Different Order of Concurrent Training on Improving Visceral Adipose Tissue and Insulin Resistance.

Plain-language summary

Purposes: The purpose of one-year project is to compare the effect of different intrasession exercise order of AE and RE during concurrent training on reducing VAT and improving insulin resistance for inactive middle-age community residents with obesity. Methods: Purposive sampling will be used to enroll community residents aged 40-64 years with inactive habit and body fat percentage ≧ 25% for male and ≧ 30% for female in southern Taiwan. Eligible participants will be stratified by sex and age (40-55years and 56-64 years) then block randomly divided into training group of AE preceding RE, RE preceding AE or a control group. The exercise training program will under supervision lasting 16 weeks with 3 times per week. The concurrent training prescription consist of AE 30 minutes and RE 15 minutes per session. A 5-minute interval between two exercise modalities. All participants will be evaluated outcomes for two time points including baseline (T0) and after 16-week intervention (T1). The primary outcomes are VAT and insulin resistance. A two-way ANOVA with repeated measures will be performed to compare changes of outcome variables over the intervention period. Relevance to clinical practice: The results of this project can assist health professionals to know how to properly prescribe concurrent training of AE and RE to achieve the greatest effects on VATreduction and insulin resistance improvement for middle-age residents with obesity.
