Study Arms (2)

Post-Exercise Hot Water Immersion

EXPERIMENTAL

Participants will cycle for 60 minutes at 50% of maximal oxygen uptake (VO2 max) followed by 30 minutes post-exercise hot water immersion (40oC) for 5 consecutive days.

Other: Post-Exercise Hot Water Immersion

Control group

ACTIVE COMPARATOR

Participants will cycle for 60 minutes at 50% of maximal oxygen uptake (VO2 max); however, there will be not water immersion following exercise.

Other: Control Group

Interventions

Post-Exercise Hot Water Immersion OTHER

Participants will cycle for 60 minutes at 50% of maximal oxygen uptake (VO2 max) followed by 30 minutes post-exercise hot water immersion (40oC) for 5 consecutive days.

Post-Exercise Hot Water Immersion

Control Group OTHER

Participants will cycle for 60 minutes at 50% maximal oxygen uptake (VO2 max) for 5 consecutive days. There is no water immersion following the exercise.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: NONE
• Masking Details: Considering that the hot water immersion protocol will be easily perceptible to the participants, it will not be possible to blind them from their group assignment. Also, the investigators will be required to set the water temperature for the immersion protocol following each exercise session, so they will also be aware of group assignments during the intervention.
