“…Also, the deterioration of ischemic heart disease has been described in rare cases (2 cases). The conceivable reason is as follows; Application of KAATSU training on both legs caused the pooling of venous blood with the pressure-dependent reduction of femoral arterial blood flow (Iida et al, 2005). The inhibition of venous return during the KAATSU exercise reduces cardiac preload during the exercise, which may be beneficial in rehabilitation of certain patients with cardiac diseases (Takano et al, 2005a, b).…”

“…Therefore, we are concerned about the formation of thrombus, muscle damage, and the occurrence of pulmonary embolism in the subjects, when KAATSU training is applied. In addition, although KAATSU training restricts venous flow, induces the pooling of venous blood, and subsequently reduces cardiac preload during exercise, which may be useful in rehabilitation in patients with cardiac diseases (Takano et al, 2005a, b;Iida et al, 2005), the excessive inhibition of cardiac preload may decrease cardiac output, and thereafter blood flow to the brain and coronary circulation. Consequently, side effects such as dizziness, fainting, cerebral anemia and the deterioration of ischemic heart disease may occur.…”

KAATSU training is a novel training, which is performed under conditions of restricted blood flow. It can induce a variety of beneficial effects such as increased muscle strength, and it has been adopted by a number of facilities in recent times. The purpose of the present study is to know the present state of KAATSU training in Japan and examine the incidence of adverse events in the field. The data were obtained from KAATSU leaders or instructors in a total of 105 out of 195 facilities where KAATSU training has been adopted. Based on survey results, 12,642 persons have received KAATSU training (male 45.4%, female 54.6%). KAATSU training has been applied to all generations of people including the young (<20 years old) and the elderly (>80 years old). The most popular purpose of KAATSU training is to strengthen muscle in athletes and to promote the health of subjects, including the elderly. It has been also applied to various kinds of physical conditions, cerebrovascular diseases, orthopedic diseases, obesity, cardiac diseases, neuromuscular diseases, diabetes, hypertension and respiratory diseases. In KAATSU training, various types of exercise modalities (physical exercise, walking, cycling, and weight training) are used. Most facilities have used 5-30 min KAATSU training each time, and performed it 1-3 times a week. Approximately 80% of the facilities are satisfied with the results of KAATSU training with only small numbers of complications reported. The incidence of side effects was as follows; venous thrombus (0.055%), pulmonary embolism (0.008%) and rhabdomyolysis (0.008%). These results indicate that the KAATSU training is a safe and promising method for training athletes and healthy persons, and can also be applied to persons with various physical conditions.

“…One is mainly due to a quick recovery from the vagal hypertonus. Iida et al (2005) reported a high frequency of RR variability (HFRR), a marker of the parasympathetic activity, decreased after Kaatsu in both legs, while LFRR/HFRR, a quantitative marker of sympathetic nerve activity, increased in men. It is unclear whether Kaatsu can keep maintain such acute effects for a long term.…”

“…It consists of lowintensity resistance training (20%~30% of 1RM) with a restriction of the venous return using a specially designed belt while applying pressure at the proximal end of the upper or lower extremities. This revolutionary method has been established not only to build up the body (Takarada et al, 2000;Abe et al,2005) but also to recover from bone fractures (Sato, 2005), patella tendonitis (Sata, 2005), and for rehabilitation from cerebral palsy (Odagiri, 2004), heart disease (Nakajima, 2005), a low physical fitness level (Takano et al, 2005) and for the overall improvement of frail elderly individuals (Ishii, 2005). The supersecretion of bioactive substances such as growth hormone (GH) (Takarada et al, 2000) and insulin-like growth factor-1 (IGF-1) greatly contributes to the mechanism of increasing the muscle size and power.…”

ARTIGO ORIGINAL | ORIGINAL ARTICLE RESUMOO objetivo do presente estudo foi verificar o efeito agudo do exercício predominantemente aeróbico (EA) com restrição de fluxo sanguíneo (RFS) sobre a pressão arterial sistólica (PAS), pressão arterial diastólica (PAD) e frequência cardíaca (FC) em jovens saudáveis. Participaram do estudo 13 universitários normotensos (19.5 ± 1.7anos). Os participantes foram divididos randomicamente em duas sessões experimentais (cross-over): a) exercício aeróbico com a RFS (EARFS); b) exercício aeróbico sem a RFS (EASRFS). As sessões foram realizadas com cinco séries de dois minutos e um minuto de intervalo. A PAS, PAD e FC foram mensurados em repouso, no final dos exercícios e durante os 60 minutos pós-exercício. O EASRFS apresentou efeito hipotensivo no 60º pós-exercício (p= 0.029); o EA com e sem RFS elevou significativamente a PAS e FC imediatamente após o exercício (p< 0.05), e o EARFS apresentou valores de PAD e FC superiores, no momento imediatamente pós-exercício, quando comparado com o EASRFS (p= 0.001; p< 0.001, respectivamente). Conclui-se, que o EARFS parece não maximizar o efeito hipotensivo, ambos as sessões podem elevar a PAS e FC imediatamente pós-exercício com valores significativos maiores na PAD e FC para o EARFS. Palavras-chave: hemodinâmica, oclusão vascular, exercício, efeito hipotensivo. ABSTRACTThe aim of the present study was to verify the acute effect of the aerobic exercise (AE) with blood flow restriction (BFR) upon systolic (SBP), diastolic blood pressure (DBP) and heart rate (HR) in health youngsters. Participated in the present study 13 young normotensive students (19.5 ± 1.7 years old). The sample was randomly divided into two experimental protocols: stationary race with BFR and stationary race without BFR. Subjects performed 5 sets of 2 minutes with 1 minute of rest interval for both protocols. SBP, DBP and HR were measured at rest, in the end of the exercises and during 60 minutes after conditions. The AE without BFR presented hypotensive effect 60 minutes post exercise (p= 0.029); the AE with and without BFR elevated significantly the SBP and HR immediately post exercise (p< 0.05) and the AE with BFR presented higher DBP and HR values immediately post-exercise when compared to AE without BFR (p= 0.001; p< 0.001, respectively). It is concluded that the AE without BFR does not seem to maximize the hypotensive effect, both sessions can increase SBP and HR immediately post-exercise with significant higher values in DBP and HR for AE with BFR.
