“…The repeated measurement of ANS activity along with other conditions associated with ANS activity levels, such as physical activity [62,63] , diseases including hypertension [64][65][66][67] , orthostatic hypotension [68][69][70] , and its biological markers [71] , sleep-related breathing disorders, diabetes mellitus, obesity, and the inflammatory status will provide a unique opportunity to describe the chronology of predictors and events. Consequently, the assessment of the inflammatory status is of particular importance as it may be a major factor of ANS activity alteration as neural control of inflammation is reflexive, directly interconnected and controllable [72] .…”

Background: Transversal studies have underlined the association between the decline in autonomic nervous system (ANS) activity and all-cause mortality. However, the predictive value of ANS has never been prospectively assessed in a general population-based cohort. Method: The PROOF (PROgnostic indicator OF cardiovascular and cerebrovascular events) cohort study was designed to prospectively assess the predictive value of ANS activity level in the general population, with regard to cardiovascular and cerebrovascular events, and death. This predictive power will be compared with the usual and newly discovered risk factors for the purposes of developing a risk model. Results: A prospective cohort of elderly subjects aged 65 years upon study entry were recruited from the electoral list of the city of Saint-Etienne, France. Three initial 2-year examination programs were scheduled for 7 years (2001–2007), followed by late events monitoring. At each examination, ANS activity was assessed along with clinical and biological cardiovascular risk factors, brain MRI, neuropsychological evaluation, physical activity profile, and sleep-related breathing disorders. The main study outcomes are stroke, myocardial infarction and death from any cause. A cohort consisting of 1,011 subjects aged 65.6 (0.8) years was constituted. Conclusion: Despite other selective characteristics, the associations between ANS activity and events will be applicable to other populations.

“…However, its effect on HRV after aerobic training programs and the expected positive correlation between higher levels of aerobic fitness and HRV remains controversial. Studies have shown that older adults engaged in physical activity for several years have higher levels of HRV than sedentary ones [12][13][14] . On the other hand, there is evidence that aerobic training programs do not exert significant influence on HRV indices in middle-aged individuals 5,15 -17 .…”

“…Furthermore, this type of protocol may be used for submaximal intensity evaluation by non-medical health care professionals, as it does not produce maximum stress, decreasing the potential for cardiovascular events. Therefore, the discontinuous protocol can be an alternative to the prescription of physical activity in healthy subjects 12,13 and patients with pathologies 14 .…”

| Background:The analysis of the kinetic responses of heart rate (HR) and oxygen consumption (VO 2 ) are an important tool for the evaluation of exercise performance and health status. Objectives: The purpose of this study was to investigate the effects of aging on the HR and VO 2 kinetics during the rest-exercise transition (on-transient) and the exercise-recovery transition (off-transient), in addition to investigating the influence of exercise intensity (mild and moderate) on these variables. Method: A total of 14 young (23±3 years) and 14 elderly (70±4 years) healthy men performed an incremental exercise testing (ramp protocol) on a cycle-ergometer to determine the maximal power (MP). Discontinuous exercise testing was initiated at 10% of the MP with subsequent increases of 10% until exhaustion. The measurement of HR, ventilatory and metabolic variables and blood lactate were obtained at rest and during the discontinuous exercise. Results: The lactate threshold was determined in each subject and was similar between the groups (30±7% of MP in the young group and 29±5% of MP in the elderly group, p>0.05). The HR and VO 2 kinetics (on-and off-transient) were slower in the elderly group compared to the young group (p<0.05). Additionally, in the young group, the values of HR and VO 2 kinetics were higher in the moderate compared to the mild exercise intensity. Conclusion: We concluded that the elderly group presented with slower HR and VO 2 kinetics in relation to the young group for both on-and off-transients of the dynamic exercise. Moreover, in the young group, the kinetic responses were slower in the moderate intensity in relation to the mild intensity.Keywords: aging; exercise; kinetics; blood lactate; physical therapy; rehabilitation.

Objetivos: Investigar o efeito do envelhecimento na resposta cinética da FC e do VO2 durante as transições repouso-exercício (fase-on) e exercício-recuperação (fase-off), além de verificar a influência da intensidade do exercício (leve e moderada) sobre os parâmetros cinéticos dessas variáveis. Método: Catorze homens jovens (23±3 anos) e 14 homens idosos (70±4 anos) aparentemente saudáveis realizaram um teste de esforço incremental tipo rampa em cicloergômetro para determinar a potência máxima (PM) e um teste de exercício descontínuo, iniciado a 10% da PM com aumentos subsequentes de 10% até a exaustão. Foram registradas a FC, as variáveis ventilatórias e metabólicas e da lactacidemia em repouso e durante o exercício descontínuo. R...

Interval training in elderly men increases both heart rate variability and baroreflex activity

Abstract: Intensive endurance training in elderly men enhanced parasympathetic parameters of HRV and, interestingly, of SBR. Physiological mechanisms and long-term clinical effects on health status should be further investigated.
