Abstract	Purpose: In a cross-sectional study design, we evaluated the resting heart rate (HR[subscript baseline]) and exercise and postexercise stress test-related chronotropic responses in male practitioners of recreational ballroom dancing (BD; n = 25, M[subscript age] = 26.6 ± 6.1 years) compared to a control group of insufficiently active nondancers (CG; n = 25, M[subscript age] = 25.9 ± 4.5 years). Method: All participants underwent a submaximal exercise test. At 85% of the maximal predicted HR, the recovery protocol was started, and heart rate recovery (HRR) was recorded during 1-min intervals for 5 min. Results: Compared with CG, BD showed lower HR[subscript baseline] (70 beats per minute [bpm] vs. 62 bpm, respectively, U = 143, p < 0.05, ES = 0.46), lower preexercise HR (94 bpm vs. 86 bpm, U = 157, p < 0.05, ES = 0.42), longer exercise test duration (346 s vs. 420 s, U = 95.5, p < 0.05, ES = 0.59), and higher HRR for 5 min postexercise (U = 1.29-1.89, p < 0.05, ES = 0.33-0.50) as follows: 1st min (32 bpm vs. 40 bpm), 2nd min (45 bpm vs. 53 bpm), 3rd min (51 bpm vs. 58 bpm), 4th min (55 bpm vs. 59 bpm), and 5th min (59 bpm vs. 63 bpm). The coefficient of HRR from the 1st min to the 5th min postexercise was similar in both groups (U = 229-311, p > 0.05, ES = < 0.10-0.22). Conclusion: Heightened cardiovascular functional status characterized by favorable enhanced chronotropic dynamics appears to occur in practitioners of recreational ballroom dancing, which suggests that this modality of exercise may result in health benefits.
