New research published in Nature Communications indicates that resistance training boosts a myokine called CLCF1, which promotes muscle strength and bone density while reducing aging effects. This study contrasts the effectiveness of cardiovascular exercise, which does not significantly elevate CLCF1 in older adults. In younger individuals, both resistance and high-intensity training effectively increase CLCF1 levels. The findings underline the essential role of resistance training in older adults to activate CLCF1 and promote longevity, suggesting strength training should be prioritized as one ages.
CLCF1, released during resistance training, acts as a youth-boosting myokine that helps in building muscle strength, preserving bone density, and promoting longevity.
While cardiovascular exercise does have various benefits, it does not effectively activate CLCF1 in older adults, indicating the necessity of strength training for this demographic.
