HMB Supplementation For Endurance Athletes

If you're over 40, your body is starting that downward spiral to muscle breakdown and loss, BUT this doesn't have to be your story.

With age, the response of our muscle tissues to resistance training and the rate of muscle loss can really make building and maintaining muscle mass an uphill battle.

This is why it's important to make resistance training a part of your life. It's another reason to add HMB (hydroxymethylbutyrate) to your fitness routine.

HMB can stimulate muscle protein synthesis because it upregulates anabolic pathways and can minimize muscle protein breakdown via its regulating effects on the catabolic signaling pathways. 

What is HMB?

HMB is a chemical produced from the essential branched-chain amino acid leucine

According to the International Journal of Sport Nutrition and Exercise Metabolism,

HMB supplementation has been shown to reduce proteolysis and muscle-structure damage resulting from an acute bout of eccentric running which are known to limit sport performance.

The Journal of Applied Physiology noted that,

Dietary supplementation of 3.0 g HMB/day in individuals undergoing intense endurance exercise resulted in decreased CPK and LDH responses after a prolonged run. These findings are consistent with the hypothesis that HMB-supplemented subjects experienced less muscle damage or that the HMB-supplemented group could have sustained a similar amount of muscle damage as the placebo-supplemented group but recovered at a faster rate.

The Metabolism Journal concluded that,

HMB improves body composition and sensorimotor function during normal training and attenuates muscle mass and strength loss during catabolic conditions.

If you're over 40 or in an endurance sport, try PRO HMB to help prevent muscle loss and support physical performance.
