OBJECTIVES: This study aimed to examine the effects of inspiratory muscle training (IMT) on respiratory function and Para Fencing (PF) performance, and to investigate the relationship between a PF-specific wheelchair protocol and arm-crank ergometer performance.
DESIGN: A pre-post intervention case series.
SETTING: Laboratory-based assessments.
PARTICIPANTS: Five Para Fencing athletes with spinal cord injury (T1-L1), classified as classes A and B.
MAIN OUTCOME MEASURES: Pulmonary function, maximal inspiratory (PImax) and expiratory pressures (PEmax), cardiopulmonary exercise testing using an arm-crank ergometer, blood lactate peak, and performance in a PF-specific wheelchair protocol.
RESULTS: Following six weeks of IMT, PImax and PEmax increased by 10.9% and 15.5%, respectively, indicating improved respiratory muscle strength. Blood lactate peak showed a large effect size (0.87) after training. A strong correlation was observed between the duration of the PF-specific protocol and peak oxygen uptake obtained from the arm-crank ergometer test (r = 0.90; p = 0.037).
CONCLUSIONS: Aerobic capacity appears to be strongly associated with PF performance. Although IMT significantly improved respiratory muscle function, its direct impact on sport-specific performance remains inconclusive in this sample.
