To examine the effects of 12 weeks aquatic high-intensity interval training (AHIIT) compared with aquatic moderate-intensity continuous training (AMICT) on aerobic capacity and lower limb functional strength in adults with rheumatic and musculoskeletal diseases (RMDs).
An assessor-blinded randomised controlled trial.
Community-based setting.
89 participants (91% female, mean age 62 (SD 13) years) with RMDs were randomly allocated to AHIIT (n=44) or AMICT (n=45).
Both groups participated in group-based peer-led exercise programmes two times per week for 12 weeks. The AHIIT group included four intervals of 4 min at high intensity (Borg scale 14-18). The AMICT group maintained moderate continuous intensity level (Borg scale 12-13).
Peak aerobic capacity (VOpeak) was estimated by time to exhaustion and lower limb functional strength with the 30-second sit-to-stand test (30sSTS) at baseline, 3 months and 6 months. A linear mixed model for repeated measures estimated the mean difference with 95% CI in VOpeak and 30sSTS.
Mean exercise intensity was Borg scale 15 (SD 2) and 13 (SD 2) in the AHIIT and AMICT, respectively. Mean improvement in VOpeak in AHIIT was 1.9 mL∙kg∙min (95% CI 0.045 to 3.77) compared with AMICT after 12 weeks (p<0.05). There was no statistically significant difference between groups in VOpeak after 6 months or in 30sSTS at either 3 or 6 months (p>0.05). No adverse events during exercise were reported.
AHIIT demonstrated significant improvements in aerobic capacity after 12 weeks, and the intervention was well tolerated with no adverse events reported. However, there was no maintenance of aerobic capacity at 6 months.

探讨与水上中等强度持续训练（AMICT）相比，12周水上高强度间歇训练（AHIIT）对患有风湿性和肌肉骨骼疾病（RMDs）的成年人有氧能力和下肢功能力量的影响。
一项评估者盲法随机对照试验。
基于社区的环境。
89名患有RMDs的参与者（91%为女性，平均年龄62（标准差13）岁）被随机分配到AHIIT组（n = 44）或AMICT组（n = 45）。
两组均每周参加两次由同伴主导的小组锻炼计划，为期12周。AHIIT组包括四个4分钟的高强度间歇（Borg量表14 - 18）。AMICT组维持中等持续强度水平（Borg量表12 - 13）。
在基线、3个月和6个月时，通过力竭时间估计峰值有氧能力（VOpeak），并通过30秒坐立试验（30sSTS）评估下肢功能力量。重复测量的线性混合模型估计了VOpeak和30sSTS中具有95%置信区间的平均差异。
AHIIT组和AMICT组的平均运动强度分别为Borg量表15（标准差2）和13（标准差2）。12周后，与AMICT组相比，AHIIT组VOpeak的平均改善为1.9 mL∙kg∙min（95%置信区间0.045至3.77）（p<0.05）。6个月后两组在VOpeak方面或3个月和6个月时在30sSTS方面均无统计学显著差异（p>0.05）。未报告运动期间的不良事件。
AHIIT在12周后显示出有氧能力的显著改善，且该干预耐受性良好，未报告不良事件。然而，6个月时有氧能力没有维持。
NCT05209802。
