OBJECTIVE The objective was to determine the effect of trunk focused neuromuscular training (TNMT) on hip and knee strength. The hypothesis was that TNMT would increase standing isokinetic hip abduction, but not knee flexion/extension, strength. METHODS 21 high-school female volleyball players (14 TMNT, mean age 15.4 (1.4) years, weight 170.5 (5.0) cm, height 64.1 (8.5) kg and 7 controls, mea...

Objectives: The aim of this investigation was to assess the use of isometric strength testing as a determinant of sprint and change of direction performance in collegiate athletes. Design and Methods: Fourteen male collegiate athletes (mean ± SD; age = 21 ± 2.4 years; height =176 ± 9.0 cm; body mass = 72.8 ± 9.4 kg) participated in the study. Maximal strength was assessed via an isometric mid-t...

OBJECTIVES To determine the effect of prophylactic treatment with an inhaled bronchodilator and anti-inflammatory on arterial saturation (SaO2) in trained non-asthmatic male athletes with exercise induced arterial hypoxaemia (EIAH). METHODS Nine male athletes (mean (SD) age 26.3 (6.7) years, height 182.6 (7.9) cm, weight 79.3 (10.5) kg, VO2MAX 62.3 (6.3) ml/kg/min, SaO2MIN 92.5 (1.1)%) with n...

OBJECTIVE To determine the magnitude of the effects of pectus excavatum deformity on endurance fitness and cardiorespiratory functional reserve in adolescent boys. DESIGN Cross-sectional comparison of cardiac and ventilatory variables at rest and during a maximal cycle exercise test. SETTING Pediatric exercise-testing laboratory. PARTICIPANTS Twelve boys (mean +/- SD age, 14.1 +/- 1.8 yea...

The objectives of this study were to develop a specific formula to estimate age in a Brazilian adult population and to compare the original formula from Cameriere to this Brazilian formula. The sample comprised 1,772 periapical radiographs from 443 subjects (219 men, 224 women) that were organized into 12 groups according to sex (men or women) and age (20-29, 30-39, 40-49, 50-59, 60-69, and 70 ...

performance of heart has substantial role in breaking records of sports. achieving to optimal performance of endurance training builds upon the consistency in several parts of body specially heart. type, intensity, term training programs is determining components of providing structural consistency and performance of heart especially in left ventricular. aim of this research was comparing struc...

BACKGROUND Femoroacetabular impingement (FAI) is a common cause of hip pain and dysfunction among athletes. Although arthroscopic surgery is an established treatment option for FAI, there are few studies reporting detailed outcomes using validated outcome measurements specifically designed for young and active athletes. PURPOSE To report outcomes 1 year after arthroscopic treatment of FAI in ...

purpose oligo/amenorrhea, as a part of the female athlete triad has adverse effects on the athlete's bone mineral density (bmd) and cardiovascular system. hypoestrogenism, due to suppression of hypothalamus-pituitary axis (hpa) as a result of energy imbalance, is the possible cause of the triad. this study was designed based on following up and reassessment of elite female athletes who were dia...
