The aim of this study is to investigate the acute effects of inspiratory muscle fatigue on lower extremity isokinetic performance. Respiratory muscles play a role not only in maintaining ventilation but also in ensuring postural stability and regulating blood flow to peripheral muscles during exercise. Therefore, it is believed that fatigue in the inspiratory muscles can affect peripheral muscle performance. In line with this investigation, 15 healthy male athletes (21.56 ±1.71 years, 179.5 ±6.04 height, 75.25 ±8.69 body mass) aged 18–25 volunteered to participate. Participants were included in three protocols: experimental, sham, and control. Measurements were performed. In the experimental condition, inspiratory muscle fatigue was induced by performing 30 sets of 2 repetitions at 60–70% of maximum inspiratory pressure (MIP). In the sham condition, the same procedure was performed without any load. In the control condition, only MIP/MEP measurements and isokinetic strength measurements were conducted. Isokinetic measurements were performed using an isokinetic dynamometer at angular velocities of 60°/s and 180°/s. Analysis of the data revealed no statistically significant changes in MIP, MEP, and isokinetic peak torque values following the inspiratory muscle fatigue protocol (p>0.05). However, a correlation analysis of the obtained strength values revealed no significant relationship between the two different strength parameters, MIP/MEP and isokinetic strength (p>0.05). In conclusion, acute inspiratory muscle fatigue does not significantly reduce lower-extremity isokinetic strength production. These findings provide important insights into the role of respiratory muscle function in athletic performance.
