Aim: To compare the effect of isometrics, isotonic concentric and eccentric strengthening techniques on patients diagnosed with subacromial impingement syndrome. Methods: The study design used is randomized clinical trial. 36 are allocated in 3 groups 12 each group age limit from 30-50 years treated for 6 weeks alternate days baseline exercise plan respectively. Each patient received 18 session...

Previous research has demonstrated the importance of both dynamic and isometric maximal strength and rate of force development (RFD) in athletic populations. The purpose of this study was to examine the relationships between measures of isometric force (PF), RFD, jump performance and strength in collegiate football athletes. The subjects in this study were twenty-two men [(mean ± SD):age 18.4 ±...

Sport health care professionals are always trying to increase muscle activation while instructing exercises that are functional to the sport performance. However, the traditional core exercises are the ones typically performed. This study examined the muscle activation of the lumbopelvic hip complex during traditional core stability exercises and that of the sports performance movements using t...

STUDY DESIGN Prospective single-group repeated-measures design. OBJECTIVES To quantify electromyographic (EMG) muscle activity of the infraspinatus, teres minor, supraspinatus, posterior deltoid, and middle deltoid during exercises commonly used to strengthen the shoulder external rotators. BACKGROUND Exercises to strengthen the external rotators are commonly prescribed in rehabilitation, b...

BACKGROUND Back extension exercises are often used in the rehabilitation of low back pain. However, at present it is not clear how the posterior muscles are recruited during different types of extension exercises. Therefore, the present study will evaluate the myoelectric activity of thoracic, lumbar and hip extensor muscles during different extension exercises in healthy persons. Based on thes...

BACKGROUND Prone, supine, and side position exercises are employed to enhance core stability. HYPOTHESIS Overall core muscle activity would be greater in prone position exercises compared with supine and side position exercises. STUDY DESIGN Controlled laboratory study. METHODS Eighteen men and women between 23 and 45 years of age served as subjects. Surface electrodes were positioned ove...

PURPOSE To compare the metabolic parameters, body composition and muscle strength of women with Polycystic Ovary Syndrome (PCOS) to those of women with ovulatory menstrual cycles. METHODS A case-control study was conducted on 27 women with PCOS and 28 control women with ovulatory cycles, aged 18 to 27 years with a body mass index of 18 to 39.9 kg/m², who did not practice regular physical acti...

PURPOSE The purpose of this study was to investigate whether foam roller, preexhaustion, and static stretching had any effect on isometric muscular endurance the finger flexors climbing performance in sport climbers. METHODS Nine climbers who were able perform at a difficulty 5.11d, included study. Warm-up exercise consisted myofascial release, pre-exhaustion exercises, stretching. Grip back st...
