What it does not prove
- The study design is cohort without a control group; no comparison group receiving usual care or alternative intervention is reported, so causality and the magnitude of exercise-specific effects cannot be determined.
- Results of the analysis are not reported in the provided material—only study design and planned measurements are described—so what changes actually occurred in biological age or other outcomes remains unknown.
- Whether observed associations, if any, reflect genuine slowing of aging processes versus measurement noise or regression to the mean cannot be determined from the information provided.
Extracted from supplied source material; model confidence is not a measured probability of correctness.

Abstract or registry material supplied for assessment; source version 2. This is not a claim of full-text review.
This study investigated the effects of a structured 6-month high-intensity interval training (HIIT) program on blood DNA methylation-based measures of biological ageing, physical fitness, cardiovascular function, body composition, metabolic health, and the gut microbiome in adults aged 50-70 years.
Participants completed supervised exercise training three times per week for 6 months.
High-intensity intervals were performed above approximately 80% of estimated HRmax and were separated by 2-minute periods of active recovery.
The primary overall objective of the study was to determine whether the individual volume of exercise performed, quantified as MET-hours, was associated with changes in blood DNA methylation-based biological age acceleration following the 6-month intervention.
