Comparative effects of combined aerobic exercise-based interventions on metabolic, cardiovascular, and inflammatory markers in adult men: a systematic review and meta-analysis.

Plain-language summary

This systematic review and meta-analysis looked at how combining aerobic exercise with other interventions affects metabolic, heart, and inflammation markers in men. It pooled data from 14 randomized controlled trials involving 369 men, comparing aerobic exercise plus extras like resistance training or supplements against control groups. The study found that these combined approaches were linked to lower BMI and improved cholesterol levels, but results varied widely between studies and no clear effects were seen on blood pressure or inflammation markers like IL-6. The authors note that the mixed designs and small samples make it hard to pin benefits to any single part of the combined routines.

Key findings

• Combined aerobic exercise interventions were linked to lower BMI (-1.53 on average).
• Higher HDL (good cholesterol) and lower LDL (bad cholesterol) and total cholesterol were seen with these interventions.
• No clear effects on blood pressure, triglycerides, or inflammation markers like IL-6.
• High variability between studies makes it hard to attribute benefits to specific intervention parts.
