This research was partially funded by an unrestricted grant of the Centro de Información Cerveza y Salud (CICS), Madrid, Spain. F.J.A.-G. and A.D.-l.-O are supported by a training grant from the Spanish Ministry of Education (FPU14/04172 and FPU15/03960).Résumé
High-intensity interval training (HIIT) is promoted as a time-effcient strategy to improve
body composition but concomitant beer intake, which is common among physically active individuals,
may interfere with these effects. The primary aim of this study is to determine the effects of a 10-week
(2 days/week) HIIT program on anthropometric and body composition measurements, and to assess
whether those effects are influenced by the moderate consumption of beer (at least 5 days/week),
or its alcohol equivalent. Young (24 ± 6 years old) healthy adults (n = 72, 35 females) volunteered for
a non-training group (Non-Training group) or for HIIT training. Those going for training choose
whether they preferred to receive alcohol or not. Those choosing alcohol were randomly allocated for
receiving beer (5.4%; T-Beer group) or the equivalent amount of alcohol (vodka; T-Ethanol group)
in sparkling water. Those choosing no-alcohol were randomly allocated for receiving alcohol-free
beer (0.0%; T-0.0Beer group) or sparkling water (T-Water group). From Monday through Friday,
men ingested 330 mL of the beverage with lunch and 330 mL with dinner; women ingested 330 mL
with dinner. Before and after the intervention, anthropometry and body composition, through
dual-emission X-ray absorptiometry, were measured. No changes in body mass, waist circumference,
waist/hip ratio, visceral adipose tissue or bone mineral density occurred in any of the groups.
By contrast, in all the training groups, significant decreases in fat mass together with increases in lean
mass (all p < 0.05) occurred. These positive effects were not influenced by the regular intake of beer
or alcohol. In conclusion, a moderate beer intake does not blunt the positive effect of 10-week HIIT
on body composition in young healthy adults.
