About this trial

Muscle fatigue is one of the clinical symptoms in elderly people and demonstrates task dependency and muscle dependency. Muscle fatigue has been shown to negatively impact postural control, physical activity, and quality of life. However, the evidence for the influence of muscle fatigue on postural control is limited and inconsistent in elderly people. Therefore, this study aims to investigate the impacts of aging and muscle fatigue on postural control and gait performance with fatiguing exercises of upper and lower extremities.

Trial outcomes

Primary outcomes

1

Maximal force

The maximal force of upper and lower extremity muscles

Time frame
Baseline (pre-fatigue protocol) and immediately after the fatigue protocol
2

Walking speed

The time taken by participants to walk a standardized distance

Time frame
Baseline (pre-fatigue protocol) and immediately after the fatigue protocol
3

Step Length

The linear distance between the two ankles, typically expressed in centimeter(cm).

Time frame
Baseline (pre-fatigue protocol) and immediately after the fatigue protocol
4

Cadence

The number of steps taken per minute (SPM)

Time frame
Baseline (pre-fatigue protocol) and immediately after the fatigue protocol

Secondary outcomes

1

Oxygenated hemoglobin

Oxygenated hemoglobin is the amount of hemoglobin bound to oxygen, reflecting tissue oxygen availability. It's expressed as the percentage.

Time frame
Baseline (pre-fatigue protocol), during the fatigue protocol, and immediately after the fatigue protocol.
2

Total hemoglobin

Total hemoglobin is the combined amount of oxygenated and deoxygenated hemoglobin, reflecting overall blood volume in the tissue.

Time frame
Baseline (pre-fatigue protocol), during the fatigue protocol, and immediately after the fatigue protocol.
3

Deoxygenated hemoglobin

Deoxygenated hemoglobin is the amount of hemoglobin not bound to oxygen, reflecting oxygen extraction by tissues. It's expressed as the percentage.

Time frame
Baseline (pre-fatigue protocol), during the fatigue protocol, and immediately after the fatigue protocol.
