Study summary

Overweight is a risk factor for a number of non-communicable diseases, and this risk doubles, if an individual is physically inactive. Various exercise interventional protocols in the past have been reported on treating overweight and obesity which helps to decrease the different anthropometric variables. Despite all these protocols, obese and overweight do not seem to benefit greatly by these exercise training programs, as lack of time is thought to the main reason for not engaging in healthful physical exercise. Research evidence has proven that people with a body mass index of more than 30 kg/m2 and waist circumference of more than 102 cm have 2-fold higher risk of waking fewer steps daily. Although physical exercise is thought to be very helpful in regulating the body weight, it is very important to identify the type of physical activity to effectively manage overweight and obesity. Aerobic exercise namely high intensity interval training have been reported to reduce the body mass, fat%, and waist circumference. Investigators believe that high intensity interval training would help in controlling the various anthropometric variables namely the body mass index, waist circumference, and fat% in trunk region in physically inactive overweight adults.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2021 to primary completion in Nov 2021, 5 months.

Of 1,356 non-industry interventional studies with no phase under Overweight, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 38. This study's 5 months is below that.

Counting every sponsor, half of 1,472 studies reached it within 17 months; a quarter within 7 and three quarters within 36.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 20, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
