Abstract
Individuals with a locomotor impairment (I-LI), in particular those with a spinal cord injury (SCI) display a high prevalence of the risk factors (RF) of the atherosclerotic cardiovascular disease (ACVD). Paralympic Athletes (PA) with a LI show a high prevalence of ACVD-RF in spite of their active lifestyle. We tested the hypotheses that the prevalence of ACVD-RF is influenced by the type of practiced sport (skill sport – SS; power sports – PS; intermittent sports – IS; endurance sports – ES) and is inversely related to oxygen uptake peak (VO2peak). Summer and winter male PA, 87 PA with either SCI or spina bifida (SB-SCI) and 74 PA with other health conditions (HC) determining a lower limb impairment (e.g., amputation, poliomyelitis, etc.), screened during the health and fitness evaluations preceding 8 Paralympic Games, underwent to anthropometric and blood pressure (BP) measurements and laboratory blood tests to estimate an ACVD-RF score. The latter was obtained summing 1 point for each RF: central obesity -OB (waist circumference ≥102 cm), hypertension -HT (rest systolic BP≥ 140 mmHg and/or diastolic BP≥ 90 mmHg), dyslipidemia -DL (total Cholesterol - TC≥200 mg/dl or LDL-C≥130 mg/dl or HDL-C<40 mg/dl), impaired fasting glucose -IG (fasting plasma glucose≥ 100 mg/dl) and subtracting 1 point with high serum HDL-C (≥60 mg/dl). All PA were submitted to an incremental cardiopulmonary maximal exercise test to assess VO2peak. Prevalence of ACVD-RF in different sport type were compared with Chi-squared. The differences in VO2peak between the 2 HC groups within different ACVD-RF classes were evaluated (two-way analysis of variance, Bonferroni corrected). The relationship between VO2peak and ACVD-RF was evaluated. Based on the ACVD-RF score, 3 groups (G) were formed: G1 (RF≤0), G2 (RF=1) and G3 (RF≥2). G1 (17 PA competing in ES, 15 in MS, 8 in PS and 10 in SS), G2 (10 PA in ES, 23 in MS, 13 in PS and 16 in SS) and G3 (3 PA in ES, 22 in MS, 5 in PS and 19 in SS) differed significantly for the prevalence of PA competing in different sports (p<0.01). VO2peak (ml/kg/min) of PA in G1 (34±9.9 and 38±9.4 respectively for PA with SB-SCI and with other HC) was higher than that of PA in G2 (29±7.8 and 34±6.1), which was higher than that of PA in G3 (24±6.7 and 31±9) (p<0.05). The following significant (p<0.001) regression was found: VO2peak= 34.92 - 3.49RF. Competing in ES and having high VO2peak values seem to provide a protective effect against the risk of developing ACVD.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
