Sauna-Induced Body Mass Loss in Young Sedentary Women and Men

The aim of the study was to evaluate the relationship between body mass index (BMI) and body mass loss (BML) induced by thermal stress in a dry sauna. The study was conducted on a group of 674 sedentary students, 326 women and 348 men aged 19-20. The correlations between BMI scores and BML were determined. The subjects were placed in supine position in a dry sauna for two sessions of 10 minutes each with a 5-minute break. The influence of BMI on the amount of BML in the sauna was determined by nonlinear stepwise regression. The smallest BML was noted in underweight subjects; students with normal weight lost more weight, whereas the greatest BML was reported in overweight and obese subjects. Persons with a high BMI are at higher risk of dehydration, and they should pay particular attention to replenishing fluids during a visit to the sauna. The proposed equations for calculating BML based on a person's BMI can be useful in estimating the amount of fluids that should be replenished by both men and women during a visit to a dry sauna

RELATIONSHIPS BETWEEN SOMATIC FEATURES, SPEED ABILITIES AND CHANGES IN HEART RATE FOLLOWING SHORT-TERM PHYSICAL ACTIVITY IN YOUNG WOMEN AND MEN

Cel: Celem pracy jest określenie związków między cechami antropometrycznymi (masa ciała, wysokość ciała, długość kończyn dolnych i górnych) i BMI a poziomem zdolności motorycznych młodych kobiet i mężczyzn, w teście skiping z klaskaniem – 8 s (8s-SHC). W badaniach analizowano także zmiany w zakresie HR oraz zróżnicowanie płciowe badanych pod względem rozwoju somatyczno-motorycznego. Materiał i metody: W badaniach uczestniczyło 102 studentki i 108 studentów (wiek odpowiednio: 19,40 ± 0,493 lat i 19,57 ± 0,497 lat) Uniwersytetu Warmińsko-Mazurskiego w Olsztynie (UWM). U badanych dokonano pomiaru masy i wysokości ciała oraz długości kończyn dolnych i górnych, a na ich podstawie obliczono BMI. Poziom zdolności szybkościowych zbadano przy pomocy 8s-SHC. Dodatkowo zmierzono HR przed i po wysiłku oraz obliczono jego przyrost i spadek. Dla wszystkich badanych cech obliczono podstawowe charakterystyki statystyczne oraz współczynniki korelacji przy zastosowaniu nieparametrycznego testu U Manna-Whitneya pomiędzy cechami antropometrycznymi, HR i wynikami uzyskanymi w 8s-SHC. Wyniki: Mężczyźni charakteryzują się istotnie wyższymi (p<0,01) wartościami cech antropometrycznych (masa ciała, wysokość ciała, długość kończyn dolnych i górnych) oraz wykonują istotnie więcej klaśnięć od kobiet w teście 8s-SHC (odpowiednio: 25,95 ± 2,111 i 23,98 ± 2,068 klaśnięć, p<0,01). Liczba klaśnięć wykonywanych podczas 8s-SHC oraz wartości HR maleją istotnie wraz ze wzrostem wysokości i masy ciała oraz BMI. Wnioski: Wzrost wielkości ciała wpływa istotnie negatywnie na poziom zdolności szybkościowych u młodych kobiet i mężczyzn w teście 8s-SHC.Aim: The aim of the study is to determine relationships between anthropometric characteristics (body weight, body height, and length of upper and lower limbs), the BMI and the level of motor abilities of young women and men in the 8-second skipping with hand clapping test (8s-SHC). In the research, changes in the HR and gender the somatomotoric development were also analyzed. Material & Methods: In the research 102 female and 108 male students of University of Warmia and Mazury in Olsztyn participated (aged 19.40 ± 0.493 and 19.57 ± 0.497 respectively). In the study, the participants' body mass, body height and the length of upper and lower limbs were measured. On the basis of the measurements, the BMI was calculated. The speed abilities were analyzed with the use of the 8s-SHC. Additionally, the HR before and after the physical effort was measured and its increase and decrease were calculated. For all analyzed indicators, the descriptive statistics and the correlation coefficients between the anthropometric features, the HR and the results gained in the 8s-SHC were calculated with the use of the nonparametric Mann–Whitney U test. Results: Men are characterized by significantly higher (p<0.01) values of anthropometric features (body mass, body height, the length of upper and lower limbs) and they perform significantly more hand clapping than women in the 8s-SHC (25.95 ± 2.111 and 23.98 ± 2.068 of hand clapping, respectively, p<0.01). The number of hand clapping performed during the 8s-SHC and the HR values decrease significantly with the increase of body weight, body height and the BMI. Conclusions: An increase in the body size of young women and men has a significant negative effect on their speed abilities measured in the 8s-SHC test

Socioeconomics Influences on the Water Competencies of Young Adult Polish Males

Despite the popularity of aquatic recreation and its well-promoted prophylactic and therapeutic values, not a lot is known about how socio-cultural background influences the acquisition of water competency. The aim of this study was to assess the influence of socio-economic and environmental factors on the swimming and rescue skills of male university students (n = 521) aged 19-20 years residing in the Region of Warmia and Mazury, Poland
