High intensity workout may hurt you if you are new to gym
Have you just joined a gym and already started a high-intensity \"sprint training\" workout? A new study has found signs of stress in the muscle tissues of non-athletes and untrained people after ultra-intense leg and arm cycling exercises which might not be healthy.
Toronto: Have you just joined a gym and already started a high-intensity "sprint training" workout? A new study has found signs of stress in the muscle tissues of non-athletes and untrained people after ultra-intense leg and arm cycling exercises which might not be healthy.
Researchers found untrained people had a weakened ability to fight off free radicals -- molecules that can alter DNA and harm healthy cells -- that may increase the risk of cancer, premature aging and organ damage. Beginners start slowly and gradually increase intensity over time, under the supervision of a trained professional or kinesiologist, the authors suggested.
The researchers analysed tissue samples from their test the participants and found that their mitochondria - the powerhouse of cells - were only firing at half-power post-training, reducing their capacity to consume oxygen and their ability to fight off damage from free radicals. Seasoned athletes and those who are well trained have built up antioxidant enzymes in their bodies to protect against free radicals, said Boushel.
