Method ological factors affecting 6MWD include track length , encouragement , supplemental oxygen and walking aids .
Supplemental oxygen also affects ISWT and ESWT performance .
Responsiveness was moderate to high for all tests , with greater responsiveness to interventions that included exercise training .
The findings of this review demonstrate that the 6MWT , ISWT and ESWT are robust tests of functional exercise capacity in adults with chronic respiratory disease
This systematic review examined the measurement properties of the 6-min walk test ( 6MWT ) , incremental shuttle walk test ( ISWT ) and endurance shuttle walk test ( ESWT ) in adults with chronic respiratory disease .
OXYGEN RELIEVES BREATHLESSNESS IN "PINK PUFFERS"
The effect of oxygen on breathlessness and exercise tolerance was examined in " pink and puffing " patients with fixed airways obstruction . When breathing oxygen , patients were less breathless and walked further . This was true whether the cylinder was carried by the patient or by an assistant . It was not possible to identify those patients who would benefit most . The best method of assessing improvement was by comparing breathlessness on a st and ardised progressive exercise test on a treadmill .  Four patients had a greater than 30 % reduction in breathlessness on submaximum exercise when breathing oxygen . Breathing oxygen for five or fifteen minutes before exercise but not during exercise ( predose ) result ed in a similar improvement in exercise tolerance . For short periods of exercise predosing with oxygen provides a convenient alternative to continuous oxygen . For longer periods of exercise the benefits of portable oxygen in selected patients have been previously underestimated
