Physical performance differences between weight-trained sprinters and weight trainers

The present study tested and compared well-trained athletes who were performing low-velocity, high-force resistance training and sprint running training (ST) when recruited, with subjects who were performing low-velocity, high-force resistance training but not sprint training (NST) when recruited. Eleven male sprint runners (mean ± SD; age = 19.0 ± 1.4 yr: height = 182.0 ± 4.7 cm: mass = 75.7 ± 4.7 kg), and eight male weight-trained athletes who were not currently performing sprint training, or any other additional training, (mean + SD; age = 21.5 ± 1.8 yr: height = 184.5 ± 3.6 cm: mass = 78.4 ± 4.6 kg) participated in the study; all subjects had a minimum of two years resistance training experience. Tests included 1. running speed (20 m time after a 50 m acceleration distance and 20 m acceleration time from a stationary start), 2. isokinetic hip flexor/extensor torque (and torque adjusted for body mass), angle of peak torque, time to reach peak torque and torque acceleration energy at low (1.05 rad.s−1 [60°.s−1]), moderate (4.74 rad.s−1 [270°.s−1]) and high (8.42 rad.s−1 [480°.s−1]) speeds and 3. maximum squat lift. ST subjects produced more isokinetic hip extensor torque when adjusted for body mass at 4.74 rad.s−1 (270°.s−1;
