ウォーキングスピードの違いとエネルギー代謝の関連について検討した.対象者は, 健康な中年女性7名 (35~50歳) であり, 3種類のスピード (経済: 1km当りのエネルギー消費量が最小となるスピード, 快適: 被験者が気持ちよいと答えたスピード, 速歩: 被験者が無理のない範囲で最も速く歩けると答えたスピード) での60分間のトレッドミルウォーキングを課して代謝反応と血中脂質を測定し, 次のような結果を得た.<BR>1) 60分間のトレッドミルウォーキングを実施したスピードとそれぞれのスピードにおける%VO<SUB>2</SUB>maxと心拍数は, 経済が76m/min (41%VO<SUB>2</SUB>max, 96beats/min) , 快適で90m/min (49%VO<SUB>2</SUB>max, 110beats/min) , 速歩は106m/min (67%VO<SUB>2</SUB>max, 139beats/min) であった.<BR>2) 5分ごとに見た脂肪によるエネルギー消費量は, 3スピードとも経時的に増加したが, 特に速歩スピードでは, 運動開始後の10分目で1.1kcal/minであった脂肪によるエネルギー消費量が運動終了時には2.5kcal/minと2倍以上に達した.<BR>3) 60分間ウォーキングでの総エネルギー消費量はスピードに伴い増加した.脂肪によるエネルギー消費量は, 速歩が109kcalで最も高い値を示したが, 快適: 99kcal, 経済: 92kcalとの間に有意差は認められなかった.

The purpose of this study was to evaluate the change in dynamic and static balance ability during the menstrual cycle among young women. The subjects were young healthy women (n = 12, age 20.4 ± 1.2 years) with regular exercise and a normal menstrual cycle. The menstrual cycle was divided into 5 phases : Menstrual, Follicular, Ovulatory, Early luteal and Late luteal. Measurements were taken using the dynamic balance test, static balance test and looseness test. The dynamic balance test did not change during the menstrual cycle. Length/Time within the static balance test increased in the late luteal phase compared to other menstrual cycle phases. The deviation of the mean of X within the static balance test increased in the follicular and late luteal phase and decreased in the ovulatory phase. Also, the deviation of the mean of X increased in the follicular phase compared to the menstrual phase and decreased in the menstrual and early luteal phases compared to the follicular and ovulatory. Left arm upper of laxity in hand on the back test within looseness test increased in the menstrual and early luteal phases compared to other menstrual cycle phases. These results suggest that static balance ability changes during the menstrual cycle.

Amplitude and phase response of ventilation (V_E), carbon dioxide output (VCO_2) and oxygen uptake (VO_2) during sinusoidally varying work load for periods (T) of 1〜16 min were studied in six healthy men. The relationships between these parameters and aerobic capacity (VO_2max, ATVO_2) were also examined.The results and conclusions obtained were as follows : (1)The relationship between the period (T) of exercise and amplitude response of VO_2,VCO_2 and V_E was well described by first-order exponential models.However,the relationship between the period of exercise and the phase shift (phase responses of VO_2,VCO_2,and V_E) was better described by complex models comprising a first-order exponential function and a linear equation.This can be explained by Karpman's threshold theory.(2)High negative correlations were observed between the steady-state amplitude (A) of phase response or the time constants (〓) of amplitude response and VO_2max,and ATVO_2.Significantly high negative correlations for all gas exchange parameters may be more rapid in individuals with greater aerobic capacity.(3)A close relationship between the response of VCO_2 and V_E was demonstrated by a higher correlation coefficient than that between VO_2 and VCO_2 or between VO_2 and V_E.This call be partly,but not completely,explained by the cardiodynamic theory.
