The results of this novel longitudinal study challenge the notion that differences in training status in young people are only evident once a maturational threshold has been exceeded.
The aim of this study was to investigate the effects of exercise training on the peak oxygen uptake (peak VO2) and blood lipid profile of 13 to 14‐y‐old postmenarcheal girls. Treadmill determined peak VO2, total cholesterol, high density lipoprotein cholesterol, low density cholesterol, and triglycerides were the outcome measures assessed at baseline and following exercise training. Twenty girls completed a 20‐wk programme of exercise training which involved maintaining the heart rate at 75–85% maximum for 20 min, three times per week. Heart rate was rigorously monitored using telemetry throughout each training session. Eighteen girls acted as the control group. There were no significant (p≫ 0.05) changes in the outcome measures following the training programme. Conclusions: These findings suggest that exercise training of this frequency, intensity and duration for a period of 20 wk has no significant effect on either the peak VO2 or blood lipid and lipoprotein profile of normolipidaemic, postmenarcheal girls.
Background: Women in rural areas are less likely to engage in physical activity (PA) compared with their urban counterparts. It can be even more challenging for BC patients due to the sequelae of their cancer and treatment. A quality improvement project in our cancer center evaluating leisure time activity among BC patients identified that about half the responders were sedentary or insufficiently active. Only one third were aware of the recommendation to achieve 150 active minutes per week while more than half reported not meeting the goal. Lack of motivation was quoted as the main reason for not meeting the goal by one-third of the responders. Goal setting has been an integral part of cardiac rehabilitation and behavior change techniques. It has shown to increase participation and motivation. We performed a combined analysis of collaborative interventions in NNE to identify if effective goal setting can overcome the barriers to PA among BC survivors. Methods: 5 IRB-approved interventions promoting PA among BC patients across 3 states were included. Studies were stratified according to the stages of treatment, the types of intervention and whether goal-setting was used. Pooled effects were calculated using Comprehensive Meta-Analysis software and R package metafor (v.2.0.0) with the maximum-likelihood configuration. Subgroup analyses were conducted based on the goal-setting criteria. Results: The 5 studies examining 4 exercise interventions are shown in the table below.

Home-based programs were used in W12051 and D12030. Goal-setting was used in all the studies except for the UVM study which used a supervised program with self-reporting. Weighing by percentage of patients completing the program, the pooled change in PA was 56.6% (95% CI=24.2-89.1%). Pooled PA for the goal-setting subgroup was nearly twice as high as the without-goal-setting subgroup (74.3% and 39.5%, respectively). Conclusion: Cancer centers with large catchment areas need to design creative approaches to encourage PA among the BC survivors. With the lack of motivation as the most common barrier to achieving the recommended PA, goal-directed programs can be helpful by creating attainable targets as well as providing emotional and psychological support. In addition, geographical barriers need to be addressed through interventions like internet-based programs, personal tracking devices, and small-group social activities.
