Abstract

Objectives

Assess the repeatability of exercise-induced hypoalgesia (EIH) following low-load resistance exercise with blood flow restriction (LL + BFR) and the magnitude of EIH following LL + BFR, high-load resistance exercise, and a control intervention 1-h after exercise.

Design

Crossover design.

Setting

University laboratory.

Participants

15 females, 15 males.

Main outcome measures

Pain pressure threshold and tolerance of the rectus femoris, gastrocnemius, and biceps brachii pre-exercise and 0-, 15-, 30-, 45-, and 60-min post-exercise.

Results

There was no significant (p = 0.211–0.741) difference in pain pressure threshold or tolerance between LL + BFR1 and LL + BFR2 suggesting that EIH following LL + BFR is repeatable. LL + BFR elicited a significant (p = 0.001–0.043) increase in local pain pressure threshold (1.57 ± 1.21–0.98 ± 1.48 Δkgf) and tolerance (1.98 ± 2.65–0.83 ± 2.15 Δkgf) up to 1-h post-exercise. High-load resistance exercise elicited a significant (p = 0.003–0.034) increase in pain pressure threshold 0-min post-exercise (1.69 ± 1.74 Δkgf) and tolerance 0- and 15-min post-exercise (2.31 ± 2.44 Δkgf; 0.56 ± 1.83 Δkgf, respectively) then returned to pre-exercise levels. LL + BFR elicited a significant (p = 0.025–0.046) increase in systemic pain pressure tolerance (0.77 ± 0.88 Δkgf) of the gastrocnemius as well as pain pressure threshold (0.53 ± 0.54 Δkgf) and tolerance (0.49 ± 1.02 Δkgf) of the biceps brachii, when collapsed across Time.

Conclusions

LL + BFR may be a repeatable, effective pain management intervention that can produce prolonged EIH.

期刊介绍： Physical Therapy in Sport is an international peer-reviewed journal that provides a forum for the publication of research and clinical practice material relevant to the healthcare professions involved in sports and exercise medicine, and rehabilitation. The journal publishes material that is indispensable for day-to-day practice and continuing professional development. Physical Therapy in Sport covers topics dealing with the diagnosis, treatment, and prevention of injuries, as well as more general areas of sports and exercise medicine and related sports science. The journal publishes original research, case studies, reviews, masterclasses, papers on clinical approaches, and book reviews, as well as occasional reports from conferences. Papers are double-blind peer-reviewed by our international advisory board and other international experts, and submissions from a broad range of disciplines are actively encouraged.
