The Claim

Aerobic training results in the largest reduction in TNF-α levels compared to resistance training and combined training in older adults with frailty or sarcopenia, with a standardized mean difference of -0.42 (95% CI: -0.79 to -0.06, p = 0.022).

In plain English

In older adults with frailty or sarcopenia, aerobic exercise lowers the inflammatory marker TNF-α more than resistance training or combined training.

See the scientific wording

Aerobic training produces the largest reduction in TNF-α among exercise modalities in older adults with frailty or sarcopenia, with a standardized mean difference of -0.42 (95% CI: -0.79 to -0.06, p = 0.022), suggesting it may be more effective than resistance or combined training for targeting this specific inflammatory marker.

Why this might work

Aerobic exercise burns fat around the organs, which stops that fat from releasing a harmful inflammatory signal called TNF-α. At the same time, it makes muscles release a different signal called IL-6 that blocks immune cells from making more TNF-α. It also reduces stress and damage in muscle tissue, which stops immune cells from getting activated and spilling TNF-α into the blood.

  1. Study: Effects of exercise interventions on inflammatory biomarker levels in older adults with frailty and/or sarcopenia: a systematic review and meta-analysis

    This study found that in older adults with muscle weakness, walking or cycling lowered a harmful inflammation marker (TNF-alpha) more than weight training or mixing both types of exercise. So yes, aerobic exercise seems to be the best for reducing this specific inflammation.
