May the Force Be with Youth: Foundational Strength for Lifelong Development.

Today's youth are weaker than previous generations, and measurable reductions in physical fitness are beginning to emerge. Without targeted initiatives that recognize the foundational importance of resistance training, weaker children and adolescents may be more likely to experience the inevitable consequences of neuromuscular dysfunction and less likely to experience the pleiotropic benefits of exercise and sport. Early exposure to strength-building activities is needed to prepare today's youth for ongoing participation in varied physical activities throughout this developmental phase of life.

Efficacy of Postprandial Exercise in Mitigating Glycemic Responses in Overweight Individuals and Individuals with Obesity and Type 2 Diabetes-A Systematic Review and Meta-Analysis.

Studies investigating the acute effect of postprandial exercise (PPE) on glucose responses exhibit significant heterogeneity in terms of participant demographic, exercise protocol, and exercise timing post-meal. As such, this study aimed to further analyze the existing literature on the impact of PPE on glycemic control in overweight individuals and individuals with obesity and type 2 diabetes (T2DM). A literature search was conducted through databases such as PubMed, CINAHL, and Google Scholar.

Integrative Neuromuscular Training in Adolescents and Children Treated for Cancer (INTERACT): Study Protocol for a Multicenter, Two-Arm Parallel-Group Randomized Controlled Superiority Trial.

Background: Improved survival rates for children and adolescents diagnosed with cancer call for novel strategies for reducing short- and long-term treatment-related side effects. These include the physical and metabolic sequelae that are exacerbated by sedentary behavior and treatment-induced toxicities. We aim to investigate the effect of an integrative neuromuscular training intervention during the first 6 months of anti-cancer treatment primarily on muscle strength, and secondarily on exercise capacity, physical function, markers of metabolic syndrome, dysmetabolism, and health-related quality of life during and after ended treatment.

Preliminary Report on the Train the Brain Project, Part II: Neuroplasticity of Augmented Neuromuscular Training and Improved Injury-Risk Biomechanics.

Context: Neuromuscular training (NMT) facilitates the acquisition of new movement patterns that reduce the anterior cruciate ligament injury risk. However, the neural mechanisms underlying these changes are unknown.

Objective: To determine the relationship between brain activation and biomechanical changes after NMT with biofeedback.

Attitudes and behaviors of physical activity in children: Findings from the Play, Lifestyle & Activity in Youth (PLAY) Questionnaire.

Background: The identified domains of child physical literacy include knowledge/understanding, behavior, motivation/confidence, and physical competency. Understanding physical literacy is critical to moving forward intervention efforts surrounding physical inactivity.

Objectives: To investigate physical literacy domains by presenting responses to the Play, Lifestyle & Activity in Youth (PLAY) questionnaire and analyze the relationship between comparable questions in the child and parent sections.

Efficacy of school-based interventions for improving muscular fitness outcomes in children: A systematic review and meta-analysis.

The World Health Organization recommends that children should engage in an average of 60 min of moderate-to-vigorous physical activity (MVPA) per day and should perform activities that strengthen muscle and bone at least 3 days a week. Public health professionals as well as pediatric researchers have identified schools as a strategic place to promote muscular strength development. Thus, the aim of this systematic review and meta-analysis was to investigate the efficacy of school-based exercise interventions for improving muscular fitness (MF) in children.

Effect of Time-Restricted Feeding on Anthropometric, Metabolic, and Fitness Parameters: A Systematic Review.

Time restricted feeding (TRF) as a form of intermittent fasting (IF) has gained popularity because its ability to reduce body mass (BM) without an emphasis on caloric restriction. However, how this dietary protocol may affect health, fitness, and performance in a relatively healthy cohort remains less clear. The purpose of this article was to systematically review the current literature concerning the effect of TRF on anthropometric, metabolic, and fitness parameters in normal-weight adults and overweight and obese individuals.

Comparison of fitness levels between elementary school children with autism spectrum disorder and age-matched neurotypically developing children.

Low physical fitness is associated with reduced physical activity and increased cardiovascular diseases. To date, limited research has compared physical fitness levels between children with and without autism spectrum disorder (ASD). Therefore, the primary aim was to investigate if differences in fitness levels exist between children with ASD and age-matched neurotypically developing children (ND).

An equation that uses heart rate index (HRI) defined as HR/HRrest to predict oxygen uptake (VO) in METs (e.g., METs = 6 × HRI - 5) has been developed retrospectively from aggregate data of 60 published studies.

Making a Strong Case for Prioritizing Muscular Fitness in Youth Physical Activity Guidelines.

Although evidence indicates that muscular fitness is foundational for ongoing participation in active play, exercise and sport, current national and international youth physical activity guidelines underplay the critical importance of strength-building activities during this developmental phase of life. In view of troubling trends in muscular fitness in today's youth, specific recommendations to address neuromuscular deficiencies are required. An understanding of the multidimensional development of youth physical inactivity and the importance of muscular fitness are needed to have the most significant impact on youth physical activity at the population level.
