Popis: | Peak torque during an isokinetic bilateral knee extension or flexion is usually lower than the summed peak torque of two unilateral contractions, and this phenomenon is designated as bilateral deficit (BD). The objectives of this study were to determine whether a BD also exists for more complex, alternating movements (e.g., short-term, high-intensity cycling), and to assess the possible effects of gender and maturity. Forty children and adolescents performed two unilateral (ULWAnT) and one bilateral Wingate anaerobic test (BLWAnT). The highest power reached in any 3-s interval (peak power; PP), and the total mechanical work (TMW) performed during the test was determined. Individual BD for PP (BDpp, %) was calculated by dividing the PP in the BLWAnT by the sum of the PP values of both ULWAnTs. The BD for TMW (BDTMw) was calculated in the same way. The sum of PP generated during the two ULWAnTs was larger than the PP measured in the BLWAnT (P |
