ISOTONIC EXERCISE PROVOKES GREATER THERMAL TENDINOUS STRESS THAN ISOMETRIC EXERCISE INDEPENDENT OF PHOTOBIOMODULATION

This is an experimental, randomized, single-blind study. A total of 32 healthy, physically active volunteers were randomly assigned to one of two independent groups who performed isometric (GISM, N=16, 8 Males/8 Females) or isotonic (GIST, N=16, 8 Males/8 Females) exercise protocols for the Sural Triceps preceded by the application of real PBM and Sham with a one-week washout. The subjects were evaluated by infrared thermography (IT), isometric muscle strength (IMS), pain and rating of perceived exertion (RPE), before, during and after performing the experimental protocols.

本研究为一项实验性随机单盲研究。共计纳入32名健康且体力活动活跃的志愿者，按随机原则将其分配至两个独立组别：等长运动组（GISM，N=16，男性8名、女性8名）与等张运动组（GIST，N=16，男性8名、女性8名），两组均针对腓肠三头肌（Sural Triceps）实施对应运动方案。所有受试者均先后接受真实光生物调节（Photobiomodulation, PBM）与假对照干预，两次干预间隔1周洗脱期。随后分别在实验方案实施前、实施过程中及实施结束后，通过红外热成像（infrared thermography, IT）、等长肌肉力量（isometric muscle strength, IMS）检测、疼痛评估及自觉劳累分级量表（rating of perceived exertion, RPE）对受试者进行测评。
