Abstract
The possibility of subjective assessment of fatigue in a static muscle load has been demonstrated. Six subjects performed a static muscle exercise with 25, 35 and 45% of their voluntary maximum force. They quantified their subjective feeling of fatigue by means of an assessment scale. The method of fatigue assessment used in these experiments appears to be very reliable and the discriminatory power is great. Differences in assessment of fatigue between the three imposed loads were already significant after 1 min in the working period; they became more significant during this period. They differed also in the first minute of recovery. This method of fatigue assessment has a greater discriminatory power than recording of heart rate.
