Human skeletal muscle demonstrates remarkable plasticity, adapting to numerous external stimuli including the habitual level of contractile loading. Accordingly, function and exercise capacity encompass a broad spectrum, from inactive individuals with low levels endurance strength elite athletes who produce prodigious performances underpinned by pleiotropic training-induced muscular adaptations. Our current understanding signal integration, interpretation, output coordination cellular molecular mechanisms that govern plasticity across this continuum is incomplete. As such, training methods their application largely rely on “trial-and-error” approach, experience practices successful coaches often providing bases for “post hoc” scientific enquiry research. This review provides synopsis morphological functional changes along underlying adaptation endurance- resistance-based training. These traits are placed in context innate genetic interindividual differences performance, special consideration given aging athletes. Collectively, we provide comprehensive overview response different modes how such adaptations translate “molecules medals.”

Exercise training is critical for the prevention and treatment of obesity, but its underlying mechanisms remain incompletely understood given challenge profiling heterogeneous effects across multiple tissues cell types. Here, we address this opposing exercise high-fat diet (HFD)-induced obesity at single-cell resolution in subcutaneous visceral white adipose tissue skeletal muscle mice with interventions. We identify a prominent role mesenchymal stem cells (MSCs) exercise-induced adaptation. Among pathways regulated by HFD MSCs three tissues, extracellular matrix remodeling circadian rhythm are most prominent. Inferred cell-cell interactions implicate within- multi-tissue crosstalk centered around MSCs. Overall, our work reveals intricacies diversity molecular responses to uncovers previously underappreciated tissue-specific beneficial exercise.
