Adaptations to Speed Endurance Training in Highly Trained Soccer Players

Abstract

In highly trained soccer players, additional speed endurance training is associated with an improved ability to perform repeated high-intensity work. To what extent the training-induced changes in V˙O2 kinetics and mechanical efficiency in type I fibers caused the improvement in performance warrants further investigation.

Influence of oxygen uptake kinetics on physical performance in youth soccer

“…(10 km/h) to severe (16 km/h) transition in highly trained adult soccer players, following a period of additional 472 speed endurance training. This was despite significant improvements in Yo-Yo IR1 performance (11.6 ± 6.4%) 473 and pulmonary VO 2 kinetics during an unloaded to moderate transition (11.4 ± 16.5%) (Nyberg et al, 2016). 474…”

Combined speed endurance and endurance exercise amplify the exercise‐induced PGC‐1α and PDK4 mRNA response in trained human muscle

“…; Nyberg et al. ), but no study has investigated the acute response of combining speed endurance exercise with endurance exercise within the same session.…”

“…Performing speed endurance training (all-out intermittent 30 sec of exercise at an average of~90-95% of maximal intensity) and a basic volume of endurance training for 2-9 weeks has been found to improve short-and long-term performance in runners Iaia et al 2009), cyclists Gunnarsson et al 2013), and soccer players (Thomassen et al 2010;Christensen et al 2011;Gunnarsson et al 2012;Nyberg et al 2016), but no study has investigated the acute response of combining speed endurance exercise with endurance exercise within the same session.…”
