Exercise improves depression through positive modulation of brain-derived neurotrophic factor (BDNF). A review based on 100 manuscripts over 20 years.

The aim of this review was to explore the relevant neurobiology and the association between peripheral levels of brain-derived neurotrophic factor (BDNF) and acute and short to long-term exercise regimes, as well as its relation to depression and antidepressant treatment. A 20-year literature search was conducted. The screening process resulted in 100 manuscripts.

Evaluation of health-related quality of life in physically active and physically inactive students during the COVID-19 pandemic in Iran.

Covid-19 is an acute respiratory syndrome that can effect on lifestyles. The aim of the present study was to compare the health-related quality of life (HRQoL), physical component summary (PCS) and mental component summary (MCS) scores in physically active (PA) and physically inactive (PI) during the Covid-19 pandemic. Three hundred and twenty-six (182 women; 144 men) studying at the Persian Gulf University participated in the study.

Developing a New Curvilinear Allometric Model to Improve the Fit and Validity of the 20-m Shuttle Run Test as a Predictor of Cardiorespiratory Fitness in Adults and Youth.

Background And Objectives: Doubts have been raised concerning the validity of the 20-m shuttle-run test (20 mSRT) as a predictor of cardiorespiratory fitness (CRF) in youth based on Léger's equation/model. An alternative allometric model has been published recently that is thought to provide, not only a superior fit (criterion validity) but also a more biologically and physiologically interpretable model (construct validity). The purposes of this study were to explore whether allometry can provide a more valid predictor of CRF using 20 mSRT compared with Léger's equation/model.
