“…16,18 There is an interest in the postmenopausal period, and thus some studies included volunteers who were under 60 years old. In the studies by Jurca 19 and other studies support the theory that aerobic exercise training can alter neuroregulatory control over the heart in both genders. 19 AT can increase CBS in sedentary middle-age and older men in a 3 month period using the type (primarily walking), frequency, and intensity the exercise that middle-age and older men are able to perform.…”

Cardiovascular autonomic markers such as cardiovagal baroreflex sensitivity (CBS) and heart rate variability (HRV) decline with the aging process. Aerobic training (AT) may be able to improve HRV, suggesting that AT can alter neuroregulatory control over the heart, improving autonomic markers and cardiac protection. Together, age and AT can influence HRV, but not revert the overall effects of aging on the decline of physical performance and HRV. The aim of this study was to review studies and describe the volume of AT necessary to produce modifications in HRV in elderly individuals. The review followed the guidelines of the Preferred Reporting Items for Systematic Reviews and MetaAnalysis (PRISMA). The articles selected were indexed in PubMed/MEDLINE, Lilacs and Scopus. The used keywords were "aging", "heart rate variability", "exercise" combined with the Boolean descriptors "AND" and "OR" with the synonyms "elderly", "cardiac autonomic modulation", "aerobic training" and "endurance training". The filters "languages", "humans", "age" and "clinical trial" were applied in the selection of the articles. Initially, 940 articles were found, PubMed (n = 729), Lilacs (n = 16) and Scopus (n = 195), filters and searches led to the 287 potential studies. The keyword combinations provided 24 articles that were in agreement with the inclusion criteria, and after full reading of the texts, 17 studies were excluded. From seven articles, four showed increases in HRV in response to AT. In an older population, 8 weeks of AT is enough to induce positive changes on HRV. However, longer exercise protocols and higher intensities also seem to have some influence.

“…Detailed descriptions of each of the 14 studies are outlined in Table 1. In cases where multiple publications investigated the same population of subjects, the most appropriate publication was reviewed [22][23][24][25][26][27]. In all tables thereafter (Tables 2, 3, and 4), relative efficacy of eccentric exercise is described using percent change from baseline within groups.…”

“…Isokinetic strength training and assessment were used in three of the 14 studies [26,33,34]. Eccentric-only training of the ankle dorsiflexors in an upright position produced significant improvements in eccentric ankle dorsiflexion peak torque (17 %) after an 8-week intervention [33].…”

Eccentric exercise has gained increasing attention as a suitable and promising intervention to delay or mitigate the known physical and physiological declines associated with aging. Determining the relative efficacy of eccentric exercise when compared with the more conventionally prescribed traditional resistance exercise will support evidence-based prescribing for the aging population. Thus, original research studies incorporating chronic eccentric exercise interventions in the older adult population were included in this review. The effects of a range of eccentric exercise modalities on muscular strength, functional capacity, body composition, muscle architecture, markers of muscle damage, the immune system, cardiovascular system, endocrine system, and rating of perceived exertion were all reviewed as outcomes of particular interest in the older adult. Muscular strength was found to increase most consistently compared with results from traditional resistance exercise. Functional capacity and body composition showed significant improvements with eccentric endurance protocols, especially in older, frail or sedentary cohorts. Muscle damage was avoided with the gradual progression of novel eccentric exercise, while muscle damage from intense acute bouts was significantly attenuated with repeated sessions. Eccentric exercise causes little cardiovascular stress; thus, it may not generate the overload required to elicit cardiovascular adaptations. An anabolic state may be achievable following eccentric exercise, while improvements to insulin sensitivity have not been found. Finally, rating of perceived exertion during eccentric exercise was often significantly lower than during traditional resistance exercise. Overall, evidence supports the prescription of eccentric exercise for the majority of outcomes of interest in the diverse cohorts of the older adult population.

Skeletal muscle mass, strength, and function decline with aging are the symptoms that characterize sarcopenia, which has become a significant problem in aging societies. Aging is also associated with arterial stiffness and autonomic nervous dysfunction, leading to increase in the risk of cardiovascular disease (CVD) and mortality. Resistance training (RT) is effective for improving muscle fitness in older individuals as well as young healthy individuals. However, the effects of RT on autonomic nervous function (ANF) in the elderly have not been fully elucidated. The author reviewed the current evidence regarding RT and ANF in older individuals. Whole-body, high-intensity or progressive RT had either no effect on ANF or perhaps an unfavorable effect on ANF. On the other hand, local isometric, moderate-intensity RT may have a beneficial effect on ANF in older individuals. The combination of RT and aerobic exercise had a favorable effect on ANF in older patients with comorbidities. However, the optimal intensity, frequency, and duration of RT for improving ANF in older individuals remain unknown. Further studies with a large number of subjects are warranted.
