Brief Summary

For the elderly using plyometric training, there are very few studies on strengthening the explosive power of the lower limbs of the elderly. For example, past studies have explored the effect of high-speed and low-speed plyometric training on the improvement of muscle contraction speed in the elderly over 60 years old. From the past researches, the study found that compared with low-speed training, High-speed training can not only improve muscle strength, but also effectively increase muscle speed and improve life functions. However, studies using plyometric training to improve lower body balance in older adults are scarce and the evidence is scant. Therefore, the purpose of this study is to explore the clinical benefits of plyometric training for improving the balance ability of the lower limbs in the elderly.

Outcome Measures

Primary Outcomes (3)

• 30-second sit-to-stand test

  1 Instruct the patient: (1) Sit in the middle of the chair. (2) Place your hands on the opposite shoulder crossed, at the wrists. (3) Keep your feet flat on the floor. (4) Keep your back straight, and keep your arms against your chest. (5) On "Go," rise to a full standing position, then sit back down again. (6) Repeat this for 30 seconds. 2 On the word "Go," begin timing. If the patient must use his/her arms to stand, stop the test. Record "0" for the number and score. 3 Count the number of times the patient comes to a full standing position in 30 seconds. If the patient is over halfway to a standing position when 30 seconds have elapsed, count it as a stand. 4 Record the number of times the patient stands in 30 seconds.

  From enrollment to the end of treatment at 10 weeks

• time up and go test (TUG)

  Patients wear their regular footwear and can use a walking aid, if needed. Begin by having the patient sit back in a standard arm chair and identify a line 3 meters, or 10 feet away, on the floor. 1 Instruct the patient:When I say "Go," I want you to: (1). Stand up from the chair. (2). Walk to the line on the floor at your normal pace. (3). Turn. (4). Walk back to the chair at your normal pace. (5). Sit down again.2 On the word "Go," begin timing. 3 Stop timing after patient sits back down. 4 Record time.

  From enrollment to the end of treatment at 10 weeks

• functional reach test (FRT)

  Ascertaining dynamic balance.In standing, measures the distance between the length of an outstretched arm in a maximal forward reach, while maintaining a fixed base of support. This information is correlated with risk of falling.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: DOUBLE
• Who Masked: CARE PROVIDER, OUTCOMES ASSESSOR
• Masking Details: All subjects were randomly assigned to either the control or experimental group to receive their respective exercise programs. The outcomes assessor was blinded to the group allocation of each participant during baseline and post-intervention assessments. No group assignment information was provided to the care providers.
• Purpose: TREATMENT
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: SPONSOR

Model Details: The experimental group underwent plyometric training three times a week, performing three rounds each session, for a total intervention period of 10 weeks. The control group, on the other hand, engaged in regular exercises during the same intervention period. Before and after the training program, both groups underwent assessments to evaluate their balance abilities, which included the 30-second sit-to-stand test, time up and go test (TUG), functional reach test (FRT), and lower extremity explosiveness test.
