When you exercise – especially as part of a training program – changes occur in your muscles that can ultimately make you faster, stronger, and fitter. Did you know that those changes actually happen within the cells of your muscles? In a new clinical study, MitoQ has been shown to help this process and improve athletic performance.
In a gold-standard clinical trial (i.e., randomized, double-blind, and placebo-controlled) run by the University of Auckland in New Zealand, a group of 23 middle-aged men with no regular training activity were given either MitoQ or a placebo for ten days before completing a HIIT (high-intensity interval training) workout on an exercise bike. Blood samples and thigh muscle tissue were collected from the study participants before they began their workout, directly afterward, and then three hours later.
Researchers found that after HIIT exercise, the participants given MitoQ had higher increases in levels of a co-activator called PGC1α than those given a placebo. PGC1α is a protein or protein complex that activates genetic changes and has been found in other studies to increase after exercise.
After three weeks of HIIT training, participants taking MitoQ® Mitoquinol showed greater increases in peak power - measured by both a VO2peak test and a cycling time trial - compared to those on placebo. The researchers also observed higher levels of PGC-1α in the muscles of the MitoQ® Mitoquinol group, a molecule that plays a key role in signalling the body to produce new mitochondria (more on those below).
What's particularly interesting is where MitoQ® Mitoquinol appeared to make a difference. The improvements were concentrated in high-intensity power output, while aerobic capacity measures remained largely unchanged between groups. This suggests MitoQ may be especially effective at supporting the aspects of performance most sensitive to oxidative stress during intense effort - think peak power and high-intensity output - rather than acting as a broad performance enhancer across the board.
Researchers also put forward alternative mechanisms worth noting: MitoQ® Mitoquinol may support improved blood delivery to working muscles, or directly enhance energy production within the mitochondria itself, both of which could contribute to the power and endurance improvements observed.
MitoQ® Mitoquinol appears to work with the training process, potentially enhancing the responsiveness to high-intensity training stimuli, particularly in people who are in the early phases of a new programme or ramping up their training load.
Overall, the researchers concluded that the results seen with MitoQ® Mitoquinol went beyond what would be expected from regular antioxidant supplements - a finding that aligns with MitoQ's unique ability to accumulate directly inside the mitochondria, rather than acting systemically like vitamin C or standard CoQ10.
As you may know, your cells are powered by your mitochondria. While they work to keep our body functioning, mitochondria also produce a potentially damaging by-product: free radicals. If produced in excess quantities, free radicals can build up and cause cell stress, which compromises cell health and performance. But when they’re produced in healthy amounts, free radicals have a vital role to play in cell-to-cell communication, known as “cell signaling.” Maintaining this delicate balance is important for cell health, and therefore muscle performance.
Exercise training can increase the production of free radicals, so athletes commonly take antioxidant to prevent this build-up from having damaging effects. However, regular antioxidant supplements like vitamin C or E - which aren’t targeted to the mitochondria - can be too indiscriminate and therefore upset the delicate balance of ideal versus harmful levels of free radicals in cells. It’s thought that non-targeted antioxidants may even reduce some of the beneficial effects of exercise.
Because MitoQ® Mitoquinol is a mitochondria-targeted antioxidant (it's one of the world’s first to be able to get into mitochondria, to better help equalize the ratio of antioxidants to free radicals and combat cell stress), it is more able to help cells maintain this delicate but vital balance of good versus harmful levels of free radicals within cells.
In addition to previous studies showing MitoQ® Mitoquinol’s benefits in athletic performance and recovery (including one that showed MitoQ improved 8km time trial performance in trained cyclists), this latest study by the University of Auckland demonstrates the beneficial effects on cellular responses within muscles.
Because the co-activator PGC1α is involved in producing new mitochondria4 and helps with creating a healthy balance of free radicals within cells5, MitoQ® Mitoquinol’s ability to increase its levels is a breakthrough in sports science.
What these findings tell us is that including MitoQ® Mitoquinol within an athlete’s training program can help to increase peak power more than would be possible without MitoQ it. These exciting findings attest to MitoQ’s functional benefits when it comes to exercise.
Without a doubt, it’s a study that will be of huge interest to athletes and consumers alike who are looking to enhance their overall physical performance.
