概括

在老年人中,预测备用重复 (RIR) 可能缺乏准确性. 虽然RIR可以帮助与RPE一起进行体积监测,但它的准确性有限,特别是在较低的RIR值.

科学领域:

运动生理学
老年学
生物力学

背景情况:

耐力运动对于保持老年人的健康至关重要.
储备中的重复 (RIR) 是衡量运动强度的一种方法.
在老年人中预测RIR的有效性需要研究.

研究的目的:

在社区生活的老年人中评估预测RIR的准确性.
将预测的RIR与实际的RIR,速度损失和RPE进行比较.
确定预测RIR对于运动处方和监测在这个群体中的有用性.

主要方法:

25名老年人 (68±4岁) 熟悉RE,RIR和RPE.
进行一次重复测试 (1RM) 和重复到失败测试.
参与者执行了65%的1RM到预测的RIR为2,4和6,并记录了速度和RPE.

主要成果:

预测的RIR-2 (16%) 和RIR-4 (10%) 发生了显著的速度损失,而不是RIR-6 (0%).
参与者低估了RIR-2 (-2.1次) 和RIR-4 (-1.6次) 的重复,但没有低估RIR-6 (0.1次).
在预测的RIR值中,RPE显示出有限的灵敏度,表明潜在的不准确性.

结论:

预测的RIR可能缺乏准确的RE处方在老年人.
如果与RPE相结合,RIR可以用于监测训练量.
需要进一步的研究来完善老年人运动处方中的RIR使用.

Exercise and Muscle Performance

Exercise and Muscle Performance

Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
