摘要

目的:探讨在半深蹲运动中,在不同压力(40%和60%)下施加血流限制(BFR)对10次最大重复(10RM)时眼压(IOP)的影响。方法:采用准实验、前瞻性研究方法,选取17名健康体力活动者(男9名,女8名;(24.1±4.2年)。举行了两届会议。在第一个会话中确定了10RM负载。第二阶段包括在三种BFR条件下(无BFR、40%-BFR和60%-BFR)的10RM,以随机顺序应用。在每个条件前、每次重复后立即和被动恢复1分钟后测量眼压。IOP测量采用双向重复测量方差分析(限制类型[无bfr, 40%-BFR和60%-BFR] x测量点[基础,重复1-10次和恢复])。结果:由于60% BFR组的平均IOP值(19.0±0.7 mmHg)明显高于无BFR组(18.0±0.8 mmHg),因此观察到BFR状况的显著主要影响(p = 0.022, ƞp2 = 0.21);P = 0.048, dunb = 1.30)。60%-BFR和40%-BFR之间无显著差异(18.1±0.8 mmHg;p = .081 dunb = 1.16)和-bfr no-BFR至40% (p = .686 dunb = 0.18)。从基线到最后一次重复,IOP增加了大约3-4毫米汞柱。结论:低压BFR (40%-BFR)联合中负荷(10RM负荷)阻力训练是一种有效且安全的力量训练策略,同时避免了与大负荷阻力训练相关的IOP峰值。这些发现为需要维持稳定IOP水平的个体(例如青光眼患者)提供了最有效的运动策略。

Acute Intraocular Pressure Responses to Resistance Training in Combination With Blood Flow Restriction.

Objective: To determine the effect of blood flow restriction (BFR) applied to the legs at different pressures (40% and 60%) on intraocular pressure (IOP) during the execution of ten repetitions maximum (10RM) in the half-squat exercise. Methods: Quasi-experimental, prospective study with 17 healthy physically active subjects (9 males and 8 females; 24.1 ± 4.2 years). Two sessions were conducted. The 10RM load was determined in the first session. The second session consisted of 10RM under three BFR conditions (no-BFR, 40%-BFR, and 60%-BFR) that were applied in random order. IOP was measured before each condition, immediately after each repetition, and after 1 minute of passive recovery. A two-way repeated-measures ANOVA (restriction type [no-BFR, 40%-BFR, and 60%-BFR] x measurement point [basal, repetitions 1-10, and recovery]) was applied on the IOP measurements. Results: A significant main effect of the BFR condition (p = .022, ƞp2 = 0.21) was observed due to the significantly higher mean IOP values for the 60%-BFR (19.0 ± 0.7 mmHg) compared to the no-BFR (18.0 ± 0.8 mmHg; p = .048, dunb = 1.30). Non-significant differences with a large effect size were reached between 60%-BFR and 40%-BFR (18.1 ± 0.8 mmHg; p = .081, dunb = 1.16) and between no-BFR and 40%-BFR (p = .686, dunb = 0.18). IOP increased approximately 3-4 mmHg from baseline to the last repetition. Conclusions: Low-pressure BFR (40%-BFR) in combination with moderate-load (10RM load) resistance exercise could be an effective and safe strength training strategy while avoiding IOP peaks associated with heavy-load resistance exercises. These findings incorporate novel insights into the most effective exercise strategies in individuals who need to maintain stable IOP levels (e.g., glaucoma patients).

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
