In this study, when performing aerobic and anaerobic exercise with EX1 applied to normal adults between the ages of 19 and 65. The purpose of this study was to determine the effect on the muscle activity of the trunk and lower extremities compared with and without EX1.
In this study, aerobic exercise and anaerobic exercise for normal adults were divided into two visits for a total. For aerobic exercise, the investigators compared the aerobic treadmill walking program without EX1 \[30 minutes of moderate (64-76% HRmax, 12-14 of RPE) aerobic treadmill walking, 40 minutes including warm-up and cool-down times\], the aerobic treadmill walking program with EX1 \[30 minutes of moderate (64-76% HRmax, 12-14 of RPE) aerobic treadmill walking, 40 minutes including warm-up and cool-down times\] , and the high-intensity interval exercise (HIIT) program with EX1 \[High-intensity-low-intensity interval walking exercise was performed at treadmill speed (High: 90-95% HRmax, 15-17 of RPE/Low: 60-70% HRmax, 9-11 of RPE) and EX1 resistance strength (High: resistance intensity 7- 9/Low: Resistance strength 0-2)\] to check the effect on muscle activity, heart rate, and respiratory metabolic energy consumption rate.

Reduction on muscle activity (%MVC)
\[aerobic\] All subjects underwent measurements of the trunk and lower extremity muscle activity (%MVC) during aerobic treadmill walking and measured by three conditions (①Aerobic treadmill walking program without EX1, ②Aerobic treadmill walking program with EX1, and ③High-intensity interval exercise (HIIT) program with EX1. \[anaerobic\] All subjects underwent measurements of the trunk and lower extremity muscle activity (%MVC) during each condition
Time frame: 3hours/2hours
Reduction on metabolic energy expenditure (ml·kg-1·min-1)
\[aerobic\] All subjects underwent measurements of respiratory metabolism energy (ml·kg-1·min-1) during aerobic treadmill walking and measured by three conditions (①Aerobic treadmill walking program without EX1, ②Aerobic treadmill walking program with EX1, and ③High-intensity interval exercise (HIIT) program with EX1.
Time frame: 3hours
Reduction on heart rate (beats per minute, bpm)
\[aerobic\] All subjects underwent measurements of heart rate (bpm) during aerobic treadmill walking and measured by three conditions (①Aerobic treadmill walking program without EX1, ②Aerobic treadmill walking program with EX1, and ③High-intensity interval exercise (HIIT) program with EX1.
Time frame: 3hours
Distinction on muscle activity (%MVC)
\[aerobic\] Exercising with EX1 results in higher muscle activity than exercising without wearing EX1.
Time frame: 3hours
Distinction on metabolic energy expenditure (ml·kg-1·min-1)
\[aerobic\] Exercising with EX1 consumes more energy for the same amount of time than exercising without wearing EX1.
Time frame: 3hours

Distinction on heart rate (beats per minute, bpm)
\[aerobic\] Exercising with EX1 shows a higher heart rate for the same time than exercising without EX1.
Time frame: 3hours
Distinction on muscle activity (%MVC)
\[anaerobic\] Fitness movements using EX1 generate more muscle activity than exercise without EX1.
Time frame: 2hours
