We investigated the relationships between power event scores and power/strength tests using the International Association of Athletics Federations (IAAF) scoring table. We sought to identify tests suitable for evaluating the performance of athletes specialized in power events involving different techniques (jumping, sprinting, and throwing). Seventyfour male university-level track and field ath...

BACKGROUND Femoroacetabular impingement (FAI) is a painful and limiting condition of the hip that is often seen in young athletes. Previous studies have reported a higher prevalence of this disorder in male athletes, but data on the structural morphology of adolescent and young adult female athletes, specifically those involved in dance, are lacking. PURPOSE (1) To investigate the radiographi...

Purpose: This study aimed to evaluate the symmetry of the isometric strength of the shoulder and scapulothoracic muscles in volleyball and futsal athletes. Methods: In this case-control study, the strength of the scapulothoracic muscles and rotation of the shoulders in 20 adult volleyball athletes and 20 futsal adult athletes, who were randomly selected from sports clubs around Tehran, were me...

Background. The kinematics of a controlled functional task in female volleyball athletes may be an interesting area of study. Therefore, investigating if there are kinematic changes in a jump landing jump task among female athletes with low back pain (LBP) may help therapists and trainers better prevent and/or rehabilitate LBP in athletes. Objectives. The purpose of this study was to examine l...

PURPOSE The repetitive micro traumatic stresses placed on the athletes shoulder joint complex during the throwing motion challenge the surrounding tissues. The purpose of this study was to compare shoulder rotational strength, range of motion and proprioception between the throwing athletes and non-athletic persons. METHODS Fifteen throwing athletes and 15 non-athletes participated in a nonra...

BACKGROUND The modified Balance Error Scoring System (mBESS) and Y-Balance Test are common clinical measurements of postural control, but little is known about the effect of age on performance of these tasks. The purpose of this study was to examine how healthy child and adolescent athletes perform on 2 common clinical measurements of postural control. HYPOTHESIS Younger athletes would demons...

OBJECTIVE Our purpose was to determine whether sex differences exist with respect to post-concussion symptoms and neurocognitive function in concussed collegiate athletes. METHODS A prospective dependent-sample cohort design was used to compare baseline and post-concussion neuropsychological test scores and endorsed symptoms as functions of serial post-concussion assessment with respect to ti...

The purpose of the research was to compare muscle torque of elite combat groups. Twelve taekwondo WTF athletes, twelve taekwondo ITF athletes and nine boxers participated in the study. Measurements of muscle torques were done under static conditions on a special stand which belonged to the Department of Biomechanics. The sum of muscle torque of lower right and left extremities of relative value...

Intake of dietary supplements is widespread among athletes in developed countries. This study evaluated the use of dietary supplements in athletes from a developing country. Dietary supplementation practices of 113 national-level athletes age 15-35 yr in Sri Lanka were assessed. All athletes from track-and-field, badminton, football, swimming, cycling, and karate squads who consented to partici...
