Purpose: To establish rates of shoulder pain, regardless of whether it resulted in a loss of playing time, in female high school volleyball players. A secondary goal was to determine whether high repetition volumes correlated …

Are Preseason Functional And Biomechanical Measures Associated With Lower Quadrant Injury Risk In Division Iii Athletes?, Natalie Ellis, Jordan Petersen, Jordon Reyes, Victor Wilson, Cj Zita

Student-Faculty Research - College of Physical Therapy

A recent trend in sports medicine research is to determine risk of injury during sport based on preseason functional performance test (FPT) measures.

Equivocal findings associated with prior studies may leave PTs with uncertainty as to which FPT, or combination of FPTs, can best identify athletes who have a greater risk for injury.

Previous studies have utilized "low-tech" FPT measures: standing long jump (SLJ), single-leg hop (SLH), lower extremity functional test (LEFT), and the Y-balance test (YBT) (1,3,4).

These "low-tech" options may not be able to identify potential deficits that could be collected with "high-tech" measures (e.g., DVJ measures collected …

The Effect Of One-On-One Intervention In Athletes With Multiple Risk Factors For Injury, Kathryn Schwartzkopf-Phifer

Theses and Dissertations--Rehabilitation Sciences

Background: Lower extremity (LE) musculoskeletal injuries in soccer players are extremely common. These injuries can result in many days of lost time in competition, severely impacting players and their respective teams. Implementation of group injury prevention programs has gained popularity due to time and cost-effectiveness. Though participation in group injury prevention programs has been successful at reducing injuries, programs often target a single injury and all players do not benefit from participation. Players with a greater number of risk factors are most likely to sustain an injury, and unfortunately, less likely to benefit from a group injury prevention program. …

The Physiological Effects Of A Cross Country Bike Ride On Novice Cyclists, Wade Weatherholt

Mahurin Honors College Capstone Experience/Thesis Projects

Purpose: The physiological responses and adaptations experienced by novices engaging in cross-country cycling have received little attention in the scientific literature. Such endeavors typically involve a sizeable increase in physical activity for most individuals, but the acute and chronic effects of such an endurance feat are not well understood. Similarly, research shows that experienced cyclists often demonstrate osteoporosis in the spine, linked to many years of training accompanied by little or no weight bearing stress upon the axial skeleton. Greater understanding of these issues is needed, as long distance cycling has increased in popularity in recent years, and exercise professionals …

Acl Injuries In Female Athletes, Leslie A. Mesa

Scholarly and Creative Works Conference (2015 - 2021)

The Anterior Cruciate Ligament has been studied in many different ways and become injured more with the increase in sports participation by both male and female athletes. “ACL injuries are 9x more common in female athletes than male athletes and over 1.4 million women have been suffered from the ACL rupture which is twice the rate of the previous decade” (Hewett, 2010). ACL injuries are known to occur more in females than males because of differences in anatomy, knee alignment, muscle strength, and conditioning. Since female athletes are more prone to injury, it is important to incorporate neuromuscular training to …

A Difference In Aerobic And Anaerobic Energy Costs During Weightlifting, Sarah Shapiro, Deline Dwelly

Thinking Matters Symposium Archive

Energy expenditure is usually estimated by total oxygen uptake. However, with weightlifting, very little oxygen is utilized during the lift. The majority of oxygen uptake happens during recovery (Excess Post-Exercise Oxygen Consumption, EPOC). The purpose of this study is to determine the significance of the anaerobic and EPOC phases during weightlifting exercises in estimation of total energy cost. We gathered data from 42 subjects (60 averaged trials) aging between 18 and 35 years. Each subject chose a comfortable weight and lifted to a cadence of 1.5 sec up and 1.5 sec down. Tests were given on two different occasions. We …
