cold water immersion after damaging exercise delays the peak expression of hsp25 protein

چکیده
it is generally believed that unaccustomed exercise causes myofibrillar damage. in recent years, cold water immersion (cwi) following heavy training sessions and matches has been common aiming at reducing soreness. however, there is no strong scientific rationality if this method really accelerates recovery after exercise. in addition, there is a question that if it is possible for this method to interfere in short-term adaptations resulted from exercise. hsp25, as one of the stress proteins that has been shown to play an important role in the remodeling process of recovery after damaging exercise, was discussed in this study. the aim of this study was to investigate the expression of hsp25 protein following cold water immersion after damaging exercise in different recovery time courses. 96 male wistar rats (weight 290±10 gr and age 8-9 weeks old) were divided into two groups of exercise (ex) and exercise followed by cold water immersion (ex+cwi). each group was divided into 6 subgroups in different time courses before and after the exercise (before, 0.5, 24, 48, 72, and 168 hours after the exercise). the exercise protocol consisted of 45 minutes of running in a treadmill with incline (speed: 20 m/min. and incline: -17 degrees) and the cold water protocol consisted of 10 minutes of immersion in 10̊ water. the hsp25 protein of skeletal soleus was measured by elisa method in different time courses. analysis of variance was used to analyze the data within a group while independent t test was sued to compare the data among the groups in different time courses. the significance level was considered 0.05. it was observed that the hsp25 protein increased significantly in all time courses except for 168 hours after the exercise (p

Cognitive Performance Is Enhanced during Cold-water Immersion and Exercise
for normally hydrated individuals. However, when working in stressful environments for extended durations, particularly when wearing personal protective equipment, fluid losses via sweat secretion are dramatically elevated, and can approach 8-16 L.day -1 . Indeed, during a moderate exercise-heat stress, whole-body sweat rates typically range between 1-1.5 L.h -1 , and fluid loss at this rate si...
متن کاملCold water immersion enhances recovery of submaximal muscle function after resistance exercise.
We investigated the effect of cold water immersion (CWI) on the recovery of muscle function and physiological responses after high-intensity resistance exercise. Using a randomized, cross-over design, 10 physically active men performed high-intensity resistance exercise followed by one of two recovery interventions: 1) 10 min of CWI at 10°C or 2) 10 min of active recovery (low-intensity cycling...
متن کاملCold-water immersion (cryotherapy) for preventing and treating muscle soreness after exercise.
BACKGROUND Many strategies are in use with the intention of preventing or minimising delayed onset muscle soreness and fatigue after exercise. Cold-water immersion, in water temperatures of less than 15°C, is currently one of the most popular interventional strategies used after exercise. OBJECTIVES To determine the effects of cold-water immersion in the management of muscle soreness after ex...

OBJECTIVE: To assess whether ice-water immersion or cold-water immersion is the more effective treatment for rapidly cooling hyperthermic runners. DESIGN AND SETTING: 17 heat-acclimated highly trained distance runners (age = 28 +/- 2 years, height = 180 +/- 2 cm, weight = 68.5 +/- 2.1 kg, body fat = 11.2 +/- 1.3%, training volume = 89 +/- 10 km/wk) completed a hilly trail run (approximately 19 ...
متن کاملComparison of the effects of electrical stimulation and cold-water immersion on muscle soreness after resistance exercise.
CONTEXT Resistance training is a common form of exercise for competitive and recreational athletes. Enhancing recovery from resistance training may improve the muscle-remodeling processes, stimulating a faster return to peak performance. OBJECTIVE To examine the effects of 2 different recovery modalities, neuromuscular electrical stimulation (NMES) and cold-water immersion (CWI), on performan...
متن کاملEffect of a 5-min cold-water immersion recovery on exercise performance in the heat.
BACKGROUND This study examined the effect of a 5-min cold-water immersion (14 degrees C) recovery intervention on repeated cycling performance in the heat. METHODS 10 male cyclists performed two bouts of a 25-min constant-paced (254 (22) W) cycling session followed by a 4-km time trial in hot conditions (35 degrees C, 40% relative humidity). The two bouts were separated by either 15 min of se...
