Using Maximum Power As A Variable For 1rm Prediction In The Squat And Bench Press, Sean O'Connor

Electronic Theses and Dissertations

Many Strength and Conditioning (S&C) coaches utilize a one-rep max (1RM) exercise test to gauge the maximal strength of athletes, and then prescribe resistance training programs based on a relative percentage of 1RM to obtain strength or power adaptations. However, many S&C coaches have raised questions regarding the safety and necessity of a 1RM test. Attempts to mitigate the weaknesses of 1RM testing have led to other methods of testing including repetition max testing (3RM, 5RM, 10RM, etc.) as well as load/velocity profiling. The main purpose of this study is to determine if 1RM can be accurately estimated from maximal …

Ischemic Preconditioning Improves Maximal Accumulated Oxygen Deficit In Ncaa Division I Middle-Distance Runners, Emily Paull

Electronic Theses and Dissertations

Purpose: There is an ongoing debate concerning whether ischemic preconditioning elicits consistent and meaningful exercise performance benefits. We have previously demonstrated no performance benefits of ischemic preconditioning at submaximal aerobic exercise intensities. It is likely that the beneficial effects of ischemic preconditioning on performance only involve supramaximal anaerobic exercise bouts, which elicit greater metabolic and neuromuscular stress. The aim of the study was to test the hypothesis that ischemic preconditioning improves maximal accumulated oxygen deficit (aO2D), an indicator of anaerobic capacity, in NCAA Division I middle-distance runners. Methods: A randomized sham-controlled crossover study was employed in which 10 NCAA Division …

The Effect Of Sport Participation On Bone, Maggie M. Minett

Electronic Theses and Dissertations

Mechanical loading – or physical activity – is essential in the bone remodeling process as well as optimizing the densitometric and geometric properties of bone throughout the lifespan. Participation in sports is a common mode of physical activity that can enhance bone mass accrual at younger ages and facilitate bone mass maintenance at older ages. Research suggests that sport participation continued from adolescence into high school and college provides added benefits on aBMD and cortical bone measures and these benefits remain 10-15 years after retirement from sport. However, in most studies, the higher rates of bone loss after sport cessation …

Differences In Running Mechanics Between Overweight/Obese And Healthy Weight Children, Kristen Roles

Electronic Theses and Dissertations

Background/Purpose: Physical activity is commonly prescribed to reduce childhood obesity. However, due to differences in mechanics during low-impact activities, such as walking, obese children may be more prone to negative physical complications during high-impact activities, such as running. Therefore, this study analyzed the mechanical differences in running mechanics between healthy weight (HW) and overweight/obese (OV/OB) children. We hypothesized that when compared to HW children, OV/OB children would display higher vertical loading, greater joint moments and greater joint angular impulses during running. We also expect decreased sagittal plane range of motion and increased frontal plane range of motion of the hip, …

The Correlation Between Strength Levels Measured Through Dynamic Strength Exercises And The Incidence And Severity Of Injury Among Collegiate Athletes, Alex Jardine
