Women's Health: Female Athlete/Female Athlete Triad Clinical Trial
Official title:
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.
The use of peripheral vascular occlusion in low intensity resistance exercises is a simple, safe and effective method, indicated for healthy individuals or with cardio-respiratory diseases, in the prevention of atrophy due to disuse, within the post rehabilitation approach. -surgical intervention and to improve the performance of athletes. Several studies evaluated the use of blood flow restriction prior to aerobic and anaerobic exercises, with heterogeneous results, without consensus. With this, our research proposal is a pioneer, as there is no other study that has investigated the use of upper limb vascular occlusion during anaerobic activity in an arm ergometer cycle. This could benefit individuals who need to maintain their anaerobic conditioning and who, for some reason, are unable to use the lower limbs. In addition, it could benefit in the performance and improvement of the physical fitness of athletes in wheelchairs of various modalities, which have their functions preserved in the upper limbs. Only a similar study showed the efficacy of this intervention model, but in lower limbs. The prevalence of men in published studies of anaerobic capacity with the WinGate test, with few studies recruiting women, indicates the need to perform the study with a female sample. ;
