NCT06756230

Brief Summary

In this study; will examine the effects of downhill walking (eccentric exercise training) on exercise capacity, quality of life, and blood lactate levels in individuals with IPF. After the initial assessment, patients will be randomized into two groups: downhill walking PR group and Standard PR Group.

Outcome Measures

Primary Outcomes (2)

  • 6 Minutes Walking Distance (6MWD)

    6 MWD means the distance the patient walked in 6 minute walk test. Its unit is meters.

    Baseline and the end of the 8 weeks exercise program

  • Saint George Quality of life questionnaire

    The St. George's Respiratory Questionnaire (SGRQ) is designed to measure quality of life. Four scores are calculated Symptoms, Activity, Impacts, and Total. Saint George Respiratory Questionaire (SGRQ) score: The SGRQ ranges from 0 (no impairment of quality of life) to 100 (highest impairment of quality of life).

    Baseline and the end of the 8 weeks exercise program

Secondary Outcomes (10)

  • Spirometric measurements (Forced vital capacity)

    Baseline and the end of the 8 weeks exercise program

  • Spirometric measurements (First second forced expiratory volume)

    Baseline and the end of the 8 weeks exercise program

  • Spirometric measurements (FEV1/FVC ratio)

    Baseline and the end of the 8 weeks exercise program

  • Peripheral muscle strength

    Baseline and the end of the 8 weeks exercise program

  • Hand grip strength

    Baseline and the end of the 8 weeks exercise program

  • +5 more secondary outcomes

Study Arms (2)

Downhill Walking PR Group

ACTIVE COMPARATOR

A standard pulmonary rehabilitation (PR) exercise program will be implemented. Downhill treadmill walking will be included during walking sessions.

Other: Pulmonary RehabilitationOther: Downhill Walking

Standard PR group

ACTIVE COMPARATOR

A standard pulmonary rehabilitation (PR) exercise program will be implemented. Walking will be performed on a treadmill without incline.

Other: Pulmonary RehabilitationOther: Treadmill Walking without incline

Interventions

8 weeks, 2 sessions per week, Aerobic training will be provided as treadmill walking. It will be performed either downhill or on a flat treadmill, depending on the group. Warm-up and stretching exercises Resistance exercises will be performed with a load equivalent to 50% of 1 maximum repetition. 10 repetitions will be performed in sets, one set in each session. Based on the differences in the general condition of the patients, different workloads and modifications will be used when creating an exercise program for each patient. Resistance exercises will focus on both upper and lower extremity muscles.

Downhill Walking PR GroupStandard PR group

Treadmill exercise will be applied for 30 minutes in the target heart rate range of 60-80% intensity. The target heart rate method will be used to determine the exercise intensity. Blood pressure, heart rate and Borg Perceived Exertion Scale scores will be monitored during the exercises. Downhill walking training will continue with a constant -10% incline.

Downhill Walking PR Group

Treadmill exercise will be applied for 30 minutes in the target heart rate range of 60-80% intensity. The target heart rate method will be used to determine the exercise intensity. Blood pressure, heart rate and Borg Perceived Exertion Scale scores will be monitored during the exercises. Traditional walking training will initially involve walking with a neutral incline.
