The purpose of this study was to compare three different intervals for a between sets rest period during a common isokinetic knee extension strength-testing protocol of twenty older Brazilian men (66.30 ± 3.92 yrs). The volunteers underwent unilateral knee extension (Biodex System 3) testing to determine their individual isokinetic peak torque at 60, 90, and 120° ·s-1. The contraction speeds an...

BACKGROUND The purpose of this study was to determine and compare the test-retest reliability of quadriceps isokinetic endurance testing at two knee angular velocities in patients with chronic obstructive pulmonary disease (COPD). METHODS After one familiarization session, 14 patients with moderate to severe COPD (mean age 65±4 years; forced expiratory volume in 1 second (FEV1) 55%±18% predic...

This study compared nutritional intake, body composition, bone mineral density, and isokinetic strength by dance type in collegiate female dancers. The study subjects included Korean dancers (n=12), ballet dancers (n=13), contemporary dancers (n=8), and controls (n=12). Nutritional intake was estimated using the Computer Aided Nutritional Analysis Program. Body composition and bone mineral dens...

BACKGROUND Muscle fatigue has high relevance in human performance yet little research has evaluated how it should be assessed. OBJECTIVE To perform a pilot study to identify suitable methods of generating and assessing fatigue of the trunk flexor and extensor muscles. METHODS Sixteen university rugby players (mean (SEM) age 21.9 (0.2) years) were recruited and subjected to four protocols (A...

Background: Behçet’s disease (BD) is an idiopathic, multisystemic, progressive disease. The purpose of this study is to compare the knee flexor and extensor isokinetic muscle strengths of Behcet’s patients with that of healthy subjects. Methods: Twenty-five (13 male and 12 female) patients with BD and 25 (15 male and 10 female) healthy individuals were included in the study. Velocities of 90°/s...

Shoulder isokinetic assessment: A critical analysis B. Forthomme, D. Maquet, J.M. Crielaard and J.L. Croisier Department of Physical Medicine and Rehabilitation, CHU Sart Tilman, Li ège, Belgium Objectives: The literature dealing with shoulder isokinetic assessment presents some contradictions in methodological aspects, protocol design and even muscles targeted [1]. Nevertheless, quantitative a...

Our purpose was to determine if females demonstrate decreased hamstrings to quadriceps peak torque (H/Q) ratios compared to males and if H/Q ratios increase with increased isokinetic velocity in both sexes. Maturation disproportionately increases hamstrings peak torque at high velocity in males, but not females. Therefore, we hypothesised that mature females would demonstrate decreased H/Q rati...

BACKGROUND The relationship between muscle injury and strength disorders remains a matter of controversy. PURPOSE Professional soccer players performed a preseason isokinetic testing aimed at determining whether (1) strength variables could be predictors of subsequent hamstring strain and (2) normalization of strength imbalances could reduce the incidence of hamstring injury. STUDY DESIGN C...
