Eight male academy football players completed two, 2-week intervention trials: six IPC episodes (4 × 5 min at 220 mmHg per episode), and six SHAM episodes (4 × 5 min at 20 mmHg per episode). Prior to and following each intervention trial, the participants completed assessments of anaerobic performance (Running Anaerobic Sprint Test [RAST]), and superficial femoral artery endothelial function (flow-mediated dilation [FMD]).

To quantify the biomechanical response of the hockey-specific running gait, twelve field hockey players completed treadmill running at speeds of 6, 9 and 12 km·hr<sup>-1</sup> with a normal running gait and whilst manipulating the hockey stick to replicate dribbling. Mechanical loading was quantified using tri-axial accelerometery at L4, and muscular activity was measured for biceps femoris (BF), gluteus medius (GM) and quadratus lumborum (QL) of each limb. Running with the stick elicited greater mechanical loading in the medio-lateral (<i>p</i> = 0.001) and antero-posterior (<i>p</i> = 0.003) planes, and increased peak (<i>p</i> = 0.004) and mean (<i>p</i> = 0.002) EMG response of QL (<i>p</i> = 0.004). The greater planar mechanical loading and QL activation in response to hockey-specific running technique support epidemiological observations of lower back pain prevalence.
