Does caffeine ingestion before a short-term sprint interval training promote body fat loss?

Braz. j. med. biol. res; 52 (12), 2019
We investigated the effect of caffeine ingestion combined with a 2-wk sprint interval training (SIT) on training-induced reductions in body adiposity. Twenty physically-active men ingested either 5 mg/kg of cellulose as a placebo (PLA, n=10) or 5 mg/kg of caffeine (CAF, n=10) 60 min before each SIT sessi...
