  "abstract": "Background\n\nParachute-resisted sprint training (PRST) is a practical field-based resisted-sprint method that uses aerodynamic drag to provide sprint-specific overload. Although PRST has been widely used in athletic settings, evidence on its acute mechanical effects and chronic training adaptations remains heterogeneous.Objectives\n\nThis systematic review aimed to synthesize the acute and chronic effects of PRST on sprint performance, sprint mechanics, neuromuscular responses, and sprint-related physiological outcomes in healthy, physically active, and athletic populations.Methods\n\nA systematic search was conducted in PubMed, Scopus, Web of Science, and SPORTDiscus on 17th May 2026. Original empirical studies were eligible if they examined PRST or parachute-resisted sprinting and reported outcomes related to sprint performance, biomechanics, neuromuscular responses, or sprint-related physiology. Studies were synthesized narratively and grouped into acute and chronic evidence streams. Methodological quality was assessed using the Modified Downs and Black checklist, and certainty of evidence was rated using the GRADE approach.Results\n\nSeventeen studies were included (8 acute and 9 chronic). In acute comparisons, PRST consistently reduced sprint velocity or increased sprint time; where directly reported, velocity reductions were approximately 3.4-6% relative to unresisted sprinting. Larger parachute conditions generally produced greater velocity decrements and changes in horizontal force or impulse variables. Chronic studies reported improvements in selected sprint outcomes, including 0-10 m, 10-20 m, and 0-20 m splits in one randomized study; other studies reported improvements such as 3.48% in 60-yd performance and 0.618 s in 100-m performance. However, chronic studies' findings were heterogeneous, and evidence for maximal velocity, neuromuscular or energetic outcomes, and population-specific effects remained limited.Conclusions\n\nPRST appears to provide a practical, sprint-specific overload and may improve selected sprint performance outcomes. However, the current evidence base is limited by small sample sizes, heterogeneous protocols, poor quantification of resistance, inconsistent reporting of outcomes, and limited comparator control. Based on GRADE, confidence in the evidence is generally 'low' to 'very low' across most outcomes. Trial Registration (OSF) https://osf.io/56nct DOI: 10.17605/OSF.IO/8SJW4.",
