The resistance training programs lasted 6 to 38 weeks, with 2 to 3 weekly sessions. The exercises included squats, leg presses, bench presses, and rows, performed at 30% to 85% of 1-repetition maximum (1RM) for 1 to 5 sets of 4 to 25 repetitions. The training methods used elastic bands, body weight, free weights, or machines.
Overall, resistance training reduced CRP levels with a moderate-to-large effect size, and interleukin 6 and TNF-alpha remained unchanged. Resistance training also improved walking speed and leg extension strength and reduced body fat percentage.
Resistance training likely reduced CRP by lowering chronic low-grade inflammation, possibly through improved muscle function,[1] increased release of anti-inflammatory cytokines,[2] and reductions in body fat, especially visceral fat (a key driver of inflammation).[3] However, interleukin 6 and TNF-alpha remained unchanged, likely because interleukin 6 has both proinflammatory and anti-inflammatory roles, whereas TNF-alpha is associated with short-term rather than long-term inflammation.
