Implementing Eccentric Resistance Training—Part 2: Practical Recommendations, Timothy J. Suchomel, John P. Wagle, Jamie Douglas, Christopher Taber, Melissa Harden, G. Gregory Haff, Michael H. Stone

Exercise Science Faculty Publications

The purpose of this review is to provide strength and conditioning practitioners with recommendations on how best to implement tempo eccentric training (TEMPO), flywheel inertial training (FIT), accentuated eccentric loading (AEL), and plyometric training (PT) into resistance training programs that seek to improve an athlete’s hypertrophy, strength, and power output. Based on the existing literature, TEMPO may be best implemented with weaker athletes to benefit positional strength and hypertrophy due to the time under tension. FIT may provide an effective hypertrophy, strength, and power stimulus for untrained and weaker individuals; however, stronger individuals may not receive the same eccentric (ECC) …

Relationship Between One Repetition Maximum Parallel Squat And Jump Squat Peak Power, Corey Klitzke

Masters Theses

Jump squats are a simple exercise that can be used to train lower body power. Unlike many other methods of power training, jump squats do not require any specialized equipment (platforms, bumper plates, etc.). Jump squats can be used when other forms of power training are not available or are not allowed. In order to most efficiently train power, the intensity must balance force and velocity. The purpose of this study was to find the intensity that yields the peak power output of a jump squat. 12 participants (9 males, 3 female) participated in the study. Each participant completed a …

Kinetic And Kinematic Characteristics Of Accentuated Eccentric Loading, John Wagle

Electronic Theses and Dissertations

The current investigation was an examination of the kinetic and kinematic characteristics of the back squat using accentuated eccentric loading (AEL) and cluster set programming strategies. Trained male subjects (age = 26.1 ± 4.1 years, height = 183.5 ± 4.3 cm, body mass = 92.5 ± 10.5 kg, back squat to body mass ratio = 1.8 ± 0.3) volunteered to complete four different load condition sessions involving traditionally loaded straight sets (TL), traditionally loaded cluster sets (TLC), AEL cluster sets (AEC), and AEL straight sets where only the first repetition of each set used eccentric overload (AEL1). The use of …

The Impact Of Power Training On Balance And Visual Feedback Removal, Juliana Bouton

Senior Honors Theses

Because power training has been known to augment stability, the purpose of this study was to assess whether the removal of visual input affects lower limb muscle power production in young women who are resistance trained to the same degree it affects the untrained. This provided insight as far as the need for resistance training protocols in a largely untrained visually impaired population. To study this, fourteen college-aged female participants (18-23 years) performed a seated double-leg press on a leg sled machine, isolating power production of the lower limbs. After establishing baselines, which involved finding an average of power produced …

Common Habits, Adverse Events, And Opinions Regarding Pre-Workout Supplement Use Among Regular Consumers, Andrew R. Jagim, Clayton L. Camic, Patrick S. Harty

Faculty Scholarship

The purpose of the present study was to examine characteristics of multi-ingredient pre-workout supplement (MIPS) users, their common patterns/habits of MIPS ingestion, and their associated feelings about the effectiveness and safety of this class of supplements. An online electronic survey was distributed through social media to assess self-reported supplementation practices and preferences among adult males and females who reported regular MIPS use. A total of 1045 individuals responded, with 872 of these individuals (males: n = 636, 72.9%; females: n = 233, 26.7%; mean ± SD; age = 27.7 ± 7.9 years; training age = 8.2 ± 7.3 years) completing …

State Population Influences Athletic Performance Combine Test Scores In High School-Aged American Football Players, Zachary M. Gillen, Marni E. Shoemaker, Brianna D. Mckay, Joel T. Cramer

International Journal of Exercise Science

International Journal of Exercise Science 12(6): 256-262, 2019. This study compared athletic performance differences among high school American football combine participants originating from states of different population sizes. High school-aged American football players (n=7,214) who had participated in athletic performance combines between March 2015 and January 2016 were included in this analysis. Data included combine date and location, school state of origin, football position, class, height, weight, 10-, 20-, and 40-yd dash times, pro-agility, L-cone drill, vertical jump, broad jump, and power push-up. Participants were separated into high- (state population>10,000,000; HIGH; n=2,804), mid- (state population=5,000,000-9,999,999; MID; n=2,911), or low-population …

Beyond Peak, A Simple Approach To Assess Rowing Power And The Impact Of Training: A Technical Report, Julian D. Egan-Shuttler, Rohan Edmonds, Cassandra Eddy, Veronica O’Neill, Stephen Ives

International Journal of Exercise Science

International Journal of Exercise Science 12(6): 233-244, 2019. Recently, rowing power has been shown to be a key determinant of rowing performance. However, rowing power testing can vary greatly, and is not standardized. Here we sought to evaluate rowing power over a 15 sec rowing test utilizing a stroke-by-stroke analysis before and after 4 weeks of training in youth rowers. Methods: 18 adolescent male rowers were assigned to complete either 4 weeks of plyometric training (PLYO, n=9), or steady state cycling (Control, n=9), for 30 minutes before on water training three days/week. Each group was matched for training volume. Peak …

Common Ingredient Profiles Of Multi-Ingredient Pre-Workout Supplements, Andrew R. Jagim, Patrick S. Harty, Clayton L, Camic

Faculty Scholarship

Multi-ingredient pre-workout supplements are a popular class of dietary supplements which are purported to improve exercise performance. However, the composition of these products varies substantially between formulations, thus making comparisons challenging. Therefore, the purpose of this study was to identify a common ingredient profile of top-selling pre-workout supplements and to compare ingredient dosages to established efficacious values. The top 100 commercially available pre-workout products were analyzed for listed ingredients and amounts, if available, from the supplement facts panel. The mean ± SD number of ingredients per supplement (n = 100) was 18.4 ± 9.7 with 8.1 ± 9.9 of these …
