Efficiency of Physical Activity on the Physical Condition of Elderly Women

Not Applicable

Completed

• Conditions: Aging

• Registration Number: NCT01558401
• Lead Sponsor: Universidade Federal de Sao Carlos

Brief Summary

The purpose of this study was to identify the effects and the efficiency of an adapted physical activity program as regards the physical condition of older Brazilian women.

Detailed Description

Although physical activity programs for the elderly have proved to be able to curb harmful changes due to ageing, not all programs show the same effectiveness, even though they are generally regarded as being effective. The existence of a wide variety of programs calls for debate about their outcomes.

Specific research tools and designs can assist in identifying not only program effectiveness but also program efficiency and use in terms of a better physical performance of subjects on carrying out exercises with less effort, influenced by multiple factors, one of them being adherence to the program. These analyses allow the influence of efficiency and the factors that determine it or are associated with it to be tested, and can provide classifications and subgroups to which interventions should be adapted if they are to offer the best service to them in the short and medium term.

Primary Outcome Measures

Name	Time	Method
Efficiency Data Envelopment Analysis (DEA)	1 year	Data Envelopment Analysis (DEA) is a test of operational investigation It was used to determine the relative efficiency of the older women, considered Decision Making Units (DMU). This analysis supports the hypothesis that the outputs do not need to be proportional to the inputs.

Secondary Outcome Measures

Name	Time	Method
Grip strength	1 year	Grip strength was measured using a Sammons Preston Swedley-Type hand dynamometer (Jamar® Bolingbrook IL, 60440). The test was performed three times on the dominant upper limb at 10-second intervals between each run. The grip strength assigned to each participant was the highest of the three values measured. Subjects were guided to hold the grip meter during exhalation without performing the Valsalva maneuver; they were encouraged verbally throughout the test.
Sit-and-Reach Test	1 year	The Sit-and-Reach Test was employed to evaluate the participants' flexibility of the posterior trunk and lower limbs. The movement was performed three times. The flexibility assigned to subjects was the highest value measured.
Static balance	1 year	Static balance was verified by the One-Leg Stance Test with eyes open31. The subjects gazed at a fixed point two meters away for no more than 30 seconds, with one leg bent at the knee. The test was done three times with open and closed eyes and for both legs, taking into account for each condition (open or closed eyes) the mean value of the measures.
Dynamic balance	1 year	Dynamic balance was evaluated by the Maximum Gait Velocity (MGV). The subjects were instructed to walk along a 33.3cm-wide and 3.33m-long band painted on the floor in the shortest possible time. The test was performed three times. The dynamic balance value assigned to each subject was the mean time walking along the band.
VO2max	1 year	The Rockport 1-Mile Walk Test was used to determine the subjects' physical condition estimated by the VO2max
