Introduction
Currently, I'm working on research projects related to: (1) Promotion of physical activity in young people from the contexts of school, physical education and organized sport (2) Validation and adjustment of self-report measures to assess physical activity in young populations. (3) Motivational processes in physical education. My research is based on both quantitative and qualitative methods.

Background: The need for novelty has been recently proposed as a candidate need within basic psychological needs theory (BPNT). In physical education (PE), research has shown that meeting students’ need for novelty is often positively associated with enhanced (and negatively associated with impaired) pupils’ well-being. Frustrating students’ novelt...

Introduction: Physical activity (PA) entails several physical and psychosocial benefits which optimize bariatric surgery outcomes. Although bariatric patients usually increase their satisfaction with their body shape after surgery, little is known about the role of postoperative PA in this regard. From a mixed-method approach, this study examines b...

This study examines the associations between pre-to post-intervention changes in motivation and physical activity (PA) levels of bariatric patients involved in a 6-month postoperative PA program based on self-determination theory (SDT). We also explore the extent to which patients’ perception of autonomy support and basic psychological ne...
Aging is increasing worldwide; hence, aging-related health is also more relevant. Well-programmed physical exercise is now an indispensable tool to achieve active aging and preserve older people’s health.

Questions
Questions (11)
I am interested in knowing if there is any research work exploring factors that may affect the way in which girls and boys (aged 9-12 yrs.) complete physical activity self-report measures (e.g., questionnaires). Do you know of any studies that indicate that girls record/adjust their subjective physical activity better (compared to device-measured physical activity) than boys?
Hello everybody! We are carrying out a research where we associate baseline to post-intervention changes between motivation and physical activity variables. My question is the following: In an experimental group, if I have a NEGATIVE association between INCREASES in introjected regulation and DECREASES in sedentary activity, how should I interpret it? Do you have any example of reference that describes this type of results between changes or similar? Many thanks in advance! Cheers.
Hello everybody. I am interested in conducting a study with data from a randomized study we did in 2010. However, we did not register the trial on pages like ClinicalTrials.gov in that year. Is it possible to do it now? Implications? Problems with reviewers? Possible solutions?
I'm looking for validated instruments to measure drug and alcohol use in adolescents, or even causes or risk factors that lead (or not) to this type of behaviour.
I want to do a systematic review about this and I need a lot of articles. Can you help me? Thank you very much!
WHO says that health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.
I'm interested in knowing possible variations that you would do and your opinions.
For example, to analyze weekdays and weekend physical activity patterns. Thank you.
Can you recommend me any article?
