Strength training fights belly fat better than aerobic training
Strength training and body fat
On the other hand though: after the age of thirty you lose a little bit of muscle mass each year. Because every kilogram of muscle mass you lose also lowers your daily calorie burning by a couple of dozen kilocalories, the older you are, the more easily you put on weight. You can stop this process by doing strength training. If you train really hard and eat enough protein, you can even build up more muscle mass as you age. Aerobic forms of exercise contribute little to building up more muscle mass.
Study
"Because aging is associated with the loss of skeletal muscle mass, relying on body weight is insufficient for the study of healthy aging", explained Rania Mekary, the first author of the study, in a press release. [harvard.edu December 22, 2014] "Measuring waist circumference is a better indicator of healthy body composition among older adults."
The researchers divided the men up according to the amount of exercise they got. First the researchers looked at the amount of moderate to vigorous aerobic activity [MVAA] the men got daily. The norm is at least half an hour a day of this type of exercise.
Then the researchers looked at the number of minutes a day the men devoted to strength training.
Results
The researchers even calculated that if the participants had done 20 minutes of strength training daily during the 12 years of the study instead of 30 minutes of aerobic activity, they would have lost another 0.34 cm from their waist measurement. It would have been even better if they had done 20 minutes strength training a day instead of of watching TV for 30 minutes: that would have resulted in a reduction of 0.76 cm on the waist measurement.
Conclusion
"This study underscores the importance of weight training in reducing abdominal obesity, especially among the elderly", said Hu. "To maintain a healthy weight and waistline, it is critical to incorporate weight training with aerobic exercise."
