“…The results showed an increase in HR during the practice of exergames, when compared to resting values, as observed in other studies [5,6,9,22]. The increase in HR is the result of autonomous and hemodynamic adaptations that influence the cardiovascular system [4,34,35].…”

Objective: To analyze the metabolic responses occurring during the practice of exergames in terms of energy expenditure, oxygen consumption rate, metabolic equivalent and heart rate in adult men and women. Methods: The present study sample was comprised of 102 adults (52 males). Energy expenditure, oxygen consumption rate and metabolic equivalent were assessed with a portable gas analyzer (K4b2). Heart rate was measured with a frequencymeter. All dependent variables were assessed at rest and during the exergame session, which was comprised of four X-box 360 games (volleyball, boxing, athletics, and bowling). Results: Mean age was 34.8 ± 13.4 years. There was a significant increase in resting values during exergame sessions for energy expenditure (male: 467.52%; p < 0.001; female: 393.72%; p < 0.001), oxygen consumption rate (male: 453.97%; p < 0.01; female: 384.74%; p < 0.001), metabolic equivalent (male: 457.40%; p < 0.001; female: 384.74%; p < 0.001) and heart rate (male: 95.10%; p < 0.001; female: 92.26; p < 0.001). When compared to women, men showed significantly higher values for energy expenditure (95% confidence interval = -12.53; -6.67), oxygen consumption rate (95% confidence interval = -4.01; -0.80) and metabolic equivalent (95% confidence interval = -1.18; 0.27) during exergames. Conclusion: A session of exergames is capable of increasing energy expenditure, oxygen consumption rate, metabolic equivalent and heart rate in adults. Men showed higher values in metabolic parameters when compared to women.

“…Disorders related to the cardiovascular and cardiorespiratory system are known to be the leading cause of disease and mortality worldwide [9,10] and appear to have more signi cant effects on the elderly [11]. Additionally, with the aging process, the cardiovascular functional decline is signi cant [12], where the maintenance and improvement of this system are essential for the organic integrity of the elderly [11].…”

Background Interval training is an important strategy for promoting physiological adaptations. Therefore, this study aimed to verify the chronic effects of interval training (TI) with different intensities on hemodynamic, autonomic and cardiorespiratory variables of physically active elderly people. Methods 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. Results 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. Conclusion 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.

“…Thus, assessing functional exercise capacity provides important information for the diagnosis and prognosis of cardiopulmonary function through the behavior of metabolic, cardiac and respiratory systems during the cardiopulmonary exercise testing (CPET) [9]. Despite CEPT is the gold standard to assess exercise tolerance, the cost is high, and it requires specialized and trained personnel.…”

Objetivo: O objetivo deste trabalho foi testar a hipótese que o teste de AVD-Glittre (TGlittre) tem validade concorrente e reprodutibilidade intra-avaliador em indivíduos com apneia obstrutiva do sono (AOS). Métodos: Foram avaliados 22 indivíduos, de ambos os sexos, com diagnóstico AOS. O TGlittre e o teste de esforço cardiopulmonar (TECP) foram realizados em dois dias diferentes, duas vezes cada, e a ordem era determinada por randomização. Resultados: A FC máxima (FCmáx) obtida no TGlittre foi de 130,6 ± 13,3 bpm e o tempo total para a realização do teste foi de 3,4 ± 0,5 min. Sobre as varáveis analisadas no TECP, foram obtidos os seguintes valores: consumo máximo de oxigênio (VO2máx) = 2,4 ± 5,3 ml/kg/min, VO2 no primeiro limiar = 19,4 ± 3,9 ml/kg/min, FCmáx = 161,3 ± 15,2 bpm e o tempo total de realização do teste foi de 8,3 ± 1,6 min. Uma correlação negativa moderada foi verificada entre o tempo de realização do TGlittre e VO2max (r = -0,424; p = 0,049). Na análise da confiabilidade teste-reteste do tempo total de realização do TGlittre, foi observada uma excelente concordância e consistência entre as medidas (coeficiente de correlação intraclasse (CCI) = 0,865; IC95%: 0,379-0,965 (p ≤ 0,0001). Conclusão: O teste de TGlittre é válido e reprodutível na AOS. Além disso, é um teste de intensidade submáxima, fácil aplicação e baixo custo, que pode ser utilizado em larga escala.
