Brief Summary

The aims of this project are to compare the effects between 8-week moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT) on improving HRV.

Conditions

Fat Burn; Exercise

Keywords

heart rate variability; visceral adipose tissue; exercise

Outcome Measures

Primary Outcomes (1)

• visceral adipose tissue

  explore which modality of exercise can reduce the greatest area of visceral adipose tissue under body compostion analyzer measurement

  four times (baseline, 8-week, 16-week, 24-week)

Secondary Outcomes (1)

• heart rate variability

  four times (baseline, 8-week, 16-week, 24-week)

Study Arms (2)

MICT to HIIT

EXPERIMENTAL

participants will receive moderate-intensity continuous training lasting 8 weeks, and then exchange to high-intensity interval training lasting 8 weeks, with 8 weeks rest insert to two different modalities of exercise.

Behavioral: exercise

HIIT to MICT

EXPERIMENTAL

participants will receive high-intensity interval training lasting 8 weeks, and then exchange to moderate-intensity continuous training lasting 8 weeks, with 8 weeks rest insert to two different modalities of exercise.

Behavioral: exercise

Interventions

exercise BEHAVIORAL

the exercise consists of two different modalities: moderate-intensity continuous training (MICT): the main MICT program will be designed to last 30 minutes. The MICT will be designed to involve core muscle training (e.g., march, step touch, lunge, V-step, box step, twist, knee up, scoop, and scissors). high-intensity interval training (HIIT): The HIIT motions will be a mix of spiderman mountain climbers, standing oblique crunches, squats, froggers, jumping jacks, foot fire, jump squats, and mountain climbers. A total of four sets will be performed with 1-minute rests between sets. Each set comprises eight motions, with each motion lasting 30 seconds and a rest interval of 10 seconds between motions. Participants in the HIIT group will perform the most repetitions possible within 30 seconds.

Eligibility Criteria

• Age: 40 Years - 64 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Community residents (a) who are 40-64 years old, (b) with a VAT of ≧ 100 cm2 measured using a body composition analyzer, and (c) who can communicate in Mandarin or Taiwanese will be included.

You may not qualify if:

• This study will exclude (a) residents with recent unstable conditions (stroke, cardiovascular and respiratory diseases, handicap, pregnancy, mental disorders, systolic blood pressure \> 200 mmHg, or diastolic blood pressure \> 110 mmHg), (b) residents with contraindications to body composition analyzer measurement (e.g., people with pacemakers, artificial metal joints, and amputated hands or feet) and residents who cannot stand during testing, and (c) residents with habits or lifestyles that may affect HRV (e.g., smoking or alcohol abuse and shift work).
