Background: The responsiveness of the endurance shuttle walk to functional changes following bronchodilation has recently been reported. The current literature suggests that the 6 min walking test (6MWT) is less responsive to bronchodilation than the endurance shuttle walk. Aim: To compare bronchodilator-induced changes in exercise performance with the 6MWT and the endurance shuttle walk. Metho...

The purpose of the present study was to examine the validity of using a 20 m progressive shuttle run test to estimate maximal oxygen uptake. Running ability was described as the final level attained on the shuttle run test and as time on a 5 km run. Maximal oxygen uptake (VO2 max) was determined directly for seventy-four volunteers (36 men, 38 women) who also completed the shuttle run test. Max...

Ceramic industrial kiln refers to the combustion equipment for ceramic production, which generally roller kiln, shuttle tunnel and kiln. Roller with continuous firing rotating as vehicle of billet body; Tunnel adopts takes rail car transport body. Shuttle is fired intermittently consists car, chamber door. Factors influencing energy saving include construction materials, structure, technology, ...

We consider the discrete time problem of optimally dispatching a single, nite capacity shuttle in a two terminal system under incomplete state observations. Passengers arrive to each terminal and must be moved to the other terminal. The durations of successive shuttle trips follow a general distribution, but have a lower bound D 1 . There is an information delay of I time units between the two ...

BACKGROUND The aim was to develop a standardised and externally paced field walking test, incorporating an incremental and progressive structure, to assess functional capacity in patients with chronic airways obstruction. METHODS The usefulness of two different shuttle walking test protocols was examined in two separate groups of patients. The initial 10 level protocol (group A, n = 10) and a...

This study examined whether 20-m shuttle-run performance, sex, body mass index (BMI), age, height, and weight are associated with peak oxygen uptake (VO2peak) in youth with Down syndrome (DS; n = 53; 25 women, age 8-20 years) and whether these variables can be used to develop an equation to predict VO2peak. BMI, 20-m shuttle-run performance, and sex were significantly associated with VO2peak in...

Objective: To determine whether the triple-crossover hop and timed shuttle run are able to discriminate between injured and uninjured limbs in subjects with functional ankle instability. Design and Setting: A comparative study involving the assessment of functional performance, conducted in a university gymnasium. Participants: A volunteer sample of 16 university-age subjects with unilateral fu...
