Although spaceflight and bed rest are known to cause muscular atrophy in the antigravity muscles of the legs, the changes in sympathetic and cardiovascular responses to exercises using the atrophied muscles remain unknown. We hypothesized that bed rest would augment sympathetic responses to isometric exercise using antigravity leg muscles in humans. Ten healthy male volunteers were subjected to...

The purpose of this study was to investigate the influence of fatiguing exercise intensity on the nature and extent of fatigue-induced changes in neuromuscular function and postural stability in quiet standing. We also explored the contribution of selected neuromuscular mechanisms involved in force production to postural stability impairment observed following fatigue using an approach based on...

Purpose: Many patients with Achilles Tendinopathy do not respond to eccentric training. The aim of the present case report is to find out the effect of eccentric concentric training of gastrocnemius and soleus combined with isometric contraction of gastrocnemius and static stretching exercises of gastrocnemius and soleus on pain and disability in a patient experiencing Achilles Tendinopathy. Me...

Background & aim: One of the most common causes of back deformities is spinal curve change in the waist. Physical therapy is one of the most common methods for treatment of lordosise and back pain. In the field of corrective exercise, the comparison of Williams and McKenzie’s training findings are small and inconsistent. So, the purpose of this study was to compare the effects of 8 weeks of Wil...

Weakness of the hip abductors after total hip arthroplasty may result in pain and/or functional limitation. Non-weight-bearing (NWB) exercises are often performed to target the hip abductors; however, muscle activation of NWB exercises has not been compared to weight-bearing (WB) exercises. Our purpose was to evaluate gluteus medius activation during 2 WB and 2 NWB hip abductor strengthening ex...

Movements generated by muscle contraction generally include periods of muscle shortening and lengthening as well as force development in the absence of external length changes (isometric). However, in the specific case of resistance exercise training, exercises are often intentionally designed to emphasize one of these modes. The purpose of the present study was to objectively evaluate the rela...

Aims: Active and progressive resistance training has a key role in functional recovery and quality of life in patients with MS. Therefore, this study aimed to investigate the effects of isotonic and isometric exercises on balance and ability in patients with MS. Materials & Methods: In this randomized clinical trial, 60 patients with MS admitted to MS Special Diseases Center in Yasuj during 20...
