OBJECTIVE To investigate the effects of moderate-intensity and low frequency exercise on resting serum testosterone and cortisol levels, resting heart rate, and isokinetic strength among healthy sedentary young men. DESIGN A randomized controlled study. Forty sedentary young men aged 18 to 25 years old, pedaled 50 minutes on a bicycle ergometry at 60% of maximal effort once a week for 12 week...

OBJECTIVE To investigate the effects of glenohumeral internal rotation deficit (GIRD) on the isokinetic strength, body pain, and the quality of life in male high school baseball players of Korea. METHODS Fifty-six male high school baseball players were divided into either group A (GIRD≥20°, n=12) or group B (GIRD<20°, n=44). The range of motion in the shoulder and the isokinetic strength were...

Maximal weight-lifting performance, isometric strength, isokinetic torque, whole muscle and individual fiber cross-sectional areas, and muscle evoked contractile properties were assessed in 14 elderly males before and after 12 wk of weight-lifting training. Dynamic elbow flexion training of one arm resulted in a significant 48% mean increase in the maximal load that could be lifted once (1 RM) ...

BACKGROUND Conservative treatments have been proposed for people with shoulder impingement syndrome (SIS), such as strengthening of the rotator cuff and scapular muscles and stretching of the soft tissues of the shoulder. However, there is a lack of studies analyzing the effectiveness of eccentric training in the treatment of SIS. OBJECTIVES To evaluate the effects of eccentric training for s...

Objective: This study aimed to compare and evaluate the efficacy of eccentric concentric training on quadriceps femoris muscle architecture, strength proprioception in healthy young people. &#x0D; Materials Methods: Sixty subjects were divided into two groups (n=30), (n=30). The outcome measurements Quadriceps Femoris (QF) knee proprioception. was carried out subjects’ dominant side leg (right)...

BACKGROUND: Isokinetic testing is often used to provide coaches with important information about the physical status of athletes. Therefore, a number of studies is focused on the assessment of the relationship between isokinetic and functional tests. The results of a limited number of studies indicate that the relationship changes in different training periods. OBJECTIVE: The aim of the study w...

A study of isokinetic exercise and isotonic variableresistance training divided 12 individuals into four groups: 1) control; 2) isotonic variable-resistance training; 3) low-speed isokinetic (5, 10, and 15 rpm); and 4) high-speed isokinetic training (30, 40, and 50 rpm). All exercised groups showed good gains in strength when tested isometrically, isotonically, and isokinetically. However, when...
