Μια ενδιαφερουσα μελετη η οποια συγκρινει τις επιδρασεις συμπληρωσης με ορο γαλακτος vs placebo, πριν και μετα την ασκηση με βαρη.

Ο λογος για τον οποιο γραφω οτι ειναι ενδιαφερουσα ειναι οτι ενω το group που λαμβανε ορο γαλακτος ειχε μικροτερη συνολικη ημερησια ποσοτητα πρωτεινων στη διατροφη σε συγκριση με το placebo group, ειχε παρομοια αποτελεσματα σε μυικη περιμετρο, δυναμη και ασκητικο ογκο.

Το συμπερασμα των ερευνητων απο αυτα τα αποτελεσματα ειναι πως η συσταση και ο χρονισμος ληψης πρωτεινων ειναι πιο σημαντικος απο τη συνολικη ποσοτητα αυτων.

Effects of whey protein supplementation prior to, and following, resistance exercise on body composition and training responses: A randomized double-blind placebo-controlled study.

PURPOSE:
The composition of protein supplements, the consumption timing immediately before and after resistance exercise training (RET), and the quantity of protein supplementation may be important factors for the improvement of muscle mass and function. Although these factors should be considered comprehensively for effective improvement of muscular function in protein supplementation, relatively few studies have focused on this area. Therefore, this study was designed to investigate whether a protein blend supplement before and after resistance exercise for 12 weeks would be effective in increasing muscular function.

METHODS:
In total, 18 participants were randomly assigned to a placebo (PLA) or protein blend supplement (PRO) group. All subjects followed the same training routine 3 times per week for 12 weeks, taking placebo or protein supplements immediately before and after each exercise session. The protein supplement consisted of 40 g of blend protein, including hydrolyzed whey protein. The RET consisted of lower body (barbell squat, dead lift, seated leg extension, and lying leg curl) and upper body (bench press, barbell rowing, preacher bench biceps curl, and dumbbell shoulder press) exercises. A repetition was defined as three sets of 10-12 times with 80% of one repetition maximum (1RM).

RESULTS:
Although the PRO group had a lower protein intake in terms of total food intake than the PLA group, the mean changes in muscle circumference, strength, and exercise volume increased, especially at week 12, compared to the PLA group.

CONCLUSION:
These results suggest that the composition and timing of protein intake are more important than the total amount.
