Why the study?

Does 7 days intake of blackcurrant powder improve physiological and cardiovascular responses in trained triathletes?

Population

13 trained triathletes with >3 yrs experience (8 men, age: 38 ± 8 yrs, body mass: 71 ± 9 kg, BF%: 19 ± 5%)

Comparison

Sujon New Zealand blackcurrant powder for 7 days vs Placebo (cross-over design with 4 weeks wash-out)

Design

RCT, randomized and cross-over, double-blind, placebo-controlled

Follow-up

7 days

Overview

May support blackcurrant use to lower lactate in trained athletes; extends hemodynamic data to exercise settings.

Structured PICO

P
Population
13 trained triathletes with >3 yrs experience (8 men, age: 38 ± 8 yrs, body mass: 71 ± 9 kg, BF%: 19 ± 5%)
I
Intervention
Sujon New Zealand blackcurrant powder (6g/day) for 7 days
C
Comparator
Placebo (cross-over design with 4 weeks wash-out)
O
Outcome
Lactate curve, maximum oxygen uptake, and cardiovascular responses at rest and during cyclingsurrogate

Short-term blackcurrant intake alters lactate responses during exercise and improves resting cardiovascular hemodynamics in trained triathletes.
