Effects of Cooling on Ankle Muscle Strength, Electromyography, and Gait Ground Reaction Forces

Table 1

The means and standard deviations (mean ± SD) of the three MVC trials as well as the mean EMG amplitude during the three MVC trials and normalized mean of the three median EMG values from the three gait trials are given for the TA and GM muscles before and immediately after cooling (𝑛=16).

	Dorsiflexion (TA muscle)			Plantar flexion (GM muscle)
	Precooling	Postcooling	𝑡-test	Precooling	Postcooling	𝑡-test
MVC (Kg)	23.8±2.7	21.3±2.7	<0.001	30.6±4.5	29.7±3.0	0.221
EMG during MVC (µV)	446.4±218.2	443.4±250.7	0.939	284.8±128.3	705.5±487.7	0.003
Normalized EMG in gait trials (%)	11.3±5.3	13.1±7.3	0.158	13.6±10.3	19.8±11.9	<0.001
