Brief Summary

Obesity is a global health concern associated with an increased risk of cardio-metabolic diseases and reduced overall health. Exercise is a proven modality for managing obesity, with current focus of researches on identifying more time-efficient modes of exercise training. REHIT and HIIT have proven benefits but comparative effects of REHIT and HIIT in overweight and obese adults is yet to be determined. Hence the objective of this study is to compare the effects of reduced exertion high intensity training (REHIT) versus high intensity interval training (HIIT) on anthropometric measures (weight, waist circumference, hip circumference, waist-to-hip ratio), CUN-BAE adiposity index and cardiorespiratory fitness in overweight and obese adults.

Conditions

Overweight and Obesity

Outcome Measures

Primary Outcomes (5)

• Waist circumference

  Will be measured using a cloth tape measure. Waist circumference will be measured at the level of the smallest circumference above the umbilicus and below the xiphoid appendix.

  6 weeks

• Hip Circumference:

  Measure at the widest point of the hips, with feet together

  6 weeks

• Waist-to-hip Ratio:

  To determine the waist-to-hip ratio, divide the WC by the HC

  6 weeks

• Cardiorespiratory fitness

  Cardiorespiratory Fitness will be assessed via Queens College step test.

  6 weeks

• Adiposity index

  Evaluation will be done using CUN-BAE INDEX (Clínica Universidad de Navarra-Body Adiposity Estimator)

  6 weeks

Study Arms (2)

Reduced Exertion High intensity Training (REHIT) Group

EXPERIMENTAL

Participant will perform a 5 min warm-up exercises then do cycling or treadmill running for 20 min at 40%-60% of HRR and then will conclude with 5 min cool down exercises. From week 2 to 6 participants will be instructed to perform training sessions on a cycle ergometer.A 3-minute cool-down period will conclude each session. Patients in this group will be provided with a caloric restriction plan by a nutritionist that will be followed throughout the training duration.

Other: Reduced Exertion High Intensity Training (REHIT)

High Intensity Interval Training (HIIT)

EXPERIMENTAL

Participant will perform a 5 min warm-up exercises then do cycling or treadmill running for 20 min at 40%-60% of HRR and then will conclude with 5 min cool down exercises. From week 2 to 6 participants will be instructed to perform a warm up of 5 min, then 4 bouts of 4 min of HIIT will be performed at 80%-95% of HRR separated by 3-min active recovery periods of moderate intensity cycling at 60%-70% of the HRR followed by 5 min cool down exercises. Patients in this group will be provided with a caloric restriction plan by a nutritionist that will be followed throughout the training duration.

Other: High Intensity Interval Training (HIIT)

Interventions

Reduced Exertion High Intensity Training (REHIT) OTHER

Participant will perform a 5 min warm-up exercises then do cycling or treadmill running for 20 min at 40%-60% of HRR and then will conclude with 5 min cool down exercises. From week 2 to 6 participants will be instructed to perform training sessions on a cycle ergometer. Each session will consist of a 3-minute warm-up period followed by two 20-second all-out sprints interspersed with 3 minutes of slow pedaling for recovery. Total of 18 sessions of REHIT will be performed thrice a week on alternate days by the participants for consecutive 6 weeks.

Reduced Exertion High intensity Training (REHIT) Group

High Intensity Interval Training (HIIT) OTHER

Patients in this group will be provided with a caloric restriction plan by a nutritionist that will be followed throughout the training duration. Week 1 will be baseline fitness level and familiarization week. Participant will perform a 5 min warm-up exercises then do cycling or treadmill running for 20 min at 40%-60% of HRR and then will conclude with 5 min cool down exercises. From week 2 to 6 participants will be instructed to perform a warm up of 5 min, then 4 bouts of 4 min of HIIT will be performed at 80%-95% of HRR separated by 3-min active recovery periods of moderate intensity cycling at 60%-70% of the HRR followed by 5 min cool down exercises. Pre and post session vitals will be noted. Total of 18 sessions of either HIIT will be performed thrice a week on alternate days by the participants for consecutive 6 weeks.
