Water- the forgotten nutrient: revisiting its role in health and disease
INTRODUCTION: Water intake has arguably been one of the least-studied topics in nutrition science and is often described as the ‘forgotten nutrient’. Despite its importance, it has been largely overlooked in dietary guidance. DEVELOPMENT: A Recommended Dietary Allowance for water has yet to be established. Adequate Intake guidelines of 3.7 and 2.7 L of water per day have been suggested for sedentary adult men and women (> 18 y), respectively. Even though these values are based on population consumption data, they are also supported by recent scientific evidence. Body fluid balance is regulated by fluid balance homeostatic mechanisms. Arginine vasopressin (AVP; also known as anti-diuretic hormone) is regulated by osmoreceptors and baroreceptors and among many functions, it mainly reduces urinary output. It has been suggested that thirst might be an adequate signal for water intake when the body is in a deficit. However, inadequate water intake and underhydration can occur in the absence of thirst. There are many deleterious health effects related to elevated AVP and underhydration. Low water intake and elevated AVP significantly and negatively impact cardiovascular health, mood, kidney function, glucose regulation, chronic disease development, accelerated aging, and increased mortality. Water intake is particularly important during physical activity, especially in warm environments. Replacing fluids lost through sweating is essential for maintaining fluid and electrolyte balance during thermoregulation. CONCLUSION: Increasing water consumption through palatable non-sugar-sweetened beverages represents a simple, cost-effective strategy with the potential to produce sustained improvements in population health.

[English original] Anthropometric, aerobic and muscle power profile of young Costa Rican basketball players
The purpose of this study was to describe an anthropometric, aerobic and muscle power profile of young Costa Rican basketball players according to sex, play positions and age. The assessment was carried outa on 99 young players (43 women and 56 men; 18 guards, 51 forwards and 30 centers; 42 in the U16 category and 57 in the U18 category) from eight different teams. The sports experience of the players was 6.5 ± 3.1 years. The following parameters were assessed: height, weight, body mass index, skeletal muscle mass and body fat percentage, countermovement test (CMJ) and Yo-Yo Intermittent Recovery Test Level I. The main results showed significantly higher values in men than in women in terms of weight, height, skeletal muscle mass, distance covered in the yo-yo test, VO2max, height in CMJ and in flight time. Body fat percentage was higher in women than in men. Centers showed significantly higher height, weight and body fat percentage than other play positions. Guards and forwards covered more meters in the yo-yo test and showed higher VO2max than centers. No significant differences were found between the U16 and U18 categories in any variable. Regression models showed the influence of weight, body fat percentage, skeletal muscle mass and age on VO2max and CMJ. In conclusion, these indicators varied according to the sex and play position of the players. Additionally, this information will be useful for processes of promotion, development and training design of youth basketball in Costa Rica.

[English original] Full study of characteristics of morphological adaptations in response to chronic exercise across musculoskeletal tissues: a systematic review
To date, there is no systematic review that summarizes the morphological adaptations of the musculoskeletal system in response to chronic exercise. This systematic review selected original articles published in English between 2000 and 2020, with a clear exercise intervention and presenting a morphological change in the tissue under study, and covering human participants irrespective of age, gender or health condition. In total, 2819 records were identified. After removal of duplicates, title and abstract screening and full-text review, 67 records were included in the final analysis (6 for inter-vertebral disc, 6 for cartilage, 36 for bone, 2 for ligament, 9 for tendon and 7 for muscle). The most used interventions were aerobic, resistance, and plyometric exercise. Population ranged from children and healthy active people to individuals with a health condition. In conclusion, as a response to chronic exercise there are morphological adaptations in the tissues of the musculoskeletal system which vary from increased stiffness to an increase in cross-sectional area. Although tissues can adapt, several questions still linger, such as optimal dose and type of exercise, whether adaptations can occur in an injured tissue, and functional implications of these adaptations. Future research should address these questions.

Is thirst sufficient as a mechanism for achieving euhydration? A narrative review
The role of thirst perception for keeping hydric balance, both during and after exercise, has been extensively studied. However, the way to assess it and the effectiveness of the existing instruments are areas that still require further research. The objective of this review is to integrate, in a general way, the information available in the literature on the functioning of the thirst mechanism as a response to dehydration during and after exercise. The physiological mechanisms and their responses during and after exercise are explained. In addition, a description of the instruments available in scientific literature is included, together with their weaknesses and strengths, and a series of as yet unanswered questions in this area are raised. This review presents the theoretical aspect of thirst mechanisms, and discusses the scientific studies that support or refute the behavior of these mechanisms in exercise. Finally, a summary is made of the major conclusions drawn from the scientific literature on thirst as a sufficient mechanism to prevent dehydration both during and after exercise.

Compared study of physical activity, sedentary lifestyle and physical self-concept among chilean adolescents with and without special educational
The objective of the study was to compare the level of physical activity (PAL), sedentary lifestyle and physical self-concept in school students of both genders in the region of Araucanía (Chile) with and without Transitory Special Educational Needs (TSEN). The research has a quantitative approach with a non-experimental, cross-sectional design and a compared descriptive scope. The assessment included 43 adolescents between 15-17 years old in the region of Araucanía, with and without TSEN. The team applied the international physical activity questionnaire (IPAQ), the physical self-concept questionnaire (CAF) and the adolescent sedentary activity questionnaire (ASAQ). The main results showed that, as related to PAL, the majority of students without TSEN were situated in the medium level, while those with TSEN were situated in the lower level with significant differences between them. Concerning the sedentary lifestyle, both groups showed a highly sedentary behavior, without significant differences and with a 3415 minute average. For physical self-concept, no significant differences were observed in the comparison. The conclusion is that, while adolescents with TSEN showed a physical self-concept and sedentary behavior similar to adolescents without TSEN, their levels of physical activity were significantly lower, so that the role of the Physical Education teacher can be key in the modification of habits in physical activity and sports in adolescents with TSEN, as well as in the organization of a higher offer of inclusive sports or physical instances.

Mental, physical or combined practice in motor performance and learning: a meta-analytical response
Practice is a key element in the process of acquiring motor skills, because it facilitates learning. This practice can be of either of two types—physical or mental. The objective of the present study is to determine the extent of effect of physical practice (PF), mental practice (PM) and combined practice (PC) throughout the process of acquisition and retention in the performance of motor skills, using a meta-analytical approach and the analysis of possible moderating variables. The random effect model was used to calculate the extent of the effect (TE). A total 24 studies were included, and a total of 150 TE was obtained, separated in four groups. In the phase of acquisition, it was found that the PF (TE = 1.75; n = 36; IC = 0.96,3.55; Q = 113; I2 = 92%), the PM (TE = 0.80; n = 36; IC = 0.50,1.09; Q = 108; I2 = 74%) and the PC (TE = 1.78; n = 22; IC = 1.39,2.18; Q = 167; I2 = 79%) improved their performance; in addition, the control group (GC) improved the performance in acquisition (TE = 0.18; n = 22; IC = 0.02,0.35; Q = 19; I2 = 0%). A meta-regression indicated that only physical, mental and combined practice significantly predict the TE. In the retention phase, neither the PF (TE = -0.97; n = 9; IC = -0.41,0.02; Q = 12; I2 = 29%), the PM (TE = 0.62; n = 6; IC = -0.19,1.45; Q = 22; I2 = 83%), the PC (TE = -0.01; n = 14; IC = -0.26,0.25; Q = 23; I2 = 46%) or the GC (TE = -0.15; n = 5; IC = -0.75,0.44; Q = 11; I2 = 66%) showed a significant change. Possible moderating variables were analyzed. The results suggest that the three types of practice improve performance in the acquisition phase, while in the retention phase they help to keep what has been learned. The PM does not replace PF; however, PF can be complemented with PM under some conditions.

Physical activity, time in front of the computer, sleep hours and body mass index in adolescents in times of pandemic
The COVID-19 pandemic has resulted in enormous changes in people’s daily life activities. The levels of physical activity have decreased, time in front of the computer has increased, and this has caused physical inactivity and sedentary lifestyles in schoolchildren. The authors’ objective was to determine the direct relationship between physical activity, time in front of the computer and sleep hours, on the one hand, and, on the other, body mass index in adolescents of ages 12-17 in the region of Puno, Peru. The approach used is quantitative, and the type of research undertaken is non-experimental with a cross-cutting design. An intentional non-probabilistic sample was applied, consisting of 485 adolescents (241 females and 224 males) with an average age of (14.14 ± 1.34). The instruments used were the physical activity questionnaire, the time in front of the computer with Cronbach’s Alpha reliability analysis of .918 and .862, plus the self-report of body weight and standing height. Results: 20.65% of females show a low physical activity level, while high physical activity is predominant in 9.87% of males; 14.19% of females spend more time in front of the computer during the week (6-7 hours per day), in contrast with males (12.26%); 23.66% of females show overweight and 5.81% of them show obesity, while for males these percentages are 20% and 3.23%. An inversely proportional Spearman Rho correlation of -0.167 and p < .01 exists. The conclusion is that the body mass index increases with less physical activity.

Perception of quality of life in chilean para-athletes and non-athletes with brain injury
Quality of life (QOL) and physical activity are relevant aspects in the health of the population, and the latter has a positive impact on people with disabilities. For this reason, the objectives of this study were to compare the characteristics and identify the association between the domains of QOL perception between a group of people with brain injury who practice soccer, para-athletes (PD) and non-para-athletes with brain injury (NPD), as well as to determine if there are differences in the perception of QOL according to the different sports classes (FT1, FT2 and FT3). The study was carried out in Chile, where the WHOQOL-BREF questionnaire was applied to determine the QOL of participants. The results identified a positive and significant relationship between the different domains of QOL (p < .001, r = .44 - .67). In addition, a better perception of QoL was observed in the PDs (p < .001, TE = 1.18, large) compared to that reported by the NPD group. On the other hand, no significant differences between domains were obtained for the different sport classes in the PD group. These data reinforce the idea that sport practice influences social participation and perception of QoL in PD with brain injury. The joint development of the factors associated between health and socioemotional well-being could collaborate in the consolidation of sports practice and physical activity, which, in turn, are beneficial for people with disabilities, as proposed by the Sustainable Development Goals in their work agenda foreseen for the year 2030.

[English original] Accessibility perception of chilean para-athletes, road to Santiago 2023
The objective of this research is three-fold: 1) to understand Para-athletes’ perceptions on accessibility regarding Santiago 2023 Parapan American games’ future venues, 2) to establish differences in perception due to the origin of the disability, and 3) document alignment, if any, with athletes with high support needs (AHSN). This research is a two-phased quantitative cross-sectional study, which at the first stage developed the “Para-athletes Perception on Accessibility Survey” (PPA-D) and, at the second stage, the survey was applied to 96 Chilean Para-athletes (77.8% men, mean age = 31.0 ± 11.6 years old). The test obtained a validation coefficient of = 0.96. Regarding the sample characteristics, 16.6% corresponded to participants with visual impairment, 35.1% were AHSN, 51.5% were linked to high-level competition, and 59.3% travelled on their own to their training sessions. A negative perception of accessibility was found, mainly concerning minibuses, elevators, and restroom spaces, affecting mostly AHSN with visual impairment (F1.101 = 14.01, p = .0003). We conclude that it is important to address gender, disability, and AHSN gaps to guarantee equitable participation under a framework of the law and social rights.

Physical activity for adults and senior adults: The institutional program of Universidad de Costa Rica
The purpose of this article is to present the evolution of the Human Movement Module (HMM) of the IPSA and the impact this has had on the attention to senior adults (SA). The first university for senior adults originated in Toulouse, France, in the early 70’s, and it is thanks to Dr. Alfonso Trejos Willis that the Institutional Program for Adults and Senior Adults (IPSA) has existed for 35 years at Universidad de Costa Rica. Based on the premise of “education throughout life,” the University offers to Costa Rican citizens a valuable return in opening opportunities to this age group. Over time, the Program underwent a transformation in response to the needs and social changes of the Costa Rican population, in which the importance of keeping adults and senior adults active is expressed. As a result, the Human Movement Module (HMM) emerged, headed by facilitators that offer their courses pro bono. In this module, the courses were adapted to a virtual format in order to make them available to the senior adult population, a group that has been considered at risk due to the COVID-19 pandemic.

[Spanish translation] Unique features of physical education – a look at evaluation
Evaluation of learning is integrated into all curricular components, including Physical Education, which deals with knowledge related to bodily culture, such as play and games, gymnastics, dancing, sports, wrestling and adventure activities. Seeking to better understand the characteristics of evaluative activities developed by physical education teachers, a descriptive study with a qualitative approach was carried out in the municipal territory of Marechal Cândido Rondon, State of Paraná, Brazil. The data were obtained by applying a semi-structured interview, which was considered valid in terms of language clarity, practical relevance and theoretical significance. Data collection took place between August and October, 2017, at school facilities. The data were analyzed qualitatively through the content analysis technique, and classified into evaluation functions, number of evaluations carried out per quarter, instruments/procedures, evaluation criteria and difficulties that came up during the evaluation process. The results showed that the evaluation process was both formal and informal, and was carried out through tests and papers, presented as a requirement of the school and focused on examining the appropriation of theoretical or conceptual knowledge, as well as through observation by the teacher. They were focused on analyzing the motion and technical evolution of each student, in addition to assessing their participation and involvement in the classroom. Generally speaking, the evaluation developed by the teachers sought to respond to the determinations of the school system and the unique features of knowledge related to body culture that are approached in this discipline.

[Spanish translation] Understanding the dimensions of athlete brand authenticity
The management of an athlete brand is challenging due to the complex nature of athlete career and life. Striving to maintain brand authenticity will promote long-term sustainability of the brand. The purpose of the study is to determine possible factors that contribute to athlete brand authenticity and help athletes to develop their brand more authentically. To understand the concept of athlete brand authenticity, a systematic literature review was conducted on various electronic databases. The study opted the five-step stages of the framework for this systematic review. A total of 76 attributes were identified from past studies that analyzed the attributes of brand authenticity for various brands. After merging interrelated attributes, the final number of unique attributes was 23. These attributes were distributed among three major themes: on-field activities, off-field activities and marketing activities of an athlete. The study finds brand authenticity to be a multi-dimensional and complex process that endures for longer extensive periods of an athlete’s career. The current study also highlights the complications related to an athlete brand that occur when establishing athlete brand authenticity. Therefore, this study provides an opportunity to refine athlete brand authenticity further within the discussed domains.

Data base of Effect of aerobic exercise on cardiorespiratory capacity in survivors of covid-19: meta-analysis
The purpose of this study was to quantify the effect size (TE) of aerobic exercise on cardiorespiratory capacity in survivors of the COVID-19 disease caused by the SARS-CoV 2 virus. Two data bases (EBNSCO host and PubMed) were reviewed over the months of August through November, 2021. A total 142 656 potential articles were reviewed and, after applying several filters, 9 studies that met the requirements for inclusion were included. The random effect model was used. A first meta-analysis that was biased (according to Egger test) obtained 12 TE. After identifying and eliminating groups with an extreme TE, a corrected, unbiased model was obtained with 7 studies and 9 TE was obtained, where it was found that aerobic exercise has a significant, positive and large-magnitude effect on the cardiorespiratory condition on survivors of the COVID-19 disease (TE = 0.849; IC95%: 0.715 – 0.9 82; Q = 7.13; p = 0.522; I2 = 0.87%; Egger p = 0.205). Interventions with aerobic exercise foster an improvement in cardiorespiratory capacity in patients who survived COVID-19. Two studies applied aerobic exercise only, whereas the other seven combined aerobic exercise with strength exercise and other modes. In all cases, a significant TE was obtained. Finally, these results were relatively homogeneous, with no evidence for the influence of possible moderating variables.

Data base of Relationship between process- and product-oriented assessments of actual motor performance: a meta-analysis
Motor performance is often assessed in two different ways. The first of them focuses on how the skill is carried out, whereas the second records the product obtained after execution. While both are widely used, the relationship between them is not clear. The objective of the present study is to determine the relationship between the results of process- or product-oriented tests that are used to measure actual motor performance, and to examine possible moderating variables through the meta-analytic technique. In order to sum up the products, the random effect model (REML) was used and the effect size (TE) of the correlation was calculated. A total seven studies met the criteria for eligibility, and a total 37 TE were obtained. It was found that a significant and positive relationship exists between process- and product-evaluated performance (TE = 0.466; IC95% = 0.391, 0.541; p < .001; n = 37; Q = 78.68; p < .001; I2 = 60.17%). Age and skill type were analyzed as possible moderating variables. The results suggest that a relationship exists between process- and product-oriented assessments of actual motor performance, while age and the type of skill have no influence on that relationship.

Physical activity in Costa Rican urban population and its relationship to socio-demographic and anthropometric patterns
The objective of this study was to describe the amount of physical activity carried out by Costa Rican urban population and to determine its relationship to socio-demographic and anthropometric variables. A representative sample of Costa Rican urban population, made up by 798 individuals, was analyzed. The physical activity data (displacement, free time and total) were taken through the International Physical Activity Questionnaire (IPAQ). Participants were classified as active or inactive according to the internationally recommendation of physical activity. 37.1% of participants did not meet the recommendations. It was also observed that the time of physical activity was significantly longer (p< .001) in men (535.3 vs. 371.3 min/week) in younger people (584.3 min/week in the 15-19 years old group vs. 309.2 min/week in the 50-65 years old group) and in people that were not overweight (521.3 vs. 411.7 min/week). The waist circumference was significantly lower in active people (90.6 vs. 94.1 cm, p < .011), and active men also showed a lower neck circumference (38.2 vs. 39.6 cm, p < .001), lower weight (75.7 vs. 79.3 kg, p = .025) and a lower body mass index (26.1 vs. 27.9 kg/m2, p = .004). These results could be used to raise awareness on the need for improvement in the implementation of global policies and practices to promote physical activity.

[English original] Morphological adaptations in response to chronic exercise across musculoskeletal tissues: a systematic review
Level of motor coordination in children participating in the integral sports schools program of chile’s sports ministry
In recent years, it has been identified that low general motor coordination affects low participation in instances of free play, organized and free sports activities. In turn, a better motor domain is related to a low level of sedentary lifestyle and therefore a higher level of physical activity. Goal. To compare the level of general motor coordination of boys and girls participating in the Sports Initiation component of the "Comprehensive Sports Schools" program of the Chilean Ministry of Sports ("Learning in Movement" since 2019) with those of a control group, in different regions of Chile. . Methodology. In relation to the sample, 417 boys and girls were evaluated (341 EDI group and 76 control group) from eight regions of the country (Antofagasta, Coquimbo, Valparaíso, O`Higgins, Metropolitana, Bío - Bío, Araucanía and Los Lagos) whose ages fluctuated between 6 and 11 years of age. To collect information, the 3JS instrument was used, consisting of seven tasks (3 for locomotion and 4 for object control). Results. Males have better performance than females in general motor coordination. By grouping the test items according to the type of coordination, they also outperform the ladies in locomotion and object control. Boys and girls from the Los Lagos region perform better in six of the seven tests. The boys and girls who participated in the program (EDI group) obtained better results than the control group, in five of the seven tests. Conclusion. Boys outperform girls in locomotor coordination and object control tests, as well as in general motor coordination scores. The boys and girls of the EDI program outperform their peers who do not participate in these instances, evidencing a greater difference in tests that require throwing, precision and obstacle draw.

Data base of Maximum heart rate prediction equations fail key external validation test
Maximum heart rate (HRmax) equations have been used due to their simplicity and practicality, in comparison with stress tests. However, the best known “220-age” equation presents: low reliability and deviations of up to 12 beats/min. New formulas have been proposed, but these have not been correctly validated. The purpose of this study was to validate 7 prediction equations using an independent database. A database of 634 subjects (474 ​​men and 160 women) aged 18-85 years, obtained as part of a health service developed at the University of Michigan between 1990-1992, was used. Subjects performed a VO2max test on a treadmill, following a free protocol. The linear regression technique was used, in which the appropriate equations were those that met the 2 hypotheses: slope=1 and constant=0. According to the results, none of the equations analyzed for the entire sample accepted both hypotheses. When carrying out the analysis divided by sex, six of them met the two hypotheses for women, but none for men; and when performed divided by age group, 4 of the equations mee the hypotheses for the group of people with 40 years or younger, but not for the group of people over 40 years. HRmax. seems to be difficult to predict using a single equation, hence it is recommended that when a valid measure of this variable is needed, a stress test should be used.

The Exercise and Sports Science Australia position statement: Exercise medicine in cancer management
Since Exercise and Sports Science Australia (ESSA) ﬁrst published its position statement on exercise guidelines for people with cancer, there has been exponential growth in research evaluating the role of exercise pre-, during and post-cancer treatment. Design and Methods: The purpose of this report is to use the current scientiﬁc evidence, alongside clinical experience and exercise science principles to update ESSA’s position statement on cancer-speciﬁc exercise prescription. Results: Reported in this position statement is a summary of the beneﬁts accrued through exercise following a cancer diagnosis and the strengths and limitations of this evidence-base. An exercise prescription framework is then proposed to enable the application of cancer-speciﬁc considerations for individualisation, speciﬁcity, safety, feasibility and progression of exercise for all patients. Additional speciﬁc exercise prescription considerations are provided for the presence of haematological, musculoskeletal, systemic, cardiovascular, lymphatic, gastrointestinal, genitourinary and neurological disease- and treatment-related concerns, as well as presence of co-morbid chronic disease. Further, we also identify and discuss cancer-speciﬁc pragmatic issues and barriers requiring consideration for exercise prescription. Conclusions: While for the majority, multimodal, moderate to high intensity exercise will be appropriate, there is no set prescription and total weekly dosage that would be considered evidence-based for all cancer patients. Targeted exercise prescription, which includes the provision of behaviour change advice and support, is needed to ensure greatest beneﬁt (as deﬁned by the patient) in the short and longer term, with low risk of harm.

Physical activity in the management of obesity in adults: A position statement from Exercise and Sport Science Australia
This Position Statement examines the evidence for physical activity in weight and adiposity loss, prevention of weight and adiposity gain, and in weight regain in adults, and provides guidance on implications for exercise practitioners. Research evidence indicates that >150 min but preferably 300 min per week of aerobic activity of at least moderate intensity is required to prevent weight and adiposity gain, and at least the upper end of this range of activity to prevent weight regain after weight loss. For meaningful weight and total adiposity loss, a minimum of 300–420 min per week of aerobic activity of at least moderate intensity is required. The evidence around the volume of aerobic physical activity required to reduce central adiposity is emerging, and research suggests that it may be substantially less than that required for weight loss. The impact of high-intensity physical activity and resistance exercise for weight management is uncertain. During consultations for weight management, exercise practitioners should advise that metabolic and cardiovascular health beneﬁts can be achieved with physical activity at any weight, and irrespective of weight change.
