ABSTRACT
AIMS: This study aimed to evaluate the impact of a 12-week calorie-restricted diet and recreational sports training on gene expressions IL15, ATROGIN1 and MURF-1 in skeletal muscle of T2D patients.
METHODS: Older adults with T2D (n = 39, 60 ± 6.0 years, BMI 33.5 ± 0.6 kg/m2) were randomly allocated to Diet+Soccer (DS), Diet+Running (DR) or Diet (D). The training sessions were moderate-to-high-intensity and performed 3 × 40 min/week for 12-weeks. Gene expression from vastus lateralis muscle obtained by qRT-PCR, dual-energy X-ray and fasting blood testing measurements were performed before and after 12-weeks. Statistical analysis adopted were two-way ANOVA and Paired t-test for gene expression, and RM-ANOVA test for the remainder variables.
RESULTS: Total body weight was reduced in ~4 kg representing body fat mass in all groups after 12-weeks (P < 0.05). HbA1c values decreased in all groups post-intervention. Lipids profile improved in the training groups (P < 0.05) after 12-weeks. ATROGIN1 and MURF-1 mRNA reduced in the DS (1.084 ± 0.14 vs. 0.754 ± 1.14 and (1.175 ± 0.34 vs. 0.693 ± 0.12, respectively; P < 0.05), while IL15 mRNA increased in the DR (1056 ± 0,12 vs. 1308 ± 0,13; P < 0.05) after 12-weeks intervention.
CONCLUSION: Recreational training with a moderate calorie-restricted diet can downregulates the expression of atrophy-associated myokines and increases the expression of anti-inflammatory gene IL15.
