International Journal of Exercise Science
International Journal of Exercise Science 11(5): 226-238, 2018. The American College of Sports Medicine (ACSM) has recommended that resistance training be performed at least twice per week, with 8-12 repetitions of 8-10 exercises targeting all major muscle groups (1). However, Kruger, Carlson, and Kohl (18) reported that women were participating less than the U.S. population on the whole, as only 20% of women were engaging in resistance training two or more times per week. In order to better understand why only 1 in 5 women participate regularly in this form of physical activity, this study investigated current resistance training practices, …

Effects Of Single-Dose Dietary Nitrate On Oxygen Consumption During And After Maximal And Submaximal Exercise In Healthy Humans, Genevieve M. Kocoloski, Anne R. Crecelius
International Journal of Exercise Science
International Journal of Exercise Science 11(3): 214-225, 2018. Dietary nitrate (NO3-) has been shown to reduce oxygen consumption (VO2) during moderate to high-intensity (e.g. time to fatigue, time trials) exercise and often in trained athletes. However, less is known regarding prolonged exercise and the potential impact of NO3- on post-exercise excess oxygen consumption (EPOC), particularly in untrained individuals, who may have different metabolic goals during exercise than trained individuals. We tested the hypothesis that acute nitrate supplementation in the form of beet root juice will significantly decrease both VO2 during maximal exercise …

Physical Therapy Considerations For Chronic Kidney Disease And Secondary Sarcopenia, Michael O. Harris-Love, Haniel J. Hernandez, Gideon Obamwonyi
Exercise and Nutrition Sciences Faculty Publications
Chronic kidney disease (CKD) is a progressive condition that may negatively affect musculoskeletal health. These comorbidities may include malnutrition, osteoporosis, and decreased lean body mass. Secondary sarcopenia due to CKD may be associated with mobility limitations and elevated fall risk. Physical therapists are well-positioned among the health care team to screen for secondary sarcopenia in those with CKD and for the treatment of musculoskeletal comorbid conditions that may affect functional performance. Given the consequences of both low muscle mass and low bone mineral density, appropriate and timely physical therapy is important for fall risk assessment and intervention to minimize the …

Faculty Publications
Comprehensive school physical activity programs (CSPAPs) have been endorsed as a promising strategy to increase youth physical activity (PA) in school settings. A CSPAP is a five-component approach, which includes opportunities before, during, and after school for PA. Extensive resources are available to public health practitioners and school officials regarding what should be implemented, but little guidance and few resources are available regarding how to effectively implement a CSPAP. Implementation science provides a number of conceptual frameworks that can guide implementation of a CSPAP, but few published studies have employed an implementation science framework to a CSPAP. Therefore, we developed …

International Journal of Exercise Science
International Journal of Exercise Science 11(4): 198-213, 2018. The influence of baseline strength or muscle size on adaptations to training is not well-understood. Comparisons between novice and advanced lifters, and between stronger and weaker experienced-lifters, have produced conflicting results. This study examined the effect of baseline muscle strength and size on subsequent adaptations in resistance-trained individuals following a traditional high-volume, short-rest resistance training protocol. Fourteen resistance-trained men (24.0±2.7 y; 90.1±11.7 kg; 169.9±29.0 cm) completed pre-training (PRE) ultrasound measurements of muscle cross-sectional area (CSA) in the rectus femoris (RF), vastus lateralis (VL), pectoralis major, and triceps brachii (TRI) prior to strength …

The Effect Of A Single Bout Of High Intensity Intermittent Exercise On Glucose Tolerance In Non-Diabetic Older Adults, Hannah M. Lithgow, Melanie Leggate
International Journal of Exercise Science
International Journal of Exercise Science 11(3): 95-105, 2018. Our aim was to investigate the acute effects of a single bout of high intensity intermittent training (HIIT) on glucose tolerance and other physiological and metabolic markers in non-diabetic older adults. Fourteen healthy older adults (age, 64 ± 2 y; BMI, 25.7 ± 2.8 kg·m-2) performed two acute exercise trials: continuous moderate intensity exercise (MOD) and HIIT, with the response to an oral glucose tolerance test (OGTT) determined <24 hours after. Inflammatory, haematological, and lipid parameters were also assessed the day after each trial. There was an effect of the trials on the insulin response to an OGTT (P=0.047), but not the glucose response. Following an acute bout of HIIT, insulin concentration during an OGTT was elevated at 60 min compared to the control trial (P=0.045), indicating more insulin was secreted, but glucose concentration was unchanged in all trials. The study findings demonstrate that a single bout of HIIT affects the insulin response but not the glycaemic response to a glucose load, proffering a potential benefit for metabolic health in older adults.
