Notes: The best MD value in each row has been indicated in Bold format. **These two rows did not achieve any significant change within the groups; then we did not indicate the maximum amount of improvement among them.
Abbreviations: mm2, millimeter square; ms, millisecond; m/s, meter per second; mV, millivolt; µV, microvolt; kg, kilogram.
