study of top irish jockeys
Study of Top Irish Jockeys
  • 18 Flat (6 Apprentices)

  • Whole Body Dexa Scan

  • 14 Jockeys Volunteered
  • Urine samples collected over the day’s racing
  • All 14 Jockeys were dehydrated
  • 93% had high to severe levels of dehydration
  • Dehydration increased during the course of the day
  • Similar findings to a pilot study McGoldrick et al 2003
haematology
Haematology

In a number of Jockeys evidence of:

  • Deficiency in trace elements
  • Iron deficiency anaemia
  • Vitamin deficiency
  • Low white cell count
  • Borderline thyroid function
  • Compromised renal function
summary of other key findings
Summary of other key findings
  • 54% of Flat & 40% of N Hunt osteopenic in either spine, hip or both
  • Compared to age matched males 20% (spine) 8% (hip)
  • The 6 Apprentices had the lowest BMI and body fat levels and the worst problems with bone mineral density, 4 being osteopenic, 2 osteoporotic
summary of other key findings19
Summary of other key findings
  • 88% of Flat and 70% of N Hunt had body fat levels of 10% or less with some as low as 6%
  • Body fat range for health (men) 13-18%

  • Flat ate a third, NH ate less than ½ of fibre RDA
