Η επίδραση της διατροφικής πρόσληψης πρωτεϊνών στην απόδοση ασθενών με σακχαρώδη διαβήτη τύπου ΙΙ
Translated title:
The effect of dietary protein intake on the performance of patients with type II diabetes mellitus
Summary:
The two-way relationship between sarcopenia and diabetes mellitus triggers a number of negative health consequences for older people. Supplementing the diet with protein, however, seems to help both in maintaining their muscle mass and in regulating glucose. The aim of the present study was to examine the effect of increased dietary protein intake on muscle mass, upper and lower limb muscle strength, anterior and posterior thigh isokinetic torque and functional capacity in older adults with type II diabetes mellitus (non-insulin-dependent). The participants were eleven men (N=11) and eleven women (N=11) (all in the menopausal phase) with an average age of 59,9 + 7,5 years. The sample was randomized into a control group (n1=11), which consumed 0,8 g protein/kgr/day and an intervention group (n2=11), which consumed 1,5 g protein/kg/day) over a duration of 12 weeks. The diets of both groups were isocaloric. Assessments of body composition, muscle strength and functional ability were performed at baseline, at 6th and at 12th week of intervention. Two-factor analysis of variance (2-way ANOVA) with repeated measures over time was used for statistical analysis on all parameters. It was found that by the 12th week only the intervention group increased lean mass while maintained a stable body mass as well as revealed significant improvement in all assessments of functional ability, that is, the time up and go and the 10m Walk tests (p<0. 05). Regarding muscle strength there was no significant effect of dietary intervention in time or between groups. In conclusion, it is clear that dietary higher protein consumption in individuals suffering type II diabetes mellitus (no-insuline-depented) has a positive impact on body composition and functional capacity. Muscular strength does not seem to be affected by the higher protein consumption strictly through diet.
