The study examined the effect of aerobic and sprint sets sequence on physiological responses and perceived exertion during concurrent training sessions. Twelve male highly trained swimmers performed four sessions in randomized order, using combinations of the following training sets: (a) lactate threshold training (8 × 200-m at a speed corresponding to lactate threshold with 30-s recovery; LT), (b) high-intensity aerobic training (8 × 100-m at the maximal aerobic speed with 30-s recovery; MAS) and (c) repeated-sprints training (8 × 25-m repeated sprints with 2-min recovery; SPR). The four combinations used were as follows: LT-SPR, SPR-LT, MAS-SPR, SPR-MAS. Blood lactate (BL), pH, base excess (BE), bicarbonate, heart rate (HR), HR variability, objective [training impulse (iTRIMP)] and subjective training load [session's rating of perceived exertion (sRPE)] were measured. Between session pH and BE were no different, but mean BL was higher in sessions starting with repeated sprints compared with the reverse order (SPR-LT: 6.3 ± 3.6, LT-SPR: 5.3 ± 3.7 mmol·L, = 0.03; SPR-MAS: 7.2 ± 3.9, MAS-SPR: 6.0 ± 3.7 mmol·L, = 0.05). Bicarbonate in SPR-LT was lower compared with LT-SPR ( = 0.03). sRPE, but not iTRIMP, was higher in sessions starting with SPR compared with the reverse order ( = 0.02). Anaerobic-aerobic set sequence, compared with the reverse order, augments BL response and increases perceived training load but not the training impulse.
该研究考察了有氧训练组和冲刺训练组顺序对同时进行训练期间生理反应和主观用力感觉的影响。12名男性高水平游泳运动员以随机顺序进行了4次训练，采用以下训练组的组合：(a)乳酸阈训练(8组200米，速度对应乳酸阈，恢复30秒；LT)，(b)高强度有氧训练(8组100米，最大有氧速度，恢复30秒；MAS)，以及(c)重复冲刺训练(8组25米重复冲刺，恢复2分钟；SPR)。使用的四种组合如下：LT-SPR、SPR-LT、MAS-SPR、SPR-MAS。测量了血乳酸(BL)、pH值、碱剩余(BE)、碳酸氢盐、心率(HR)、心率变异性、客观训练强度[训练冲量(iTRIMP)]和主观训练负荷[训练课的主观用力感觉评分(sRPE)]。各训练课之间pH值和BE无差异，但与相反顺序相比，以重复冲刺开始的训练课平均BL更高(SPR-LT：6.3±3.6，LT-SPR：5.3±3.7 mmol·L，P = 0.03；SPR-MAS：7.2±3.9，MAS-SPR：6.0±3.7 mmol·L，P = 0.05)。与LT-SPR相比，SPR-LT中的碳酸氢盐更低(P = 0.03)。与相反顺序相比，以SPR开始的训练课sRPE更高，但iTRIMP无差异(P = 0.02)。与相反顺序相比，无氧-有氧训练组顺序增强了血乳酸反应，增加了主观训练负荷，但未增加训练冲量。
