Table 2

Physiological responses at moderate and severe intensities after the nutritional intervention with the BET and PLA gel supplementations.

Men and women	Group	Warm up	Moderate	Peak (severe)
RQ	PLA				<0.0001
	BET				<0.0001
HR (bpm)	PLA				<0.0001
	BET				<0.0001
RPE (Borg)	PLA				<0.0001
	BET				<0.0001

Values are presented as mean ± SD. BET, beetroot gel ( mmol⋅100 g⁻¹); PLA, placebo gel ( mmol⋅100 g⁻¹); RQ, respiratory quotient; HR, heart rate; RPE, rating of perceived exertion.
