Skład ciała osób w różnym wieku z uwzględnieniem 60+ rekreacyjnie uprawiających pływanie

Wstęp: Artykuł prezentuje wyniki analiz dotyczących składu masy ciała ludzi w różnym wieku z uwzględnieniem osób 60+ uprawiających regularny trening pływacki. Cel: Celem pracy była analiza porównawcza składu ciała pomiędzy badanymi podzielonymi na grupy w różnym wieku. W związku z tak określonym celem sformułowano następującą hipotezę badawczą: osoby uprawiające pływanie w grupie Masters różnią się pod względem komponentów składu ciała w zależności od grupy wiekowej. Materiał: Badaniami objęto n=86 osób dorosłych, w tym 32 kobiet i 54 mężczyzn. Badania zostały przeprowadzone z zastosowaniem metody impedancji w oparciu o narzędzie jakim jest analizator składu ciała InBody 270. Dokonano analizy ośmiu wskaźników dotyczących komponentów ciała osób uprawiających pływanie w grupie Masters. Wyniki: Uzyskane wyniki wykazały, iż u kobiet parametry składu ciała wraz z wiekiem nieznacznie się zmieniają. W porównywanych grupach prezentują się na zbliżonym poziomie. Odmiennie jest w grupie badanych mężczyzn, w której, wskaźniki PBF (Procent tkanki tłuszczowej), FFM (Masa beztłuszczowa) prawego ramienia FFM (Masa beztłuszczowa) lewego ramienia, BFM (Masa tkanki tłuszczowej) lewego ramienia, BFM% (Masa tkanki tłuszczowej) lewego ramienia, poziom tłuszczu wisceralnego, jak również wynik InBody wykazały różnice istotne statystycznie. Wnioski: Wśród osobników płci męskiej, wraz z wiekiem, narasta zróżnicowanie pod względem ogólnej zawartości tkanki tłuszczowej, jak również pogłębiają się różnice w jej anatomicznym rozmieszczeniu mierzone za pomocą wskaźników dystrybucji. U badanych mężczyzn, dysproporcja wartości analizowanych parametrów była znaczna i określała zawartość tkanki nieaktywnej, stawiając grupę mężczyzn po sześćdziesiątym roku życia jako tę o zwiększonej zawartości tkanki tłuszczowej.Introduction: The article presents the results of a study analyzing body composition in different age groups, including 60+ seniors who regularly participate in swimming training. Study aim: The aim of this study was to compare the body composition of adults divided into different age groups. The research hypothesis postulating that Masters swimmers are characterized by age-dependent differences in body composition was tested. Materials and Methods: A total of 86 adults, including 32 women and 54 men, participated in the study. Body composition was determined by bioelectrical impedance with the InBody 270 analyzer. Eight body composition parameters were evaluated in Masters swimmers. Results: The results revealed minor age-related changes in the body composition of female participants. The analyzed parameters were similar in the compared groups of females. In contrast, significant differences in percent body fat (PBF) values, right-arm fat free mass% (FFM%) values, left-arm FFM% values, left-arm body fat mass% (BFM%) values, left-arm BFM values and visceral fat level were observed among the surveyed males. Conclusions: In men, the differences in Percent Body Fat and the anatomic distribution of adipose tissue measured with the relevant indicators increased with age. In male participants, considerable disproportions were observed in the content of inactive adipose tissue, and the accumulation of adipose tissue was higher in men older than 60

Effects of exercise of different intensity on gut peptides, energy intake and appetite in young males

Introduction and research aims: The aim of the work was an evaluation of the impact of physical exertion on the regulating of food intake and digestive system hormone release as well as the partly connected phenomenon of evaluating the subjective sensation of hunger and the amount of food consumed at various time following physical exercise. Materials and methods: The tests covered 12 young, healthy men, for whom the effects of physical exertion of a moderate and high intensity on the subjective sensation of hunger/satiety, evaluated by means of visual analogue scales, on food intake as well as on the metabolic and hormonal parameters were tested. Results: Physical exertion resulted in a fall in the subjective sensation of hunger, but only following intensive exertion was this statistically significant. The intake of food was greater after exertion when compared to the control group. Moderate exertion resulted in a statistically significant but short-lived increase in the ghrelin level. This effect was not observed after intensive exertion, while in those tests during the post-meal period there occurred a fall in the concentration of ghrelin in the plasma. After exertion a physical fall was observed in the concentration of insulin in the plasma, for the intake of food resulted in a notable increase in its level. Conclusions: Physical highly intensive exertion, results in a temporary reduction in the subjective sensation of hunger but leads to an increased food intake. The current research suggests that moderate but not intensive physical exertion stimulates the secretion of ghrelin

Biomechanical aspects of the foot arch, body balance and body weight composition of boys training football

Background: The aim of the study is to assess the body balance and podological parameters and body composition of young footballers in the context of the control of football training. Methods: The study examined the distribution of the pressure of the part of the foot on the ground, the arch of the foot, and the analysis of the body composition of the boys. The pressure center for both feet and the whole body was also examined. The study involved 90 youth footballers from Olsztyn and Barczewo in three age groups: 8–10 years, 11–13 years old, and 14–16 years. The study used the Inbody 270 body composition analyzer and the EPSR1, a mat that measures the pressure distribution of the feet on the ground. Results: The results showed statistically significant differences in almost every case for each area of the foot between the groups of the examined boys. The most significant differences were observed for the metatarsal area and the left heel. In the case of stabilization of the whole body, statistically significant differences were noted between all study groups. In the case of the body composition parameters, in the examined boys, a coherent direction of changes was noticed for most of them. The relationships and correlations between the examined parameters were also investigated. The significance level in the study was set at p < 0.05. Conclusions: Under the training rigor, a statistically significant increase in stability was observed with age. The total length of the longitudinal arch of both feet of the examined boys showed a tendency to flatten in direct proportion to the age of the examined boys. Mean values of the body composition parameters reflect changes with the ontogenetic development, basic somatic parameters (body height and weight) and training experience, and thus with the intensity and volume of training. This indicates a correct training process that does not interfere with the proper development of the body in terms of tissue and biochemical composition

Podiatric and stabilographic examinations of the effects of school bag carrying in children aged 11 to 15 years

Background: The issues raised in this study were inspired by the concern for the musculoskeletal status of school children. Carrying excess weight in the form of a school bag in this period of life affects the correct body posture of school children. The aim of the study was to analyze the influence of school bags on the feet force distribution on the ground and postural balance in children of both sexes between 11 and 15 years of age. Methods: The study investigated the distribution of pressure forces on the sole of the foot and its arch. The center of pressure for both feet and the whole body was also examined. The participants were 100 students from primary schools in Gdańsk, aged 11 to 15, including 54 girls and 46 boys. The research used a podobarographic platform that measures the distribution of foot pressure to the ground. The examinations included two measurements: in the first, the children stood on the platform in a natural position. Then, a 5 kg backpack was put on and they stood on the platform again. Results: Statistically significant differences were found in the distribution of the foot pressure on the ground in the left metatarsus (p = 0.000) and heel (p = 0.000) after putting on the backpack in both girls and boys. However, in the right foot, these differences concerned the metatarsal area (p = 0.001). The results of the balance tests were only statistically significant in the group of girls in the right foot sway area (p = 0.020). Conclusions: The school backpack load led to an increase in the values of the heel and metatarsal area measured in the students, causing its flattening

The effect of programed physical activity measured with levels of body balance maintenance

BACKGROUND: The aim of the research was an evaluation of 2 training programs covering the same standard physical activity in the initial stage (warm-up) and the main (motor exercises) as well as a separate end part in Program A of stretching and in Programme B of vibration training designed to improve the level of body balance. MATERIAL/METHODS: We tested 40 randomly chosen students of the Academy of Physical Education and Sport in Gdansk, subsequently divided into two 20-person groups: C (average age 21.3±1.2), and E (average age 21.8±1.1). The training of body balance was conducted for 8 weeks: we used in Group C Program A and in group E Program B. The evaluation of body balance was done 3 times: at the beginning, at midway point, and at the end of the experiment. The stabilographic tests with posture-graphical method and the task of 1-leg balance standing with eyes closed was used. RESULTS: It was found that in the first examination both groups did not significantly differ in terms of the tested parameters of balance. During the training process we obtained increased time of maintaining balance on 1 leg. This difference was significant between tests 1 and 2 both for Group C (p=0.0002) and for E (p=0.0034), while between the tests 2 and 3 in Group E (p=0.0213) only. CONCLUSIONS: The training Program B is more effective to maintain balance on 1 leg when compared to Program A
