The Effect of EX1 Training in Normal Adults

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.

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Healthy adults aged 19 to 65 years without a history of central nervous system disease

Exclusion criteria

  • Those who have difficulty walking independently due to problems such as visual field defects or fractures
  • Those who have difficulty understanding the exercise program due to severe cognitive decline (Korean-Mini-Mental State Examination, K-MMSE≤10)
  • Those who have difficulty participating in exercise programs due to adult diseases such as uncontrolled hypertension and diabetes
  • Those who are at risk of falling while walking due to severe dizziness
  • Those who are less than 140 cm or more than 185 cm in height that is not suitable size for the wearing of the walking assistance robot
  • Those who are overweight based on body mass index (BMI) 35 or higher

Treatment and study plan

aerobic and anaerobic exercises

Device

[aerobic]

  • Aerobic treadmill walking program without EX1
  • Aerobic treadmill walking program with EX1
  • High-intensity interval exercise (HIIT) program with EX1

[anaerobic]

  • Fitness exercise program with EX1

Primary outcomes

  1. Reduction on muscle activity (%MVC)

    Time frame: 3hours/2hours

    [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

Secondary outcomes

  1. Reduction on metabolic energy expenditure (ml·kg-1·min-1)

    Time frame: 3hours

    [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.

  2. Reduction on heart rate (beats per minute, bpm)

    Time frame: 3hours

    [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.

  3. Distinction on muscle activity (%MVC)

    Time frame: 3hours

    [aerobic] Exercising with EX1 results in higher muscle activity than exercising without wearing EX1.

  4. Distinction on metabolic energy expenditure (ml·kg-1·min-1)

    Time frame: 3hours

    [aerobic] Exercising with EX1 consumes more energy for the same amount of time than exercising without wearing EX1.

  5. Distinction on heart rate (beats per minute, bpm)

    Time frame: 3hours

    [aerobic] Exercising with EX1 shows a higher heart rate for the same time than exercising without EX1.

  6. Distinction on muscle activity (%MVC)

    Time frame: 2hours

    [anaerobic] Fitness movements using EX1 generate more muscle activity than exercise without EX1.
