Summary

Cross-sectional studies clearly demonstrate that the maximal fat oxidation (MFO, onwards referred to as peak fat oxidation, PFO) and the intensity at which it occurs (Fatmax) are higher in trained compared with untrained men and women (Maunder et al. 2018; Nordby et al. 2006; Lima-Silva et al. 2010). Furthermore, a recent study in endurance-trained males have shown a relationship between PFO and performance in an Ironman triathlon (Frandsen et al. 2017). The interest of PFO and Fatmax in endurance sports is centered on the speculation that increased fat oxidation rates during exercise would benefit endurance performance (\> 4 hours) due to a glycogen sparing effect. Furthermore, it is speculated that the high amount of low-intensity training (70-80%), as seen with elite endurance athletes, might be essential in order to increase the fat oxidation capacity. However, when PFO is compared across an athletic population, football players have similar values as endurance-trained athletes (Randell et al. 2016; Randell et al. 2019; Frandsen et al. 2017), which is somewhat surprising when the different training regimes are considered.

It is noteworthy that the variations in PFO in various types of athletes and football players are considerable (Randell et al. 2016). However, different playing position in football has different work requirements, thus it might be that some of the variation seen in PFO could be related to the different playing position.

To our knowledge, no study has previously looked at the variations in fat oxidation capacity before and after a training period in athletes. Therefore, the aim of the present study is to investigate changes in peak fat oxidation and aerobic fitness during a pre-season training period in sub-elite football players. A secondary aim is to investigate if the changes are related to specific playing positions on the field. The overall hypothesis is that a pre-season training period would increase the fat oxidation capacity and aerobic fitness, and that the changes are related to specific player positions.
