Great to see our research being implemented to aid the return of international cricket! @LboroSSEHS @lborosportsbiom @ECB_cricket https://twitter.com/ESPNcricinfo/status/1263892762815901701

18-22 year old fast bowlers demonstrate over double the incidence of lumbar stress fracture compared with the average incidence

Fast bowlers demonstrate rapid decreases of bone mineral density and content within the lumbar spine within 8-weeks of cessation of bowling.

Reversal of this loss of bone is likely dependent on return to bowling at near-match intensity and workloads - In stress fracture cases this can take in excess of 30-weeks post diagnosis of injury (ongoing PhD work).

Peak 7-day, 28-day and 90-day workload spikes significantly greater in fast bowlers who subsequently went on to sustain lumbar stress fracture within the same season https://bmjopensem.bmj.com/content/5/1/e000529
