DESIGN Randomized controlled study. SETTING Laboratory. PARTICIPANTS 26 healthy swimmers randomly assigned to an exercise (n = 13; Ex) or control group (n = 13; Cont). INTERVENTION The Ex group performed respiratory-muscle exercises for 10 min thrice a week for 4 wk. CONTEXT Respiratory-muscle exercises are used not only in the rehabilitation of patients with respiratory disease but als...

OBJECTIVES The study of cervical muscles and their significance in the development and perpetuation of Temporomandibular Disorders has not been elucidated. Thus this project was designed to investigate the association between cervical musculoskeletal impairments and Temporomandibular Disorders. MATERIAL AND METHODS A sample of 154 subjects participated in this study. All subjects underwent a ...

STUDY DESIGN Test-retest design. OBJECTIVE The objective was to examine the intrarater (test-retest) reliability of the core stability related tests and to develop a reliable core stability assessment battery. SUMMARY OF BACKGROUND DATA Studies suggest that core stability exercises may improve function and decrease pain in patients with nonspecific low back pain (LBP). Reliable clinical tes...

PURPOSE The purpose of this study was to determine the effects of increasing training volume from one set to three sets on muscular strength, muscular endurance, and body composition in adult recreational weight lifters. METHODS Forty-two adults (age 39.7 +/- 6.2 yr; 6.2 +/- 4.6 yr weight training experience) who had been performing one set using a nine-exercise resistance training circuit (R...

INTRODUCTION The relationship between skeletal muscle strength and respiratory dysfunction in Pompe disease has not been examined by quantitative methods. We investigated correlations among lower extremity proximal muscle strength, respiratory function, and motor performance. METHODS Concentric strength of the knee extensor and flexor muscles was measured with a dynamometer, and pulmonary fun...

PURPOSE Fifteen elite male handball players were studied to examine the effects of an entire season of play on physical fitness and throwing velocity. METHODS One repetition maximal bench press (1RMBP), jumping explosive strength, power-load relationship of the leg and arm extensor muscles, 5- and 15-m sprint running time, endurance running, and handball throwing velocity (standing and three-...

background: alterations in the neuromuscular control of the spine were found in patients with chronic low back pain (clbp). sudden loading of the spine is assumed to be the cause of approximately 12% of lower back injuries. however, some aspects of this problem, such as alterations in the sensory–motor control of the spine, remain questionable. this study investigated postural and neuro–motor c...
