Deutsch, M. U., Kearney, G. A., & Rehrer, N. J. (1999). The validity of heart rate measurement during intermittent high intensity exercise. Medicine and Science in Sports and Exercise, 31(5), Supplement abstract 404.
Rugby players (N = 20) were monitored for heart rates at 5-second intervals during first grade games. The percent of time spent in four HR zones (>95%, 85-95%, 75-84%, <75%) were calculated. Modes of activity were also concurrently observed.
Significant correlations were found between:
Implication. HR can be used to indicate general classifications of work intensity in rugby football.
