Locally applied heat stress during exercise training may promote adaptations to mitochondrial enzyme activities in skeletal muscle

The aim of this study was to determine if elevating muscle temperature during exercise through the application of mild, local heat stress would promote adaptations to mitochondrial protein content in response to endurance training.

Skeletal muscle proteins involved in fatty acid transport influence fatty acid oxidation rates observed during exercise

The purpose of this study was to investigate skeletal muscle proteins involved in fatty acid oxidation.

The influence of dietary carbohydrate on perceived recovery status differs at the group and individual level – evidence of nonergodicity among endurance athletes

The purpose of this study was to examine the relationship between daily carbohydrate intake and perceived recovery status and determine if group-level statistics can generalize to individual athletes.

A three-minute all-out test performed in a remote setting does not provide a valid estimate of the maximum metabolic steady state

The aim of the present investigation was to determine the reliability and validity of the 3MT for estimation of the MMSS when performed in remote settings by unsupervised athletes using their own indoor cycling setup.

Factors Influencing Substrate Oxidation During Submaximal Cycling - A Modelling Analysis

The purpose of this analysis was to investigate factors influencing the RER during cycling exercise and formulate regression models to determine which factors best explain RER during exercise, their relative influence, and the result of multiple variables being modulated simultaneously.

Factors Influencing AMPK Activation During Cycling Exercise - A Pooled Analysis and Meta‐Regression

The purpose of this analysis was to (1) investigate correlations between factors influencing AMPK activation and the magnitude of change in AMPK activity during cycling exercise, (2) investigate correlations between commonly reported measures of AMPK activation (AMPK-a2 activity, phosphorylated (p)-AMPK, and p-acetyl coenzyme A carboxylase (p-ACC), and (3) formulate linear regression models to determine the most important factors for AMPK activation during exercise.

Pre-Exercise Carbohydrate or Protein Ingestion Influences Substrate Oxidation but Not Performance or Hunger Compared with Cycling in the Fasted State

The aim of this crossover study was to determine the effects of three different pre-exercise nutrition strategies on substrate oxidation, performance during HIIT, and exercise-induced oxidative stress.

Racing and Training Physiology of an Elite Ultra-Endurance Cyclist - Case Study of 2 Record-Setting Performances

A case report of an elite ultra-endurance cyclist, who was the winner and course record holder of 2 distinct races within a 4-month span - a 24-hour solo cycling race (Bike Sebring 24 h) and a 2-man team multiday race (RAAM).

Effect of low- and high-carbohydrate diets on swimming economy - a crossover study

The aim of this study was to determine the influence of three days of high- and low-carbohydrate diets on the energetic cost of submaximal swimming.

What should I eat before exercise? Pre-exercise nutrition and the response to endurance exercise - Current prospective and future directions

The purpose of this review is to highlight the current knowledge of the influence of pre-exercise nutrition ingestion on the metabolic, physiological, and performance responses to endurance training. We also highlight areas for practitioners where evidence is lacking, particularly regarding trained athletes, and suggest directions for future research.
