1 minute of sprinting and 9 minutes of exercise daily can boost aerobic fitness
Sprinting for a minute along with 9 minutes of light exercise can help achieve same aerobic fitness as a 50 minute exercise, a Canadian study claims. Researchers from McMaster University, Ontario enlisted 25 men who previously did no exercise and randomly assigned them to a sprint interval workout or an endurance workout. Sprint workout included warming up for 2 minutes, sprinting for 20 seconds and recovering for 2 minutes. This was done three times until the participant achieved 1 minute of sprinting. The endurance workout consisted of warming up for 2 minutes, sprinting at a moderate pace for 45 minutes and cooling down for 3 minutes. After 12 weeks the two groups showed similar improvements in aerobic fitness. The study was published in journal PLOS ONE. Read more here.
