High-intensity Interval Training in Patients With Fibromyalgia

Clinicaltrials.gov identifier NCT03924960

Recruitment Status Completed

First Posted April 23, 2019

Last update posted March 17, 2020

Study Description

Brief summary:

Fibromyalgia is a common rheumatic disease characterized by widespread musculoskeletal pain, tenderness, fatigue, sleep disorders, cognitive and somatic complaints. Patients often suffer many somatic and psychological symptoms which contributes negative effect on the health- related quality of life, physical performance and physical activity. Recently, the European League Against Rheumatism presented evidence based recommendations for the management of the fibromyalgia. Accordingly, prompt diagnosis and patient education is required for optimal management. A graduated approach with the aim of improving health-related quality of life should be followed. It should focus first on non-pharmacological modalities and the only "strong for" evidence-based recommendation was the use of aerobic and strengthening exercise. Aerobic exercise with moderate intensity (60 to 70% of age-adjusted predicted maximum heart rate (maxHR)) with a frequency of two or three times per week for at least 4 to 6 weeks for a reduction of symptoms is recommended in the management of fibromyalgia. Low-intensity aerobic exercise (<50 % maxHR) is founded ineffective. In recent years, high intensity interval training (HIIT) is used as popular instead of moderate intensity continuous exercise training (MICT) in cardiac rehabilitation units. It is found superior to moderate intensity exercise in improving cardiovascular fitness as increases maximal oxygen consumption (VO2max). The investigators hypothesis is that 6 weeks of five weekly sessions of HIIT will show superior effect reducing the impact of fibromyalgia and improving pain degree, functional capacity and health-related quality of life in women with fibromyalgia compared to MICT.

Detailed Description

Fibromyalgia is a common rheumatic disease characterized by widespread musculoskeletal pain, tenderness, fatigue, sleep disorders, cognitive and somatic complaints. Patients often suffer many somatic and psychological symptoms which contributes negative effect on the health- related quality of life, physical performance and physical activity. Recently, the European League Against Rheumatism presented evidence based recommendations for the management of the fibromyalgia. Accordingly, prompt diagnosis and patient education is required for optimal management. A graduated approach with the aim of improving health-related quality of life should be followed. Pharmacotherapy is only recommended for severe pain and sleep disturbances. It should focus first on non-pharmacological modalities and the only "strong for" evidence-based recommendation was the use of aerobic and strengthening exercise. Aerobic exercise with moderate intensity (60 to 70% of age-adjusted predicted maximum heart rate (maxHR)) with a frequency of two or three times per week for at least 4 to 6 weeks for a reduction of symptoms is recommended in the management of fibromyalgia. Low-intensity aerobic exercise (<50 % maxHR) is founded ineffective. In recent years, high intensity interval training (HIIT) is used as popular instead of moderate intensity continuous exercise training (MICT) in cardiac rehabilitation units. It is found superior to moderate intensity exercise in improving cardiovascular fitness as increases maximal oxygen consumption (VO2max). While the moderate intensity continuous aerobic exercise program lasts 30 to 60 minutes, HIIT contains 4-6 cycles of 1-4 minutes with a maximum effort and lasts approximately 20 minutes in total. Therefore, another advantage of HIIT is the need for a shorter time to achieve similar or greater effects compared to MICT. The investigatorshypothesis is that 6 weeks of five weekly sessions of HIIT will show superior effect reducing the impact of fibromyalgia and improving pain degree, functional capacity and health-related quality of life in women with fibromyalgia compared to MICT. Therefore, the aim of this study is to assess the effects of HIIT versus MICT on pain, functional capacity and quality of life in women with fibromyalgia.

Arms and interventions
Arm Intervention/treatment
Experimental: High-intensity interval training
Participants in this group will perform a 20-25 minutes of aerobic exercise with a maximum capacity of 3-4 minutes (HRmax 80-95%) and active recovery for 3-4 minutes (HRmax 30-50%), five exercise sessions per week for 6 weeks.
Behavioral: High-intensity interval training
Participants in this group will perform a 20-25 minutes of aerobic exercise with a maximum capacity of 3-4 minutes (HRmax 80-95%) and active recovery for 3-4 minutes (HRmax 30-50%), five exercise sessions per week for 6 weeks.
Active Comparator: Moderate-intensity continuous training
Participants in this group will perform a 30-45 minute ergometric cycling exercise at 65-70% of the measured maximum heart rate (HRmax), five exercise sessions per week for 6 weeks.
Behavioral: Moderate-intensity continuous training
Participants in this group will perform a 30-45 minute ergometric cycling exercise at 65-70% of the measured maximum heart rate (HRmax), five exercise sessions per week for 6 weeks.
Other: Control

Outcome Measures
  • Primary Outcome Measures: 1. Fibromyalgia impact questionnaire [ Time Frame: 6 weeks ]
    The FIQ was designed to measure the health status of patients with fibromyalgia.
  • Secondary Outcome Measures: 1. Visual analogue scale [ Time Frame: 6 weeks ]
    Pain intensity was measured with visual analogue scale (0-10mm) which is used to measure musculoskeletal pain with very good reliability and validity.
  • 2. Short- form health survey 36 [ Time Frame: 6 weeks ]
    Short- form health survey 36 contains 36 items which are used to evaluate the quality of life of patients with chronic pain. It measures eight different domains that address physical functioning, physical role limitation, pain, general health, vitality, social functioning, emotional role limitation and mental health. The score of each domain ranges from 0 (worse quality of life) to 100 (best quality of life).
  • 3. Cardiorespiratory fitness [ Time Frame: 6 weeks ]
    A symptom-limited maximal cardiopulmonary exercise test performed on a cycle ergometer at baseline and following six-week exercise intervention to measure maximal oxygen consumption (VO2maximum) (ml/ kg/min).
Eligibility Criteria
  • Ages Eligible for Study: 18 to 65 Years (Adult, Older Adult)
  • Sexes Eligible for Study: Female
