“…Physical activity (PA) is an important modifiable factor in the improvement of children's cardiometabolic (Boddy et al 2014), musculoskeletal (Janz, Thomas, Ford & Williams, 2015), and psychological health (Ahn & Fedewa, 2011), and supports cognitive (Carson et al 2015) and fundamental movement skill development (Lubans, Morgan, Cliff, Barnett, & Okely, 2010). The UK Government recommends that children should accumulate at least one hour of moderate to vigorous intensity PA (MVPA) each day, and reduce time spent in sedentary behaviours (Department of Health.…”

This study explored parents' physical activity knowledge and perceptions of children's out-ofschool physical activity to formatively contribute to a family-based intervention design. Parents were largely unaware of the UK child physical activity guidelines and whether their child achieved the guidelines daily. Physical activity for many parents was attributed to healthy weight status, and the neighbourhood environment was perceived as unconducive to children's outdoor play which consequently increased the attractiveness of adult supervised organised activities. Family-based intervention engagement was considered as an important opportunity to increase physical activity knowledge, family time, and receive feedback on activity behaviours. Parental concerns related to intervention content and logistic and timing barriers.Consulting with parents in a formative sense prior to familial physical activity intervention facilitates intervention content to be aligned with family-specific perceptions and needs, and offers opportunities to communicate the relevance of programs to parents. This may aid subsequent intervention recruitment and engagement.

“…Through the work of the NOF-ASN scientific statement on development of peak bone mass coming out later this year, 2015, and in considering the top 10 research questions relating physical activity and bone health in children and adolescents (Janz et al, 2015), it became clear that there are obvious differences in how the disciplines of nutrition and physical activity address questions related to bone and other issues. Nutrition uses a reductionist approach with much more data on the effects of individual nutrients than for global diet patterns.…”

“…The article "Top 10 Research Questions Related to Physical Activity and Bone Health in Children and Adolescents" by Janz, Thomas, Ford, and Williams (2015) contributed to my supposition that there are many parallels between two of the most important fields-namely, physical activity and nutrition science, which study lifestyle choices that influence bone health. At a superficial level, this observation has been obvious for some time.…”

“…Thus, I readily accepted the invitation to elaborate on these comparisons with respect to the pressing research questions concerning development of peak bone mass. In this commentary, I will first summarize the work that went into the development of the NOF-ASN Scientific Statement and then will proceed with comparisons of the disciplines of physical activity and nutrition and will discuss how they differ in addressing the first 4 of the top 10 research questions provided by Janz et al (2015).…”

Lifestyle choices are attributed to 40% to 60% of adult peak bone mass. The National Osteoporosis Foundation (NOF) sought to update its 2000 consensus statement on peak bone mass and partnered with the American Society for Nutrition, which, in turn, charged a 9-member writing committee with using a systematic review approach to update the previous NOF guidelines. PubMed searches of the scientific literature from January 2000 through December 2014 were conducted on all relevant lifestyle choice factors and their relation to increasing bone mass during childhood and adolescence. The writing group concluded that there is strong evidence for the benefits of physical activity and calcium intake on bone mass accretion, moderately strong evidence for the benefits of vitamin D and dairy intake on bone mass and for physical activity on bone structure, and weaker evidence for other lifestyle choices. There were parallels and synergies between the benefits of diet and exercise on development of peak bone mass, but the type of evidence and public policy recommendations in the two disciplines differ in several important ways. Nutrition uses a more reductionist approach in contrast to physical activity, which uses a more global approach. This leads to differences in research priorities in the 2 disciplines. The disciplines can advance more quickly through collaboration and adoption of the best approaches from each other.

The weight-bearing exercise for better balance program improves strength and balance in osteopenia: a randomized controlled trial

[Purpose] This study investigated the effect of the Weight-bearing Exercise for Better Balance program on the strength of hip flexors, extensors, abductors, adductors, and knee flexors and extensors and balance in osteopenia. [Subjects and Methods] Twenty-four postmenopausal females with osteopenia volunteered to participate in this study and were randomly assigned into two equal groups of 12: the experimental and control groups. The Weight-bearing Exercise for Better Balance program was applied to the experimental group, while the control group did not receive any treatment. Isokinetic peak torque per body weight values of the hip flexors, extensors, abductors, adductors, and knee flexors and extensors were measured by Biodex System 3 isokinetic dynamometer for both groups before and after six weeks of the program. Balance was assessed in both groups using the Berg Balance Scale. [Results] There was a statistically significant increase in post-intervention mean values of all measured variables compared with pre-intervention values in the experimental group. Also, there was a statistically significant increase in post-intervention mean values of all measured variables except for those of the hip extensors in the experimental group compared with the control group. [Conclusion] The weight-bearing exercise for better balance program has significant effects on lower extremity muscle strength and body balance in postmenopausal females with osteopenia.
