Uncertainty exists as to whether a period of passive arterial occlusion (PAO) or ischemic exercise (IE) results in peak lower leg vascular conductance (LVC). This uncertainty is due to the different body positions, active muscle mass, and occlusion times used for PAO or IE. The purpose of this study was to examine whether 10 min of PAO elicits a similar LVC compared with ischemic dorsiflexion (...

CONTEXT Inversion ankle sprains can lead to a chronic condition called functional ankle instability (FAI). Limited research has been reported regarding isokinetic measures for the plantar flexors and dorsiflexors of the ankle. OBJECTIVE To examine the isokinetic eccentric torque measures of the ankle musculature in participants with stable ankles and participants with functionally unstable an...

This paper presents a method for robust velocity control of electromagnetic friction brakes constant (isokinetic) training in rehabilitation. Rehabilitation treatments using robots have become an attractive option due to labor shortages. In robot rehabilitation, isokinetic exercises are form highly efficient training. rehabilitation machines, passive machines (brakes and clutches) commonly util...

Knee injury rehabilitation often includes the step-up exercise. However, the authors have been unable to locate documentation of the effect of the step-up exercise on lower extremity strength indices. The purpose of this study was to determine the effect of a six-week lateral step-up exercise protocol on quadriceps muscle group strength. Twenty female nonetheless (age 20 ± 1.5 yrs, ht 162.6 ± 4...

Influence of the dynamometer and knee joint axis of rotation alignment on the isokinetic measurements J.L. Croisier, P. Ciavatta and B. Forthomme Department of Physical Medicine and Rehabilitation, University of Liege, Belgium E-mail: [email protected] Objectives: Factors that could influence accuracy of isokinetic assessment deserve careful attention [1,2]. In order to develop accurate and ...

The purpose of this study was to investigate the effects of caffeine on maximum voluntary contractions of the dominant knee extension and flexion muscles in 12 male intercollegiate track sprinters. Caffeine (5 mg.kg-1) and placebo (225 mg methylcellulose) gelatin capsules were administered orally in randomly assigned order. Muscle function was measured isokinetically by a Cybex II dynamometer i...

OBJECTIVES The ability to maximally generate active muscle tension during resistance training has been established to be a primary determinant for strength development. The influence of intrasession rest intervals may have a profound effect on strength gains subsequent to short-term high intensity training. The purpose of this study was to examine the effects of rest interval on strength and fu...

BACKGROUND This study investigated the effects of Lignosus rhinocerotis (LRS) supplementation and resistance training (RT) on isokinetic muscular strength and power, anaerobic and aerobic fitness, and immune parameters in young males. METHODS Participants were randomly assigned to four groups: Control (C), LRS, RT, and combined RT-LRS (RT-LRS). Participants in the LRS and RT-LRS groups consum...
