Effects Of Whole Body Vibration Training On Body Composition, Skeletal Muscle Strength, And Cardiovascular Health, Song-Young Park, Won-Mok Son, Oh-Sung Kwon

Health and Kinesiology Faculty Publications

Whole body vibration training (WBVT) has been used as a supplement to conventional exercise training such as resistance exercise training to improve skeletal muscle strength, specifically, in rehabilitation field. Recently, this exercise modality has been utilized by cardiovascular studies to examine whether WBVT can be a useful exercise modality to improve cardiovascular health. These studies reported that WBVT has not only beneficial effects on muscular strength but also cardiovascular health in elderly and disease population. However, its mechanism underlying the beneficial effects of WBVT in cardiovascular health has not been well documented. Therefore, this review highlighted the impacts of WBVT …

The Effects Of Aerobic Exercise Training On Blood Lipid Profiles, Fibrinolytic Activities, And Nitric Oxide Levels In High-Fat-Diet Induced Rats, Won-Mok Son, Do-Yeon Kim, Ki-Dong Sung, Yi Sub Kwak, Yeong Ho Baek, Song-Young Park

Health and Kinesiology Faculty Publications

Although exercise training has been utilized to improve vascular function in animals and humans, the impact of moderate intensity exercise training on fibrinolytic activities and nitric oxide (NO) bioavailability has not been well documented. Therefore, the purpose of the current study was to examine the impact of moderate intensity aerobic exercise training on fat mass, blood lipid profiles, fibrinolytic activity, and NO levels in high-fat-diet induced rats. The body weight, fat mass, blood lipid profiles, fibrinolytic activity, and nitrite/nitrate were measured pre- and postexercise (10 weeks) training. The body weight and fat mass reduced significantly in the exercise (EX) group …

The Clinical Evaluation Between Overtraining Syndrome And Exercise-Related Immunity, Song-Young Park, Yi Sub Kwak, Seung-Jun Choi

Health and Kinesiology Faculty Publications

The present study was performed to analyze and review the physical and immune responses to overtraining syndrome in humans. Overreaching refers to the initial phage of overtraining syndrome and has been known as a physical fatigue which is mainly from metabolic imbalance. It has been known that overtraining also results in a loss of adaptability which may lead to an attenuation of exercise performance, sleeping disorder, central fatigue, neurohormonal changes, difficulty recovery to physical stress, and immunological changes. Additionally, overtraining syndrome is characterized by persistent fatigue, poor performance in sport due to the prolonged and strenuous physical training. Also, previous …

Quadriceps Exercise Intolerance In Patients With Chronic Obstructive Pulmonary Disease: The Potential Role Of Altered Skeletal Muscle Mitochondrial Respiration, J. R. Gifford, Joel D. Trinity, Gwenael Layec, Ryan S. Garten, Song-Young Park, Matthew J. Rossman, Steen Larsen, Flemming Dela, Russell S. Richardson

Health and Kinesiology Faculty Publications

This study sought to determine if qualitative alterations in skeletal muscle mitochondrial respiration, associated with decreased mitochondrial efficiency, contribute to exercise intolerance in patients with chronic obstructive pulmonary disease (COPD). Using permeabilized muscle fibers from the vastus lateralis of 13 patients with COPD and 12 healthy controls, complex I (CI) and complex II (CII)-driven State 3 mitochondrial respiration were measured separately (State 3:CI and State 3:CII) and in combination (State 3:CI+CII). State 2 respiration was also measured. Exercise tolerance was assessed by knee extensor exercise (KE) time to fatigue. Per milligram of muscle, State 3:CI+CII and State 3:CI were reduced …

Low Intensity Resistance Exercise Training With Blood Flow Restriction: Insight Into Cardiovascular Function, And Skeletal Muscle Hypertrophy In Humans, Song-Young Park, Yi Sub Kwak, Andrew Harveson, Joshua C. Weavil, Kook E. Seo

Health and Kinesiology Faculty Publications

Attenuated functional exercise capacity in elderly and diseased populations is a common problem, and stems primarily from physical inactivity. Decreased function and exercise capacity can be restored by maintaining muscular strength and mass, which are key factors in an independent and healthy life. Resistance exercise has been used to prevent muscle loss and improve muscular strength and mass. However, the intensities necessary for traditional resistance training to increase muscular strength and mass may be contraindicated for some at risk populations, such as diseased populations and the elderly. Therefore, an alternative exercise modality is required. Recently, blood flow restriction (BFR) with …

Research Presentations

PURPOSE: Validate the Schoche (SC) (RhythmTM), Basis B1 Band (BB) (BASIS Science, Inc.), and Mio Alpha (MA) (Physical Enterprises, Inc.) wireless heart rate monitors. METHODS: Fifteen college students (males, n=11, age=27±5yrs; females, n=4, age=27±6yrs) participated. All participants simultaneously wore the SC on left forearm, the BB on the right wrist, the MA on the left wrist, and Polar HR strap on their chest. Participants’ resting heart rate was measured twice prior to exercise. The exercise protocol consisted of one 30-minute bout of continuous walking and running in which the treadmill speed increased every 5-minutes. The treadmill started at 2 …

Validity Of The Ihealth-Bp7 And Withings-Bp800 Self Measurement Blood Pressure Monitor, Hyun-Sung An, Matthew Bubak, Danae M. Dinkel, Dustin Slivka, Jung-Min Lee

Research Presentations

PURPOSE: The purpose of this study is to validate the iHealth-BP7 and Withings-BP800 monitors according to the European Society of Hypertension (ESH) International Protocol revision 2010. METHODS: Data from 11 participants (31.6 ± 2.2 years) were initially examined according to the ESH International Protocol for the validation of BP measuring devices. Participants were asked to sit and relax for 10-15 mins with legs uncrossed, and back supported prior to the test. In all participants, sequential left arm measurements were performed by two trained observers using a mercury sphygmomanometer and one supervisor using the device. Collected data were screened …

Validity Of Wearable Activity Monitors For Estimation Of Resting Energy Expenditure In Adults, Zachary Motz, Yang Bail, Youngwon Kim, Danae M. Dinkel, Jung-Min Lee

Research Presentations

• Wearable accelerometers have become the standard method for assessing physical activity for both individuals and field-based research [1]. These new devices allow consumers to have the ability to estimate total energy expenditure and track it over time. • Resting Energy Expenditure plays a critical role in estimating daily total energy expenditure as it contributes 60-70% of total energy expenditure [2,3]. • Little to no information is available to substantiate the validity of these consumer-based activity monitors under free-living conditions.
