Locomotor impaired (LI) individuals have higher atherogenic cardiovascular disease risk (ACDR) than able-bodied population, because of an altered lipid profile mainly due to their increased sedentary habit. The present study, carried out on a population of LI Paralympic athletes (LI-PA) who competed in the last summer Games (Beijing, 2008), was aimed at evaluating the hypothesis that aerobic fitness protects from ACDR.
A total of 44 male LI-PA (38±10.1 years old): 26 with spinal cord injury, 6 with amputation, 3 with cerebral palsy, 4 poliomyelitis and 5 with other neurological disorders were screened (anthropometric and clinical measurements and laboratory tests) and functionally evaluated (incremental maximal arm cranking exercise test) to estimate their ACDR and aerobic fitness (VO2peak), respectively. An ACDR score was assessed summing 1 point for each of the following risk factors: obesity, hypertension, dyslipidemia, impaired fasting glucose and subtracting 1 point when serum HDL cholesterol was higher than 60 mgdl-1. Based on the ACDR score 3 groups were formed: group 1 with low ACDR (score<=1); group 2 with moderate ACDR (score=2); group 3 with high ACDR (score>=3).
Group 1 (28 LI-PA), group 2 (8 LI-PA) and group 3 (8 LI-PA) had significantly different VO2peak values respectively equal to 34.8±7.76, 25.6±7.52 and 18.8±4.26 mlkg-1min-1 (p<0.05).
VO2peak is inversely related to ACDR. High aerobic fitness provides a protective effect on ACDR in LI-PA.
