Bottom Line: Then, these data were compared according to the opponent team level (first league; second league; amateurs).Time-motion demands showed no differences in total distance covered per opposition levels, while matches opposing teams of superior level revealed more distance covered at very high intensity.Competing against superior level teams implied more time in synchronized behavior for the overall displacements and displacements at higher intensities.

ABSTRACT
This study aimed to quantify the time-motion demands and intra-team movement synchronization during the pre-season matches of a professional soccer team according to the opposition level. Positional data from 20 players were captured during the first half of six pre-season matches of a Portuguese first league team. Time-motion demands were measured by the total distance covered and distance covered at different speed categories. Intra-team coordination was measured by calculating the relative phase of all pairs of outfield players. Afterwards, the percentage of time spent in the -30° to 30° bin (near-in-phase mode of coordination) was calculated for each dyad as a measure of space-time movement synchronization. Movement synchronization data were analyzed for the whole team, according to each dyad average speed and by groups of similar dyadic synchronization tendencies. Then, these data were compared according to the opponent team level (first league; second league; amateurs). Time-motion demands showed no differences in total distance covered per opposition levels, while matches opposing teams of superior level revealed more distance covered at very high intensity. Competing against superior level teams implied more time in synchronized behavior for the overall displacements and displacements at higher intensities. These findings suggest that playing against higher-level opponents (1st league teams) increased time-motion demands at high intensities in tandem with intra-team movement synchronization tendencies.

Mentions: Time-motion variables showed no differences in the total distance covered between opposition levels (F(2, 57) = 2.247, p = 0.115, η2 = 0.073) (Table 1). An increase in the distance covered at moderate intensity running was observed in matches against amateur players (F(2, 57) = 3.425, p = 0.039, η2 = 0.107). On the other hand, an increase in the distance covered at very high intensity running was also found in matches opposing first league teams (F(2, 57) = 3.296, p = 0.044, η2 = 0.104). Pairwise effect size analyses revealed no clear tendency in time-motion variables between opposition levels (Figure 2).
