Summary

To investigate the effects of Including 30-s sprints during low-intensity cycling exercises during a training camp on performance and muscle/blood characterisitcs in elite cyclists

Detailed description

Inclusion of sprint intervals during low-intensity training (LIT) sessions has been suggested as a potential mean to improve endurance performance in elite cyclists, facilitated by muscular or systemic physiological adaptations. So far, the effects of such training has been studied exclusively in context of short-lasting low-intensity sessions, representing a scenario with suboptimal ecological validity for such highly trained athetes. This study will investigate the effects of including sprints during prolonged LIT-sessions sessions during a 14-day training camp focusing on LIT, followed by 10 days recovery (REC), on performance and performance-related measures in elite cyclists. During the training camp, a sprint training group will conduct 12x30-s maximal sprints during five LIT sessions, whereas a control group will perform distance-matched LIT-only. Overall, the training camp will lead to substantial increases in training load compared to habitual training in both intervention groups, followed by subsequent reductions during REC. Performance tests will be conducted before the training camp (T0) and after REC (T2). Muscle biopsies, hematological measures and stress/recovery questionnaires will be collected Pre (T0) and after the camp (T1). The study was pre-registered at Norwegian Center for Research Data (14/08/2017, Norwegian): http://pvo.nsd.no/prosjekt/55322

Interventions

Type	Name	Description
BEHAVIORAL	Inclusion of sprints during low-intensity cycling during a 14-day training camp (high training load)	Inclusion of 12x30-s maximal sprints during five low-intensity cycling sessions with long duration (\>fours hours per session). Five sessions will be performed as low-intensity cycling-only (Controll sessions, distance matched). All other sessions will be performed as low-intensity sessions and adjusted according to each participants training load goal to reach an increase of \~50% in load compared to habitual training.
BEHAVIORAL	Low-intensity cycling during a 14-day training camp (high training load)	Five low-intensity cycling sessions (\>four hours per session), distance-matched to sprint group.
BEHAVIORAL	Recovery for 10 days (low training load)	Habitual low-intensity cycling (\>0.5-2 hours per session)
