Study aim: to compare the physical fitness of bus drivers and fare collectors (working hours per day in sitting position = 7h) with and without low back pain. The subjects consisted of sixty-six bus drivers and fare collectors working in a public transport company. Material and methods: the prevalence of low back pain, age and working time was determined for bus drivers and fare collectors using a questionnaire. All subjects underwent anthropometric assessment (weight, height and waist circumference), an abdominal endurance test and a hip flexibility test. Results: there was a significant difference between the low back pain group (n = 27) and the group without pain (n = 39) in body mass index (27.5 ± 3.9 kg · m–2 vs. 25.6 ± 4.0 kg · m–2), waist circumference (92.5 ± 10 cm vs. 85.9 ± 9 cm), the abdominal endurance test (28.9 ± 17.5 repetitions vs. 38.4 ± 19.2 repetitions) and the hip flexibility test (69.1 ± 14.4 degrees vs. 78.3 ± 16.9 degrees). There was no significant difference in age and working time. Conclusion: anthropometric measures, abdominal endurance and hip flexibility are deficient in bus drivers and fare collectors with low back pain. We suggest that workers with prevalent low back pain increase their physical fitness.

Study aim: To find out whether the ability to accelerate, decelerate and turn may contribute to the performance of young football players during the Yo-Yo Intermittent Endurance Test - Level 2 (YYIEL2).Material and methods: A group of 239 young male football players from three age categories: under 15 years (U15; n = 102), under 17 years (U17; n = 59) and under 19 years (U19; n = 74) were evaluated in sprint, agility, and intermittent exercise performance. Multiple regression models weighted for maturity status were applied.Results: Significant (p<0.001) differences were found between the U15 and both other groups in all tests. The YYIEL2 was significantly correlated with 5-m and 30-m sprints and agility (r = 0.361, 0.499 and 0.555, respectively; p<0.001) and the latter 3 variables explained 31% (p<0.001) of the total variance of the YYIEL2 performance, the agility test alone being the strongest predictor (b = 0.56; p<0.001).Conclusions: Despite the usefulness of the YYIEL2 test used in football to determine aerobic fitness, other factors than O2max, such as peripheral limitations and the ability to accelerate, decelerate and turn, may influence the performance during the test.

Study aim: To compare two exercise training modes on the physical fitness of 10 year-old children. Material and methods: A sample of 60 schoolboys aged 10 years were randomly divided into 3 groups: Traditional (TG), trained according to the Brazilian national curricular parameters, Maturational (MG), in which the degree of difficulty of the activities was adjusted to the level of maturity of subjects, and Control group (CG). The Greulich-Pyle protocol was used to assess biological maturity. The following fitness tests were applied: 5x10 m shuttle run (SHR), Burpee's test (BCT), goniometric (LABIFIE) measurement of shoulder joint flexibility (SAA), horizontal shoulder flexion (HSF), shoulder joint abduction (SJA), lumbar spine flexion (LSF), hip joint extension (HJE) [10], Sargent's Jump Test (SJT), endurance shuttle run (ESR) and 50-m run. The TG and MG groups trained 16 weeks, twice weekly.Results: The only significant (p<0.05) between-group differences were found for SJA (TG>MG) and LSF (TG>CG).Conclusions: Despite the lack of clear-cut results, biological maturation combined with chronological age should be considered when applying various methodological approaches in order to encourage the engagement in physical exercises as this would have favourable carry-over effects.

Study aim: To assess the generation changes in somatic and motor variables in menstruating and non-menstruating girls from Eastern Poland.Material and methods: Two cohorts of girls aged 10 - 15 years from Eastern regions of Poland were studied in 1986 (n = 2554) and in 2006 (n = 5563). The age at menarche was determined in girls by probit method employing the status quo technique. The girls were subjected to the International Physical Fitness Test battery and the results were classified into two categories: those of girls who already menstruated (M) or who have not yet (N).Results: Mean menarcheal age significantly (p>0.001) decreased in 2006 compared with 1986 (12.77 and 13.41, respectively). This was accompanied by marked, significant increases in body height, significant changes in body mass and significant increases in the slimness. Physical fitness generally decreased, especially in girls aged over 12 years, but in the handgrip and in sit-ups significant improvements were noted in both groups of girls.Conclusions: The results seem to support the view that the secular advancement of somatic traits was associated with decreasing physical fitness.

Study aim: To evaluate the effects of the ‘Menopause-in-Shape Programme’ on physical fitness of elderly women.Material and methods: A group of 323 elderly women lodged in the House for the Elderly participated in a 10-month programme (dancing or walking) and formed the experimental group. Another group of 289 elderly women (control) were sedentary throughout the study. All of them aged 60 - 89 years. Both groups were subjected to the Fullerton Functional Fitness Test battery: chair stand test (CST), arm curl test (ACT), 6-min walk test (6-WT), 2-min step test (2-ST), chair sit and reach test (SRT), scratch test (SCT) and 8-foot up and go test (8-UG).Results: In the experimental group, improvements were noted in CST (by 11.7%; p<0.001), ACT (by 9%; p<0.001), 2-ST (by 2.2%; p<0.001) and 8-UG (by 0.4%; p<0.05) but not in somatic variables. No significant changes were noted in the control group.Conclusions: The Menopause-in-Shape Programme is an efficient tool in improving physical fitness of elderly women even if no somatic effects can be expected.

Objectives: The objective of this work was to study the relationship between body image and muscle strength in Spanish children and adolescents. Methods: 230 Spanish school children participated (104 boys and 126 girls), between 3 and 15 years old with an average age of 9.05 ± 3.10 years. The body image was measured by the Stunkard silhouettes. The level of muscular strength was evaluated by manual dynamometry (Takei TKK 5101 dynamometer). The statistical analysis was carried out with SPSS 23.0. Findings: Significant positive correlations were found between the current body image and the level of muscular strength of the dominant side (r = 0.182, p=0.027), non-dominant side (r=0.155, p = 0.002), and average strength (r = 0.171, p = 0.015) of Spanish schoolchildren. According to sex, significant correlations were found between body image and strength in both boys and girls. According to age, the significant correlations between body image and strength were found in the Secondary Education group (12-15 years). Conclusions: The results of this study show that muscle strength can be a determining factor in the perception of body image of children and adolescents. It is recommended to carry out intervention programs with the aim of improving strength, because this will have positive effects on the body image of the participants.

The objectives of this study were to examine (a) the prevalence of overweight/obesity, (b) the relationship between body mass index (BMI) and body fat percent (BF), and (c) the association between BMI, BF and power output in adult male soccer players. Members of competitive soccer clubs (n=169, aged 22.7±4.2yr) were examined for anthropometric characteristics and body composition, and performed the physical working capacity in heart rate 170 min−1 test (PWC170), a force-velocity test (F-v) and the Wingate anaerobic test (WAnT). Based on international BMI cut-off points, 17.8% (n=30) of participants were classified as overweight. BMI was correlated with BF (r=0.67, p<0.001) and could be predicted based on the equation BF=1.193·BMI-12.24 (standard error of estimate 2.49). BMI and BF were in inverse relationship with mean power during WAnT (r=−0.30, p<0.001; r=−0.47, p<0.001, respectively). BF was also in inverse relationship with PWC170 (r=−0.26, p<0.001) and maximal power of the F-v test (r=−0.18, p=0.020).The prevalence of overweight among participants was lower than what is observed in general population. The findings confirmed previous observations on general population about the negative effect of overweight and fatness on selected parameters of physical fitness.

Study aim: To explore how elderly people with different living conditions are characterized by their fitness, body composition, and quality of life.Material and methods: Women aged 60 years and over (n = 60; age = 76.2 ± 7.6 years) were examined in cross-sectional study from a medium-sized city in western Hungary. Participants were chosen from a twilight home (n=27, age = 79.4 ± 7.7years) and clubs for retired people (n = 33, age = 73.7 ± 6.6 years). Physical fitness status was assessed by Fullerton Functional Fitness Test - Senior Fitness Test (FFFT); body composition (BC) with Inbody-720 bioelectrical impedance spectroscopy; and quality of life with WHOQOL-OLD questionnaire. Data were analysed with the use of t-test for independent samples and stepwise discriminant analysis.Results: FFFT shows significant differences in each variable: lower and upper body strength, aerobic endurance, upper and lower body flexibility, and dynamic balance. These variables were significantly higher in the clubs for retired people. The BC of twilight home residents was significantly lower in height and fat-free mass. Regarding quality of life, there were significant differences in perception, autonomy, and sociability for the favour of elderly in clubs; however, there were no differences in activities of past, present and future, or differences in attitudes towards death or intimacy.Conclusions: A sedentary and institutionalized lifestyle with little variety in daily activity and programing has a negative effect on physical fitness status, body composition, and quality of life. Self-motivation, active lifestyle, and regular and varied programs seem to have leading roles in the quality of life in elder population.

Study aim: To assess the size of secular trends in the physical fitness of boys from eastern Poland taking into consideration stages of education. Material and methods: The physical fitness results of boys aged 7-19 years living in eastern regions of Poland were analyzed: 3188 students were examined in 1986 while in 2006 the research included 10 810 boys. In both examinations (1986 and 2006), the level of motor abilities was measured according to the guidelines of the International Physical Fitness Test. The individual results of children and youth examined in 2006, which took into account calendar age, were converted into points on a T scale, with means and standard deviations from 1986 accepted as norms. On the basis of the obtained point values and taking into account stages of education (7-9 – integrated teaching, 10-12 – primary school, 13-15 – lower-secondary school, 16-18 – upper-secondary school), arithmetic means and dispersion values concerning motor abilities in the groups were calculated. Individual results in motor abilities of every subject were used to define quantitative generation changes. Differences between the means obtained in 1986 and 2006, as well as between the fractions of boys qualified for respective fitness category in both examinations, were assessed. Results: Over the 2-decade period the boys from eastern Poland slightly improved their results only as far as sit-ups are concerned (1.47 points), while the level of bent arm hang, handgrip, 50 m run, and shuttle run 4×10 m remained the same. In contrast, negative changes were observed in the long run (4.44 points), the sit-and-reach test (4.47 points), and the standing broad jump (3.74 points). The greatest decline in motor abilities was noted amongst schoolchildren from integrated education classes (2.69 points); whereas the smallest decline was noted in adolescents from lower secondary schools (0.60 points). Conclusions: The changes noted in physical fitness indicate that in the context of health the revision of the Act on Physical Culture from 2002, which reduced the number of school’s physical education classes, is a debatable issue.

Body build and physical fitness of schoolchildren of low socioeconomic strata from urban and rural areas of Yucatan were studied. The material consisted of 552 children from Merida (the capital city of Yucatan State, Mexico) and of 526 children from the Yaxcaba horticultural community, 7 through 14 years of age. These are cross-sectional samples studied in 1996-97 in Merida and in 1999 and 2000 in Yaxcaba. The ethnic origin was evaluated using two surnames of children (from the father and mother side). The studied variables included stature, BMI, arm circumference, grip strength, agility run, Sargent vertical jump index (explosive strength), spine flexibility index, and reaction time. Urban children are significantly taller than rural ones, and BMI and arm circumference show also a tendency to be greater in urban areas. Physical fitness tests are better performed (better results) in rural areas than in urban ones. If the whole material is divided according to two ethnic groups (Mayas and Mestizos, and Creoles) the differences in body build are still observed but those in physical fitness disappeared. Creole children are taller than Mayas and Mestizos and they show a tendency to have more weight for height and greater arm circumference. Generally, the differences in physical fitness are only observed between rural and urban children what may be caused by a more active way of life in villages than in towns resulting from agricultural activity. However, differences in stature are observed between ethnic as well as between rural and urban groups. This may have the genetic origin (Creoles and Mayas), and in the case of different localities, it may also be caused by more various nutrition in towns than in villages.
