“…The findings of the present study identified different protocols for interventions: IT (Ahmaidi et al, 1998;Pichot et al, 2005;Lepretre et al, 2009;Molmen et al, 2012), Sprint Interval Training (SIT) (Adamson et al, 2019), and the High Intensity Interval Walking Training (HIIWT) (Nemoto et al, 2007). With the advances and popularization of the interval training using different intensities of effort, it was necessary to elaborate on different nomenclatures for this method.…”

“…None of the studies concealed criteria (PEDro scale question 3). Four studies (Ahmaidi et al, 1998;Nemoto et al, 2007;Lepretre et al, 2009;Adamson et al, 2019) showed similarity between groups (PEDro scale question 4).

“…The summary of articles, in Table 2, was based on a structured questionnaire that considered the following items: Authors, year of publication, sampling (amount, gender, and age), training protocols, dependent variable, and results (Neto et al, 2017). In these selected studies, the findings were from publications from 1998 (Ahmaidi et al, 1998) to 2019 (Adamson et al, 2019). Regarding sampling, 251 individuals were found, 107 men and 144 women.…”

Effects of Cardiovascular Interval Training in Healthy Elderly Subjects: A Systematic Review

et al. 2020

The aim of this review is to demonstrate the effects of cardiovascular interval training (IT) on healthy elderly subjects. We used the recommendations of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The following variables were observed: resting heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MBP), heart rate variability (HRV), baroreflex activity (BA), and maximal oxygen uptake (VO 2max). Studies were searched for in the MedLine, PubMed, and Sport Discus databases considering publications between 1990 and 2019. To find the studies, the keywords used were "Interval and Elderly Training" or "Interval Training and Baroreflex Sensing" or "Interval Training and Aging and Pressure Arterial and Blood Pressure Training" or "Interval Training and Variation in Aging and Heart Rate" or "Interval Training and Sensitivity to the Elderly and Baroreflex" or "Interval Training and Variability in the Elderly and Heart Rate." The systematic search identified 1,140 hits. The analysis of the study was performed through a critical review of the content. One thousand one hundred forty articles were identified. Of these, 1,108 articles were excluded by checking the articles and abstracts. Finally, 32 studies were selected for full reading while 26 studies were eliminated because they did not contain a methodology according to the purpose of this review. Thus, six studies were included for the final analysis. The PEDro score was used for analyzing the study quality and found 4,8 ± 1,3 points (range: 3-6). Positive results were found with the different IT protocols in the observed variables. Results show that IT protocols can be an efficient method for functional improvement of cardiovascular and cardiorespiratory variables in the healthy elderly, especially HR, SBP, DBP, MAP, HRV, BA, and VO 2max. However, this method can be included in the prescription of aerobic training for the elderly to obtain conditional improvements in the cardiovascular system, thus being an important clinical intervention for the public.

“…The aerobic stimulus can reduce the plasma level of renin, re ecting in the decrease of the renin-angiotensin system, improving the barore ex activity, consequently the behavior of BP, HR, and HRV 20,31 . The improvement in capillary density, endothelial function and oxygen delivery to tissues, are factors that can in uence hemodynamic and autonomic development 19,54,56 . Concerning VO 2max , successive stimuli combined with periods of recovery, make the elderly manage to impose higher intensities, and this promotes better transport capacity and consumption of O 2 .…”

This study aimed to verify the chronic effects of interval training (IT) with different intensities in the hemodynamic, autonomic, and cardiorespiratory variables of physically active older people. Twenty-four physically active older men (age: 68.8 ± 6.8 years, body mass: 74.4 ± 18.1 kg, height: 170 ± 8 m, body mass index: 25.1 ± 2.2 kg / m²) participated in the study. Participants were randomized into three experimental groups: training group A (TGA, n = 8), training group B (TGB, n = 8), and control group (GC, n = 8). TGA and TGB groups performed 32 training sessions separated by a 48-hour interval. TGA showed 4-min with intensity relative to 55 to 60% of the HRmax and 1-min at 70 to 75% of the HRmax. TGB training group performed the same protocol but performed 4-min at 45 to 50% HRmax and 1-min at 60 to 65% HRmax. Both training groups performed each series for six times, totaling 30-min per session. The evaluations were carried out in the pre (baseline) moments after the 16th and 32nd intervention sessions. GC only carried out assessments. Hemodynamic variables (HRR, SBP, DBP, MBP, and DP), autonomic (HRV indices, in the time and frequency domain), and cardiorespiratory (VO2max estimated) variables were evaluated. There were no statistically significant differences in comparisons between protocols and moments (p>0.05). However, the size of the effect and the percentage delta indicated clinical results with relevant magnitudes between protocols and moments, indicating favorable responses to the IT intervention in hemodynamic, autonomic, and cardiorespiratory variables. IT can be an essential strategy in the prescription of training for conditional improvement of variables of cardioprotective function in physically active and healthy older people. However, other studies are suggested to establish the efficiency of this method for cardiovascular and cardiorespiratory variables in the elderly.

“…In older adults, twice-weekly SIT (10 × 6 s sprints with 60 s recovery) has been shown to improve aerobic capacity (8% increase in predicted VO 2 max) and physical function (11% decrease in timed get up and go) after 6 weeks [15]. Following 10 weeks of the same SIT protocol, physical function was shown to be improved along with arterial stiffness and circulating lipids [16]. The lowest frequency reported for SIT is one session every 5 days (6 × 30 s sprints at 50% peak power with 3 min recovery) which resulted in a clinically relevant increase in peak power and greater lean body mass in older adults after 6 weeks [17].…”

Exercise is a powerful tool for improving health in older adults, but the minimum frequency required is not known. This study sought to determine the effect of training frequency of sprint interval training (SIT) on health and physical function in older adults. Thirty-four (13 males and 21 females) older adults (age 65 ± 4 years) were recruited. Participants were allocated to a control group (CON n = 12) or a once- (n = 11) or twice- (n = 11) weekly sprint interval training (SIT) groups. The control group maintained daily activities; the SIT groups performed 8 weeks of once- or twice-weekly training sessions consisting of 6 s sprints. Metabolic health (oral glucose tolerance test), aerobic capacity (walk test) and physical function (get up and go test, sit to stand test) were determined before and after training. Following training, there were significant improvements in blood glucose control, physical function and aerobic capacity in both training groups compared to control, with changes larger than the smallest worthwhile change. There was a small to moderate effect for blood glucose (d = 0.43–0.80) and physical function (d = 0.43–0.69) and a trivial effect for aerobic capacity (d = 0.01) between the two training frequencies. Once a week training SIT is sufficient to produce health benefits. Therefore, the minimum time and frequency of exercise required is much lower than currently recommended.
