The eff ects of a swimming-based recovery session
implemented 10 h post high intensity interval
running on subsequent run performance the
next day was investigated. Nine well trained
triathletes performed two high intensity interval
running sessions (HIIS) (8 × 3 min at 85 – 90 %
VO 2peak velocity), followed 10 h later by either a
swim recovery session (SRS) (20 × 100 m at 90 %
of 1 km time trial speed), or a passive recovery
session (PRS). Subsequently, a time to fatigue
run (TTF) was completed 24 h post-HIIS. Venous
blood samples were taken pre-HIIS and pre-TTF
to determine the levels of circulating C-Reactive
