Abstract
Attention in this review was directed toward recent work on physiological systems and their interactions with sensory responses during positive continuous exercise. Sensation was defined as a central nervous system response of the body as a direct result of stimulation of a sense organ. The effects of exercise on both the circulatory and respiratory systems were noted, along with thermoregulatory changes occurring in the body. Studies have indicated that thermal sensation during exercise is basically subjective, but it arises from various information generated in different parts of the body. What kind of sensation the individual feels depends on the general activity of the central nervous system at the time and on prior experience. Actual discomfort, however, arises whenever physiological mechanisms such as sweating and increase in skin blood flow are activated to bring heat loss into balance with metabolic heat production. The body is also able to adapt to some degree to various external conditions resulting in heat acclimation. The sensory responses to thermal sensation and discomfort are closely tied with associated physiological responses. These are controlled as an outcome of central and peripheral thermal signals. The sensation of effort responds primarily to a peripheral signal related to both force of muscle contraction and rate of muscle contraction and consequent metabolic demand. This sensation of effort brings yet another parameter into play in determining the response of the individual to physical exercise.
