Frederiks, J., Swenne, C. A., Bruschke, A. V., Van Der Velde, E. T., Maan, A. C., Tenvoorde, B. J., Vanrooijen, M G., Mosterd, W. L., & Schiereck, P. (2000). Correlated neurocardiologic fitness changes in athletes interrupting training. Medicine and Science in Sports and Exercise, 32, 571-575.
Dutch male marathon skaters (N = 9) interrupted their training schedules for one month. Baroreflex and cardiac factors were measured at days 0, 4, 7, 14, and 28.
There was a significant decrease in maximal oxygen uptake, a modest, but nonsignificant, increase in resting heart rate, and a decrease in baroreflex sensitivity.
Implication. One month of training cessation will result in considerable decline in aerobic capacity and performance potential in trained marathon athletes.
