Telemedicine and home spirometry in cystic fibrosis: A prospective multicenter study.

Objectives: Telehealth and home spirometry feasibility for children has been established, but their impact on cystic fibrosis (CF) disease progression remains unassessed. We aimed to evaluate the effects of telehealth and home spirometry on CF disease progression and care.

Methods: Children with CF aged 5-17 years from all Swedish CF centers were provided with home spirometers.

Examination of the ZXY Arena Tracking System for Association Football Pitches.

Modern analyses of football games require precise recordings of positions and movements. The ZXY arena tracking system reports the position of players wearing a dedicated chip (transponder) at high time resolution. The main issue addressed here is the quality of the system's output data.

Effect of Computational Method on Accumulated O Deficit.

The aim of this study was to examine how relationships between exercise intensity and the rate of energy release established in different ways, affect the calculated O deficit accumulated during strenuous exercise. Aerobic energy release is readily measured by the O uptake, while anaerobic energy release is by definition independent of O. The latter is not easily measured during strenuous exercise, but it can be estimated using the accumulated O deficit principle.

Examination of a new functional firefighter fitness test.

Firefighters must meet certain physical requirements. This study compares the demands of a new firefighting-specific tasks test with an existing laboratory test. Thirty-five male subjects were tested.

The steady-state load of five firefighting tasks.

. Physiologic demands of five common tasks in firefighting have been examined. .
