The effect of physical effort and training unit is The effect of high,intensity physical exertion in hot climates on some functional indicators of the heart and blood circulation during the training unit for basketball players

Abstract

The aim of the current research is to determine the effect of physical effort and a training session in hot climates on some functional variables of the heart in basketball players, by detecting some changes in systolic pressure (S.P.), dias-tolic pressure (D.P.), and stroke. Volume (S.V.), pulse rate (HR), and cardiac output (C.O.P.) are considered important functional indicators that reflect the extent of the health of the heart's functions and thus the extent to which the exerted effort matches the functional capacity of the heart. The researcher used the experimental method, and the research was conducted on a purposive sam-ple of (7) basketball players. At Al,Sawaqi Sports Club, pre,tests and meas-urements were conducted for some functional variables of the heart in basket-ball players. The same measurements and tests were also performed after the training unit and under the same preconditions. The results showed that there were statistically significant differences between the results of the pre, and post,tests, in favor of the pre,tests in all indicators. The study showed an in-crease in functional indicators of the heart, systolic pressure (S.P.), diastolic pressure (D.P.), pulse rate (HR), stroke volume (S.V.), and cardiac output (C.O.P.) in the body. The researcher recommends the necessity of emphasizing the conduct of training units in an atmosphere similar to that of matches to create the required adaptations .
