Abstract
Force–velocity profiling (FVP) provides a practical assessment of neuromuscular capabilities, yet its application to rowing performance remains underexplored. This study investigated the relationship between squat jump–derived FVP metrics and 250 m split performance during a 2 km rowing ergometer test in male varsity rowers. Sixteen athletes (age = 21.12 ± 1.68 y; height = 1.88 ± 0.07 m; body mass = 86.58 ± 9.47 kg) completed a 2 km ergometer trial followed by loaded squat jumps to determine maximal force (F₀), maximal velocity (V₀), maximal power (Pₘₐₓ), and the slope of the force–velocity
relationship (SFV). Linear regression analyses revealed that SFV significantly predicted power output across all race segments (r = −0.54 to −0.82), while F₀ significantly predicted all but the first segment (r = 0.51–0.83). Pₘₐₓ and V₀ showed no significant relationships with any segments. Across the race profile, the predictive strength of F₀ increased in later stages, suggesting that force production becomes more critical as fatigue accumulates. These findings highlight the utility of FVP, particularly F₀ and SFV, for monitoring mechanical capabilities relevant to sustained rowing performance and for informing strength-oriented training interventions.
