Short bursts of high intensity training are better for weight loss than longer sessions in the gym, research shows.
Interval training – which involves alternating high intensity and low intensity effort – throws more pounds than a workout that is of the same moderate intensity throughout the experts found.
Fast sprint appeared to have the most profound effect on weight loss, although all high intensity training was good, according to the study published online by the British Journal of Sports Medicine. 1
But the researchers said few people found the time, so they looked at 36 existing studies on interval training involving 1,012 people.
The studies included high intensity interval training (HIIT) with various exercises and sprint interval training that includes running, jogging, speed and cycling.
The results showed that both interval training and continuous training reduced overall weight and percentage of body fat.
Although both approaches helped reduce the percentage of body fat to the same extent, interval training was better for shedding pounds.
Interval training gave a total overall reduction of 29% with 1.58 kg (3.5 lb) compared to 1.13 kg.
The experts from universities in Brazil and the School of Sport, Health and Social Sciences in Hampshire said: "Interval training is an attractive alternative to solving overweight and obesity given its potential to offer benefits similar to moderate intensity continuous exercise while there required less time. "
But they said people should take care as interval training" can increase the risk of injury and impose higher cardiovascular stress ".
