To describe the changes in the spinopelvic parameters in weight lifters and evaluate the factors leading to spinal anatomical changes (eg, spondylolysis and listhesis). ⋯ The elite weight lifters had increased lumbar lordosis and decreased PT compared with the healthy volunteers. The ULL/TLL ratio may be used as a predictive marker for lumbar deformation.

To investigate (1) cardiopulmonary resuscitation (CPR) adequacy during simulated cardiac arrest of equipped football players and (2) whether protective football equipment impedes CPR performance measures. ⋯ Chest compression depth is significantly decreased when performed over shoulder pads, while there is no apparent effect on rate or chest wall recoil. Although the clinical outcomes from our observed 15% difference in compression depth are uncertain, chest compression under the pads significantly increases the depth of compressions and more closely approaches American Heart Association guidelines for chest compression depth in cardiac arrest.
