Energy Expenditure Validation of an Exergame Platform: Ring Fit Adventure Use in Adults with Overweight and Obesity.

Objective: This study aims at comparing the energy expenditure (EE) and heart rate (HR) data from Ring Fit Adventure (RFA) with those from indirect calorimetry (COSMED) and a heart rate monitor (Polar FT7). A secondary goal is to evaluate self-reported enjoyment and perceived effort levels. Materials and Methods: Thirty participants (age = 21.8 ± 2.2; body mass index = 31.8 ± 4.4) were recruited for two laboratory visits. The first visit involved baseline measurements. In the second visit, participants performed a 55-minute ad libitum exercise session with the RFA in adventure mode with moderate difficulty. During this session, EE, HR, perceived effort, and enjoyment of physical activity were recorded. Results: Although no statistically significant overestimation of EE was found between the RFA and the metabolic cart, two-way analysis of variance results show a main effect of condition (RFA vs. Polar FT7) on HR (122.8 ± 20.1 bpm and 129.0 ± 18.6 bpm; P = 0.007; ᶯp2 = 0.235). Based on comprehensive statistical evaluations, including the mean absolute percent error, intraclass correlations, typical error of measurement, and limits of agreement, the data suggest that the RFA provides reliable estimates for EE and HR. Overall, participants enjoyed the game considerably (71.3 ± 5.9/80 arbitrary units), and their reported perceived exertion was low. Conclusion: This study underscores that the RFA values are relatively accurate and precise, and thus it can be safely suggested for individuals with overweight and obesity to adopt an active lifestyle.

Sex moderates the associations between physical activity intensity and attentional control in older adolescents.

INTRODUCTION: The relationship between physical activity (PA) intensity and executive functions in older adolescents remains poorly understood. This study aimed to examine the associations between PA intensity, volume, attentional control, and working memory and the moderating effects of sex in older adolescents. METHOD: We analyzed baseline data from 418 participants (211 females, Mage  = 16.5 ± 0.40 years) from the Burn 2 Learn trial. Adolescents wore GT9X Link accelerometers on a non-dominant wrist for 7 days, 24-h·d-1 . PA intensity was expressed as intensity gradient (IG) and moderate-to-vigorous PA (MVPA, Hildebrand cut-points); PA volume was expressed as average acceleration (AvACC). Attentional control was measured with a standard deviation (SDRT) and a coefficient of variation (CVRT) of the reaction time on the incongruent trials of a flanker task. Working memory was expressed as a d prime (a signal discrimination index) on the 2-back task. The moderating effects of sex on the PA-executive functions associations, adjusting for age, BMI z-score, and cardiorespiratory fitness, were tested using multilevel random intercept models. RESULTS: After controlling for AvACC, sex moderated the relationships between IG and incongruent SDRT (B = 0.53, 95% CI: 0.12, 0.94) and CVRT (B = 0.63, 95% CI: 0.22, 1.05; ps ≤ 0.002). Only girls with higher IG showed smaller incongruent SDRT and CVRT (Bs ≤ -0.26, ps ≤ 0.01). IG was not related to working memory. AvACC and MVPA were not associated with attentional control or working memory. CONCLUSION: Our findings reveal a novel association between higher-intensity PA and superior attentional control among adolescent girls.

Listening to Fast-Tempo Music Improves Physical Performance in Recreational Swimmers.

Purpose: To determine whether swimming while listening to fast (140 bpm) or moderate tempo (120 bpm) music enhances physical performance compared to a non-music condition. Methods: Sixteen healthy university students (21.5 ± 2.3 years) with a minimum of one year of experience swimming front crawl were recruited. All completed four testing sessions. In the first session, a graded exercise treadmill test was performed to establish baseline fitness. The next three visits were at the swimming pool and participants were asked to swim as far as possible in 12-minutes (i.e., Swimming Cooper Test) under each of three randomly assigned conditions: 120 bpm (M120), 140 bpm (M140) and a non-music condition (NM). Results: No significant differences were found between conditions for either heart rate (p > .05) or rating of perceived exertion (p > .05). However, differences were found on distance covered (p = .014) between M120 (305.7 ± 19.7 m) and M140 (321.2 ± 19.4 m; p = .035), and on stroke frequency (p = .009) between M120 (48.4 ± 1.8) and M140 (51.6 ± 1.9; p = .028). Conclusion: These results suggest that distance covered and the frequency of strokes per minute were greater when participants were exposed to fast tempo music (M140) compared to moderate tempo music (M120) and a non-music condition (NM) in a 12-minute swimming test.

Efecto del HIIT en el estado anímico en personas con sobrepeso en un entrenamiento virtual y presencial. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20(1), 1-17. El principal objetivo fue comparar los efectos de una sesión HIIT de 35 minutos, en modalidad virtual y presencial, en los estados anímicos y en el esfuerzo percibido en personas con sobrepeso. Se reclutaron un total de 13 personas (5 hombres y 8 mujeres) con una edad promedio de 37.85 ± 13.20 años (rango entre 17 y 60 años) los cuales fueron asignados a cada una de las tres condiciones de manera aleatoria (control, entrenamiento presencial y entrenamiento virtual). Previo a, e inmediatamente después de cada una de las intervenciones, se aplicó el test POMS para medir los estados anímicos. En lo que respecta al esfuerzo percibido (EP), su medición se llevó a cabo finalizado cada uno de los ejercicios HIIT (no se evaluó durante el calentamiento y el retorno a la calma). Al aplicar un ANOVA de 2 vías de medidas repetidas (condición (3) x medición (2)), se encontró que tanto la tensión como el vigor después de haber aplicado el tratamiento presencial presentaron un aumento significativo; además, la tensión aumentó en la sesión virtual. Por su parte, los valores de EP reportados en las mediciones de las sesiones presencial y virtuales estuvieron por encima de lo sugerido en la literatura. En conclusión, una sesión de HIIT para personas con sobrepeso de manera presencial o virtual presenta resultados similares en los estados de ánimo, excepto el vigor, el cual incrementa solo en la condición presencial; las otras variables mostraron un comportamiento similar.

PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20(1), 1-17. The main objective was to compare the effects of 35-minute HIIT session, in both virtual and face-to- face modes, on the mood and the perceived effort of overweight people. A total 13 people (5 men and 8 women) were recruited, in an average age of 37.85 ± 13.20 years (17-60 year range), who were randomly assigned to each of the three conditions (control, face-to-face training, virtual training). Prior to and immediately after each of the interventions, the POMS test was applied in order to measure mood. The measuring of perceived effort (PE) was carried out at the end of each of the HIIT exercises (it was not assessed during warm-up or return to calm). When a 2-way repeated-measure ANOVA was applied (condition (3) x measurement (2)), it was found that both stress and vigor after applying face-to-face treatment showed a significant increase. In addition, stress increased in the virtual session. For their part, the PE values reported in the measurements of the face-to-face and virtual sessions were above those suggested in the literature. In conclusion, a HIIT session for overweight people, whether face-to-face or virtual, shows similar results in their moods, except for vigor, which only increases in the face-to-face situation. The other variables showed a similar behavior.

Antes e imediatamente depois de cada uma das intervenções, foi aplicado o teste POMS para medir os estados anímicos. Com relação ao esforço percebido (EP), a medição foi feita ao finalizar cada um dos exercícios HIIT (não foi avaliado durante o aquecimento e a volta à calma). Ao aplicar um ANOVA de 2 vias de medidas repetidas (condição (3) x medição (2)), observou-se que tanto a tensão quanto o vigor depois da aplicação do tratamento presencial aumentaram de maneira significativa; além disso, a tensão aumentou na sessão virtual. Por outro lado, os valores de EP relatados nas medições das sessões presenciais e virtuais estiveram acima do sugerido na literatura. Como conclusão, uma sessão de HIIT para pessoas com sobrepeso, seja presencial ou virtual, apresenta resultados semelhantes nos estados de ânimo, exceto o vigor, que aumento somente na condição presencial; as outras variáveis mostraram um comportamento semelhante.

Efecto de la práctica mental kinestésica en la fuerza y actividad mioeléctrica del bíceps braquial, luego de un periodo de inmovilización de codo en adultos-jóvenes sanos / Effects of kinesthetic mental practice in strength and myoelectric activity of the brachialis biceps due to an elbow immobilization period in healthy young adults

RESUMEN: El objetivo de este estudio fue determinar el efecto de la práctica mental kinestésica (PMK) en la fuerza y actividad eléctrica muscular (AEM) del bíceps braquial, luego de un periodo de inmovilización del codo en un grupo de personas adultos jóvenes sanos. Un total de 14 personas (18,64 ± 0,92 años de edad) participaron voluntariamente del estudio, a las cuales se les evaluó la fuerza muscular de prensión y la AEM del bíceps braquial utilizando un dinamómetro de mano y un equipo de electromiografía, respectivamente, antes y después de un periodo de inmovilización del brazo no dominante, y se asignaron aleatoriamente a uno de dos grupos: grupo control (GC) o experimental (GE). El GE realizó PMK: tres series de 15 repeticiones con un minuto de descanso entre series, tres veces al día durante los seis días de inmovilización, mientras que el GC no realizó PKM durante su inmovilización. Al aplicar una prueba de ANOVA de dos vías, no se encontraron diferencias significativas en la fuerza ni en la AEM. Sin embargo, la fuerza del GC disminuyó en 23,75%, mientras que la del GE aumentó en 33,19%. Los resultados sugieren que un periodo de inmovilización del codo de seis días no fue suficiente para que la fuerza ni la AEM disminuyan significativamente, lo que supone que la PMK realizada no es necesaria en periodos menores a seis días.

ABSTRACT: The aim of this study was to determine the effect of kinesthetic mental practice (KMP) on the strength and muscular electrical activity (MEA) of the brachial biceps, after a period of immobilization of the elbow in a group of healthy young adults. A total of 14 volunteer participants (18.64 ± 0.92 years of age) were part in the study. The muscle strength and the AEM of the brachial biceps were assessed using a hand dynamometer and an electromyography equipment, respectively, before and after a period of immobilization of the non-dominant arm. After the pretest, they were randomly assigned to one of two groups: control group (GC) or experimental group (GE). The GE performed 3 sets of 15 repetitions with one-minute rest between sets, three times a day of PMK during the 6 days of immobilization, while the GC did not perform PKM during its immobilization. A 2-way ANOVA test (group x measurement) indicated non-significant differences in strength or AEM. However, the strength of the GC decreased by 23.75%, while increased by 33.19% in the GE. The results suggest that a period of immobilization of the elbow of 6 days was not enough for the strength or the AEM to decrease significantly, which means that the PMK is not necessary in periods of immobilization of less than 6 days.

Al aplicar un análisis de varianza (ANOVA) de dos vías mixto [grupo (3) x medición (3)] se encontró que el desempeño de los tres grupos mejoró significativamente en la prueba de adquisición y retención. El ANOVA de dos vías mixto [grupo (3) x medición (2)] indicó que no hubo diferencias significativas en la AEM. La PF, PM y PC favorecieron el aprendizaje de la destreza; sin embargo, no se encontraron cambios en la actividad eléctrica del músculo braquiorradial del antebrazo dominante.

Abstract The purpose of this study was to analyze the effectiveness of mental practice (MP), physical practice (PP), and their combination (CP) in the performance of the dribbling skill in field hockey, and the brachioradialis muscle electrical activity (MEA) of the dominant forearm. A total of 27 freshmen enrolled in the Human Movement Science program with no experience in the skill was randomly assigned to one of the three groups (MP, PP, and CP). Skill performance was assessed by total time using Smartspeed Pro photocells, while MEA was tested with an electromyogram using Noraxon M400. Research was conducted in two sessions. In the first session, the pretest, experimental practice by group, post test, and MEA were conducted. In the second session, held a week later, a retention test was conducted. After a two-way mixed ANOVA [group (3) x measurement (3)], the acquisition and retention test performance improved significantly in the three groups. The two-way mixed ANOVA [group (3) x measurement (2)] showed no significant differences in MEA. PP, MP, and CP enhanced skill learning; however, no significant changes were found in the brachioradialis muscle electrical activity of the dominant forearm.

Resumo O presente estudo teve como objetivo analisar a efetividade da prática mental (PM), prática física (PF) e sua combinação (PC) no desempenho da destreza de dribbling de hóquei de salão e a atividade elétrica do músculo (AEM) braquiorradial do antebraço dominante. Um total de 27 estudantes universitários do primeiro ano do curso de Ciências do Movimento Humano, sem experiência prévia na destreza, foram atribuídos aleatoriamente a um de três grupos (PF, PM e PC). O desempenho da destreza foi avaliado por meio do tempo total, utilizando fotocélulas SmartspeedPro e a AEM foi medida com um eletromiógrafo Noraxon M400. A pesquisa foi realizada em duas sessões. Na primeira sessão, foram feitos o pré-teste, a prática experimental de acordo com o grupo correspondente e o pós-teste do desempenho e da AEM. Na segunda sessão, uma semana despois, foi avaliado o desempenho em um teste de retenção. Ao ser aplicada uma análise de variância (ANOVA) mista de duas vias [grupo (3) x medição (3)], observou-se que o desempenho dos três grupos melhorou significativamente no teste de aquisição e retenção. A ANOVA mista de duas vias [grupo (3) x medição (2)] mostrou que não houve diferencias significativas na AEM. A PF, PM e PC favoreceram a aprendizagem da destreza; não obstante, não foram encontradas alterações na atividade elétrica do músculo braquiorradial do antebraço dominante.
