Comparison Of Single Leg Squat Variations On Lower Limb Muscle Activation And Center Of Pressure Alterations, Mary Grace Knoll, Mackenzie C. Davidge, Claire E. Wraspir, John A. Korak

International Journal of Exercise Science

International Journal of Exercise Science 12(1): 950-959, 2019. Following anterior cruciate ligament reconstruction, individuals experience inadequate functioning of the quadriceps and decreased muscular strength. Decreased function delays return to physical activity and increases potential for re-injury. While several squat variations exist, a new variation has emerged in rehabilitation. The purpose of this study was to compare muscle activation of the Vastus Lateralis (VL), Vastus Medialis (VM), Rectus Femoris (RF), Gluteus Maximus (GM), and anterior posterior center of pressure (AP displacement) alterations during a single leg squat variation (SLS variation) versus a traditional split squat using electromyography (EMG) in healthy active …

Effects Of Home-Based Exercise Training Systems, Combined With Diet, On Cardiometabolic Health, Christian K. Roberts, David E. Segovia, Eli Lankford

International Journal of Exercise Science

International Journal of Exercise Science 12(2): 871-885, 2019. The efficacy of exercise training systems designed to be used in the home on cardiometabolic outcomes remains largely unknown. This investigation included two studies. Study 1 tested the effects a multi-exercise pulley system(NordicTrack Fusion CST with video trainer) and Study 2 an incline trainer (NordicTrack X22i with video trainer), both combined with daily food provision, for 12-weeks on indices of cardiometabolic health. Study 1 enrolled 27 adults (11 men, 16 women, 33.8±4.4 years of age) and Study 2 enrolled 29 adults (11 men, 18 women, 40.8±12.5 years of age). Pre- and post-intervention …

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

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 …

Factors Related To Average Concentric Velocity Of Four Barbell Exercises At Various Loads, Christopher A. Fahs, Julia C. Blumkaitis, Lindy M. Rossow

Faculty Scholarship

The resistance exercise load is the primarily determinant of the average concentric velocity (ACV) during a repetition. It is unknown whether individual factors such as training experience or anthropometrics also influence the ACV. Previous research has shown the ACV during the 1 repetition maximum (1RM) varies between exercises, but it is not clear whether ACV is different between exercises at various percentages of the 1RM. This information could provide practical guidelines for trainees using ACV to select training loads. Therefore, the purpose of this study was to determine whether training age, current training frequency, limb length, height, and relative strength …

A Comparison Between The Efficacy Of Traditional Periodization, Undulating Periodization, And Plyometric Training And Their Lasting Effects On Performance Outcomes In Youth Athletes. A Systematic Review And Meta-Analysis, Andre Mcintyre

Electronic Theses and Dissertations

Recreational and competitive youth (≤ 16 years old) sport participation over the years has increased in recent years. As a result of increased sport participation an emphasis on sport performance training and more particularly resistance training along with plyometric training have been on the rise. Resistance training and plyometric training can improve sports performance, rehabilitate injuries, prevent injuries, and enhance long-term health in adolescent athletes. Resistance training can be periodized numerous different ways, but the most popular training methods are traditional periodization, undulating periodization, and plyometric training. This systematic review and meta-analysis examined studies that compared traditional periodization, undulating periodization, …

Mind-Muscle Connection: Effects Of Verbal Instructions On Muscle Activity During Bench Press Exercise, Antonio Paoli, Laura Mancin, Matteo Saoncella, Davide Grigoletto, Francesco Q. Pacelli, Paola Zamparo, Brad J. Schoenfeld, Giuseppe Marcolin

Publications and Research

Different attentional foci may modify muscle activation during exercises. Our aim was to determine if it is possible to selectively activate the pectoralis major or triceps brachii muscles according to specific verbal instructions provided during the bench press exercise. 13 resistance-trained males (25.6±5.4 yrs, 182.7±9.1 cm, 86.4±9.7 kg) underwent an electromyographic signals acquisition of the sternocostal head, clavicular head of the pectoralis major, the anterior deltoid, and the long head of the triceps brachii (LT) during bench press exercise. Participants performed one non-instructed set (NIS) of 4 repetitions at 50% 1-repetition maximum (1-RM) and one NIS of 4 repetitions at …
