| Resumo: | Aim: The aim of this study was to track and compare the changes of performance and energetic profile of male and female masters swimmers during a season.
Methods: Eleven female (age: 34.7±7.3-y) and fourteen male (age: 35.6±7.4-y) with 3.9±1.6-y and 4.2±3.7-y of experience in masters, respectively, performed an all-out 200 m freestyle to evaluate total energy expenditure (Etot), aerobic (Aer), anaerobic lactic (AnL) and alactic (AnAl) contributions. The oxygen uptake (VO2) was measured immediately after the 200m trial and the VO2 reached during the trial was estimated through the backward extrapolation of the O2 recovery curve. Fingertip capillary blood samples were collected before the 200 m and at the 3rd, 5th, and 7th minutes after finishing the trial.
Results: Significant differences were observed between male (TP1:177.50±30.96; TP2:174.79±29.08; TP3:171.21±22.38) and female (TP1:205.18±24.47; TP2: 197.45±20.97; TP3: 193.45±18.12) for 200 m freestyle performance at the three TPs. Male presented higher Etot in the three TPs (TP1:230.40±48.40; TP2:242.49±37.91; TP3:257.94±46.32) than female (TP1:188.51±35.13; TP2:193.18±20.98; TP3:199.77±25.94). Male presented higher AnL (TP1:33.42±6.82; TP2:30.97±8.73; TP3:30.66±8.27) and AnAl (TP1:30.6067±3.48; TP2:30.606±3.48; TP3:30.605±3.48) than female. Aerobic metabolism is the major contributor for the Etot in male (TP1:71.63±4.99; TP2:74.05±5.03; TP3:76.14±4.46) and female (TP1:76.87±3.86; TP2:79.40±3.63; TP3:78.40±5.54).
Conclusions: The better performance obtained by male compared with female may be due to different contribution of energetic pathways. Aerobic metabolism was the major contributor to Etot in a 200 m race, in both genders. Partial aerobic contribution was higher in female, while partial anaerobic contribution was greater in male. |
