BLOOD FLOW RESTRICTION TRAINING IN CLINICAL MUSCULOSKELETAL REHABILITATION: A SYSTEMATIC REVIEW AND META-ANALYSIS.
BJSM Online First, published on March 4, 2017 as 10.1136/bjsports-2016-097071
“Low-load exercise training with blood flow restriction (BFR) can increase muscle strength and may offer an effective clinical musculoskeletal (MSK) rehabilitation tool. The aim of this review was to systematically analyse the evidence regarding the effectiveness of this novel training modality in clinical MSK rehabilitation.” —Ver artículo en PDF.
LOW INTENSITY SPRINT TRAINING WITH BLOOD FLOW RESTRICTION IMPROVES 100 M DASH
Journal of Strength and Conditioning Research Publish Ahead of Print DOI: 10.1519/JSC.0000000000001746.
“We investigated the effects of practical blood flow restriction (pBFR) of leg muscles during sprint training on the 100 m dash time in well-trained sport students. Methods: Participants performed 6×100 m sprints at 60-70% of their maximal 100 m sprinting speed twice a week for 6 weeks, either with (IG; n=12) or without pBFR (CG; n=12). Results: The 100 m dash time significantly decreased more in the IG (-0.38±0.24 s) than in the CG (-0.16±0.17 s).” —Ver artículo en PDF.
EFFECTS OF RESISTANCE EXERCISE COMBINED WITH MODERATE VASCULAR OCCLUSION ON MUSCULAR FUNCTION IN HUMANS.

“Effects of resistance exercise combined with moderate vascular occlusion on muscular function in humans. J Appl Physiol 88: 2097–2106, 2000.—Acute and long-term effects of resistance exercise combined with vascular occlusion on muscular function were investigated. Changes in integrated electromyogram with respect to time (iEMG), vascular resistive index, and plasma lactate concentration were measured in five men either during or after elbow flexion exercises with the proximal end of the arm occluded at 0–100 mmHg.” —Ver artículo en PDF.
HEMODYNAMIC AND HORMONAL RESPONSES TO A SHORT-TERM LOW-INTENSITY RESISTANCE EXERCISE WITH THE REDUCTION OF MUSCLE BLOOD FLOW.
Arbeitsphysiologie · October 2005
“We investigated the hemodynamic and hormonal responses to a short-term low-intensity resistance exercise (STLIRE) with the reduction of muscle blood flow. Eleven untrained men performed bilateral leg extension exercise under the reduction of muscle blood flow of the proximal end of both legs pressure-applied by a specially designed belt (a banding pressure of 1.3 times higher than resting systolic blood pressure, 160–180 mmHg), named as Kaatsu. The intensity of STL-IRE was 20% of one repetition maximum. The subjects performed 30 repetitions, and after a 20-seconds rest, they performed three sets again until exhaustion.” —Ver artículo en PDF.
BLOOD FLOW RESTRICTION WALKING AND PHYSICAL FUNCTION IN OLDER ADULTS: A RANDOMIZED CONTROL TRIAL.
Journal of Science and Medicine in Sport April 2017
“The progressive age-related declines in muscle health and physical function in older adults are related to muscle size and strength. Walking with an applied blood flow restriction is an alternative to maintain muscle volume in older adults to increase the value for time spent walking. Therefore, the aim of this study was to examine the effect of adding blood flow restriction to low-intensity walking on clinical measures of physical function.” —Ver artículo en PDF.
THE EFFECTS OF PRACTICAL BLOOD FLOW RESTRICTION TRAINING ON ADOLESCENT LOWER BODY STRENGTH.
Journal of Strength and Conditioning Research Publish Ahead of Print DOI: 10.1519/JSC.0000000000002302
“The purpose of this study was to examine the effects of a practical blood flow restriction (BFR) training program on lower-body strength of high school weightlifters. Twenty-five students were divided into three groups. For six weeks, each group completed the same resistance training program with the exception of the parallel back squat exercise (2 days/week), which was different for each group. One group (HI) completed a traditional high load (≥65% 1RM) back TE squat protocol with three sets of low repetitions (≤10).” —Ver artículo en PDF.
IMPACT OF BLOOD FLOW RESTRICTION EXERCISE ON MUSCLE FATIGUE DEVELOPMENT AND RECOVERY.
Institute of Sport Science, University of Rostock, Germany; Department of Traumatology, Hand and Reconstructive Surgery, University Medicine Rostock, Germany
“The present study was designed to provide mechanistic insight into the time-course and etiology of muscle fatigue development and recovery during and after low-intensity exercise when it is combined with blood flow restriction (BFR). Methods: Seventeen resistance-trained males completed four sets of low-intensity isotonic resistance exercise under two experimental conditions: knee extension exercise combined with (i) BFR and (ii) without BFR (CON). Neuromuscular tests were performed before, during (immediately after each set of knee extension exercise) and 1, 2, 4, and 8 min after each experimental condition.” —Ver artículo en PDF.
RAPID INCREASE IN PLASMA GROWTH HORMONE AFTER LOW‐INTENSITY RESISTANCE EXERCISE WITH VASCULAR OCCLUSION.
Yokohama Sports Medical Center; Institute of Sports Medical Science, Tokai University; DepartTnent Of Life Sciences, College of Arts and Sciences, University of Tokyo
“Rapid increase in plasma growth hormone after low‐intensity resistance exercise with vascular occlusion. J. Appl. Physiol. 88: 61‐65, 2000.‐Hormonaland inflammatory responses to low‐intensity resistance exercise with vascular occlusion were studied. Subjects (n ‐ 6) perfomed bilateral leg extension exercise in the seated position, with the proximal end of their thigh compresSed at 214 ± 7.7 (SE) mmHg throughout the session of exercise by means of a pressure tourniquet. Mean intensity and quantity of the exercise were 20% of 1 repetition maximum and 14 repetitions x 5 sets, respectively. In each set, the subjects repeatedthe movementuntil exhaustion.” —Ver artículo en PDF.
