Energy cost and energy sources of a ballet dance exercise in female adolescents with different technical ability.
This study evaluated energy cost and energy sources of a ballet exercise (grand adage) in young female dancers with different technical ability, and then related the energy sources to the subject's VO(2max) and anaerobic threshold (IAT). Twenty-five dancers (13-16 years) were divided into two different technical ability groups: low-level (n = 13) and high-level (n = 12). The overall energy requirement of dance exercise (VO(2eq)) was obtained by adding the amount of VO(2) during exercise above resting (aerobic source or VO(2ex)) to the VO(2) up to the fast component of recovery (anaerobic alactic source or VO(2al)) and to the energy equivalent of peak blood lactate accumulation (anaerobic lactic source or VO(2la) of recovery. VO(2eq) of exercise amounted to 81 +/- 10 and 94 +/- 9 ml kg(-1) in low-level and high-level groups, respectively. VO(2ex) represented the higher fraction (65 +/- 4% and 77 +/- 5%) in low-level and high-level groups, respectively, of VO(2eq )in both the groups. In the low-level group the remaining fractions were: 23 +/- 2 % for VO(2al) and 12 +/- 1% for VO(2la). In high-level group the remaining fractions were: 18 +/- 2 % for VO(2al) and 4 +/- 1% for VO(2la). Between two groups, significant differences were found in VO(2ex )(P
