摘要: 目的:研究周期类运动能量消耗C指标在评价乒乓球多球练习中能量消耗应用的可行性。方法:11名某大学代表队的乒乓球运动员(18±1 yrs, 177±2 cm, 71±3 kg,运动水平≥二级)自愿参加了1次跑台递增负荷测试和2次(正手和反手)发球机多球递增频率测试(3 min × 6级,频率为35~85 stroke·min-1)。用便携式气体代谢仪和心率监测仪检测3次测试的呼吸气体和心率,计算每种频率下每次击球所消耗的能量;采集运动前后的耳血进行血乳酸分析。结果:乒乓球前冲弧圈多球练习的能量消耗C随击球频率的增加而下降(P<0.05)。6种击球频率下,正手前冲弧圈的能量消耗C都高于反手,且差异在35、45、55、65和85 stroke·min-1时显著(P<0.05)。能量消耗C与频率的关系公式分别为y=166.4x-0.731(R2=0.9731)和y=33.21x-0.392(R2=0.8423),其中y为能量消耗C(单位为J·stroke-1·kg-1),x为击球频率(单位为stroke·min-1)。结论:周期类运动项目的能量消耗C可应用于评价乒乓球运动员单一技术动作多球练习的能量消耗,反映乒乓球运动员在不同击球频率下的击球效率。

Abstract: Objective: To investigate the feasibility of applying the measure of energy cost, utilized widely in cyclic sports, in table tennis multi-ball practice. Methods: Eleven collegiate table tennis players volunteered (18±1 yrs, 177±2 cm, 71±3 kg, approximately 10 yrs’ training experience) to participate in one graded exercise test on treadmill, and two step tests (forehand and backhand, 3 min × 6, 35~85 stroke/min). A portable spirometric system and heart rate monitor were utilized for the three trials. Earlobe blood samples were collected and analyzed prior to and post the test. Energy cost was calculated for one stroke at each stroke frequency. Results: The energy cost of loop drive multi-ball practice was decreased with increased stroke frequency (P<0.05). The energy cost of forehand loop drive was higher than backhand, with the difference significant at 35, 45, 55, 65, and 85 stroke·min-1 (P<0.05). The function between energy cost and frequency were y=166.4x-0.731 (R2=0.9731), and y=33.21x-0.392 (R2=0.8423), respectively, where y was energy cost, and x was stroke frequency. Conclusion: The measure of energy cost utilized in cyclic sports could be applied to evaluate the energy expenditure in table tennis multi-ball practice of single technique, and indicate the stroke efficiency of table tennis muti-ball practice with different stroke frequencies.
