QUESTION Is an injury prevention program consisting of 10 exercises designed to improve stability, muscle strength, co-ordination, and flexibility of the trunk, hip and leg muscles (known as The11) cost effective in adult male amateur soccer players? DESIGN Cost-effectiveness analysis of a cluster-randomised controlled trial. PARTICIPANTS 479 adult male amateur soccer players aged 18-40 yea...

Introduction. Time-under-tension (TUT) reflects time under load during strength training and is a proxy of the total exercise dose during strength training. The purpose of this study was to investigate if young participants are able to reproduce TUT and exercise form after two weeks of unsupervised exercises. Material and Methods. The study was an assessor-blinded intervention study with 29 par...

The purposes of this study were to document relative activation intensities of the hamstrings and gluteus maximus during 4 eccentric hamstring strengthening exercises and to assess the effects of a short-term strengthening program comprised of these exercises on knee flexor strength and the length-tension relationship. Twelve healthy subjects participated in this study. Electromyographic (EMG) ...

BACKGROUND AND PURPOSE A programme based on eccentric exercises for treating subacromial pain was in a previous study found effective at 3-month follow-up. The purposes of the present study were to investigate whether the results were maintained after 1 year and whether the baseline Constant-Murley score, rotator cuff status and radiological findings influenced the outcome. PATIENTS AND METHO...

The contraction of skeletal muscle (SM) plays an important role in providing power for the body to participate physical activities. Nevertheless, unaccustomed motions, especially eccentric exercises (EE), might cause changes ultrastructure and mitochondria SM, increasing potential risks injuries. objective this narrative literature review was summarize effects EE on SM ultrastructure. results f...

Exercise or Swiss balls are increasingly being used with conventional resistance exercises. There is little evidence supporting the efficacy of this approach compared to traditional resistance training on a stable surface. Previous studies have shown that force output may be reduced with no change in muscle electromyography (EMG) activity while others have shown increased muscle EMG activity wh...

BACKGROUND Shoulder pain is the third most common musculoskeletal disorder, often affecting people's daily living and work capacity. The most common shoulder disorder is the subacromial impingement syndrome (SIS) which, among other pathophysiological changes, is often characterised by rotator cuff tendinopathy. Exercise is often considered the primary treatment option for rotator cuff tendinopa...

BACKGROUND Total, single repetition and contraction-phase specific (concentric and eccentric) time-under-tension (TUT) are important exercise-descriptors, as they are linked to the physiological and clinical response in exercise and rehabilitation. OBJECTIVE To investigate the validity and reliability of total, single repetition, and contraction-phase specific TUT during shoulder abduction ex...
