END-HEMO: Could Physical Activity Help to Counteract the Blood Haemophilia Disturbance? A Pilot Study.
Study Details
Study Description
Brief Summary
Physical activity is lower in patients with haemophilia than in their healthy peers. Nevertheless, exercize is recommended for those patients and supported by evidence. Until 2013, scientific and medical evidence to encourage physical activity for patients with haemophilia were listed to increase their locomotor function, their metabolic status, their fitness level and their well-being. In 2013, an original publication by Groen et al. suggested that physical activity could also interact with the specific and biological disturbance of the disease.
We propose to consider that regular endurance exercize prescription should be encouraged in patients with haemophilia not only for a healthier lifestyle but also because it could positively alter the specific biological blood disturbance seen in haemophilia. Nevertheless, before planning a well powered intervention trial we need to determine the acceptability of regular exercize and the expected value of factor Factor VIII, von Willebrand factor and von Willebrand propeptide after an endurance training program.

Experimental: Haemophilia A patients Patients will perform endurance training program on 6 consecutive weeks |
Other: Endurance training program
Exercise intensity will be fixed to the corresponding powers for ventilatory thresholds, if applicable for pain tolerance. The endurance interval training workout is known to induce metabolic and physiological adaptations. For intermittent workout training protocol, recovery periods at moderate intensity between periods at high intensity help to sustain repeated high intensity periods of exercise. If pain disturbs exercise tolerance, power will be lowered as necessary.
A set of 3 training sessions per week of 45 minutes each for 6 consecutive weeks will be proposed (one session every two days). This scheme is usually encouraged for patients suffering from chronic diseases.

Outcome Measures
Primary Outcome Measures
- Determine the acceptability of a 6-weeks endurance training program in patients with haemophilia A as assessed by specific clinical follow-up [During 6 weeks]
Secondary Outcome Measures
- Variation of Factor VIII in response to acute exercise before and after the endurance training program as assessed by specific bioassay [Day 1 and after 6 weeks of training program]
- Variation of von Willebrand Factor in response to acute exercise before and after the endurance training program as assessed by specific bioassay [Day 1 and after 6 weeks of training program]
- Variation of von Willebrand propeptide in response to acute exercise before and after the endurance training program as assessed by specific bioassay [Day 1 and after 6 weeks of training program]
- Variation of maximal oxygen uptake in response to acute exercise before and after the endurance training program as assessed by specific endurance testing [Day 1 and after 6 weeks of training program]
- Variation of VO2max in response to acute exercise before and after the endurance training program as assessed by specific endurance testing [Day 1 and after 6 weeks of training program]
- Variation of quality of life of patients in response to acute exercise before and after the endurance training program as assessed by Haem-A-QoL questionnaire [Day 1 and after 6 weeks of training program]
The Haem-A-QoL questionnaire was specifically designed for adults with haemophilia
