Scientists found a single bicep curl done three times a week significantly improved arm strength. 1 Three seconds of exercise done three days a week could be enough to build muscle, scientists say Credit: Getty The team at Edith Cowan University in Australia last year discovered that doing it five days a week made people stronger . But their latest work looked at the minimum number of days required to reap the benefits. The study, published in the European Journal of Applied Physiology, found three separate occasions was the sweet spot. Co-author Professor Kazunori Nosaka, said: "Our previous work has shown regular, shorter exercise is more beneficial than one or two big training sessions in a week. "Now, we have a clearer idea of where the tipping point is where you start to see meaningful benefits from such a minimal exercise." A total of 26 healthy adults participated in the study, which was carried out over a month. Each did a single three-second bicep contraction using their dominant arm, either two days or three days a week. This is similar to slowly lowering a heavy dumbbell, from a bent arm to a straight arm. Those who performed the move twice weekly saw no significant changes. But the three-day-a-week group saw a small but significant increase in concentric strength (2.5 per cent) and eccentric strength (3.9 per cent). Eccentric (or muscle lengthening) movement occurs as you slowly lower your arm down towards your waist during a bicep curl. Curling your arm back up to your shoulder is a concentric (or muscle shortening) movement. "These new results suggest at least three days a week are required, at least for the single three-second eccentric contraction training," Prof Nosaka said. But he was keen to point out that five times a week provided the biggest boost, with a 10 per cent increase noted in both categories, as well as isom){kind=link}
