"The Distance Traversed by College and High School Basketball Players and Effect of Rule Changes upon Distance Traversed in Gollege Ganes, Paul J. Fay Departnent of Psychology Lioyd L. Messersnith 3 Department of Physical Education DePauy University, Greencastle, Indiana. "In an attempt to determine the effects of the ton second rule and the rule elininating the center jump, as regards the distance traveled by college basketball plavers, the following data wore obtained. This is the continuation of a similar project reported on in 1931, before the inclusion of the ten second rule and the rule elininating the center jump after the scoring of field soalstData are also available on the distance traveled by players in high school basketball games, but no comparison can be made relative to the effect of the two rules in question as no study wags made on high school players before the incorporation of these changes into the official miles. | "The measurenent was made possible through the development of an clectrical pursuit avparatus which provides for numerical registration of unit distance traveled. The piece 1. Mcssorsmith, L. L. Corey, M.S. Distance Traversed oy a Basket»all Player, Research Quarterly, American Physical Education Association, 1931. of apparatus consists of a tin base, on which is etched a basketball court laid off to scale, wired in serics with a storase battery, an clectric impulse countor, and a small brass tracing wheel four inches in diameter. Strips of insulating tape are placed on the wheel at half-inch intervals so that roll- ing it alonz the floor mekes and breaks a circuit each half inch. The impulse counter records these contacts, each one of which, with the calibration employed, indicates a distance of tio fect on the playing floor. To determine the number of fect traveled by a player the experinenter follows the novenents of the player on the small floor with the tracing wheel. Rolling the wheel from one ond of the floor to the other produces a total of 47 contacts, which multiplicd by 2 gives 94 (the length of the college floor in feet)., so any inaccuracy in the result lies in the inability of the opcrator to folllw accurately the movements of the player. When checking hizh school games the small floor is decreased pro- portionately in size to conform with actual measurements of floors where players are being observed. All observations were made from a position above the floor where a clear and unobstructed view of the playing floor was available at all times. The apparatus used in the present study is identical with that used in 1931 so that the relative difference in distance traveled by players in college eames in the two experiments should be reasonably accurate, even thouch slight inaccuracies might oe present in recording the number of feet traversed oy a player in any one game. "In 1931 it was found that tho distance traveled by college players ranged from 2.25 miles t7 2.50 miles per game. in the present study, however, the distance traveled have been consist- ently longer, ranging from 3.87 to 5.97 miles per game. Complete records have been kept of several canes out only three representa- tive games are included in Table I.
