[en] Aim: The aim of this study was to analyse the physical effects of a soccer half-season in female soccer players. Methodology: Sixteen elite soccer players, from the female second league "Reto Iberdrola Norte", participated. Trained and played minutes were registered during 21 training weeks, of which 6 were part of the preseason and 15 of the seasons. Totally 63.5 ± 29.5 training were performed, 34 trainings the less trained player and 94 the most trained player; 20 matches were played, in preseason 6 and 14 official matches during the season. For these, some test was performed in the preseason (T1), endurance test in Christmas break (T2Endurance) and on February strength test (T2Strength). Thus, these tests can be divided in two groups: a) lower limb power, jump and hop test as Vertical Unilateral Drop Jump (VUDJ), Vertical Unilateral CounterMovement Jump (VUCMJ) and Cross-over Hop Test (CHT); b) endurance test, Buchheit´s 30-15 Intermittent Fitness Test (30-15IFT). Also, trained and played minutes were registered from the first training in the preseason to the last one before Christmas break, that were related with T2Endurance analysing the effect of the minutes in the aerobic capacity. So, in this work are two different studies: a) to analyse the relationships between T1 and T2Strength and b) to analyse the relationships between trained and played minutes with T1 and T2Endurance. Results: Focusing on results, dominant DJ 1 (DJ Dom 1) and no dominant DJ 1(DJ No Dom1) (r=,922; n=8; SEE=,818); DJ Dom 2 and DJ No Dom 2 (r=,939; n=8; SEE=,914) were data obtained. Observing the percentual change (Δ %) between DJ tests (r=,934; n=8; SEE=1,017), CMJ (r=,728; n=8; SEE=9,782) also CHT (r=,898; n=7; SEE=5,155). Should me added, between Δ % CHT Dom y Δ % CMJ Dom was a significant correlation (r=,811; n=6; SEE=2,942). Among CMJ Dom 1; and maximal speed obtained (VIFT) in endurance test, VIFT 1 a relation was founded (r= ,836; n=5; SEE=1,32). CMJ Dom 1 and the mean of minutes trained and played (Prom Mins M/T) was correlated (r=,656; n=6; SEE=1,81). Also, a relation was founded between endurance tests (r=,646; n=15; SEE=,933). In relation to aerobic capacity, we founded relation between played minutes with maximal speed achieved (VIFT) on the 30-15IFT. On average, those players who played more (Prom Mins M), their endurance was improved, with a correlation between Δ VIFT and Prom Mins M (r=,503; n=13; SEE=10,657). A relation among VIFT 1 and Δ % VIFT (r= ,573; n=13; SEE=,88). To conclude with results, we founded a correlation between VIFT 2 and Prom Mins M (r= ,485; n=13; SEE=,887). Conclusions: Knee extensor strength was maintained or decline during the first half of the season because of fatigue, training specificity scarcity. The trained and played minutes had positive effects on aerobic ability. The importance of aerobic ability on soccer players underline the relation between VIFT and played minutes. For maintaining or improve strength values during the season and as effect of played minutes those players who do not improve their aerobic ability, putting into their training planification some dose of non-specific work is recommended. Even so, as optimal volume as intensity of these work is pending investigate in female soccer players.

[eu] Helburua: Gradu Amaierako Lan honen helburua, denboraldi erdi batek emakumezko futbol jokalariengan duen eragin fisikoa aztertzea zen. Metodologia: Hamasei elitezko emakume futbol jokalari, bigarren mailan "Reto Iberdrola Norte" ligan jokatzen zutenak parte hartu zuten. Horretarako aurredenboraldian egindako testak (T1), gabonetako geldialdian eginiko erresistentzia testa (T2Erresistentzia) eta otsailean eginiko indar adierazleen testak (T2Indarra) kontuan hartu ziren. Aipatutako moduan, testak bi multzotan banatu genituen: a) behe gorputz ataleko potentzia adierazle testak, jauzi testak zirenak, Vertical Unilateral Drop Jump (VUDJ), Vertical Unilateral CounterMovement Jump (VUCMJ) eta Cross-over Hop Test (CHT); b) erresistentzia testa, Buchheit-en 30-15IFT-a egin zen. Entrenamendu zein jokatutako partiduen minutuak 21 astez erregistratu ziren, aurredenboraldiko 6 aste eta 15 aste denboraldian zehar. Guztira, 63.5 ± 29.5 entrenamendu burutu zituzten, gutxienak 34 eta gehienak 93, eta 20 partidu burutu zituzten, aurredenboraldi garaian, lagun arteko 6 eta 14 partidu ofizial. Horretaz gain, aurredenboralditik gabonetako geldialdiraino entrenatutako zein jokatutako minutu kopurua kontuan hartu zen, ondoren minutu horiek T2Erresistentzian izango zituzkeen eraginak aztertu genituen. Beraz, lan honen barne bi ikerketa daude: a) T1 eta T2Indarra-ren emaitzak aztertzea, eta b) Entrenatutako eta jokatutako minutu kopuruak eta T1 eta T2Erresistentzia dituzten eraginak aztertzea. Emaitzak: Emaitzei erreparatuz; DJ dominantea (Dom) 1 eta DJ ez dominantea (No Dom) 1-en (r=,922; n=8; SEE=,818); eta DJ Dom 2 eta DJ No Dom 2 (r=,939; n=8; SEE=,914) izanik. Testen arteko aldaketen ehunekoak (Δ %) ikusiz, DJ (r=,934; n=8; SEE=1,017), CMJ (r=,728; n=8; SEE=9,782) edota CHT (r=,898; n=7; SEE=5,155). Gehitu beharra dago, Δ % CHT Dom eta Δ % CMJ Dom artean korrelazio bat dago (r=,811; n=6; SEE=2,942). CMJ Dom 1; eta erresistentzia testean lortutako abiadura maximoa (VIFT), VIFT 1aren arteko harreman bat zegoen (r= ,836; n=5; SEE=1,32). CMJ 1 eta entrenaturiko zein jokatutako bataz besteko minutuen (Prom Mins M/T) artean harremana ikusi genuen (r=,656; n=6; SEE=1,81). Azkenik, erresistentzia alorrean zentratuz, entrenaturiko edota jokatutako minutuen eta VIFT aztertu genituen. 30-15IFT testetan, hobekuntza bat egon zen, bi testen artean korrelazio esanguratsu bat egonik (r=,646; n=15; SEE=,933). Bataz bestez jokatutako partidu minutuak (Prom Mins M) gero eta gehiago jokatu zutenek, beraien Δ VIFT gehiago hobetu zuten; harreman txiki bat zegoelako Δ VIFT eta Prom Mins M-aren artean (r=,503; n=13; SEE=10,657). VIFT 1 eta Δ % VIFT artean harremana zegoen (r= ,573; n=13; SEE=,88). Emaitzekin bukatzeko, VIFT 2 eta Prom mins M-en artean erlazioa zegoen (r= ,485; n=13; SEE=,887). Konklusioak: Belaun estentsiogileen indarra mantendu edo okertzen da denboraldiak sortzen duen nekea, indar indibidualizatu gutxi egiteagatik. Entrenatutako eta jokatutako minutuak eragin positiboa izan zuten jokalarien gaitasun aerobikoan. Gaitasun aerobikoaren garrantzia emakumezko futbolean VIFT vs jokatutako minutuen arteko harremanak azpimarratzen ditu. Indarra denboraldian hobetzeko edo ez galtzeko, eta gaitasun aerobikoa entrenamendu gehi partiduen eraginarekin hobetzen ez dutenentzat, lan inespezifiko ziriak sartzea gomendagariia izango litzake. Hala ere, hauen intentsitate eta bolumen optimoa ezartzeko emakumezko futbolean ikerketa gehiago behar dira.
