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
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
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, …

Effect Of Single Set Dynamic And Static Stretching Exercise On Jump Height In College Age Recreational Athletes, Jeffrey C. Murphy Dr., Elizabeth F. Nagle, Robert J. Robertson Dr., Jean L. Mccrory Dr.
International Journal of Exercise Science
This study examined the effects of single set dynamic and static stretching on vertical jump height and hip and knee range of motion in a sample of college age recreational males. Forty-two males (aged 18-24) healthy, physically active volunteers participated as subjects in this investigation and were randomly assigned to one of three groups (1 set of 20 seconds dynamic stretch, 1 set of 20 second static stretch, or control). The knee and hip range of motion, sit and reach, and jump height were measured before and after the treatment condition. The same measures were performed on the control group …
Multiple Models Can Concurrently Explain Fatigue During Human Performance, C. Matthew Laurent†, Matt Green‡
Multiple Models Can Concurrently Explain Fatigue During Human Performance, C. Matthew Laurent†, Matt Green‡
International Journal of Exercise Science
One of the most commonly and thoroughly studied paradigms of human performance is fatigue. However, despite volumes of research there remains considerable controversy among scientists regarding definitive conclusions about the specific mechanism(s) contributing to fatigue. Within the literature there are three primary yet distinctly different governing ideas of fatigue; the traditionally referenced central model and peripheral model as well as the emerging central governor model (CGM). The CGM has recently been advocated by a limited number of researchers and is suggestive of a more integrative model of fatigue when compared the traditional peripheral and central models. However, more work is …
Timing Carbohydrate Beverage Intake During Prolonged Moderate Intensity Exercise Does Not Affect Cycling Performance, George G. Schweitzer†, John D. Smith‡, James D. Lecheminant‡
Timing Carbohydrate Beverage Intake During Prolonged Moderate Intensity Exercise Does Not Affect Cycling Performance, George G. Schweitzer†, John D. Smith‡, James D. Lecheminant‡
International Journal of Exercise Science
Carbohydrate beverages consumed during long-term exercise have been shown to attenuate fatigue and improve performance; however, the optimal timing of ingestion is unclear. Therefore, the purpose of this study was to determine if timing the carbohydrate ingestion (front-loading (FL), continual loading (CL), and end-loading (EL)) during prolonged exercise influenced exercise performance in competitive cyclists. Ten well-trained cyclists completed three separate exercise bouts on a bicycle ergometer, each lasting 2 hours at an intensity of ~67% VO2 max, followed by a 15-minute “all out” time trial. In the FL trial, participants ingested a carbohydrate beverage during the first hour and …
