This study investigated the longitudinal associations of physical activity and circulating amino acids concentration in peripubertal girls. Three hundred ninety-six Finnish girls participated in the longitudinal study from childhood (mean age 11.2 years) to early adulthood (mean age 18.2 years). Circulating amino acids were assessed by nuclear magnetic resonance spectroscopy. LTPA was assessed by self-administered questionnaire. We found that isoleucine, leucine and tyrosine levels were signifcantly higher in individuals with lower LTPA than their peers at age 11 (p<0.05 for all), independent of BMI. In addition, isoleucine and leucine levels increased signifcantly (~15%) from childhood to early adulthood among the individuals with consistently low LTPA (p<0.05 for both), while among the individuals with consistently high LTPA the level of these amino acids remained virtually unchanged. In conclusion, high level of physical activity is associated lower serum isoleucine and leucine in peripubertal girls, independent of BMI, which may serve as a mechanistic link between high level of physical activity in childhood and its health benefts later in life. Further studies in peripubertal boys are needed to assess whether associations between physical activity and circulating amino acids in children adolescents are sex-specific. ...

Leisure-time physical activity from adolescence to late middle age and its associations with the COVID-19 pandemic : A 45-year follow-up Laakso, Perttu T.T.; Huotari, Pertti; Tolvanen, Asko J.; Kujala, Urho M.; Laakso, Lauri H.T.; Jaakkola, Timo T. (Routledge, 2022)We aimed to investigate the association of self-reported leisure-time physical activity (LTPA) over a 45-years from adolescence to late middle age mediated by LTPA in early middle age. We also explored whether LTPA in ...
Longitudinal associations among cardiorespiratory fitness and objectively measured moderate-to-vigorous physical activity of Finnish schoolchildren Jaakkola, Timo; Huhtiniemi, Mikko; Salin, Kasper (Oxford University Press (OUP), 2022)Children and adolescents' engagement in physical activity has decreased in most Western countries across the previous three decades. Therefore, increasing number of researchers are investigating antecedents of physical ...
Cross-Sectional and Longitudinal Associations between Leisure Time Physical Activity, Mental Well-Being and Subjective Health in Middle Adulthood Kekäläinen, Tiia; Freund, Alexandra M.; Sipilä, Sarianna; Kokko, Katja (Springer Netherlands, 2020)Previous studies have shown that participation in leisure time physical activity is related to better mental well-being and subjective health. However, the associations between different types of leisure time physical ...
