The purpose of this study was to investigate the hematological and inflammatory responses to 4 maximal high-intensity protocols, considering energy expenditure in each test. 9 healthy volunteers performed 4 high-intensity exercise tests of short [Wingate (WANT); Repeated-sprints (RSA)] and long durations [Continuous VO test (VCONT); intermittent VO test (VINT)] in a cycle-ergometer, until exhaustion. Hematological parameters and IL-6, IL-10 and creatine kinase (CK) levels were determined before (PRE), POST, 30 min, 1, 2, 12 and 24 h after the end of the protocols. Additionally, energy expenditure was determined. Leucocytes, erythrocytes and lymphocytes increased at POST and returned to PRE values at 30 min for all protocols. Lymphocytes had a second decreased at 2 h and granulocytes increased at 2 h when compared to PRE. Both variables returned to PRE values between 12-24 h into recovery. The magnitude of response for IL-6 was greater in VINT and for IL-10 in VCONT. There was no association of energy expenditure within each exercise protocol with the pattern of IL-6, IL-10 and CK responses to the exercise protocols. The present finding support that similar responses after continuous or intermittent acute protocols are observed when exercises are performed to volitional failure, regardless of the duration and mode of exercise.
本研究的目的是研究在考虑每次测试能量消耗的情况下，对4种最大强度方案的血液学和炎症反应。9名健康志愿者在功率自行车上进行了4次短时间[温盖特（WANT）；重复冲刺（RSA）]和长时间[持续VO₂测试（VCONT）；间歇VO₂测试（VINT）]的高强度运动测试，直至精疲力竭。在方案结束前（PRE）、结束后、30分钟、1小时、2小时、12小时和24小时测定血液学参数以及白细胞介素-6（IL-6）、白细胞介素-10（IL-10）和肌酸激酶（CK）水平。此外，还测定了能量消耗。所有方案中，白细胞、红细胞和淋巴细胞在运动后增加，并在30分钟时恢复到运动前水平。与运动前相比，淋巴细胞在2小时时再次减少，粒细胞在2小时时增加。这两个变量在恢复12至24小时之间恢复到运动前水平。VINT中IL-6的反应幅度更大，VCONT中IL-10的反应幅度更大。每个运动方案中的能量消耗与运动方案中IL-6、IL-10和CK反应模式之间没有关联。目前的研究结果支持，当运动至自愿疲劳时，无论运动持续时间和方式如何，在连续或间歇急性运动方案后都会观察到相似的反应。
