Abstract
The application of resistance over the shoulder or hips during resisted sprints could influence performance outcomes but has not been thoroughly investigated. This study examined the within-session reliability of sprint performance measures and compared the outcomes of 1080 Sprint device between belt (hips) and harness (shoulders) attachment. Twelve student-athletes completed three 20 m sprints with resistance equivalent to 25% of body mass (14.0 to 24.7 kg). Sprint split times (5 m, 10 m, 15 m, 20 m), peak velocity, and distance at peak velocity were recorded with 1080 Sprint. Within-session reliability was assessed using intraclass correlation coefficients (ICC$_{3.1}$) and coefficients of variation (CV), while differences in performance were analysed using paired t-tests and effect sizes (ES). Reliability was excellent for all variables (ICC$_{3.1}$ ≥ 0.93; CV ≤ 3.08 %) except distance at peak velocity, which showed poor reliability (ICC$_{3.1}$ ≥ 0.32; CV ≥ 17.2 %). Sprint times and peak velocity were faster with the belt attachment (ES ≥ 0.93), while peak velocity was reached earlier with the harness attachment (ES = 0.65). Both attachment points provided reliable measurements, but the belt consistently resulted in faster 20 m sprint performance. Coaches and practitioners should consider these differences when assessing resisted sprint performance or prescribing training to ensure consistent and individualized loading strategies.

Title:Znotrajobiskovna ponovljivost in primerjava v zmogljivosti med izvedbo sprinta proti uporu z napravo 1080 Sprint med izvedbo s pasom in oprtjo
Abstract:
Namestitev enakega upora preko ramen ali bokov med sprinti proti uporu lahko vpliva na zmogljivost. Namen te študije je bil preučiti ponovljivost meritev zmogljivosti sprinta znotraj obiska in primerjati hitrost sprinta proti uporu s pritrditvijo preko pasu (na bokih) in preko oprti (na ramenih). Dvanajst študentov-športnikov je izvedlo tri sprinte proti uporu 25 % telesne mase (14,0 do 24,7 kg) na razdalji 20 m. Vmesni časi sprinta (na 5 m, 10 m, 15 m, 20 m), največja hitrost ter razdalja pri največji hitrosti so bili izmerjen iz napravo 1080 Sprint. Znotraj obiskov na zanesljivost je bila ocenjena z intraklasnim koeficientom korelacije (ICC$_{3.1}$) in koeficientom variance (CV), medtem ko so bile razlike v izvedbi analizirane s t-testi za odvisne vzorce. Ponovljivost je bila odlična za vse spremenljivke (ICC$_{3.1}$ ≥ 0.93; CV ≤ 3.08 %) razen za razdaljo pri največji hitrosti, ki je pokazala slabo ponovljivost (ICC$_{3.1}$ ≥ 0.32; CV ≥ 17.2 %). Vmesni časi in največja hitrost so bili hitrejši s pritrditvijo preko pasu (ES ≥ 0.93), medtem ko je bila največja hitrost dosežena prej s pritrditvijo preko oprti (ES = 0.65). Obe pritrdišči sta zagotavljali zanesljive meritve, vendar je pas dosledno omogočal hitrejšo izvedbo sprinta na 20 m. Trenerji in strokovnjaki naj te razlike upoštevajo pri vrednotenju zmogljivosti sprinta proti uporu ali predpisovanju vadbe, da zagotovijo konsistentne strategije obremenjevanja.
