Measuring calorie burn alone not enough, says research

MEASURING the calories burned in a workout alone is not enough, according to new research.
The New Zealand study – published in the Journal of Science and Medicine in Sport – showed that certain types of exercise can trigger far greater fat-burning and other healthy responses in the body than simple calorie counting suggests.
The results fundamentally challenge the way we think about calories. They demonstrate that different workouts have different effects on the hormonal and physiological changes that take place in people’s bodies, even if they burn the same number of calories.
Conducted by researcher Nigel Harris of Auckland University of Technology, the study aimed to identify the underlying causes of clear differences in body fat reductions resulting from resistance training – in the form of Les Mills BODYPUMP – compared to more intense cardiovascular workouts, that an earlier study had shown.
By comparing the levels of Human Growth Hormone (HGH) present in subjects after they had completed resistance training and cardio cycling workouts, it was shown that HGH was 56 percent higher after resistance training.
Head of research for Les Mills International Bryce Hastings said: “Human Growth Hormone oxidises fat and builds lean muscle tissue. That’s important for ongoing calorie expenditure because muscle burns more calories than fat. The more muscle you can build, the more calories your body will burn long-term. Combine that with increased fat loss and the result leads to rapid changes in body composition.
Overall, says Bryce, the study points to how much more people need to know about the effects of certain exercise types.
He added: “It’s complex and just counting calories misses a big part of the jigsaw. We now know that.”
