ABSTRACT
[Object and Subjects] We studied the effects of both electrical and massage (frictional) stimulation on the dorsal region (e.g. BL 13, BL21 and BL23) in experimental dietary obese rats for three weeks as a simple obesity model.<BR>[Results] The electrical and massage (frictional) groups showed reduced (p<0.01) body weight compared with non-treated obese rats, the control group. The electrical stimulation group decreased in body weight more than the massage (frictional) stimulation group. Food intake per 100 g of body weight did not differ between the three groups. There was no significant difference in leptin concentration in the blood pre-and poststimulus, but a tendency for it to decrease was seen in the stimulus groups (p=0.074). This might be diagnosed as normalized hyper-leptinemia and /or leptin-resistance.<BR>These results suggest the existence of action mechanisms for weight decrease originating in electrical and mas-sage (frictional) stimulation, which obviously is different from the case of “the auricular acupuncture stimulus”.<BR>[Conclusion] In conclusion, the possibility of a new application of the “ANMA·massage·SHIATSU” treatment was apparent from this result.
ABSTRACT
The purpose of this study was to examine the relation between body composition and athletic performance of long distance relay runners in a four week weight reduction program. Six male collegiate runners, aged 19.0 ± 0.9 years, participated in this study. Body water content and fat free mass (FFM) were measured by bioelectrical impedance spectroscopy.The weight loss by 4.1% of the initial body weight consisted of decreases in FFM and fat mass (54% and 46% respectively). Percentage of body fat did not change significantly by the end of the fourth week. The total body water (TBW) loss comprised of intracellular water (ICW) and extracellular water (ECW) at the end of the fourth week, and TBW loss and FFM loss were nearly the same values. Isokinetic muscular strength of right thigh, maximal oxygen intake (VO<sub>2</sub>max) and total treadmill running time (maximal workout time) measured did not show any significant change. These results indicate (1) half of the weight loss consisted of decrease in FFM, (2) TBW loss was due to the reduction of ICW and ECW, (3) the content of FFM loss was considered to be body water, and (4) there was no impact on muscular strength of right thigh, VO<sub>2</sub>max or maximal workout time.
