Exercise is known to reduce inflammation in various clinical populations; however, its effect on chronic post-burn inflammation remains unclear. This crossover trial investigated the impact of a 6-week exercise intervention on tumour necrosis factor-alpha (TNF-α) in adults with non-severe burns sustained more than one year prior. Methods: Twenty-one participants were randomised to complete either a 6-week exercise program or a control period first, separated by a 4-week washout. The exercise program comprised three supervised sessions per week of combined resistance and cardiovascular training. Primary (TNF-α) and secondary (muscle strength, cardiovascular fitness) outcomes were assessed pre- and post-intervention. Results: Fifteen participants completed the protocol with high adherence (90.4%). Exercise significantly improved quadriceps strength and cardiovascular fitness, confirming the intervention’s safety and efficacy in this cohort. However, TNF-α concentrations were not elevated at baseline and did not significantly change following exercise compared with control (mean difference: +0.5 pg·mL−1, p = 0.249). Exercise is safe and beneficial for non-severely burned patients who sustained their injury > 1 year ago. However, inflammation was not elevated in this cohort, precluding our ability to test the effects of exercise on chronic inflammation.
