This study investigated the combined effects of competition area (4 × 4, 6 × 6, and 8 × 8 m) and judo-specific training type (tachi-waza, ne-waza, and free randori) on physiological responses and perceived exertion in female judo athletes. In a within-subject design, 12 female subelite and elite athletes who competed at regional or national levels with a mean training background of 8.4 ± 0.5 years performed the experimental conditions (i.e., combats (viz., matches) featuring different area/training type combinations) in random order. The following measurements at different time points were chosen: blood lactate before and after each match; heart rate before, mean, and peak for each match; and rating of perceived exertion immediately after each match. Two-factor analysis of variance was used to compare between conditions, while Bonferroni post hoc test and magnitude of difference were used to measure significance. There was no main effect of training type or area size on lactate before each match, heart rate (HR) before each match, HR mean during each match, and rating of perceived exertion. Main effects of training type and area size were found for lactate after each event, with the values being greater in free randori compared to tachi-waza and ne-waza and in 4 × 4 m compared to 6 × 6 and 8 × 8 m area. Main effects of training type and area size were also found in peak heart rate, with lower values in ne-waza compared to free randori and tachi-waza and in 8 × 8 m compared to 4 × 4 m area. The results demonstrate that varying training modality and area size may alter physiological responses during female judo combats by putting stress on the cardiovascular system and increasing anaerobic glycolysis solicitation.
本研究调查了竞争区域(4×4、6×6 和 8×8 米)和柔道专项训练类型(投技、寝技和自由型比赛)对女性柔道运动员生理反应和感知用力的综合影响。在一项被试内设计中,12 名参加过区域性或国家级比赛的次精英和精英女性运动员(平均训练背景为 8.4±0.5 年)以随机顺序完成了不同区域/训练类型组合的实验条件(即具有不同区域/训练类型组合的比赛)。选择了以下不同时间点的测量:每次比赛前后的血乳酸;每次比赛前后的心率,每次比赛的平均心率和峰值心率;以及每次比赛后的感知用力评分。使用双因素方差分析比较条件之间的差异,使用 Bonferroni 事后检验和差异幅度来衡量差异的显著性。在每次比赛前的血乳酸、每次比赛前的心率、每次比赛期间的平均心率和感知用力评分方面,训练类型和区域大小均无主要影响。在每次比赛后的血乳酸和心率方面,发现了训练类型和区域大小的主要影响,自由型比赛的血乳酸值大于投技和寝技,4×4 米区域的血乳酸值大于 6×6 和 8×8 米区域。在峰值心率方面,也发现了训练类型和区域大小的主要影响,寝技的峰值心率低于自由型比赛和投技,8×8 米区域的峰值心率低于 4×4 米区域。研究结果表明,通过对心血管系统施加压力和增加无氧糖酵解需求,改变训练模式和区域大小可能会改变女性柔道比赛中的生理反应。
