Cover Story: Dietary nitrate supplementation, provided as nitrate-rich beetroot juice, can enhance muscle contraction, particularly in fast-twitch muscle fibers. Although dietary nitrate supplementation has been evidenced to improve running and cycling, few studies have examined if nitrate ingestion can improve resistance exercise, which relies on the recruitment of fast-twitch muscle fibers. We found that acute nitrate ingestion (i.e., ~2.5 h prior to exercise), but not 4 days of supplementing, increased the number of repetitions-to-failure during bench press. However, neither power nor speed during bench press and back squats were improved. Acute beetroot juice ingestion may increase muscular endurance during upper body resistance exercise.
