The aim was to compare the activation of some lower leg muscles related to ankle joint control during running on tarmac and grass. The only significant difference occurred in tibialis anterior muscle in pre-activation phase with EMG amplitude higher running on tarmac. This showed that the runners prepared themselves for higher impact forces by increased muscle stiffness.

The aim of the present study was to analyze changes in muscle viscoelastic stiffness during reciprocal inhibition as a possible simple tool to measure muscle relaxation. Viscoelastic stiffness of m. soleus increased with the stronger plantar flexion, which followed the cross-bridge theory well. During stronger dorsal flexion, the H-reflex was increasingly reduced showing the presence of reciprocal inhibition. However, viscoelastic stiffness of m. soleus was increased. It seems that this method is not suitable for muscle relaxation assessment.

The aim of the research was to test efficiency of 8 month long balance training in active older subjects. After the training, movement of ground reaction force application point when standing on hard surface didn’t change, however, when standing on soft surface it did get smaller in medio-lateral and antero-posterior direction, with lower velocity of movement and reduced surface. With eyes closed, only reduction in antero-posterior direction was observed. The training resulted in also in increased walking velocity. All these changes showed that balance training performed twice per week is capable to improve balance in active older subjects.
