Morphometric and Molecular Muscle Remodeling after Passive Stretching in Elderly Female Rats

Effects of passive stretching on muscle injury and HSP expression during recovery after immobilization in rats.

OBJECTIVE Stretching exercise is known to induce muscle hypertrophy and is implicated in the modulation of muscle fiber behavior. We aim to determine whether stretching exercise is protective against reloading-induced muscle damage in immobilized rat soleus muscle. METHODS Rat hindlimbs in 54 eight-week-old male Wistar rats were immobilized by cast for 4 weeks, followed by reloading alone thr...

Altered reflex sensitivity after repeated and prolonged passive muscle stretching.

Experiments were carried out to test the effect of prolonged and repeated passive stretching (RPS) of the triceps surae muscle on reflex sensitivity. The results demonstrated a clear deterioration of muscle function immediately after RPS. Maximal voluntary contraction, average electromyographic activity of the gastrocnemius and soleus muscles, and zero crossing rate of the soleus muscle (record...

Effect of Active Dynamic Versus Passive Static Stretching on Hamstring Muscle Tightness in Healthy Female Students: A Randomized Trial Study

Background: For decades, static stretching has been the standard benchmark for training programs, because it has been shown to increase flexibility compared with other methods of stretching. Objective: The current study investigated and compared the effects of active dynamic stretching and passive static stretching on hamstring tightness. Me...

Acute effects of passive muscle stretching on sprint performance.

The results of previous research have shown that passive muscle stretching can diminish the peak force output of subsequent maximal isometric, concentric and stretch-shortening contractions. The aim of this study was to establish whether the deleterious effects of passive stretching seen in laboratory settings would be manifest in a performance setting. Sixteen members (11 males, 5 females) of ...
