Study summary

Spot reduction, referring to local body fat reduction, pertains to subcutaneous adipose tissue utilization from specific body parts during exercise. Its existence has been keenly debated, although generally accepted not to occur during exercise. However, it is based on not only equivocal data - commonly the training protocol typically applied is based on strength rather than endurance training. The investigators sought to test this assumption by utilizing endurance based exercise controlling for energy expenditure and using dual x-ray absorptiometric measures to assess body composition before and after training.

Inclusion criteria

  • males
  • ≥ 30 years old
  • classified as overweight ( ≥ 25 kg ∙ m-2)
  • not participating in regular physical training

Exclusion criteria

Exclusion Criteria:

  • \< 30 years old
  • \< 25 kg ∙ m-2
  • participating in regular physical training
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.

Study arms

  • Experimental
    abdominal aerobic endurance exercise

    Subjects were combining treadmill running at 70% HRmax (27 minutes) with 4x4minutes (30-40% maximal strength, 1RM) of torso rotation and abdominal crunches (57 minutes), 4 d per wk for 10 weeks

    Other: Abdominal aerobic endurance exercise

  • Active comparator
    Control group

    Subjects performed only treadmill running (45 minutes) at 70% HRmax for 4 d per week for 10 weeks.

    Other: Control training intervention

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 Apr 3, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
