Body mass squats make teenagers more muscular and slimmer
Sports scientists are in no doubt. Strength training is healthy. But the jury is still out on what the optimal age is for young males to start doing strength training.
Study
The researchers did an 8-week experiment with a group of nearly one hundred boys, all of whom did sports at a high level and trained on average five days a week. Of the group, 58 just kept to their own training – the control group.
The experimental group was made up of 36 boys. Every day after school, 4-6 times a week, the researchers got the boys to do a short squat training session. The boys had to do knee bends with their own weight as the load, for a few minutes. The boys had to squat until their upper legs were parallel with the floor.
They did this at high speed: they did a rep every two seconds, and the aim was to build up to 100 reps without a break.
Results
MTQF = muscle thickness of anterior of thigh.
At the end of the eight weeks the boys in the experimental group were also capable of generating more strength on a leg-extension machine [KES]. Their sprint speed had not increased, but they could jump a centimetre higher.
