Standing Handball Throwing Velocity Estimation with a Single Wrist-Mounted Inertial Sensor

Background. It is well known that overarm throwing is one of the most performed activities in the handball. Shoulder and glenohumeral injuries incidence are high in handball because of both pass, and shooting activity was executed repeatedly in high angular speed. Objectives. This study set out to investigate the usefulness of inexpensive commercial inertial movement sensors for prediction of ...

ROENTGENOGRAM OF THE MONTH 77 © 1 ? i D # { 174 } Rapidly Progressing Diffuse Pulmonary Infiltrate

A 30-year-old man, a nonsmoker, was admitted to the hospital with symptoms of alcoholic withdrawal. A roentgenogram of the chest was obtained on admission (Fig 1). The physical examination was unremarkable except for neurologic changes. A few days later, he developed fever, became hypoxemic and dyspneic, and worsened clinically. A second chest roentgenogram was obtained 12 days after admission ...

Designing and Determining the Validity and Reliability of a Dart Throwing Observation Form: A 10th Grade Dart Module for Physical Education

Standard academic progress tests in physical education play an important role when it comes to assessing students’ progress, pinpointing their strengths and weaknesses and categorizing them. The present research has aimed to design and examine the reliability and validity of an observation form for the process of throwing darts. The testees participating in the research were darts players (male...

Enhanced Expectancies Improve Performance Under Pressure

Beyond skill, beliefs in requisite abilities and expectations can affect performance. This experiment examined effects of induced perceptions of ability to perform well under generic situations of challenge. Participants (N = 31) first completed one block of 20 trials on a throwing accuracy task. They then completed questionnaires ostensibly measuring individual differences in the ability to pe...
