The turmeric plant, a member of the ginger family, has been used as a spice or food dye in cooking for thousands of years. A yellowish or reddish - depending on the species - substance is obtained from its stem to form one of the main ingredients of curry, a type of dish hailing from Asia that enjoys widespread popularity all over the world. Aside from its uses in cooking, turmeric and its active component, curcumin, are often used in a range of treatments rooted in traditional Asian medicine.
In fact, hundreds of studies have been carried out in recent decades examining the properties of this substance, its effects on the body and the benefits associated with its consumption. Now, researchers in the Epi4Health group at the Universitat Oberta de Catalunya (UOC) have found that turmeric and its related products, such as curcumin, may be able to reduce muscle damage and inflammation in the musculoskeletal system following vigorous physical exercise. "Both pre- and post-exercise curcumin consumption are associated with better outcomes in terms of muscle recovery, reduced pain and improved antioxidant capacity", said Daniel Vasile Popescu-Radu.
He is a pharmacist and nutritionist who is simultaneously studying for a doctoral degree in Health and Psychology and a Master's Degree in Food for Physical Exercise and Sport at the UOC. He is the lead author of the article, developed under the supervision of his tutor Patricia Martínez, a dietician and nutritionist and course instructor at the UOC's Faculty of Health Sciences, and alongside the experts Laura Esquius de la Zarza, a member of staff at the Faculty of Health Sciences and director of the University Master's Degree in Food for Physical Exercise and Sport, and Marta Massip, a member of the same faculty. Hundreds of scientific studies have demonstrated the benefits and potential of curcumin, particularly as regards its properties.
In fact, this supplement is well-known for its antioxidant and anti-inflammatory properties. However, the experts' novel contribution is the confirmation of these findings in the realm of sports through a review of the scientific literature, which was recently published in open access in the Journal of the International Society of Sports Nutrition. The aim of this study was to assess the scientific evidence regarding the effectiveness of curcumin in mitigating exercise-induced muscle damage, such as injuries to muscle fibres, pain and reduced strength, and establish its ability to lower inflammatory markers, improve pain perception and speed up muscle recovery when consumed by trained participants.
" Daniel Vasile Popescu-Radu, pharmacist and nutritionist "The effective use of curcumin is contingent upon factors such as dosage, bioavailability and time of consumption" Benefits of curcumin According to the authors, the possible benefits of curcumin include mitigating and combating various issues, such as local muscle inflammation and systemic inflammation, as well as oxidative damage resulting from the increased production of free radicals during physical exercise and muscle pain, thus improving the individual's subjective perception of pain and the affected muscle group's range of movement. "Moderate curcumin intake within the established post-exercise dosage range helps improve and speed up muscle recovery," said Popescu-Radu, who also explained that "there's always room for professional supervision, as an expert can adjust the dosage and timing of intake to optimize its benefits."

"The effective use of curcumin is contingent upon factors such as dosage, bioavailability and time of consumption, with the most significant benefits seemingly resulting from post-exercise consumption," said Martínez. Absorption and patient profile However, despite these proven benefits, the experts emphasized that factors that must be taken into account include hormonal effects and individual patient or consumer characteristics, as well as the time of intake and the exact formulation used. "The absorption and bioavailability of curcumin may be affected by the formulation used or the presence of other substances, such as piperine.
Furthermore, the varied makeup of the participants in the studies makes it very difficult to extrapolate these results to female athletes or to specific circumstances, such as perimenopause and menopause," said Popescu-Radu. The experts cautioned that, although all these studies show the potential of turmeric as a supplement for athletes, further research, with larger samples, is required in order to confirm and consolidate these findings. "Curcumin could greatly enhance the well-being of those who engage in regular physical training.
It may even play a significant role in reducing inflammation biomarkers and improving antioxidant capacity, among other health benefits," they concluded, while warning that further research into formulation, absorption, bioavailability and other factors remains necessary to properly evaluate the effects described.
