Correlation Between Body Fat Percentage And Maximal Exercise (Vo2max) In Collegiate Female Track Athletes, Jennifer Campos

Kinesiology Student Research - Archive

A VO2max test is used to determine the rate of utilization of oxygen which is a measure of cardiorespiratory endurance and aerobic fitness. A relative VO2max is expressed according to body weight in milliliters of oxygen consumed per kilogram of body weight per minute. The amount of body fat we maintain is dependent on diet, exercise, and heredity. Body fat can be measured by several different methods. Hydrostatic weighing determines body fat percentage through the displacement of water and is considered the gold standard in most Exercise Science Programs.

Comparison Of Body Composition, Aerobic And Anaerobic Fitness In Competitive Level Soccer Players With Regards To Position Played, Samantha Maserang

Kinesiology Student Research - Archive

Body composition can be thought of in several different terms. Body Mass Index (BMI) and body fat percentage (%bf) are the two most popular. The BMI is determined from the height and weight only, but the body fat percentage takes the age and ethnicity into account along with the actual measurement to estimate %bf. Body composition and aerobic and anaerobic fitness among high school age female soccer players has not been studied very extensively. Some studies have been conducted to examine body composition, but did not compare the positions each subject played or include the fitness level.

Lower Extremities Muscle Strength Associated With Early Signs Of Mobility Dependence Among Older Adults Age 65 Years And Older, Moshe Marko

Exercise Science - Dissertations

Background: Loss of muscle strength is evident even in apparently healthy older adults. functionally limited due to an increasing discrepancy between their own physiological capabilities (i.e. physiological impairments) and the challenges set forth by the environment. Functional limitations lead to clinical mobility disability. Clinical mobility disability is associated with physical dependence, poor quality of life, and mortality. Treatment of age-related clinical mobility disability should focus on the prevention of the condition rather than its consequences. Identifying opportunities for early screening and prevention of clinical mobility disability requires a better understanding of the functional loss prior to this medical condition. …

Pharmacological Treatment Of Intermittent Claudication Does Not Have A Significant Effect On Gait Impairments During Claudication Pain, Jenna M. Yentes, Jessie M. Huisinga, Sara A. Myers, Iraklis Pipinos, Jason Johanning, Nikolaos Stergiou

Journal Articles

Peripheral arterial disease (PAD) is a manifestation of atherosclerosis resulting in intermittent claudication (IC) or leg pain during physical activity. Two drugs (cilostazol and pentoxifylline) are approved for treatment of IC. Our previous work has reported no significant differences in gait biomechanics before and after drug interventions when PAD patients walked without pain. However, it is possible that the drugs are more efficacious during gait with pain. Our aim was to use advanced biomechanical analysis to evaluate the effectiveness of these drugs while walking with pain. Initial and absolute claudication distances, joint kinematics, torques, powers, and gait velocity during the …

Sensitivity Of The Wolf’S And Rostein’S Algorithms To Evaluate Local Dynamic Stability From Small Gait Data Sets, Fabien Cignetti, Leslie M. Decker, Nikolaos Stergiou

Journal Articles

The Wolf’s (W-algorithm) and Rosenstein’s (R-algorithm) algorithms have been used to quantify local dynamic stability (largest Lyapunov exponent, λ ₁) in gait, with prevalence of the latter one that is considered more suitable for small data sets. However, such a claim has never been investigated. To address it, the λ ₁ of the Lorenz attractor was estimated using small data sets and varied delays and embedding dimensions. Overall, the λ ₁ estimates from the R-algorithm got closer to the theoretical exponent than those from the W-algorithm. The W-algorithm also overestimated λ _{1 …}
