“…A previous study demonstrated that oral polyphenol supplementation is a critical sports nutrition strategy to facilitate mitochondrial biosynthesis for athletes to delay the onset of exercise fatigue and to enhance performance [13,14]. Resveratrol (RES), as a nutritional supplement, is a natural polyphenol compound accompanied by functions of increasing antioxidant activity [15], anti-inflammation [16], anti-aging [17] and diabetes prevention [18].…”

The present study aimed to investigate the effect of oral resveratrol supplementation on the key molecular gene expressions involved in mitochondria biogenesis and glycogen resynthesis in human skeletal muscle. Nine young male athletes participated in the single-blind and crossover designed study. All subjects completed a 4-day resveratrol and placebo supplement in a randomized order while performing a single bout of cycling exercise. Immediately after the exercise challenge, the subjects consumed a carbohydrate (CHO) meal (2 g CHO/Kg body mass) with either resveratrol or placebo capsules. Biopsied muscle samples, blood samples and expired gas samples were obtained at 0 h and 3 h after exercise. The muscle samples were measured for gene transcription factor expression by real-time PCR for glucose uptake and mitochondria biogenesis. Plasma glucose, insulin, glycerol, non-esterified fatty acid concentrations and respiratory exchange ratio were analyzed during post-exercise recovery periods. The results showed that the muscle glycogen concentrations were higher at 3 h than at 0 h; however, there were no difference between resveratrol trial and placebo trial. There were no significantly different concentrations in plasma parameters between the two trials. Similarly, no measured gene expressions were significant between the two trials. The evidence concluded that the 4-day oral resveratrol supplementation did not improve post-exercise muscle glycogen resynthesis and related glucose uptake and mitochondrial biosynthesis gene expression in men.

“…Its dynamics allows predicting the growth of sportsmanship. In the work of Gaamouri et al [22] control of body weight and somatotype components was used to assess the effectiveness of the use of dietary supplements. A similar approach was used by Martinelli et al [23] to assess the status of taekwondo athletes in the pre-competition period and during post-competition recovery.…”

Background and Study Aim. The aim of the article is a comparative analysis of the morphofunctional characteristics of athletes of various types of martial arts as factors of success. Material and Methods. The study participated students involved in martial arts (n = 29; age - 17.53 ± 0.15 years). The first group (group 1 - wrestlers) included judo, sambo, wrestling athletes (n = 12, age - 18.58 ± 0.38 years). The second group (group 2 - athletes of percussion martial arts) included athletes of karate, taekwondo (GTF), taekwondo (WTF), (n = 17; age - 18.12 ± 0.26 years). Determined 46 morphofunctional indicators: length and body weight; chest circumference in a pause, on inhalation and exhalation; length and circumference of the segments of the upper and lower extremities; wrist dynamometry. A goniometric study of the range of motion in the joints of the upper extremities was carried out. The dynamic grip strength was determined by the maximum frequency of hand squeezing in 10 seconds. To characterize the data, the median was determined - the first (25%) and third (75%) quartiles. Differences between groups were assessed using nonparametric criteria of Wilkinson-Mann-Whitney (U) and Rosenbaum (Q). Results. Athletes in group 1 had a greater interquartile range compared to athletes in group 1 in the following indicators: body weight; chest circumference in a pause, on inhalation and exhalation; hand dynamometry of the right and left hands; maximum frequency of the hand grip in the impulse mode with the left hand; shoulder width; circumference of the shoulder, forearm, thigh and lower leg. Athletes of percussion martial arts were characterized by large values of the shin length. The amplitude of abduction and adduction in the right wrist joint, the amplitude of abduction in the left wrist joint was greater in the wrestlers. Athletes of percussion martial arts had a large amount of extension of the left wrist joint, flexion of the right elbow joint, extension and abduction of the right shoulder joint. Conclusions. Analysis of morphofunctional indicators of athletes of various types of martial arts confirmed the specific effect of the sport on the body of athletes. The features that are the factors of success are highlighted. For wrestlers, these include hand strength in various modes. It allows to implement quickly and efficiently grip. This is the basis for a successful wrestling technique. Sufficient development of the muscles of the limbs ensures the execution of throws in wrestling. The lengthened calf size contributes to a more effective kick in martial arts. Goniometric features of movements reflect the possibility of high-quality gripping, striking or blocking. The used morphofunctional indicators can be applied to predict the success of athletes in various types of martial arts.

Introduction. A coach compiles and determines a training program based on the physical fitness profile of the athlete. Central Sulawesi taekwondo and karate athletes have been undergoing independent training since mid-2020. Objective of the study. This study aims to investigate the comparison in physical fitness of elite athletes in taekwondo and karate Research methods. This study uses a causal-comparative method, where the researcher seeks to determine the cause or effect of the differences that occur between groups. The sample of this research is 20 elite athletes. Evaluation of physical abilities or physical fitness is an instrument used to measure the physical fitness of taekwondo and karate athletes. An independent sample t-test was used for comparison of independent samples. Research result and Conclusion. The results and conclusions of the study indicate that descriptively the speed, endurance of abdominal muscle strength, and endurance of thigh muscle strength, agility, flexibility, leg reaction speed, and cardiovascular endurance of taekwondo athletes are higher than karate athletes, while for leg muscle strength and breathing karate athletes are higher than taekwondo athletes. Sig value. (2 tailed) or p-value <0.05, it can be concluded that there is a significant difference in the variable components of physical fitness, abdominal muscle strength, agility, flexibility in leg reaction speed, and cardiovascular endurance between taekwondo athletes and karate athletes. Whereas in the variable components of physical fitness, speed, endurance, thigh muscle strength, and leg and respiratory muscle strength, there were no significant differences between taekwondo athletes and karate.
