Strength training versus high-intensity aerobic exercise: which is more effective in increasing il-10 production as an anti-inflammatory?

Background and Study Aim. Physical exercise is widely recognized as an effective strategy for improving health and quality of life. The purpose of this study was to analyze the effects of high-intensity and low-intensity strength training, as well as high-intensity aerobic exercise, on serum Interleukin-10 (IL-10) production. Material and Methods. Thirty college students were recruited to undergo different training programs in each group. The study employed an experimental design with three exercise groups: high-intensity strength training (STH), low-intensity strength training (STR), and high-intensity aerobic exercise (AH). Each group included 10 participants, and serum IL-10 levels were measured before exercise and 24 hours post-exercise. To assess long-term effects, participants trained three times per week for four weeks under carefully monitored conditions. Results. The results showed that all types of exercise significantly increased serum IL-10 levels. The AH group exhibited the highest increase, followed by the STR and STH groups. These findings align with previous studies demonstrating an increase in IL-10 following high-intensity aerobic exercise. The elevated IL-10 levels in the AH group can be attributed to improved cardiovascular capacity and the body's inflammatory response. Strength training, despite not increasing VO2max, also led to an IL-10 increase, though the effect was smaller compared to aerobic exercise. Conclusions. High-intensity aerobic exercise is more effective at increasing IL-10 production compared to strength training. This study suggests combining both types of exercise to maximize immunological benefits. Such an approach can also enhance post-exercise recovery. It is important to consider the duration and recovery intervals, as these factors influence the immune response.
