Introduction: New form of suspension training (TRX) has been introduced which has the ability to develop physical fitness factors. The aim of this study was to compare the effects of eight weeks of resistance training by traditional and TRX methods on physical fitness f actors and extremities perimeter of non -athlete underweight girls. Material and methods: Thirty non -athlete underweight female students qualified with an average age of 23±1.64 years, weight of 43.53±0.28 kg, height of 162.66±6.6 cm and BMI of 16.31±0.2 kg /m 2 were selected and randomly assigned into three groups of 10 subjects (traditional, TRX and control) . Participants performed training of 3 sessions per week for eight weeks. Before and after the period of training, physical fitness variables including m uscular strength and endurance, flexibility, thigh and arm circumferences were measured. Results: The results showed that both forms of training had a significant effect on muscular strength and endurance. There was no significant difference in flexibilit y and thigh and arm circumferences. Conclusion: It can be concluded, that the traditional and TRX training have created almost same improvements in physical fitness factors, so TRX training can be considered an efficient choice to do alongside traditional training or as its alternative in order to earn desired training achievements. It is noteworthy that when training goal is to enhance muscular strength and endurance especially in upper -body, TRX training appears to be accompanied by greater gains compared to traditional resistance training.

The purpose of this study was to compare the effects of an 8-week training period of strength training alone (GR), or combined strength and endurance training (GCOM), followed by 12-weeks of de-training (DT) on body composition, power strength and VO2max adaptations in a schooled group of adolescent girls. Methods: Sixty-seven healthy girls recruited from a Portuguese public high school (age: 13.5±1.03 years, from 7th and 9th grade) were divided into three experimental groups to train twice a week for 8 wks: GR (n=21), GCOM (n=25) and a control group (GC: n=21; no training program). Anthropometric parameters variables as well as performance variables (strength and aerobic fitness) were assessed. Results: No significant training-induced differences were observed in 1kg and 3kg medicine ball throw gains (2.7 to 10.8%) between GR and GCOM groups, whereas no significant changes were observed after a DT period in any of the experimental groups. Significant training-induced gains in CMVJ (8 to 12%) and CMSLJ (0.8 to 5.4%) were observed in the experimental groups. Time of 20m significantly decreased (GR: -11.5% and GCOM: -10%) after both treatment periods, whereas only the GR group kept the running speed after a DT period of 12 weeks. After training VO2max increased only slightly for GCOM (4.0%). No significant changes were observed after the DT period in all groups, except to GCOM in CMVJ and CMSLJ. Conclusion: Performing simultaneous strength and endurance training in the same workout does not appear to negatively influence power strength and aerobic fitness development in adolescent girls. Indeed, concurrent strength and endurance training seems to be an effective, well-rounded exercise program that can be prescribed as a means to improve initial or general strength in healthy school girls. De-training period was not sufficient to reduce the overall training effects.

Researchers’ interest in men’s body image disorders has been growing continually. Within the studies, a new nosological unit has been put forward, i.e. muscle dysmorphia, and diagnostic criteria have been presented. The world literature indicates that those with a disturbed image of one’s body developmental disorders more frequently, as compared to the general population. This study was aimed at assessment of the incidence of mental disorders in the men, who practise an intense weight training. The study involved two groups of volunteers: a group of forty men practising an intense weight training (examined group) and a group of thirty five men, who did not practise such training (control group). The study was carried out using the MINI and MASS questionnaires. The examined group showed a higher incidence of their muscle appearance dissatisfaction. One person met all the criteria of the muscle dysmorphia according to Pope et al. This group more often exhibited affective disorders: bipolar affective disorders (BAD) and mania or hypomania syndromes of unknown aetiology (22.5%, as compared to 2.86% in the control group); the incidence of personality antisocial disorders was on the borderline of statistical significance (p=0.0569). A correlation was found between the severity of muscle dysmorphia traits measured by MASS scores and incidence of affective disorders, anxiety, and personality antisocial disorders. The Muscle Appearance Satisfaction Scale (MASS) may appear to be a useful diagnostic instrument applicable in sportsmen, however this calls for further studies with participation of larger groups.

Coraz większe zainteresowanie badaczy wzbudzają zagadnienia związane z zaburzeniami obrazu własnego ciała u mężczyzn. W toku prowadzonych badań zaproponowano nową jednostkę chorobową – dysmorfię mięśniową – i przedstawiono kryteria diagnostyczne. Z literatury światowej wynika, że u osób z zaburzonym obrazem własnego ciała częściej niż w populacji ogólnej występują inne zaburzenia psychiczne. Celem niniejszej pracy była ocena częstości występowania zaburzeń psychicznych u mężczyzn intensywnie ćwiczących. Badaniu poddano dwie grupy ochotników: czterdziestoosobową grupę mężczyzn uprawiających intensywny trening siłowy (grupa badana) oraz trzydziestopięcioosobową grupę mężczyzn niećwiczących (grupa kontrolna). Badanie przeprowadzono za pomocą kwestionariuszy MINI i MASS. W grupie badanej stwierdzono większą częstość występowania niezadowolenia z wyglądu mięśni. Jedna osoba spełniała wszystkie kryteria dysmorfii mięśniowej wg Pope'a i współpracowników. W grupie tej częściej występowały zaburzenia afektywne: CHAD i zespoły manii bądź hipomanii o niewyjaśnionej etiologii (22,5% wobec 2,86% w grupie kontrolnej), na granicy istotności statystycznej (p=0,0569) większa była częstość występowania zaburzeń antyspołecznych osobowości. Stwierdzono istnienie korelacji pomiędzy nasileniem cech dysmorfii mięśniowej mierzonym punktacją w MASS a częstością występowania zaburzeń afektywnych, lękowych i zaburzeń antyspołecznych osobowości. Skala zadowolenia z wyglądu mięśni (MASS) może okazać się przydatnym narzędziem diagnostycznym możliwym do zastosowania wśród sportowców, jednak konieczne są dalsze badania z udziałem liczniejszych grup.
