Measurement of various intensities of physical activities and categorization of "Locomotive" and "Household" activities provide a subject-specific detailed assessment.

This study aimed to compare the physical activity (PA) measured by a wearable sensor device (WSD) and the step count measurement, and to investigate the association between PAs and lifestyle. Data of 301 participants were collected from March 2019 to March 2021. Step counts, sedentary behavior, performance time of light/moderate/vigorous PA, METs × hour of "Locomotive" and "Household" categorized activities, and energy expenditure (EE) were measured by the WSD, respectively.

The relationship between clinically measured hip rotational motion and shoulder biomechanics during the pitching motion.

Objectives: To examine how clinically measured hip motion is related to shoulder biomechanics during the pitching motion.

Design: Cross-sectional.

Methods: Bilateral hip rotational range of motion was measured clinically among 34 collegiate baseball pitchers.

Thoracolumbar range of motion in baseball pitchers and position players.

Introduction/background: Optimal baseball throwing mechanics require a significant contribution of thoracolumbar motion, particularly in the sagittal and transverse planes. This motion is key for proper transmission of forces from the lower to upper extremity, thereby minimizing a throwing athlete's risk of injury and maximizing athletic performance.

Purpose: To define the active-assisted thoracolumbar ROM of both baseball pitchers and position players and to compare these motions both within and between groups.
