An Exploratory Analysis Of The Role Of Sex In Load Carriage, Rachel E. Perez, Dustin R. Slivka, Brent C. Ruby

Graduate Student Theses, Dissertations, & Professional Papers

Axially loaded weight may impose a metabolic demand equivalent to that of fat mass (FM) during load carriage. Males (M) typically have a lower body fat percentage than females (F), resulting in metabolic demand differences during load carriage that may be mitigated by accounting for FM in pack loads. PURPOSE: To determine whether normalizing pack load to FM equalizes metabolic cost across sexes during load carriage. METHODS: Twenty-eight participants (14M, 23 ± 5 y, 1.81 ± 0.07 m, 78.7 ± 10.0 kg, 12.7 ± 5.4% body fat, VO₂peak 4.18 ± 0.54 L·min^-1; 14F, 22 ± 4 …

Menopause-Related Changes In Sleep And The Associations With Cardiometabolic Health: A Narrative Review, Joshua R. Sparks, Xuewen Wang Ph.D., Faha

Faculty Publications

This narrative review examines the complex relationship between sleep changes during the menopausal transition and cardiometabolic risks. The most common complaint about sleep is increased awakenings during sleep. Other complaints include having trouble falling asleep, waking up too early, insufficient and non-restorative sleep, and overall poor quality. Sleep determined using objective methods also indicates that greater awakenings after sleep onset are associated with the period of menopausal transition. Polysomnography recordings suggest physiological hyperarousal during sleep. Changes in other sleep metrics, such as sleep latency and sleep duration, are less consistent, and some studies suggest they may not worsen during the …

Validation Of Head Above And Head Submerged Hydrostatic Weighing Equations And Air Displacement Plethysmography, Axel M. Miller

The Effects Of Low Volume High-Intensity Interval Training Vs. Moderate-Intensity Interval Training With Blood Flow Restriction On Body Composition, Hormone Concentration, And Arterial Elasticity In Overweight And Obese Male Adults, Alexis Lopez

Theses and Dissertations

PURPOSE: This study compared the effects of HIIT and MIIT+BFR on the adaptations in body composition, salivary hormone concentration, peak oxygen uptake, anaerobic parameters, and arterial elasticity in young overweight and obese male adults.

RESULTS: There was a significant increase in total BMC (p<0.01), leg BMC (p<0.05), and trunk BMC (p<0.05) from baseline in response to HIIT. MIIT+BFR significantly increased LFM/TFM Ratio from baseline (p<0.01). HIIT significantly decreased AIx@75 (p<0.05) and CI (p<0.05). There was a significant increase in ISO 180o Away (p<0.05), Thor Begin. (p<0.01), and Thor Mid. (p<0.05) in response to HIIT. MIIT+BFR had a superior increase in Thor Mid. (p<0.05) and significantly increased ISO 180o Toward (p<0.01), VO2peak (p<0.05), and VO2peak:Time (p<0.05). In the last training session, HIIT significantly increased salivary leptin (p<0.05), but MIIT+BFR had a superior increase in salivary leptin (p<0.01) from pre- to post exercise.

CONCLUSION: HIIT significantly improved total BMC, leg BMC, trunk BMC, and AIx@75 but decreased CI from baseline. HIIT increased quad muscle strength, whereas MIIT+BFR increased hamstring muscle strength. HIIT and MIIT+BFR significantly increased peak torque in Thor Mid and salivary leptin. Only MIIT+BFR significantly improved VO2peak.
