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 .
6-minute walk distance in healthy North Africans older than 40 years: influence of parity.
The need for a 6-min walk distance ( 6-MWD ) reference equation for healthy North African adults older than 40 years was assessed in a prospect i ve cross-sectional study .  Anthropometric data and 6-MWD  were measured in 229 healthy Tunisian adults ( 125 women ) over 40 years old . Two subgroups of 38 women were identified according to the parity ( low < or=5 ; high > or=6 ) . The published reference equations did not reliably predict measured 6-MWD . The 6-MWD was significantly correlated with gender , age , weight and height ( p<0.001 ) . The combination of these parameters explained 77 % of the 6-MWD variability in the equation : 6-MWD (m)=-160.27 x gender ( 0 : men ; 1 : women ) - 5.14 x age ( yr ) - 2.23 x weight (kg)+2.72 x height (cm)+720.50 . Parity accelerated the 6-MWD decline ( r=-0.39 , p<0.05 ) and women distinguished only by parity ( < or=5 vs. > or=6 ) showed different 6-MWD ( 589+/-60 m vs. 555+/-57 m , p<0.05 ) . In an additional group of 30 adults prospect ively studied to vali date the equation , the agreement between the measured and equation-predicted 6-MWD was satisfactory . In conclusion , this reliable 6-MWD reference equation enriches the World Bank and provides an important element of interpretation for women with high parity
