Caffeine, but not paracetamol (acetaminophen), enhances muscular endurance, strength, and power

Journal of the International Society of Sports Nutrition
Background Caffeine is one of the most popular ergogenic aids consumed by athletes. Caffeine’s ergogenic effect has been generally explained by its ability to bind to adenosine receptors, thus modulating pain and reducing perceived exertion.

Catecholaminergic Contributions to Inhibitory Control Following Physical Fatigue: Behavioral and Neurophysiological Findings

European Journal of Sport Science, Volume 26, Issue 9, September 2026.
ABSTRACT Acute physical fatigue can impair cognitive control, yet its underlying neurochemical mechanisms remain unclear. This study investigated whether catecholaminergic modulation influences behavioral and neural markers of inhibitory control following physical fatigue.

From Macronutrients to Functional Foods: Nutritional Strategies for Recovery Following High‐Intensity Exercise

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
Recovery nutrition after high‐intensity exercise should be hierarchical and periodized. Carbohydrate and protein form the foundation for glycogen restoration and muscle repair, while functional foods and bioactive compounds serve as context‐dependent adjuncts.

Acute pre‐exercise oral intake of cacao polyphenols attenuates central fatigue development during sustained low‐intensity ankle dorsiflexion exercise in healthy young male adults

Physiological Reports, Volume 14, Issue 17, September 2026.
Abstract This double‐blind, randomized, crossover study investigated whether acute cacao polyphenol (CP) ingestion attenuates neuromuscular fatigue in 19 healthy young male adults. After consuming CP or placebo, participants performed sustained isometric ankle dorsiflexion at 25% of maximal voluntary isometric contraction (MVIC) torque until task ...

Passive thigh heating increases peak torque but does not attenuate declines in force production during repeated isokinetic knee extensor exercise in older adults

Physiological Reports, Volume 14, Issue 18, September 2026.
Abstract Aging is associated with declines in muscle function, leading to increased functional fatigability. Passive heating has demonstrated positive effects on muscle function during brief exercise in older adults, but the impact of heating on repeated contractions remains unknown.

The Regulation and Expression of the Creatine Transporter: A Brief Review of Creatine Supplementation in Humans and Animals

Journal of the International Society of Sports Nutrition, 2006
Creatine monohydrate has become one of the most popular ergogenic sport supplements used today. It is a nonessential dietary compound that is both endogenously synthesized and naturally ingested through diet. Creatine ingested through supplementation has
