The purpose of a study by Melchiorri G, Castagna C, Sorge R, Bonifazi M.(School of Sport and Exercise Sciences, Faculty of Medicine and Surgery, University of Roma Tor Vergata, Rome) was to examine game demands during highly competitive men's water-polo games after the introduction of new Federation International Natation Association (FINA) rules.

Participants of this study were 77 outfield international level men's water-polo players (age 25.9 ± 4.5 years, height 188 ± 4.5 cm, body mass 93 ± 10.9 kg).

Game earlobe blood lactate, speed, and distance covered (semiautomatic image recognition system) were measured during 6 highly competitive matches (FINA International Tournament).

In the game, players covered 1,613 ± 150 m (n = 68). This corresponds to a mean coverage rate of 54 ± 5.8 m·min (n = 68). At speeds faster than 1.4 m·s?¹ (high-intensity swimming), players covered 44% of the total distance. A significant decrease in coverage rate was detected during the final stage of the game.

Mean blood-lactate concentration was 7.7 ± 1.0 mmol·L?¹ (range 2.2-14.3).

Center Defenders (1,816 ± 496 m) covered significantly (p < 0.05) more distance swimming compared to Field (1,676 ± 348 m) and Center-Forward (1,317 ± 281 m) players.

Mean match blood-lactate concentrations for Center Forwards, Center Defenders, and Field Players were 11.2 ± 1.0 (3-14.3), 6.7 ± 0.9 (1.4-8), and 5.3 ± 0.9 mmol·L?¹ (2.2-11.9), respectively.

This study confirmed the high-intensity nature of male elite level water polo showing remarkable role-dependent game demands.

As a result, strength and conditioning interventions should be individualized and mainly address intermittent high-intensity endurance and anaerobic fitness.
