The Effect Of Lactate Buildup As An Energy Substrate During A Short-Duration, High-Intensity Run Of 400-M And A Medium Run Of 800-M On Uta Kinesiology Students, Davor Krnjajic
Kinesiology Student Research - Archive
Lactic acid is a metabolic byproduct of the anaerobic glycolysis energy system present in blood and muscle. Some research indicates that lactic acid is a marker of fatigue during short duration exercise due to its dissociation into lactate and the H+ ion, whose accumulation in tissues and blood can lead to a subsequent decrement in muscle and plasma pH causing an inhibition of coupling mechanisms and enzymatic processes necessary for maintenance of muscular force production. Other studies have not implicated lactate to be the sole contributor of fatigue, as different types of exercise produce multifaceted fatigue factors, depending on muscle …

The Evaluation Of Hand Strength In An Aging Population, Linzi Ball
Kinesiology Student Research - Archive
Muscular deterioration is a well known effect that aging has on individuals. As a person gets older, their muscles naturally become worn down and more atrophied as compared to their younger counterparts. The ability of an individual to perform their activities of daily living may be compromised by low muscular strength even in healthy older individuals. There is mounting evidence to show not only endurance capacity but also strength is a predictor of health, especially in elderly people. Many studies have shown a correlation between muscular strength and future morbidity, disability, and mortality in these individuals and many of them …

Background: Previous research has demonstrated that trained rescuers have difficulties achieving and maintaining the correct depth and rate of chest compressions during both in and out of hospital cardiopulmonary resuscitation (CPR). Feedback on rate and depth mitigate decline in performance quality but not completely with the residual performance decline attributed to rescuer fatigue. The purpose of this study was to examine the effects of feedback (none, auditory only and visual only) on the quality of CPR and rescuer fatigue. Methods: Fifteen female volunteers performed 10 minutes of 30:2 CPR in each of three feedback conditions: none, auditory only, and visual …

Background: Hands-Only cardiopulmonary resuscitation (CPR) is recommended for use on adult victims of witnessed out-of-hospital (OOH) sudden cardiac arrest or in instances where rescuers cannot perform ventilations while maintaining minimally interrupted quality compressions. Promotion of Hands-Only CPR should improve the incidence of bystander CPR and, subsequently, survival from OOH cardiac arrest; but, little is known about a rescuer's ability to deliver continuous chest compressions of adequate rate and depth for periods typical of emergency services response time. This study evaluated chest compression rate and depth as subjects performed Hands-Only CPR for 10 minutes. For comparison purposes, each also performed chest …

Injury to the anterior cruciate ligament (ACL) has become a global topic of research, as the number of injuries is staggering and continues to increase each year because the underlying elements contributing to this injury have yet to be fully grasped. It is estimated that 80,000 – 250,000 ACL injuries occur annually in female athletics.(45) As a result, an estimated number of 100,000 ACL reconstructions are performed annually.(2) The uncertainty involving the contributing causes of this injury has naturally ushered uncertainty involving the treatment of the injury, i.e. surgical repair and subsequent rehabilitation. Although considerable gains toward improving surgical procedure …

Effects Of Age And Cardiopulmonary Resuscitation (Cpr) Techniques On Characteristics Of Muscle Fatigue In Females Trained In Cpr Administration, Jesal N. Parekh
Effects Of Age And Cardiopulmonary Resuscitation (Cpr) Techniques On Characteristics Of Muscle Fatigue In Females Trained In Cpr Administration, Jesal N. Parekh
Kinesiology Theses - Archive
Cardio pulmonary resuscitation (CPR) is a widely popular and recommended assessment and intervention technique for life threatening conditions resulting from cardio-pulmonary disorders. As per the American Heart Association® 2005 revised guidelines for CPR administration, the rescuer is required to perform chest compressions and ventilations in the ratio of 30:2 at a rate of 100 compressions per minute with minimal interruption to chest compressions. In the process of CPR administration, the rescuer is likely to experience fatigue over time with continual compressions and ventilations. Fatigue is expected to manifest through variations in the rescuer's muscle activity, changes in joint kinetics and …
The Effects Of Pulsed Shortwave Diathermy And Stretch On The Torque-Angle Relation Of The Calf (Plantar Flexor) Muscles Association With Passive Stretch Both During And After Treatment, Megan J. Schorr
Kinesiology Theses - Archive
Our objective was to assess the short-term effects of PSWD and stretch on the torque-angle relation of the calf both during and after PSWD treatment. We used a 3 X 4 and a 2 X 4 (Time X Treatment) crossover repeated measures design. The independent variables were condition (stretching during diathermy, stretching after diathermy, and stretching during and after diathermy treatment) and time (pre, post, 15-minutes post treatment). Sixteen males participated in the study. Dependent variables were energy absorbed, energy returned, peak torque, average stiffness, intramuscular temperature, and average range of motion (ROM). There was a greater increase in tissue …

The Acute Effects Of Active Warm-Up And Passive Warm-Up On Passive Tension, Troyce Solley
Kinesiology Theses - Archive
The purpose of this study was to investigate the effects of active warm-up (stationary cycling) and passive warm-up (heat pack) on the mechanical properties of the hamstring musculature in vivo. Passive tension measurements were recorded during the passive knee extensions of ten men before and after an active warm-up, passive warm-up, and control treatments. The results of the present investigation revealed no effect of active warm-up or passive warm-up on the passive tension variables of energy absorbed, energy returned, peak torque, average stiffness, or peak stiffness of the hamstring musculature. These findings suggest that the mechanical properties of the connective …

Human immunodeficiency virus (HIV)-infected athletes exist at the collegiate level and are engaging in competitive sports, as was revealed by a 1993 NCAA survey. Unfortunately, there is a void when the issue of policy for the HIVpositive athlete and his or her participation rights at the collegiate level is addressed. Given the controversial nature of opinion on HIV and the resultant acquired immunodeficiency syndrome (AIDS), it is recommended that a policy be in place for an HIV-infected athlete before it is needed. Ithaca College has recently developed such a policy, and it is offered here to other educational institutions as …
