أثر الغمر بالماء البارد و الكرياتين الباودر على إشارات تلف العضلة و زمن تحمل الأداء البدني

الملخص EN

The aim of the present study was to examine effects of cold water immersion and creatine powder on signs of muscle damage and time of performance endurance.

Using a random, blind-design, eight athletes participated in all four trials (14 days apart).

Athletes performed a seated leg extension machine 5 sets × 20 rep after 30 minutes rest included either cold water immersion of lower body for 12 minutes (CWI trial), intake of 5g of Creatine powder (Cr trial), (CWI+Cr trial) or control trial.

After that, athletes performed an incremental running protocol until volitional fatigue.

Creatine kinase and myoglobin were significantly (α=0.05) lower in trials of CWI and CWI+Cr.

Aldolase and lactic dehydrogenase were significantly lower in Cr trial.

Time of performance endurance was significantly longer in CWI+Cr trial.

In conclusion, CWI, Cr, and CWI+Cr trials alleviated signs of muscle damage without suppression.
