Protein shakes | The better military food
When fresh army recruits start their first training, protein supplementation helps them to get leaner, and probably also increases their development of muscle strength. Exercise scientists, affiliated with Auburn University in the US, report this in Nutrients.
The researchers experimented with 69 new recruits, all of whom started their army initial entry training. The researchers divided the recruits into 2 groups, and gave one group 2 shakes with whey [WP] for 8 weeks each day. Each shake contained 39 grams of protein, plus some carbohydrates.
The other group received 2 shakes with carbohydrates [CHO] daily. The shakes with carbohydrates yielded as much energy as the protein shakes: 580 kilocalories per day.
Both groups gained as much fat-free mass [read: muscle mass]. However, the soldiers in the whey group lost significantly more body fat.
Both groups became fitter and stronger. The recruits' endurance increase, and after 8 weeks of training the recruits were able to make more sit-ups. There was no difference between the groups. However, the number of push-ups that the soldiers were able to make, increased significantly more in the whey group.
