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) …
The Influence Of Strength In Load-Velocity Relationships In The Back Squat, Thaddeus Light
The Influence Of Strength In Load-Velocity Relationships In The Back Squat, Thaddeus Light
Electronic Theses and Dissertations
Load-velocity relationships may vary between people of different strength levels and across different loads. The purpose of this dissertation was to investigate how external loads influence the velocity characteristics of the back squat exercise, and the influence of strength on these variables. Healthy male students with a history of resistance training completed repetitions at specified intensities of their estimated one-repetition maximum (1RM) until they reached 1RM. Back squat 3D motion analysis was captured using four Vicon T010 cameras (Vicon Motion Systems Ltd.; Oxford, UK) and Vicon Nexus 1.8.5 software. Data were transported into R custom coding statistical analysis software (version …

The purpose of the study was to compare the physiological responses of skeletal muscle to a resistance training (RT) program using repetition maximum (RM) or relative intensity (RISR). Fifteen well-trained males underwent RT 3 d·wk−1 for 10 weeks in either an RM group (n = 8) or RISR group (n = 7). The RM group achieved a relative maximum each day, while the RISR group trained based on percentages. The RM group exercised until muscular failure on each exercise, while the RISR group did not reach muscular failure throughout the intervention. Percutaneous needle biopsies of the vastus lateralis were obtained …
Kinetic And Kinematic Characteristics Of Accentuated Eccentric Loading, John Wagle
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 …
Effects Of Resistance Training Frequency On Muscle Function Adaptations Using A Multiple-Joint Eccentric Training Model, Joshua Crane
Effects Of Resistance Training Frequency On Muscle Function Adaptations Using A Multiple-Joint Eccentric Training Model, Joshua Crane
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Eccentric resistance training has been shown to be beneficial for improving multiple performance and health metrics. However, recommendations on eccentric training frequency have not been established. PURPOSE: To investigate the effects of volume-matched resistance training frequency comparing one versus three training days per week of isokinetic multiple-joint eccentric training on strength and lower body function adaptations during a 4-week training period. METHODS: Thirty recreationally-trained men and women were randomly assigned to either a high frequency (HF), three times per week, or low frequency (LF), once per week, training group for four weeks. A motor-driven isokinetic eccentric dynamometer was used for …
The Effect Of Exercise Order In Circuit Training On Muscular Strength And Functional Fitness In Older Women, Diogo Correia Cardozo, Belmiro Freitas De Salles, Pietro Mannarino, Ana Paula Sena Vasconcelos, Humberto Miranda, Jeffrey M. Willardson, Roberto Simão
The Effect Of Exercise Order In Circuit Training On Muscular Strength And Functional Fitness In Older Women, Diogo Correia Cardozo, Belmiro Freitas De Salles, Pietro Mannarino, Ana Paula Sena Vasconcelos, Humberto Miranda, Jeffrey M. Willardson, Roberto Simão
International Journal of Exercise Science
International Journal of Exercise Science 12(4): 657-665, 2019.The purpose of this study was to analyze the effect of different orders of exercises in circuit training on strength and functional fitness in older women over a 12-week period. After 10 repetition maximum (10-RM) and functional fitness baseline testing, thirty older women were randomly assigned into two groups. The exercise order for Group 1 was leg press, wide-grip lat pulldown, knee extension, pec deck fly, plantar flexion and triceps extension; Group 2 performed the same exercises, but in the opposite order: triceps extension, plantar flexion, pec deck fly, knee extension, wide-grip …

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 …
Common Ingredient Profiles Of Multi-Ingredient Pre-Workout Supplements, Andrew R. Jagim, Patrick S. Harty, Clayton L, Camic
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 …
An Examination Of The Effects Of Bilateral And Unilateral Very Short-Term Dcer Training On Strength And Neuromuscular Responses Within The Lower Limb Bilateral Deficit, Mark Travis Byrd
Theses and Dissertations--Kinesiology and Health Promotion
The very short-term resistance training (VST) model, utilizing only 2-3 training sessions, has been used to examine early phase skeletal muscle, neural, and performance adaptations. The VST model has previously been used to examine these early phase adaptations in bilateral and unilateral, isometric, isokinetic, and dynamic muscle actions in the limbs of the upper- and lower-body. The bilateral deficit (BLD) is a phenomenon in which the sum of the forces produced unilaterally is greater than the force produced bilaterally during maximal contraction of the limbs. The appearance of a bilateral deficit has been be related to various factors; including training …
