ROJAS-VALVERDE, Daniel et al. Sex-related external and internal load indicators during a congested youth handball tournament in Costa Rica. Pensar en Movimiento [online]. 2024, vol.22, n.1, pp.80-99. ISSN 1659-4436.  http://dx.doi.org/10.15517/pensarmov.v22i1.53767.

The purpose of this research was to identify external and internal load indicators in youth handball, during a congested tournament held in Costa Rica, and to determine whether there are sex-related differences. Variables were selected through the Principal Components Analysis (PCA) as a data reduction technique. The data were obtained from 73 youth handball players (33 women and 38 men) from eight local clubs, during a three-day congested tournament. Twelve games were analyzed (six male and six female games) using PCA and an independent t-Student test for sex-related differences. Six major load indicators were identified-six for external load (relative distance (RD), relative acceleration (RAcc), maximum acceleration (MaxAcc), maximum speed (MS) and difference between acceleration a deceleration (DfAcc-Dec)) and one for internal load (average heart rate (AvHR)). In the men, the most representative indicators were RD, AvHR and MaxAcc, which accounted for 39.6% of the variance. In the women, these were MS and MaxAcc, accounting for 44.4% of the variance. RAcc (p < .01), MaxAcc (p < .01) and MS (p < .01) were higher in men, whereas AvHR (p = .02) was higher in women. The conclusion is that external and internal load showed differences between male and female players. Men can be characterized by volume-related variables, whereas intensity-related indicators were more frequent for women. For congested tournaments, it is important to separate training loads according to sex, as well as to prioritize the physical qualities for training.
