Opis:
Background: The inclusion of gymnastic-based movements in workout routines in many exercise training programs, generally called mixed modality training (MMT), and even in many competitions, is increasingly common. In contrast to artistic gymnastic competitions, MMT workouts aim to complete as many movements as quickly as possible, which tends to deform the movement pattern proposed by artistic gymnastics. Execution of the MMT workouts with more of the gymnastics-based style (i.e., based on the gymnastics movement pattern) could improve performance in exercises with a high-level complexity, such as the “ring muscle up” (RMU). Thus, this study aimed to analyze the kinematic aspects of RMU, performed by a former gymnast both with and without the gymnastics based style. Methods: A former gymnast with a successful transition to MMT, carried out RMU using two movement patterns: 1) close to the classical artistic gymnastics pattern (“Front uprise”), and 2) close to that used by many athletes not from gymnastics. The athlete performed RMU, three times with each proposed movement pattern. Images were captured using a high-speed digital camera. Hip and ankle displacement, velocity and acceleration were recorded and analyzed. Results: The execution of RMU was faster and the hip vertical displacement was greater when RMU was carried out with a gymnastics-based style, while ankle displacement path, peak velocity and acceleration were lower. Conclusion: The use of a gymnastics-based style to carry out RMU seems to be advantageous from the biomechanical point of view, favoring the performance of RMU.

Opis:
We study the algebraic structure of orthogonal models thus of mixed models whose variance covariance matrices are all positive semi definite, linear combinations of known pairwise orthogonal projection matrices, POOPM, and whose least square estimators, LSE, of estimable vectors are best linear unbiased estimator, BLUE, whatever the variance components, so they are uniformly BLUE, UBLUE. From the results of the algebraic structure we will get explicit expression for the LSE of these models.

Opis:
This study aimed to compare measures of religiosity and spirituality in the experience of positive and negative emotions. For this purpose, a measure of non-spiritual religiosity (Religious Sense Scale) was developed. Method: The study has been conducted on a sample of 279 participants aged between 19 and 69 (M=24.42, SD=9.463) who completed a questionnaire that included the Religious Sense Scale, the Portuguese version of the Spiritual Well-being Questionnaire and the abridged Portuguese version of the Positive and Negative Affect Schedule. Findings: The was found to have excellent metrical properties for the measurement of religiosity or “religious sense”. Religious individuals differ from spiritual ones in the experience of emotions: spirituality tends to a greater experience of positive affect and religiosity to negative affect.

Opis:
ObjectivesTo assess the seroprevalence of SARS-CoV-2 antibodies in municipal employees of Northern Portugal during the first pandemic wave (May–June 2020) and its association with potentially related risk factors for infection.Material and MethodsThe authors assessed municipal employees of 2 cities in Northern Portugal, in whom serological tests to SARS-CoV-2 and an epidemiological survey were applied. The authors assessed the proportion of individuals presenting IgM and/or IgG antibodies to SARS-CoV-2, and evaluated the association between having positive serological test results, epidemiologic variables and clinical presentations. Reported symptoms were evaluated on their sensitivity, specificity, and predictive values.ResultsThe authors assessed 1696 employees, of whom 22.0% were firefighters, 10.4% were police officers, 10.3% were maintenance workers, and 8.1% were administrative assistants. The seroprevalence of SARS-CoV-2 infection was 2.9% (95% CI: 2.1–3.7%). Administrative assistants comprised the professional group with highest seroprevalence of SARS-CoV-2 (OR = 1.9 in the comparison with other occupational groups, 95% CI: 0.8–4.3, p = 0.126). The seroprevalence of SARS-CoV-2 infection among those who were in direct contact with COVID-19 patients in their professional activity was 3.9%, compared to 2.7% among those who were not in direct contact with such patients (OR = 1.5, 95% CI: 0.8–2.8, p = 0.222). The highest risk of infection was associated with the presence of a confirmed SARS-CoV-2 infection in the household (OR = 17.4, 95% CI: 8.3–36.8, p < 0.001). Living with a healthcare professional was not associated with a higher risk of infection (OR = 1.0, 95% CI: 0.4–2.5, p = 0.934). Anosmia/dysgeusia was the symptom with the highest positive predictive value (52.2%, 95% CI: 31.8–72.6, p < 0.001) and specificity (99.3%, 95% CI: 98.9–99.7, p < 0.001), while cough was the most prevalent symptom among SARS-CoV-2 seropositive participants (36%).ConclusionsThe authors observed a SARS-CoV-2 seroprevalence of 2.9% among assessed municipal employees. Anosmia/dysgeusia was the COVID-19 symptom which displayed the highest positive predictive value and specificity.
