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

Abstract

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 i mpact 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 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.

New Method to Assess and Enhance Athletes’ Performance Based on Muscle Synergy Patterns: A New Approach to Design a Biofeedback Training Scheme

“…The ith dimensional basis vector is called 𝑤 𝑖 . The ith basis vector's scalar activation coefficient is c(t)i (Torbati et al, 2017;Torbati et al, 2018;Torres-Oviedo et al, 2007). In this study, the HALS algorithm was used because this algorithm is fast with high accuracy and robust to noise (Torbati et al, 2017).…”

“…(5) SSE is the sum of the squared residuals, and SST is the sum of the squared residuals from the mean activation vector (m ̅ ) (Torbati et al, 2017;Torbati et al, 2018). Four synergies for leg muscles were used in this investigation because R2 is consistent after four synergies.…”

Pemulihan Suhu Tubuh Dan Denyut Jantung Dengan Metode Sport Massage Dan Stretching Statis Setelah Berenang

“…Walaupun beberapa ahli mengemukakan, bahwa sebaiknya program latihan baik perlu melibatkan program pemulihan yang ideal (Rozi et al, 2018). Sekitar 50% puncak penguasaan keterampilan dan performa berlatih renang sangat dipengaruhi oleh kemampuan pemulihan kelelahan, sehingga untuk mencapai keberhasilan tujuan latihan perlu metode pemulihan yang tepat (Moghaddam et al, 2017).…”
