Resumen: Abstract: There is current scientific interest in naturally sourced phenolic compounds and their
potential benefits to health, as well as the effective role polyphenols may provide in an exercise setting.
This study investigated the chronic effects of supplementation with a biodynamic and organic olive
fruit water phytocomplex (OliPhenolia® [OliP]), rich in hydroxytyrosol (HT), on submaximal and
exhaustive exercise performance and respiratory markers of recovery. Twenty-nine recreationally
active participants (42 ± 2 yrs; 71.1 ± 2.1 kg; 1.76 ± 0.02 m) consumed 2 × 28 mL·d
−1 of OliP or
a taste- and appearance-matched placebo (PL) over 16 consecutive days. Participants completed a
demanding, aerobic exercise protocol at ~75% maximal oxygen uptake (
.
VO2max) for 65 min 24 h
before sub- and maximal performance exercise tests prior to and following the 16-day consumption
period. OliP reduced the time constant (τ) (p = 0.005) at the onset of exercise, running economy
(p = 0.015) at lactate threshold 1 (LT1), as well as the rating of perceived exertion (p = 0.003) at lactate
turnpoint (LT2). Additionally, OliP led to modest improvements in acute recovery based upon a
shorter time to achieve 50% of the end of exercise
.
VO2 value (p = 0.02). Whilst OliP increased time to
exhaustion (+4.1 ± 1.8%), this was not significantly different to PL (p > 0.05). Phenolic compounds
present in OliP, including HT and related metabolites, may provide benefits for aerobic exercise
and acute recovery in recreationally active individuals. Further research is needed to determine
whether dose-response or adjunct use of OliP alongside longer-term training programs can further
modulate exercise-associated adaptations in recreationally active individuals, or indeed support
athletic performance.
