Research and Physiological Mechanisms

Physiology

Examination of the relationship between lean tissue and daily energy expenditure from longitudinal trials and cross-sectional studies.

Energy Expenditure

Overview of EPOC, substrate oxidation, and metabolic responses documented in controlled laboratory trials.

Adaptations

Chronic changes in muscle fiber size and lean mass observed across diverse populations over training periods.

Comparative

Energy expenditure profiles, adaptations, and physiological distinctions between resistance and aerobic modalities.

Population Research

Population-level associations between muscle mass indices and energy balance outcomes in observational cohorts.

Methodology

Methodological considerations, confounders, measurement challenges, and critical interpretation of study findings.
