Heart rate cost of running in track estimates velocity associated with maximal oxygen uptake.

Background: Running velocity associated with VOmax (vVOmax) is a parameter widely used for exercise prescription and is related to endurance performance. However, the vVOmax determination usually requires a maximal effort test and equipped laboratory for expired gas analysis, what make difficulty its assessment.

Objective: We aimed to test the validity of a simple method of vVOmax prediction through the heart rate cost of running (HRC) in a submaximal 6-min running test, both in treadmill and in a 400-meter track.

Functional capacity and obesity reflect the cognitive performance of older adults living in long-term care facilities.

Background: With the increase in life expectancy, the elderly Brazilian population has grown considerably. However, longevity is usually accompanied by problems such as the loss of functional capacity, cognitive decline, and deterioration in anthropometric parameters, particularly among those living in long-term care facilities. We analyzed the relationship among cognitive performance, anthropometry, and functional capacity in institutionalized elderly individuals.

Estimation of the Maximal Lactate Steady State Intensity by the Rating of Perceived Exertion.

The maximal lactate steady state is the gold standard for evaluating aerobic capacity; however, it is time-consuming. The lactate minimum protocol is an easier alternative, but is not feasible and still expensive. This study investigated whether the rating of perceived exertion of 13 is an accurate predictor of lactate minimum and maximal lactate steady state intensities.

Circulating miR-1, miR-133a, and miR-206 levels are increased after a half-marathon run.

Context: Circulating miRNAs are potential biomarkers that can be important molecules driving cell-to-cell communication.

Objective: To investigate circulating muscle-specific miRNAs in recreational athletes.

Materials And Methods: Three miRNAs from whole plasma before and after a half-marathon were analyzed by qPCR.

Reliability of vertical jump performance evaluated with contact mat in elderly women.

Unlabelled: The aim of this study was to evaluate the reliability of the vertical jump (VJ) using a contact mat in elderly women. Thirty-one physically active women aged 69·5 ± 5·6 years participated in this study. Jump performance was evaluated with a contact mat.

Relation of neck circumference and relative muscle strength and cardiovascular risk factors in sedentary women.

Objective: To verify the relation of neck circumference and relative muscle strength and cardiovascular risk factors in sedentary women.

Methods: A cross-sectional study with 60 premenopausal women (33.9±9.

Lactate threshold prediction by blood glucose and rating of perceived exertion in people with type 2 diabetes.

The validity of rating of perceived exertion (RPE) in predicting lactate threshold during an incremental test was analyzed in 15 men with type 2 diabetes (M age = 53.4 yr., SD = 12.
