Use Of Counter-Balanced Smith Machine Affects Performance Measurements For Rebound Bench Press Throws, Harsh Buddhadev, Anthony A. Duplanty, David W. Hill, Simon Driver, Noreen L. Goggin, Jakob L. Vingren Feb 2011

Use Of Counter-Balanced Smith Machine Affects Performance Measurements For Rebound Bench Press Throws, Harsh Buddhadev, Anthony A. Duplanty, David W. Hill, Simon Driver, Noreen L. Goggin, Jakob L. Vingren

International Journal of Exercise Science: Conference Proceedings

Rebound bench presses throws (RBT), often performed on a Smith machine, are used for assessment and training of upper body power. During a RBT, the stretch-shortening cycle potentiates performance in the concentric movement. Smith machines frequently utilize a counter-balance weight to reduce the net load on the barbell; however, the use of counter-balance weight affects measures of performance for RBT. PURPOSE: To evaluate how the use of a counter-balanced Smith machine affects performance measures for RBT. METHODS: Performance measures for the no counter-balanced (NCB) and counter-balanced (CB) RBT were assessed for 24 men (age: 23 ± 3 years, height: 179 …


Effect Of Using A Counter-Balanced Smith Machine On Performance Measurements For Concentric-Only Bench Press Throws, Anthony A. Duplanty, Harsh Buddhadev, David W. Hill, Simon Driver, Noreen Goggin, Jakob Vingren Feb 2011

Effect Of Using A Counter-Balanced Smith Machine On Performance Measurements For Concentric-Only Bench Press Throws, Anthony A. Duplanty, Harsh Buddhadev, David W. Hill, Simon Driver, Noreen Goggin, Jakob Vingren

International Journal of Exercise Science: Conference Proceedings

Bench press throws using a Smith machine are often used for assessment and training of upper body power. Concentric only bench press throws (CON-BT) provide important information on an individual’s ability to produce force from a static start. Smith machines often utilize a counter-balance weight system to reduce the net load on the barbell; however, it is not known how counter-balance weight affects measurements of performance during a CON-BT. PURPOSE: To examine the effect of a counter-balance weight on CON-BT performance measurements. METHODS: 24 men (age: 23 ± 3 years, height: 179 ± 6 cm, mass: 91 ± 17 kg, …
