This systematic review and meta-analysis aim to analyze the effects of ingesting non-steroidal anti-inflammatory drugs (NSAIDs) on physical performance, muscle strength, and muscle damage in three different moments: immediately, 24 and 48 h after resistance exercise practice. Relevant studies were researched in three databases (PubMed, Web of Science and SPORTDiscus) in April 2023. After excluding duplicates, the decision to include or exclude studies was made by two independent investigators in the following steps: (I) the study title; (II) the study abstract; and (III) the complete study manuscript. The following characteristics were recorded: (I) first author, (II) year of publication, (III) sample size, (IV) method of NSAIDs administration, (V) exercise protocol, and (VI) analyzed variable results. The studies selected were divided into trials that evaluated the effects of NSAIDs ingestion on performance indices of resistance exercise, endurance exercise and resistance training. The meta-analysis, based only on resistance exercises, revealed that both performance and muscle strength were similar between placebo or NSAID treatment immediately and 24 h after resistance exercise practice. An ergolytic effect was found 48 hours after resistance exercise (mean effect size (ES) = −0.42; 95% CI: −0.71, −0.12; p = 0.132), as well as reduced muscle strength (ES = −0.50; 95% CI: −0.83, −0.16; p = 0.072). Additionally, NSAID use did not prevent muscle waste as seen by the unchanged CK plasma concentration at all timetables. The data of the present meta-analysis indicate that NSAID use is ineffective in improving resistance performance and muscle strength, as well as exercise recovery. When considering the practical application of using NSAIDs to improve exercise capacity and strength gains, the present data supports that consumption of analgesic drugs as an endurance performance enhancer or as a muscle anabolic must not be recommended.

Background: The present study aimed to analyze the effects of exercise-based cardiac rehabilitation (CR) on physical performance after myocardial revascularization. In addition, we compared the type and duration of exercise-based CR protocols to determine which ones produced the best performance improvements. Methods: This systematic review and meta-analysis was conducted and reported in accordance with PRISMA statement. A systematic search of PubMed, Web of Science, SPORTDiscus and ProQuest, was performed in July 2020. Studies that met the following criteria were included: (i) participants submitted to myocardial revascularization (i.e., coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI)), (ii) participants submitted to exercise-based CR, and (iii) participants submitted to protocols for assessing physical performance before and after the exercise-based CR. Results: Thirteen and eleven studies evaluating the effects of exercise-based CR after myocardial revascularization were included in the systematic review and meta-analysis, respectively. Exercise-based CR increased physical performance after myocardial revascularization (mean effect size (ES) 0.75; 95% confidence interval (CI) 0.62, 0.88), particularly when aerobic (ES 0.85; 95% CI 0.68, 1.01) and combined training (ES 1.04; 95% CI 0.70, 1.38) lasting 8-12 weeks (ES 1.20; 95% CI 0.87, 1.53) was prescribed. Conclusions: The present systematic review and meta-analysis indicates that exercise-based CR increases physical performance after myocardial revascularization. The prescription of physical training for these patients should emphasize aerobic and combined training lasting at least 8-12 weeks, which is more effective in improving physical performance. Impact: Our findings demonstrate the effectiveness of physical training in improving physical performance after myocardial revascularization. [ABSTRACT FROM AUTHOR]
