New Zealand blackcurrant extract enhances fat oxidation during prolonged cycling in endurance-trained females

Abstract: PurposeNew Zealand blackcurrant (NZBC) extract has previously been shown to increase fat oxidation during prolonged exercise, but this observation is limited to males. We examined whether NZBC intake also increases fat oxidation during prolonged exercise in females, and whether this was related to greater concentrations of circulating fatty acids.MethodsIn a randomised, crossover, double-blind design, 16 endurance-trained females (age: 28 ± 8 years, BMI: 21.3 ± 2.1 kg·m−2, VO2max: 43.7 ± 1.1 ml·kg−1·min−1) ing… Show more

“…As far as we know, only blackberry has been reported to enhance whole-body fat oxidation at rest in males, but ethnicity was not reported [ 10 ]. In Caucasian endurance-trained men and women, enhanced exercise-induced fat oxidation was observed with the intake of New Zealand blackcurrant extract [ 9 , 32 , 40 ]. Interestingly, in the study with Caucasian women [ 40 ], the exercise-induced fat oxidation was associated with increased non-esterified fatty acids concentration at rest, an indication of enhanced lipolysis.…”

Interestingly, in the study with Caucasian women [ 40 ], the exercise-induced fat oxidation was associated with increased non-esterified fatty acids concentration at rest, an indication of enhanced lipolysis. Therefore, in Southeast Asian men, New Zealand blackcurrant does not seem to affect lipolysis; fat oxidation at rest was also not affected.…”

“…In addition, all these performance studies except Willems et al (2015) used men, therefore studies in women are needed to confirm no differences between the sexes. A recent study by Strauss et al (2018) The effects of other high anthocyanin content fruits on exercise performance are less clear though. For example, cherry has received considerable interest for its effects on recovery (Bell et al, 2014;Bell et al, 2016;Bowtell et al, 2011;Connolly et al, 2006;Howatson et al, 2010), however there is limited evidence on its potential to increase exercise performance without a mechanically damaging or metabolically fatiguing protocol ( Table 1).…”

“…A clear benefit of NZBC's shortterm intake on fat oxidation and physical performance has been demonstrated, and the extract seems to benefit the repeated sprint performance only in trained players [65]. Moreover, 7 day NZBC intake augments fat oxidation during 120 min moderate-intensity exercise in endurance-trained females [66].…”
