Abstract
Purpose
The objective of this study was to compare blood lactate concentration (LAC), heart rate (HR), rating of perceived exertion (RPE), tryptophan (TRP), prolactin (PRL), nonesterified fatty acids (NEFA), branched-chain amino acids (BCAAs) plasma concentrations, and TRP/BCAAs ratio along interval training swimming series at 90 and 95% of the mean speed 400-m front crawl (s400).
Methods
Fourteen male swimmers performed two-interval 400-m series (40 s of passive rest) at 90% (s90) and 95% (s95) of the s400, previously determined by 400-m front crawl all test.
Results
Summarized results are: (1) TRP, BCAAs, TRP/BCAAs ratio and NEFA were similar (p > 0.05) between rest and exhaustion conditions; (2) significant increases in LAC, PRL, HR and RPE (p < 0.05) for both series (s90 and s95).
Conclusions
The findings of the present study indicate that during swimming series of interval training at 90 and 95% s400, there is maintenance of TRP, BCAA, TRP/BCAAs ratio and NEFA and increases in the RPE, PRL, LAC and HR, which can be explained by the intensities and the duration of exercise. Increased PRL can be related to central fatigue in these intensities.
