Running Mechanics and Metabolic Responses With Water Bottles and Bottle Belt Holders.

Purpose: To determine whether differential kinematics, kinetics, rates of energy use, and cardiopulmonary responses occur during running with water bottles and bottle belt holders compared with running only.

Methods: Trained runners (N = 42; age 27.2 [6.

Comparison of the Vacuum Mattress versus the Spine Board Alone for Immobilization of the Cervical Spine Injured Patient: A Biomechanical Cadaveric Study.

Study Design: A biomechanical cadaveric study.

Objective: We sought to determine the amount of motion generated in an unstable cervical spine fracture with use of the vacuum mattress versus the spine board alone. Our hypothesis is that the vacuum mattress will better immobilize an unstable cervical fracture.

Biomechanical, metabolic and cardiopulmonary responses of masters recreational runners during running at different speeds.

This study tested interactions between age and running speed on biomechanics, metabolic responses and cardiopulmonary responses. Three-hundred participants ran at preferred and standardized speeds. Age group (younger, masters [≥40 years]) by speed (self-selected 8.

Exercise Benefits for Chronic Low Back Pain in Overweight and Obese Individuals.

Unlabelled: Overweight and obese individuals with chronic low back pain (LBP) struggle with the combined physical challenges of physical activity and pain interference during daily life; perceived disability increases, pain symptoms worsen, and performance of functional tasks and quality of life (QOL) decline. Consistent participation in exercise programs positively affects several factors including musculoskeletal pain, perceptions of disability due to pain, functional ability, QOL, and body composition. It is not yet clear, however, what differential effects occur among different easily accessible exercise modalities in the overweight-obese population with chronic LBP.

Shooting motion in high school, collegiate, and professional men's lacrosse players.

The purposes of this research were to quantify the kinematics of the lacrosse shot, based on arm dominance and player experience level. Male players (N = 39; 14-30 years; high school [n = 24], collegiate [n = 9], professional [n = 6]), performed overhead shots using dominant and non-dominant sides. Motion was captured using a high-speed, 12-camera optical system and high-speed filming.

Horizontal Slide Creates Less Cervical Motion When Centering an Injured Patient on a Spine Board.

Background: A patient with a suspected cervical spine injury may be at risk for secondary neurologic injury when initially placed and repositioned to the center of the spine board.

Objectives: We sought to determine which centering adjustment best limits cervical spine movement and minimizes the chance for secondary injury.

Methods: Using five lightly embalmed cadaveric specimens with a created global instability at C5-C6, motion sensors were anchored to the anterior surface of the vertebral bodies.

Review of Lacrosse-Related Musculoskeletal Injuries in High School and Collegiate Players.

Context: Participation in lacrosse has dramatically increased since 2001. Changes in the game rules, sport equipment, and athlete characteristics have all contributed to the injury patterns in lacrosse over time.

Objective: A summary of lacrosse-related musculoskeletal injuries.

Kinematic, Cardiopulmonary, and Metabolic Responses of Overweight Runners While Running at Self-Selected and Standardized Speeds.

Objective: To determine the differences in kinematic, cardiopulmonary, and metabolic responses between overweight and healthy weight runners at a self-selected and standard running speed.

Design: Comparative descriptive study.

Setting: Tertiary care institution, university-affiliated research laboratory.

Chronic pain management in the obese patient: a focused review of key challenges and potential exercise solutions.

In obese persons, general and specific musculoskeletal pain is common. Emerging evidence suggests that obesity modulates pain via several mechanisms such as mechanical loading, inflammation, and psychological status. Pain in obesity contributes to deterioration of physical ability, health-related quality of life, and functional dependence.
