Introduction and objectives: The purpose of this study was to determine the effects of electrostimulation and core exercises on recovery after high-intensity exercise. Methods: The participants of this study consists of 12 male bodybuilders who regularly train and between the ages 18-30. Tabata high intensity interval training (HIIT) was applied with different recovery methods to the athletes on three different days and the recovery levels of athletes were analysed. Heart rate and blood lactate levels were measured at baseline (PRE) at immediately after the HIIT (POST), at the 1 minutes after HIIT (1min), at the 5 minutes after HIIT (5min), and at the 10 minutes after HIIT (10min). On the rest days, serum lactate dehydrogenase (LDH) and serum creatine kinase (CK) measurements were done to determine the muscle damage. Results: The in-group comparisons for lactate levels showed no significant difference (p>0,01). The level of lactate on the 10min was found to be significantly lower than the 5min in the core exercise group (p 0,01). These results show that the lactate level reaches to the maximum level after HIIT, and the level of lactate decreases between the 5th and the 10th minutes. Discussion and conclusion: These indicate that the active recovery methods are more effective than the passive. It was found that the active recovery methods accelerate the lactate removal from the metabolism and provide effective recovery in short time during the recovery period after exercise.

电刺激和核心锻炼对大强度运动后恢复的影响

引言和目的：这项研究的目的是确定高强度运动后电刺激和核心运动对恢复的影响。方法：本研究的参与者由12名男性健美运动员组成，他们定期训练且年龄在18至30岁之间。在3天的不同时间对运动员进行Tabata高强度间歇训练（HIIT），并分析运动员的康复水平。在HIIT（POST）之后，HIIT之后1分钟（1min），HIIT之后5分钟（5min）和HIIT之后10分钟（基线）的基线（PRE）处测量心率和血液乳酸水平（ 10分钟）。在休息日，进行血清乳酸脱氢酶（LDH）和血清肌酸激酶（CK）的测定以确定肌肉损伤。结果：乳酸水平的组内比较显示无显着差异（p> 0.01）。发现核心锻炼组在10分钟时的乳酸盐水平显着低于5分钟时（p 0,01）。这些结果表明，HIIT后乳酸水平达到最高水平，并且乳酸水平在第5分钟和第10分钟之间降低。讨论与结论：这些表明，主动恢复方法比被动方法更有效。研究发现，积极的恢复方法可以加速代谢过程中乳酸的去除，并在运动后的恢复期内在短时间内提供有效的恢复。这些结果表明，HIIT后乳酸水平达到最高水平，并且乳酸水平在第5分钟和第10分钟之间降低。讨论与结论：这些表明，主动恢复方法比被动方法更有效。研究发现，积极的恢复方法可以加速代谢过程中乳酸的去除，并在运动后的恢复期内在短时间内提供有效的恢复。这些结果表明，HIIT后乳酸水平达到最高水平，并且乳酸水平在第5分钟和第10分钟之间降低。讨论与结论：这些表明，主动恢复方法比被动方法更有效。研究发现，积极的恢复方法可以加速代谢过程中乳酸的去除，并在运动后的恢复期内在短时间内提供有效的恢复。
