Overweight or obesity becomes a worldwide public health issue; the global obesity pandemic. Strategies to effectively prevent overweight and obesity are needed. Slow eating, which involves chewing food slowly and thoroughly, can be an effective strategy to prevent overweight and obesity. Previous studies reported a relationship between rapid eating and overweight. Candidate factors inducing the relationship have been thought to be related to increases in appetite and energy intake through rapid eating, allowing the ingestion of a greater-than-optimal volume of food. While the counter effect of slow eating has been widely known, effects of eating speed on digestion, absorption, and metabolism has yet to be elucidated. If eating speed affects digestion, absorption, and metabolism, eating speed can be a factor explaining the relationship between eating speed and body composition. The present review is to summarize the effects of eating speed on digestion, absorption, and metabolism, consequently suggesting preferable effects of slowly eating on increasing energy expenditure after eating.

To investigate the effect of resistance training at lower than the recommended frequency (2–3 times a week) on muscular strength, we recruited 103 college students (67 males 61±8 kg, 36 females 51±4 kg, mean±SD) who had never regularly engaged in resistance training. They performed resistance training in a PE class once a week for seven to ten weeks. We measured one repetition maximum (1 RM) for the bench press and arm curl, and the girth of the thigh and upper arm before and after the training. The training included stretching, three sets of ten repetitions on a bench press, half squat lift, arm curl and three types of training chosen by each subject. The weight load was 10 RM, which was progressively increased; when the subject succeeded in lifting a load ten times at the first set, the load was increased in the following week. After the training period 1RM was increased by more than 10% compared with that before training, for either the bench press or the arm curl, in all subjects. The 1 RM for the bench press significantly increased from 46±9 kg to 54±9 kg in males, and from 22±4 kg to 28±5 kg in females, and that for the arm curl also increased significantly. No significant change was found in the girth of the thigh and upper arm. On the other hand, 49 male students who undertook softball in a PE class did not show any significant change in 1 RM after the eight-week control period, compared to that before the period. These results demonstrate that resistance training at a frequency lower than the recommended one increases muscular strength in college students, possibly through adaptations in the nervous system.

昼食後の眠気による作業効率低下対策として知られている短時間仮眠が,その後の運動パフォーマンスやそれを支える基礎的な生理機能に与える効果について,包括的かつ実践的な検討を行った。結果として,1)昼食後に睡眠ステージ2までの浅い短時間仮眠(napと呼ばれ,10-20分程度)をとると,覚醒したまま安静で過ごすよりも,スポーツ競技時に必要と想定される脳の情報処理能力や視力に正の効果がありそうであること,2)昼食後に睡眠ステージ4まで含む1時間程度のより深い仮眠をとると,安静やnapをとる過ごし方よりも,無酸素性最大発揮パワーに正の効果がありそうであること,の2点が示唆された。

A study was conducted to investigate the effect of exercise intensity on the recovery of autonomic nervous activity after exercise. Ten subjects performed four kinds of 10-min cycle exercise with target heart rates of 100, 120, 140, and 160 beats/min (THR 100, THR 120, THR 140 and THR 160, respectively) following 5 min of exercise to increase the heart rate to the target level. The beat-by-beat variability of the R-R interval was recorded throughout the experiment including the 5-min pre-exercise control period and the 30-min recovery period. Spectral analysis (fast Fourier transform) was applied to every 5-min R-R interval data set before, during ( 5-10 min) and after exercise at the target heart rate. The low- (0.05-0, 15 Hz : P1) and high- (0, 15-1.0 Hz : Ph) frequency areas were calculated to evaluate sympathetic (SNS) and parasympathetic (PNS) nervous activities as P1/Phand Ph, respectively. During exercise, SNS of THR 160 was significantly higher, and PNS of THR 140 and THR 160 was significantly lower than the respective pre-exercise values (p<0.05) . Althouglt all indicators recovered to, or overshot the pre-exercise values at 20-30 min after THR 100 and THR 120, heart rate and SNS were still higher and PNS was still lower than the pre-exercise value after THR 160. These results suggest that the recovery of cardiac autonomic nervous activity is slower after high-intensity exercise than after low-intensity exercise, and that the recovery of autonomic nervous activity after acute exercise does not always corrrespond linearly on the exercise intensity.
