The purpose of this study was to investigate once-daily walk training with restricted leg blood flow (KAATSU) on thigh muscle size and strength. Twelve young men performed walk training: KAATSU-walk training (n=6) and control (no KAATSU-walk; n=6). Training was conducted once daily, 6 days per week, for 3 weeks. Treadmill walking (50 m/min) was performed for 5 sets of 2-min bouts interspersed with 1-min rest periods. The KAATSU-walk group wore pressure cuff belts (5 cm wide) on both legs during ...

The present study developed nonexercise models for predicting maximal oxygen uptake \(({\dot{{V}}}\hbox{O}_{\rm{2max}})\) using skeletal muscle (SM) mass and cardiac dimensions and to investigate the validity of these equations in healthy Japanese young men. Sixty healthy Japanese men were randomly separated into two groups: 40 in the development group and 20 in the validation group. \({\dot{{V}}}\hbox{O}_{\rm{2max}}\) during treadmill running was measured using an automated breath-by-breath mas...

Previous studies have shown that low-intensity resistance training with restricted muscular venous blood flow (Kaatsu) causes muscle hypertrophy and strength gain. To investigate the effects of daily physical activity combined with Kaatsu, we examined the acute and chronic effects of walk training with and without Kaatsu on MRI-measured muscle size and maximum dynamic (one repetition maximum) and isometric strength, along with blood hormonal parameters. Nine men performed Kaatsu-walk training, a...

Introduction: Adipose tissue plays complex role(s) in metabolic and endocrine control. To date, little work has been done in the horse regarding adipocytokines. Purpose: This study was conducted to determine whether therapeutic levels of chronic [beta]-agonist administration, exercise, or both could alter their concentrations. Methods: A total of 23 standard-bred mares were divided into four experimental groups: clenbuterol (2.4 [mu]g[middle dot]kg-1 bw twice daily for 8 wk) plus exercise (8 wk,...

In order to produce significant muscle hypertrophy, a training intensity of greater than 65% of the 1-repetition maximum (1-RM) is generally believed to be required. However, this concept has been challenged recently by data from studies that have combined 20%-50% 1-RM with restriction of venous blood flow from the working muscle, referred to as KAATSU-training. These studies have demonstrated significant gains in muscle size and strength in as little as 2 weeks in humans. The KAATSU-training mo...

The present study was performed to develop regression-based prediction equations for skeletal muscle (SM) mass by ultrasound and to investigate the validity of these equations in Japanese adults. Seventy-two Japanese men (n=38) and women (n=34) aged 18–61 years participated in this study and were randomly separated into two groups: the model development group (n=48) and the validation group (n=24). The total and regional SM mass were measured using magnetic resonance imaging (MRI) 1.5 T-scanners...
