Background. To ­assess the aero­bic and anaer­o­bic char­ac­ter­is­tics of Saudi ­elite soc­cer ­players, and to exam­ine the inter­re­la­tion­ship ­between meas­ures of aero­bic and anaer­o­bic pow­er in the ­elite soc­cer ­players.
Methods. Participant: twen­ty-­three out­field ­elite soc­cer ­players rep­re­sent­ing the Saudi nation­al ­team par­tic­i­pat­ed. Their ­means (±SD) for age, ­body ­mass, ­height and esti­mat­ed fat % ­were: 25.2±2.3 ­years; 73.1±6.8 kg; 177.2±5.9 cm; and 12.3±2.7%, respec­tive­ly. Measures: car­di­o­res­pir­a­to­ry param­e­ters, includ­ing max­i­mal oxy­gen ­uptake (V˙O2 max), ­were ­assessed by ­open-cir­cuit spi­rom­e­try dur­ing grad­ed tread­mill run­ning. Anaerobic pow­er meas­ures ­were ­obtained ­using Wingate anaer­o­bic ­test, and includ­ed ­peak pow­er (PP), and aver­age pow­er for 5 sec (AP 5), 10 sec (AP 10), 20 sec (AP 20) and 30 sec (AP 30).
Results. Mean (±SD) val­ues for V˙O2max in abso­lute and rel­a­tive to ­body ­mass ­were 4.16±0.34 l·min-1 and 56.8±4.8 ml·kg-1·min-1, respec­tive­ly. Such V˙O2max val­ue was 118% and 80% of ­those report­ed for Saudi col­lege ­males and dis­tance run­ners, respec­tive­ly. The ven­til­a­to­ry anaer­o­bic theres­hold (Tvent) aver­aged 43.6 ml·kg-1·min-1. There ­were no sig­nif­i­cant dif­fer­enc­es in V˙O2max and Tvent ­between ­players ­based on posi­tions, ­although the mid­field­ers and the cen­tre-­backs had the high­est and the low­est indi­vid­u­al val­ues for ­both meas­ures, respec­tive­ly. Values (±SD) of PP and AP 30 ­were 873.6±141.8 W (11.88±1.3 W·kg-1), and 587.7±55.4 W (8.02±0.53 W·kg-1), respec­tive­ly. Only in abso­lute PP & AP 30 ­were the cen­tre-­backs sig­nif­i­cant­ly super­i­or to the oth­er ­players. In addi­tion, V˙O2max was inverse­ly relat­ed to PP (r=-0.54; p<0.05) and pos­i­tive­ly relat­ed to AP 30 (r=0.45 ; p<0.05).
Conclusions. The aero­bic pow­er, ­expressed rel­a­tive to ­body ­mass, of Saudi ­elite soc­cer ­players was in the low­er ­range of val­ues nor­mal­ly report­ed in the lit­er­a­tures for ­elite soc­cer ­players. Both PP and AP 30 ­were some­what low­er ­than val­ues pre­vi­ous­ly report­ed for ­elite soc­cer ­players ­from oth­er coun­tries.
