ANAEROBIC POWER IN SPORTS

The aim of the present study is to determine the anaerobic power of men of similar age representing different sports disciplines. Professional athletes representing the following sports participated in the study: soccer (n=15, PS), martial arts (n=12, MA), weightlifting (n=15, WL), powerlifting (n=15, PL), middle- and long distance running (n=12, DR), race walking (n=14, RW), and recreational soccer (n=15, RS). After recording personal and somatic data, the subjects performed a 3-minute warm-up followed immediately by a 30 seconds cycloergometric Wingate test. The following variables of anaerobic power were calculated: total external work (TEW-KJ/30s), maximal power (Pmax-W/kg), mean power (Pmean-W/kg), fatigue index (FI-%). It was shown that the examined groups differed in body weight (F=13.560, p<0.001), body height (F=3.342, p<0.01) and BMI (F=28.868, p<0.01). There were also significant differences in the TEW range (F=5.764, p<0.001), Pmax (F=2.807, p=0.013) and FI=4.942, p<0.001) and no intergroup difference in the Pmean range. In conclusion, it should be pointed out that various types of sports training develop in the various degree different components of anaerobic power, however they develop similarly its average value.

BACK PAIN CHARACTERISTICS IN PHYSICAL AND OFFICE WORKERS

The aim of our study was to characterize back pain according to the occupation comprising physical and office work. Accordingly questionnaires from 100 physical workers (PW) and 100 office workers (OW) were collected. This dedicated questionnaire included 19 questions, of which 7 concerned demographic, work and stature features and 12 concerned back pain. Collected data showed that lower back pain was more common in PW but cervical pain in OW (p<0.001). Most common aetiology of back pain was spinal osteoarthritis, sciatica and scoliosis but of different spread in two groups (p<0.001). The history of back pain was most often above 5 years and there were significant differences in frequency, intensity and pain handling methods between groups (p<0.005). Back pain prophylaxis was well acknowledged in both groups (85 % in OW, 91 % in PW). Regular physical activity was considered the main prophylaxis method (67 % in PW, 89 % in OW) and similarly incorporated in both groups (p=0.691) however OW more often performed physical exercises (p<0.001). Physical therapy was used in both groups (PW 100 %, OW 92 %, p=0.004) but with variable efficacy according to responders. To conclude there were multiple differences between both groups in terms of the pain characteristic but with similar awareness and incorporated prophylaxis.

The state of physical activity and its perception in oncological patients

Background: Malignant neoplasms constitute significant danger to humans on a global scale. however, the effects of oncological therapies continue to be unsatisfactory. in order to improve the treatment results, new or additional therapeutic and preventative methods are being researched. One of such methods is physical activity, carefully chosen and executed in safe conditions. its values include: low cost, availability, safety and lack of side effects.

Somatyczna determinacja płciowa w nadwadze i otyłości

Wstęp: Somatyczne wielkości, takie jak masa (Mc) i wysokość ciała (Wc), są używane do wyliczania wskaźników wagowo-wzrostowych i stanowią pomoc w diagnozowaniu nadwagi i otyłości. Cel pracy: Celem pracy jest ocena nadwagi i otyłości kobiet i mężczyzn w świetle prostych wskaźników somatycznych. Materiał i metody: W prezentowanej pracy porównano wskaźniki somatyczne 179 kobiet i 181 mężczyzn z nadwagą i otyłością. Do oceny somatycznej badanych użyto: Mc, Wc oraz wskaźników wagowo-wzrostowych: Queteleta, BMI, Rohrera i smukłości. Wyniki: W badanych grupach kobiety i mężczyźni byli w zbliżonym wieku, grupy te różniły się istotnie omawianymi wskaźnikami somatycznymi. Porównania podgrup kobiet i mężczyzn o podobnej wielkości BMI wykazały, że są oni w podobnym wieku i różnią się w zakresie Mc, Wc oraz wskaźników: Queteleta, Rohrera i smukłości. Natomiast między podgrupami kobiet, jak i między podgrupami mężczyzn, występowały istotne różnice wiekowe, Mc oraz wskaźników: BMI, Queteleta, Rohrera i smukłości. Wnioski: Powyższe dane wskazują, że pomimo braku różnic wieku między badanymi kobietami i mężczyznami z podobnym lub różnym BMI istnieje wyraźna somatyczna determinacja płciowa, natomiast w obrębie tej samej płci, różniącej się wskaźnikiem BMI, wiek badanych jest czynnikiem determinacji somatycznej. Wykazano też, że badane wskaźniki somatyczne mają różną moc predykcyjną w zakresie oceny nadwagi i stopnia otyłości badanych kobiet i mężczyzn.

The Anaerobic Power of Women who have Undergone Physical Training

Introduction. Anaerobic power is an important factor determining the physical performance in various kinds of sports. Therefore, the aim of this paper is to present women’s anaerobic power in soccer players (SP), table tennis players (TT) and weightlifters (WL). Methods. This study involved 3 groups of professional athletes women: 15 SP, 12 TT and 12 WL, which are of a similar age and sports’ level. Anaerobic power in all athletes was recorded during 30-second Wingate test, with resistance set at 0,075 kp x kg (–1). Results. Relatively expressed total external work (TW), maximal power output (Pmax) and the fatigue index (FI) of tested athletes were similar. Mean power (Pmean) was different among the treatment groups (F=12,445; p<0,001), while in TT group these values were significantly lower than in SP and in WL athletes. Somatic variables in 3 groups of tested athletes have not changed. Conclusions. Type of practiced sport has an impact on the size of anaerobic power. Several years of sports training in table tennis has not changed the anaerobic potential of surveyed women while specific training in soccer and weightlifting increased only Pmean.
