Conclusions
twitch, fatigue
In summary, 3 weeks of mental training modifies central motor command as evidenced by a decrease in rectus femoris EMG. This reduction produced lower ventilation, oxygen consumption, and rate of fatigue accumulation as measured by potentiated twitch. These physiological changes led to a 10% increase in performance in a cycling time to exhaustion test and prevented a decrease in performance as seen in the control group. Further study is necessary to determine what exact changes are occurring within the brain and to verify the physiological and psychological improvements following mental training.
