However, the physiological demands and magnitude of desaturation on 6-min walk test (6MWT), incremental shuttle walk test (ISWT), and endurance shuttle walk test (ESWT) have not been investigated in patients with bronchiectasis. The objective of this study was to compare the physiological responses and the magnitude of desaturation of subjects with bronchiectasis when performing the 6MWT, ISWT, and ESWT.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>\n                      Thirty-two subjects underwent the 6MWT, ISWT, and ESWT on 3 different days.

Equivalent cardiac demand (ie, heart rate at peak) was observed with the 6MWT (137 \u00b1 21 beats\/min) and the ESWT (142 \u00b1 21 beats\/min), but this was lower in the ISWT (135 \u00b1 19 beats\/min) compared to ESWT (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .05). Most subjects achieved a vigorous exercise intensity (heart rate of 70\u201390% of predicted) in all tests. There was no difference in desaturation among the tests (6MWT: \u22126.8 \u00b1 6.6%, ISWT: \u22126.1 \u00b1 6.0%, and ESWT: \u22127.0 \u00b1 5.4%).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>The 6MWT, ISWT, and ESWT induced similar physiological responses at the peak of exercise, eliciting a vigorous exercise intensity. The magnitude of desaturation was similar across tests.
