Impact of high-performance sport on serum potassium values in athletes: a syste...
Tavares, Ana Sofia; Vieira, Daniela; Pires, Mariana Midões; Miranda, Vasco; Bellém, FernandoBackground: Potassium is an alkali metal and the most abundant cation in the body, which can be measured in serum, plasma, whole blood, and urine without preservatives. The release of potassium from the muscles into the bloodstream during intense exercise is related to the intensity of physical activity. Therefore, changes in the serum levels of potassium measured in the blood of individuals who practice sports...
Impact of non-therapeutic doses of anabolic steroids on glucose and insulin lev...
Tavares, Ana Sofia; Ferreira, Bárbara; Leite, Beatriz; Calixto, Carolina; Bellém, FernandoBackground: Anabolic androgenic steroids (AAS) are synthetic compounds with a chemical structure similar to testosterone. Bodybuilders frequently use them to increase muscle mass, and strength, and reduce body fat. However, AAS can also have adverse effects on health, including alterations in glucose and insulin levels. Aims: This systematic literature review aimed to collect and critically analyze studies that...
Lipoatrophia semicircularis: a case report
Almeida, Cláudia Sofia; Tavares, Ana SofiaIntroduction: Lipoatrophia semicircularis is a rare form of lipodystrophy localized in the thighs, forming a horizontal, symmetrical, and bilateral band. Although its pathogenesis is unknown there are some hypotheses described in the literature, namely: repeated microtrauma, electromagnetic lipolysis, a congenital defect of the lateral circumflex femoral artery, and factors related to climatic conditions inside...
Impact of supraphysiological doses of anabolic steroids on glucose and insulin ...
Tavares, Ana Sofia; Bellém, Fernando; Ferreira, Bárbara; Leite, Beatriz; Calixto, CarolinaTestosterone (TE) is an anabolic androgenic steroid (AAS) that promotes muscle growth and the maintenance of secondary sexual characteristics. Due to its aesthetic benefits, AASs have become popular in sports, typically administered orally or intramuscularly, with doses up to 100 times higher than the therapeutic dose. A therapeutic dose is safe and sufficient for the desired effect, while a supraphysiological ...
Protective factors of performance-enhancing substances use in a sample of Portu...
Tavares, Ana Sofia; Carolino, Elisabete; Teques, Pedro; Calmeiro, Luís; Serpa, SidónioBackground: Nowadays, the increased Performance Enhancing-Substance (PES) use in fitness centers is seen as a problematic phenomenon, since it has the potential to grow, and could be seen as an emerging public health and societal concern. Studies focusing on PES use among gym-goers are few and they do not provide information concerning protective factors that justify the refusing intention to use these substanc...
Effect of motor competence and health-related fitness in the prevention of meta...
Pombo, André; Cordovil, Rita; Rodrigues, Luis Paulo; Moreira, Ana Catarina; Borrego, Rute; Machado, Margarida; Costa, Vânia; Almeida, AnaPurpose: In the last decades we have seen an increase in sedentary behaviors and a decrease in physical activity in children when compared to past generations. This lifestyle is commonly associated with the development of clustering risk factors that define metabolic syndrome (MetS). Knowing that motor competence (MC) development can influence lifelong physical activity habits, it is reasonable to assume that c...
Impact of high-performance sport on serum potassium values in athletes: a syste...
Tavares, Ana Sofia; Bellém, Fernando; Vieira, Daniela; Miranda, Vasco; Pires, MarianaPotassium (K+) is a critical alkali metal and the most abundant cation in the body, primarily found inside cells. It's measurable in serum, plasma, whole blood, and urine. During intense exercise, potassium is released from muscles into the bloodstream, with levels related to exercise intensity. Potassium is essential for cell polarization and transmitting electrical impulses in the heart, so fluctuations in se...
Impact of anabolic steroid consumption on biochemical and hematological paramet...
Tavares, Ana Sofia; Vital, Márcia; Cunha, Mariana; Maia Matos, Mário; Tonin, FernandaThe consumption of anabolic androgenic steroids (AAS) by competitive and non-competitive bodybuilders is relatively common, yet there is diverse and often conflicting evidence on the short- and long-term side-effects of AAS abuse. We aimed at assessing the impact of AAS use (supraphysiological doses/schedule) on adult bodybuilders by means of a broad systematic review and evidence gap mapping (CRD42023401245). ...
Profile of gym-goers who do not use performance-enhancement substances
Tavares, Ana Sofia; Carolino, Elisabete; Teques, Pedro; Calmeiro, Luis; Serpa, SidonioIntroduction: Currently the use of prohibited performance-enhancing substances (PES) in fitness and gym settings is a public health concern as adverse health consequences are emerging. Understanding the characteristics of gym-goers who do not use these substances could lead to an important complement to the ongoing research about risk factors for PES use. This study aimed to identify the profile of PES non-use ...
Portuguese gym-goers versus performance enhancing substances: what do we know?
Tavares, Ana Sofia; Carolino, Elisabete; Teques, Pedro; Calmeiro, Luís; Serpa, SidónioThe use of prohibited performance-enhancing substances (PES) in gyms is a public health concern due to emerging adverse health effects. While psychological and social factors (intentions, attitudes, and beliefs) influencing PES use are known, understanding reasons for non-use is crucial. Demographic factors like being male, having less education, being unemployed, training frequently, and bodybuilding are linke...
