The Effect Of Fatigue On Lower Extremity Joint Kinematics And Performance, Sarah Alloto

Undergraduate Distinction Papers

Within recent years there has been an increase in the number of anterior cruciate ligament (ACL) injuries within female athletes (Learning how ACL, 2022). The ACL is a ligamentous structure within the knee that connects the femur and the tibia (Mayo, 2022). Its primary function is to provide stability, prevent the tibia from excessive anterior translation, and provide proprioceptive input for the lower limb (Mayo, 2022). ACL injuries are multifactorial in nature, meaning they can be the result of faulty biomechanics, individual genetic predisposition, or environmental factors (Alentorn- Geli et al., 2009). ACL injuries can be classified into two categories: …

Sled-Pull Training Protocol Increases Critical Speed In Female Collegiate Soccer Players, Andrew J. Hartz, John A. Brasher, Jenevieve L. Roper, Robert V. Musci

International Journal of Exercise Science: Conference Proceedings

Critical speed (CS) is the speed one can sustain while maintaining blood lactate, phosphocreatine, and oxygen uptake levels. “Distance capacity beyond CS” (D’) is the reserve an athlete can draw from to run faster than their CS. By increasing CS and D’, athletes can sustain a faster threshold pace (CS) and have a greater sprint capacity (D’). Unlike distance traveled and speed, which do not reflect the metabolic strain of an exercise, CS and D’ assess the relative intensity of an activity to provide individualized inter- and intra-competition insight. PURPOSE: This investigation evaluated CS and D’ among men and women …

Livestock Performance In Response To High Intensity Rotational Grazing System, Austin Kennedy

Honors Theses

The production of livestock is composed of a variety of factors all effecting the outcome. For grazing livestock, a key factor in production is the grazing management system. Two of the most common grazing management systems are continuous grazing and rotational grazing. There has been evidence found proving benefits of rotational grazing in regard to vegetation productivity, and prevention and restoration of degraded rangeland. However, there is a lack of clear evidence on the relationship between grazing system and production metrics of livestock. Understanding this relationship can provide the necessary information for livestock producers in order to increase their production …

Effect Of Treadmill Surface Stiffness On The Running Economy Benefits Of A Highly-Cushioned Racing Shoe: A Pilot Study, Zane A. Thornton, Dustin P. Joubert

International Journal of Exercise Science: Conference Proceedings

Running economy (RE) is defined as the oxygen consumption (VO₂) at a given running speed. The Nike Vaporfly line of racing shoes, which includes more compliant and resilient midsole foam and a carbon-fiber plate, have been shown to improve RE during treadmill testing. Previous research suggests that RE in general is worse on treadmills with stiffer running platforms. However, it is unclear if the magnitude of the RE benefits provided by these new shoes relative to a control shoe differ based on treadmill stiffness. Given that some treadmill platforms allow more flex or compliance, this may be an …

Animals In Drama And Theatrical Performance: Anthropocentric Emotionalism, Peta Tait

Animal Studies Journal

This article outlines how nonhuman animals are framed by the emotions of drama, theatre and contemporary performance and considers a distinctive tradition in western culture of enacting animal characters who function as surrogate humans. It argues that, contradictorily, while animal characters confirm anthropocentric emotionalism, drama also contains pro-animal values and concern for animal welfare. Animals embodying emotions in theatrical languages are part of the way animals are used in the traditions of western culture and to think and philosophize with, but they also indicate thinking about the emotions in theatrical performance. The article considers if, however, staging living animals can …
