Findings from Japan Institute of Sports Sciences Broaden Understanding of Nutritional Science and Vitaminology (Effective Timing of Curcumin Ingestion To Attenuate Eccentric Exercise-induced Muscle Soreness In Men)
Sports Research Daily
2019 APR 26 (NewsRx) -- By a News Reporter-Staff News Editor at Sports Research Daily -- New research on Diet and Nutrition - Nutritional Science and Vitaminology is the subject of a report. According to news reporting originating from Tokyo, Japan, by NewsRx correspondents, research stated, “Curcumin is known to have potent anti-inflammatory effects. We have reported that acute curcumin ingestion attenuates eccentric exercise-induced muscle damage.”
Financial support for this research came from Japan Institute of Sports Sciences.
Our news editors obtained a quote from the research from the Japan Institute of Sports Sciences, “This study aimed to examine the effect of curcumin ingestion timing (before or after exercise) on the changes in muscle damage markers after eccentric exercise. In this randomized, single-blind, parallel design study, 24 healthy young men performed 30 maximal isokinetic (120 degrees/s) eccentric contractions of the elbow flexors using an isokinetic dynamometer. Subjects were randomly assigned to ingest 180 mg/d of oral curcumin either 7 d before (PRE) or 4 d after exercise (POST) or 180 mg/d of oral placebo 4 d after exercise (CON). The maximal voluntary contraction (MVC) torque of the elbow flexors, elbow joint range of motion (ROM), muscle soreness, and serum creatine kinase (CK) activity were measured before, immediately after, and 1-4 d after exercise. Changes in these variables were compared over time. In the POST group, ROM were higher at 3-4 d and muscle soreness was lower at 3 d after exercise compared with the CON group (p <0.05). However, in the PRE group, there were no significant differences compared with the CON group in changes in ROM and muscle soreness. Meanwhile, there were no significant differences among the groups in terms of changes in MVC torque and serum CK activity.”
According to the news editors, the research concluded: “Our results suggest that curcumin ingestion after exercise had a more beneficial effect in attenuating muscle soreness.”
