Purpose: The aim of our study was to translate the Aberdeen Varicose Vein Questionnaire (AVVQ) into Hungarian, and to investigate the validity and reliability of the Hungarian AVVQ, as well as to assess the health-related quality of life in patients with varicose veins of the leg. Methods: 374 adults participated in this study who were divided into two groups (varicose vein, healthy). We analyzed internal consistency, convergent validity (using the 36-Item Short Form Survey, SF-36), repeatability, and intra-class correlation coefficient of the Hungarian AVVQ. Regarding discriminant validity, we determined the scores of the Hungarian AVVQ in both groups using the Mann-Whitney U-test. Results: The Cronbach-alpha value was 0.890, while the correlation coefficient was R = 1.000. According to the results of the convergent validation, the scores of pain and dysfunction moderately correlated with some scores of the SF-36. The score of cosmetic appearance had a relationship with many scores of the SF-36. We registered a significant relationship between the score of extent of varicosity and some scores of the SF-36. There was significant correlation between the score of complications and numerous scores of the SF-36 (physical functioning, role limitations due to physical health, pain and general health). The score of pain and dysfunction, cosmetic appearance, extent of varicosity, complications and total score of the Hungarian AVVQ showed a significant difference between both groups. Conclusions: The Hungarian AVVQ was a reliable and a valid tool to assess the health-related quality of life among patients with varicose veins and was a useful tool to justify the further treatment of the patients.

Background: The aims of our study were to investigate the changes in anthropometric and physical parameters and fasting hormonal levels among pre-pubertal female handball players (n = 14, age: 11.53 ± 0.58 yrs, height: 153.36 ± 5.12 cm, body mass: 43.59 ± 6.14 kg) in the pre-season period following 8 weeks of handball training, and to analyze the contribution of hormones, physical performance and anthropometric parameters. Methods: Prior to and immediately following the training period, several anthropometric, strength, and cardiorespiratory variables, including fasting hormonal concentrations (plasma cortisol, estradiol, testosterone and growth hormones) were measured. Athletes performed concurrent resistance and aerobic exercises, including game-based trainings during the 8-week training period. Results: Significant elevations were found in all strength parameters (maximal handgrip strength dominant (D): 16.40%, p < 0.01; non-dominant (ND): 25.15%, p < 0.05; maximal concentric (MVC) torque of quadriceps D: 13.82%, p < 0.05; ND: 12.61%, p < 0.05; MVC torque of hamstring D: 12.14%, p < 0.01; ND: 12.44%, p < 0.01), including plasma cortisol levels (C, 34.30%, p < 0.05) and peak respiratory quotient (5.24%, p < 0.05). Body composition and maximal oxygen uptake (VO_2max) remained unchanged. Percentage changes in thigh (r = 0.316, p < 0.05), hand (r = 0.361, p < 0.05), and hip circumference (r = 0.297, p < 0.05) correlated with C changes. Percentage changes in plasma growth hormone levels (GH) contributed to the magnitude of gains in handgrip strength (r = 0.553, p < 0.05). Percentage changes in maximal exercise pulmonary ventilation (MVE) correlated with elevated C (r = −0.592, p < 0.05). Discussion: Changes in anthropometric variables and fasting hormone levels (estradiol, testosterone and cortisol) were poor indicators of developing VO_2max and strength during pre-pubertal years. Physical adaptation may not be explained in consideration of the athletes’ hormonal or anthropometric characteristics. Conclusion: Gradually increased training volume followed by a summer break should be applied to youth handball, considering the anti-hypertrophic responses and the inhibitory effect of elevating C on pre-pubertal maturation.

The aim of our study was to investigate the effects of a 24-week-long training program on changes in static body posture, as well as the characteristics of anterior shoulder pain in youth swimmers, and the relationship between changes in whole-body posture and the frequency and intensity of anterior shoulder pain. Competitive young swimmers (n = 54, 13.9 ± 1.79 years) were divided into experimental group and control group and both groups performed their usual swimming training. In addition, the experimental group performed a 24-week-long whole-body posture correction program. Before and after the implemented training, whole-body posture was analyzed using the PostureScreen (version 13.7) mobile application, and subjective intensity of pain was determined using the swimmer’s functional pain scale. Significant changes were found between the two groups in numerous measured postural parameters. A significant reduction in the prevalence of shoulder pain and score of the pain scale was observed after the posture correction program in the experimental group. Our results may imply that more optimal biomechanical conditions may indirectly reduce the incidence of swimmer’s shoulder in terms of prevention. Analysis and monitoring of body posture of swimmers using an on-field mobile application continuously, and the application of preventive training programs, may help to avoid developing injuries.

Aim The aim of the study was to investigate acute and chronic effects of a two-week eccentric concentric, dynamometric training concerning the time-course changes of blood antioxidant parameters (total antioxidant capacity, catalase enzyme activity, thiol concentration), and to compare the adaptability of young and older muscle to this type of training. Methods Seventeen moderately trained young and older men participated in this research. Subjects performed six eccentric concentric exercise bouts during the training period and maximal voluntary isometric contraction torque, plasma CK and intensity of muscle soreness were determined before and 24 h after the first exercise. During five testing sessions (baseline, 24 h, 48 h, week 1, week 2) the level of blood antioxidants were measured. Results No significant changes were registered in total antioxidant capacity and catalase enzyme activity for any time points; furthermore, no difference was found between groups during the training period. However, total thiol concentrations measured two weeks after the first exercise bout significantly differed between the young and elderly groups. Plasma CK and the subjective intensity of soreness elevated significantly 24 h following the first training, while maximal voluntary isometric contraction torque decreased at the same time. Conclusions Our results do not support previous findings that chronic, short-term eccentric concentric training programs enhance the antioxidant defense of well-trained older and young men. This type and setting of exercise did not cause a different time course of changes in the markers of exercise-induced muscle damage (EIMD) in the studied population. Subjects may already have adapted to maintain constant levels of antioxidants and isometric torque due to their active lifestyle.

Purpose: The number of injuries among junior footballers is extremely high. Adolescent footballers may be at particularly high risk due the changes during fast growth period. Their poor posture could be in association with incidence of injuries. Our aim was investigate the relationship between poor posture and injury characteristics of youth football players. Methods: One hundred and sixteen football players ( n = 116, age range 11–18 years) were studied. We grouped our subjects by age group and academic group. A questionnaire and injury registration software were used to assess training and injury‐related data. Habitual posture was analysed using the PostureScreen mobile application. Results: Injury rates were high in the overall study population, typically highest in the U14 and U15 age groups. Significant positive correlations were found between several postural parameters and injury characteristics. Less significant correlations were observed according to academic grouping. Conclusions: There is a clear relationship between postural parameters measured in the frontal and sagittal planes and injury incidence in youth football players. Level of Evidence: Level III.

The purpose of the present study was to examine the anthropometric parameters and cardiopulmonary functions of young handball players in different playing positions. 15 male handball players from first division (mean age: 16.06±0.63 yrs) participated in our research who were divided by their playing positions. First anthropometric parameters, body composition and pulmonary functions in rest were measured. Then physiological changes of the players were tested with Bruce protocol. We found that wings differed the most in morphological characteristics from other players. We did not find significant differences in pulmonary functions among positions. The highest values of Tidal volume in the vita maxima test were found in pivots (2.82±0.15 l) which is significantly higher than Tidal volume of goalkeepers (p=0.006). The highest mean value of maximal oxygen uptake was recorded (73.93±9.41 ml/kg/min) in wings. Altogether in our study important differences were seen in physique and in performance also among young handball players.
