Korelasi Perubahan Nilai Vo2max, Eritrosit, Hemoglobin Dan Hematokrit Setelah Latihan High Intensity Interval Training, Kukuh Pambuka Putra, Muchamad Arif Al Ardha, Angkit Kinasih, Redyte Setio Aji

Jurnal Keolahragaan

Kebugaran kardiorespirasi memungkinkan aktivitas fisik dalam waktu lama dan memerlukan oksigen untuk mendapatkan energi. Transpor oksigen dimediasi oleh hemoglobin yang terdapat dalam eritrosit. Kebugaran kardiorespirasi dapat diukur berdasarkan nilai VO₂max. Metode latihan High Intensity Interval Training (HIIT) terbukti dapat meningkatkan VO₂max. Namun belum jelas apakah peningkatan VO₂max diiringi dan berhubungan dengan perubahan nilai hemoglobin, eritrosit dan hematokrit. Penelitian ini mempelajari korelasi perubahan nilai VO₂max, hemoglobin, eritrosit dan hematokrit sebelum dan sesudah latihan HIIT selama 8 minggu. Berdasarkan hasil penelitian, VO₂max meningkat sebesar 7,33±4,03 (ml·kg^-1·min^-1) atau 20,36% …

Acute Resistance Exercise Induces Sestrin2 Phosphorylation And P62 Dephosphorylation In Human Skeletal Muscle, Nina Zeng, Randall F. D'Souza, Vandre C. Figueiredo, James F. Markworth, Llion A. Roberts, Jonathan M. Peake, Cameron J. Mitchell, David Cameron-Smith

Center for Muscle Biology Faculty Publications

Sestrins (1, 2, 3) are a family of stress-inducible proteins capable of attenuating oxidative stress, regulating metabolism, and stimulating autophagy. Sequestosome1 (p62) is also a stress-inducible multifunctional protein acting as a signaling hub for oxidative stress and selective autophagy. It is unclear whether Sestrin and p62^Ser403 are regulated acutely or chronically by resistance exercise (RE) or training (RT) in human skeletal muscle. Therefore, the acute and chronic effects of RE on Sestrin and p62 in human skeletal muscle were examined through two studies. In Study 1, nine active men (22.1 ± 2.2 years) performed a bout of single-leg strength …

Response Of Appetite And Appetite Regulating Hormones To Acute Hypoxia, Morgan Busboom, Robert Shute, Dustin Slivka

Journal of Human Performance in Extreme Environments

AIM: To determine the acute response of appetite and appetite regulating hormones after exposure to simulated altitude. METHODS: Seven males and five females (height: 178.9 ± 2.3 cm; weight: 77.3 ± 7.2 kg; body fat: 18.4 ± 1.7%) participated in two, three-hour trials in a hypoxic (5000 m) and normoxic (350 m) environment. Blood samples were collected prior to and immediately following three hours of exposure for the measurement of leptin, adiponectin, and acylated ghrelin. Appetite, acute mountain sickness, heart rate, blood oxygenation, tissue oxygenation, respiration rate, and whole body gases were also measured. RESULTS: Leptin was not different between …

Accurate Determination And Application Of Local Strain For Studying Tissues With Gradients In Mechanical Properties, John Boyle

McKelvey School of Engineering Graduate Student Theses & Dissertations

Determination of the mechanical behavior of materials requires an understanding of deformation during loading. While this is traditionally accomplished in engineering by examining a force displacement curve for a whole sample, these techniques implicitly ignore local geometric complexities and local material inhomogeneities commonly found in biologic tissues. Techniques such as normalized cross correlation have been classically applied to address this issue and resolve deformation at the local level; however, these techniques have proven unreliable when deformations become large, if the sample undergoes a rotation, and/or if strain fields become incompatible (e.g. at or near failure).

Presented here is a toolbox …

Mechanics Of The Developing Brain: From Smooth-Walled Tube To The Folded Cortex, Kara Ellspermann Garcia

McKelvey School of Engineering Graduate Student Theses & Dissertations

Over the course of human development, the brain undergoes dramatic physical changes to achieve its final, convoluted shape. However, the forces underlying every cinch, bulge, and fold remain poorly understood. This doctoral research focuses on the mechanical processes responsible for early (embryonic) and late (preterm) brain development.

First, we examine early brain development in the chicken embryo, which is similar to human at these stages. Research has primarily focused on molecular signals to describe morphogenesis, but mechanical analysis can also provide important insights. Using a combination of experiments and finite element modeling, we find that actomyosin contraction is responsible for …

Characterizing Anisotropy In Fibrous Soft Materials By Mr Elastography Of Slow And Fast Shear Waves, John Larson Schmidt

McKelvey School of Engineering Graduate Student Theses & Dissertations

The general objective of this work was to develop experimental methods based on magnetic resonance elastography (MRE) to characterize fibrous soft materials. Mathematical models of tissue biomechanics capable of predicting injury, such as traumatic brain injury (TBI), are of great interest and potential. However, the accuracy of predictions from such models depends on accuracy of the underlying material parameters. This dissertation describes work toward three aims. First, experimental methods were designed to characterize fibrous materials based on a transversely isotropic material model. Second, these methods are applied to characterize the anisotropic properties of white matter brain tissue ex vivo. Third, …

Reduced Vertical Displacement Of The Center Of Mass Is Not Accompanied By Reduced Oxygen Uptake During Walking, Shane R. Wurdeman, Peter C. Raffalt, Nicholas Stergiou

Journal Articles

The six determinants of gait proposed that the goal of gait is to minimize vertical displacement of the body’s center of mass (CoM) with the objective to optimize energy expenditure. On the contrary, recent investigations suggest that reduced vertical displacement leads to an increase in energy expenditure. However, these investigations had the included subjects deliberately changing their gait, which could bias the endpoint measures. The present study investigated the effect of reduced vertical displacement of the CoM on oxygen uptake and walking economy without imposing altered gait patterns. This was accomplished by having subjects walk on a curved treadmill and …

A Motivational Climate Intervention And Exercise-Related Outcomes: A Longitudinal Perspective, Theresa C. Brown, Mary D. Fry, E. Whitney Moore

Kinesiology, Health and Sport Studies

While researchers have suggested that the social context in exercise settings is linked to individuals’ physical activity motivation and potential exercise-related outcomes, few research designs have examined the nuance of those relationships. Moreover, interventions targeting the social context of exercise settings are sparse, so the potential impact of staff training on members’ motivation to exercise are not well known. Drawing from two major motivation theories, achievement goal perspective theory and self-determination theory, this study considered an intervention with fitness center staff from the members’ perspectives. Members completed a survey before and after an intervention designed to help staff create a …

Sport Experiences Of Division I Collegiate Athletes And Their Perceptions Of The Importance Of Specialization, Eric M. Martin, Martha E. Ewing, Evelyn Oregon

Kinesiology Faculty Publications and Presentations

The purpose of the current study was to investigate Division I athletes’ prior sport participation and athletes’ perceptions regarding sport specialization. Athletes (N = 1041) completed self-report surveys and indicated that participation in their collegiate sport began around nine years of age (M = 9.10, SD = 3.83). Athletes played a large number of sports in elementary and middle school with participation decreasing during high school. For those athletes who specialized in one sport, specialization occurred typically at 12.5 years of age. In addition, athletes past sport background and perceptions of specialization differed depending on their college sport with …

Testing Vert™ Accelerometer To Identify Validity And Reliability When Compared To Switch Mat, Tara Mcdonald

Undergraduate Honors Theses
