Is the decline in high-intensity running activities from 1st to 2nd half more pronounced in players with a fast muscle typology

Muscle typology is heterogeneous among national level soccer players, but positional differences remain unclear. Furthermore, fast typology (FT) individuals fatigue more than slow typology (ST) individuals in lab conditions. Therefore, we investigated if muscle typology is different between playing positions and if the decay in high-intensity activities from the first to the second half is larger in FT football players than in ST players.
