Introduction Effects on strength performance and muscle activation in the contralateral limb have been observed after training with the ipsilateral limb (IL). Cross fatigue effects in the contralateral limb (CL) can occur at intervals of up to 48 h after a training session performed with the ipsilateral limb. The objective of this study was to ver...

Background: Magnetic resonance imaging (MRI) is a well-used technique to assess muscle size and can be acquired on different planes. Pectoralis major (PM) and triceps brachii (TB) muscles are often acquired and analyzed on the axial plane, however it is unknown if anatomical cross-sectional area (CSA) calculated from different planes will affect t...

The first aim was to investigate the impact of different EMG parameters as a reference to normalize the EMG amplitude of the superficial quadriceps femoris muscles across different sets of a knee extension exercise. The second aim is to examine the reliability between days of the EMG parameters used as a reference. Eleven young males attended the l...

Exercise-induced muscular overload can trigger delayed onset muscle soreness (DOMS). DOMS is related to the indiscriminate use of analgesics and nonsteroidal anti-inflammatory drugs without proper guidance, decreased physical exercise adherence and degenerating sports performance, increased risk of injury, and reduced muscle strength and function....

Muscle volume (MV) and anatomical cross-sectional area (CSA) are used as measures of muscle-size, but determining these from magnetic resonance imaging (MRI) is a very time-consuming process. Additionally, it is unclear if the use of different muscle size assessments (all vs. reduced number of slices images) would impact the muscle size-strength re...

O Y-Balance Test (YBT) foi desenvolvido como um teste de equilíbrio dinâmico e seu desempenho tem sido associado com lesões de membros inferiores. O teste requer que o sujeito controle seu corpo em um apoio unilateral, o que sugere que a força de membros inferiores esteja relacionada com seu desempenho.

A força e o equilíbrio representam importantes componentes da aptidão física relacionada ao desempenho e a saúde. A relação entre força e equilíbrio tem demonstrado resultados contraditórios, sendo que o esclarecimento desta informação pode impactar diretamente no treinamento destes componentes. Propõe-se analisar a associação entre a força máxima...
