Objective: The aim of the review is to evaluate the belief that moderate-to-vigorous-intensity physical activity (MVPA) declines during adolescence.
Methods: Evidence from different studies are part of the review.
Results: The body of evidence does not support the hypothesis that MVPA declines during adolescence.
Introduction
MVPA is said to provide benefits on the health of children and adolescence.
There are recommended MVPA duration for children and adolescence.
There is a belief that MVPA declines during adolescence.
Methods
Using the results of different studies, the hypothesis about the decline of MVPA will be examined.
Results
Based on a systematic review, there is no significant evidence on the decline of MVPA during adolescence.
Based on the review of recent longitudinal studies of changes in MVPA, MVPA does not decline during adolescence.
Pieces of evidence on increases in sedentary behavior across childhood and adolescence suggest that sedentary behavior displaces physical activity during childhood and not during adolescence.
Based on the evidence from the International Children’s Accelerometry Database (ICAD), the changes in MVPA may be positively or negatively influenced by the environment.
Based on the Iowa Bone Development Study, there is a need for a more nuanced assessment of age-related changes in MVPA.
The belief in the decline of MVPA remains despite the fact that there is no substantial evidence supporting it.
There is a need for more longitudinal studies to further examine the changes in MVPA.
Conclusion
There is no significant evidence supporting the belief that MVPA declines during adolescence.
