External and Internal Load Quantification in a semi-professional male football team
In order to quantify the external and internal load in a Spanish First Division U-19 football team, a prospective observational study was carried out for a microcycle during the 2018/2019 season. For a 5 training sessions and 1 match, session rate of perceived exertion (sRPE) was recorded and, with...

| Sumario: | In order to quantify the external and internal load in a Spanish First Division U-19 football team, a prospective observational study was carried out for a microcycle during the 2018/2019 season. For a 5 training sessions and 1 match, session rate of perceived exertion (sRPE) was recorded and, with accelerometry (Polar Team Pro), were analysed studying distance, sprint, running speed, decelerations and accelerations by external load, and summated heart rate zone (SHRZ) and heart rate variability (HRV) by internal load. The independence of the variables was determined and possible relationships between variables and their causality were explored. External and internal load behave independently (F=282.05; p<.001; ES=.25). Significant relationships between external and internal measures were observed: SHRZ was related con to all external variables (Distance/min, R=.845, p=.034; Sprint; r=.928, p=.008; V4/min, r=.916, p=.01; HSR/min, r=.909, p=.012; Total DF/min, r=.872, p=.023; Total AF/min, r=.921, p=.009). RRMean, con Sprint, r=-.856, p=.03; Total DF/min, r=-.943, p=.017; Total AF/min, r=-.943, p=.017). Possible causality was determined between external and internal load (R2=1.000; p=.005) and between internal load and sRPE (R2=1.000; p=.008). CE variables present a possible co-occurrence with CI variable SHRZ. The subjective IQ variable sRPE presents a possible co-occurrence with the IQ objective variables relative to HRV (RR mean, SDNN, RMSSD) and session exposure time. The training sessions, in a semi-professional context of a soccer team, do not replicate the demands of competition, this being the highest requirement of the microcycle. |
