The aim of this paper was to evaluate the scope of influence a modified circuit training of endurance and strength character, carried out in line with an original programme, on the selected physiological parameters. 30 volunteers who train in fitness clubs in Kraków on an everyday basis were selected by means of purposeful selection to participate in the research. This group was divided into two subgroups. One of them used an experimental programme of circuit training, the other took part in the same training programmes they had used so far. After six weeks the two groups were subjected to research. Heart rate and blood lactate levels were measured. Heart rate monitors were used to measure heart rate. Research results show that the proposed training programme is carried out at a high intensity level, which is indicated by the recorded heart rate and blood lactate levels. The research programme carried out with the use of the circuit training positively influences fundamental physiological parameters; average and maximal heart rate frequency were lowered, energy expenditure in the course of the training was lowered; blood lactate levels after the training were reduced as well and post-exercise restitution was increased. The proposed form of training can be an example of physical activity of significant health-oriented advantages.

Praca przedstawia wpływ krótkotrwałych drgań ogólnych o częstotliwości 3.5 Hz na wybrane parametry fizjologiczne sportowców. W badaniu zastosowano platformę wibracyjną generującą drgania harmoniczne o częstotliwości biegu człowieka-3.5 Hz i wzrastającej amplitudzie od 4 do 5,5 mm. W pracy założono, że stanie na platformie w pozycji swobodnej bez wykonywania żadnych dodatkowych ćwiczeń stanowi dla organizmu człowieka trening fizyczny oraz że platforma wibracyjna jest urządzeniem, które odtwarza bodźce mechaniczne występujące w czasie biegu lub szybkiego marszu.

Proper planning of the training process based on individual LT and AT metabolic thresholds is essential to improve athletic performance. Development of endurance in soccer players is mainly based on continuous runs and variable-intensity runs, supplemented with strength conditioning and sport-specific training. The aim of the study was to analyse selected parameters of physical capacity of soccer players after 8-week variable-intensity running training and circuit training. The experiment was carried out in a group of 34 soccer players aged 21 to 26 years. The athletes were divided into two groups: 17 people in the experimental group and 17 people in the control group. The experimental group was involved in 30-minute tempo runs two times a week for 8 weeks with variable intensity at AT. In the same period, the control group performed two 60-minute continuous runs at the intensity of 70-75%HRmax. The determination of metabolic thresholds used two indirect tests: the multistage shuttle run test (beep test) and maximal lactate steady state test (MLSS) with author's own modification. In order to evaluate maximal heart rate (HRmax), the research procedure was started from the beep test (distance: 20 m). The speed at the first level was 8.5 km/h and increased with each level by 0.5 km/h. Training of the experimental group where variable exercise intensity was used caused a statistically significant increase in HRmax (by 1.9%) and blood lactate levels at the AT (by 20.5%). The training in the experimental group led to the statistically significant (p < 0.05) increase in the parameters of the following variables: HRmax (by 1.9%); lactate level (by 7.85); HR at the AT (by 1,9%); lactate level at the AT (by 20.5%). The assumptions of the experimental training did not cause statistically significant changes in pretest vs. posttest HRmax and blood lactate levels for the LT. Endurance training with high intensity is more effective in soccer players compared to training with moderate intensity. Development of special endurance in soccer should also assume the intensity and method of working similar to the method used during sport competition.

A pot experiment was conducted to examine whether the morphological and physiological characteristics of some halophytes may be affected by salt stress. For this purpose, a factorial experiment based on randomized complete block design was carried out with three replications. The treatments were some halophytes (Salicornia europaea, Atriplex leucoclada, and Kochia scoparia) and salinity stress levels [Electrical conductivity 0 (Hoagland’s solution), Hoagland’s solution consisting of 100, 200, 300 and 500 mM NaCl]. Among the halophytes tested, Salicornia europaea had significantly higher shoot and root of dry matters compared to the other halophytes in all salt treatments. Salinity stress resulted in an increase in photosynthetic pigments up to 200 mM and thereafter, it decreased in all of the studied plants. Photosynthetic pigments, ranked in a descending order, were high in Kochia scoparia, Salicornia europaea, and Atriplex leucoclada. In addition, salinity stress led to an enhancement in malondialdehyde (MDA) and H2O2. The tolerance of Salicornia europaea under high salinity stress was associated with low MDA and H2O2 contents as well as high contents of photosynthetic pigments. The shoot and root Na+ increased considerably by augmenting the salinity levels in all halophytic plants; however, there was a significant difference among halophytes at higher salinity levels. The shoot K+ decreased by increasing the salinity levels, but K+ partitioning pattern varied among the halophytes. Under saline conditions, the shoot and root Na+/K+ ratio of all halophytes grew. The highest and the lowest of Na+ were observed in Salicornia europaea and Kochia scoparia, respectively. Thus, the Na+/K+ ratio could be considered as an indicator of salt evaluation. Nitrogen, protein content, dry matter digestibility (DMD), and metabolizable energy (ME) were high in Salicornia europaea plants in comparison to other plants at 200–500 mM salinity levels; in contrast, acid detergent fiber (ADF) and netural detergent fiber (NDF) were low. According to the results of this study, the tolerance of halophytes towards NaCl is possibly due to the differences in damage from reactive oxygen species (ROS), especially H2O2, and toxicity to metabolism Na+.

Drgania mechaniczne, szczególnie niskoczęstotliwościowe, są charakterystyczne dla pracy maszyn roboczych. W zakresie od 3 Hz do 25 Hz mieszczą się częstotliwości rezonansowe większości głównych narządów człowieka, a więc pracę operatorów tych maszyn określić można jako uciążliwą. Dodatkowo praca przy zmiennych obciążeniach i w różnorodnych warunkach zewnętrznych wymaga nieustannej uwagi operatora i częstych jego interwencji. W wielu przypadkach skutkiem działania w takich warunkach jest niewydolność fizyczna operatora, prowadząca do przejściowych bądź trwałych uszczerbków na zdrowiu. W celu ustalenia m.in., czy działanie wibracji zarówno ogólnych, jak i miejscowych powoduje zmiany fizjologiczne u operatorów maszyn roboczych, przeprowadzono eksperyment w warunkach laboratoryjnych z udziałem 30 osób. Z analizy uzyskanych rezultatów wynika, że łączne oddziaływanie wibracji ogólnych i miejscowych niskiej częstotliwości wpływa na zmianę parametrów fizjologicznych osób badanych (skurczowe i rozkurczowe ciśnienie tętnicze krwi, tętno oraz temperaturę ciała).

The Moroccan olive oil industries generate a substantial amount of olive mill wastewater (OMW), causing a significant environmental issue. Consequently, its valorization represents a sustainable agroecological solution to the environmental problems caused by this uncontrolled discharge. In this context, the use of OMW as an organic biofertilizer in agriculture has been suggested as an alternative to restore soil fertility and improve agricultural production. To comprehensively understand its impact, the conducted study focused on the local cultivar Vicia faba L., investigating the consequences of daily applications of OMW at varying doses (5%, 10%, 20%, 30%). In the experimental design, NaCl solutions, mimicking the electrical conductivity of OMW, were used to pinpoint the potential phytotoxic agents within the wastewater. The results revealed that a high dose of OMW had significant effects on morphological, physiological, and biochemical parameters. Additionally, phytotoxicity depended on both OMW concentration and the growth stage of Vicia faba L., causing growth delays, germination inhibition, as well as the accumulation of proline and soluble sugars. These findings underscore the complexity of using OMW in agriculture and highlight the critical importance of precise control over application rates for the success of this approach. While reusing OMW presents a viable and practical solution, a nuanced understanding of its impact on specific crops and a meticulous approach to dosage management are imperative to realize its potential benefits and mitigate any potential risks to crop productivity.

The aim of the study was to determine the effect of ozone fumigation and spraying with microorganisms, i.e. yeast, on selected physiological parameters, and the extent of disease infection of tomato plants. Tomato plants were grown in the ground under covers. Throughout the 2021 and 2022 growing season, the plants were exposed to variable factors, i.e. fumigation with gaseous ozone at a dose of 2 ppm for 1 minute and spraying with yeast. After ozonation and spraying with yeast, physiological measurements were made on tomato plants, such as: selected parameters of chlorophyll fluorescence (maximum quantum yield of PSII photochemistry, maximum quantum yield of primary photochemistry) and gas exchange parameters (transpiration rate, stomatal conductivity and intercellular CO2 concentration). In addition, the content of chlorophyll using the SPAD method as well as plant infection by diseases was determined. Compared to the control sample, ozonation resulted in a slight decrease in the physiological parameters of tomato plants. In addition, no visible leaf damage was observed after the ozone gas fumigation process. However, the use of microorganisms did not significantly change the examined physiological parameters. Both after the application of gaseous ozone and microorganisms, a significant impact of the tested variable factors was found on reducing the infection of tomato plants by diseases such as: tomato late blight, tomato alternariosis, gray mold, bacterial canker of tomato and bacterial spot of tomato.

Celem pracy było określenie wpływu ozonowania oraz opryskiwania mikroorganizmami, tj. drożdżami na wybrane parametry fizjologiczne oraz stopień porażenia roślin pomidora przez choroby. Rośliny pomidora uprawiano w gruncie pod osłonami. Przez cały sezon wegetacyjny 2021 i 2022 rośliny poddawano działaniu zmiennych czynników, tj. fumigacja gazowym ozonem w dawce 2 ppm przez 1 minutę oraz oprysk drożdżami. Po ozonowaniu i oprysku drożdżami, dokonano pomiarów fizjologicznych pomidorów, takich jak: wybrane parametry fluorescencji chlorofilu (maksymalna wydajność kwantowa fotochemii PSII, maksymalna wydajność kwantowa fotochemii pierwotnej) oraz parametry wymiany gazowej (szybkość transpiracji, przewodnictwo aparatów szparkowych oraz międzykomórkowa koncentracja CO2). Ponadto, określono zawartość chlorofilu za pomocą metody SPAD jak również stopień porażenia chorobami. W porównaniu z próbką kontrolną ozonowanie spowodowało nieznaczne obniżenie parametrów fizjologicznych roślin pomidora. Ponadto nie zaobserwowano widocznych uszkodzeń liści po procesie fumigacji gazem ozonowym. Dodatkowo zastosowanie mikroorganizmów nie zmieniło istotnie badanych parametrów fizjologicznych. Zarówno po zastosowaniu gazowego ozonu, jak i mikroorganizmów stwierdzono istotny wpływ badanych czynników zmiennych na ograniczenie porażenia roślin pomidora chorobami takimi jak: zaraza ziemniaka, alternarioza pomidora, szara pleśń, bakteryjny rak pomidora i bakteryjna plamistość pomidora.

Salvinia natans L. is a known bioaccumulator of metal ions from the aquatic environment. Exposure of plants to prolonged impact of toxins along with a large dose of the metal affects the physiological condition of the plants. The changes occurring in the plants in the phytoremediation process in contaminated medium culture of 5, 10, 15 and 20 mg Cu/dm3 show two basic physiological parameters: the assimilation pigment content (chlorophyll a and b) responsible for the production of energy in the process of photosynthesis, and the total protein level as the main constituent of the plant. Conducted studies confirmed a negative effect of high concentrations of copper(II) on Salvinia natans L. plants which in these conditions are capable to bioaccumulate metal from each contaminated culture medium.
