Effect of acute exercise intensity on cognitive inhibition and well-being: Role of lactate and BDNF polymorphism in the dose-response relationship.

Introduction: There is evidence in the literature that acute exercise can modify cognitive function after the effort. However, there is still some controversy concerning the most effective exercise modality to improve cognitive function in acute interventions. Regarding these different exercise modalities, the dose-response relationship between exercise intensity and cognitive response is one of the most challenging questions in exercise and cognition research. Methods: In this study, we tested the impact of moderate-intensity (MICT), high-intensity (HIIT) exercise sessions, or control situation (CTRL) on cognitive inhibition (measured with the Stroop Test). Thirty-six young college students participated in this study, where a within-subject repeated measure design was used. Results: ANOVA 2×3 demonstrated that HIIT improved the acute cognitive response to a higher degree when compared to MICT or CTRL (p < 0.05). The cognitive improvements correlated with lactate release, providing a plausible molecular explanation for the cognitive enhancement (r < -0.2 and p < 0.05 for all the Stroop conditions). Moreover, a positive trend in wellbeing was observed after both exercise protocols (HIIT and MICT) but not in the CTRL situation. Genetic BDNF single nucleotide polymorphism did not influence any interactions (p < 0.05). Discussion: In this sense, our results suggest that exercise intensity could be a key factor in improved cognitive function following exercise in young college students, with no additional impact of BDNF polymorphism. Moreover, our results also provide evidence that exercise could be a useful tool in improving psychological wellbeing.

Memory Modulation by Exercise in Young Adults Is Related to Lactate and Not Affected by Sex or BDNF Polymorphism.

Currently, high-intensity interval exercise (HIIE) is on the rise compared to moderate-intensity exercise (MIE) due to its similar benefits for health and performance with low time requirements. Recent studies show how physical exercise can also influence cognitive function, although the optimal dose and underlying mechanisms remain unknown. Therefore, in our study, we have compared the effects on visuospatial and declarative memory of different exercise intensities (HIIE vs. MIE), including possible implicated factors such as lactate released after each session and the Brain-Derived Neurotrophic Factor (BDNF) genotype. Thirty-six undergraduate students participated in this study. The HIIE session consisted of a 3 min warm-up, four 2 min sets at 90−95% of the maximal aerobic speed (MAS) with 2 min of passive recovery between sets, and a 3 min cooldown, and the MIE session implies the same total duration of continuous exercise at 60% of the MAS. Better improvements were found after HIIE than MIE on the backward condition of the visuospatial memory test (p = 0.014, ηp2 = 0.17) and the 48 h retention of the declarative memory test (p = 0.04; d = 0.34). No differences were observed in the forward condition of the visuospatial memory test and the 7-day retention of the declarative memory test (p > 0.05). Moreover, non-modifiable parameters such as biological sex and BDNF polymorphism (Val/Val, Val/Met, or Met/Met) did not modulate the cognitive response to exercise. Curiously, the correlational analysis showed associations (p < 0.05) between changes in memory (visuospatial and declarative) and lactate release. In this sense, our results suggest an important role for intensity in improving cognitive function with exercise, regardless of genetic factors such as biological sex or BDNF Val66Met polymorphism.

Different Exercise Types Produce the Same Acute Inhibitory Control Improvements When the Subjective Intensity Is Equal.

Twenty-eight active older people (67.19 ± 4.91 years) who engaged in physical exercise activity twice a week were recruited to participate in a counterbalanced experimental protocol. The participants performed three different exercise sessions on three different days, one based on aerobic activities, one based on strength exercises with elastic bands, and one based on stationary balance games. During all three sessions, they were encouraged to maintain a moderate subjective intensity (5-6 on the RPE10 scale), and their heart rate was recorded. In addition, all of the participants took a digital version of the Stroop test before and after each session. The study aimed to compare the acute cognitive impacts of different types of exercise sessions in older adults. The participants' heart rate differed between the exercise sessions, but they maintained the RPE intensity. There was a significant improvement in inhibitory control (Stroop test) after all sessions, with no differences between exercise sessions. Moreover, some participants agreed to be genotyped to record the single nucleotide polymorphism of BDNF rs6265. There were no differences between Val/Val and Met carriers at the beginning or end of the exercise sessions. The present study showed similar cognitive improvements with different exercise type sessions when the subjective intensity was maintained.

COVID-19 Quarantine Impact on Wellbeing and Cognitive Functioning During a 10-Week High-Intensity Functional Training Program in Young University Students.

Physical exercise can improve cognitive functioning and wellbeing; however, the degree of change in either of these two variables seems to be related to the exercise intensity or type. Therefore, new physical training (PT) programs have been developed to increase exercise efficiency. One such example is high-intensity functional training (HIFT), which has proven to be a time-efficient and highly effective strategy to improve physical fitness. This study analyzed whether HIFT can affect reaction time (RT) and vitality, as well as positive and negative affect. Forty-two college students participated in the study, 21 in the experimental group and 21 in the control group. The experimental group completed 10 weeks of training, five of which were supervised, and the remainder consisted of online training during the COVID-19 quarantine. Participants were evaluated at the beginning, at the end of the 5 weeks of supervised training, and after the 5 weeks of online training. HIFT improved RT without changes in psychological wellbeing during the entire period of training supervised and online. Therefore, during the HIFT program, the quarantine situation did not adversely affect this population's wellbeing, but it did negatively affect adherence to the training program.

The maturity status but not the relative age influences elite young football players' physical performance.

Talent identification and selection process in young football is based on coaches' decisions regarding the players' performance at early ages. The aim of this study was to show how the maturity status and the relative age impact on young football players' physical performance and their coaches' efficacy expectations. The physical performance (1RM, Peak power output [PPO], 30-m sprint and t-test) of 118 young football players (U13 to U15; and their coaches' efficacy expectations were assessed. Relative age was calculated according to the players' date of birth within their selection year. The maturity status was estimated as the years from/to their peak height velocity (PHV). Linear regression analyses showed a significant relationship between players' physical performance and their maturity status but not with their relative age. In contrast, the maturity status of players only was associated to the coaches' efficacy expectations in the 1RM and PPO tests, whereas the relative age was a predictor of the coaches' expectations about players' performance in the t-test. These findings may be important for coaches and managers in young football academies since inter-individual differences in the maturity status but not in the relative age are related to physical performance despite the coaches' expectations.

Positive and negative spontaneous self-talk and performance in gymnastics: The role of contextual, personal and situational factors.

The purpose of this study was to analyse whether contextual (perception of motivational climate and positive and negative spontaneous self-talk in sports), personal (positivity) and situational variables (positive and negative spontaneous self-talk employed in competition and precompetitive anxiety) predict performance in a competition of ensembles of rhythmic gymnastics. 258 female gymnasts between ages14 and 20 (M = 15.24, SD = 1.46) participated in the study, completing pre- and post-competition measures. The results of the path-analysis showed that both the task-involving climate and positivity predicted positive self-talk in sport. This predicted self-confidence which, in turn, positively predicted positive situational self-talk in competition. For its part, the perception of an ego-involving climate positively predicted the use of both negative and positive self-talk in sport. Negative self-talk in sports predicted negative situational self-talk in competition and somatic and cognitive anxiety. In turn, cognitive anxiety positively predicted negative situational self-talk. Finally, performance was positively predicted by positive situational self-talk and negatively by negative situational self-talk. These results explain the functioning of spontaneous self-talk at different levels of generality and its relationship with sports performance.

The Coaches' Efficacy Expectations of Youth Soccer Players with Different Maturity Status and Physical Performance.

This study aimed to report possible anthropometrical and physical performance differences between youth soccer players with different maturity status and to report the coaches' expectations, hypothesizing that coaches would expect more from players with advanced maturity. One hundred twenty-two (122) players completed a physical performance battery. Their maturity status was estimated and the coaches' efficacy expectations (CEEs) were assessed. Players with advanced maturation had better physical performance (F = 26.5-73.4; p < 0.01) and their CEEs for strength-related tasks were different according to the maturity status (F = 8.3-10.9; p < 0.01), but not for speed-related tests, nor for their general ability to play soccer. Normalized data showed significant differences between physical performance tests and their respective CEEs within each maturity group, especially in the Post-PHV group. This study confirms the physical advantages of players with advanced maturity while it shows controversial results of how maturation affects the coaches' perceptions and, indirectly, the coaches' identification and selection of talented players.

School Climate, Moral Disengagement and, Empathy as Predictors of Bullying in Adolescents.

Our work aimed to study the relationships between different dimensions of school climate, moral disengagement, empathy, and bullying behaviors (perpetration and victimization). The study sample consisted of 629 students (304 boys and 325 girls) aged 12-14 years (M = 12.55, SD = 0.67). Results showed how different dimensions of school climate predicted moral disengagement, empathy, and victimization, and these, in turn, predicted bullying perpetration. The results show the need to generate favorable educational environments to reduce the levels of moral disengagement and victimization and to increase empathy in students as a strategy to prevent negative consequences related to bullying.

Lack of Correlation between Accelerometers and Heart-Rate Monitorization during Exercise Session in Older Adults.

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. Such "well-programmed" exercise requires efficient and useful tools to measure the activity. The objective of this study is to evaluate the effectiveness of accelerometers to estimate two different intensities of physical exercise in older people. Thirty-eight subjects (64.5 ± 5.3 years) were measured during two different sessions of physical exercise: one moderate in intensity, the other of low intensity. Heart rate and accelerometry were recorded and analyzed. The results showed that the two variables in the physical exercise sessions were not highly correlated, and that accelerometry did not seem useful to assess low-intensity sessions not based on walking.

Effects of a physical activity program on post-bariatric patients: A qualitative study from a self-determination theory perspective.

This study provides an in-depth analysis of the psychosocial benefits that 10 post-bariatric patients (nine female, 31-59 years) perceived from their participation in an exercise program grounded in self-determination theory. Qualitative data were collected through observations and interviews. Participants reported many factors which facilitated basic psychological need satisfaction such as the instructors caring about their opinion, affection, fitness improvement, pain reduction, and knowledge acquisition. These factors were associated with autonomous motivation, enjoyment, intention to be physically active, happiness, and self-confidence. The results suggest that self-determination theory-based exercise programs could be designed to achieve positive outcomes in this population.

Predicting Bullying through Motivation and Teaching Styles in Physical Education.

From the theoretical framework offered by the self-determination theory, the objective of the study was to test a predictor model of bullying behaviors based on the physical education teacher's supportive style, the students' satisfaction of basic psychological needs, and self-determined motivation. A total of 608 students of both sexes, between 11 and 15 years of age, from primary and secondary schools in the province of Alicante (Spain) voluntarily completed questionnaires to measure each of the variables under study. The design of the study was cross-sectional. The results showed that the autonomy supportive style positively predicted the satisfaction of basic psychological needs, which, in turn, positively predicted self-determined motivation towards physical education. The latter negatively predicted bullying perpetration and bullying victimization. The controlling style presented inverse relationships to those of the autonomy supportive style. These results are in line with the positions of the self-determination theory and underline the potential responsibility of physical education teachers in the struggle against bullying, and how, by supporting autonomy and avoiding a controlling style, they can help reduce bullying perpetration and victimization.

Teaching Styles in Physical Education: A New Approach to Predicting Resilience and Bullying.

The main objective of this study was to analyze student-perceived teaching styles' power to predict students' resilience and the emergence of bullying behaviors in physical education class. A total of 537 students of both sexes, between 11 and 15 years of age, from primary and secondary schools in the province of Alicante (Spain), participated in the study. The design of the study was cross-sectional. The results showed that bullying was positively predicted by students' perceptions of a more controlling style and negatively by a greater perception of an autonomy-supportive style in physical education classes. Victimization was negatively predicted by greater resilience and positively by students' perception of a teacher's more controlling style. Finally, the mediation analysis showed that the perception of autonomy support indirectly and negatively predicted victimization, with resilience acting as a mediator. These findings provide useful information for physical education teachers interested in preventing bullying, and have important practical implications about the teaching style recommended for this purpose.

Effect of biological maturation on strength-related adaptations in young soccer players.

Strength training is crucial for soccer players' long-term development at early ages and the biological maturation may influence specific strength-training adaptations. The aim of this study was to propose a strength-training programme for the strength development of pre-pubertal players and to analyse the adaptations to this training programme in players with different maturity status. One hundred and thirty young male soccer players participated in an 8-week strength-training programme consisting of two sessions per week (20-minutes of a combination of plyometric and resistance exercises) which was conducted prior to their normal soccer training. Three maturity groups were defined according to the years from/to their peak height velocity (PHV) as Pre-, Mid- and Post-PHV. Initial differences between the maturity groups were found in anthropometrical (weight and height) and physical performance variables (One Repetition Maximum (RM), Peak Power output (PP), 30-m sprint and T-test). The strength-training programme was beneficial for the three maturity groups (p< 0.05) with general greater improvements for the Pre- and Mid-PHV groups, with large effects in RM, PP and T-test, than for the Post-PHV group (moderate effects). The strength-training programme proposed in the present study seems to be positive for the strength-related development in young soccer players especially for Pre- and Mid-PHV players. The differences in the training adaptations for players with different maturity status suggest the individualization of the training stimulus for the correct long-term development of the players.

Exploring the socio-ecological factors behind the (in)active lifestyles of Spanish post-bariatric surgery patients.

Purpose: Physical activity (PA) is considered essential for the treatment of morbid obesity and the optimization of bariatric surgery outcomes. The objective of this article was to identify the facilitators and barriers that bariatric patients perceived to do PA one year after finishing a PA programme for the promotion of a long-term active lifestyle. This objective was addressed from a socio-ecological and qualitative perspective. Methods: Nine patients (eight women and one man), aged between 31 and 59 years, participated in semi-structured interviews directly following the PA programme and one year after it. A content analysis was carried out to analyze the qualitative data. Results: Weight loss, improvement of physical fitness, perceived competence, and enjoyment were the main facilitators of PA. Complexes related to skin folds, osteoarthritis, perceived unfavourable weather conditions, lack of social support and economic resources, long workdays, lack of specific PA programmes, and other passive leisure preferences were the main barriers to participate in PA. Conclusions: Results highlight the important interplay between personal, social environmental, and physical environmental factors to explain (in)active behaviours of bariatric patients. The findings of this article could be useful for future research and interventions aimed at promoting PA in bariatric patients.

Associations Between Self-Determined Motivation, Team Potency, and Self-Talk in Team Sports.

The current study aimed to evaluate the determinant factors of athletes´ internal positive self-talk that might lead to decreased anxiety and increased performance. The sample consisted of 191 male and female athletes ranging in age from 14 to 35 years old. They played soccer, volleyball and basketball and they were cadets (43%), juniors (29.6 %) and adults (27.4%). Results showed that satisfaction of the basic psychological needs was the strongest predictor of positive self-talk or positive thoughts during competition. Specifically, perception of autonomy was the strongest predictor, because it positively predicted concentration, control of anxiety and instructions, followed by perception of competence, which positively predicted confidence. Finally, team sports coaches should promote perception of autonomy and competence in their athletes, with the aim of enhancing more positive self-talk in competition, which may promote a better performance.

Relative Age Effect, Biological Maturation, and Coaches' Efficacy Expectations in Young Male Soccer Players.

PURPOSE: The talent identification and selection process in young male soccer players is mainly focused on anthropometrics and physical performance, but social factors are also considered in this process. The purpose of this study was to test the existence of the relative age effect and its possible influence on anthropometrics and physical performance and to analyze coaches' efficacy expectations. METHOD: Data for 564 young male soccer players (Mage = 13.7 ± 1.5 years; Mweight = 53.7 ± 11.6 kg; Mheight = 160.2 ± 11.6 cm) included their birth quartile, maturity status, anthropometrics, a physical test battery, and coaches' efficacy expectations. RESULTS: Early-born players were overrepresented (p < .05). Early-born players were not statistically taller, heavier, or better at physical performance (p > .05) when maturation and chronological age were controlled as confounding factors. However, coaches expected more from early-born players (p < .05), and the inferential analysis showed likely to very likely worthwhile differences between the coaches' expectations for players born in the first quartile of the year and those born in the fourth quartile of the year. CONCLUSIONS: Anthropometrical and physical performance variables were not affected by birth quartile, and coaches' efficacy expectations were related to the relative age effect.

The impact of living with morbid obesity on psychological need frustration: A study with bariatric patients.

Guided by self-determination theory, the purpose of this study was to gain an understanding of the previous experiences of living with morbid obesity of 10 postbariatric patients enrolled in a physical activity programme. Qualitative data were collected through interviews and diarized observations. A thematic analysis revealed that participants suffered from health and mobility troubles in their daily life and experienced stigmatization and discrimination in most areas of their social functioning. Participants described how these experiences resulted in the thwarting of their basic psychological needs for autonomy, competence and relatedness. In turn, psychological need frustration contributed to negative consequences such as body image concerns, low self-esteem, anxiety and depression; controlled regulation of their eating behaviour and extrinsic goals; rigid behaviours such as avoiding social situations; and compensatory and self-defeating behaviours such as giving up diet and physical activity regimens and binge eating (i.e., oppositional defiance). This study highlights how living with morbid obesity can impair optimal functioning and well-being via experiences of psychological need frustration.

The Acute Effects of Exercise Intensity on Inhibitory Cognitive Control in Adolescents.

Adolescence is an important stage for brain maturation. There are many studies of exercise-cognition relations, but there is still a lack of knowledge about the impact of combining different intensities of exercise on adolescents' cognitive responses. The main objective of this study was to analyze the effect of three physical education sessions (based on Zumba dance) of different intensities (no exercise, predominantly light intensity, and predominantly vigorous intensity) on the inhibition response (measured with the Stroop test) in adolescents. Forty-four adolescent students (age 16.39 ± 0.68) completed a Stroop test before and after the three different physical education sessions. The results show than the predominantly vigorous session represented the strongest stimulus to increase cognitive inhibitory control. This means that the cognitive effect of exercise can be conditioned by exercise intensity and implies the need to control exercise intensity in physical educational programs for adolescents.

Evaluación de las propiedades psicométricas de la escala de satisfacción de las necesidades psicológicas básicas en general con adultos españoles / Evaluation of the psychometric properties of the scale of satisfaction of basic psychological needs in general with spanish adults

Los postulados de la teoría de la autodeterminación defienden que para lograr una motivación más positiva y el bienestar es necesario satisfacer las necesidades psicológicas básicas: autonomía, competencia y relación. Para medir la satisfacción de estas necesidades en la vida, se ha creado la Escala de Satisfacción de las Necesidades Psicológicas Básicas en General (BNSG-S). Sus propiedades psicométricas han sido analizadas recientemente, aunque sólo con muestras de estudiantes universitarios. El objetivo del presente estudio fue analizar su validez y fiabilidad con una muestra de adultos españoles. En el estudio participaron 399 personas (202 hombres y 197 mujeres), con edades comprendidas entre 18 y 65 años. Los resultados del análisis factorial confirmatorio dieron apoyo a la validez de un modelo reducido de 16 ítems y efecto de método en los ítems negativos. La estructura factorial fue invariante por sexo y edad. Además, se obtuvieron valores adecuados de fiabilidad y estabilidad temporal. El análisis de las evidencias de validez externa mostró que la satisfacción de las tres necesidades psicológicas básicas se asociaba positivamente con la motivación autodeterminada hacia la actividad física y la satisfacción con la vida. Estos resultados dan apoyo a la utilización del instrumento en el contexto español.

The postulates of self-determination theory advocate the satisfaction of basic psychological needs (autonomy, competence and relatedness) to achieve more positive motivation and well-being. The Basic Needs Satisfaction in General Scale (BNSG-S) was created to measure the satisfaction of these needs in life. Its psychometric properties have recently been analyzed, although only with samples of college students. The purpose of the present study was to analyze the validity and reliability of the BNSG-S with a sample of Spanish adults. Three hundred ninety-nine people (202 men and 197 women), aged between 18 and 65, participated in this study. The results of confirmatory factor analysis support the validity of a reduced model of 16 items and a negative-worded method effect. The factor structure was invariant across gender and age. It was also obtained acceptable values of reliability and temporal stability. The analysis of external validity evidences showed that the satisfaction of the three basic psychological needs was positively associated with self-determined motivation towards physical activity and satisfaction with life. These results support the utilization of the instrument in the Spanish context.
