Long-Term Outcome After Decompressive Craniectomy in a Developing Country.

Background: Decompressive craniectomy (DC) may reduce mortality but might increase the number of survivors in a vegetative state. In this study, we assessed the long-term functional outcome of patients undergoing DC in a middle-income country.

Methods: This was a prospective observational study of patients undergoing DC at a single tertiary hospital in southern Brazil between January 2015 and December 2018.

Effects of a Real-Life Park-Based Physical Activity Interventional Program on Cardiovascular Risk and Physical Fitness.

Introduction: Regular physical activity (PA) practice is a way to combat cardiovascular disease, and a PA interventional program, including individualized prescription of walking with limited supervision of execution, may be a strategy to be applied in public parks. Thus, our study tested the effects of a real-world program like this on cardiovascular risk and cardiorespiratory fitness (CF) of the users of a public park.

Methods: Data came from the Exercise and Heart Project, a real-life park-based PA interventional program.

Development and Validation of a Checklist to Assess Proficient Performance of Basketball Straight Speed Dribbling Skill.

The aim of this study was to develop and validate a checklist to assess proficient performance of basketball straight speed dribbling skill. The sample was composed of 100 children and adolescents between 7 and 15 years of age with and without structured practice in basketball. The validation process tested the validity domain, decision, tendencies, reliability, responsiveness, and objectivity.

Familial aggregation and heritability of markers of metabolic risk, physical activity, and physical fitness in nuclear families from Muzambinho (Minas Gerais, Brazil).

Objective: This study investigated the familial aggregation and heritability of markers of metabolic risk, physical activity, and physical fitness in nuclear families from Muzambinho (Minas Gerais, Brazil).

Subjects And Methods: The study included members of 139 families, comprising 97 fathers (aged 40 ± 7 years), 129 mothers (35 ± 6 years), 136 sons (12 ± 4 years), and 121 daughters (12 ± 5 years). Evaluated markers included (A) body mass index, waist circumference, glycemia, and cholesterolemia, as metabolic risk markers; (B) total weekly volume of physical activity, as a physical activity marker; and (C) relative muscle strength, as a physical fitness marker.

No Improvement on the Learning of Golf Putting By Older Persons With Self-Controlled Knowledge of Performance.

The aim of this study was to verify if older adults would benefit from a self-controlled schedule of knowledge of performance (KP) in the motor skill learning. The study's participants included 22 women and 18 men, with an average age of 68 years ( = 2.95 years).

Acute Spontaneous Subdural Hematoma in Posterior Fossa: Great Outcome.

Background: Acute subdural hematomas are frequently seen in brain trauma-injured patients. However, spontaneous subdural hematomas are uncommon, especially those localized in the posterior fossa, where fewer than 10 case reports have been described in the medical literature.

Case Description: We describe a patient who suddenly had a headache and progressed rapidly to coma and signs of brainstem compression.

Relationship between physical activity, physical fitness and multiple metabolic risk in youths from Muzambinho's study.

Negative associations between physical activity (PA), physical fitness and multiple metabolic risk factors (MMRF) in youths from populations with low PA are reported. The persistence of this association in moderately-to highly active populations is not, however, well established. The aim of the present study was to investigate this association in a Brazilian city with high frequency of active youths.

Frequency of provision of knowledge of performance on skill acquisition in older persons.

The provision of feedback is a crucial factor for the evolution of the learner's performance. It is known that the knowledge of performance has the function of guiding the learner's attention to critical aspects of the movement pattern. The objective of this study was to examine the effect of frequency of knowledge of performance (KP) during the acquisition of the basketball free throw in older persons.

An adaptive process model of motor learning: insights for the teaching of motor skills.

This article presents an outline of a non-equilibrium model, in which motor learning is explained as a continuous process of stabilization and adaptation. The article also shows how propositions derived from this model have been tested, and discusses possible practical implications of some supporting evidence to the teaching of motor skills. The stabilization refers to a process of functional stabilization that is achieved through negative feedback mechanisms.

Relative frequency of knowledge of results and task complexity in the motor skill acquisition.

The aim of this study was to investigate the effects of knowledge of results (KR) frequency and task complexity on motor skill acquisition. The task consisted of throwing a bocha ball to place it as close as possible to the target ball. 120 students ages 11 to 13 years were assigned to one of eight experimental groups according to knowledge of results frequency (25, 50, 75, and 100%) and task complexity (simple and complex).

Modularity and hierarchical organization of action programs in human acquisition of graphic skills.

If motor or action programs become modules with practice their defining features (e.g. relative timing) should remain relatively invariant in new tasks.
