Subjective symptoms of Internet addiction (IA), such as interpersonal and health-related problems (IH-RP), do not correlate with objective physiological parameters. This study aimed to investigate the cardiovascular reactivity after physical exercise in 15-16-year-old adolescents showing different severities of symptoms of health-related problems due to Internet overuse.
This study included 20 healthy adolescents (boys, 15-16 years) with different risks of IA (by the Chen internet addiction scale [CIAS]). The physical exercise test was to perform a standing broad jump three times. The arterial blood pressures and heart rates were recorded before, immediately after, and at 4 minutes of rest after exercise.
The total sample of adolescents was divided into two groups, that is, those with IH-RP scores of 12 or less (Group I, n = 12) and those scoring more than 12 points (Group II, n = 8). The diastolic blood pressure significantly increased after exercise in group II, whereas it remained stable in group I. The heart rate in group I tended to increase, but the changes were not statistically significant. Group II adolescents showed significant increases in heart rate, and at rest, this parameter was significantly higher than the baseline value.
Adolescents with a risk of IA and severe symptoms of interpersonal and health-related problems had increased sympathetic activity during and after speed-strength physical exercise compared to those without the aforementioned symptoms.
网络成瘾（IA）的主观症状，如人际关系和健康相关问题（IH-RP），与客观的生理参数无关。本研究旨在调查 15-16 岁青少年在过度上网导致不同严重程度健康相关问题症状后进行身体锻炼时的心血管反应。
本研究包括 20 名健康青少年（男孩，15-16 岁），具有不同的 IA 风险（根据 Chen 互联网成瘾量表[CIAS]）。身体锻炼测试是进行三次立定跳远。在运动前、运动后立即和运动后 4 分钟休息时记录动脉血压和心率。
青少年总样本分为两组，即 IH-RP 评分在 12 分或以下的组（I 组，n = 12）和评分超过 12 分的组（II 组，n = 8）。运动后，II 组的舒张压显著升高，而 I 组则保持稳定。I 组的心率有升高的趋势，但变化无统计学意义。II 组青少年的心率明显增加，休息时，该参数明显高于基线值。
与无上述症状的青少年相比，有 IA 风险和严重人际关系及健康相关问题症状的青少年在速度力量型身体锻炼期间和之后表现出更高的交感神经活动。
