Vercruyssen, Max, Christina, Robert W., Muller, Ellen and Grose, Eric M. (1988): Relationship of Strength and Precision in Shooting Activities. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 1294-1298.

“Reported is an experiment which was designed to (1) test the strength-precision relationship of grip and shoulder strength with competitive pistol shooting scores using a nationally ranked collegiate pistol team and (2) determine the effects of a very brief, specifically focused, intense grip and shoulder strength training program (10 min, 3 times per week for 8 weeks) on strength and shooting performance. All members of the Pennsylvania State University Navy ROTC Pistol Team (n=12) were divided into two matched groups according to pre-test shooting scores. Both groups received identical shooting instruction and practice, but the training group participated in an eight-week strength development program while the control group did not. Maximum isometric strength (peak and 4-sec average force) measures were obtained from electronic output of a hand dynamometer and strain gauge (deltoid contraction from a lateral horizontal shooting position against an arm cuff). Shooting scores (slow fire, timed fire, rapid fire, and total) were used as performance measures.”
