Exercise acts as a non-pharmacological intervention that counteracts age-related insulin resistance by enhancing mitochondrial oxidative capacity, improving autophagy, and reducing oxidative stress and inflammation.
Regular exercise is one of the most effective ways to combat age-related insulin resistance. It improves your muscles' ability to use energy, clears out cellular waste, and reduces inflammation, keeping your insulin sensitivity high.
GoodSupportsHIGH confidence
Exercise can also enhance mitochondrial oxidative capacity, enhance skeletal muscle autophagy and antioxidant capacity, reduce oxidative stress and inflammation levels, and improve skeletal muscle insulin resistance.

More from this paper
- Skeletal muscle aging independently increases the risk of insulin resistance through a convergence of mitochondrial dysfunction, intramyocellular lipid accumulation, chronic inflammation, oxidative stress, and sarcopenia.Moderate
- Mitochondrial dysfunction in aging skeletal muscle, characterized by reduced oxidative capacity and increased ROS production, directly impairs insulin signaling and promotes insulin resistance.Moderate
- Intramyocellular lipid (IMCL) accumulation, specifically the buildup of ceramides and diacylglycerol (DAG), impairs insulin signaling by activating inflammatory pathways and interfering with Akt activity.Moderate
