Abstract

Modified exercise prescription in judo is commonly used to activate the energy systems in different magnitudes. In order to study the physiological and rating of perceived exertion (RPE) responses according to area sizes (i.e., 4 m × 4 m, 6 m × 6 m and 8 m × 8 m) and training mode variations (i.e., groundwork, ne-waza; standing combat only, tachi-waza; and free combat, free randori), eighteen male judo athletes (age: 22.6 ± 1.8 years) were randomly assigned, on separate days, to 9 experimental conditions (3 area sizes × 3 training modes) with each condition lasting 4 min. Delta lactate [La] was calculated based on the blood lactate values measured before and after every condition. Heart rate (HR) was measured during and after each bout and RPE recorded at the end of each combat. The results showed that mean and peak HR, percentage of maximum HR (% HRmax), delta [La] values and RPE scores were lower in 4 m × 4 m compared to 6 m × 6 m and 8 m × 8 m, and in groundwork training mode compared to standing combat and free randori (all p < 0.001). Furthermore, the 6 m × 6 m condition induced lower delta [La] values than 8 m × 8 m (p < 0.001) and free randori resulted in higher RPE scores than standing combat (p = 0.001). In conclusion, different training variables can be easily manipulated in a variety of different ways to specifically activate the energetic systems. Focusing on groundwork, the 6 m × 6 m area size was found to be the most suitable condition to induce a higher cardiovascular response, while the standing combat and free randori in 6 m × 6 m resulted in increased glycolytic activation compared to the groundwork condition.

在男子柔道比赛中,训练类型和区域大小的变化对生理反应和会话感知消耗反应评级的影响。
柔道运动中通常使用修改后的运动处方来激活不同强度的能量系统。为了研究不同面积(即 4 m × 4 m、6 m × 6 m 和 8 m × 8 m)和不同训练模式(即:地面练习,ne-waza;仅站立格斗,tachi-waza;自由格斗,free randori)下的生理反应和感知用力值(RPE)、18 名男性柔道运动员(年龄:22.6 ± 1.8 岁)在不同的日期被随机分配到 9 种实验条件(3 种面积大小 × 3 种训练模式)中,每种条件持续 4 分钟。Δ乳酸[La]是根据每个条件前后测量的血乳酸值计算得出的。在每次训练期间和之后测量心率(HR),并在每次战斗结束时记录 RPE。结果显示,与 6 米×6 米和 8 米×8 米相比,4 米×4 米的平均心率和峰值心率、最大心率百分比(% HRmax)、δ[La]值和 RPE 分数较低;与站立搏击和自由搏击相比,地面训练模式的平均心率和峰值心率、最大心率百分比(% HRmax)、δ[La]值和 RPE 分数较低(均 p <0.001)。此外,6 米 × 6 米条件下的 delta [La] 值低于 8 米 × 8 米条件下的 delta [La] 值(p < 0.001),自由转体导致的 RPE 分数高于站立格斗(p = 0.001)。总之,不同的训练变量可以很容易地通过各种不同的方式进行操作,从而有针对性地激活能量系统。就地面运动而言,6 米×6 米的场地大小最适合诱发较高的心血管反应,而与地面运动条件相比,6 米×6 米的站立搏击和自由兰多里导致糖酵解激活增加。
