- Impact of exercise on bone health in haemodialysis patientsPublication . Cardoso, Daniela FilipaChronic Kidney Disease (CKD) is associated with mineral and bone disorders (MBD), which can induce bone loss in those patients. These bone comorbidities tend to aggravate with disease progression, leading to greater bone loss in later stages of kidney disease, particularly those on dialysis. Furthermore, dialysis patients tend to have low levels of physical function and physical activity (PA), that could contribute to greater bone loss. However, exercise has been pointing as a non-pharmacological adjunct strategy to improve bone health in e.g., individuals with osteoporosis; however, there is still little evidence regarding its effect in CKD patients, particularly those on haemodialysis (HD) treatment.
- Intradialytic exercise in hemodialysis patients - Implementation and effectiveness on long-term patient outcomesPublication . Martins, Pedro Miguel PereiraHemodialysis (HD) patients have high levels of inactivity that are associated with poor health outcomes. Since 2005, the National Kidney Foundation guidelines (Kidney Disease Outcomes Quality Initiative) recommend chronic kidney disease (CKD) patients to perform aerobic exercise for 30 minutes most, if not all, days per week (1). Apparently, this ambiguous recommendation have not inspired the nephrology community to improve physical activity (PA) levels, since inactivity remains an hallmark of this population (2). This thesis includes a systematic review in which PA was associated with a lower mortality risk in end-stage kidney disease (ESKD) patients. Intradialytic exercise (IDE) could be a strategy to improve PA, since it is convenient for HD patients, being its implementation recommended by the UK Kidney Association (UKKA) (3). Nevertheless, little is known about the implementation and scalability of IDE and about its effectiveness in real-world conditions, including its association with relevant endpoints for this population.
- DOSE-RESPONSE EFFECTS OF A RECREATIONAL TEAM HANDBALL-BASED EXERCISE PROGRAMME ON CARDIOVASCULAR, METABOLIC AND MUSCULOSKELETAL BIOMARKERS OF INACTIVE OVER 50-YEAR-OLD MENPublication . Carneiro, Ivone Ferreira da Silva Moura
- THE SKILLS PROFILE OF THE PORTUGUESE LIFEGUARDPublication . Santiago, Paulo Miguel Pinto MoreiraDrowning is one of the leading causes of unintentional death worldwide; there are an estimated 372 000 drowning deaths every year. Drowning is quick and silent and it can occur in less than a minute. It is already considered a public health problem. The lifeguard's action can be regarded as a significant contribution to a change in this reality. However, in order to intervene safely, the lifeguard must possess a set of technical, physical and psychological skills that enable an effective rescue
- The role of acceleration and deceleration in agility, change of direction speed and running in soccer players’ movementsPublication . Silva, Hugo Flávio Rodrigues daMonitoring accelerations and decelerations in soccer activities entails specific challenges for practitioners and researchers. This thesis aims to provide a new proposal to monitor accelerations and decelerations, by addressing those challenges: the use of minimum effort duration, the utilization of fixed and arbitrary thresholds, and by highlighting the importance of accelerations and decelerations efforts in agility, change of direction speed, and speed displacements.
- UNDERSTANDING ESPORTS PLAYERS’ HEALTH A first step towards adequate medical carePublication . Pereira, Ana MonteiroOs esports são já parte da sociedade contemporânea. A exigência das competições de esports e os riscos que podem advir da participação, treino e profissionalização em atividades relacionadas com esports podem influenciar a saúde dos praticantes de esports. Assim, a presente tese aprofunda o conhecimento mais recente sobre parâmetros de saúde nos praticantes de esports.
