Item type: Item , Leveraging the global growth of running to promote physical activity at the populational level(2025) Santos, Mabliny Thuany Gonzaga; Petreça, Daniel Rogério; Lira, Claudio Andre Barbosa deItem type: Item , Determinants of mortality risk in older adults from the ELSIA study: a prospective cohort study(2025) Galvão, Lucas Lima; Santos, Douglas de Assis Teles; Lira, Claudio Andre Barbosa de; Virtuoso Júnior, Jair Sindra; Tribess, Sheilla; Viana, Ricardo Borges; Reis, Anne Sulivan Lopes da Silva; Weiss, Katja; Knechtle, Beat; Vancini, Rodrigo LuizBACKGROUND: This study investigated factors that may determine longevity in older adults, aiming to prolong their life expectancy and improve projections from before the coronavirus disease 2019 pandemic. OBJECTIVE: To identify risk factors for mortality in older Brazilian adults. DESIGN AND SETTING: A prospective cohort study, part of the Estudo Longitudinal de Saúde do Idoso de Alcobaça. METHODS: This study included 332 older adults of both sexes who were followed up for over five years (2015–2020). Vital status was determined via telephone follow-up, information provided by family members, and death certificates. To identify the sociodemographic, health, functional, and behavioral factors associated with mortality risk among older adults, Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: The risk factors for mortality among older adults included the number of people living with them (HR = 1.22; 95%CI = 1.07–1.38) and the number of prescribed drugs (HR = 1.15; 95%CI = 1.00–1.32). Factors associated with a lower risk of mortality were greater time spent in physical activity (HR = 0.99; 95%CI = 0.90–0.99) and greater hip circumference (HR = 0.95; 95%CI = 0.31–0.99). CONCLUSIONS: Sociodemographic, health, functional, and behavioral factors are determinants of mortality risk among older adults. Regular screening of the older adult population should be conducted to assess their general health status, allowing for more appropriate interventions to increase their quality of life and improve agingItem type: Item , One-minute stages are optimal for maximal exercise testing in endurance male and female athletes(2025) Campos, Alice de; Lira, Claudio Andre Barbosa de; Vancini, Rodrigo Luiz; Freitas, João Victor Rosa de; Weiss, Katja; Rosemann, Thomas Johannes; Knechtle, Beat; Andrade, Marilia dos SantosObjective: Over the last 40 yr., there has been a relative consensus that incremental exercise tests used to determine Maximal Oxygen uptake (V˙O2max), maximal aerobic intensity, and ventilatory thresholds should last between 8 and 12 min. However, recent studies have questioned this recommendation, suggesting that it may be outdated, although this is not yet established in the literature. This study compared V˙O2max, Maximum Aerobic Power (MAP), and ventilatory thresholds between two incremental exercise protocols in amateur endurance athletes. Methods: Thirteen women and 15 men (aged 24–53 yr) completed two maximal progressive tests, performed in random order (short-term and long-term), with a 2- to 4-day interval. In the short-term test, the workload increased by 25 W per minute, while in the long-term test, the workload increased by 25 W every 3 min. Both protocols were performed until exhaustion. The variables assessed included ventilatory threshold (VT), Respiratory Compensation Point (RCP), V˙O2max, MAP, Maximal Heart Rate (HRmax), and maximal oxygen pulse. Results: No significant differences were found between the short-term (8–12 min) and long-term (19–28 min) protocols for V˙O2max (p = 0.79), HRmax (p = 0.715), or maximal oxygen pulse (p = 0.40). However, absolute and relative MAP (p < 0.001) and power at RCP (p < 0.001) were significantly lower in the short-term protocol. Moreover, men showed a greater reduction in MAP during long-term tests than women. Conclusions: These findings suggest that 1-min stage tests are more time-efficient and effective for assessing V˙O2max and MAP.Item type: Item , Effect of swimming intensity on performance in subsequent sprint triathlon: a sex-based analysis in amateur athletes(2025) Martins, Lavínia Vivan Ferreira; Souza, Vinícius Ribeiro dos Anjos; Engelke, Paulo Medeiros; Lira, Claudio Andre Barbosa de; Vancini, Rodrigo Luiz; Weiss, Katja; Knechtle, Beat; Andrade, Marilia dos SantosPurpose Generally, triathletes participating in short events should aim to finish the swim stage with the leading group to improve their chances in the subsequent cycling and running stages. However, the fatigue associated with very intense swimming can impair subsequent split times. This study aimed to investigate the impact of swimming bout intensity on performance in subsequent cycling, running, and overall racing among well-trained male and female amateur triathletes. Methods Twenty athletes (12 men and 8 women) participated in this study. Critical velocity (CV) was estimated for swimming using a simple linear model. Body composition and maximal oxygen uptake were measured. Participants visited the laboratory three times to swim 750 m at intensities below CV, at CV, and above CV (in randomized order), before they cycled 20 km and ran 5 km as fast as they could to simulate a sprint triathlon. Heart rate, blood lactate level, perceived exertion, muscle pain, and dyspnea levels were measured at the end of each modality. Results For women, on the day on which swimming intensity was below the CV, the overall race time was higher than on the day on which swimming intensity was at the CV (p = 0.041) or faster than the CV (p = 0.002). For men, there was no significant difference in the overall race time among the three intensities (p > 0.05). Conclusion The results showed that, for men, swimming at higher intensity did not significantly change total time, whereas for women, lower intensity was associated with poorer performance.Item type: Item , Regular physical activity and its components as predictors of depressive symptoms in young Brazilians after mandatory military service: a prospective cohort study(2025) Morais, Naiane Silva; Silva, Rizia Rocha; Rodrigues, Mila Alves Matos; Santos, Lucas dos; Menezes, Vanessa Assis; Malysz, Taís; Braz, Allison Gustavo; Vancini, Rodrigo Luiz; Andrade, Marília dos Santos; Weiss, Katja; Rosemann, Thomas Johannes; Knechtle, Beat; Lira, Claudio Andre Barbosa deBackground: The prevalence of depressive symptoms among recruits in mandatory military service is a growing concern owing to its potential impact on the physical and psychological functions essential for military activities. Regular physical activity, especially in militarized environments, may contribute to mental health. Nonetheless, the association between the two needs to be investigated further. Objective: This study examined the link between habitual physical activity and depressive symptoms in recruits. Furthermore, it assessed whether high levels of physical activity were a protective factor against depressive symptoms at the end of mandatory military service. Materials and methods: This longitudinal study included 156 Brazilian Army recruits who completed a period of mandatory military service. The Beck Depression Inventory was used to evaluate depressive symptoms, and the Baecke Physical Activity Questionnaire was used to measure habitual physical activity (HPA) levels. Poisson regression models were employed to determine the association between depressive symptoms and physical activity components. Results: High scores in total HPA, especially in the sports domain, were significant protective factors against depressive symptoms (p < 0.05). Poisson regression showed a reduced relative risk (RR) of depressive symptoms in case of high HPA levels: RR of 0.65 for total HPA and 0.46 for the sports domain. Optimal cutoff points for predicting depressive symptoms were ≤ 2.5 for sports and ≤ 8.75 for total HPA. This finding suggests that increased physical activity, especially in sports, may alleviate depressive symptoms in this population. Conclusions: Promoting structured physical activity, especially sports, may be an effective strategy to reduce depressive symptoms among young adults after mandatory military service. However, further research is required to explore the underlying mechanisms and develop optimized interventions for this population.
