The presented film shows the course of strength testing of the framework of a 05 Standard cabin, manufactured by FUM "Spomasz", Sokółka, Poland. The objective of this testing was to establish whether the cabin framework can be considered safe for the MF-255 tractor. Strength testing of the framework of a 05 Standard cabin, was recorded using a Panasonic type NV-M5 camera. This camera is not only capable of recording, but also has the capacity for fast forwarding and rewinding the picture on screen, freeze frame function, and the so called fast shutter, permitting better viewing of fast changing images. The Panasonic VCR type NV-N70EG allows viewing of images recorded with fast shutters with maximum clarity and focus. The Department plans to purchase an IBM AT personal computer with peripherals designed to enter video images into the computer’s memory for further processing. This technique will not only allow more precise analysis of cabin elastic strain in strength testing, but will also facilitate studies of the functionality of agricultural tractors and machinery operation, assessment of the operator’s visibility, etc.
Background: The aim of the study was to determine the preferences in the use of nutritional supplements and the correctness of their selection in training among recreational athletes attending classes at the gym. Material/Methods: A group 169 of recreational athletes was surveyed in "AWF Warszawa" and "Warszawianka" gyms; they were 26.6 years old ±6.48 yrs and had 4 years ±4.57 of training experience. The diagnostic survey method was used, with questionnaires developed by the authors of this study. Results: A significantly smaller proportion of respondents declared the use of supplements. The supplementation declared most often involved the use of chain amino acids (BCAA), high-protein supplements and creatine. A small proportion of the respondents declared the use of carbohydrate supplements. Respondents declared taking more than one supplement at the same time. Most often the protein supplements were combined with BCAA, creatine, vitamins and minerals. A lack of knowledge manifested itself in many declarations such as taking supplements with similar composition at the same time, the consumption of excessive doses of certain substances, not knowing rules for maintaining the correct proportions of the basic ingredients of a diet or a need for supplementation with certain substances, depending on the type of exercise. Athletes wanted to achieve one to two training goals in their classes, but the selection of supplements to help achieve these goals was wrong. There was no significant preference given to the type of exercise (aerobic, strength), indicating that many types of exercise were to be implemented in parallel during one training session. Conclusions: The use of supplements among recreational athletes is not as widespread as is commonly thought. The declared supplementation had a standard structure. The number of substances used at the same time is lower than in athletes in high sports classes. A widespread lack of knowledge of the training process can eliminate the effects of supplementation. It can also cause harm to health and nutritional deficiencies. The implementation of properly selected training goals may be impossible when supplementation is chosen poorly. Although it is permissible to perform different types of exercise in a training session, the exercise choices made by recreational athletes often seem accidental.
Background: The aim of the study was to investigate the effectiveness of kettlebell exercises in the aspect of shaping the special efficiency characteristics required by American football players. Material/Methods: The kettlebells training group (n = 12) and the American football group (n = 12), who used training typical of their discipline, were subjected to a fitness test in US football, consisting of a 40-yard run speed test, an agility test in two shuttle runs, a jumping test in Counter Movement Jump (CMJ), and a power and strength endurance tests. Results: In tests of speed, agility, jumping and power, there were no significant differences between footballers and kettlebell exercisers, while strength endurance testing (benchpress with 100 kg) and one special agility test (two shuttle runs) showed that training with kettlebells develops these qualities of physical fitness significantly worse than standard football practice (p < 0.05). Conclusions: Kettlebell training can be beneficial for shaping most characteristics of the special efficiency needed in American football but it is not able to completely replace the traditional football strength training program, based on exercises with barbells.
Background: The aim of the study was to determine the individual tactical and technical profile of a leading Polish judoka from the heaviest weight category and the characteristic of his body composition in comparison to the world’s elite in this category. Material/Methods: 92 fights carried out by the Polish athlete during national and international tournaments constituted material for the analysis of his technical and tactical profile. 12 judo competitors (1 Polish athlete and 11 competitors from 10 other countries) of the heaviest weight category at the top level of sports championship were subject to anthropometric measurements including 19 features. To evaluate the somatic types, Sheldon’s method with Heath-Carter’s modification was applied. Results: In his duels, the subject most efficiency performed throws from the ashi waza group, out of which he scored the most points and victories before the regular time using osoto gari. The throws from the te waza group proved to be the second most effective with the dominant throw being seoi nage executed from the knees. The subject’s body height (199.0 cm) was higher than the mean for the control group (188.9 ±8.3 cm), and his body weight (113.0 kg) was lower than the mean of the world’s leading athletes (119.4 ±18.2 kg). Mesomorphy dominated in the somatic type of the Polish athlete; however, in the control group its value was higher (6.0–8.3–1.5). Conclusions: To raise the efficiency of fights, the subject should increase the muscle mass and use his natural physical predispositions on the basis of the prospective analysis of its impact on the tactical and technical profile.
