The aim of this study was to determine the acute effects of exercise intensity on anxiety, mood states and hunger in obese adolescents.
Subjects were eight male obese adolescents (age 15.44 ± 2.06 y; BMI 33.06 ± 4.78 kg/m2). Each subject underwent three experimental trials: (1) Control, seated for 30 min; (2) Low intensity exercise (LIE)--exercise at 10% below ventilatory threshold (VT); (3) High intensity exercise (HIE)--exercise at 10% above VT. Anxiety (STAI Trait/State), mood (POMS) and hunger (VAS) were assessed before and immediately after the experimental sessions. Comparisons between trials and times were assessed using Kruskal-Wallis and Wilcoxon tests, respectively. Associations between variables were described using a Spearman test.
The largest increase in hunger was observed after LEI (914.22%). Both exercise sessions increased anxiety, fatigue and decreased vigor (p < 0.05).
Acute exercise bouts are associated with negative changes in anxiety and mood, and with increases in hunger in obese adolescents.
本研究的目的是确定运动强度对肥胖青少年焦虑、情绪状态和饥饿感的急性影响。
受试者为八名男性肥胖青少年（年龄15.44 ± 2.06岁；体重指数33.06 ± 4.78kg/m²）。每位受试者进行三项实验性试验：（1）对照组，静坐30分钟；（2）低强度运动（LIE）——在低于通气阈值（VT）10%的强度下运动；（3）高强度运动（HIE）——在高于VT 10%的强度下运动。在实验环节前后分别评估焦虑（状态-特质焦虑量表）、情绪（情绪状态量表）和饥饿感（视觉模拟量表）。分别使用克鲁斯卡尔-沃利斯检验和威尔科克森检验评估试验之间和不同时间点之间的差异。使用斯皮尔曼检验描述变量之间的关联。
低强度运动后饥饿感增加幅度最大（914.22%）。两次运动均增加了焦虑、疲劳感，并降低了活力（p < 0.05）。
急性运动发作与肥胖青少年焦虑和情绪的负面变化以及饥饿感增加有关。
