Determinants of recovery from a 161-km ultramarathon.

The primary study objective was to identify determinants of short-term recovery from a 161-km ultramarathon. Participants completed 400 m runs at maximum speed before the race and on days 3 and 5 post-race, provided a post-race blood sample for plasma creatine kinase (CK) concentration, and provided lower body muscle pain and soreness ratings (soreness, 10-point scale) and overall muscular fatigue scores (fatigue, 100-point scale) pre-race and for 7 days post-race. Among 72 race finishers, soreness and fatigue had statistically returned to pre-race levels by 5 days post-race; and 400 m times at days 3 and 5 remained 26% (P = 0.

A Randomized Controlled Trial of Massage and Pneumatic Compression for Ultramarathon Recovery.

Study Design Randomized controlled trial. Background Postexercise recovery techniques are widely used, but little research has examined their effectiveness. Objectives To examine the effectiveness of massage and pneumatic compression on recovery from a 161-km ultramarathon.

Incidence and Prevalence of Acute Kidney Injury During Multistage Ultramarathons.

Objective: Determine prevalence, incidence, and risk factors of acute kidney injury (AKI) during multistage ultramarathons.

Setting: Jordanian Desert 2012; Atacama Desert, Chile 2012 and 2013; and Gobi Desert 2013 RacingThePlanet 250 km, 6-stage, ultramarathons.

Optimizing lavage during knee arthroscopy: a three-dimensional MRI study.

Purpose: To determine the best positioning and the resulting fluid flow patterns inside the knee during arthroscopy, reducing the surgical morbidity associated with the arthroscopic irrigation and debridement of a septic knee joint.

Materials And Methods: Three-dimensional MRI, using an MRI-compatible human cadaveric knee arthroscopic model, generated fluid flow diagrams and velocity vector data. This was analyzed for six different arthroscopic configurations and at six different locations within the knee joint.

Understanding household behavioral risk factors for diarrheal disease in Dar es Salaam: a photovoice community assessment.

Whereas Tanzania has seen considerable improvements in water and sanitation infrastructure over the past 20 years, the country still faces high rates of childhood morbidity from diarrheal diseases. This study utilized a qualitative, cross-sectional, modified Photovoice method to capture daily activities of Dar es Salaam mothers. A total of 127 photographs from 13 households were examined, and 13 interviews were conducted with household mothers.
