This study aims to evaluate the effects of a 12-week IBRT program compared to CRT on body composition, muscle strength, speed, functional capacity, and autonomic recovery in young Chilean adults. Methods: A randomized, parallel, double-blind study was conducted with 30 participants assigned to IBRT (n = 15) or CRT (n = 15). Assessments included body mass index (BMI), waist circumference, right-hand grip strength, the running anaerobic sprint test (RAST), the 6 min walk test (6 MWT), and heart rate variability (HRV) indices: low-frequency to high-frequency ratio (LF\/HF) and root mean square of successive differences (RMSSD, a time-domain HRV metric reflecting parasympathetic activity). Statistical analyses included t-tests and ANCOVA. Results: Groups were similar in age (IBRT: 25.2 \u00b1 3.19; CRT: 23.27 \u00b1 3.69, p = 0.14) and BMI (IBRT: 21.56 \u00b1 2.22; CRT: 22.36 \u00b1 1.70 kg\/m2, p = 0.40). Both groups improved significantly in waist circumference (IBRT: \u22121.85%; CRT: \u22122.37%), grip strength (IBRT: +5.47%; CRT: +4.02%), RAST (IBRT: \u22122.67%; CRT: \u22121.04%), 6 MWT (IBRT: +4.53%; CRT: +2.17%), LF\/HF (IBRT: \u221211.43%; CRT: \u22125.11%), and RMSSD (IBRT: +5.36%; CRT: +3.81%) (all p \u2264 0.01). IBRT produced significantly greater gains in 6 MWT (B = 19.51, 95% CI: 0.79 to 38.23, p = 0.04). Conclusions: Both IBRT and CRT effectively improved body composition, muscle strength, speed, functional capacity, and autonomic recovery. However, IBRT demonstrated a superior effect on aerobic capacity.<\/jats:p>","DOI":"10.3390\/jfmk10020195","type":"journal-article","created":{"date-parts":[[2025,5,28]],"date-time":"2025-05-28T06:30:26Z","timestamp":1748413826000},"page":"195","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Effects
