background: the purpose of the present study was to investigate the effect of endurance training on amount of nicotinic acetylcholine receptors (nachr) in fast and slow twitch muscles of male wistar rats. methods: a number of 15 male wistar rats randomly divided into two groups of control (n=7) and endurance training (n=8). the endurance training treadmill running (for 12 consecutive week, 5 da...

It is not clear whether the strength or endurance of thigh muscles (quadriceps and hamstring) is positively or negatively correlated with the adduction moment of osteoarthritic knees. This study therefore assessed the relationships between the strength and endurance of the quadriceps and hamstring muscles and adduction moment in osteoarthritic knees and evaluated predictors of the adduction mom...

To compare training programs for women with trapezius myalgia regarding physical performance and pain, 102 women were randomized to strength, endurance, co-ordination and non-training groups. Before and after the intervention, static strength and dynamic muscular endurance in shoulder muscles were measured on a Cybex II dynamometer. Muscle activity in shoulder muscles was monitored via surface ...

Significant levels of muscular fatigue alter the co-ordination patterns and the ability to accomplish proper daily functions, especially in patients with initial low levels of strength. The purpose of this study was to evaluate the strength and endurance of the quadriceps and hamstring muscles in trans-tibial amputees. Concentric strength and endurance of the thigh muscles were measured bilater...

Abdominal bracing is often adopted in fitness and sports conditioning programs. However, there is little information on how muscular activities during the task differ among the muscle groups located in the trunk and from those during other trunk exercises. The present study aimed to quantify muscular activity levels during abdominal bracing with respect to muscle- and exercise-related differenc...

purpose the purpose of the present study was to evaluate effects of regular practice of sun salutation on muscle strength, general body endurance and body composition. methods subjects (49 male and 30 female) performed 24 cycles of sun salutation, 6 days a week for 24 weeks. upper body muscle strength was determined by 1 repetition maximum (1rm) for bench press and shoulder press technique. bac...

The most prominent feature of sheet material forming process is an elastic recovery phenomenon during unloading which leads to springback and side wall curl. Therefore evaluation of springback and side wall curl is mandatory for production of precise products. In this paper, the effects of some parameters such as friction coefficient, sheet thickness, yield strength of sheet and blank-holder fo...
