Determination of the best recovery based on muscles synergy patterns and lactic acid

The determination of the best recovery after an anaerobic exercise is an important challenge for professional athletes. This study compared and analyzed three methods that are often used in professional teams included: 1.Cold water pool 2. Use the massager 3. Running with 40 to 50 percent of heart rate. Methods: In this work recovery the 15 minutes recovery is done immediately after doing exercise. The impact of a particular method of recovery is quantified via lactic acid in the blood after the recovery and the synergy patterns of muscle activity. In each method, Biceps femoris, rectus femoris, tibialis anterior, lateral gastrocnemius muscles were analyzed. Results showed that there were synergy patterns in two running and ice methods, because maximum errors between basis vectors in all of the subjects were 0.13 and 0.18 respectively and Standard deviation of maximum MSE errors for all subjects is 6 (MSE[1] index), whereas in massage recovery synergy has not been recognized because minimum error between basis vectors in all of the subjects was 4.29 and Standard deviation of maximum MSE error for all subjects is 4. Running has the best result in evacuating lactic acid. However, result in the ice method is similar to running.
