Trial summary

Previous studies have demonstrated that resistance training (RT) is beneficial to increase muscle strength, improve functional ability and the ability to rapidly produce force, known as the contractile rate of force development (RFD) in older adults. Read more about this study

About this study

Previous studies have demonstrated that resistance training (RT) is beneficial to increase muscle strength, improve functional ability and the ability to rapidly produce force, known as the contractile rate of force development (RFD) in older adults. However, much less research has focused on the effect of RT on the lower extremity muscle strength, contractile RFD and impulse in middle-aged and older people with musculoskeletal conditions, especially for osteoporosis (OP) (or osteopenia) or knee osteoarthritis (KOA). Therefore, the purpose of this study was to investigate the effect of RT on the lower extremity muscle strength, RFD and impulse in middle-aged and older people with musculoskeletal conditions, especially for OP and knee OA (KOA). The investigators hypothesized that such a training program would lead to induce not only specific muscle strength enhancement but also an increment in contractile RFD and impulse.

Read the detailed description

Osteoporosis (OP) and osteoarthritis (OA) are the two most common musculoskeletal conditions in older adults, causing high healthcare costs and negative effects on quality of life. Previous studies have reported that OP and OA has a strong association with sarcopenia, a term defined as age-related involuntary loss of skeletal muscle mass and strength or function.A decline of muscle mass and strength in older adults may limit a variety of activities of daily living (ADLs) and increase morbidity and mortality. However, many ADLs often involve faster limb movements with contraction times of 50 - 200 ms (i.e. sit-to-stand performance and avoiding falls). Therefore, in addition to muscle mass and strength, the ability to rapidly produce force, known as the contractile rate of force development (RFD), and the area under the force-time curve, defined as contractile impulse, seem to be important to adequately characterize the performance of ADLs in older adults. Typically, resistance training (RT) is often prescribed to increase muscle strength, improve functional ability and eliminate much of age-associated muscle atrophy and weakness in a healthy population. Other studies have also shown that implementation of RT can help improve RFD in healthy young and elderly individuals following RT. However, it still unclear that the effect of RT on contractile RFD and impulse in middle-aged and older people with musculoskeletal conditions. Therefore, the aim of this study was to examine the effects on the lower extremity muscle strength, contractile rate of force development (RFD), impulse in middle-aged and older people with osteoporosis (OP)(or osteopenia) or knee osteoarthritis (KOA) after 12 weeks of resistance training.

What is being measured

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

  1. Maximum voluntary contraction (MVC)

    Muscle strength was measured as maximum voluntary contraction (MVC) of the quadriceps exerted on an isokinetic dynamometer.

    Measured: three months

Secondary outcomes (2)
  1. Contractile rate of force development (RFD)

    Contractile rate of force development (RFD) was derived as the average slope of the initial phase of the torque-time curve (change in torque/change in time) at 0-30, 50, 100, and 200 ms relative to the onset of contraction.

    Measured: three months

  2. Impulse

    Contractile impulse was determined as the area under the torque -time curve in the same time intervals of 0-30, 0-50, 0-100, and 0-200 ms relative to the onset of contraction.

    Measured: three months

Questions about this trial

What is this clinical trial studying?

A study testing hydraulic resistance circuit training in people with Osteoporosis and Osteoarthritis, run by Far Eastern Memorial Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Dec 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum voluntary contraction (MVC) (time frame: three months). 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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Dec 2013.
