Oxygenation and Muscle Function's Relationship During SLIE in Older Adults

Completed

• Conditions: Oxygenation

• Registration Number: NCT04812288
• Lead Sponsor: State University of New York at Buffalo

Brief Summary

This study is to determine the correlations between oxygenation of calf muscles and physical performance including balance, gait speed, and endurance in older adults by utilizing the NIRS device.

Detailed Description

The aim of this study is to determine the relationship between oxygenation of calf muscles and physical performance including balance, gait speed, and endurance in older adults by utilizing the NIRS device. The investigators want to determine the relationship between different types of tests and oxygenation for older adults with 4 levels of physical activity. This study will help towards identifying possible short and effective exercises for older adults with different activity levels.

Primary Outcome Measures

Name	Time	Method
time to reach the minimum muscular oxygenation level (Only measure one time at a single time point, does not measure changes)	Day1	time to reach the minimum muscular oxygenation level during bilateral heel raise test in seconds
recovery of muscular oxygenation (Only measure one time at a single time point, does not measure changes)	Day1	the muscular oxygenation difference in percentage between the first second and the last second after finishing the bilateral heel raise test for 1 minute

Secondary Outcome Measures

Name	Time	Method
distance finished in the 2-Minute Walking test (Only measure one time at a single time point, does not measure changes)	Day1	This test measures the maximum distance in meters covered in 2 minutes. Longer distance means better endurance.
time to finish the Timed Up and Go test (Only measure one time at a single time point, does not measure changes)	Day1	This test measures time in seconds to finish the Timed Up and Go test from standing from a chair, walking for 3-meter distance, turning around, going back and sitting down. Less seconds means higher mobility. Higher than 12 seconds indicates risk of falls.
Short Physical Performance Battery score (Only measure one time at a single time point, does not measure changes)	Day1	Three parts including balance, gait speed, and chair stand test are measured. Full points of each part is 4. The score range is from 0 to 12 points. Higher score means higher physical function.
the number of heel raise finished within one minute (Only measure one time at a single time point, does not measure changes)	Day1	This test measures the number of heel raise that participants can complete within one minute. More heel raise times means more endurance at the calf muscle.
