Task: Question Answering
Input (English): Context: The aim of the present study was to determine the effect of moderate aerobic exercise on cardiac autonomic function in type 2 diabetic patients.', 'Heart rate variability of 20 patients with type 2 diabetes was assessed. Resting electrocardiogram for the heart rate variability analysis at spontaneous respiration was recorded for 5\xa0min in the supine position before and after 6\xa0months of supervised aerobic training given three times per week.', 'In time domain measures, the square root of the mean of the sum of the squares of differences between adjacent R-R intervals (RMSSD; 29.7 [26-34.5] vs 46.4 [29.8-52.2]\xa0ms, P\xa0=\xa00.023) and the percentage of consecutive RR intervals that differ by more than 50\xa0ms (pNN50; 10.7 [5.5-12.7] vs 26.1 [6.6-37.2]%, P\xa0=\xa00.025] were significantly increased after exercise. In frequency domain measures, low frequency (62.4 [59.1-79.2] vs 37 [31.3-43.3]\xa0nu, P\xa0=\xa00.003) and low frequency/high frequency (1.67 [1.44-3.8] vs 0.58 [0.46-0.59]%, P\xa0=\xa00.009) were significantly decreased, whereas high frequency (95 [67-149] vs 229 [98-427]\xa0ms(2), P\xa0=\xa00.006) and high frequency (37.6 [20.8-40.9] vs 63 [56.7-68.7]\xa0normalized units, P\xa0=\xa00.003) were significantly increased after exercise. In a Poincaré plot, standard deviation perpendicular to the line of the Poincaré plot (SD1; 21.3 [18.5-24.8]-33.1 [21.5-37.2]\xa0ms, P\xa0=\xa00.027) was significantly increased after exercise.\Question: Does mild-to-moderate intensity exercise improve cardiac autonomic drive in type 2 diabetes?
Output (English): These data suggest that three times per week moderate intensity aerobic exercise for 6 months improves cardiac rhythm regulation as measured by heart rate variability in type 2 diabetic patients.
