Energy Balance of Collegiate Marching Band Members During Band Camp

PURPOSE: To determine the energy balance and activity level of collegiate marching band members during summer band camp. Subjects: The subjects (n=24; 16 females, 8 males) were a subset from the Alma College Marching Band. Subjects represented a range of instruments from the entire band. The average age and weight of participants was 19.8 yr ± 1.2 yr. and 70.0 kg ± 14.4 kg, respectively.
METHODS: Energy balance (calories consumed - calories expended) was measured on four subjects per day for six consecutive days. The daily band camp schedule was similar throughout the week, consisting of a morning and afternoon drill session each lasting 3.5 hours and an evening session lasting 2.5 hours. Each drill session combined basic marching drills and field maneuvers while playing musical instruments. Calories consumed was determined by 24-hour food record combined with digital pictures of participant meals for validation. Caloric expenditure was monitored using Actiheart-4 (CamNtech, Ltd, UK) accelerometry. The Actiheart-4 was placed on each subject before the morning band camp drill session and removed the proceeding morning. Data obtained from accelerometry was used to provide estimates of total, resting, and activity energy expenditure (TEE, REE, and AEE, respectively). Activity energy expenditure was categorized as low (<3 METS), moderate (3-6 METS), and vigorous (>6 METS) activity levels.
RESULTS: The participants average energy intake was 2199 kcals ± 567 kcals. Average TEE, REE, and AEE were 2860 kcals ± 565 kcals, 1670 kcals ± 298 kcals, and 904 kcals ± 355 kcals, respectively. The subjects demonstrated a negative average energy balance of -661 kcals ± 785 kcals. Average time spent in low, moderate, and vigorous activity levels were 22.1 hr. ± 1.2 hrs, 1.6 hr ± 1.1 hr., and.09 hr ±.08 hr, respectively.
CONCLUSIONS: Marching band members participating in summer band camp displayed an overall negative energy balance. Subjects exceeded daily physical activity recommendations spending an average of ninety-nine minutes in moderate-to-vigorous physical activity levels.
