Brief Summary

Introduction: Based on the premise that physical training can provide benefits to the elderly, being able to reduce cardiac and cardiac sympathetic activity and blood pressure and increase cardiac parasympathetic activity, making it pertinent to understand the effects caused by isometric training with handgrip, never studied in this fragile population, to consider whether this type of exercise when performed by the elderly is efficient and safe from an autonomic and hemodynamic point of view. Objective: To evaluate the effect of isometric handgrip training on heart rate variability (HRV) and blood pressure (BP) in frail elderly people. Methods: After screening 509 elderly people from the Integrated Health Center in the city of São Paulo, 36 elderly people (33 women and 3 men) with a mean age of 69±7.36 years, classified as independent elderly according to the criteria of Fried et al. (2001). The elderly were randomized to the isometric training with handgrip (IHT) or control group, for a period of 30 consecutive days. Before and after this period, the RR interval was evaluated using the polar V800 and the HRV was observed using the Kubios HRV Standard. Blood pressure was measured in the remainder, by the auscultatory method. Results: There was a significant reduction after isometric training in the LF (nu) index (p<0.001) and in the autonomic balance (p<0.001), in addition to a significant increase in the HF (nu) index (p<0.001). In the control group, there was no change in HRV in any of the parameters. There was a reduction in SBP only in the TF group (p=0.044), while in the control group there were no changes. There were no changes for DBP or HR in any of the groups, although DBP in the TF group had a tendency to decrease (p=0.059). Conclusion: There was an improvement in HRV after isometric training with a handgrip, with a reduction in sympathetic modulation and an increase in cardiac parasympathetic modulation. Furthermore, isometric training was associated with SBP, which was moderately correlated with increased cardiac parasympathetic modulation in these patients
