It’s been at the top of our fitness radar since 2014, but could it be time to ditch high-intensity interval training?
Few workouts can match the meteoric rise of high-intensity interval training (HIIT). It’s short and sweet – pairing brief periods of recovery with intervals of exercise performed at near-maximal effort – and has a host of science to back up its effectiveness. Need convincing? Research published in the journal Medicine & Science in Sports & Exercise shows that an eight-week programme of thrice weekly HIIT workouts could result in a 10 per cent greater improvement in aerobic fitness than slow, long-distance training.
Scientists surmise that these results are achieved because the intense activity recruits fast-twitch muscle fibres, which use up lots of fuel, producing powerful bursts of energy. There’s also an ‘after burn’ effect, which sees exercisers continue to use energy after a hard workout, as the body burns calories through replenishing oxygen stores, removing lactate from the muscles and restoring body temperature. The net result is HIIT exercisers boost cardiovascular fitness and may even drop a few pounds.
