Objectives: This study aimed to evaluate the authenticity for application of Cooper’s 12 min run test (CRT) to predict VO2max in male and female boxers in India.Methods: Participants of both sexes (male=70, female=60) were recruited from different boxing clubs in India, and randomly allocated to the study group (male = 40, female = 30) and cross-validation group (male = 30, female = 30). VO2max was directly estimated by bicycle exercise with progressive workload followed by expired gas analysis in a Scholander micro-gas analyzer. CRT method was used for indirect prediction of VO2max.Results: Predicted VO2max (PVO2max) and directly measured VO2max were found to be significantly (p<0.001) different in the study groups of both sexes, with wide range of limit of agreement between PVO2max and VO2max. This indicates the inapplicability of existing CRT protocol in the male and female boxers. Simple linear regression was computed owing to existence of significant positive correlation (r = 0.84 and 0.89 in males and females, respectively; p<0.001) between VO2max and distance covered in the run test. These newly derived norms depicted insignificant variation between PVO2max and VO2max in the confirmatory group of both sexes.Conclusions: Modified equations computed in this study for the prediction of cardiorespiratory fitness in terms of VO2max by CRT were recommended in male and female Indian boxers.
目的:本研究旨在评估应用Cooper 's 12 min run test (CRT)预测VO<sub>2max</sub>在印度的男女拳击手中方法:从印度不同拳击俱乐部招募男女参与者(男性70人，女性60人)，随机分为研究组(男性40人，女性30人)和交叉验证组(男性30人，女性30人)。VO< sub> 2 max< / sub>在肖兰德微量气体分析仪中进行过期气体分析后，通过自行车运动和渐进式工作量直接估计。采用CRT法间接预测VO<sub>2max</sub>结果:预测VO<sub>2max</sub>(PVO<sub>2max</sub>)和直接测量的VO<sub>2max</sub>在两性研究组中存在显著差异(p<0.001)， PVO<sub>2max</sub>和VO< sub> 2 max< / sub>。这表明现有的CRT方案在男女拳击手中不适用。由于存在显著的正相关(r分别为0.84和0.89)，因此计算简单线性回归;p<0.001)在VO<sub>2max</sub>以及跑步测试中所跑的距离。这些新导出的规范描述了PVO<sub>2max</sub>和VO< sub> 2 max< / sub>在两性确认组中。结论:修正了本研究计算的以VO<sub>2max</sub>推荐给印度男性和女性拳击手服用

Objectives: To enhance the confidence of children and adolescents with medical conditions and disabilities to engage in healthy, active lifestyles. Children with medical conditions and disabilities often exhibit more sedentary lifestyles relative to peers and are at increased risk of poor health outcomes. Clinical experience suggests physical activity confidence is an important factor influencing physical activity participation.Methods: This randomized controlled trial evaluates an evidence-based intervention targeting physical activity confidence among children and adolescents with medical conditions and disabilities. Potential participants, 8 to 18 years of age diagnosed with a medical condition or disability, will be screened for adequate physical activity motivation but a lack confidence. Consenting participants (n=128) will be randomized 1:1 to a 12-week in-person or virtual physical activity intervention (24 hours/week total) led by a Registered Kinesiologist or control (assessments only). The intervention will combine physical activity participation with education about physical activity knowledge, goal setting, motivation and self-management. Primary outcomes are self-reported physical activity confidence and motivation at baseline, post-intervention and three months following intervention completion. A secondary outcome will be daily physical activity minutes assessed by accelerometry. A repeated measures mixed model will be used to compare outcomes between the in-person intervention, virtual intervention, and control groups (alpha=0.05).Conclusions: This trial aims to assess the impact of a novel application of behaviour change theory on physical activity confidence among children and adolescents living with medical conditions or disabilities. Increased physical activity confidence, knowledge and skills could enable these youth to lead a more active lifestyle.
