- Detraining and retraining effects from a multicomponent training program on the functional capacity and health profile of physically active prehypertensive older womenPublication . Leitão, Luis; Campos, Yuri; Louro, Hugo; Figueira, Ana Cristina Corrêa; Figueiredo, Teresa; Pereira, Ana; Conceição, Ana; Marinho, Daniel A.; Neiva, Henrique P.Background: Resuming a physical exercise program after a period of cessation is common in older women. Monitoring the responses during this detraining (DT) and retraining (RT) may allow us to analyze how the body reacts to an increase and a reduction in physical inactivity. Therefore, we conducted a follow-up training, DT, and RT in prehypertensive older women to analyze the response to these periods. Methods: Twenty-three prehypertensive older women (EG; 68.3 ± 2.8 years; 1.61 ± 0.44 m) performed 36 weeks of the multicomponent training program (MTP) followed by twelve weeks of DT plus eight weeks of RT. Fifteen prehypertensive older women (CG; 66.3 ± 3.2 years; 1.59 ± 0.37 m) maintained their normal routine. Functional capacity (FC), lipid, and hemodynamic profile were assessed before, during 24 and 36 weeks of the MTP, after 4 and 12 weeks of DT, and after 8 weeks of RT. Results: After 24 weeks of the MTP, only SBP did not improve. Four weeks of DT did not affect lower body strength (30-CS), TC, or GL. Eight weeks of RT improved BP (SBP: −2.52%; ES: 0.36; p < 0.00; DBP: −1.45%; ES: 0.44; p < 0.02), handgrip strength (3.77%; ES: 0.51; p < 0.00), and 30-CS (3.17%; ES: 0.38; p < 0.04) compared with 36 weeks of the MTP. Conclusions: Eight weeks of RT allowed patients to recover the benefits lost with detraining, which after only four weeks affected them negatively, and the systematic practice of exercise contributed to greater regulation of BP since 24 weeks of the MTP proved not to be enough to promote positive effects of SBP.
- Differences between Portuguese and Brazilian Patients with Fibromyalgia Syndrome: Exploring the Associations across Age, Time of Diagnosis, and Fatigue-Related SymptomsPublication . Alvarez, Marcos C.; Albuquerque, Maria Luiza L.; Neiva, Henrique P.; Cid, Luis; Rodrigues, Filipe; Teixeira, Diogo S.; Monteiro, DiogoThe aim of the study was to explore the differences between Brazilian and Portuguese patients with fibromyalgia (FM) syndrome in their experience of fatigue, and to measure differences in the perception of fatigue as a function of age and duration of the diagnosis. In total, 209 Portuguese women aged between 21 and 75 years (M = 47.44; SD = 10.73) and 429 Brazilian women aged between 18 and 77 years (M = 46.51; SD = 9.24) were recruited to participate in the present study. Participants completed the Multidimensional Daily Diary of Fatigue-Fibromyalgia-17 items (MDF-Fibro-17), a specific tool to measure the level of five components of FM-related fatigue. Results showed greater perception of all the components of fatigue in the Brazilian sample. No significant differences were found related to age and duration of FM diagnosis. The multifaceted nature of FM and cultural differences suggests that individualized treatment programs may be necessary to reduce fatigue-related symptoms in patients with this syndrome.
- Exploring the relationship between fibromyalgia-related fatigue, physical activity, and quality of lifePublication . Alvarez, Marcos C.; Albuquerque, Maria Luiza L.; Neiva, Henrique P.; Cid, Luis; Rodrigues, Filipe; Teixeira, Diogo S.; Matos, Rui; Antunes, Raúl; Morales-Sánchez, Verónica; Monteiro, DiogoThe symptoms of fibromyalgia are varied, including general muscle pain and pain at specific points (also called tender points), excessive fatigue, anxiety, depression, and some psycho logical problems that can have a negative impact on quality of life. Physical activity is a widely used option by health professionals to alleviate the effects of this syndrome. However, there is no clear information on the possible mediating role of physical activity in the relationship between fibromyalgia-related fatigue and quality of life. Therefore, this study aims to evaluate the relationship between fibromyalgia-related fatigue and quality of life, and to investigate the mediating role of physical activity in patients with this syndrome. Methods: In a cross-sectional study, 237 Portuguese women aged 28 to 75 years (M = 49.12; SD ± 8.87) and 117 Brazilian women aged 20 to 69 years (M = 46.72; SD ± 8.38) were recruited to participate in this study. These patients completed three valid and reliable questionnaires related to the assessment of fibromyalgia-related fatigue (MDF-Fibro-17), physical activity (IPAQ), and quality of life (SF-36). Results: Both samples had scores above the midpoint for all dimensions of fibromyalgia-related fatigue and scores below the midpoint for quality of life. Physical activity had no mediating effect in either sample, as the total indirect effect was not significant. Conclusions: Physical activity does not mediate the relationship between fatigue and quality of life. However, the results also show that the fatigue dimensions associated with fibromyalgia had a negative and significant association with physical and mental health indicators in both samples. Thus, patients with FM with higher scores on fatigue-related symptoms might suffer more from physical and mental health, both of which are related to quality of life.
- Neuromuscular assessment of a stand-up paddle strokePublication . Freitas, João; Conceição, Ana; Šťastný, Jan; Louro, Hugo; Leitão, Luís; Torres, Diana; Marinho, Daniel A.; Neiva, Henrique P.his study analyzed muscle activity during the stand-up paddle stroke, considering the paddling side and the adjacent and opposing muscles relative to the position of the arms during paddling. Methods: Fourteen male paddleboarders performed three trials covering 195 m in which surface electromyography of the upper trapezius, biceps brachii, triceps brachii, tibialis anterior, and gastrocnemius medialis were recorded (four-cycle strokes on each side). The data were processed according to percentage of maximum voluntary contraction (% MVC). The MVC activation values (µV) for each muscle were then calculated and presented as percentage MVC (% MVC). Results: The recovery phase accounted for 60% of the paddle cycle, while the pull phase represented 39%. During right-side paddling, higher % MVC was found in the opposite-side upper trapezius (24.35%, p < 0.01) during the pulling phase and in the adjacent biceps brachii (8.36%, p < 0.03) during the recovery phase. In left-side paddling, greater % MVC was found in the opposite-side upper trapezius (27.60%, p < 0.01) during the pulling phase and in the opposite-side triceps brachii (42.25%, p < 0.04) during the recovery phase. Furthermore, the pulling phase exhibited higher MVC in the opposite-side upper trapezius compared to the recovery phase, both in the right-side (24.35%, p < 0.03) and left-side (27.60%, p < 0.01) paddling. Conclusions: these findings help establish the muscular activity of both sides of the paddling technique and the differences between the upper and lower limbs.
- Sprint performance determinants in high level young swimmersPublication . Matos, Carolina L.; Conceição, Ana; Louro, Hugo; Neiva, Henrique P.; Sobreiro, Pedro; Viana, Bárbara L.; Marinho, Daniel A.Background: Identifying and evaluating the variables that influence performance are essential for obtaining excellence in sport. Objective: This study aimed to identify which parameters have the most influence on the 50 meters freestyle time in young competitive swimmers. Methods: One hundred and eighty-four high-level swimmers (males, n=92: 14.60±0.56 years; females, n=92: 13.53 ± 0.54 years) with 468±66 FINA points in the 50 meters freestyle short course participated in this study. Age, height, body mass, wingspan, stroke rate, stroke length, stroke index, turning time (5 m + 10 m), horizontal jumping, and medicine ball throwing were assessed. The swimming performance was assessed in a 50 meters freestyle time trial at maximum speed in a 25 meters swimming pool. Multiple regression was performed to assess the relationship between one dependent variable (50 meters freestyle time) and independent variables. Results: The results showed significant differences between both the genders. In male swimmers, only the turning time and the horizontal jump were significant (r2 =0.8819; p<0.001), while females, besides the same variables, presented significant results in terms of height, body mass, stroke length, and stroke index (r2 =0.9013; p<0.01). Conclusion: In conclusion, in young male swimmers, the turning time and the horizontal jump contributed significantly to the 50 meters freestyle swimming performance, and in young female swimmers, the main contributors were the turning time, horizontal jump, height, body mass, stroke length, and stroke index.

- A systematic review for stand-up paddle: a review in stand-up paddlePublication . Freitas, João; Conceição, Ana; Louro, Hugo; Forte, Pedro; Marinho, Daniel A.; Neiva, Henrique P.The goal is to investigate how the length and height of passes impact a team's performance in national championships. A predictive model will be developed to analyse the success of different pass characteristics, including short, medium, and long length and ground, low, and high height. The model will be based on the points earned and will determine which combination of pass characteristics is most effective. Objective Therefore, this systematic review aims to identify and synthesize the external and internal parameters commonly used to evaluate SUP performance under different test conditions. Methods The search was conducted in multiple scientific databases (Google Scholar, MEDLINE/(PubMed), Science Direct, and Web of Science) and was completed on January 31, 2022, using the following keywords: “stand up paddle,” “stand up paddling”, and “stand up paddle boarding.” Results Twenty-one articles were selected, involving a total of 238 subjects at both the competitive and recreational levels. SUP athletes have increased muscle mass, decreased body fat percentage, and used more efficient paddling techniques, highlighting the importance of equipment evaluation in improving athletic performance. Conclusion More research is needed to improve the performance and expand the culture of SUP. The integration of specific technologies can help to understand better the variables that affect performance outcomes.
- The multidimensional daily diary of fatigue-fibromyalgia-17 Items (MDF-Fibro-17): evidence from validity, reliability and transcultural invariance between Portugal and BrazilPublication . Álvarez, Marcos C.; Albuquerque, Maria Luiza L.; Neiva, Henrique P.; Cid, Luis; Teixeira, Diogo S.; Rodrigues, Filipe; Monteiro, DiogoThe Multidimensional Daily Diary of Fatigue-Fibromyalgia-17 (MDF-fibro-17) is an instrument that measures the different components of fibromyalgia-related fatigue symptoms. The current study aims to examine the factor structure of the MDF-fibro-17 in a sample of Portuguese and Brazilian patients diagnosed with fibromyalgia. Additionally, a cross-cultural analysis was carried out on these samples to understand the multidimensional complexity of examining the different dimensions of fatigue in patients with different cultural backgrounds and how fibromyalgia impacts patients with this syndrome. A confirmatory factor analysis was performed to examine the psychometric properties of the measure. Additionally, a multigroup analysis was carried out on the samples of these two cultures to examine measurement invariance. In total, 209 Portuguese women aged between 21 and 75 years (M = 47.44; SD = 10.73) and 429 Brazilians women aged between 16 and 77 years (M = 46.51; SD = 9.24) participated in this study. The results revealed that the measurement model provided an acceptable fit to the data in both the Portuguese and Brazilian samples, also displaying acceptable convergent and discriminant validity. In addition, the model showed acceptable internal consistency and was invariant between cultures. In sum, the MDF-fibro-17 is a valid measure that offers a unique assessment of fatigue symptoms in Portuguese and Brazilian women with fibromyalgia.
- Trainer‐exerciser relationship: the congruency effect on exerciser psychological needs using response surface analysisPublication . Rodrigues, Filipe; Pelletier, Luc G.; Rocchi, Meredith; Neiva, Henrique P.; Teixeira, Diogo S.; Cid, Luis; Silva, Luis; Monteiro, DiogoPerceptions of fitness trainers' need-supportive and need-thwarting behaviors have been shown to impact exercisers' psychological need satisfaction and frustration. Currently, it is unknown whether an agreement or disagreement between exercisers' and fitness trainers' reported perceptions of these behaviors leads to the satisfaction and/or frustration of psychological needs. Based on self-determination theory, the present study examined the effect of congruency between fitness trainers' and exercisers' perceptions of need-supportive and need-thwarting interpersonal behaviors on basic psychological need satisfaction and frustration. A sample of 130 fitness trainers (43 females; Mage = 31.58 ± 7.65) and a total of 640 gym exercisers (350 females; Mage = 34.23 ± 11.59) participated in this study. Findings suggested that the majority of fitness trainers tended to over-report their use of need-supportive behavior and under-report their need-thwarting behaviors. Results showed that when there was congruency between fitness trainers' reported use and exercisers' perception of interpersonal behaviors, basic need satisfaction tended to increase. This effect was greater for exercisers that rated their respective fitness trainer high on relatedness support. Fitness trainers should be self-aware of their interpersonal behaviors when engaging with exercisers and interventions based on self-determination theory could serve as a promising avenue to improve the quality of exercisers' experience.
- Understanding exercise adherence: the predictability of past experience and motivational determinantsPublication . Rodrigues, Filipe; Teixeira, Diogo S.; Neiva, Henrique P.; Cid, Luis; Monteiro, DiogoBackground: An unresolved debate lingers over the effect of past behavior on motivational patterns and future behavior stability in the exercise context. Theorists argue that past behavior has a residual effect on future behavior; however, empirical studies have shown that past behavior displays significant power in predicting behavior recurrence in the future. The present research aimed to examine the effect of past behavior and motivational determinants on future exercise adherence. Methods: Data from 437 Portuguese gym exercisers (female = 235; male = 202) aged between 18 and 53 years (M = 31.14; SD = 9.47), with exercise experience ranging from 6 to 12 months (M = 9.41; SD = 1.33) were considered for research. Participants completed a multi-section survey measuring interpersonal behaviors, basic psychological needs, behavioral regulations, and intentions. Data from past behavior and future exercise adherence were collected using computerized records of their attendance at the gym. Results: Positive and significant correlations paths were evidenced among perceived supportive behaviors, needs satisfaction, autonomous motivation, intentions and future exercise adherence. Similar results were presented among perceived thwarting behaviors, needs frustration, and controlled motivation. Regression paths showed that perceived supportive behavior, basic needs satisfaction, and autonomous motivation displayed positive and significant effects on future behaviors; thus, past behavior displayed the highest coefficient on future exercise adherence. Fitness professionals should aim at creating supportive environments, thus, improving the likelihood of being perceived by exercisers as need-supportive individuals. By doing so, as a result, exercisers would experience increased levels of autonomous motivation and higher rates of future exercise attendance at the gym. Hence, exercisers will gradually form their positive past exercise experience, increasing the probability of engaging in an exercise in the future.
