Abstract

The purpose of this study was to determine the effects of physical exertion upon the heart rates and workload levels of five selected male freshman basketball players at Utah State University during actual game competition.

One hour prior to each of the ten home basketball games, two E&M Surface Electrodes were mounted to the chest of the test subject with disposable double-sided adhesive washers. A biotelemetry transmitter, used for sending electrical signals from the player to a biotelemetry receive r and polygraph, was placed in a plastic sack and taped to the beltline of the subjects athletic supporter. The telemetry receiver and polygraph were located behind the Utah State University team bench.

One subject was tested per game and each subject was tested twice throughout the study. The same subject was tested once every fifth home game.

The data was collected with a polygraph, by means of radiotelemetry, and recorded according to mean heart (beats per minute), mean volume of oxygen (liters per minute), and mean workload (kilopondmeters per minute), which were the measurements used for the data in the statistical design. In each of these three categories, consideration and comparisons were made of: (A) offensive play, (B) ball handling, (C) defensive play, (D) defense on the ball, (E) fastbreak, (F) shooting, (G) scoring, and (H) rebounding. Data, concerning mean volume of oxygen and mean workload, were processed according to Astrand's Nomogram. A two way analysis of variance test was applied to the data to determine the significant difference between the variables. Another statistical analysis that was conducted on the data was a Newman Keuls Sequential Range Test for determining the significant difference between the eight different game situations studied throughout this study.

The two way analysis of variance showed that there was a significant difference at the .05 level of confidence in the mean heart rate, mean volume of oxygen, and mean workload levels of the five subjects during the game situations mentioned above. The Newman Keuls Sequential Range Test indicated that a significant difference occurred at the .05 level between the ball handling activities (fastbreak, ball handling, and shooting) and the non-ball handling activities (rebounding, scoring, defense on the ball, defensive play, and offensive play). Also, this test showed that no significant difference occurred at the .05 level within the two groups of activities mentioned above.
