eSports gaming requires quick and accurate reactions in response to complex visual stimuli for optimal performance. The purpose of this study was to examine the relationship between components of physical fitness and reaction time (RT) in eSports gamers. 27 eSports gamers participated. Visit 1 included physical fitness assessments. Visit 2 included a familiarization with the Stroop Task. During Visit 3, subjects completed the Stroop Task again; data from this visit was used for analyses. For congruent, incongruent and control trials, an inverse efficiency score (IES) was calculated. Pearson correlations were used to determine the relationship between components of physical fitness and mean RT. There was a significant correlation between mean RT and cardiorespiratory fitness (r=-.338, p=.043). IES was significantly related to cardiorespiratory fitness in incongruent (r=-.373, p=.028) and control (r=-.333, p=.045) trials. Results suggest that increased cardiorespiratory fitness can improve reaction time and also induce greater efficiency.

Abstract The relationship between parental support and physical activity enjoyment appears to be mediated by individual-level factors. The aim of this study was to examine whether the relationship between perceived parental support and physical activity enjoyment is mediated by overweight and obese adolescents’ physical fitness, both subjectively and objectively assessed. A total of 163 participants (mean age =14.30 years, 55.8% boys) with an average body mass index of 28.97 kg/m2 took part in this study. Participants completed a questionnaire of parental influence regarding physical activity, a questionnaire of physical self-perception and several fitness tests (cardiorespiratory fitness, lower limbs muscular strength and flexibility) using the ALPHA-fitness battery. The results showed that relationship between perceived parental support and physical activity enjoyment is mediated by the overweight and obese adolescents’ perceived cardiorespiratory fitness and flexibility. We suggest to create educational guidelines for parents to increase the support and improve overweight and obese students’ positive perceived physical competence, in order to achieve a greater adherence to physical activity and greater physical activity enjoyment.

The Relationship

Abstract Background: Studies indicate that cardiorespiratory fitness, muscular strength and body composition are associated with mental health. However, research is scarce concerning this relationship in young adolescents in general and non-existent in Norwegian populations specifically. The aim of the study was to examine the relationship between different health-related aspects of physical fitness and self-reported mental health in Norwegian adolescents. Methods: Participants from four regions of Norway (n = 1486; mean age = 13.9; girls = 50.6%) completed the Strengths and Difficulties Questionnaire, and were measured for cardiorespiratory fitness, muscular strength and body composition. Linear mixed effects models were conducted to assess the associations between the health-related aspects of physical fitness and the total difficulties score of the questionnaire. Results: Body composition was not associated with total difficulties score. Muscular strength independently was associated with total difficulties score, but when all independent variables were entered in the fully adjusted model, only cardiorespiratory fitness was associated with total difficulties score. School clusters were included as random effects and all models were controlled for sex, socioeconomic status and birthplace (domestic or foreign). Conclusions: A small but significant negative association between cardiorespiratory fitness and total difficulties score indicated that higher cardiorespiratory fitness predicted better mental health in Norwegian adolescents. The results suggest that muscular strength is not associated with mental health in adolescents, when controlling for cardiorespiratory fitness. Future research on how exercise affects mental health should investigate whether there is a greater effect for participants who improve their cardiorespiratory fitness.

Depression is the most common mental disorder, affecting around 5% of adolescents. Physical fitness is considered a powerful marker of physical and mental health. The scientific results on the relationship between physical fitness and depression in the adolescent population are mixed. Therefore, the aim of the current study was to analyse the association between objectively assessed physical fitness and self-rated risk of depression in a group of adolescents. A total of 225 participants (44% girls), aged 13.9 ± 0.3 years, from the Deporte, ADOlescencia y Salud (DADOS) study were included in the analyses. Field-based Assessing Levels of Physical fitness and Health in Adolescents (ALPHA) health-related fitness test battery was used to objectively assess physical fitness components. The Behavior Assessment System for Children (BASC) level 3 was used to evaluate self-rated risk of depression. Our results showed that self-rated risk of depression was inversely associated with cardiorespiratory fitness (β = −0.172), as well as positively associated with body mass index (β = 0.146) and waist circumference (β = 0.137) (all p < 0.05). Adolescents with low levels of cardiorespiratory fitness had significantly higher odds of self-rated risk of depression (OR = 7.17; 95% CI, 1.51–33.95). These findings suggest that health-related physical fitness, particularly cardiorespiratory fitness and body composition, is associated with depression in adolescents.

The Relationship

Thirty-four women ages 60 to 75 years were divided into two groups based on self-reported physical activity levels. The presence of significant fitness differences between the two activity groups was confirmed by testing all subjects on a well-established submaximal mile walking test. Both groups performed a reaction time task under two levels of task complexity: simple reaction time (SRT) and complex choice reaction time (CCRT). Time to react in milliseconds was recorded for both levels of task complexity. Analysis of variance revealed that the active group reacted faster (p< .05) than the less active group on CCRT (activeM,1.100 sec; less activeM, 1.818 sec). However, SRT times did not differ between groups (activeM, .345 msec; less activeM, .374 msec). This finding lends support to the hypothesis that cognitive task complexity influences the strength of the association between physical fitness and cognitive performance in older adults.

Pencak silat is a sport that requires agility, speed, balance and body slenderness. Vitamin C and iron are part of the micronutrients that can support the athlete’s physical fitness. The aims of this study was to determine the relationship between the adequacy of vitamin C and iron with physical fitness of pencak silat athletes IPSI Lamongan. This study used observational analytics with case-control design with 20 samples of athletes, divided into 10 cases and 10 controls. The result of analysis from 2×24 hour food recall method in each case group was 9 (90%) athletes did not meet the requirement of vitamin C (<77%) and 8 (80%) athletes did not meet the requirement of iron and control group there were 7 (70 %) Athletes are not sufficient for vitamin C (<77%) and 6 (60%) of athletes are inadequate for iron (<77%). From the statistical test using chi-square, it was found that there was no significant relationship between vitamin C and iron adequacy with physical fitness (TKJI) with p=0.580 and p=0.620. Conclusion: adequacy level of vitamin C and iron of pencak silat athletes IPSI Lamongan is not meet their requirement yet.

Magicians can often hide their method for a trick in plain sight by effecting a phenomenon known as change blindness. The purpose of this study was to find the reason for why an individual is induced with change blindness. Alpha oscillations are known to impair detection of visual stimuli, but it is unclear if this is due to increased guess rate or decreased fidelity of the mental representation. Here we estimated fidelity and guess rate as a function of pre-stimulus alpha oscillations using a change blindness task. In this study, each trial began with an array of 6 Gabor patches with a fixated dot that subjects were instructed to keep their eyes on. As the array traveled to the center of the screen, it either changed direction vertically at 90 degrees or continued horizontally. When the array switched direction, one of the Gabor patches rotated 30 degrees simultaneously. Subjects were then asked to identify which patch rotated. EEG (electroencephalography) data was simultaneously recorded with eye-tracking as subjects performed the task. Twenty-eight participants performed this task, which included six blocks of forty-eight trials. There were two different types of trials: flexion, in which the array changed direction, and control, in which the array did not change direction. Reaction time tended to be slower in flexion trials, and we found that the change in direction affected the subject’s ability to see the Gabor patch rotation. Based on the event-related potential results, which are an average of EEG signals aligned to the start of a trial, we could see that the P300 differed between correct flexion, incorrect flexion, and control trials. The P300 can be interpreted as a marker of consciousness. This difference demonstrates that the subject’s attention is automatically drawn to a larger change in stimuli.

Abstract Background There is the need to encourage physical activity (PA) among adolescents with overweight or obesity. Objectives The present study aimed to assess the relationship between health-related physical fitness (PF) and nutritional status, and to identify those activities more suited to adolescents with excess weight. Methods This cross-sectional study included 3,062 in-school adolescents, aged 10–18 years. We collected information on sex, age, weight, height, skinfold thickness, trunk height and leg length, and calculated body mass index (BMI) z-score, fat mass percentage, and peak height velocity (PHV). Participants were tested for PF by the 20-m shuttle run test (cardiorespiratory fitness); medicine ball throw and standing long jump tests (musculoskeletal fitness) and sit and reach test (flexibility). We used generalized linear mixed models (GLMM) to analyze the relationship between nutritional status and performance in the fitness tests, controlled for maturity offset and fat mass percentage. Results 1,563 (51%) were boys, mean age 12.6 years (±1.8), 22.8% were overweight and 12.5% had obesity. In both sexes, adolescents with obesity did better in the upper body strength test than their eutrophic peers. Boys with obesity had worse cardiorespiratory fitness and lower body muscular strength than eutrophic boys. Girls with obesity had similar cardiorespiratory fitness and better lower body strength than eutrophic girls. Conclusion In muscular strength fitness tests, adolescents with obesity performed similarly to, or better than, their eutrophic peers. Motivation to maintain regular PA is reinforced by positive experiences. Interventions that emphasize muscular strength PF should be developed for adolescents with obesity.

Promotion of healthy active behaviors should start from early ages, as behaviors learned in youth are more likely to endure. A fundamental body of research in this field focuses on the implementation of programs within physical education (PE), thanks to its favorable characteristics. However, traditional PE based on exercise training and controlling styles seems to have weaker association with students’ health benefits. For this reason, the aim of this study was to assess the effects of a game-based PE program on physical fitness and psychological health in schoolchildren aged 10 to 12 years old. A total of 252 students were distributed in experimental (EG, games-centered activities) and control (CG, traditional exercise training activities) groups. The program lasted 6 months. Health-related physical fitness components, psychological wellbeing, self-esteem, stress, and anxiety were assessed before and after the treatment. Both groups increased physical fitness at post-test; however, cardiorespiratory fitness did not improve. No differences were found between the groups at post-test. Our results show that games may be as effective as traditional training methods; yet, they suggest that PE alone may be insufficient for obtaining substantive benefits in cardiorespiratory fitness, regardless of the type of task presented.

The aims of the present study were (1) to determine the differences in body composition and the physical and physiological profile of handball youths across age categories, and (2) to analyze the mediation effect of different categories on the relationship between lean mass or fat mass and specific physical handball capacities. Fifty-four young handball players aged 13 to 18 were assigned to U14 (13- and 14-year-olds), U16 (15- and 16-year-olds), and U18 (17- and 18-year-olds). Body composition was measured using multi-frequency bioelectrical impedance (Inbody®, 230). Handball physical fitness was assessed using handgrip force, jumping tests (squat jump, countermovement jump, countermovement jump with aimed arms), a 30-m sprint, a change-of-direction test (T-half agility test and modified Illinois test), and a Yo-Yo intermittent recovery test level 1. Simple mediation analysis was performed to analyze whether the category mediated the relationship between lean mass or fat mass and physical capacities. No significant differences were observed according to category for the majority of the measured parameters, except for height, lean body mass, and arm span. Lean body mass increased significantly as player category increased (p < 0.05; ∆ = 4.66–9.38; effect size (ES) = 0.96–1.92). The increase in handball category enhanced the majority of the physical capacities evaluated; however, these differences were reduced between the U16 vs. U18 categories. The indirect mediation effect suggests that handball category mediated the relationship between lean mass and upper and lower strength, velocity, agility, and cardiorespiratory fitness. In contrast, an indirect effect suggests that category mediated the relationship between fat mass only in agility and cardiorespiratory fitness. We conclude that U18s showed better body composition parameters, as well as better physical performance scores. Handball category clearly mediated the relationship between body composition through lean mass and fat mass and the physiological profile in handball youth, but lean mass proved to be more relevant when mediating physical performance.
