Study summary

Background: Hypertension has long been considered as a major risk factor for cardiovascular disease representing a high public health concern.

Objectives: the purpose of this study is to evaluate the effects of combined HIIT and resistance training on body composition, blood pressure, and cardiorespiratory fitness in obese hypertensive men.

Methods: This study will make use of sixty obese hypertensive men aged 40 to 60 years. All participants meeting the eligibility criteria will be assigned to one of three groups; combined HIIT and resistance group, HIIT only group or control group. Combined exercise group subjects will undergo weekly three sessions of both HIIT and resistance training for sixteen weeks. The HIIT session will involve four four-minute high-intensity intervals with an intensity of at 80-95% of the HRmax interspersed with two-minute active recovery intervals with intensity of 40% to 60% of the HRmax. The resistance training session will be composed of eight exercises perform 3 sets of 8-12 repetitions with an intensity of 80% of the subject's estimated 1-RM. The HIIT only group perform 12 weeks of HIIT only. The control group subjects will be instructed not to change their usual daily physical activities routine and instructed to abstain from practicing any exercise regimens during the 12-week study period. Body composition measures, blood pressure and VO2peak will be assessed at baseline and at the end of the study period.

Results: All the outcome variables will be assessed at baseline and 12 weeks following the treatment period.

Inclusion criteria

  • men aged between 40 and 60 years old,
  • have been diagnosed with clinical stage 1 or 2 hypertension,
  • being obese with more than 30 kg/m2
  • physically inactive

Exclusion criteria

Exclusion Criteria:

  • musculoskeletal problems that may limit their ability to participate in resistance or HIIT programs
  • diabetes mellitus
  • a history of respiratory or chronic heart disease
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

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

Started Apr 2025 (actual). Primary completion is estimated for Jul 2025, 3 months after the start.

Of 1,403 non-industry interventional studies with no phase under Hypertension, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 41. This study's planned 3 months is below that.

Counting every sponsor, half of 1,498 studies reached it within 23 months; a quarter within 10 and three quarters within 41.

How these figures are worked out, and which studies are left out of them.

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 Jun 4, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
