Journal of Applied Biomechanics, 9(2), pp. 143-148.https://hdl.handle.net/10877/5506The rebound accuracy of tennis impacts was studied by measuring the vertical angles of approach and rebound of tennis balls projected in a vertical plane at a clamped racket. Three identical oversized tennis rackets were strung with nylon at 200, 267, and 334 N of tension. Ten impacts were filmed at 200 Hz for each string tension with the ball impacting the strings centrally and 8 cm off-center. A two-way ANOVA revealed significant (p < .01) main effects for string tension, impact location, and the interaction of string tension and impact location. Treatment-Contrast Interactions demonstrated one significant (p < .01) difference: The decrease in rebound accuracy from a string tension of 200 to 334 N was significantly different for central versus off-center impacts.Text6 pages1 file (.pdf)entennisrebound accuracystring tensionHealth and Human PerformanceArticle© 1993 by Human Kinetics Publishers, Inc.https://doi.org/10.1123/jab.9.2.143
