Cardiac autonomic modulation during progressive upper limb exercise by patients with coronary artery disease BJMBR
Machado,H.G.; Simões,R.P.; Mendes,R.G.; Castello,V.; Di Thommazo,L.; Almeida,L.B.; Lopes,S.L.B.; Catai,A.M.; Borghi-Silva,A..
The purpose of this study was to investigate the behavior of heart rate (HR) and HR variability (HRV) during different loads of resistance exercise (incline bench press) in patients with coronary artery disease (CAD) and healthy sedentary controls. Ten healthy men (65 ± 1.2 years, control group, CG) and 10 men with clinically stable CAD (66 ± 2.4 years, CADG) were recruited. A discontinuous progressive protocol was applied with an initial load of 10% of the maximum load achieved in the 1RM (1 repetition maximum) with increases of 10% until 30% 1RM was reached, which was followed by subsequent increases of 5% 1RM until exhaustion. HRV was analyzed by linear and non-linear methods. There was a significant reduction in rMSSD (CG: 20 ± 2 to 11 ± 3 ms; CADG: 19...

Ultra-short-term heart rate variability during resistance exercise in the elderly BJMBR
Arêas,G.P.T.; Caruso,F.C.R.; Simões,R.P.; Castello-Simões,V.; Jaenisch,R.B.; Sato,T.O.; Cabiddu,R.; Mendes,R.; Arena,R.; Borghi-Silva,A..
Despite the appeal of ultra-short-term heart rate variability (HRV) methods of analysis applied in the clinical and research settings, the number of studies that have investigated HRV by analyzing R-R interval (RRi) recordings shorter than 5 min is still limited. Moreover, ultra-short-term HRV analysis has not been extensively validated during exercise and, currently, no indications exist for its applicability during resistance exercise. The aim of the present study was to compare ultra-short-term HRV analysis with standard short-term HRV analysis during low-intensity, dynamic, lower limb resistance exercise in healthy elderly subjects. Heart rate (HR) and RRi signals were collected from 9 healthy elderly men during discontinuous incremental resistance...
