Background: The main aim of the present study was an attempt to answer the enquiries concerning the influence of physical training on morphological changes (anthropometric indicators), capability of anaerobic work and their interactions with a natural development of youth in pubertal and post-pubertal age.Material/Methods: The technique of parallel groups was used: experimental (handball trained [TR]) and control (not trained [NT]). The research period comprised two consecutive years. Once per year selected somatic parameters, body composition, biological age, and anaerobic parameters were determined by means of 30 s Wingate Anaerobic Test (WAnT).Results: Results have shown the high intensity of boys' biological development in circumpubertal age in response to several years of training handball. A further analysis indicated smaller dispersion of parameters describing the growth and physiological development of the TR group than in NT. The results suggest that handball training caused a significant improvement in morphological and functional indicators. Consequently, capabilities of physical effort increase and a more harmonic development is achieved. Moreover, the results have shown that capabilities of anaerobic work in the TR group have differently depended on the time of progressive development, whereas in the NT group there has been an increase in these capabilities in relation to the age of the examined boys.Conclusions: Several years of handball training did not influence the increase in anaerobic efficiency of pre-pubertal age boys. On the other hand, handball training in pubertal and post-pubertal age boys caused a statistically significant increase in maximum anaerobic power (MPWAnT). A high positive correlation between weight and MPWAnT confirms a relationship between anaerobic power and body growth during puberty.

Wstęp: Jednym z niekorzystnych następstw radykalnej mastektomii jest obrzęk limfatyczny kończyny górnej (OLKG). Mechanizm jego powstawania nie jest do końca wyjaśniony. U części chorych wskazuje się na predyspozycje konstytucjonalnych operowanych. Istniejące parametry somatyczne mogące być przydatnymi w szacowaniu ryzyko rozwoju OLKG rzadko są jednak przedmiotem longitudinalnych pooperacyjnych obserwacji. Cel badań: Celem badań było prześledzenie zmian wybranych parametrów somatycznych u kobiet z OLKG i bez OLKG w trakcie pooperacyjnej obserwacji po amputacji piersi. Materiał i metody: Analizie poddano 45 kobiet, u których wystąpił OLKG po radykalnej mastektomii. W tej grupie chorych jak również w grupie kontrolnej (41 kobiet bez OLKG) dokonano analizy zmian masy ciała oraz wskaźnika BMI, Rohrera, Queteleta i Pigneta-Verwaecka. Parametry te oceniano przed zabiegiem jak równieŜ w okresie 5 – letniej pooperacyjnej obserwacji. Wyniki: Stwierdzono, że przez cały czas trwania kontrolnych badań longitudinalnych średnie wartości masy ciała oraz wskaźnika Rohrera, Queteleta i Pigneta-Verwaecka. Znamienne statystycznie różnicowały grupę kobiet z OLKG od grupy bez obrzęku. Jedynie średnie wartości wskaźnika BMI od 30. miesiąca po zabiegu były porównywalne dla obu grup kobiet. Wniosek: Wykazano, że pomimo wydłużania okresu obserwacji, badane parametry antropometryczne (z wyjątkiem BMI) nie tracą swego przedoperacyjnego znaczenia czynników różnicujących w sposób istotny statystycznie grupy kobiet z OLKG od kobiet bez tego powikłania.

Introduction: Lymphoedema of the upper limb (ULL) is one of the most unfavorable sequels of radical mastectomy. Mechanism of its formation is not completely elucidated. In some patients, constitutional predispositions of the operated women are considered responsible for lymphoedema formation. The existing somatic parameters may be useful in determining the risk of ULL development, however they are rarely addressed in longitudinal post-operative observations.Purpose of the study: The aim of the study was to observe changes in selected somatic parameters in women with and without ULL during post-operative follow-up after breast amputation.Material and method: The analysis comprised 45women, in whom ULL occurred after radical mastectomy. In this group of patients as well as in the control group (41 women without ULL), changes in body weight, and in the following indices: Rohrer, Quetelet, Pignet-Verweack, and BMI were analysed. These parameters were evaluated before the intervention and during a 5-year post-operative follow-up.Results: We observed that during the whole period of the control longitudinal study, mean values of body weight and of Rohrer, Quetelet and Pignet-Verweack indices statistically significantly differentiated the group of women with ULL from that without ULL. Only were mean BMI values comparable for both groups of women beginning with the 30th month after the intervention.Conclusions: It was shown that, despite the prolongation of the follow-up period, the anthropometric parameters (aside from the BMI) did not lose their pre-operative significance as factors significantly differentiating the groups of women with and without ULL.
