The aim of this study was to examine the relationships among swimming velocity, stroke indices, and intra-abdominal pressure (IAP) during maximal front crawl swimming. Participants were 29 highly trained female university student swimmers (mean height: 1.62±0.06m, mean weight: 56.6±6.8kg). All participants performed the Valsalva maneuver in the swimming posture to establish their maximal voluntary IAP (IAP-val). In addition, they performed maximal front crawl swimming for 20m. IAP during swimming (IAP-swim) was calculated as the difference between the minimum and maximum values using the mean of three stable front crawl stroke cycles with no breath taken. IAP-swim was normalized based on IAP-val (%maxIAP). Stroke rate (SR) and stroke length (SL) were also measured as stroke indices. Significant negative correlations were observed between SR and SL, and between IAP-val and %maxIAP (P<0.01). A significant positive correlation was observed between IAP-swim and %maxIAP (P<0.05); however, no correlations with other variables were observed. These findings suggest that IAP is not related to the maximum swimming velocity or stroke indices of individual swimmers.
