Effect of Aerobic Interval Training With Vitamin D Supplement on Functional Capacity and Perceived Myalgia

Study Overview
=================
Brief Summary
-----------------
This study aimed to investigate whether there will be an effect of adding a program of aerobic interval training in managing patients suffering from myalgia associated with vitamin D deficiency.

Detailed Description
-----------------
Forty five women complaining from myalgia with vitamin D deficiency participating in this study. Their ages are ranged from 30 to 40 years. They are assigned randomly into three groups: Group (A): included 15 patients who are participating in an aerobic interval training exercise program with vitamin D supplementation (cholecalciferol 400 IU/day). Group (B): included 15 patients who are receiving vitamin D supplementation only (cholecalciferol 400 IU/day). Group (C): included 15 patients who are participating in an interval training exercise program only. The intervention will last for 12 weeks

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Group (A)<br>Included 15 patients who are participating in an aerobic interval training exercise program with vitamin D supplementation (cholecalciferol 400 IU/day). The aerobic interval training is conducted for one hour, three days per week on a total period of 12 weeks. | Other: aerobic interval training and Vitamin D supplementation,<br>* The participants in both groups A will be instructed to perform aerobic interval exercises at 70% maxHR for 5 minutes and then decrease activity to 50% for 5 minutes and repeat for the length of the activity (the training will be done by using bicycle ergometer(Biodex LBC, Biodex Inc., New York).• Before starting training ; Maximum heart rate calculated from the following equation: maxHR= 220-age . Duration: the first five to ten minutes of each session were dedicated to warming up exercise on the bicycle in the form of slow progression exercise (to decrease the risk of hypotension, musculoskeletal injury and cardiovascular complications), followed by the active phase of exercise for 40 min., and finally cooling down phase for ten minutes. with intensity and speed decreased gradually until reaching the resting HR Frequency: 3 days/week., for 12 weeks Also all participants in this group are taking gne capsule containing (cholecalciferol 400 IU) every day .<br>|
| Experimental: Group (B)<br>Included 15 patients who are receiving vitamin D supplementation only . One capsule containing (cholecalciferol 400 IU) was taken every day for 12 weeks | Drug: Vitamin D supplementation only<br>* One capsule containing (cholecalciferol 400 IU) was taken every day .<br>|

Frequency: 3 days/week. The whole training lasting for 12 weeks<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Concentration of Plasma Serum vitamin D level (25OHD) | It is performed by Laboratory BioPlex® 2200 System | It is performed before and after the study(12 weeks interval) for all groups | 
| Description of Functional capacity efficiency | Cooper 12-Minute Walk Test (12MWT) | It is performed before and after the study(12 weeks interval) for all groups | 
| Intensity of non specific muscle pain (myalgia) | A 10-cm Visual Analogue Scale (VAS) was used to evaluate the patients' pain , with 0 representing no pain and 10 representing the worst pain imaginable | It is performed before and after the study(12 weeks interval) for all groups | 
| Description of the improvement in Quality of life | The Short form health survey (SF-12)is often used to compare health status between groups of patients, to indentify predictors of health status | It is performed before and after the study(12 weeks interval) for all groups |
