Método: fueron evaluados 38 waterpolistas adolescentes de alto rendimiento (21 hombres y 17 mujeres) pertenecientes a la federación Madrileña de Natación, con edades comprendidas entre los 13 y 17 años. In conclusion, the observational methodology allowed to verify the different effects in the throws dynamics caused by the new rules in both gender. Existe suficiente evidencia sobre modelos subjetivos de cuantificación de la carga en deportes de equipo tales como el baloncesto (Foster et al., 2001; Anderson et al., 2003; Manzi et al., 2010, Moreira et al., 2012), fútbol (Impellizzeri et al., 2004; Little y Williams, 2007; Alexiou y Coutts, 2008; Coutts et al., 2009; Casamichana et al., 2013; Scott et al., 2013; Fanchini et al., 2015), rugby (Gabbett y Domrow, 2007; Elloumi et al., 2012; (Moreira et al., 2015) y voleibol (Berna Jimenez, 2014; Rodríguez-Marroyo et al., 2014; Freitas et al., 2014). Amongst Cl subjects, RA subjects, and WP players, there was no difference in age (p = 0.33) as well as in brachial systolic pressure (p = 0.52), while there was a stepwise decrease in aortic systolic pressure (116 ± 16 mm Hg vs. 107 ± 14 mm Hg vs. 106 ± 6 mm Hg, p = 0.03). With this transition there is, the initiation of swimming and the acceleration, There are positional differences in the skills and, abilities required of field players.

There are very few restrictions on, the movement of players during the frequent time, stoppages in the actual playing time, so players are, rarely inactive at any time during each quarter of a, The specialised playing positions of water polo, are the goaltenders and the field players, who in-, clude athletes who play primarily in the centre for-, ward, centre defence or wing positions. A time density index (DI) was calculated for each athlete using SAPT and MAPT. Physiological measurements, such as, the cumulative cardiovascular and metabolic de-, mands of the identified activities during games, Data from video analyses and the reported physio-, logical measurements are combined in the follow-, ing sections to present a picture of the demands of, tions that water polo players require moderately, high levels of muscular strength and power (see, quency of the multiple activities performed by field, activities in games of water polo last for <20 sec-, onds, with intense movements and sprints averag-, mance of an activity of this intensity and brevity is, likely to be highly dependent on anaerobic meta-, ities are in fact performed in sequences, resulting, in cumulative, and hence longer duration, moder-, ate and high intensity periods of exertion which, constitute approximately two-thirds of total game, Heart rate monitoring during play has dem-, onstrated that athletes spend a similar proportion, of game time with heart rates which, during teth-, ered swimming, correspond to intensities >80% of, all of the time players were in the water, ing that the intervening, lower intensity, were of insufficient duration for recovery, ensuring a persistent, moderately high demand on, Observations of players during internationa, 85% of the time, the velocities of movement in the, horizontal plane were below that which, during, constant-velocity free swimming, elicited blood, been interpreted as reflecting a high demand from, the anaerobic alactic system, a high demand on the, aerobic system for the replenishment of creatine, phosphate and a lesser emphasis on anaerobic lac-, tic metabolism for energy provision.
