Opis:
The aim of the presented work is to describe the different trends in race walkers training and the biological adaptation of the body to the applied stresses, and to characterize the other phenomena accompanying this sport. The article is equally concerned with the scientific premises as well as the practical training indications. For a deeper characterization of the discussed problems, the biological considerations that underpin the selection of people to practice race walking are broadly described. It has been shown that diagnostic test that reveal the overall exercise potential of the body are useful tools in this area, and its specific development is related to the use of balanced training in which the most difficult part is to strive for optimal mastery of the sport walking technique. It was also suggested, that physiological, biomechanical and dietary determinants, which are assessed in scientific laboratories would be helpful for trainers and race walkers in achieving championship in race walking. The general nature of race walking was supplemented with a description of the social phenomena associated with this sport competition. The conclusions drawn in this article indicate the importance of mastering the technique of walking, the predisposition to practicing this sport, the importance of a coach in achieving high sports results, and the opportunity of health benefits mainly through the practice of recreational walking.

ventilatory threshhold
Opis:
Ventilatory threshold is one of the ways to measure cardiovasculatory fitness of the body. Therefore, in the present study it was decided to demonstrate which physiological parameters most accurately express the second ventilatory threshold (VAT2) depending on the cardiovasculatory fitness of different groups of athletes and untrained men. The study involved the following athletes: race walkers (n=14), weightlifters (n=16), powerlifters (n=16), runners (n=14), professional soccer players (n=13), amateur soccer players (n=16), martial arts (n=12), and untrained men (n=15). Subjects’ VAT2 and maximal load (ML) were recorded and at these levels were determined the value of achievable maximal power (P), oxygen uptake (VO2), heart rate (HR), the ratio for oxygen uptake and heart rate (VO2/HR) and the rate-pressure produkt (RPP). It was shown that subjects were of similar age but different body mass (BM) and BMI. There were also differences between athlete groups at VAT2 and ML in relation to: P, VO2, VO2/HR (p<0.001) and RPP only at VAT2 (p<0.023). Reached HR values at VAT2 as well as at ML have not differed between the groups. There were also intergroup differences at VAT2 in terms of relative values: %VO2max (p<0.002), %Pmax(p<0.016), %VO2max/%HRmax (p<0.03). Relatively expressed %HRmax and %RPPmax reached at VAT2 did not differ between the two groups. Runners, professional soccer players and race walkers achieved the most favorable indicators of physical performance. It has been demonstrated that VAT2 besides P i %Pmax was best described by VO2, %VO2max and by VO2/HR and %VO2max/%HRmax, as well as by RPP. On the other hand HR and %HRmax, as well as %RPPmax are not useful in this regard. Furthermore it should be recognized that athletes in whose structure of the training occurred running of varying intensity achieved the highest physical fitness.

Opis:
Introduction: Obesity is an unfavorable state of health as a result of which come in the initial adaptation, that could gradually transform into specific disease condition. Objectives: The aim of the study was to assess the degree of middle-aged men adaptation to obesity in terms of somatic changes, exercise capacity and cardiopulmonary fitness. Materials and Methods: The study involved 12 obese middle-aged men (OG) - BMI = 34.32 ± 4.11 kg/m2. The control group (CG) consisted of 12 non-obese middle-aged men- BMI = 23.72 ± 1.83 kg/m2,with similar body height (BH) to OG. After recording somatic and physiological data at rest, participants were subjected to the bicycle ergometer test (BT) gradually increasing intensity. During the BT aerobic power (AP) was recorded and analyzed along with parameters characterizing the efficiency of the circulatory and respiratory systems at anaerobic threshold (AT) and the maximum load (ML). Results: This study has shown that obese men have a higher body mass (BM), a higher content of fat (BF), an increased lean body mass (FFM) and a higher content of water (TBW) than CG (p <0.001). Absolute and relatively expressed in relation to the FFM respondents’ values of AP and VO2 were similar in both groups and after taking under the consideration the body weight, they were significantly lower in OG than in the CG. Furthermore, adverse effects have been observed that emerged on some cardiovascular and respiratory variables at rest in case of OG; these effects did not occur during physical exertion. Conclusions: Beyond negative changes occurring obesity in the first stage led to favorable somatic adaptation that entails an increase of FFM in OG, which gives a positive impact on the capacity of physical work of obese men and produces a beneficial effect on the resulting compensation impairment in the respiratory and circulatory systems of these subjects.
