Muscle builders frequently consume protein supplements, but little is known about their effect on the gut microbiota. This study compared the gut microbiome and metabolome of selfidentified muscle builders who did or did not report consuming a protein supplement. Twenty-two participants (14 males and 8 females) consumed a protein supplement (PS), and seventeen participants (12 males and 5 females) did not (No PS). Participants provided a fecal sample and completed a 24-h food recall (ASA24). The PS group consumed significantly more protein (118 ± 12 g No PS vs. 169 ± 18 g PS, p = 0.02). Fecal metabolome and …

Is It Time To Rethink Our Weight Loss Paradigms?, Paulo Gentil, Ricardo Borges Viana, João Pedro Naves, Fabrício Boscolo Del Vecchio, Victor Coswig, Jeremy Loenneke, Claudio André Barbosa

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Strategies aiming to promote weight loss usually include anything that results in an increase in energy expenditure (exercise) or a decrease in energy intake (diet). However, the probability of losing weight is low and the probability of sustained weight loss is even lower. Herein, we bring some questions and suggestions about the topic, with a focus on exercise interventions. Based on the current evidence, we should look at how metabolism changes in response to interventions instead of counting calories, so we can choose more efficient models that can account for the …

Resistance Training Volume Load With And Without Exercise Displacement, W. Guy Hornsby, Jeremy A. Gentles, Paul Comfort, Timothy J. Suchomel, Satoshi Mizuguchi, Michael H. Stone

ETSU Faculty Works

Monitoring the resistance training volume load (VL) (sets × reps × load) is essential to managing resistance training and the recovery–adaptation process. Subjects: Eight trained weightlifters, seven of which were at national level, participated in the study. Methods: VL was measured both with (VLwD) and without (VL) the inclusion of barbell displacement, across twenty weeks of training, in order to allow for comparisons to be made of these VL calculating methods. This consisted of recording the load, repetition count, and barbell displacement for every set executed. Comparisons were made between VL and VLwD for individual blocks of training, select training …

Increases In Variation Of Barbell Kinematics Are Observed With Increasing Intensity In A Graded Back Squat Test, Kevin M. Carroll, Kimitake Sato, Caleb D. Bazyler, N. Travis Triplett, Michael H. Stone

ETSU Faculty Works

The purpose of the current study was two-fold: (1) To examine the variation in velocity and power with increasing intensity in the back squat among subjects; and (2) To explore individual subject characteristics as possible explanations for variations of velocity in the back squat. Fourteen recreationally trained male subjects with experience in the back squat agreed to participate in the study (age = 25.0 ± 2.6 years, height = 178.9 ± 8.1 cm, body mass = 88.2 ± 15.8 kg). One-repetition maximums (1RM) were performed for each subject on force platforms with four linear position transducers attached to the barbell. …

Cell Free Dna As A Marker Of Training Status In Weightlifters, Jeremy A. Gentles, William G. Hornsby, Christine L. Coniglio, Andy R. Dotterweich, Jon A. Miller, Charles A. Stuart, Michael H. Stone

ETSU Faculty Works

The purpose of this investigation was to elucidate the changes in cf-DNA as it relates to fluctuations in resistance training workloads and intensities. The relationship between cell free DNA (cf-DNA), C-reactive protein (CRP), creatine kinase (CK), testosterone (T), cortisol (C), testosterone-cortisol ratio (T:C), body mass and body composition were also examined. Eight weightlifters (5 males and 3 females, age = 25 ± 3.5 yr, body mass = 88.3 ± 22.7 kg, height = 173.8 ±8.4 cm) volunteered to participate in this study. Venous blood samples, body mass and body composition were taken six times, each corresponding to the end of …

Multi-Modal Exercise Training And Protein-Pacing Enhances Physical Performance Adaptations Independent Of Growth Hormone And Bdnf But May Be Dependent On Igf-1 In Exercise-Trained Men, Stephen J. Ives, Chelsea Norton, Vincent Miller, Olivia Minicucci, Jake Robinson, Gabe O'Brien, Daniela Escudero, Maia Paul, Caitlin Sheridan, Kathryn Curran, Kayla Rose, Nathaniel Robinson, Feng He, Paul J. Arciero

OBJECTIVE: Protein-pacing (P; 5-6meals/day @ 2.0g/kgBW/day) and multi-mode exercise (RISE; resistance, interval, stretching, endurance) training (PRISE) improves muscular endurance, strength, power and arterial health in exercise-trained women. The current study extends these findings by examining PRISE on fitness, growth hormone (GH), insulin-like growth factor-1 (IGF-1), and brain-derived neurotrophic factor (BDNF) response, cardiometabolic health, and body composition in exercise-trained men.

DESIGN: Twenty active males (>4daysexercise/week) completed either: PRISE (n=11) or RISE (5-6meals/day @ 1.0g/kgBW/day; n=9) for 12weeks. Muscular strength (1-repetition maximum bench and leg press, 1-RM BP, and 1-RM LP), endurance (sit-ups, SU; push-ups, PU), power (squat jump, SJ, and …

Effects Of 8 Weeks Of Flexibility And Resistance Training In Older Adults With Type 2 Diabetes, Matthew T. Herriot, Sheri R. Colberg, Henri K. Parson, Tanja Nunnold, Aaron I. Vinik

Human Movement Sciences & Special Education Faculty Publications

(First paragraph) Flexibility is often downplayed as unimportant to fitness. However, flexibility training is imperative to maintain full range of motion (ROM) of joints, particularly in individuals with type 2 diabetes, who may experience limited joint mobility due to glycation of joint structures (1). Maladies such as “frozen shoulder” are common complaints in type 2 diabetes (2).
