Trial Outcomes & Findings for Effects of a Walking Program and Inspiratory Muscle Training in Individuals With Chronic Heart Failure (NCT NCT01560871)
NCT ID: NCT01560871
Last Updated: 2020-04-03
Results Overview
This questionnaire includes 21 questions which ask how much the heart condition affected the patient's life during the past month. Each question has 5 optional answers with the scores ranging from 0 to 5. A higher score indicates a worse outcome. The minimum overall score of the questionnaire is 0 and the maximum score is 105. A higher overall score on the Minnesota Living with Heart Failure Questionnaire indicates a worse outcome.

Low-intensity IMT Plus Walking
Inspiratory Muscle Training (IMT) intensity is set at 15% PImax. The walking program consists of walking daily at an intensity of "somewhat hard" to "hard" on the Rating of Perceived Exertion scale. Participants are encouraged to walk 15 minutes twice a day, then progress to 45-50 minutes a day by six weeks.
Low-intensity IMT plus walking: The IMT training is about 15-20 minutes. Both groups will need to come in once a week for 15 to 20 minutes to probably readjust the IMT training intensity on the breathing device.
For the walking program, each participant will be given a pedometer and a heart rate monitor so he/she can track daily step counts and walking heart rate during the study. The walking program will consist of walking every day at an intensity of "hard" to "somewhat hard" on the Rating of Perceived Exertion (RPE) scale. Participants will begin walking at least 15 minutes twice a day for 7 days a week and eventually pr

High-intensity IMT Plus Walking
Inspiratory Muscle Training (IMT) intensity is set at 60% PImax. The walking program will consist of walking daily at an intensity of "somewhat hard" to "hard" on the Rating of Perceived Exertion scale. Participants are encouraged to walk 15 minutes twice a day initially, then progress to 45-50 minutes a day by six weeks.
High-intensity IMT plus walking: The IMT intensity will be set at 60% of PImax which will be adjusted weekly and nose clip will be used. Frequency: 5x/week; 1x/day preferred. 6 Interval Levels: (6 efforts at each level): (1) 60s rest interval; (2) 45s rest interval; (3) 30s rest interval; (4) 15s rest interval; (5)10s rest interval; (6) 5s rest interval, trained to exhaustion.

Low-intensity IMT Plus Walking
n=3 Participants
For the low-intensity Inspiratory Muscle Training (IMT), the intensity was set at 15% maximal inspiratory pressure (PImax), which was considered "Sham training"..
The walking program consisted of walking at an intensity of "hard" to "somewhat hard" on the Borg's Rating of Perceived Exertion scale. Participants were encouraged to walk at 15 minutes once to twice a day initially, then progress to a total of 45-50 minutes a day, if they could tolerate, by the end of six weeks. Every participant was given a pedometer and a polar heart rate monitor to track step counts and walking heart rate.
The IMT training is about 15-20 minutes. Both groups came to our facility once a week for 15 to 20 minutes for discussions about their progress and readjustment of the training intensity on the IMT breathing device.

SECONDARY outcome
Timeframe: Baseline and 6 WeeksThe six-minute walk test is a measure of cardiovascular endurance which measures how far a person can walk in 6 minutes. This test was conducted twice respectively at pre-training and at post-training to account for potential learning effect. A longer distance walked on the six-minute walking test indicates a better cardiovascular endurance.
