Methods: Thirty healthy adults (24.1 ± 2.0 years) with normal occlusion performed gum chewing exercise 3 times daily for 3 months. Each exercise session lasted 5 min and involved alternating of chewing 10 times using the left molars and then 10 times using the right molars, with the mouth closed. The effect of the exercise on oral function was evaluated by measuring tongue pressure (TP), cheek pressure (CP), and labial closure strength (LCS) immediately before starting exercise, at 2 weeks and 1, 2, and 3 months after starting exercise, and at 3 months after cessation of exercise. Changes in TP, CP, and LCS according to sex and duration of exercise were analyzed by repeated two-way ANOVA. Results: Measurements for all muscles were significantly greater in men than in women at all time points. After starting exercise, TP was markedly increased at 2 months in men and women, and both CP and LCS were markedly increased at 2 weeks in men and at 1 month in women. These effects persisted for 3 months. Three months after cessation of exercise, TP, CP, and LCS tended to decrease, but were not significantly attenuated as compared with 3 months after beginning of exercise in either sex. Conclusion: The results of this study revealed that gum chewing exercise contributed to an improvement in perioral muscle strength, and that this effect was maintained for at least 3 months after discontinuation of exercise.展开更多

Healthy male subjects who have no habit of resistance training underwent resistance exercise (chest press, lat pulldown, leg press, shoulder press, leg extension, and leg curl), with 3 sets of each exercise and 10 repetitions in each set at 90-s intervals, 30 min after ingestion of ornithine or placebo. Plasma ornithine levels immediately after, and 120 and 180 min after, resistance exercise were significantly greater after ingestion of ornithine than of placebo (Treatment: F = 347.1, P p2 = 0.95;Interaction: F = 160.7, P p2 = 0.95), but no significant difference in serum growth hormone levels was observed between the two treatments (Treatment: F = 0.1, P = 0.751, ηp2 = 0.01;Time: F = 1.7, P = 0.229, ηp2 = 0.16;Interaction: F = 2.4, P = 0.155, ηp2 = 0.21). Although there was no between-treatment difference in energy expenditure during the rest period 120 to 180 min after resistance exercise (Treatment: F = 0.1, P = 0.718, ηp2 = 0.02;Time: F = 0.1, P = 0.767, ηp2 = 0.01;Interaction: F = 0.1, P = 0.112, ηp2 = 0.26), with ornithine ingestion carbohydrate oxidation was significantly greater than with placebo from 170 to 180 min after exercise (Treatment: F = 0.8, P = 0.383, ηp2 = 0.09;Time: F = 9.7, P = 0.013, ηp2 = 0.52;Interaction: F = 5.8, P = 0.039, ηp2 = 0.39). Moreover, 180 min after exercise, serum free fatty acid levels after ornithine ingestion were lower than after placebo (Treatment: F = 0.3, P = 0.602, ηp2 = 0.03;Time: F = 34.6, P p2 = 0.79;Interaction: F = 5.6, P = 0.042, ηp2 = 0.38). A similar trend in 3-hydroxybutylate was observed. In conclusion, ornithine ingestion before resistance exercise may enhance post-exercise carbohydrate oxidation without changing total energy expenditure.展开更多

However, this is a comparatively recent development. This paper begins with an historical overview outlining the origins of the communicative approach in Europe and the United States and noting that they arrived at a consensus for entirely different historical reasons. In China English replaced Russian as the most important foreign language a generation ago but even then the emphasis was on receptive skills. The thorny question of authenticity is then discussed. While everyone agrees that in theory authenticity is a key consideration there is considerably less agreement on how to convert theory into practice. Finally the paper goes on to note how recent practice has abandoned the teacher-centered approach in favor of the learner-centered approach and the exercise-based approach in favor of the task-based approach, The task-based approach emphasizes integrated as opposed to individual skills acquisition.
