Abstract Introduction:<\b>
The heart rate (HR) suffers normal and expected changes, known as heart rate variability (HRV). The HRV indicators have been used to evaluate exercise-related cardiovascular adaptations. This study investigated the effects of the training program with exergames and aerobic exercises on HR and HRV. . Methods:<\b>
Twenty-seven older adults (60.3 ± 3.7 years) completed 12 weeks of training. The training program with exergames (n=13), was conducted using games that simulate sports activities through the Xbox 360 Kinecttm (Kinect Sports Ultimate Collection). The aerobic training program (n=14), cycle ergometers and treadmills, with moderate intensity (40-60% of HR reserve) exercise were used. The HR and HRV indicators were collected at rest and during execution of a battery computerised cognitive assessment “Cogstate Battery” (executive function, psychomotor function, visual attention, short-term memory, working memory and delayed recall), before and after training programs. Results:<\b>
There was no significant difference on HR and HRV indicators during the rest and overall cognitive battery performance, after 12 weeks of training with exergames or with aerobic exercises. The exergames group showed less sympathetic activity during performance in the visual attention test than in resting after training. Participants of the aerobic group presented greater sympathetic activity during the performance in the executive function test than in resting after training. Conclusion:<\b>
The HRV indicators showed a change during the performance of cognitive tests in relation to resting values. However, resting HR and HRV time and frequency indicators (at rest and during cognitive tests) did not change after 12 weeks of training.
