The aim of the present investigation was to analyse the association between physical fitness profiles, playing positions and the profile relationships between training output amongst elite professional soccer players.
20 professional players (height: 182.0 ± 3.2 cm, body mass:77.4 ± 6.1 kg, 25.7 ± 3.4 years) competing at UEFA Champions League level were involved in the present investigation.
Players assessments included speed (5m and 20m), agility (T-test), jump performance (SJ and CMJ) and aerobic power (VO2max) at the start of pre-season.
Players training outputs were recorded with global positioning systems (Statsports, Viper Pod, Newry, Northern Ireland) across 5 micro-cycles at the start of competitive period.
Total distance (TDC; m), relative distance (m.min-1), high-speed running (HSR; m), explosive distance (m), total accelerations (n), total decelerations (n) and total sprints (n) were measured.
No difference between playing positions was found in the physical tests.
Jump and 20m-speed tests were significantly correlated with total accelerations (r= 95% CI:), total decelerations (r = 95% CI:), total sprints (r = 95% CI:), HSR (m) (r= 95% CI:) and HSR (m.min-1) (r= 95% CI:). 5m-speed test significantly correlated with explosive distance (r= 95% CI:). VO2max correlated with all metrics (p
< 0.05) except total decelerations (r= 95% CI:) and TDC (r= 95% CI:).
