    Youth Physical Activity Myths

    Debunking 10 Common Myths and Misperceptions about Youth Physical Activity

     

    Key Messages:

     

    1. Regular participation in moderate to vigorous physical activity (MVPA) including muscle and bone strengthening exercise is known to improve cardiorespiratory and neuromuscular fitness and health, while providing the potential to also improve emotional, social and cognitive well-being.

     

    2. The impact of physical inactivity during the growing years on lifelong pathological processes and associated health care concerns have created an urgent need to dispel common myths and misperceptions associated with youth physical activity.




    Regular participation in active play, exercise, and sport activities in the context of family, school and community programs is recognized as a powerful marker of health in children and adolescents. Regular participation in moderate to vigorous physical activity (MVPA) including muscle and bone strengthening exercise is known to improve cardiorespiratory and neuromuscular fitness and health, while providing the potential to also improve emotional, social and cognitive well-being. Furthermore, girls and boys who participate in a variety of physical activities early in life tend to be more active later in life. Yet a growing number of modern-day youth are failing to accumulate at least 60 minutes of MVPA daily and too many girls and boys are disconnected from school- and community-based exercise and sport programs.

    The impact of physical inactivity during the growing years on lifelong pathological processes and associated health care concerns have created an urgent need to dispel common myths and misperceptions associated with youth physical activity. Concerted efforts are needed to design evidence-based youth exercise and sport programs and inform parents and providers about the pleiotropic benefits of daily MVPA that is consistent with the developmental needs, abilities and interests of all children and adolescents. Without a change in our current philosophy, it is likely that the current trajectory of low physical inactivity will continue unabated and new health care concerns will begin to emerge.

    1. Children “outgrow” physical inactivity.

    Inactive children tend to become inactive adolescents who lack the requisite competence and confidence in their physical abilities to participate regularly in exercise and sport activities. Since physical activity is a learned behavior that is influenced by a child’s family, friends and environment, girls and boys need regular opportunities to engage in the right amount of MVPA early in life to prevent the inevitable cascade of adverse health outcomes later in life.

    2. Continuous physical activity is best.

    Watching girls and boys on a playground or sports field supports the premise that all types of physical activity – whether continuous, sporadic or in bouts – can offer observable health and fitness value to children and adolescents. The key is to expose youth to active play, exercise and sport activities that are physically challenging and mentally engaging, and this will often come in the form of intermittent exercise.

    "girls and boys who participate in a variety of physical activities early in life tend to be more active later in life"


    3. Children are miniature adults.

    Children are physically and psychosocially less mature than adults. As such, girls and boys are physically active in different ways and for different reasons than older populations. While adults may want to improve their cardiometabolic health or body composition, most children participate in exercise and sport programs to have fun, make friends and learn something new.

    4. Fundamental movement skills are innate.

    Just like the skills of reading and writing, fundamental movement skills such as jumping, kicking and throwing are learnt movement patterns that should be practiced and reinforced with qualified instruction throughout the growing years. The early years of life are an ideal time to capitalize on the plasticity of the neuromuscular system to adapt to motor skill training. As such the need to expose children and adolescents to a variety of different activities to help develop movement skills should be recognized in national physical activity guidelines.

    5. Resistance training is unsafe for children.

    With qualified instruction and technique driven progression, resistance training can be a safe, effective and enjoyable activity for children. Resistance training can include simply working against body weight as well as working against external loads, such as medicine balls, resistance bands or free weights. The belief that resistance training will harm the developing skeleton is inconsistent with the needs of modern-day youth. In fact, resistance training is a potent stimuli for strengthening muscle and bone and can help youth achieve the global physical activity recommendation of partaking in muscle and bone strengthening exercise at least three times per week.

    6. Start training in high school.

    Notwithstanding the potential benefits of exercise training for adolescents, training-induced gains in physical fitness are also observable in young children. Since positive behaviors established early in life tend to track or carry over into adulthood, the best approach is to expose young girls and boys to skill-building games and exercise programs early in life.

    7. Sports practice is enough.

    While sports provide a needed opportunity for MVPA, sports practice is often insufficient to accumulate enough daily physical activity. Girls and boys should be physically active throughout the whole day with active transportation, physical education, recreational exercise and outdoor play activities.

    8. Young athletes should specialize.

    Early sports specialization has been linked with increased injury risk and higher rates of dropping out of sport. Greater sport diversification early in life – tempered with appropriate rest and preparatory conditioning – develops physically literate youth who possess a diverse range of movement skills that facilitate lifelong engagement in exercise and sport activities.

    9. Focus on the physical.

    Youth physical activity is not just about accumulating 60 minutes of MVPA daily. Learning a variety of movement skills, discovering special talents and fostering health behaviors are equally important strategies for sparking an ongoing interest in active play, exercise and sport activities. This is where the quantitative aspects of youth physical activity need to be balanced with the qualitative aspects of motivation, inclusion, and enjoyment.

    10. Long-term athletic development is just for young athletes.

    All girls and boys should participate in exercise and sport programs that are purposely designed to enhance their ability to move competently, confidently and consistently in a variety of settings with speed, style and precision. Because athleticism is grounded in both health- and skill-related components of physical fitness, the concept of long-term athletic development should be applied to inactive youth as well as young athletes.

  • Skeletal Muscle, Bone and Connective Tissue | 2020 ACSM Annual Meeting Highlighted Sessions

    by Caitlin Kinser | Jan 16, 2020
    blog_am20_skeletalmuscle

    It is a pleasure to begin my first year as ACSM topical representative for Skeletal Muscle, Bone and Connective Tissue. The 2020 ACSM Annual Meeting will feature a number of outstanding sessions on the interactions between exercise, skeletal muscle, bone and connective tissue health. There are three sessions that I think will be of particular interest to conference attendees. The first is a highlighted symposium entitled, “Macronutrients and Muscle Protein Turnover During Weight Loss.” This session is scheduled for Friday, May 29, 2020 from 9:30 AM -11:30 AM. The symposium will be chaired by myself and features three outstanding speakers; Stuart Phillips, Ph.D., FACSM, from McMaster University, Stefan Pasiakos, Ph.D., FACSM, from the US Army Research Institute of Environmental Medicine and Jamie Baum, Ph.D., from University of Arkansas. This session will highlight the role in which protein quality and exercise training can optimize loss of fat mass and preserve lean mass during weight loss. The key molecular mechanisms in which muscle protein turnover is regulated during different stages of energy balance and the influence of macronutrient composition on key regulatory pathways will be highlighted.

    The second symposium entitled, “Lactate as a Signaling Molecule” features four of the leading experts in the world on the topics of lactate and metabolism. The session is scheduled for Thursday, May 28, 2020 from 1:30 PM-3:30 PM. Speakers include, George Brooks, Ph.D., FACSM, from University of California at Berkeley, Takeshi-Hashimoto, Ph.D., from Ritsumeikan University, Laurie Goodyear, Ph.D., from Harvard Medical School/Joslin Diabetes Center and Ralph Deberardinis, M.D., Ph.D., from University of Texas Southwestern Medical School. This session will provide an update on the role in which lactate acts as a signaling molecule with autocrine, paracrine, and endocrine functions. Dr. Hashimoto will describe how lactate accumulation during exercise signals metabolic adaptations in skeletal muscle, Dr. Goodyear will describe how lactate influences energy substrate partitioning in exercise via the TGF-B signaling pathway, and Dr. Deberardinis will discuss the “Warburg Effect” and new findings on the role of lactate signaling in cancer.

    The final symposium that I would like to highlight is entitled, “Exercise and Extracellular Vesicles (ExerVs): Identification of the Molecular Basis for Health Benefits.” This session is scheduled for Saturday, May 30, 2020 from 9:00 AM-11:00 AM and will feature four of the leading experts in the field of muscle biology. Speakers include Marni Boppart, Ph.D., FACSM, from the University of Illinois, Eva-Maria Kramer-Albers, Ph.D., from University of Mainz and John McCarthy, Ph.D., and Esther Dupont-Versteegden, Ph.D., from the University of Kentucky. Exosomes are small vesicles secreted by most cells that contain proteins and genomic materials and have recently gained attention for their ability to serve as intercellular messengers to facilitate health benefits. This session will describe how cells can release ExerVs during exercise, and how these vesicles work to deliver regenerative peptides and noncoding RNAs that mediate crosstalk between tissues and lead to skeletal muscle regenerative health benefits.

  • Medicine & Science in Sports & Exercise: Most Read Articles & Conversation Starters in 2019

    by Caitlin Kinser | Jan 13, 2020

    In 2019, Medicine & Science in Sports & Exercise (MSSE) published 299 articles, amounting to 2,620 pages of text. These articles were published out of approximately 1,300 submissions at an acceptance rate of 27.8%. As expected of the American College of Sports Medicine’s (ACSM) flagship journal, the scientific content of these articles was broad-based and representative of the varied interests of ACSM’s membership.

    blog_msse 2019 reviewOne measure of interest in published articles is the number of times the online version of each paper is viewed. This online content can be viewed either through an institutional subscription to the journal (Ovid) or through the journal website itself. Viewing frequency often varies between these two platforms. However, unsurprisingly, the most viewed MSSE articles in 2019 were generally position stands or consensus statements. However, a couple of 2019 original science articles made the top 10 most viewed list on the journal website. First, Schoenfeld and colleagues identified the strength and hypertrophy results of low- (one set per training session), moderate- (three sets per session) and high-volume (five sets per session) resistance exercise training over a period of eight weeks. The participants were healthy males from a university population who had consistently lifted weights at least three times per week for a minimum of one year. Muscle hypertrophy increased in a dose-respondent manner with those in the higher volume groups experiencing greater improvements. However, strength gains were not significantly different among the groups. The important practical implication is that strength gains do not necessarily require a large time commitment. In the other 2019 article that was among the top ten most viewed, McMillan and co-authors investigated the effect of exercise during pregnancy on infant neuromotor skills at one month of age. They found that infants of women in the exercise group scored higher on four of the five variables of the Peabody Developmental Motor Scales, 2nd edition. If these improved neuromotor skills subsequently lead to greater physical activity in childhood, this could be extremely important for overall health, perhaps extending even into adulthood.

    Social impact of scientific articles is evaluated by the altmetric score which considers tweets, blogs, Facebook mentions, coverage by news outlets, etc. The most mentions for MSSE articles published in 2019 included papers that related to the energy cost of standing, various aspects of resistance exercise training, a statistical timetable for the sub-2-hour marathon and reviews of exercise and cancer. Notably, the cancer articles which cracked the top 10 in altmetric score only came out in November!

    Aside from the most accessed and most mentioned articles for 2019, I want to also particularly note the series of 14 articles relating reviews by the Physical Activity Guidelines Advisory Committee in the June issue of MSSE; Dr. William Kraus, current ACSM President, spearheaded this effort. Additionally, two sets of contrasting perspectives were published in 2019. The first of these debated the health risks of obesity with Glenn Gaesser and Steven Blair versus John Jakicic, Renee Rogers and Joseph Donnelly. The second contrasting perspectives on the degree to which DNA sequence variations contribute to variability in fitness and trainability was debated by Claude Bouchard and Michael Joyner. In the upcoming year, I am anticipating debates on the anaerobic threshold as well as hypoxic training in elite athletes.

    Regardless of article access and reading and social media mentions, the ultimate scientific impact shows up in citations in the scientific literature. It will be interesting to see the citations accumulated by these notable articles of 2019.
