The aim of this study was to assess on a large series of soccer players our previous reports on blood rheology and exercise performance. In 99 soccer players (Age 24,17 ± 0,42 yr; weight 75,87 ± 0,89 kg; VO2max 46,86 ± 0,95 mL/min/kg) an exercise test was performed for measuring maximal aerobic capacity and we measured blood viscosity at high shear rate (MT90 viscometer) and RBC aggregation (Myrenne MK1). The French questionnaire developped by the consensus group on overtraining of the French Society of Sports Medicine (SFMS) was also employed. The only hemorheologic statistical determinant of VO2max was hematocrit (Hct r = -0.2439; p = 0.0303). The lactate threshold 2 mmol/l was negatively correlated to M1 (r = -0.43224; p = 0.00847). There was a borderline correlation between the overtraining score at the questionnaire of the SFMS and plasma viscosity (r = 0.3080; p = 0.0532). Therefore, our study confirms that aerobic capacity in this sport is negatively correlated to hematocrit, that RBC aggregation is positively associated with blood lactate accumulation in blood during exercise, and that plasma viscosity is one of the parameters that increase when the athlete is on the edge of the overtraining syndrome. These data are consistent with previous reports about soccer players but caution is needed to extrapolate to other sports.
本研究的目的是在大量足球运动员中评估我们以前关于血液流变学和运动表现的报告。在 99 名足球运动员(年龄 24.17 ± 0.42 岁;体重 75.87 ± 0.89 公斤;最大摄氧量 46.86 ± 0.95 毫升/分钟/公斤)中进行了运动测试,以测量最大有氧能力,并且我们在高剪切率下测量了血液粘度(MT90 粘度计)和 RBC 聚集(Myrenne MK1)。还使用了由法国运动医学学会过度训练共识小组开发的法国问卷。唯一与最大摄氧量相关的血液流变学统计决定因素是血细胞比容(Hct r = -0.2439;p = 0.0303)。2 毫摩尔/升的乳酸阈与 M1 呈负相关(r = -0.43224;p = 0.00847)。SFMS 问卷中的过度训练评分与血浆粘度之间存在边界相关性(r = 0.3080;p = 0.0532)。因此,我们的研究证实,这项运动中的有氧能力与血细胞比容呈负相关,RBC 聚集与运动中血液中乳酸的积累呈正相关,血浆粘度是运动员处于过度训练综合征边缘时增加的参数之一。这些数据与以前关于足球运动员的报告一致,但需要谨慎推断到其他运动。
