Two new species and an updated key: Melastomateae from the Serra da Canastra National Park, Minas Gerais, Brazil.

Here we describe and illustrate and two new species of the Melastomateae tribe from Serra da Canastra National Park, Minas Gerais, Brazil. We also provide an updated identification key for the members of the tribe that occur in this Protected Area. has coriaceous leaves, broadly ovate to orbicular leaf blade, entire and adpressed-strigose margin, 11-17 basal acrodromous veins, and flowers with white petals.

Dose-response relationship between very vigorous physical activity and cardiovascular health assessed by heart rate variability in adults: Cross-sectional results from the EPIMOV study.

The minimum amount of physical activity needed to obtain health benefits has been widely determined. Unlikely, the impact of extreme amounts of very vigorous physical activity (VVPA, ≥ 8 metabolic equivalents) to the heart remains controversial. We aimed to evaluate the dose-response relationship between VVPA and heart rate variability (HRV) in adults.

Screening for physical inactivity among adults: the value of distance walked in the six-minute walk test. A cross-sectional diagnostic study.

Context And Objectives: Accelerometry provides objective measurement of physical activity levels, but is unfeasible in clinical practice. Thus, we aimed to identify physical fitness tests capable of predicting physical inactivity among adults.

Design And Setting: Diagnostic test study developed at a university laboratory and a diagnostic clinic.
