Other Outcomes (1)

Study Arms (2)

Sprints during low-intensity cycling

EXPERIMENTAL

Behavioral: Inclusion of sprints during low-intensity cycling during a 14-day training camp (high training load); Behavioral: Recovery for 10 days (low training load)

Low-intensity cycling

ACTIVE COMPARATOR

Behavioral: Low-intensity cycling during a 14-day training camp (high training load); Behavioral: Recovery for 10 days (low training load)

Interventions

Inclusion of sprints during low-intensity cycling during a 14-day training camp (high training load) BEHAVIORAL

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.

Sprints during low-intensity cycling

Low-intensity cycling during a 14-day training camp (high training load) BEHAVIORAL

Low-intensity cycling

Recovery for 10 days (low training load) BEHAVIORAL

Habitual low-intensity cycling (\>0.5-2 hours per session)
