Technique of Restriction of Blood Flow Associated With the Ergonomic Cycle of Upper Limbs in Women (Kaatsu-BFR)
Technique of Restriction of Blood Flow Associated With the Ergonomic Cycle of Upper Limbs in Women. A Randomized Pilot Study
Finding alternatives to improve variables such as strength and anaerobic resistance is a subject of highly studied clinical intervention. The use of vascular occlusion associated with physical exercise has shown efficacy in improving these aspects.
The objective is to analyze the effectiveness of upper limb training with vascular occlusion (Kaatsu training) for the improvement of isometric strength and anaerobic capacity in women aged 18 to 38 years.
Study design. Randomized, prospective, single-blind, follow-up clinical study. The selected sample will be randomized into two groups: experimental and control. The intervention will consist of ergonomic exercises with and without vascular occlusion. Isometric strength will be assessed with a manual dynamometer, anaerobic capacity and peak power (anaerobic alactic system) and average power (anaerobic lactic system) with the wingate test, and subjective perception of effort with the Borg scale. The intervention will last 4 weeks, with 3 weekly sessions of 10 minutes each. A descriptive statistical analysis will be carried out among the dependent and independent variables of both groups. With the Kolmogórov distribution normality test and with the Anova and t-student tests for analysis of repeated measures.
Expected results. The investigators intend to observe improvement of isometric biceps and triceps strength and the anaerobic capacity of the group treated with vascular occlusion.

Intervention / Treatment |
---|---|
Experimental: Experimental group
The intervention lasted 17 minutes each session, 2 weekly sessions were carried out, during 4 weeks. The training started with a warm-up on the hand bike without a load for 5 minutes. Later, we did a work of 3 series of 30 seconds, in maximum power, with 5 minutes of rest between them. The intensity was calculated by 0.048 kp.kg. The subjects of the experimental group made use of the restriction of blood flow, using a pressure cuff coupled in the most proximal region of the arm, 10 cm wide. The pressure was calculated based on the initial systolic pressure of the subjects. |

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change from baseline isometric strength of biceps after treatment and at 1 month
Time Frame: Screening visit, within the first seven days after treatment and after one month follow-up visit]
|
A Lafayette Manual Muscle Testing System force dynamometer (model 01165, USA) was used.
The subject was standing with the trunk straight, the shoulders in neutral position with the arms aligned to the trunk and the elbows in 90 degrees of flexion.
The evaluator requested a maximum voluntary isometric muscle contraction in elbow flexion, maintaining it for 5 seconds.
Three repetitions were performed, with 5 minutes of rest between each series, the reference value being the average of the value obtained between the 3 repetitions.

Time Frame: Screening visit, within the first seven days after treatment and after one month follow-up visit
|
The WinGate test was used.
The equipment used was an ergonomic clico for upper limbs (Excite® top seat, technogyn, Brazil).
Each subject was placed seated, so that the center of the glenohumeral joint was aligned with the axis of the cranks of the equipment, with 90 degrees of knee flexion, which were aligned with shoulders and feet.
The horizontal distance was adjusted so that the elbows were not in maximum extension and allowing the comfort of the participants.
