Abstract Resume

Background: Water pole (WP) is a sport with intermittent characteristics, i.e. high intensity periods interspersed with brief recovery period in low to moderate intensity. In
addition, physiological exercise responses in aquatic environment are very specific, and different from running or cycling activities. This scenario shows the importance of developing specific tests
to determine the levels of aerobic and anaerobic fitness. Thus, the aim of our study was to propose a specific protocol test for WP athletes.

Methods: Twenty three athletes took part in this study. Athletes performed specific tests for WP in the aquatic environment (with an interval of 48 hours): Anaerobic test for WP
(AnaWP) - performing of 30 jumps vertically (recorded by camcorder) with specific lower limb movements of WP (known as eggbeater). Athletes’ performance was determined by evaluating the height (cm)
achieved in the 1st, 15th and 30th (H1st/15th/30th) jumps, jumps total time (TT30-seconds) and fatigue index (FI-%). Blood samples were collected for the lactate assessment immediately after the 30th
jump (0) and at 1st, 3rd, 5th, 8th and 12th minutes after test ([Lac0/1/3/5/8/12]); Aerobic test for WP (AerWP) - performing WP eggbeater in vertical position by maintaining the water at the level of
the xiphoid process. The initial ballast (held at chest level) had 2kg and was increased every 3 minutes, 2kg, until voluntary exhaustion. At the end of each stage, blood was collected for the lactate
determination and measurement of pulmonary gas exchange. Maximal oxygen uptake (VO2max), maximal HR (HRmax), maximum load (Lmax - ballast) reached and the peak concentration of lactate ([Lacp]) were
measured. The calculation of the ballast weight and HR of the second lactate threshold (LT2) was determinate by linear interpolation for lactate at 4mmol/L. The % of HRmax and Lmax in LT2 were
calculated. The data were presented by descriptive statistics.

Results: AnaWP (n=23) - H1st (44±6 cm), H15th (32±7 cm) and H30th (24±9 cm); TT30 (56.9±9.5 s); FI (42.0±12.5%); [Lac0], [Lac1], [Lac3], [Lac5], [Lac8] and [Lac12] (5.2±1.7; 7.8±1.6;
9.0±2.0; 9.4±2.2; 9.2±2.7; 8.5±2.2mmol/L, respectively); AerWP (n=23): VO2max (44.4±5.3mL/kg/min), HRmax (174.3±9.1bpm), [Lacp] (8.6±2.1mmol/L), Lmax (12.9±2.3kg) and LT2 (157.5±13.5bpm and 8.9±2.5kg,
90.5±8.2% of HRmax and 69.2±14.4% of Lmax, respectively).

Conclusions: The AnaWP and AerWP tests have potential to evaluate WP athletes and to prescribing individualized training. Finally, the obtained indexes in AnaWP were consistent with
the Wingate test and AerWP reached literature criteria in determining VO2max and LT2.
