symmetrical rotational strength profile, in contrast to their scapular strength profile.  相似文献
