Moreira Objectives The aim of this study was to investigate the relationship between glucose and heart rate variability (HRV) during 24h after different resistance exercise (RE) intensities in women with type 2 diabetes (T2D). Equipment and methods Twelve women with T2D (55.2±4.0years; 70.1±11.4kg; 155.7±3.3cm) performed experimental sessions divided in two blocks separated by seven days and in a randomized order: block-A (session 1: control–CON40% and session 2: RE at 40% of the one repetition maximum test–1RM) and block-B (session 3: CON80% and session 4: RE at 80%1RM). The glucose and R-R interval (RRi) of HRV were evaluated during 24h every 5min of each experimental session by continuous glucose monitoring system (Guardian/REAL-Time) and cardiofrequencimeter Polar/RS800CX, which generated 288 measurement points for correlation. Pearson's correlation was performed among glucose and RRi values, low frequency (LF), high frequency (HF) and LF:HF ratio. Results Correlations (P <0.01) were found between glucose and RRi, LF, HF and LF:HF for the CON40% (r =−0.60, r =0.38, r =−0.38, r =0.29, respectively) and CON80%1RM (r =−0.50, r =0.28, r =−0.28, r =0.29, respectively). To the 40%1RM were found correlations between glucose and RRi (r =−0.35; P <0.001) and to the 80%1RM between...
