Clinical Power Testing Across Human Lifetime

September 10, 2019 updated by: Joseph Signorile, University of Miami

Optimal Manner of Measuring Power Across the Lifespan

We will determine when to transition from the common vertical jump to chair stand depending on age and physical activity levels.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Assessing individuals' power, while it is useful in measuring fitness and performance levels, often requires expensive materials. Vertical jump height has been used to assess peak power output using specific regression equations. The issue with this test, although it is often used with older persons, is that it is not practical or useful in assessing the power output in elderly adults due to possible injury risk and lack of familiarity with providing a maximal jump performance. Power is important for elderly adults; because, higher power output in elderly adults has been shown to highly correlate with overall functionality, the ability to do activities of daily living (ADL), and a reduction in fall probability. A recent study examined the capacity of a regression equation to quantify power in elderly adults using a sit-to-stand test and determined; however, the sit-to-stand lacks the difficulty and exhibits a ceiling effect in younger individuals. Therefore, this study will attempt to determine when to transition from the vertical jump to the sit-to-stand, so that the differences in chronological versus physiological age may be determined during aging, and conversely, during improvements through physical or other interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
30 second stand-up test
Time Frame: 5 minutes
The subject will alternate standing a sitting as many times as possible in the 30 second time frame. Wattage (power) will be computed using the equation by Smith et al., Clin Interventions on Aging, 2010.
5 minutes
Countermovement jump test
Time Frame: 5 minutes
The subject will begin in a standing position, quickly lower the body to a self-determined angle an reach as high as possible. Jump height will be determined by subtracting the height of the jump from standing reach. The power is computed using the Lewis formula.

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 25, 2017

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
