| 概要 |
The purpose of this study is to investigate the antiobestic effect of NESS system, a computerized counseling system for prescription of nutrition and exercise, in which subjects were asked to adopt ho...me-delivered dietary menus for calorie intake restriction and to consume a certain amount of energy by sustained daily routine exercise in an attempt to approach the ideal body fat content. Before the experiment, female students were screened for body composition and physical fitness. Slightly obese subjects were divided into two groups : those with the % body fat (measured by the bioelectrical impedance method) equal to or above 22.0% (prescription group [PG], n =9) and those with less than 22.0% (control group[CG]，n =3). The PG were allowed to take in 14OOkcal in the form of home-delivered breakfast and supper and ad-lib lunch, and were assigned an exercise menu to consume 300kcal daily for a period of 56 days. It is showed that both groups decrese body weight, but the decrese of only the PG was significant. The body weight decrese was mainly ascribable to a decrese in body fat content in the PG and in lean body mass (LBM) in the CG. The body weight of the PG was decresed to the range of ±7% of the target ideal value of the NESS system. As for the body composition and physical fitness of the PG, changes in waist-to-hip ratio (WHR) were observed and so was significant improvement in the tests of sit and reach and sit-up and VO2max. These results indicated that restriction of calorie intake by the delivery system could be easily carried out under good control and was effective in reducing the body weight. Thus, the diet and exercise therapy is expected to not only lower the body fat content but also improve endurance capacity, In conclusion, the regimen in the NESS system is an appropriate measure for treatment of obesity.
本研究は，NESSシステム（コンピューターを用いだ栄養と運動のカウンセリングシステム）を用いて食事では摂取エネルギーを制限した宅配方式のメニューを採用し，エネルギーを消費するために日常行えるような運動を継続させることにより，体脂肪のみを理想値に近づけると同時に肥満治療効果を検討することであった。実験前後に形態，体力測定を行い，やや肥満な女子学生を体脂肪率（インピーダンス法）をもとに，22.0％以上を処方群（n=9）とそれ未満を対照群（ｎ=3）の2群に分けた。処方群の摂取エネルギー量は1400kcalを目安にし，朝食および夕食は宅配方式とし，昼食は自由に摂取させた。運動は1日300kcalを消費させる処方を56日間実施した。体重減少について両群とも減少したが，処方群においてのみ有意な減少が認められた。また処方群は主に体脂肪が減少したが，対照群ではLBMの減少によるものであった。処方群ではNESSシステムの示す理想値の±7%の範囲で体重が減少した。処方群において形態ではWHRの変化がみられ，また体力面では長座体前屈，上体起こし, VO2maxなどが有意に向上した。以上の結果から，宅配方式による摂取エネルギーの制限は管理が容易で体重減少の点では有効であった。また十分な管理下での食事，運動療法を行うと主に体脂肪が減少するだけでなく，持久力の向上も期待できる。したがって，NESSシステムによる処方が妥当であると結論された。続きを見る
