We investigated the effects of resistance training on muscle buffer capacity, H regulation, and repeated-sprint ability (RSA).
Sixteen recreationally active females performed a graded exercise test to determine VO2peak and the lactate threshold (LT), a repeated-sprint test (5 x 6 s, every 30 s) to determine RSA, and a 60-s high-intensity exercise test based on their pretraining RSA score (CIT60; continuous cycling at approximately 160% VO2peak). Muscle biopsies (vastus lateralis) were sampled before and immediately after CIT60. Subjects were then randomly assigned to either a high-repetition (three to five sets of 15-20 reps) short-rest (20 s) resistance-training group or to a control group.
Training did not result in significant improvements in VO2peak (P > 0.05) but did improve the LT, leg strength, and RSA (P < 0.05). There were no significant improvements in muscle buffer capacity after training (P > 0.05); however, there was a significant reduction in H in the muscle and blood after high-intensity exercise (CIT60) (P < 0.05),
High-repetition, short-rest, resistance training does not improve muscle buffer capacity in active females, but it does reduce H accumulation during high-intensity exercise (approximately 160% VO2peak). It is likely that increases in strength, LT, and ion regulation contributed to the improved RSA.
我们研究了抗阻训练对肌肉缓冲能力、氢离子调节及反复冲刺能力（RSA）的影响。
16名有运动习惯的女性进行了递增运动测试以确定最大摄氧量（VO2peak）和乳酸阈（LT），进行了反复冲刺测试（5次×6秒，每30秒一次）以确定RSA，并根据她们训练前的RSA分数进行了60秒高强度运动测试（CIT60；以约160%VO2peak的强度持续骑行）。在CIT60之前和之后立即采集外侧股四头肌的肌肉活检样本。然后将受试者随机分为高重复次数（3至5组，每组15至20次重复）短休息（20秒）抗阻训练组或对照组。
训练并未使VO2peak有显著改善（P>0.05），但确实提高了LT、腿部力量和RSA（P<0.0
