短期极限负荷训练对武警男性官兵甲状腺功能血液指标的影响

 目的 探讨短期极限负荷训练对武警男性官兵甲状腺功能血液指标的影响,为科学安排训练负荷提供依据。方法 选取2018年10-11月武警某部68名男性士兵,分别在训练日7:00、极限训练1周后次日7:00空腹状态下各取静脉血3 ml,检测游离三碘甲状腺原氨酸(FT₃)、游离甲状腺素(FT₄)、促甲状腺素(TSH)、抗甲状腺球蛋白抗体(TGA)、抗甲状腺过氧化物酶抗体(TPOA)等指标。结果 TSH短期极限负荷训练后1.48(0.99,2.05)]μU/ml与训练前2.16(1.34,3.39)]μU/ml相比,明显降低,差异有统计学意义(P<0.05);而FT₃(3.95±0.41)pmol/L vs. (3.94±0.28)pmol/L ]、FT₄(12.27±1.24)pmol/L vs. (11.30±0.95)pmol/L]、TGA(2.17±1.34)U/ml vs. (2.14±1.30)U/ml]、TPOA(2.35±1.47)U/ml vs. (2.23±1.42)U/ml]等指标短期极限负荷训练后与训练前比较,差异均无统计学意义。结论 短期极限训练负荷对武警男性官兵甲状腺功能血液指标的影响较小,可视情安排极限负荷训练。

Effects of short-term ultimate load training on hematological indexes of thyroid function of Armed Police recruits

Objective To investigate the effects of short-term ultimate load training on the hematological indexes of thyroid function of Armed Police recruits. Methods Sixty-eight Armed Police recruits were chosen randomly between October and November of 2018.Venous blood was drawn at 7:00 a.m. before training and after seven days of ultimate load training. Such hematological indexes as FT₃,FT₄,TSH,TGA and TPOA were analyzed. Results There was no significant difference in hematological indexes except TSH between the samples before training and after training. The level of TSH decreased from2.16(1.34,3.39)]μU/ml to1.48(0.99,2.05)]μU/ml after training(P<0.05). After training, there were no significant change in the values of FT₃ (3.95±0.41) pmol/L vs. (3.94±0.28) pmol/L], FT₄ (12.27±1.24) pmol/L vs. (11.30±0.95) pmol/L], TGA (2.17±1.34) U/ml vs. (2.14±1.30) U/ml] or in TPOA (2.35±1.47) U/ml vs. (2.23±1.42) U/ml]. Conclusions Short-term ultimate load training has relatively little effect on hematological indexes of thyroid function among Armed Police recruits, so overload training should be organized as required.
