Lower Physical Fitness Is Associated with Injuries in Iranian National Futsal Teams: A Prospective Study

Background: Several studies have investigated risk factors for injury in different sports. However, little scientific information is available in relation to futsal injuries. Objectives: This study prospectively analyzed the influence of physical fitness parameters on the occurrence of futsal injuries in Iranian national teams. Methods: Prior to the season, all 55 players of 3 Iranian national futsal teams took part in a series of tests for physical fitness parameters such as cardio-respiratory fitness, muscle strength, body composition, flexibility, agility, and speed. Team physicians recorded all injuries, medical attention, and time loss due to the injury throughout the match and training sessions. Results: During 18 months, 54 futsal injuries were sustained by 32 players. Injured players had poorer performance at baseline in agility, speed, and vertical jump than players who did not incur an injury during the season. Lower maximal oxygen uptake (VO2max) values were associated with a higher injury risk. No differences between injured and uninjured players were observed in age, anthropometric data, flexibility, and lower extremity strength. Conclusions: Some physical fitness parameters were associated with the risk of injuries in futsal. Therefore, improving physical fitness might help to reduce the number of futsal injuries.

Ski Racers

Alpine ski racing is a sport with a high risk of injuries. In order to contribute to the longitudinal career development of young athletes, prevention measures should be elaborated. Therefore, the aim of the present study was to investigate prospectively the role of biological maturity status, and changes in anthropometric characteristics and physical fitness parameters over one season in elite youth ski racers younger than 15 years. Eighty-nine elite youth ski racers (39 females, 50 males), aged 10–14 years (mean age: 12.1 ± 1.3), were investigated. Anthropometric characteristics and physical fitness parameters were assessed prior and after the winter season; traumatic and overuse injuries were recorded over the 32 weeks. Binary logistic regression analyses (R² = 0.202–0.188) revealed that the biological maturity (Wald = 4.818; p = 0.028), and changes over the season in the jump agility test (Wald = 4.692; p = 0.03), in body height (Wald = 6.229; p = 0.013), and in leg length (Wald = 4.321; p = 0.038) represented significant injury risk factors. Athletes who could improve their jump agility performance more, had smaller changes in the anthropometric characteristics and who were closer to their peak height velocity were at a lower injury risk. In the context of injury prevention, regular neuromuscular training should be incorporated, and phases of rapid growth have to be considered.

In order to monitor training effects and physical developments in elite sports, it may be beneficial to perform anthropometric measurements and physical fitness tests regularly. In this study, the relationship between the anthropometric properties and physical fitness values of elite figure skating athletes were investigated. 21 elite athletes in the 11-16 age group, female (n=12) and male (n=9), participated in the study. Anthropometric measurements were taken in accordance with The International Society for the Advancement of Kinanthropometry (ISAK) protocol. Σ6 and Σ8 skinfold thickness, body fat ratio (BF%), body mass index (BMI), Manouvrier Index (MI), waist/hip ratio and somatotype components in girls Group II, III and in boys Group II were calculated. Also, balance, flexibility, handgrip strength, vertical jump, agility, medicine ball overhead back throw, speed, and endurance tests were applied to all groups. Descriptive statistical analyzes were made using the IBM SPSS 25.0 statistics program. The relationship between variables was calculated by the Pearson Correlation coefficient. The significance level was taken as p<0.01 and p<0.05. In boys, body weight, body height and arm span, sitting height, BMI, humerus breadth and foot length were observed to be associated with all physical fitness parameters (p<0.01, p<0.05), except balance and agility; Girth measurements were related to handgrip strength, vertical jump, overhead medicine ball backward throw, speed and endurance (p<0.01, p<0.05). Negative relationships of the endomorphic feature with flexibility and endurance were determined (p<0.05). In girls, it was found that body weight, body height, and arm span, sitting height and BMI were related to flexibility, handgrip strength, medicine ball overhead back throw (p<0.01, p<0.05); girth measurements were found to be related to flexibility, handgrip strength, vertical jump, overhead medicine ball back throw (p<0.01, p<0.05); also, significant correlations (p<0.01, p<0.05) were found between the handgrip strength and breadth measurements. Assessment of the relationship between morphological features and motor skills with specific field tests and standardized tests performed at regular intervals in athletes can contribute to the athletes' selection and training planning of the relevant federations and orientating towards their goals.

The purpose of this study was to generate a physical fitness profile of an interagency hotshot crew mid-way through the wildland fire season. Twenty interagency hotshot crew firefighters completed measures of body composition, aerobic fitness, hamstring flexibility, muscular strength, explosive strength and muscular endurance. Firefighters exhibited 12.9 ± 2.3% body fat, scored 9.4 ± 0.4 min on the 1.5-mile (2.41 km) run, 48.8 ± 5.3 cm on the sit-and-reach test, 63.7 ± 8.2 kg and 58.7 ± 7.6 kg for right- and left-hand grip strength, and 55.9 ± 9.9 cm on the vertical jump. Firefighters scored 45 ± 12 for push-ups, 60 ± 6 for sit-ups and 13 ± 4 for pull-ups. All fitness scores were at or above average compared with sex- and age-corrected norms, and interagency hotshot crew-specific recommendations for completion of the 1.5-mile run, push-up, sit-up and pull-up tests. Although these data provide a cross-sectional gauge of mid-season fitness parameters, it is unclear how the occupational stresses of the job alter common measures of fitness in interagency hotshot crews. Future research may help highlight seasonal fluctuations in physical fitness, and the effect of physical fitness training on fitness parameters throughout the fire season.

The purpose of the current study is to analyze the relationships between physical fitness, selective attention, and academic performance in pre-teens. The sample here consists of 135 participants between the ages of 10 and 12 (M = 11.05; SD = 0.61), with 39.26% female (n = 53) and 60.74% male (n = 82) participants. Horizontal and vertical jump distances, speed, and cardio-respiratory fitness were evaluated to assess physical fitness. The d2 Test of Attention was used to evaluate selective attention. In addition, data were obtained regarding participant academic performance by analyzing the academic performance. The results show significant relationships between the measures analyzed, highlighting positive associations between physical fitness, cognitive functioning, and academic performance. Thus, participants who were fitter scored better on tests of attention (Z133 = −4.07; p < 0.00007, Cohen’s d = 0.75, 95% CI (0.39, 1.11)) and concentration (t133 = −3.84; p < 0.0007, Cohen’s d = 0.69, 95% CI (0.33, 1.05)), as well as having higher academic performance (Z133 = −2.84; p < 0.0035, Cohen’s d = 0.39, 95% CI (0.04, 0.75)). Cardiorespiratory fitness was the measure of physical fitness that best explained these relationships. The results suggest that maintaining and improving the physical fitness of children and adolescents may help their brain function develop better.

The current study aimed at analyzing the relationship between body composition, adherence to the Mediterranean diet (MD), and physical fitness (PF) in a young active population. A total of 1198 athletes (boys = 875; girls = 323) enrolled in different municipal sports schools participated in this study. Data on adherence to the MD (KIDMED questionnaire), anthropometric measurements, and PF (20 m shuttle run test, handgrip strength, vertical jump and forced spirometry) were collected. Results show that the pubertal boys had a higher score in the KIDMED test than the prepubertal ones (+0.38, p = 0.28). Moreover, boys with better adherence to the MD had significantly higher results in handgrip strength (+12.20 regarding low MD group and +9.13 regarding medium MD group, p < 0.05), as well as in forced vital capacity (FVC) (+0.66 regarding low MD group and 0.29 regarding medium MD group, p < 0.05). No differences were found in the girls. Finally, the result of the KIDMED test is a variable with a positive and significant relationship with cardiorespiratory fitness, along with the FVC, percentage of fat mass, and performance in the vertical jump (p < 0.05). It is concluded that adherence to the MD could show a relationship with various PF variables in boys and could be a predictor of cardiorespiratory fitness in both cases.

The aim of this study was to examine the impacts of 8-week plyometric exercise on some physical fitness parameters of women handball players aged 12-16 years old. 40 women athletes, 20-subject and 20-control group, participated in the study. While both group participated in the exercises regularly, subject group joined extra plyometric exercises twice a week. Before exercises pretest and posttest were applied.For statistical analysis, Wilcoxon test was used for comparison of intra-group; Mann-Whitney U test was used for comparison of inter-group, and p<0.05 was accepted as significance level. Significance differences were accepted when the values of body weight, body fat percentage, right / left hand grip (grip) strength, leg and back strength, balance, flexibility, vertical jump, standing long jump, reaction time and 30-meter sprint speed was lower than 0.05 P level (p<0.05).Consequently, it was found that a 8-week plyometric exercises had positive impacts on values of percentage of body fat, vertical jump, standing long jump, 30-meter sprint speed.As a result of this study, because specially designed plyometric exercises have positive impacts on some physical fitness parameters and increment in values of athletes’ individual performance is an important factor, it can be suggested that plyometric exercises should be applied on women handball players.ÖzetBu Araştırma, 8 haftalık pliometrik antrenmanın 12-16 yaş kadın hentbolcuların Göster göster Bazı FİZİKSEL Uygunluk parametrelerine etkisinin İncelenmesi Amacı Ile yapilmistir. 20 Deney oynayan Araştırmaya Aktif hentbol, 20 Ile kontrolün grubu olmak Üzere Toplam 40 kadın sporcu Gönüllü Olarak katılmışlardır.

Aim. The paper aims to study the factor structure of physical fitness in basketball players and identify tests for a qualitative and quantitative assessment of their skills. Materials and methods. The study was conducted from September 2017 to May 2018 at Vyatka State University, Kirov. Fifty-three students were examined, all of them participated in the University Basketball Championship. A theoretical analysis of scientific literature sources and a pedagogical experiment were conducted. Mathematical statistics and pedagogical testing were used as methods. Results. Twelve tests were selected and checked for reliability that influenced most the physical fitness of basketball players in terms of strength, speed, jumping ability. Three hypothetical latent factors were identified that optimally determined the combination of these tests: “jumping ability / speed”, “explosive force/endurance”, and “strength”. Using factor analysis and an intercorrelation matrix, the most informative physical fitness tests were identified: standing vertical jump, 20 m shuttle run, pull-ups, which are used in the educational and training process of basketball players. Conclusion. The data obtained from the pedagogical experiment are of practical interest, primarily for trainers and university teachers. These tests do not require expensive equipment and can be performed in a gym, at the same time being the most informative in a limited time, which is typical for the educational and training process of students. This approach increases the efficiency of classes and optimizes the educational process. A comprehensive assessment of students will make it possible to track their health and physical fitness. Such data will allow adjusting the training process in the most effective way.

Abstract Background Different physical activities are widely recommended as non-pharmacological therapies to reduce blood pressure. However, the effectiveness of exercise programs is associated with its continuity and regularity, and the long-term adherence to traditional exercise interventions is often low. Recreational sports emerge as an alternative, being more captivating and able to retain individuals for longer periods. Besides, sport interventions have demonstrated improvements in physical fitness components that are associated with a lower incidence of hypertension. However, no studies have investigated the effects of recreational sports on 24 h ambulatory blood pressure. The aim of the present study is to evaluate the effect of beach tennis training on ambulatory blood pressure and physical fitness in individuals with hypertension. Methods This study will be a randomized, single-blinded, two-arm, parallel, and superiority trial. Forty-two participants aged 35–65 years with previous diagnosis of hypertension will be randomized to 12 weeks of beach tennis training group (two sessions per week lasting 45–60 min) or a non-exercising control group. Ambulatory (primary outcome) and office blood pressures, cardiorespiratory fitness, muscle strength/power and quality of life will be assessed at baseline and after the intervention period. Discussion Our conceptual hypothesis is that beach tennis training will reduce ambulatory blood pressure and improve fitness parameters in middle-aged individuals with hypertension. The results of this trial are expected to provide evidences of efficacy of recreational beach tennis practice on blood pressure management and to support sport recommendations for clinical scenario in higher risk populations.

Abstract Background Little is known about the progression of obesity from childhood to adolescence. This study aimed to longitudinally examine the obesity status in a cohort of children across their childhood and adolescence, and to identify the factors associated with persistent obesity. Methods The study used data from School Physical Fitness Award Scheme (SPFAS), a population-based programme in Hong Kong primary and secondary schools. Students were included if they participated in the SPFAS in both 2014 (Primary 1 and 2) and 2018 (Primary 5 and 6). Their anthropometric and physical fitness parameters were analyzed. Results A total of 18,863 students were included. The baseline prevalence of obesity was 5.7 %. After 4 years, the prevalence increased to 6.7 %. Among those with obesity at baseline, 35.3 % remained obese after 4 years. The addition of baseline physical fitness level did not improve the prediction for persistent obesity. Conclusions One-third of obese students in junior primary school remained to be obese into adolescence. Their baseline physical fitness level did not improve the predictive value for future obesity. Further studies should investigate the prognostic factors that may influence the natural course of childhood obesity.
