Despite the steady increase in female participation in sport over the last two decades, comprehensive research on interventions attenuating the influence of female menstrual physiology on performance remains scarce. Studies involving eumenorrheic women often only test in one menstrual phase to limit sex hormone variance, which may restrict the application of these findings to the rest of the menstrual cycle. The impacts of nutrition-based interventions on athletic performance throughout the menstrual cycle have not been fully elucidated. We addressed this gap by conducting a focused critical review of clinical studies that reported athletic outcomes as well as menstrual status for healthy eumenorrheic female participants. In total, 1443 articles were identified, and 23 articles were included. These articles were published between 2011 and 2021, and were retrieved from Google Scholar, Medline, and PubMed. Our literature search revealed that hydration-, micronutrient-, and phytochemical-based interventions can improve athletic performance (measured by aerobic capacity, anaerobic power, and strength performance) or attenuate exercise-induced damage (measured by dehydration biomarkers, muscle soreness, and bone resorption biomarkers). Most performance trials, however, only assessed these interventions in one menstrual phase, limiting the application throughout the entire menstrual cycle. Improvements in athletic performance through nutrition-based interventions may be contingent upon female sex hormone variation in eumenorrheic women.

El masaje es una de las terapias más utilizadas para aliviar el dolor muscular tardío (DMT). El objetivo del presente estudio fue determinar la efectividad del masaje en el tratamiento del DMT, para lo cual se llevó a cabo una revisión sistemática en las bases de datos, Pubmed, Scopus, SportDiscus, Web of Science y el buscador Google académico, usando las palabras clave delayed onset muscle soreness y exercise induced muscle damage combinado con massage. Se incluyeron en el estudio 23 artículos en los cuales el 78% mostró disminución del DMT mientras que en el restante 22% no hubo mejoras o bien empeoró. El análisis de los estudios permite concluir que el masaje es una terapia efectiva en el tratamiento del dolor muscular tardío.

Objectives. The aim of this study was to explore the effects of laser acupuncture on improvement of recovery and muscle performance in delayed muscle soreness (DOMS) when applied before exercise. Methods. This randomized, blinded, and controlled study included healthy participants (n = 40) who were randomized into laser acupuncture and placebo groups. Laser acupuncture was applied to the Tianquan (PC2) and Chihtseh acupoints (LU5) at a dose of 36 J and energy density of 9.7 J/cm2 before inducing DOMS. The placebo group received sham laser acupuncture with no laser output. Visual analog scale (VAS), proprioception, pressure pain threshold (PPT), arm circumference, and muscle strength were observed at the baseline and 24, 48, 72, and 96 h after induction of DOMS. Results. Significant changes in the VAS (F4,  43.96 = 31.47; p = 0.001), PPT (F4,  1.35 = 35.07; p = 0.001), normalized arm circumference (F4,  0.001 = 3.87; p = 0.005), and normalized muscle strength (F4,  0.31 = 24.99; p = 0.001) were observed within the groups over time (p < 0.05), but there were no significant differences between the two groups (p > 0.05). Normalized arm circumference was significantly different between the two groups at 48 and 72 h after induction of DOMS (p < 0.05). Conclusion. Photobiomodulation therapy on Tianquan (PC2) and Chihtseh acupoints (LU5) before the exercise did not significantly decrease DOMS and increase muscle performance. Laser acupuncture as a supplemental therapy seemed to have no effect on DOMS prevention.
