Exercise and Muscle Performance

4.3K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Area of Science:

  • Pediatric Health
  • Exercise Science
  • Public Health

Background:

  • Extracurricular physical activity (PA) is crucial for children's health and development.
  • Understanding trends in research on PA in children is vital for public health initiatives.
  • Previous research has varied in methodology and focus.

Purpose of the Study:

  • To systematically review scientific literature on extracurricular physical activity (PA) in Western children aged 6-12 years.
  • To identify common research methodologies and outcome measures used in this field.
  • To synthesize findings from studies published between 1990 and 2013.

Main Methods:

  • Comprehensive literature search of Medline/PubMed, Scopus, and Google Scholar databases.
  • Inclusion of articles published from January 1990 to May 2013.
  • Analysis of 104 selected publications, categorizing intervention studies and reviews.

Main Results:

  • Body composition parameters, especially body mass index (BMI), are the most frequently used outcome measures.
  • Maximum aerobic capacity is the second most common assessment metric.
  • Intervention studies exhibit methodological heterogeneity, yet show consistent trends in certain aspects.
  • The majority of review articles are systematic and incorporate meta-analyses.

Conclusions:

  • Body mass index (BMI) is a widely adopted and effective metric for evaluating the impact of physical activity interventions in children.
  • Future research should aim for greater methodological consistency in intervention studies.
  • Systematic reviews and meta-analyses are valuable tools for synthesizing evidence on children's physical activity.
