Measuring fatigue

Abstract

8 SS 19-23 YR. OLD PERFORMED AN EXERCISE DURING 11 MIN. ON A BICYCLE ERGOMETER ON 13 DAYS IN SUCCESSION. NOT BEING AWARE OF THE SYSTEMATIC DAILY VARIATIONS IN THE SLOPE OF THE WORK LOAD, ALL SS SHOWED SIGNIFICANT CORRELATIONS BETWEEN SUBJECTIVE FEELINGS OF GENERAL PHYSICAL FATIGUE-AS EXPRESSED ON DIFFERENT KINDS OF RATING SCALES-AND SLOPE OF WORK LOAD. REGRESSION EQUATIONS SATISFACTORILY DESCRIBE LINEAR RELATIONSHIPS BETWEEN LOAD AND FATIGUE. FACTOR ANALYSIS SUGGESTS A FACTOR "INCREASING FATIGUE," AND A FACTOR "DECREASING FITNESS."
