This study investigated the effects of two different hydrostatic pressures (seated or standing) during cold water immersion at attenuating the deleterious effects of strenuous exercise on indices of damage and recovery. Twenty four male well-trained games players (age 23 ± 3 years; body mass 81.4 ± 8.7 kg: [Formula: see text]O2max 57.5 ± 4.9 ml∙kg(-1)∙min(-1)) completed the Loughborough Intermittent Shuttle Test (LIST) and were randomly assigned to either a control, seated cold water immersion or a standing cold water immersion (14 min at 14°C). Maximal isometric voluntary contraction, counter-movement jump, creatine kinase, C-reactive protein, interleukin-6 and delayed onset muscle soreness (DOMS) were measured before and up to 72 h following the LIST. All dependent variables showed main effects for time (P < 0.05) following the LIST, indicating physiological stress and muscle damage following the exercise. There were no significant group differences between control and either of the cold water immersion interventions. Seated cold water immersion was associated with lower DOMS than standing cold water immersion (effect size = 1.86; P = 0.001). These data suggest that increasing hydrostatic pressure by standing in cold water does not provide an additional recovery benefit over seated cold water immersion, and that both seated and standing immersions have no benefit in promoting recovery following intermittent sprint exercise.
本研究调查了冷水浸泡期间两种不同静水压力（坐姿或站姿）对减轻剧烈运动对损伤和恢复指标的有害影响。24名训练有素的男性运动员（年龄23±3岁；体重81.4±8.7 kg；最大摄氧量57.5±4.9 ml∙kg⁻¹∙min⁻¹）完成了拉夫堡间歇性穿梭测试（LIST），并被随机分配到对照组、坐姿冷水浸泡组或站姿冷水浸泡组（在14°C下浸泡14分钟）。在LIST之前和之后长达72小时测量最大等长自愿收缩、反向运动跳跃、肌酸激酶、C反应蛋白、白细胞介素-6和延迟性肌肉酸痛（DOMS）。所有因变量在LIST之后均显示出时间主效应（P<0.05），表明运动后存在生理应激和肌肉损伤。对照组与任何一种冷水浸泡干预组之间均无显著组间差异。坐姿冷水浸泡比站姿冷水浸泡的DOMS更低（效应量=1.86；P=0.001）。这些数据表明，在冷水中站立增加静水压力并不比坐姿冷水浸泡提供额外的恢复益处，并且坐姿和站姿浸泡在间歇性冲刺运动后促进恢复方面均无益处。
