We examined the relationships between change of direction (COD) speed and deficit, and a series of speed-and power-related measurements in national team rugby union players and analyzed the influence of movement patterns on COD ability. Eleven male athletes completed the following physical assessments on different days: day 1—anthropometric measurements, and lower-body kinematic parameters (assessed with eight inertial sensors) and completion time in COD tests (proagility, 45◦ cutting maneuver (CUT), and “L” (L-Drill)); day 2—bilateral and unilateral squat and countermovement jumps, 40 m linear sprint, and bar-power output in the jump squat and half-squat exercises. Pearson’s product–moment correlations were performed to …


Content Analysis Of Patent Applications For Strength Training Equipment Filed In The United States Before 1980, James L. Nuzzo Jan 2021

Content Analysis Of Patent Applications For Strength Training Equipment Filed In The United States Before 1980, James L. Nuzzo

Research outputs 2014 to 2021

Nuzzo, JL. Content analysis of patent applications for strength training equipment filed in the United States before 1980. J Strength Cond Res 35(10): 2952–2962, 2021—Strength training history is an emerging academic area. The aim of the current study was to describe quantitively the history of inventions for strength training equipment. Content analysis was conducted of patent applications for strength training equipment filed with the U.S. Patent and Trademark Office before 1980. Applications were identified using relevant keyword searches in Google Patents. A total of 551 patent applications were analyzed. The earliest application identified was filed in 1860. Applications never exceed …


Cross-Education And Detraining Effects Of Eccentric Vs. Concentric Resistance Training Of The Elbow Flexors, Shigeru Sato, Riku Yoshida, Ryosuke Kiyono, Kaoru Yahata, Koki Yasaka, Kazunori (Ken) Nosaka, Masatoshi Nakamura Jan 2021

Cross-Education And Detraining Effects Of Eccentric Vs. Concentric Resistance Training Of The Elbow Flexors, Shigeru Sato, Riku Yoshida, Ryosuke Kiyono, Kaoru Yahata, Koki Yasaka, Kazunori (Ken) Nosaka, Masatoshi Nakamura

Research outputs 2014 to 2021

Background: Unilateral resistance training increases the strength of the contralateral non-trained homologous muscles known as the cross-education effect. We tested the hypothesis that unilateral eccentric resistance training (ET) would induce greater and longer-lasting cross-education effect when compared with concentric resistance training (CT). Methods: Young (20–23 y) participants were allocated to ET (5 males, 4 females) or CT (5 males, 4 females) group that performed unilateral progressive ET or CT of the elbow flexors, twice a week for 5 weeks (10 sessions) followed by a 5-week detraining, and control group (7 males, 6 females) that did not perform any training. Maximum …

Purpose This study aimed to analyze the effect of resistance training (RT) performed until volitional failure with low, moderate, and high loads on muscle hypertrophy and muscle strength in healthy adults and to assess the possible participant-, design-, and training-related covariates that may affect the adaptations. Methods Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, MEDLINE, CINAHL, EMBASE, SPORTDiscus, and Web of Science databases were searched. Including only studies that performed sets to volitional failure, the effects of low- ( > 15 repetitions maximum (RM)), moderate- (9-15 RM), and high-load ( ≤ 8 RM) RTs were examined in healthy …
