European fitness landscape for children and adolescents: updated reference values, fitness maps and country rankings based on nearly 8 million test results from 34 countries gathered by the FitBack network.

OBJECTIVES: (1) To develop reference values for health-related fitness in European children and adolescents aged 6-18 years that are the foundation for the web-based, open-access and multilanguage fitness platform (FitBack); (2) to provide comparisons across European countries. METHODS: This study builds on a previous large fitness reference study in European youth by (1) widening the age demographic, (2) identifying the most recent and representative country-level data and (3) including national data from existing fitness surveillance and monitoring systems. We used the Assessing Levels of PHysical Activity and fitness at population level (ALPHA) test battery as it comprises tests with the highest test-retest reliability, criterion/construct validity and health-related predictive validity: the 20 m shuttle run (cardiorespiratory fitness); handgrip strength and standing long jump (muscular strength); and body height, body mass, body mass index and waist circumference (anthropometry). Percentile values were obtained using the generalised additive models for location, scale and shape method. RESULTS: A total of 7 966 693 test results from 34 countries (106 datasets) were used to develop sex-specific and age-specific percentile values. In addition, country-level rankings based on mean percentiles are provided for each fitness test, as well as an overall fitness ranking. Finally, an interactive fitness platform, including individual and group reporting and European fitness maps, is provided and freely available online (www.fitbackeurope.eu). CONCLUSION: This study discusses the major implications of fitness assessment in youth from health, educational and sport perspectives, and how the FitBack reference values and interactive web-based platform contribute to it. Fitness testing can be conducted in school and/or sport settings, and the interpreted results be integrated in the healthcare systems across Europe.

Functional fitness normative values for elderly polish population.

BACKGROUND: It's really important to measure the actual functional physical fitness of elderly independent living persons from different environments to know the level and rate of decrease may inform about the threat of loss of functional independence, hence the need to monitor and assess the senior's motor realm and adapt to it the appropriate programs and treatments in the care for the elderly person. METHODS: The study involved 5367 people (mean age 69,63 ± 7,06), including 4164 women (mean age 69,55 ± 7,11) and 1203 men (mean age 69,91 ± 6,86) aged 60 to 93 years old. We have measured basic anthropometric features and physical fitness (by using Senior Fitness Test). RESULTS: The average values in individual SFT tests significantly decrease along with age. After age of 80 and 85 there were no sex differences in SFT. The largest deficits concern the dynamic balance and the decrease reaches 69% in men and 62% in women A significantly higher rate of decline in aerobic capacity concerns men (43%) than women (36.9%). A clearly lower rate of loss occurs in the muscular strength of the lower and upper body and does not exceed 30%. CONCLUSIONS: The results are of great clinical importance for the development of effective prevention and gerontological education programs in terms of promoting active lifestyle and successful ageing, at the same time limiting the economic consequences of treatment and hospitalisation.

Percentile Values of Physical Fitness Levels among Polish Children Aged 7 to 19 Years--a Population-Based Study.

AIM: The objective of the study was to report gender and age-specific percentile values for fourteen commonly used field-based physical fitness tests among a national representative sample of Polish children aged 7 to 19 years. METHODS: A descriptive cross-sectional and population-based study examines the physical fitness among a random and large national representative sample of schoolchildren aged 7 to 19 years in Poland. A sample of 49,281 children and adolescents (25,687 boys and 23,594 girls) was assessed by the EUROFIT fitness test battery, the International Committee on the Standardization of Physical Fitness Tests and Cooper Test of physical fitness. The LMS statistical method was used. RESULTS: Smoothed gender and age-specific percentiles for the physical fitness tests in boys and girls aged 7 to 19 years are reported and expressed as both tabulated and curves values (2.3rd, 9th, 25th, 50th, 75th, 91st, and 97.7th). Figures showed greater physical fitness levels in boys, except for the flamingo balance, sit-and-reach, and stand-and-reach tests, in which girls performed slightly better. There was also a trend towards increased physical fitness levels as the age increased in both boys and girls. CONCLUSION: The percentile values provided will enable the correct interpretation and monitoring of fitness status of Polish children.

[Physical fitness in relation to age and body build of young chess players]. / Sprawnosc fizyczna a wiek i budowa ciala mlodych szachistów.

INTRODUCTION: Specificity of chess training promotes sedentary lifestyle and may reduce chess players participation in different physical activities. Limited physical activity leads to decrease of physical fitness and may augment the risk of overweight and obesity. It is suggested that these athletes will characterize more frequently lower physical fitness and weight/height proportions disorders. The aim of the study was evaluation of physical fitness and its relationship with age and body build of athletes. MATERIAL AND METHODS: A sample of 73 individuals (35 girls--48% and 38 boys--52%) aged 8-19 years took part in this study. All competitors were members of national team and Polish representatives for the European and world chess championship. Chess players' physical fitness was measured by EUROFIT tests. RESULTS: With reference to the Polish population chess players characterized higher level of physical fitness. In six tests of EUROFIT chess players had better standardized results than controls. Sit ups (mean standardized result 0.842), shuttle run 10 x 5 m (0.577), standing broad jump (0.552) and flamingo balance (0.371) were very well performed by chess players. Only in one test, bent arm hang, sportsmen achieved worse results (-0.719). Permanent decrease of chess players' physical fitness with age was also observed. CONCLUSIONS: Although chess players' physical fitness was satisfied in comparison to age-matched control, it is recommended to include in their training more exercises developing strength. Because of changes in body build with age and decrease of physical fitness, chess players ought to participate in regular physical activity. Therefore chess organisers should provide the variety of active forms that can be chosen by competitors in their leisure time.

[Nutritional habits of young chess players]. / Nawyki zywieniowe dzieci i mlodziezy grajacych w szachy.

INTRODUCTION: Proper nutrition plays significant role in children's development and health protection in adults, as well. Therefore such a study is extremely important particularly among youth population. It is well known that adequate nutrition also helps to achieve high sport results. The aim of the study was the nutritional habits evaluation of young chess players. MATERIAL AND METHODS: A total of 75 chess players aged 8-19 years took part in the study. Among them there were 36 girls (48%) and 39 boys (52%). Subjects belonged to the Polish Chess Academy, medalists of the Polish, European and world youth championships and members of the Polish national team. Used questionnaire allowed to collect data about regular diet of young athletes. RESULTS: Recommended number of 4-5 meals per day was consumed only by 55% persons. Another observed disadvantageous nutritional habit among responders was missing first breakfasts (75%), especially during competitions. Less than half of subjects declared regular meals intake during the day (from 25 to 43%). Moreover, it was noticed, that 13,3% chess players ate vegetables and fruits only one time per day. Sweets were taken at least one time per day by 22 to 50% participants. CONCLUSIONS: Due to numerous nutritional mistakes in studied population it is compulsory to conduct nutritional education among athletes and among their parents and coaches as well.

The effectiveness of phonophoresis with ketoprofen in the treatment of epicondylopathy.

Background. This article examines the therapeutic effects of phonophoresis with ketoprofen in gel form in patients with enthesopathy of the elbow. Ultrasonic therapy and phonophoresis have their primary application in the physical therapy of this disorder. The main aim of this study was to assess the effectiveness of phonophoresis. Material and methods. The research group consisted of 19 patients diagnosed with enthesopathy of the lateral and medial epicondyle. In the statistical analysis we included 28 elbow joints treated with phonophoresis. The effects of therapy were compared with a control group of 20 patients who were treated with only ultrasound therapy. The therapeutic series consisted of 10 treatments, using the pulse mode of ultrasound and an intensity of 0.8 W/cm2 in both groups. The clinical examination (objective assessment) and interview (subjective assessment) consisted of specific tests, and were separately collected. Reasults. The positive effects of phonophoresis using a pharmacologically active gel with ketoprofen were shown to be highly significant in both assessments, objective and subjective. The pain symptoms in the elbow resolved in most of the patients. There were statistically significant differences between phonophoresis and ultrasound therapy. Conclusions. Our results support the application of phonophoresis with ketoprofen in the treatment of epicondylitis.
