摘要

Introduction and Objective Endurance training during PR requires exercise prescription at sufficient intensity to achieve physiological benefits. This analysis sought to investigate whether walking training prescribed from 6-minute walk test (6MWT) average speed provides an appropriate training intensity for people with ILD during PR. Methods Individuals with ILD completed cardiopulmonary exercise test (CPET) and 6MWT in random order. A 10-minute constant speed treadmill walk test (10MTW) was undertaken at 80% of the average 6MWT speed. Oxygen uptake (VO2) was measured during all tests. Percentage VO(2)peak during 10MTW was main outcome measure. Results Eleven people with ILD (age 71 (8) years; forced vital capacity 73 (18) %predicted, 6-minute walk distance 481 (99) meters, and VO(2)peak during CPET 1.3 (0.2) L.min(-1)) undertook testing. Average VO(2)peak during 10MTW was 91 (18) % of CPET VO(2)peak [range 67-116%]. Participants who achieved a greater VO(2)peak during CPET walked at a smaller %VO(2)peak during 10MTW (r = -0.6; p = .04). Conclusions For people with ILD, walking training prescribed at 80% of 6MWT average speed can provide adequate exercise training intensity for PR.
