Evaluation of Different Equations for Resting Metabolic Rate Prediction in Female Combat Sports Athletes

Only a few studies have produced equations that can estimate resting metabolic rate (RMR) in female athletes, but the accuracy of these equations for combat athletes has not yet been tested. The aim of this study was to evaluate the 12 different equations which are commonly using to determine resting metabolite rate (RMR) in the literature. Twenty-three female combat sport athletes (24.23± 3.39 years; 166.8 ± 5.3 cm; 63.13±6.53 kg; 8.78±3.19 experience years.; 56.40±3.43 VO2 mL/kg/min) were participated this study in voluntarily basis. A cross-validation approach used to compare the accuracy of 12 commonly prediction equations with measured RMR by indirect calorimetry to determine RMR in female combat sports athletes. All the predictive equation was underestimated RMR when compared with the measured RMR (p < 0.05) and the smallest mean difference (92.46 ± 210.38 kcal·d-1) was observed for Altman & Dittmer equation amongst the 12 predictive equations. The Altman & Dittmer equation was accurately predicted 16 out of 30 subjects’ RMR value within the range ±10%. However, based on the Bland–Altman plots, the prediction equations were not accurately nor precisely predicted RMR in the current sample of female combat sport athletes. The results in the present study showed that the Altman & Dittmer equation is most suitable equation to predict RMR amongst 12 equations. Although the Altman & Dittmer equation was resulted with smallest mean difference, it seems that there is need to further research with longitudinal approach to understand the effects of training intensity and body mass changes on RMR in order to develop the formulas already exist used commonly.

Anthropometric characteristic, somatotype, and body composition of Indian Female Combat Sport Athletes: A comparison between Boxers, Judokas, and Wrestlers

Introduction: The aim of this study was:1) to ascertain the anthropometric characteristics of Indian female combat athletes and 2) to determine and compare the sport-specific (boxing, judo, and wrestling) somatotype of Indian female combat athletes. Method: Ninety-nine national level female combat sports athletes (40 Boxers, 25 Judokas, and 34 Wrestlers who regularly compete in national and/or international competitions, took part in the study. Anthropometric measurements were performed for body mass, stature, 7 skinfold sites, 3 girths, and 2 breadths. Somatotypes for all subjects were also calculated. All measurements were statistically analyzed using pairwise comparison analysis and differences between groups were also compared. Results: Significant differences between boxing and judo for the mean value of BMI. Pairwise comparison analysis revealed significant differences in the mesomorphy component between boxing and judo (p = 0.001; 95% CI: -1.83 – -0.40) and between boxing and wrestling (p = 0.001; 95% CI: -1.69 – -0.39); as well as in the ectomorphy component between boxing and judo (p = 0.009; 95% CI: 0.16 – 1.35) and between boxing and wrestling (p = 0.007; 95% CI: 0.17 – 1.25). Conclusion: There are significant differences in anthropometric characteristics when analyzing the somatotype of Indian female combat athletes which could be attributed to the specific demands of each sport. Sport-specific training programmes that consider the anthropometric characteristics and somatotype of female athletes participating in Boxing, Judo and Wrestling should be considered by practitioners and coaches.

The results of the study show that the central body type in athletes in the arts of motion with a percentage of 13% and 40% in combat athletes. Furthermore, the endomorph body type is 13% for motion art athletes and combat athletes with a percentage of 7%. For the endomorph-mesomorph body type as much as movement arts with a percentage of 67% and combat athletes by 47%, while for the Mesomorph, Mesomorph-Ectomorph body type there are no athletes and athletes in the arts of motion and fighting have an ectomorph endomorph body type with a percentage of 7%. The results of the study prove that in athletes in the movement arts category and fighters there are similarities in the body type they have which tend to have endomorph-mesomorph. Conclusions.The conclusion is that the dominant body type in Tarung Derajat athletes shows an endomorph-mesomorph tendency with a percentage value of 67% in the movement arts category and 47% in the fighter category. The data of this study provide the characteristics of fighting somatotypes, which can be used to establish references for systematic research in sports health sciences. The results of this study are expected to influence coaching for training concentration, with more emphasis on somatotype.

Features of psychological state and psycho-physiological indicators of hand-to-hand combat athletes depending on previous sports experience

The article examines the psychophysiological indicators of hand-to-hand combat athletes depending on their previous experience. Athletes who previously engaged in wrestling (n = 14), boxing (n = 10), kickboxing (n = 8), and cyclic speed-power sports (n = 8) took part in the study. During the study, work efficiency, mental stability, and the degree of workability were determined according to the Schulte tables, the time of a simple reaction to light and the time of reaction to a moving object, an indicator of the level of self-assessment of willpower, a tapping test, concentration and switching of attention according to the Bourdon test. To determine the components of sustainability, the "SAN" survey was used according to the Muddy method. Student's t- test was used to determine statistical differences between groups. The relationship between indicators was determined by Pearson's correlation.
 In the work efficiency, the best results were shown by groups II and III. In mental stability, significant differences were observed between groups II and IV. In the time of reaction to light, an advantage was observed in athletes who previously practiced boxing and kickboxing over athletes who were engaged in wrestling and various types of athletics. Statistically significant differences in the time per moving object were found between athletes I and IV, as well as between groups II and IV in favor of group II. According to the shift of attention, significant differences were observed between groups I and II, I and III in favor of groups II and III. The influence of indicators of the components of vitality on psychophysiological indicators has been proven, which will be appropriate to take into account when building a program of psychological training in hand-to-hand combat.

Combat Response Training Tester Based on Intelligent Force-Measuring Sensor and Digital Circuit

In combat sports, the team members take attack and defense as the core of sports, and the technical movements are not periodic and the application process is irregular. During the competition, observe the opponent’s neutral position, judge timely, and react quickly. At the same time, athletes are required not only to master skilled technical movements but also to have rapid and accurate adaptability. In order to improve athletes’ rapid response ability, according to the rapid response training scheme, a combat response training tester based on a force-measuring intelligent sensor and digital circuit is designed to improve the athletes’ response ability. Firstly, a comprehensive test system of combat trainer is designed based on the intelligent force-measuring sensor and MSP430, which can measure the response time, speed, and strength of boxing. Secondly, a wavelet filtering algorithm is used to filter the sensor measurement data. Finally, the striking force and striking time of each action are recorded by sensors and data acquisition devices to reflect the striking effect and reflect the “accurate” objectives of the project characteristics. Based on the noninterference and anti-interference of e-touch piezoelectric film, it can be made into universal force-measuring sensors of different specifications for fight competitions according to needs. After being connected into a module network in parallel, it can be connected with the microcontroller to determine the hit area. In addition, the team reaction training test device has laid a foundation for the scientific evaluation of improving the team members’ reaction ability and attack defense conversion ability. The launch of the comprehensive ability tester for combat athletes introduces the previous fuzzy evaluation of athletes’ comprehensive ability into a new way of scientific quantitative measurement and evaluation, which will provide a scientific basis for the selection of combat vibration items, the regulation of training process, the inspection of training effect, and the formulation of enrollment and examination standards for sports colleges and universities. The results show that the instrument can obtain the parameters of hitting strength, strength endurance, hitting speed, speed endurance, hitting impulse, and hitting power of sports biomechanics on the group of fighting events, which provides a reliable basis for coaches to implement teaching and training for athletes.

SCN9A rs6746030 Polymorphism and Pain Perception in Combat Athletes and Non-Athletes

One of the genes associated with pain perception is SCN9A, which encodes an α-subunit of the voltage gated sodium channel, NaV1.7, a crucial player in peripheral pain sensation. It has been suggested that a common missense polymorphism within SCN9A (rs6746030; G>A; R1150W) may affect nociception in the general population, but its effects of pain perception in athletes remain unknown. Therefore, the aim of the study was to investigate the association between a polymorphism within SCN9A (rs6746030) and pain perception (pain threshold and pain tolerance) in the group of combat athletes (n = 214) and students (n = 92) who did not participate in sports at a professional level. Genotyping was carried out using TaqMan Real-Time PCR method. No significant differences were found between the SCN9A genotype distributions with respect to the pain threshold. However, the probability of having a high pain threshold was higher in the combat sports group than in the control group. The probability of having a decreased pain tolerance was higher in the carriers of the GA and AA genotype than in the homozygotes of the GG genotype. Moreover, the possibility of having a high pain threshold was higher in the combat athlete group than in the control group. The results of our study suggest that the SCN9A rs6746030 polymorphism may affect pain perception. However, the additional effect of the experimental group may suggest that pain tolerance is significantly modulated by other factors, such as the systematic exposure of the athletes' bodies to short-term high-intensity stimuli during training sessions.

Croatian Combat Athletes’ Attribution Patterns for Their Successes and Failures

Successes and failures are integral outcomes to the sport experience. Based on decades of research, how athletes process both outcomes influence their thoughts, emotions, and subsequent achievement endeavors. Attribution theory details three dimensions as to the causes of success and failure. Since the 1980s, attribution theory has found a home in sport psychology literature. However, research across countries requires valid and reliable questionnaires. One such country is Croatia where attribution research is scant. Thus, in a Croatian combat athlete sample, we examined athletes’ attributions for the most and least successful performances via retrospection. Croatian athletes (N = 154) from three combat sports (judo, karate, and taekwondo) who all competed at least once on an international stage completed the Croatian Causal Dimension Scale-II, answered in reference to a specific reason for their best and worst competitive experience. Results showed that the combat sport athletes attributed their most and least successful competitive achievement to psychological reasons more than other reasons (i.e., general preparation and physical preparation). Furthermore, based on a series of two-tailed paired samples t-tests and the nonparametric equivalent, Wilcoxon signed rank test, the participants made, from small to medium in meaningfulness (Cohen’s d), more internal (d = 0.30), stable (d = 0.56), personal (d = 0.30), and external (d = 0.21) controllable attributions for success than for failure (all t-test p-values < 0.01). Our results suggest the athletes made the self-serving attribution bias across both the success and failure competitive events. Our results contribute to better understanding of specific reasons for success and failure and the attribution dimensions explaining the competitive outcomes in competitive combat sport. Specific to Croatian sport, our results provide Croatian combat sport with theory driven research applicable to improving development of Croatian combat athletes on the international stage.

Static Postural Control during Single-Leg Stance in Endurance, Team and Combat Athletes from the Spanish National Sport Technification Program

In the context of pediatric physical exercise, the analysis of factors affecting postural control (PC) provides insight into the development of sport-specific motor skills. This study aims to evaluate the static PC during single-leg stance in endurance, team and combat athletes from the Spanish National Sport Technification Program. A total of 29 boys and 32 girls, aged 12 to 16 years old, were recruited. Centre of pressure (CoP) was measured on a force platform in standing position for 40 s under two sensorial and leg dominance conditions. Girls showed lower MVeloc (p < 0.001), MFreq (p > 0.001) and Sway (p < 0.001) values than boys in both sensorial conditions (open and closed eyes). The highest values in all PC variables were observed with eyes closed in both genders (p < 0.001). Sway values were lower in boys combat-athletes compared to endurance athletes in two sensorial conditions and with non-dominant leg (p < 0.05). Young athletes in their teens enrolled in a Sport Technification Program have shown differences in PC when comparing different visual conditions, sport disciplines and gender. This study opens a window to a better understanding of the determinants of PC during single-leg stance as a critical element in the sport specialization of young athletes.

Prevalence of disadaptive eating behavior among sports university students

BACKGROUND: Numerous studies have proven the importance of studying the actual nutrition of student youth. However, the prevalence of maladaptive eating behavior (EB) among student-athletes and non-athletes remains unexplored.&#x0D; AIM: to assess the prevalence of maladaptive EB among students of a sports university.&#x0D; METHODS: a survey was conducted of 768 students of the Volga Region State University of Physical Culture, Sports and Tourism using the Eating Behavior Assessment Scale (EBAS). Statistical analysis of the results was performed using SPSS Statistics v. 19.0 (IBM, USA).&#x0D; RESULTS: Оnly 41.11.8% of students of a sports university have no signs of maladaptive EB. The presence of deviations according to the subscales of EBAS was revealed in 72.94.5% of martial artists, 57.84.6% of athletes of complex coordination sports and 55.84.2% of cyclic sports, 55.03.2% of players and 59.43.7% of non-athletes. However, no statistically significant gender differences were found. Clinical symptoms of maladaptive EB were detected in 10.32.3% of non-athletes and 8.61.2% of athletes. At the same time, in student-athletes of individual sports, they were detected 1.7 times more often than in team sports (2=22.36; df=9; р=0.008). Psychological characteristics and stereotypes of behavior characteristic of people with maladaptive EB were found in 33.13.6% of non-athletes and 28.51.9% of student-athletes.&#x0D; CONCLUSION: Among the university sports students, there is a high prevalence of maladaptive EB among combat athletes. Whereas, among athletes, and female athletes of team sports, as well as young men and women who do not participate in sports, clinical symptoms of maladaptive EB have been relatively uncommon, however, psychological and behavioral stereotypes typical of persons with maladaptive EB are more often detected, which can be considered as a high predisposition to the development of such conditions.

The use of the multicomplex sports nutrition "MDX" in martial arts athletes

The composition of the diet is very significant for the development of various physical qualities in humans. The use of balanced supplements has a positive effect on the body’s condition and increases the success of trainees in many sports. One of the options for optimizing nutrition for athletes can be the use of the sports nutrition multicomplex MDX. This product is obtained by microbiological processing of whey followed by low-temperature thickening. It contains oligopeptides and free amino acids, glucose, galactose, nucleic acids, a number of vitamins and microelements, betacarotene, ergosterol, folic acid, endosomal enzymes of lactic acid bacteria. In addition, the product contains a live culture of lactic acid bacteria: L. Lactis, L. Thermophyilus, L. Bulgaricus. Hand-to-hand fighters, judokas and Greco-Roman wrestlers took part in the work. Athletes (70 males: adolescents and young men) regularly took this product according to the following scheme: five days 1g/kg body weight and two days off. The daily dose was divided into two parts. Combat athletes took one part 30 minutes before the start of training, the second they took 30 minutes after the end of training. It was found that among the sports specializations taken into account, judoists who received the multicomplex MDX sports nutrition had the highest speed. They were faster than hand-to-hand fighters and fighters.

The Dark Triad and Professional Fighters: Destigmatizing Male Combat Athletes.

Personality characteristics have long been studied in relation to athletes and their performance. Of these, emotional self-regulation has been determined to be an important factor regarding outcomes for athletes. Various research has examined the Dark Triad (Machiavellianism, narcissism, and psychopathy) among other personality traits in athletes. However, little research has examined Dark Triad levels in combat sports professionals and their impact on their athletic performance. Since professional fighting athletes have been perceived as aggressive and impulsive, it is essential to examine the athletes' level of Dark Triad traits. The present exploratory study investigates the association of Dark Triad personality traits in professional fighters versus college-aged male non-fighters. Secondly, it aims to evaluate the relationship between Dark Triad traits and winning percentages in professional fights. The study used a sample of professional male fighters (n = 36) and college-aged non-fighters (n = 29). Participants completed measures examining emotional self-regulation, trait anxiety, sensation seeking, and Dark Triad personality traits. The results of our study showed no significant differences in Machiavellianism, psychopathy, and narcissism between our samples of professional fighters and college-aged nonfighters. The study also showed no significant correlations between winning percentages for professional fighters and Machiavellianism, psychopathy, or narcissism.

Study of the reaction of the choice of combat athletes using computer technology

Purpose: to develop a methodology for evaluating the reaction of the choice of combat athletes using computer technologies and to conduct research on testing and determining its validity. Materials, participants and methods: the total number of participants in the study was 77 people (mean age: 13.8±0.7 years, 28% girls, 72% boys). To evaluate the choice reaction, the computer program «Visuomotor Choice Reaction» for mobile devices was developed and implemented. The following methods have been studied: analysis of scientific and methodological information and Internet sources; summarizing best practices; computer programming method; methods of mathematical statistics. Results: the study was carried out in three stages. At the first stage, the correspondence of the selected colors and shapes to the tasks that should be solved during the test was determined. Measuring the speed of response to a single color and to individual shapes showed that the values are evenly distributed, the range of variation for the response to color was 50,7 ms, and the response to shapes was 133,4 ms. At the second stage, indicators of the reaction of choice were obtained and the operation of the computer program was tested in the "field conditions". The practical application of the program made it possible to obtain indicators of the reaction of the choice of taekwondo novice athletes and determine the stability of its work. The obtained data of the third stage determined the reliability and validity of the proposed method for assessing the reaction of choice. Conclusions: based on the analysis of scientific and methodological literature and the competitive activity of martial artists of various specializations, conversations with coaches and qualified athletes, a computer program «Visuomotor Choice Reaction» was developed to assess the choice reaction. According to the results of the study of the reaction of choice of taekwondo novice athletes using the proposed methodology, in order to test it, it can be argued that the «Visuomotor Choice Reaction» computer program allows you to obtain indicators of sensorimotor reactions, is simple and reliable when using it. According to the results of the correlation and dispersion analysis, it can be argued that the proposed method for assessing the choice reaction is reliable and has a significant level of validity and meets all metrological requirements.

Performance Level and Strike Type during Ground and Pound Determine Impact Characteristics and Net Force Variability.

The evaluation of strike impact is important for optimal training, conditioning and tactical use. Therefore, the aim of this study was to evaluate ground and pound strikes, in terms of net force variability, across genders and performance levels. Eighty-one participants, professional men (n = 8, 37 ± 6 years, 195 ± 7 cm, 113 ± 27 kg), advanced men (n = 47, 26 ± 8 years, 180 ± 7 cm, 76 ± 11 kg), and advanced women (n = 26, 21 ± 1 years, 167 ± 6 cm, 61 ± 7 kg) performed three strikes from a kneeling position into a force plate on the ground. The elbow strike resulted in the highest impulse and the palm strike in the highest peak force for all three categories. These results support the recommendation that has previously been made to teach the palm strike to beginners and advanced tactical and combat athletes. The direct punch and elbow strike net force were characterized by a double peak curve, where the first peak variability explained 70.2-84% of the net force. The second peak was pronounced in professional men during elbow strikes, which explained 16% of net force variability. The strike type determines the impact net force and its characteristics, where palm strike is typical by highest peak impact tolerance and elbow strike by double force peak with high net force impulse.

Структурно-функциональные и нейрофизиологические аспекты обеспечения спортивной деятельности кикбоксеров (обзор)

The analysis of scientific and methodological literature revealed very few works on the neurophysiology and development of physical qualities in kickboxers. Papers of recent years focus on high-level athletes. However, the structural-functional and neurophysiological features of kickboxers’ sports activities in the process of perfecting their skills remain insufficiently studied. For kickboxers, the key physical abilities playing an important role in fulfilling sports potential and achieving high results include strength, speedstrength, technical-tactical, and psychological abilities, as well as endurance. In scientific literature, the psychophysiological status of a combat athlete is determined based on the methods evaluating sensorimotor reactions of different modalities and complexity. As kickboxers reach higher levels in their sport, we observe optimization and economization of structural and functional adaptation mechanisms in the nervous, neuromuscular, and sensorimotor systems. Studies on neurophysiological adaptive changes in response to physical loads in combat athletes (including kickboxers) reflect multidirectional results. For instance, it has been established that the activity of the sympathetic nervous system in combat athletes increases at normotonia during the competitive, while at sympathicotonia, during the preparatory period. Other studies demonstrate that this group of athletes has optimal adaptive reserves and higher adaptive capacity of the heart compared to representatives of other sports. A personalized training process with specialization in kickboxing should be organized taking into account athletes’ individual neurophysiological profiles in order to choose the means, methods and level of the training and competitive loads to achieve the goals set.

Prevalence of rapid weight loss in Olympic style wrestlers.

ABSTRACTBackgroundThe methodology applied for rapid weight loss (RWL) among elite wrestlers is quite unexplored. Therefore, the aim of this study was to analyze the prevalence of sources of influence and methods used for RWL and to determine the differences between wrestling styles.MethodsA total of 229 wrestlers who competed at the World Championship held in Belgrade, Serbia, participated in this research. All respondents completed a questionnaire designed to evaluate RWL patterns in combat athletes. Participants were classified according to wrestling style: Greco-Roman, freestyle, and women wrestling.ResultsSixty-nine percent of wrestlers had previously lost weight to compete. Most respondents start losing weight approximately seven days before a competition. Athletes reported that they commonly reduced 3.84 ± 2.82 kg to reach the target weight. The wrestling coach represents the most influential person in terms of RWL strategies, while nutritionists and physicians have the least impact on the weight-cutting process. Regarding the methods applied, differences between all the three styles were found in the following variables: training in a heated room, restricting fluid ingestion, training in plastic suits, gradual dieting, increased exercise, diet pills, and sauna. The most frequently used techniques were increased exercise, gradual dieting, training in a heated room, and sauna for all competitors. Diet pills, diuretics, laxatives, and vomiting were the least implemented methods.ConclusionsThe obtained results suggest that most wrestlers practice RWL despite the harmful health effects. The education of wrestling coaches is necessary in order to control and decrease the negative impact of RWL.

Virtual reality boxing: Gaze-contingent manipulation of stimulus properties using blur.

It has been reported that behavior of experts and novices in various sporting tasks is impervious to the introduction of blur. However, studies have used diverse methods of blurring the visual stimulus (i.e., dioptric blur and Gaussian blur), and tasks that did not always preserve the normal perception-action coupling. In the current study, we developed a novel experimental protocol to examine the effect of different levels of Gaussian blur on interception performance and eye gaze data using an immersive VR task. Importantly, this provided a realistic simulation of a real-world boxing scenario (e.g., the presence of a feint prior to the onset of different combinations of punches) in which expert combat athletes (n = 18) experienced a first-person, adaptive viewpoint of the visual environment, which could be blurred according to their gaze location (central blur, peripheral blur, no blur). We found that participants exhibited similar interception performance in the presence of central blur or peripheral blur compared to a control condition with no blur. However, interception performance was significantly better with a central blur compared to peripheral blur. Eye gaze data indicated that although participants fixated at similar areas of interest irrespective of the presence of blur, fixation duration was significantly longer with a strong level of blur in the peripheral viewing condition than all levels of central blur and the control condition. These findings can be explained by relocating attention to different areas of the environment, which thereby influenced the perception of salient information. Participants also performed better on the first punch of a sequence preceded by a foot feint compared to arm feint or no feint. Still, irrespective of feint type, performance was significantly better on the second and third punch compared to the first punch. These findings are consistent with participants using additional information from the opponent's body movements and situational probabilities to increase performance as the sequence of punches developed. Overall, these are the first evidence for the use of VR as a means to examine gaze-contingent manipulations of the environment, and hence highlight the potential for facilitating learning and transfer to a real sporting situations.

Effect Of Acute Feeding Status On Substrate Oxidation Rates In Runners And Combat Athletes During Submaximal Exercise Tests

Background: The degree to which feeding and sport background together impact substrate oxidation is not clearly understood. Purpose: To discern the effect of feeding status on substrate oxidation during submaximal exercise tests in runners and combat athletes using a crossover design. Methods: Two submaximal tests were performed using a novel graded submaximal treadmill protocol, with a different feeding status prior to each test. Athletes were either fasted for 8 hours or were given a 200-kcal carbohydrate gel snack 30 minutes prior to testing. Oxidation rates of glucose and fatty acid were derived utilizing gas exchange data values. A within-subjects repeated-measures ANOVA was performed to analyze the impact of feeding status on substrate oxidation rates. Results: A total of 24 male athletes (17 runners, 7 combat athletes) were included in the study. Participants were 32.5 ± 11 years of age, with an average VO2max of 47.6 ± 9 mL/kg/min. Mean body weight, height, body mass index (BMI), and body fat percentage was 75.1 ± 7.5 kg, 174.8 ± 5.2 cm, 24.7 ± 2.6 kg/m2, and 15.8 ± 5.7%, respectively. Mean fatty acid oxidation rate while fasted and fed was 0.45 ± 0.11 and 0.21 ± 0.12 g/min, respectively for runners, and 0.30 ± 0.09 and 0.26 ± 0.07 g/min, respectively for combat athletes. Mean glucose oxidation rate fasted and fed was 1.14 ± 0.25 and 1.48 ± 0.30 g/min, respectively for runners, and 1.27 ± 0.32 and 1.42 ± 0.15 g/min, respectively for combat athletes. There was a statistically significant effect of pre-test feeding status on both fatty acid and glucose oxidation rates among runners and combat athletes, F(1,22) = 20.870 (P < 0.001) and F(1,22) = 22.410 (P < 0.001), respectively. There was a statistically significant difference in fatty acid oxidation rate based on feeding status between runners and combat athletes (P = 0.003), but not on glucose oxidation rate (p = 0.078). Conclusion: Both feeding status and sport background contributed to substrate oxidation rate. Runners were able to oxidize a greater amount of fatty acid when fasted, while combat athletes were able to oxidize a greater amount of glucose. Runners exhibited higher amounts of glucose oxidation when fed, while combat athletes exhibited higher amounts of fat oxidation. More research is required on larger sample sizes to further elucidate our findings.
