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 Jun 2019

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 ...


Effects Of Home-Based Exercise Training Systems, Combined With Diet, On Cardiometabolic Health, Christian K. Roberts, David E. Segovia, Eli Lankford May 2019

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 ...


Effects Of Resistance Training Frequency On Muscle Function Adaptations Using A Multiple-Joint Eccentric Training Model, Joshua Crane May 2019

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

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 Impact Of Power Training On Balance And Visual Feedback Removal, Juliana Bouton Apr 2019

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

Juliana Bouton

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 ...


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 Jan 2019

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, plyometric ...
