To investigated whether an acute hypoxic stimulus affects muscle strength development assessed by isokinetic dynamometry during maximal knee extension. A total of 15 healthy young men participated in this study (61.9 ± 6.1 kg; 1.72 ± 0.08 m; 20.9 ± 2.6 years). We evaluated knee extension and flexion isokinetic dynamometer performance in normoxic and hypoxic conditions. The analyzed parameters, ...

OBJECTIVE The objective of this work is to present an objective, practical, and reproducible method for evaluating the functional limitation caused by occlusive arterial disease in upper limbs: a stress test using an isokinetic dynamometer. METHODS Twenty-three patients with unilateral subclavian artery occlusive disease were included in the study, forming group 1. Seven patients of similar a...

BACKGROUND The purpose of this study was to evaluate the clinical outcomes and objective isokinetic dynamometry on a cohort of patients with chronic insertional Achilles tendinosis, who underwent surgical reconstruction using an FHL tendon autograft transfer through a single incision. MATERIALS AND METHODS Forty patients (16 male and 24 female; mean age, 57 years; age range, 39 to 76 years) w...

Background: Isokinetic dynamometry allows the measurement of several variables related to muscular performance, many of which are seldom used, while others are redundantly applied to the characterization of muscle function. Objectives: The present study aimed to establish the particular features of muscle function that are captured by the variables currently included in isokinetic assessment an...

OBJECTIVE The present study assessed the reliability and validity of isokinetic dynamometry in the qualitative determination of the evolution of total knee arthroplasty. CASES 20 patients whose mean age was 71.35 years, undergoing knee arthroplasty, and 25 controls whose mean age was 71.36 years. METHOD Computerized isokinetic assessment of flexor and extensor muscles using a CYBEX 6000 dyn...

A plethora of research has examined bilateral and reciprocal concentric strength relationships of the thigh musculature in a variety of athletic populations. However, little research has reported strength values of the trunk and hip musculature. Thus, the purpose of this investigation was to examine concentric and eccentric strength of the trunk and hip flexor and extensor muscle groups in fema...

The aim of this paper was to outline a multilevel modeling approach to fit individual angle-specific torque curves describing concentric knee extension and flexion isokinetic muscular actions in Master athletes. The potential of the analytical approach to examine between individual differences across the angle-specific torque curves was illustrated including between-individuals variation due to...
