About this study

Official title: Effects of Vitamin D Supplementation in Muscle Strength and Postural Balance Training in Vulnerable Elderly Women

Introduction: In Brazil, a person who is sixty years old or more is considered elderly. The incidence of osteoporosis and osteopenia has been increasing, as have fractures resulting from falls. Vitamin D deficiency can cause muscular atrophy in type II fibers (fast contraction and strength), which can increase the risk of falls. The aging process produces reduction in the ability of postural control system to maintain postural balance, which may increase postural instability and consequently increase the elderly risk to falls. Objective: To evaluate if vitamin D supplementation associated with regular exercise in vulnerable older women improves muscle strength and postural balance in 12 weeks. Methods: This will be a randomized prospective clinical trial, double blind, placebo-controlled intervention. Will be part of the study 40 elderly women vulnerable, who meet the inclusion criteria and that will be coming from the community through calls made by radio and social network. The volunteer will undergoing to blood test, body composition and bone mineral density, Mini Mental State Examination, Geriatric Depressive Scale, Falls Efficacy Scale, WHOQOL-OLD and WHOQOL-BREF instruments, functional capacity tests (MiniBEST, Time up and Go, Chair Rising Test, Six-minute walk test), muscular strength assessment (isokinetic dynamometry, handgrip and 1RM test) and postural balance (AccSway force platform for static postural balance and NeuroCom's Balance Master for dynamic postural balance) before and after 12 weeks of intervention with vitamin D supplementation and resistance and postural balance exercise. The intervention that will be perform during the 12 weeks with a progressive resistance training program.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Postural balance - semi static - change

    Evaluation of postural balance - AccSway force platform for semi static postural. The arithmetic mean of the results was calculated from the three tests conducted under each condition, and was processed using the Balance Clinic software. The following parameters were used to measure the stability of the participants: medial-lateral and anteroposterior amplitude (cm), the mean velocity calculated from the total displacement of the center of pressure (COP) in all directions (cm/s), and the elliptical area encompassing 95% of the displacement from the COP (cm2). The following parameters were used to measure the stability of the participants: medial-lateral and anteroposterior amplitude (cm), the mean velocity calculated from the total displacement of the center of pressure (COP) in all directions (cm/s).

    Measured: This measure will be performing before; after the innervation (12 weeks strength and postural balance exercise) and six months after the intervention (six months follow up).

Secondary outcomes (5)
  1. Postural balance - dynamic - change

    Evaluation of dynamic postural balance - The postural balance assessment (posturography) will be perform on the NeuroCom Balance Master® force platform system (NeuroCom International, Inc., Clackamas, OR, USA). The variables will be the mean sway speed (cm/s) on a stable surface and an unstable surface; and the mean sway in the anteropoterior direction and mediolateral (cm) direction at the same conditions. The variables will be the mean weight transfer index (%), mean movement time (s) and mean impact index.

    Measured: This measure will be performing before; after the innervation (12 weeks strength and postural balance exercise) and six months after the intervention (six months follow up).

  2. Muscular strength - Hand Grip - change

    Evaluation of muscular strength improvement- hand grip strength (HGS). HGS assessment was performed using a Jamar hand dynamometer, measured in kilograms (kg), which is adopted by the American Society of Hand Therapists (ASHT).

    Measured: This measure will be perform before and after the intervation (12 weeks strenght and potural balance exercise).

  3. Muscular strength - Isokinetic dynamometry - change

    Evaluation of muscular strength improvement - Isokinetic dynamometry will be use to determine knee extension and flexion strength using the Biodex Multi-Joint System 3 (Biodex MedicalTM, Shirley, NY, USA). The isokinetic variables used were maximum peak torque corrected for body weight (%), and total work (J).

    Measured: This measure will be performing before; after the innervation (12 weeks strength and postural balance exercise) and six months after the intervention (six months follow up).

  4. Muscular strength - 1 maximal repetition (RM)- change

    Evaluation of muscular strength improvement - 1RM test. One-repetition maximum in weight training is the maximum amount of force that can be generated in one maximal contraction (kg).

    Measured: This measure will be performing before; after the innervation (12 weeks strength and postural balance exercise) and six months after the intervention (six months follow up).

  5. Body composition and bone mineral density - change

    Evaluation of body composition (area=cm2; BMC=g and BMD=g/cm2) and bone mineral density (BMD=g/cm2; T-score)

    Measured: This measure will be performing before; after the innervation (12 weeks strength and postural balance exercise) and six months after the intervention (six months follow up).

What does the primary outcome measure?

Postural balance - semi static - change (time frame: This measure will be performing before; after the innervation (12 weeks strength and postural balance exercise) and six months after the intervention (six months follow up).). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
