This study investigated the initial three-month impact of the COVID-19 pandemic on the explicit processes towards physical activity (PA). In addition, we explored whether potential changes in explicit processes are associated with changes in PA and sedentary behavior (SB). Seventeen older adults (aged 65.7 ± 3.8 years; 76.5% women) with hypertension were included in this longitudinal study performed in Natal, Brazil. Explicit processes (explicit attitude [perceived benefits and cons perceived], social norms, social modeling, self-efficacy, intention and motivation) were evaluated through self-reported questionnaire before (January to March 2020) and during (June 2020) the COVID-19 pandemic. In addition, PA and SB were measured by accelerometry during seven days. Generalized linear and mixed models were used for data analysis. There was a decrease in the explicit attitudes (β = – 4.8, p = 0.001) and moderate-vigorous PA (β = – 4.8, p = 0.035) during the COVID-19. Changes in the explicit attitudes were associated with the changes in the moderate-vigorous PA (β = – 1.6, 95% CI – 2.9, – 0.3, p = 0.034). No significant changes were found in the additional explicit process measures, time spent doing light PA and SB, and step count. Our findings may suggest that the COVID-19 pandemic has negatively impacted the explicit attitudes related to PA and contributed to decrease the time spent in the moderate-vigorous PA in older adults with hypertension.

Objectives: Herein, we explored the associations of pre-pandemic COVID-19 physical activity (PA), sedentary behavior (SB) and cardiorespiratory fitness (CRF) with mental health and quality of life in older adults with hypertension. Method: Objectively measured PA and SB, perceived stress, depression symptoms, and quality of life were assessed before and during the pandemic in seventeen older adults with hypertension. CRF was assessed before the pandemic by cardiopulmonary exercise testing. Longitudinal and cross-sectional associations were analyzed using the mixed linear model. Results: Pre-pandemic light PA (positive association) and SB (negative association) were associated with quality of life during the pandemic. Higher pre-pandemic CRF was associated with less negative changes in perceived stress, depression symptoms, and quality of life during the pandemic. Conclusion: Our preliminary findings suggest that a healthier pre-pandemic movement behavior (more PA, less SB) and better CRF can mitigate the negative impact of the COVID-19 pandemic on mental health and quality of life in older adults with hypertension.

This article compare Vertical Jump (VJ) and Handgrip Strength (HS) in basketball athletes by playing position and performance. The sample was composed of 183 male athletes. To evaluate the strength of the upper limbs, the HS isometric force test was used, while for the lower limbs the VJ countermovement test. In addition, it was analyzed maximum reach (MR), as well as was analyzed relative strength. It was observed that the centers displayed the lowest VJ score (p = .029). Regarding MR, centers displayed the highest score (p < .001). Regarding dominant HS, the guards displayed the lowest scores (p = .005) as well as non dominant HS (p = .023). It was found that G4 presented higher VJ (p < .001), as well as MR (p < .001). No difference was found regarding dominant and non dominant absolute HS, as well as relative scores (p > .05). It was found higher VJ performance in G4 athletes in every playing position (Guards: p = .042, Forwards: p = .005 and Centers: p = .032) as well as in MR (Guards: p = .002, Forwards: p = .002 and Centers: p = .002). No difference was found regarding dominant and non dominant HS and relative HS of dominant and non dominant hand between G4 and Z4 in any playing position (p > .05). In this sense, it is possible to conclude that different playing positions demand specific physical profile and motor skills, probably due to the difference in technical and tactical requirements that are assigned to each playing position.

Background: This study reports the accelerometer-based physical activity (PA) and sedentary behavior (SB) before and during the COVID-19 pandemic in hypertensive older adults., Methods: Thirty-five hypertensive older adults were included in this observational study. Accelerometer-based PA and SB measures were assessed before (January to March 2020) and during (June 2020) the COVID-19 pandemic. Linear mixed models were used to assess within-group changes in PA and SB measures, adjusted by accelerometer wear time., Results: Before COVID-19 pandemic participants presented: 5809 steps/day (SE = 366), 303.1 min/day (SE = 11.9) of light PA, 15.5 min/day (SE = 2.2) of moderate-vigorous PA, and 653.0 min/day (SE = 12.6) of SB. During COVID-19 pandemic there was a decrease in steps/day (β = -886 steps/day, SE = 361, p = 0.018), in moderate-vigorous PA (β = -2.8 min/day, SE = 2.4, p = 0.018), and a trend in light PA (β = -26.6 min/day, SE = 13.4, p = 0.053). In addition, SB increased during the COVID-19 pandemic (β = 29.6 min/day, SE = 13.4, p = 0.032). The magnitude of changes was greater on the weekend, mainly for steps/day (β = -1739 steps/day, SE = 424, p < 0.001) and the SB pattern (more time spent in bouts of ≥10 and 30 min, less breaks/day and breaks/h)., Conclusions: The COVID-19 pandemic may elicit unhealthy changes in movement behavior in hypertensive older adults. Lower PA, higher and more prolonged SB on the weekend are the main features of the behavioral changes., (Copyright © 2020 Elsevier Inc. All rights reserved.)
