## 4 Discussion
Lastly, no physiological or perceptual measures--such as blood lactate concentration, muscle oxygenation (e.g., via near-infrared spectroscopy), or rating of perceived exertion (RPE)--were included in the protocol. While previous studies have shown that BFR induces greater lactate accumulation and muscle swelling during dynamic tasks compared to sustained isometric contractions, the present investigation prioritized mechanical output variables. Integrating such physiological and perceptual metrics in future studies would contribute to a more comprehensive understanding of acute fatigue and recovery responses under BFR, particularly in female populations. In summary, acute BFR application did not significantly alter RFD kinetics during isometric mid-high pull assessments in young women. These findings suggest that under the tested conditions, BFR does not impair explosive isometric performance. These challenge assumptions were drawn from dynamic protocols and highlight the importance of task-specific evaluation. From an applied perspective, BFR may be a viable strategy for maintaining neuromuscular function under low-load conditions, although future studies should examine its chronic effects and adaptability to other tasks and populations.
