Journal Article
Exogenous carbohydrate form during low-muscle glycogen conditions has minimal impact on cycling performance
Background Skeletal muscle recovery is improved with immediate postexercise carbohydrate feeding. Little is known regarding muscle recovery and performance when feeding is delayed. The purpose of this study was to examine the effects of varying exogenous carbohydrates on cycling performance with…

Seasonal changes in energy intake and emerging indicators of energy availability in young elite Nordic skiers
Background Nordic skiing, an energy-demanding endurance sport, may be particularly susceptible to low energy availability (LEA) and relative energy deficiency in sport (REDs). The objective was to examine the nutritional practices and physical symptoms associated with (REDs among young elite…

Journal Article
Intra-individual reliability of blood bicarbonate responses and gastrointestinal symptoms following sodium citrate supplementation
Background Sodium citrate (SC) can elevate extracellular buffering capacity, yet the intra-individual reliability of its blood bicarbonate ([HCO₃−]) kinetics and gastrointestinal (GI) responses is unclear, limiting individualized dosing strategies.Methods Twelve healthy males (21 ± 1 yr) ingested a…

Journal Article
A comprehensive review of the physiology and evidence base to guide the use of ergogenic and medical supplements for enhanced cycling performance
Background A growing body of evidence supports the use of supplements to enhance cycling performance through both direct and indirect mechanisms.Methods This review was informed by a structured literature search conducted in PubMed, Scopus and Web of Science for peer-reviewed studies published up…

Beetroot juice supplementation enhances the effects of blood flow restriction training on lower limb strength and vertical jump performance under fatigue in male university students: a randomized, double-blind, placebo-controlled study
Background Beetroot juice (BRJ) supplementation has the potential to enhance the effects of blood flow restriction (BFR) training in improving muscle strength and fatigue resistance; however, evidence supporting their combined effects remains limited. This study investigated whether BRJ…

Journal Article
Revisiting the evidence on caffeine mouth rinse: effects on exercise and cognitive performance: a meta-analytic review
Background Caffeine mouth rinsing (Caff-MR) may activate oropharyngeal receptors and rapidly engage central networks for motivation, attention, and pacing without systemic absorption. The only prior meta-analysis found no stable ergogenic effect, yet the evidence base has continued to expand and…

Journal Article
A systematic and critical review of measurement scales for evaluating gastrointestinal symptoms during exercise
Background Exercise-induced gastrointestinal symptoms (GIS) are commonly reported, with either Likert-type scales or visual analog scales (VAS) used to quantify the incidence and magnitude of symptoms. However, these measurement tools lack consistency in their design, reporting, and key aspects…

Journal Article
Effects of acute Capsaicin analogue intake on athletic performance: a three-level meta-analysis
Background Capsaicin analogues have been proposed as potential ergogenic aids, but their acute effects on athletic performance remain inconsistent. This study aimed to evaluate the effects of acute capsaicin analogue intake on exercise performance using a three-level meta-analysis.Methods PubMed…

Journal Article
Effects of dietary supplements on lower-limb power and jump performance in physically active individuals and athletes: a systematic review and Bayesian network meta-analysis
Objective To evaluate the relative effects of dietary supplements, the certainty of evidence, and the robustness of findings within separate networks for peak power (PP), relative peak power (RPP), vertical jump (VJ), and countermovement jump (CMJ).Methods PubMed, Web of Science, Embase, and the…

Journal Article
Resistance training combined with creatine supplementation: a three-level meta-analysis of multidimensional outcomes from strength enhancement to body composition remodeling
Objective This study aimed to determine (1) the effects of resistance training combined with creatine supplementation on muscle strength (upper- and lower-body strength) and body composition (lean mass, fat mass, body-fat percentage, and body mass), and (2) whether these effects were moderated by…

Journal Article
A 12-week, double-blind, quasi-randomized, placebo-controlled study to evaluate the efficacy and safety of Coleus forskohlii (Forcslim) on body weight loss
Background Overweight and obesity have emerged as a global epidemic, significantly impacting human health. Traditional usage and growing scientific evidence suggest that Coleus forskohlii extract (Forcslim) may aid in reducing excess body weight and fat. This study aimed to evaluate the efficacy…

Journal Article
Agreement and repeatability between manual anthropometry and mobile 3D digital anthropometry in young adults
Background Mobile 3D digital anthropometry has emerged as a rapid and accessible alternative to manual anthropometry. However, evidence regarding its agreement with manual methods and its suitability for interchangeable use remains limited, particularly when raw anthropometric variables are…

Journal Article
Effects of carnosine supplementation on physical endurance: a placebo-controlled randomized clinical trial
Background Carnosine (β-alanine-L-histidine) is an endogenous dipeptide found in abundance in highly metabolic tissues such as skeletal muscle and the brain, where it is thought to play a role in intracellular buffering, and thereby, promote anaerobic glycolysis. Due to its perceived ability to…
