Acute Effects Of Complex Training Using Three Different Intracomplex Rest Intervals On Power Output In Recreationally Trained College Students, Brianna M. Donnelly
West Chester University Master’s Theses
Power is often referred to as explosiveness and is viewed as essential for many athletes within a wide range of sports. Power in sports is important in relation to its foundation in other specific abilities like first step-quickness, acceleration, and reaching top speeds (Cronin, Hansen, 2005). This research study examines the acute effects of complex training using three different intracomplex rest intervals (ICRI) on power output in recreationally trained college students. The goal of this study was to find the optimal ICRI for complex training (CT) by completing a countermovement jump on a force plate after a 3-RM back squat …
Improving Sprint Performance In Road Cycling: The Forward Standing Sprint Position, Paul Franciscus Johannes Merkes
Improving Sprint Performance In Road Cycling: The Forward Standing Sprint Position, Paul Franciscus Johannes Merkes
Theses: Doctorates and Masters
The majority of road cycling races finish with a sprint and as such sprints are a key determinant of success. Surprisingly, the scientific literature on this specific topic is scarce, with limited to few studies describing the characteristics of road cycling sprinters and the demands of road sprinting. Cyclists’ sprinting velocity, which is mostly influenced by power output and aerodynamic drag (CdA) is critical to performance outcomes. However, to date, there is very limited research specifically examining how to maximise road sprint velocity. Thus, the overall objective of the four studies outlined in this thesis was to manipulate CdA, physiology, …

Assessment Of Balance In Collegiate Cheerleaders: Is Implementing A Balance Training Program A Good Idea?, Caitlin Carroll
Honors Theses
Cheerleading has evolved immensely over the years. Gone are the days of simply shaking pom poms and yelling "GO TEAM!" Flips, twists, and prime athletic ability are what can be seen on the sidelines of any collegiate football or basketball game. Cheerleaders in general are assumed to have an above average level of balance, due to the nature of their training and sport. However, with these new skills comes the increasing risk for injury, and this risk may differ according to a cheerleader's position. As with any sport, cheerleading has specific positions. The cheerleaders that are put into the air …

Practical Precooling Strategies And Cycling Time Trial Performance, Megan L. Ross
Practical Precooling Strategies And Cycling Time Trial Performance, Megan L. Ross
Theses: Doctorates and Masters
Whole-body precooling can improve endurance exercise performance, especially in the heat; however there are logistical considerations that restrict the use of various precooling strategies prior to actual competition. Precooling is proposed to collectively reduce deep skin and body temperature and in effect, increase the heat storage capacity of an athlete, thereby allowing a greater amount of work to be completed prior to attainment of a critical core temperature. While there is a sound theoretical basis for implementing precooling to improve cycling time trial performance in the heat, the practicalities of employing effective precooling strategies in the field warrant further investigation. …
Does Training With Powercranks™ Affect Economy Of Motion, Cycling Efficiency, Oxygen Uptake And Muscle Activation Patterns In Trained Cyclists?, Jack Burns
Theses: Doctorates and Masters
PowerCranks™ are claimed to increase economy of motion and cycling efficiency by reducing the muscular recruitment patterns that contribute to the resistive forces occurring during the recovery phase of the pedal stroke. However, scientific research examining the efficacy of training with PowerCranks™ is lacking. Therefore, the purpose of this study was to determine if five weeks of training with PowerCranks™ improves economy of motion (EOM), gross efficiency (GE), oxygen uptake (V.O2) and muscle activation patterns in trained cyclists. Sixteen trained cyclists were matched and paired into either a PowerCranks™ (PC) or Normal Cranks (NC) training group. Prior to training, all …
