To examine the associations of cardiorespiratory fitness (VO max) and muscular strength with indicators related to the risk scale, such as perceived competence, sensation seeking, competitiveness, risk taking and risk perception in sports.
Cross-sectional study.
High schools from the Region of Murcia (Spain).
Three-hundred-and-seventeen adolescents participated (mean age: 13.69±1.2 years old).
Body mass, body height, Course-Navette test, upper limb strength and psychoeducational factors that determine the propensity towards sports accidents in school children, the Sports Accident Propensity Scale were evaluated. It was performance t-test for independent samples, stepwise multiple linear regression models and a multiple mediation analysis.
The analysis showed significant differences with respect to sex in height, VO max, handgrip strength and in all factors of the questionnaire (p=0.02-<0.01). Adolescents who presented greater VO max, strength in the handgrip test and age showed a higher score in factors 1 and 3. Higher scores in factor 2 were associated with better VO max and strength in handgrip test. Youngers and better values of strength in the handgrip showed higher score in factors 4 and 5. The mediation analysis with two mediating variables (handgrip strength and VO max) showed a significant indirect effect. When handgrip strength and VO max were included in the equations, the association between sex and each factor ceased to be significant.
This study highlights the potential benefits of muscular strength (handgrip) and VO max in the perceived risk scale, and the variable of age on this.
Clinical trial: NCT05544370 (pre-results).
研究心肺适能(最大摄氧量,VO2max)和肌肉力量与运动风险量表相关指标的关联,如感知能力、感觉寻求、竞争力、冒险行为和风险感知。
横断面研究。
西班牙穆尔西亚地区的高中。
377 名青少年参与(平均年龄:13.69±1.2 岁)。
体重、身高、Course-Navette 测试、上肢力量和心理教育因素,这些因素决定了儿童在学校发生运动事故的倾向,使用运动事故倾向量表进行评估。采用独立样本 t 检验、逐步多元线性回归模型和多元中介分析。
分析显示,在身高、VO2max、握力和问卷的所有因素方面,性别存在显著差异(p=0.02-<0.01)。具有更高 VO2max、握力测试中更强力量和更大年龄的青少年在因素 1 和 3 中得分更高。在因素 2 中得分更高与更好的 VO2max 和握力测试中的力量相关。握力测试中更强的力量和更年轻的年龄与因素 4 和 5 中更高的得分相关。具有两个中介变量(握力和 VO2max)的中介分析显示出显著的间接效应。当握力和 VO2max 被纳入方程时,性别与每个因素之间的关联不再显著。
这项研究强调了肌肉力量(握力)和 VO2max 在感知风险量表中的潜在益处,以及年龄变量在这方面的作用。
