Researchers at the University of Exeter have conducted a study which reveals that dietary supplements that aid absorption of nitric oxide may allow everyday gym-goers and bodybuilders alike to hit the weights or treadmill for up to 20 percent longer.
The team of scientists said that nitric oxide has been shown to help the body use oxygen more efficiently.
"The research found that when the dietary supplement was used there was a striking increase in performance by altering the use of oxygen during exercise," said Andrew Jones, from the university's School of Sport and Health Sciences.
The researchers looked into the effectiveness of a nitric oxide-boosting supplement after the discovery that beet juice - which is rich in the compound - may significantly improve physical performance.
Nitric oxide works by helping to maintain the flexibility and function of vascular smooth muscle cells, thereby promoting healthy blood flow. Additionally, it has been shown to help repair or prevent vascular damage in a previous mouse study that was conducted at Stanford University.
Results of the study suggest that taking nitric oxide supplements pre-workout may help individuals build muscles and burn fat.
