Abstract:
Introduction: For athletes, an excessive increase in blood urea nitrogen (BUN) after
multiple endurance exercises indicates muscle glycogen depletion that induces a
diminution in performance. Our study aimed to examine the efficacy of chocolate
milk (CM) compared with carbohydrate-protein replacement drink (CHOPRO) in
suppressing the increase in BUN level following multiple rowing exercises among
national male rowing athletes aged 18–23 years. Methods: Seven male athletes from
the Rowing National Training Centre, Pengalengan, West Java, participated in this
single-blind, randomised crossover study. They received CM or CHOPRO during
four hours of recovery between two endurance exercises. Before (pre) and after (post)
multiple exercises, a venous blood sample was collected to measure the increase
in BUN level. The effects of each beverage on BUN level were compared using an
independent t-test. Results: The increase in pre-post BUN level was significantly
lower for CM trial compared to CHOPRO trial (164.0±61.3 mmol/L vs 293.5±88.3
mmol/L, p=0.012). Conclusion: It was observed that CM reduced rate of increase in
BUN level following multiple rowing exercises. Thus, CM can be useful for athletes
during intense training regimen with multiple exercise sessions. Future studies
should investigate the effect of CM in various types of sports, using convenient,
non-invasive, and real-time measurement.
