摘　　要：为探讨运动训练对大学生龙舟选手无氧爆发力和肌肉厚度的影响,选取25名大学生龙舟选手为研究对象,在训练期前后,采用功率自行车分别测定上肢和下肢最大磷酸功率(ACP)与乳酸无氧功率(ALP),ACP和ALP的运动负荷时间分别为7 s和40 s。采用B型超声仪测定受试者11个部位的肌肉厚度。结果显示,训练前后受试者的ACP和ALP差异有统计学意义。运动训练后不仅上臂前后部、胸部和肩胛骨下角等肌肉厚度显著增加,同时上臂屈肌群、上臂伸肌群和大腿屈肌群生理横断面积与运动训练前比较显著增加。然而与运动训练前比较下肢蹬踏ALP无显著增加,大腿伸肌群生理横断面积却显著下降。结果表明,在大学生龙舟选手身体训练期间,根据其生理特征加强腿部ALP爆发力和大腿伸肌群的训练极为重要。This study aimed to study the effects of physical training on anaerobic power and muscle thickness of dragon boat athletes in colleges. The 25 college students participated in the experiment for four cycle ergometer work tests,and continued lasting 7 and 40 seconds,which was used to estimate ATP- CP power（ ACP） and anaerobic lactic power（ ALP） with leg（ pedaling） and arm（ cranking） exercises. ACP was obtained as the highest power output during 7 seconds,and ALP was measured as the mean power output during 40 seconds. Muscle thickness was measured by B- mode ultrasonography at 11 sites on the subject＇s body. The results showed that improvements in leg ALP and knee extensor muscle are necessary during the physical training program of male college dragon boat athletes.
