The training loads must respect a standard training model that contemplates the individualization of the physical demands of the match, for each playing position, as for each individual.Įnsuring adequate levels of training and recovery to maximize player performance has continued to drive the necessity to monitor the training load and physical training output of soccer players (Owen et al., 2017) however, designing periodized training programs for team sports athletes poses unique challenges and difficulties (Mujika et al., 2018), and a common problem for coaches is determining the appropriate training loads to prescribe during the week (Clemente et al., 2019a) and the competition phase of the season (Kelly and Counts, 2007). The weekly load is characterized by a greater weighting on accelerations and decelerations, compared to distances at very-high speed and sprint. Weekly significant differences are observed between the playing positions to relative moderate-intensity accelerations ( p = 0.002), relative high-intensity accelerations ( p < 0.001), and relative moderate-intensity decelerations ( p < 0.001). On matchday-2 session, there are significant differences to relative high-speed running distance ( p = 0.025), relative very high-speed running distance ( p = 0.008), and relative moderate-intensity decelerations ( p < 0.001). On matchday-3 session, there are significant differences to relative very high-speed running distance ( p = 0.017) and relative moderate-intensity decelerations ( p = 0.014). The results show, on matchday-5 session, the existence of significant differences between playing positions to relative total distance covered ( p = 0.050), relative sprint distance ( p = 0.001), relative moderate-intensity accelerations ( p < 0.001), relative high-intensity accelerations ( p = 0.003), relative moderate-intensity decelerations ( p < 0.001), and relative high-intensity decelerations ( p = 0.017). Match-reference values were calculated as the mean of the five best values recorded during official matches. Data collected comprises 19 competitive microcycles with a standard structure composed of 3 training sessions (matchday-5, matchday-3, and matchday-2) and one match. Twenty-four amateur soccer players (22.3 ± 1.7 years) were monitored using a global positioning system. This study aims to describe and characterize the daily and weekly external load in an amateur soccer team and based on the weighting factors determined by the match reference, compare the external loads between playing positions. Ensuring adequate levels of training and recovery to maximize player performance is critical however, there are methodological challenges in designing a periodized training program for soccer teams.
