D Vitamine and Whole Body Vibration in Functional Outcomes

Study Overview
=================
Brief Summary
-----------------
Older with Chronic obstructive Pulmonary Disease (COPD) were submitted to chronic whole body vibration training during 03 months, receiving a vitamine D dose for each week or placebo vitamine. This group was compared with healthy older which were submitted to the same intervention.

Official Title
-----------------
D Vitamine Supplementation and Whole Body Vibration Altering Functional Outcomes

Conditions
-----------------
COPD, Aging

Intervention / Treatment
-----------------
* Dietary Supplement: Vitamine D supplementation
* Other: chronic exercise in whole body vibration (WBV)

Eligibility Criteria
-----------------
Inclusion Criteria: Older patients with COPD Both genders Sedentary according to International Physical Activity Questionnaire (IPAQ) short form BMI in between 22.9 and 28 kg/m2. Older patients with COPD should have a clinical-functional diagnosis of the disease according to GOLD (GOLD, 2018), have been ex-smokers and have not used corticosteroids or have used this drug in a stable way for at least one year (without dosage or medication modifications). Older volunteers should be self-referenced healthy or, if they had systemic arterial hypertension or diabetes mellitus, these comorbidities should be controlled by diet or regular medication use. Exclusion Criteria: Older patients with COPD who had episodes of exacerbation in the last three months, those with pulmonary rehabilitation programs in the last year, those who used home oxygen therapy, and patients with COPD-associated comorbidities were excluded. Volunteers of both groups who were taking vitamin D were excluded, as well as the current smokers, although occasional, volunteers with a history of labyrinthitis or thromboembolism, who had undergone surgical procedures of any size in the last year, such as plaques, pins or cardiac pacemakers, those with unconsolidated fractures that used medications that affected bone metabolism or lean mass, or those who had difficulties adapting to the assessment or the training protocol.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Functional capacity | Change in walk distance achieved in metres, measured during the six minute walk test | before and immediately up to 12 weeks in WBV training. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Balance static and dynamic | Change in total scores of Tinetti index, composed by 16 items divided into 2 sections: static balance (9 items) with 16 points and gait or dynamic balance (7 items) with 12 points, summed in a total score of 28 points. Individuals scoring < 26 points have a risk for falling. | before and immediately up to 12 weeks in WBV training. | 
| Gait speed | Change in time in seconds registered in Timed Up and Go test | before and immediately up to 12 weeks in WBV training. | 
| Body composition | Change in electrical bioimpedance measuring the fat mass and lean mass in kilograms each one, in total body | before and immediately up to 12 weeks in WBV training. | 
| Quality of life measure by WHOQOL | Change in total value obtained from WHOQOL-old questionnaire (World Health Organization of Quality Of Life) that evaluate in older the domains: sensory abilities; autonomy; past, present and future activities; social participation; death & dying; and intimacy. The Quality of life needs to improve when it is 1 to 2,9; is regular 3 to 3.9 points; good between 4 up to 4.9 and very good with 5 points. | before and immediately up to 12 weeks in WBV training. | 
| Peripheral strength | Change in mean value obtained from 03 maneuvers of isokinetic contraction in a hand dynamometer (device that measure strength in handgrip), measured in centimeters of water. | before and immediately up to 12 weeks in WBV training. | 
| Respiratory strength | Change in major value obtained after 03 maneuvers in manovacuometer (device that measure manometry for expiratory pressure and vacuum generated for the inspiratory pressure), all in centimeters of water. | before and immediately up to 12 weeks in WBV training. |
