Abstract
Using a newly developed telemetry system, records of heart-rate reaction of human subjects prior to the rope climb were obtained. The data presented on humans represents support for research by Rushmer, who experimented with dogs in demonstrating the role of the motor cortex in controlling the heart boat and particularly its involvement prior to vigorous exercise. The data consists of telemetered heart rates of 10 gymnasts prior to, during and following a rope climb for speed. The percentage of anticipatory heart rate increase over basal value of post-warm-up for the climb was approximately 25 per cent. This amount of anticipatory heart rate for the 10 subjects unassociated with actual energy expenditure would permit support of Rushmer's theory.
