Od dawna sport przejawiający się w wielu różnych formach, towarzyszy człowiekowi w codziennym życiu. Dużo dyscyplin sportowych sięga swoimi korzeniami do czasów odległych, kiedy to sprawność fizyczna ...gwarantowała przetrwanie. Obecnie żyjemy w takich czasach, w których nie sposób nie zauważyć sportu, pełniącego tak wiele ważnych ról w społeczeństwie. Sport amatorski jak i wyczynowy staje się częstą formą spędzania wolnego czasu. W dzisiejszych czasach jest on ucieczką od codzienności, stresu, zmęczenia. Niestety nie wszyscy wiedzą i rozumieją jak długa droga jest do sukcesu sportowego, zaangażowania i poświęcenia od sportowców i ich trenerów oraz całego sztabu ludzi odgrywających mniej lub bardziej ważne role w karierze zawodników. Aby realizować ambitne plany, należy wyznaczyć optymalne obciążenia treningowe, pamiętając przede wszystkim o zdrowiu sportowca, ponieważ żaden organizm nie będzie tolerował intensywności, nawet tej umiarkowanej, jeżeli nie będzie odpoczywał i regenerował sił. Trudno sobie wyobrazić profesjonalny trening bez prawidłowego i systematycznego prowadzenia postępowania odnawiającego. Rośnie zapotrzebowanie na specjalistów poszukujących nowych dróg w doskonaleniu sportowców i stosujących prawidłowe metody z zakresu odnowy biologicznej. Celem mojego artykułu jest ukazanie zjawiska oraz czynników temu towarzyszących. Odnowa biologiczna jest oddziaływaniem na organizm różnorodnych środków naturalnych i sztucznych oraz warunków środowiskowych w celu przyśpieszenia fizjologicznych procesów wypoczynkowych. AbstractFor a long time sport manifests itself in many different forms, accompanies man in everyday life. Many sports go back to the distant past, when physical fitness ensured survival. We are now living in times when it is impossible to miss sports that play so many important roles in society. Amateur and professional sports become a common form of leisure. correct methods of wellness. The purpose of my article is to show the phenomenon and factors accompanying it. Biological renewal is the impact on the body of various natural and artificial resources and environmental conditions in order to accelerate physiological resting processes. Nowadays, it is an escape from everyday life, stress, fatigue. Unfortunately, not everyone knows and understands how long the journey is for sports success, commitment and dedication from athletes and their trainers and the entire staff of people playing more or less important roles in the athletes' career. To achieve ambitious plans, the optimal training load should be determined, keeping in mind primarily the athlete's health, since no body will tolerate intensity, even moderate, unless he rests and regenerates. It is difficult to imagine professional training without proper and systematic conduct of renewal. There is a growing demand for professionals looking for new ways to improve athletes and use the correct methods of wellness. The purpose of my article is to show the phenomenon and factors accompanying it. Biological renewal is the impact on the body of various natural and artificial resources and environmental conditions in order to accelerate physiological resting processes.

Background: Watermelon is a rich natural source of l-citrulline. This non-essential amino acid increases exercise performance.
Objective: Evaluate the effect of Fashion watermelon juice enriched in ...l-citrulline (CWJ) (3.45 g per 500 mL) in physical performance and biochemical markers after a half-marathon race.
Design: A randomised, double blind, crossover design where 2 h after drinking 500 mL of CWJ or placebo (PLA, beverage without l-citrulline) amateur male runners performed two half-marathon races. Jump height, heart rate and rating of perceived exertion were evaluated before and after the races. Moreover, muscle soreness and plasma markers of muscle damage and metabolism were evaluated for 72 h after the races.
Results: Muscle soreness perception was significantly lower from 24 to 72 h after the race with CWJ beverage. Immediately after the races, runners under CWJ condition showed plasma lactate and glucose concentrations significantly lower and higher lactate dehydrogenase and l-arginine concentration than runners under PLA. A maintenance of jump heights after the races under CWJ supplementation was found, decreasing significantly with PLA.
Conclusion: A single Fashion watermelon juice enriched in l-citrulline dose diminished muscle soreness perception from 24 to 72 h after the race and maintained lower concentrations of plasma lactate after an exhausting exercise.
Cilj rada je prikazati utjecaj napora na organizam mladog preponskog konja u prvoj natjecateljskoj sezoni. Istraživanja su provedena na šest mladih pastuha (u dobi od četiri i pet godina) treniranih ...i korištenih u preponskom konjičkom sportu, uzgojnog tipa hrvatski sportski konj. Praćeni su treninzi u skakanju prepona u parkuru u dva ponavljanja na početku (svibanj) i na kraju (rujan) natjecateljske sezone. Pripremu i skakanje parkura provela je uvijek ista osoba koja se brine i za kondicijsko stanje konja. Uzimanje uzorka sline (uz pomoć tampona vate) provedeno je u 60. i 15. minuti prije skakanja parkura te neposredno prije skakanja parkura i neposredno nakon skakanja parkura te u 5., 15. i 120. minuti nakon završetka svakoga skakanja parkura (u razdoblju odmora konja). U prvoj natjecateljskoj sezoni mladi preponski konji imali su 23,63% manju koncentraciju kortizola u slini tijekom rujna prije i nakon savladavanja parkura s preponama. Prema utvrđenim vrijednostima koncentracije kortizola u slini mladih preponskih konja može se zaključiti da su konji tijekom rujna identičan parkur savladali s manje stresa i straha. Prva natjecateljska sezona imala je adaptivan učinak na stres i strah mladih konja u preponskom jahanju.
Background: The beneficial properties of tea polyphenols have been extensively studied; however, less attention has been paid to their effects, especially anti-inflammatory effect during exhaustive ...exercise.
Objective: The present study assessed the potential protective effects of tea polyphenols against the fatigue, inflammation and tissue injury caused by an exhaustive exercise bout in rats.
Design: Twenty-four healthy male rats were divided into three groups. Group C was a sedentary control group, Groups E+TP and Group E performed a single exhaustive swimming test; all groups had normal diets, but Group E+TP was supplemented with tea polyphenols. All rats were immediately euthanized after exhaustive exercise, and biochemical and inflammatory parameters, including lactic acid (LA), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-10 (IL-10), lactic dehydrogenase (LDH), and creatine kinase (CK) activity levels, were measured. Reverse transcription (RT) and Real-Time PCR was employed to evaluate the mRNA expression of IL-1β in the liver.
Results: The results showed a decrease in serum LA levels (22%, p < 0.05) in rats that consumed dietary tea polyphenols. Interestingly, dietary tea polyphenols decreased the serum levels of pro-inflammatory factors (TNF-α: 13%, p < 0.05; IL-1β: 10%, p < 0.05; and IL-6: 48%, p < 0.05) and shifted the serum IL-10/TNF-α ratio to a predominantly anti-inflammatory milieu (0.52 ± 0.07 vs. 0.67 ± 0.10, p < 0.01). Furthermore, the polyphenols effectively inhibited the release of tissue damage markers (CK: 24%, p < 0.05 and LDH: 28%, p < 0.05) in the serum and decreased IL-1β mRNA expression in the liver.
Conclusions: This study indicated that tea polyphenols could significantly protect rats from the fatigue, inflammation and tissue damage induced by acute exhaustive exercise.
