Comparing immediate effects of intense cycling, running, and functional strength workouts
Official title: Evaluation of the Acute Effects of High-intensity Interval Aerobic Training, Moderate- and High-intensity Functional Training, and Moderate-intensity Functional Training
Run by European University Miguel de Cervantes · NCT07180550 · Data updated 2026-11-12
This trial tests how different short, intense workouts—cycling, running, high- and moderate-intensity functional training, and traditional strength sessions—affect heart, breathing, and muscle responses in healthy, active adults.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are healthy adults aged 18 or older who are classified as active on the IPAQ and have at least six months of strength training experience at intensities above 75% of one-repetition maximum.
✕Probably not a fit
People with recent musculoskeletal injury (within 6 months), recent major surgery (within 3 months), medical conditions that contraindicate exercise, or who are not regularly physically active are unlikely to benefit or be eligible.

What this trial studies
The study compares immediate cardiovascular, metabolic, and neuromuscular responses to several exercise modalities: HIIT on a cycle and treadmill, high- and moderate-intensity functional training (HIFT and MIFT), and traditional strength training. Healthy adults who are physically active and have at least six months of heavy strength training experience perform controlled exercise bouts while investigators record oxygen consumption (VO2), heart rate variability, heart rate, and metabolic markers. Each participant completes the different protocols in laboratory visits at the university with standardized warm-ups, rest periods, and data collection during and after exercise to capture acute responses. Results are intended to clarify how time-efficient high-intensity functional and interval formats compare to traditional approaches and to inform exercise recommendations for special populations.
Why it matters
Potential benefit: If successful, the findings could identify time-efficient workout formats that produce strong cardiovascular and metabolic responses and help guide safer, targeted exercise prescriptions.
How similar studies have gone: Prior research shows traditional HIIT (running or cycling) reliably provokes strong cardiovascular and metabolic responses, while high-intensity functional training is newer and less thoroughly studied for acute physiological outcomes.
