Anthropometric and muscle strength evaluation in prepubescent and pubescent swimmers and muscle strength and body composition are important for a better sporting performance. The objective of this study was to describe and to compare anthropometrical and muscle strength aspects of prepubescent and pubescent swimmer boys and girls. Forty-eight healthy competitive swimmers participated in this st...

Isokinetic resistance is frequently used to strength profile healthy athletes and to evaluate the status of injured athletes involved in rehabilitation programs. The purpose of this investigation was to determine the reliability of peak torque, torque acceleration energy, endurance ratio, average power, and total work measures obtained with a Cybex isokinetic dynamometer. Fifteen college studen...

OBJECTIVE To investigate pulmonary function, working capacity and isokinetic muscle strength in subjects with Marfan syndrome. MATERIALS AND METHODS Seventeen subjects, mean age 23 years, performed spirometry, maximal ergometer cycle tests and knee extension and flexion isokinetic torque tests. RESULTS The subjects with Marfan syndrome had increased total and residual lung volume values com...

–One of the approaches to evaluate injury prediction is the hamstrings-to-quadriceps peak torque conventional ratio (H:Q ratio). The gold standard for assessment of muscle strength in vivo is by isokinetic dynamometry; however, the one-repetition maximum strength test (1-RM) presents high correlation with isokinetic data. This study aimed to compare measures of H:Q ratio in young adults obtaine...

BACKGROUND Recent studies have found a significant deficit of maximum quadriceps strength after autologous chondrocyte implantation (ACI) of the knee. However, it is unclear whether muscular strength deficits in patients with cartilage damage exist prior to operative treatment. PURPOSE To isokinetically test maximum quadriceps muscle strength and quantify the impact of possible strength defic...

Running is a very popular activity and muscle strength imbalance has been treated with caution to prevent injuries. The present study aimed compare correlate knee flexion extension based on peak torque (PT) total work (TW) in running athletes. Thirty-eight male amateur athletes (38 ± 6 years; 80.6 8.3 kg; 177 7 cm; 7.8 8.4 years of training; 3.5 0.9 training sessions week; 33.5 13.4 km per week...

The aim of the study was to determine the profile of isokinetic strength of elite young soccer players (n = 12, mean age 17.5 ± 1.5 years). Assessment was performed on the isokinetic dynamometer. We evaluated: maximum peak muscle torque of knee extensors (PTE) and flexors (PTF) in both legs, ipsilateral ratio of muscle torque for both preferred and non-preferred extremities (H:QP and H:QN, resp...

INTRODUCTION Occupational injuries of the shoulder joint are of growing concern due to work time loss, as well as increases in medical and restitution expenses [1]. The assessment of shoulder musculature strength may assist in decision making regarding the effects of interventions, as well as possible readiness to return to work. Current practices related to the use of strength scores for such ...
