The aim of this study was to determine the short-term effects of cycle training on basic cycling skills in children from the 4th grade of elementary school. Furthermore, the influence of gender, socio-economic status (SES) and initial cycling skills level on the effects of the cycle training was investigated.
Five participating schools were randomly assigned to the intervention (n=3) or control condition (n=2). Children's cycling skills were assessed, using a practical cycling test, at baseline and immediately after the intervention. At baseline, all participating children received a short parental questionnaire on child's demographic and family factors. After the pre-test, cycle training took place only in the intervention schools. Repeated measure analyses were conducted to evaluate the effectiveness of the cycle training.
The cycle training had a statistically significant effect on children's total cycling skill (F=46.9, p<0.001). On mounting the bicycle and start to cycle (F=2.6, p=0.11), cycling one handed (F=2.0, p=0.16), and cycling on a sloping surface (F=1.5, p=0.23), no statistically significant effects were detected. On all other cycling skills, time×condition interaction effects were statistically significant. Gender, SES and initial cycling skills level had no significant influence on the effects of the cycle training.
This study showed that a cycle training of only three sessions was effective to improve children's cycling skills at short term and that cycle training within a traffic-free environment seems to be a useful first step in the development of safe cycling behaviors.
本研究旨在确定周期性训练对小学四年级儿童基本自行车技能的短期影响。此外,还研究了性别、社会经济地位(SES)和初始自行车技能水平对周期性训练效果的影响。
随机将五所参与学校分配到干预组(n=3)或对照组(n=2)。在基线和干预后立即使用实际自行车测试评估儿童的自行车技能。在基线时,所有参与的儿童都接受了关于儿童人口统计和家庭因素的简短家长问卷。在预测试之后,仅在干预学校进行周期性训练。进行重复测量分析以评估周期性训练的效果。
周期性训练对儿童的总体自行车技能有统计学上显著的影响(F=46.9,p<0.001)。在骑自行车和开始骑车(F=2.6,p=0.11)、单手骑车(F=2.0,p=0.16)和在倾斜表面上骑车(F=1.5,p=0.23)方面,未检测到统计学上显著的效果。在所有其他自行车技能方面,时间×条件交互作用效果具有统计学意义。性别、SES 和初始自行车技能水平对周期性训练效果没有显著影响。
本研究表明,仅进行三次周期性训练就可以有效提高儿童的自行车技能短期,在无交通环境中进行周期性训练似乎是发展安全骑自行车行为的有用第一步。
