Fecal Microbiota and Associated Metabolites Are Minimally Affected by Ten Weeks of Resistance Training in Younger and Older Adults Open
Preclinical evidence suggests that short chain fatty acids (SCFAs) produced by gut microbiota may impact body composition and muscle growth. While aging is implicated in negative alterations to the gut microbiome, exercise may mitigate the…

The effects of resistance training to near volitional failure on motor unit recruitment during neuromuscular fatigue Open
Background It is unclear whether chronically training close to volitional failure influences motor unit recruitment strategies during fatigue. Purpose We compared resistance training to near volitional failure vs . non-failure on individua…

Peripheral quantitative computed tomography is a valid imaging technique for tracking changes in skeletal muscle cross‐sectional area Open
Peripheral quantitative computed tomography (pQCT) has recently expanded to quantifying skeletal muscle, however its validity to determine muscle cross‐sectional area (mCSA) compared to magnetic resonance imaging (MRI) is unknown. Eleven m…

Resistance training in humans and mechanical overload in rodents do not elevate muscle protein lactylation Open
Although several reports have hypothesized that exercise may increase skeletal muscle protein lactylation, empirical evidence in humans is lacking. Thus, we adopted a multi-faceted approach to examine if acute and subchronic resistance tra…

The effects of resistance training to near failure on strength, hypertrophy, and motor unit adaptations in previously trained adults Open
Limited research exists examining how resistance training to failure affects applied outcomes and single motor unit characteristics in previously trained individuals. Herein, resistance‐trained adults (24 ± 3 years old, self‐reported resis…

Molecular predictors of resistance training outcomes in young untrained female adults Open
This study continues to delineate muscle biology differences between lower and higher responders to resistance training and is unique in that a female population was interrogated. As has been reported in prior studies, increases in satelli…

Exploring the Effects of Six Weeks of Resistance Training on the Fecal Microbiome of Older Adult Males: Secondary Analysis of a Peanut Protein Supplemented Randomized Controlled Trial Open
The bacteria inhabiting the gastrointestinal tract contribute to numerous host functions and can be altered by lifestyle factors. We aimed to determine whether a 6-week training intervention altered fecal microbiome diversity and/or functi…

Effects of High-Volume Versus High-Load Resistance Training on Skeletal Muscle Growth and Molecular Adaptations Open
We evaluated the effects of higher-load (HL) versus (lower-load) higher-volume (HV) resistance training on skeletal muscle hypertrophy, strength, and muscle-level molecular adaptations. Trained men ( n = 15, age: 23 ± 3 years; training exp…

Effects of Peanut Protein Supplementation on Resistance Training Adaptations in Younger Adults Open
Protein supplementation is a commonly employed strategy to enhance resistance training adaptations. However, little research to date has examined if peanut protein supplementation is effective in this regard. Thus, we sought to determine i…

Myofibril and Mitochondrial Area Changes in Type I and II Fibers Following 10 Weeks of Resistance Training in Previously Untrained Men Open
Resistance training increases muscle fiber hypertrophy, but the morphological adaptations that occur within muscle fibers remain largely unresolved. Fifteen males with minimal training experience (24±4years, 23.9±3.1kg/m 2 body mass index)…

Effects of High-Volume versus High-Load Resistance Training on Skeletal Muscle Growth and Molecular Adaptations Open
Aim We evaluated the effects of higher-load (HL) versus (lower-load) higher-volume (HV) resistance training on skeletal muscle hypertrophy, strength, and muscle-level molecular markers. Methods Trained men (n=15, age: 23±3 y; training expe…

Myofibril and Mitochondrial Area Changes in Type I and II Fibers Following 10 Weeks of Resistance Training in Previously Untrained Men Open
Resistance training increases myofiber hypertrophy, but the morphological adaptations that occur within myofibers remain largely unresolved. Fifteen males with minimal training experience (24±4 years, 17.9±1.4 kg/m2 lean body…

The effects of resistance training with or without peanut protein supplementation on skeletal muscle and strength adaptations in older individuals Open
Several studies suggest resistance training (RT) while supplementing with various protein supplements can enhance strength and muscle mass in older individuals. However, to date, no study has examined the effects of RT with a peanut protei…

The Effects of Resistance Training With or Without Peanut Protein Supplementation on Skeletal Muscle and Strength Adaptations in Older Individuals Open
Several studies suggest resistance training (RT) with protein supplementation has positive effects on strength and muscle mass in older individuals. However, to date, no study has examined the effects of RT with a high-protein, defatted pe…

Acute and chronic effects of resistance training on skeletal muscle markers of mitochondrial remodeling in older adults Open
We investigated the acute and chronic effects of resistance training (RT) on skeletal muscle markers of mitochondrial content and remodeling in older, untrained adults. Sixteen participants (n = 6 males, n = 10 females; age = 59 ± 4 years)…
