The authors describe the implementation of a 3-week dietary intervention in elite race walkers at the Australian Institute of Sport, with a focus on the resources and strategies needed to accomplish a complex study of this scale. Interventions involved: traditional guidelines of high carbohydrate (CHO) availability for all training sessions; a periodized CHO diet which integrated sessions with low and high CHO availability within the same total CHO intake; and a ketogenic low-CHO high-fat diet. Seven-day menus and recipes were constructed for a communal eating setting to meet nutritional goals as well as individualized food preferences and special needs. Menus also included nutrition support before, during, and after exercise. Daily monitoring, via observation and food checklists, showed that energy and macronutrient targets were achieved. Diets were matched for energy (∼14.8 MJ/d) and protein (∼2.1 g·kg−1·day−1) and achieved desired differences for fat and CHO, with high CHO availability and periodized CHO availability: CHO = 8.5 g·kg−1·day−1, 60% energy, fat = 20% of energy and low-CHO high-fat diet: 0.5 g·kg−1·day−1 CHO, fat = 78% energy.  There were no differences in micronutrient intake or density between the high CHO availability and periodized CHO availability diets; however, the micronutrient density of the low-CHO high-fat diet was significantly lower. Daily food costs per athlete were similar for each diet (∼AU$ 27 ± 10). Successful implementation and monitoring of dietary interventions in sports nutrition research of the scale of the present study require meticulous planning and the expertise of chefs and sports dietitians. Different approaches to sports nutrition support raise practical challenges around cost, micronutrient density, accommodation of special needs, and sustainability.

Background:

Kenya’s 2016 report card aimed to highlight the health and well-being of Kenyan children and youth using the best available evidence on the physical activity of Kenyan children and youth. The report pointed at areas where Kenya was succeeding and areas where more action is required.

Methods:

Inclusive analyses of available data sources on the core indicators related to physical activity and body weights of Kenyan children and youth (5 to 17 years) were conducted. These were assigned grades based on a set of specific criteria.

Results:

Results show that Active Play, Active Transportation, Overweight and Obesity, and Sedentary Behavior were favorable with a grade of B. Overall Physical Activity, Organized Sport Participation, and School (infrastructure, policies, and programs) each received a grade of C, while Family and Peers, Government and Nongovernment organizations, as well as the Community and the Built Environment were assigned grade D.

Conclusions:

Over 72% of Kenyan children and youth use active transportation to and from school and in their daily lives. Although majority of the children and youth have normal body weight, there is need to ensure that they meet and maintain the physical activity levels recommended by the World Health Organization. More needs to be done especially in relation to the governmental and nongovernmental organizations, organized sports participation, as well as involvement of family and peers in promoting healthy active lifestyles among Kenyan children and youth. More representative data for all indicators are required in Kenya.

Background:

The Venezuelan Report Card on Physical Activity for Children and Youth is the first assessment of information related to physical activity in Venezuela. It provides a compilation of existing information throughout the country and assesses how well it is doing at promoting opportunities for children and youth. The aim of this article is to summarize the information available.

Methods:

Thirteen physical activity indicators were graded by a committee of experts using letters A to F (A, the highest, to F, the lowest) based on national surveys, peer review studies, and policy documents.

Results:

Some indicators report incomplete information or a lack of data. Overweight and Obesity were classified as A; Body Composition and Nongovernmental Organization Policies as B; Municipal Level Policies as C; and Overall Physical Activity Levels and National Level Policies as D.

Conclusions:

63% of children and youth have low physical activity levels. Venezuela needs to undergo a process of articulation between the several existing initiatives, and for said purposes, political will and a methodological effort is required. Investments, infrastructure, and opportunities will be more equal for all children and youth if more cooperation between institutions is developed and communication strategies are applied.

Background:

The report card was a synthesis of the best available evidence on the performance of Zimbabwean children and youth on key physical activity (PA) indicators. The aim of this article was to summarize the results from the 2016 Zimbabwe Report Card.

Methods:

The Report Card Working Group gathered and synthesized the best available evidence, met, discussed and assigned grades to 10 indicators based on the Active Healthy Kids Global Alliance global matrix grading system.

Results:

The indicators were graded as follows: overall PA (C+), organized sport participation (B), active play (D+), active transportation (A-), sedentary behaviors (B), school (D), family and peers (Incomplete), community and the built environment (F), government (D) and nongovernmental organizations (Incomplete).

Conclusions:

Although the majority of children used active transport, played organized sports and engaged in acceptable levels of PA, most of them did not meet the recommended hours of unstructured/unorganized play per day. At present, there are limited data to accurately inform the Zimbabwe Report Card therefore studies employing robust research designs with representative samples are needed. Zimbabwe also needs to prioritize policies and investments that promote greater and safe participation in PA among children and youth.

Background:

The Nigerian Report card on Physical Activity (PA) in Children and Youth was first developed in 2013 to inform practice and policy on healthy living and prevention of noncommunicable diseases among Nigerian children and youth. This article summarizes the results of the 2016 report card and provides updated evidence on the current situation in Nigeria.

Methods:

A comprehensive review of literature was undertaken by the Report Card Working Group. Grades were assigned to 10 PA indicators based on the criteria used for the 2013 edition.

Results:

Grades assigned to the indicators were Overall PA, D; Active Play and Leisure, C; Active Transportation, B; Sedentary Behaviors (screen-based, F and nonscreen-based, D); Overweight and Obesity, A; PA in Schools, C-; Government/Nongovernment Organizations/Private Sector/Policy, B. The following indicators were graded as Incomplete: Organized Sport and PA, Community and Built Environment, and Family and Peers.

Conclusions:

The overall PA levels of Nigerian children and youth seemed to be declining compared with the 2013 Report card but with slight improvement in active play and leisure, and PA in school settings. A substantial number of Nigerian children and youth still have high sedentary behaviors, overweight and obesity. Efforts are needed to promote PA among them.
