Sports anaemia is a physiological activity that occurs amongst footballers and may be due to poor diet, over-training, as well as an increase in plasma volume in endurance training activities. High plasma volume leads to changes in haematological parameters that may impact on endurance of footballers. The objective of the study was to determine the correlation between haematological and an-thropometric indices and their role in sports anaemia in a tropical setting.
Venous blood was taken into EDTA for 12 soccer players of KNUST soccer team before training and after training for the first (W1) and fifth (W5) weeks of training sessions. Complete blood count analysis was done for each blood sample and anthropometric parameters such as height, weight, body mass index, body fat percent and lean body mass were also measured. Cross-tabulations with mean and standard deviation or median and range were computed. Paired t-test & and Mann-Whitney test for parametric and non-parametric data computations were carried out and a p-value ≤ 0.05 was taken to rep-resent significant difference between data groups.
There was significant reduction in haemoglobin (p = 0.003), haematocrit (p = 0.002), mean cell volume (MCV) (p = 0.034) and red blood cell (RBC) count (p = 0.011) as a result of a significant expansion of plasma volume (p= 0.006). Neutrophil, lymphocyte and eosinophil counts were reduced significantly (p= 0.043, 0.001 and 0.007, respectively) after the training at W5. Lean body mass (LBM) inversely correlated with haemoglobin (r = -0.787, p = 0.002) and haematocrit (r = -0.588, p = 0.044). Body fat percentage (BFP) also negatively correlated with lymphocyte count (r = -0.700, p = 0.011). Furthermore, there was a positive correlation between body mass index (BMI) and plasma volume change after the training programme (r = 0.689, p = 0.013).
The results suggest that sports anaemia was induced by an increase in plasma volume that resulted in changes in haematological parameters.
运动性贫血是足球运动员中出现的一种生理现象,可能归因于饮食不良、过度训练以及耐力训练活动中血浆量的增加。高血浆量会导致血液学参数发生变化,这可能会影响足球运动员的耐力。本研究的目的是确定在热带环境下血液学指标与人体测量指标之间的相关性及其在运动性贫血中的作用。
采集了库马西科技大学足球队12名足球运动员在训练前以及训练第一周(W1)和第五周(W5)训练后的静脉血,置于乙二胺四乙酸(EDTA)抗凝管中。对每份血样进行全血细胞计数分析,并测量身高、体重、体重指数、体脂百分比和瘦体重等人体测量参数。计算了带有均值和标准差或中位数和范围的交叉表。对参数数据和非参数数据进行配对t检验和曼-惠特尼检验,p值≤0.05表示数据组之间存在显著差异。
由于血浆量显著增加(p = 0.006),血红蛋白(p = 0.003)、血细胞比容(p = 0.002)、平均红细胞体积(MCV)(p = 0.034)和红细胞(RBC)计数(p = 0.011)显著降低。在W5训练后,中性粒细胞、淋巴细胞和嗜酸性粒细胞计数显著减少(分别为p = 0.043、0.001和0.007)。瘦体重(LBM)与血红蛋白(r = -0.787,p = 0.002)和血细胞比容(r = -0.588,p = 0.044)呈负相关。体脂百分比(BFP)也与淋巴细胞计数呈负相关(r = -0.700,p = 0.011)。此外,训练计划后体重指数(BMI)与血浆量变化呈正相关(r = 0.689,p = 0.013)。
结果表明,运动性贫血是由血浆量增加导致血液学参数变化引起的。
