The influence of physical fitness on self-confidence and its impact on physical education academic achievement. A study on grade V school students

Background and Study Aim. Much of the crisis in the current education system is caused by students’ low physical fitness and self-confidence. This study aims to determine the effect of physical fitness on self-confidence and its impact on the academic achievement of Physical Education of Grade V Primary School students. Materials and Methods. This research is correlational. The subjects were Class V students in elementary schools, with a sample size of 115 students (66 males, 49 females, ages 10-12) selected through random sampling. Academic achievement was measured through Physical Education report card scores, physical fitness through the Indonesian Student Fitness Test (TKSI), and physical self-confidence through a self-confidence scale. Data analysis was performed using regression techniques via SPSS 21. Results. Physical fitness positively affected self-confidence (r = 0.259, p = 0.005 < 0.05) and Physical Education academic achievement (r = 0.513, p = 0.000 < 0.05). Self-confidence also significantly impacted Physical Education academic achievement (r = 0.519, p = 0.000 < 0.05). Conclusion. Better physical fitness enhances students’ self-confidence and positively influences their academic performance in Physical Education.

Influence of physical fitness on decision-making of soccer referees throughout the match

The purpose of this study was to analyze the relationships between physical fitness and physical performance in competition and the decision-making (successes and errors). A sample of 22 male national-level soccer referees (weight: 72.7 kg; height: 178.0 cm; age: 23.4 years) participated in this study. Physical fitness was assessed through 6 series of 40 m (velocity) and Yo-yo (aerobic) test in annual exam by Soccer Committee, physical performance was performed through the total distance covered in competition (Experiment 1), and decision-making was registered through a simulated Video Assistant Referee system (VAR) with the consensus of 2 national referees evaluating only warnings (yellow cards), expulsions (red cards), established penalties and obvious goal actions (called and no called) (Experiments 2 and 3). Results showed that physical fitness test was related with total distance (rho = 0.63, p < .01) and success rate percentage (rho = 0.74, p < .05) registered during competition. The success rate percentage, in the first half, was observed 44% successes, and in the second half, 59% successes. The number of events called was related with the physical fitness test score (R2 = 0.71, p = .035; R2 = 0.64, p = .056, respectively). As conclusion, the main finding of this study has provided insight into decision-making behavior in real competitive matches and the physical fitness was the predictor of the successful decision-making being able to determine the permanency, promotion or decrease of category.

Influence of physical fitness and retinal microcirculation on the development of cognitive abilities from childhood to preadolescence

The retinal microcirculation serves a proxy of cerebrovascular function and has been linked with both physical fitness and cognitive function. We investigated the role of physical fitness for the development of executive function in children as well as its mediation by microvascular health. Using a cross-lagged panel design, 365 children aged six to eight years completed a baseline assessment, which was followed up after four years. Retinal vessel analysis was performed on digital retinal images obtained with a fundus camera. Additionally, a computerized Flanker task was administered to assess the inhibitory aspect of executive function. With regard to physical fitness tests, participants completed a shuttle run and 20-m sprints. Path-analyses showed that higher performance on the shuttle run and 20-m sprint at baseline were both associated with lower reaction times on the Flanker task at follow-up, when autoregressive effects were accounted for. Stages achieved on the shuttle run at baseline were further related to narrowing of retinal venular diameters, which in turn predicted performance on the Flanker task. However, the direct relation of physical fitness components to reaction time was higher compared to the indirect relation via retinal venular diameters. High physical fitness contributes to the development of cognitive abilities from childhood to preadolescence. This association is not mediated by retinal vessel diameters, while the microvascular phenotype of narrower retinal venules is independently related to a better development of information processing and inhibitory control.

Influence of physical fitness and weight status on autonomic cardiac modulation in children.

This study provides reference values for cardiovascular modulation at rest, during maximal exercise test and recovery after exercise in Caucasian children according to weight status and cardiorespiratory fitness (CRF)level. Additionally, the current study analyzed several correlations between autonomic cardiovascular modulation, cardiorespiratory performance and cardiometabolic risk. The principal goal of this study was to analyze cardiac function at rest, during maximum exercise, and during the recovery phase in children grouped according to weight status and CRFlevel. One hundred and fifty-two healthy children (78 girls) 10-16 years of age were divided into three groups: soccer and basketball players (SBG), endurance group (EG), and sedentary people with overweight and obesity (OOG). A cardiac RR interval monitor recorded the cardiac data and specific software analyzed the cardiac autonomic response through heart rate (HR) and HR variability. The study analyzed resting HR (RHR), HRpeak, and HR recovery (HRR). OOG showed significant poorer performance in the Léger test lower V̇O2 max and higher values of blood pressure at rest and post-exercise than sport groups. The EG presented the best results in CRF and cardiometabolic risk (CMR) in relation to SBG and OOG. The OOG showed higher percentage of HR values, compatible with an unhealthy cardiovascular autonomic modulation than the sport groups, with significant differences in bradycardia, HR reserve, and HRR 5 min. Aerobic performance, vagal activity, blood pressure, chronotropic competence, and HRR have significant associations with CMR parameters. The current study presents reference values of autonomic cardiac function in Caucasian children according to weight status and cardiorespiratory fitness level. Aerobic performance, vagal activity, blood pressure, chronotropic competence, and heart rate during the recovery period after exercise have significant associations with cardiometabolic risk parameters. Children with overweight and obesity show signs of autonomic dysfunction reflected as low cardiac vagal activity and poor chronotropic competence.

Influence of Parental Perception of Child's Physical Fitness on Body Image Satisfaction in Spanish Preschool Children.

To find out how self-perceived physical fitness influences self-perceived body image in preschoolers. 475 preschool pupils were recruited in the schools of Extremadura (Spain). They were administered a sociodemographic questionnaire, the Preschool Physical Fitness Index (IFIS) and the Preschool Body Scale (PBS). Significant correlations (p < 0.05) were observed between body dissatisfaction and perceived physical fitness (IFIS), being higher in girls. In terms of variables, general fitness (<0.001), cardio-respiratory fitness (<0.001), muscular strength (<0.001), speed/agility (<0.001) and balance (<0.001) have a negative, medium and significant association with body dissatisfaction in girls; however, this association was lower in the case of boys. The influence of physical fitness had a clear impact on self-perceived body image. With better findings on self-perceived physical fitness variables (IFIS) there was less body dissatisfaction (PBS), especially in the female sex. The results also showed that parents who perceived their children to be in poorer physical condition had higher body dissatisfaction. Therefore, it would be interesting for the context involved, particularly parents, to implement strategies to improve positive body image through the promotion of physical education and physical fitness at an early age.

The impact of physical fitness, social life, and cognitive functions on work ability in middle-aged and older adults

ObjectiveDemographic changes encompass societies to maintain the work ability (WA) of aging workforces. The present study explored the relationship between modifiable lifestyle factors, cognitive functions, and their influence on WA, using a multi-group structural equation approach.MethodCross-sectional data from 247 middle-aged and 236 older employees from the Dortmund Vital Study were included in this analysis. We proposed a model with three exogenous variables (Physical Fitness, Cognitive Functions, and Social Life), and with WA as the endogenous variable. WA was measured with the Work Ability Index (WAI), which considers job demands and individual physical and mental resources. Multi-group analyses were based on the principles of invariance testing and conducted using robust estimation methods.ResultsResults revealed that Social Life outside work had significant positive effects on WA in both, middle-aged and older adults. Physical Fitness had a significant effect on WA only in middle-aged adult, and Cognitive Functions had no significant influence on WA in either group. In older adults, Physical Fitness correlated with Cognitive Functions, whereas in middle-aged adults, Cognitive Functions marginally correlated with Social Life.ConclusionsOur results underline the importance of an active social life outside the workplace for WA, regardless of the employees’ age. The influence of Physical Fitness on WA changes with increasing age, indicating the necessity to have a differentiated view of age effects and interacting influencing factors. Our research contributes to the knowledge of how WA could be most effectively promoted in different age groups.Clinicaltrials.gov NCT05155397; https://clinicaltrials.gov/ct2/show/NCT05155397.

Influence of Physical Fitness, Anthropometric Profile, and Biological Maturation on Technical Performance and Enjoyment of Untrained Children Who Participate in Continuous and Fractional Small-Sided Games.

A crossover-design study in which 12 children participated in two regimens of SSG (continuous and fractional). At the beginning of the study, all children were evaluated using physical fitness tests (horizontal jump test, vertical jump, cardiorespiratory fitness, and agility), anthropometric profile (weight, height, Body Mass Index (BMI), and waist circumference (WC)), and biological maturation (peak years of growth velocity). All sessions were recorded and analyzed with the Performance Assessment in Team Sports instrument, and at the end of each game each child was asked to answer a scale of enjoyment for physical activity. The results of the paired samples t-test showed no significant differences in the measures of technical performance and perceived enjoyment for the continuous and fractional regimens of SSGs (p &gt; 0.05). The correlation results showed that technical performance in the continuous and fractional regimes was related to agility, horizontal jump, and height, while biological maturation was only related to technical performance in the fractional regimen of SSGs. Perceived enjoyment showed a negative relationship with weight, height, BMI, and WC. The fractional and continuous regimens of SSGs implemented in this study induced similar technical demands and enjoyment. Furthermore, the results suggest that physical fitness, anthropometric profile, and biological maturation may influence the technical performance and enjoyment of SSGs.

The Effect of Physical Fitness and Self-Confidence on the Martial Arts of Pencak Silat

This study aimed to determine the effect of physical fitness and self-confidence on the martial art of Pencak Silat. The research method used is the ex post facto method. The research design describes the relationship or influence between a variable and other variables. The population is students who take extracurricular Pencak silat at SMPN 1 Parongpong, with a sample of 30 people. The test instrument for martial arts skills is the Pencak silat regarding single empty-handed moves; physical fitness tests are TKJI for the age range of 13-15 years and a self-confidence questionnaire. Based on the processing and analysis, they use the technical correlation analysis but were previously tested for normality, regression and linearity. The hypotheses of this study are 1) With a positive effect, the higher the physical fitness, the better the martial arts skills of Pencak silat. There is an influence of physical fitness on the martial art of Pencak silat by 55.91%, 2) With a positive impact, the higher the self-confidence, the better the martial arts skills of Pencak silat. There is an influence of self-confidence on the martial art of Pencak silat by 27.29%, and 3) Of the two variables, the effect is excellent on these skills. So there is an influence between physical fitness and self-confidence on the martial art of Pencak silat by 235.26%.

РАЗВИТИЕ ОБЩЕЙ ВЫНОСЛИВОСТИ В ЦЕЛЯХ СОВЕРШЕНСТВОВАНИЯ НАВЫКОВ СТРЕЛЬБЫ ИЗ ПИСТОЛЕТА

Currently, the issues of physical training of the population are actively discussed even at the highest level. The fact is that physical training has a positive effect on the psycho-emotional state of individuals, especially if the activity of such individuals is constantly associated with stress, negative external influences. The latter include employees and cadets of law enforcement agencies, who in the course of their daily activities face not only physical activity, but also stress. An important direction in the training of cadets and law enforcement officers is fire training, including pistol shooting, the improvement of skills in which will be discussed in this article. So, when performing statistical exercises with firearms, when aiming, there is tension in the chest, and as a result, a decrease in lung volume, the priority of shallow breathing. In addition, when aiming with a pistol, the posture worsens the posture, developing a stoop. From the foregoing, it follows that for effective firepower training, cadets and law enforcement officers must be prepared for high physical exertion. In other words, they must train their endurance. In order to develop general endurance, special techniques have been developed that will be discussed in this article. So, in this article, the author analyzes the development of general endurance in order to improve pistol shooting skills. Emphasis is placed on the influence of physical fitness and endurance on pistol shooting skills.

Influence of Physical Fitness and Attention Level on Academic Achievements of Female and Male Military Academy Cadets in Poland.

A professional soldier should be characterized not only by high physical fitness but also by high intellectual and cognitive skills. Therefore, it is important to focus on the future commanding cadre-cadets that are educated in military academies. The aim of the study was to look for correlations between the level of physical fitness and attention and academic achievements (AA) in different subjects among cadets studying at military academies. The research group consisted of students of a military academy in Poland, i.e., 228 cadets, including 31 women and 197 men. Correlations between explained and explanatory variables were assessed using Pearson’s correlation. Correlations between AA and somatic parameters and motor components were analysed using optimal regression, using the best subset method. A statistical difference was found between men and women in terms of the level of somatic and motor development; men also performed significantly better in practical military subjects. In the female group, dominant hand strength is a significant determinant of AA in civilian and theoretical military subjects. The findings suggest the need for specialized training aimed at bridging the major differences in physical fitness between men and women by placing greater emphasis on muscle strength development.

Heart rate variability and stress perception: The influence of physical fitness

The autonomic nervous system (ANS) is somewhat linked to perceived stress. This relationship may be modulated by the individual's training status. The aim was to assess whether heart rate variability (HRV) and perceived stress were interrelated in healthy subjects with various levels of training status. One hundred and seventeen healthy participants (mean age 20 ± 3 yrs) were divided into 3 groups according to their training status: power-trained athletes ( n = 43), endurance-trained athletes ( n = 36), and untrained volunteers ( n = 38). The perception of stress was measured using the perceived stress scale questionnaire, heart rate (HR) was recorded at rest, and HRV analyses were made in time and frequency domain using the Kubios application. Endurance-trained athletes showed higher levels of HRV compared to untrained and, to a lesser extent, to power athletes. HRV parameters of untrained subjects perceiving less stress did not differ from those of endurance-trained athletes who also perceived less stress. Power-trained athletes who perceived less stress had higher values of SD1, RMSSD, HF, and log HF ( P < 0.05, P < 0.05, P < 0.01; P < 0.05 respectively) compared to those who perceived more stress. Our data indicate that training status modulates HRV, and that changes in perceived stress are associated with changes in HRV. Power-trained athletes who perceived less stress had greater HRV compared to athletes who perceived more stress. These results may be important in terms of understanding ANS modulation and stress perception for better managements of stress and/or training/recovery processes in athletes with various training status. Le système nerveux autonome (SNA) est quelque peu lié à la perception du stress. Cette relation peut être modulée par le statut d’entraînement du sujet. L’objectif était d’évaluer si la variabilité de la fréquence cardiaque (VFC) et le stress perçu étaient interdépendants chez des sujets sains mais ayant différents niveaux d’aptitude physique. Cent dix-sept participants (âge moyen 20 ± 3 ans) ont été subdivisés en 3 groupes en fonction de leur statut d’entraînement : athlètes entraînés en puissance ( n = 43), athlètes entraînés en endurance ( n = 36) et des sujets non entraînés ( n = 38). Le stress perçu a été mesuré à l’aide d’une échelle de perception du stress. La fréquence cardiaque (FC) a été enregistrée au repos et les analyses de la VFC ont été effectuées à l’aide de l’application Kubios. Les athlètes entraînés en endurance ont montré des niveaux plus élevés de VFC par rapport aux sujets non entraînés et, dans une moindre mesure, aux athlètes de puissance. Les paramètres de la VFC des sujets non entraînés percevant moins de stress ne différaient pas de ceux des athlètes endurants qui percevaient également moins de stress. Les athlètes entraînés en puissance qui percevaient moins de stress avaient des valeurs plus élevées de SD1, RMSSD, HF et log HF ( p < 0,05, p < 0,05, p < 0,01; p < 0,05 respectivement) par rapport à ceux qui percevaient plus de stress. Nos données indiquent que le statut d’entraînement module la VFC et que les changements du stress perçu sont associés à des changements de la VFC. Les athlètes entraînés en puissance, qui percevaient moins de stress, avaient une plus grande VFC par rapport aux athlètes qui ressentaient plus de stress. Ces résultats peuvent être importants en termes de compréhension de la modulation du SNA et de la perception du stress pour une meilleure gestion du stress et/ou des processus d’entraînement/récupération chez des sujets ayant différents statuts d’entraînement.

Does firefighters’ physical fitness influence their cardiac parasympathetic reactivation? Analysis with post-exercise heart rate variability and ultra-short-term measures

Purpose. This study assessed the influence of firefighters' physical fitness on performances and parasympathetic reactivation in rescue interventions, and tested the validity of post-exercise ultra-short-term heart rate variability. Methods. Twenty-four firefighters were assigned to two groups based on their fitness and performed three simulated interventions. The mean completion time was recorded. The post-exercise root mean square of successive differences of R–R intervals (LnRMSSD) was determined from both criterion (between 5 and 10 min) and ultra-short-term (every 1-min segment from minutes 0–6) analyses. Results. Completion time was better for the highest fitness group in the three simulated interventions while post-exercise LnRMSSD was not influenced by the firefighters' fitness. Reliability between ultra-short-term and criterion analyses differed between the segments tested; minute 5–6 revealed the highest intra-class correlations (0.86–0.97). Concerning sensitivity of both analyses, the criterion analysis revealed differences between the three rescue interventions and the fitness test, but these results were not observed with ultra-short-term measures. Conclusions. Fitness was associated with firefighters’ performances but not with parasympathetic reactivation in the firefighting intervention. The ultra-short-term measures do not seem to be a suitable post-exercise LnRMSSD analysis because of the low sensitivity to reveal differences among exercise conditions.

Physical fitness modulates mucosal immunity and acceleration capacity during a short-term training period in elite youth basketball players

This study aimed to investigate the effect of physical fitness level (Yo-Yo intermittent recovery test level 1 [Yo-Yo IR 1]) and initial stress level (salivary cortisol [SC]) on salivary immunoglobulin A secretion rate (SIgA rate ), and the influence of physical fitness on accelerations (external training load; eTL) and training impulse (TRIMP; internal training load; iTL), in 20 elite youth male basketball players (14.5 ± 0.5 years; height, 177 ± 10 cm; body mass, 69 ± 13 kg) following a short-term training stress (two daily consecutive basketball-training sessions). Saliva samples were collected before and after the experimental period. A multiple linear regression analysis was conducted using the Yo-Yo IR 1 and SC as independent variables, and changes in SIgA rate as dependent variable. The Yo-Yo IR 1 was the only statistically significant variable (R = 0.73; P = 0.001). Participants were divided a posteriori into high fitness (HFG) and low fitness (LFG) groups according to the median-split technique, taking the Yo-Yo IR 1 performance into account, to compare the eTL and iTL. HFG performed a higher total eTL (34 ± 13 vs. 17 ± 7 accelerations; t = 3.4; P = 0.003) but no difference between fitness groups was observed for TRIMP ( t = 0.33; P = 0.74). The results suggest that physical fitness level may play a role on mucosal immunity responses from short-term training stress in youth basketball players. Players with greater level of physical fitness are likely to perform a higher training load without inducing higher stress levels. Cette étude vise à investiguer l’effet du niveau de condition physique (Yo-Yo intermittent recovery test level 1 [Yo-Yo IR 1]) et du niveau initial de stress (cortisol salivaire [CS]) dans le taux de sécrétion de l’immunoglobuline A salivaire [SIgA rate ]), et l’influence du niveau de condition physique sur les accélérations (la charge d’entraînement externe ; eTL) et sur l’impulsion d’entraînement (TRIMP ; la charge d’entraînement interne ; iTL), de 20 jeunes joueurs de basket-ball d’élite masculin (14,5 ± 0,5 années ; taille, 177 ± 10 cm; poids, 69 ± 13 kg), après un stress d’entraînement à court terme (deux jours consécutifs de séance d’entraînement de basket-ball). Les recueils salivaires ont été effectués avant et après la période expérimentale. Une analyse de régression linéaire multiple a été conduite avec Yo-Yo RI 1 et CS comme des variables indépendants et les changements dans SIgA rate comme la variable dépendante. La variable Yo-Yo RI 1 a été le seule variable statistiquement significative (R = 0,73 ; p = 0,001). Les participants ont été séparés a posteriori en groups condition physique élevé (CPE) et condition physique faible (CPF) selon la technique median-split , tenant compte de la performance du Yo-Yo RI 1, comparer le eTL et iTL. CPE a réalisé un total plus élevé de la eTL (34 ± 13 vs 17 ± 7 accélérations ; t = 3,4; p = 0,003), mais aucune différence n’a été enregistrée entre les groups pour le iTL (TRIMP; t = 0,33 ; p = 0,74). Les résultats suggèrent que la condition physique pourrait jouer un rôle dans les réponses immunitaires du stress d’entraînement à court terme des jeunes joueurs de basket-ball. Les joueurs ayant un meilleur niveau de condition physique sont aptes de réaliser une charge d’entraînement plus élevée sans induire des niveaux de stress plus élevés.

The Influence of Physical Fitness on Reasons for Academy Separation in Law Enforcement Recruits.

This study analyzed the effects physical fitness may have on reasons for academy separation in law enforcement recruits. A retrospective analysis was conducted on 401 recruits; 330 recruits graduated (GRAD), and 71 recruits separated at various times during academy. Twenty-eight recruits separated for personal reasons (SEPPR); 18 due to physical training failures (i.e., poor fitness) or injury (SEPFI); and 25 due to academic or scenario failures (SEPAS). Fitness testing occurred prior to academy, and included: Push-ups and sit-ups in 60s; a 75-yard pursuit run (75PR); vertical jump; medicine ball throw; and multistage fitness test (MSFT). A one-way ANOVA with Bonferroni post hoc compared between-group fitness test performance. A multiple stepwise regression calculated whether recruit characteristics or fitness could predict separation. The GRAD group was younger than the SEPAS group (p < 0.01), faster in the 75PR than the SEPFI group (p = 0.02), and completed more MSFT shuttles than the SEPPR and SEPFI groups (p = 0.01). Age predicted GRAD and SEPAS group inclusion; MSFT predicted GRAD, SEPPR, and SEPFI group inclusion. Recruits who had superior high-intensity running capacity (75PR) and aerobic fitness (MSFT) should have a better chance of completing academy. However, this could be influenced by training practices adopted during academy.

Influence of Physical Fitness on Special Judo Fitness Test Performance: A Multiple Linear Regression Analysis.

Lopes-Silva, JP, Panissa, VLG, Julio, UF, and Franchini, E. Influence of physical fitness on Special Judo Fitness Test performance: a multiple linear regression analysis. J Strength Cond Res 35(6): 1732-1738, 2021-The purpose of this study was to identify the physical fitness variables that best predict Special Judo Fitness Test (SJFT) performance. Thirty-five male experienced judo athletes took part in this study. All athletes performed 5 tests: upper- and lower-body cycle ergometer graded exercise tests; upper- and lower-body Wingate tests; and SJFT. The peak oxygen consumption (V̇o2peak), maximum heart rate (HRmax), maximum aerobic power, and the variables corresponding to onset blood lactate accumulation (OBLA) were determined during the graded exercise tests. For the Wingate tests, peak power (PP) and mean power were used. Furthermore, the total number of throws, heart rate (HR) immediately and 1 minute after, and SJFT index were calculated. Four separated forward multiple linear regressions (forward model) were used to identify the physical fitness variables that best explained the SJFT variables. Upper-body V̇o2peak (ml·min-1·kg-1) explained 27% of variance in the total number of throws, whereas an additional 7% was explained by upper-body PP. Upper-body HRmax explained 46% of the variance in the HR immediately after the SJFT, whereas lower-body HR at OBLA accounted for an additional 8%. Lower-body HRmax explained 21% of the variance in the HR 1 minute after the SJFT, whereas peak lactate ([La-]peak) after the lower-body graded exercise test accounted for an additional 12%. Upper-body V̇o2peak (ml·min-1·kg-1) alone accounted for 15% of the variance in the SJFT index. Based on these results, the data suggest that physical fitness variables, derived from upper- and lower-body aerobic and anaerobic tests, have a small ability to predict the SJFT variables.
