The player to receive has to decide whether to play until 9th or until 10th point. We observe in this paper that the score of the squash game can be modelled as a Markov chain. Thus using standard techniques of Markov processes, we can derive the optimal strategy for the squa...

The impairment of vision, especially the blindness, generates specific kind of locomotion with characteristic bending of body, stepping gate, short steps etc. (Dziedzic, 1980). It creates, among other things, characteristic anterior and backward curvatures of spine. Sport activity by playing sport games influences the values of the curvatures in sagittal plane only in small part. However the ef...

I read the article entitled “Effect of Lumbar Stabilization and Dynamic Lumbar Strengthening Exercises in Patients With Chronic Low Back Pain” by Moon et al. [1] with interest. However, I would like to offer some comments regarding its results and methodology reported. Moon et al. [1] compared ‘Lumbar Stabilization’ exercises with ‘Dynamic Lumbar Strengthening’ exercises. However the exercises ...
