PURPOSE: Unaccustomed eccentric (ECC) exercise evokes exercise-induced muscle damage (EIMD). Soreness, strength loss and serum creatine kinase (CK) are often used to quantify EIMD severity. However, changes in these markers are not fully understood mechanistically. To test the hypothesis that muscle damage markers are associated with unique molecular processes, we correlated gene expression responses with variation in each marker post-ECC. METHODS: Vastus lateralis biopsies were collected from 35 young men 3-hr post-ECC (10 sets of 10 maximal eccentric contractions; contralateral leg (CON) as control)...

INTRODUCTION: The US Army Load Carriage Decision Aid (LCDA) metabolic model is used by militaries across the globe and is intended to predict physiological responses, specifically metabolic costs, in a wide range of dismounted warfighter operations. However, the LCDA has yet to be adapted for vest-borne load carriage, which is commonplace in tactical populations, and differs in energetic costs to backpacking and other forms of load carriage. PURPOSE: Develop and validate a metabolic model term that accurately estimates the effect of weighted vest loads on standing and walking metabolic rate for military mission-planning and general applications...

PURPOSE: Understanding muscle-tendon forces (e.g., triceps surae and Achilles tendon) during locomotion may aid in the assessment of human performance, injury risk, and rehabilitation progress. Shear wave tensiometry is a noninvasive technique for assessing in vivo tendon forces that has been recently adapted to a wearable technology. However, previous lab-based and outdoor tensiometry studies have not evaluated running. This study was undertaken to assess the capacity for shear wave tensiometry to produce valid measures of Achilles tendon loading during running at a range of speeds...

INTRODUCTION: Trauma-induced hemorrhage is a leading cause of death in prehospital settings. Experimental data demonstrate that females have a lower tolerance to simulated hemorrhage (i.e., central hypovolemia). However, the mechanism(s) underpinning these responses are unknown. Therefore, this study aimed to compare autonomic cardiovascular responses during central hypovolemia between the sexes. We hypothesized that females would have a lower tolerance and smaller increase in muscle sympathetic nerve activity (MSNA) to simulated hemorrhage...

INTRODUCTION: Early life growth-restriction significantly increases the risk of adulthood physical inactivity and thereby chronic disease incidence. Improvements in motor skill acquisition could result in greater physical activity engagement in the growth-restricted population thus reducing chronic disease risk. The purpose of this study was to implement an early life motor training intervention to improve physical activity engagement in control and growth-restricted mice. METHODS: Mice were growth-restricted in early life utilizing a validated nutritive model or remained fully nourished in early life as a control...

PURPOSE: High-intensity interval training (HIIT) can efficiently decrease total and (intra-) abdominal fat mass (FM); however, the effects of running versus cycling HIIT programs on FM reduction have not been compared yet. Additionally, the link between HIIT-induced FM reduction and gut microbiota must be better investigated. The aim of this study was to compare the effects of two 12-week HIIT isoenergetic programs (cycling vs. running) on body composition and fecal microbiota composition in nondieting men with overweight or obesity...

PURPOSE: In competitive sport, classic methods of measuring drug prevalence, such as doping controls or questionnaires, are challenging. Here we describe a novel urine sampling method to measure drug use in athletes. We hypothesize that the prevalence of drug use in ultramarathon runners is measured more accurately with our sampling method than randomized-response questionnaires. METHODS: Urine samples and associated demographic data were collected from male participants using blind, automated urinals at the start of ultramarathon races...

PURPOSE: The purpose of this study was to determine whether regular running distance and biomechanics are related to medial central femur cartilage (MCFC) structure. METHODS: The cross-sectional study sample consisted of 1164 runners and non-runners aged 18-65 years. Participants completed questionnaires on physical activity and their running history. We performed quantitative magnetic resonance imaging of knee cartilage - T2 relaxation time (T2) mapping (high T2 indicate cartilage degeneration), and a running biomechanical analysis using a 3-D motion capture system...

PURPOSE: Muscle mechanics is paramount in our understanding of motor performance. However, little is known regarding the sensitivity of fascicle dynamics and connective tissues stiffness to exercise duration and ambient temperature during running, both increasing muscle temperature. This study aimed to determine gastrocnemius medialis (GM) fascicle dynamics in vivo during running in temperate and hot conditions, as well as muscle-tendon unit responses. METHODS: Using ultrafast ultrasound, fifteen participants (8 men, 7 women, 26 ± 3 years) were tested before, during (2 and 40 min) and after a running task (40 min at 10 km...
