The effect of 8-weeks wrestling training on unilateral muscle imbalances

Background and Study Aim. This study aimed to investigate the effect of 8-weeks of wrestling training on unilateral muscle imbalances.
 Material and Methods. Eight male elite Greco-Roman wrestlers (wrestling group) (age 21.25±2.7 years, height 176.6±6.8 cm, body weight 81.00±9.3 kg) and seven recreationally active male (control group) (age 21.3±3.2 years, height 173.6±4.7 cm, body weight 67.3±5.3 kg) voluntarily participated in the study. Both group participants were students in the Selcuk university in the period of study. Wrestlers were in the off-season before the training period of 10 weeks. Before and after the 8-weeks training period, wrestling and control groups were tested for isokinetic torque measurement. In the training period, the wrestling group carried out only wrestling training without specific strength training. In this period the control group did not involve in any exercise.
 Results. In the wrestling group, all quadriceps torque parameters significantly increased for both legs but the torque parameters of the hamstring did not change, except the average torque of the left leg. The peak and average torque of the H/Q (Hamstring/quadriceps) significantly decreased after training periods for right leg in the wrestling group. No parameters significantly changed in the control group.
 Conclusions. Specific hamstring strength exercises can be put in training programs to avoid from a possible knee injury.

The Effects of Beetroot Juice Supplementation on Balance Performance of Wrestlers

Aim: This study assessed the effect of beetroot juice supplementation on the dynamic and static balance performance of wrestlers at rest and fatigue conditions. Material and methods: The study was conducted with 3 trial days. The study is a double blind, randomized, cro ssover design in which eight trained male Greco Roman wrestlers (age 21.87±2.3 years; height 176.87± 4.1 cm; body weight 76.75± 5. 4 kg) consumed beetroot juice (BRJ) (140 ml) or placebo (PLA) (140 ml, cherry juice with lemon juice) 150 min before performin g balance performance test. Subjects were administered standard warm up and then dynamic and static balance tests were performed to the dominant leg with by Biodex Balance System (BBS, Biodex Medical Systems Inc., Shirley, NY) at rest. Following balance te sting, each subject got into a fatigue strength exercise (FSE) to create fatigue for the dominant leg. Immediately after the ( FSE), subjects were applied to dynamic and static balance test to the dominant leg again at fatigue. The same trial procedure was repeated with the other supplement (BRJ or P LA ) in the third testing trial five days later. Paired sample T test was used for comparison of BRJ and P LA balance performance values. Result: Although there were no significant changes in static OSI, APSI balance scores, Static MLSI improved significantly in favor of BRJ in rest . Dynamic OSI and APSI paramet er s improved significantly but not MLSI in the BRJ trial. While all static and dynamic b alance parameters improved statistically, only static MLSI w as not changed by the BRJ trial at fatigue. Conclusion: Consuming BRJ can be useful to maintain balance performance and prevent sports injuries in training or competition. Keywords: Beetroot Juice, Dietary Nitrate, Balance, Wrestlers.

Постнавантажувальна динаміка варіабельності артеріального тиску на кожному серцевому скороченні у висококваліфікованих атлетів

Using Spiroarteriocardiorhythmography (SACR), 202 highly qualified male athletes, aged 22.6 ± 2.8 years, representing acyclic sports: martial arts (karate, taekwondo, kickboxing, boxing, freestyle wrestling, Greco-Roman wrestling, judo, sambo) and games (water polo, football) were examined. Sports experience was 10.3 ± 3.1 years. All studies were carried out in the pre-competition period. In accordance with the design, the examination with the use of SACR were carried out three times: in the morning, on an empty stomach, in a sitting position on the day of training (G1), immediately (in the first 5-7 minutes) after training (G2) and the next day in the morning after sleep (G3). The duration of each registration was 2 minutes. The spectral parameters of the variability of systolic (SBPV) and diastolic (DBPV) pressure and their derivatives – baroreceptor sensitivity (BR) and indices of heart rate centralization (ICHR), systolic (ICSBP) and diastolic (ICDBP) pressures were determined.

Identification of success factors in elite wrestlers-An exploratory study.

Identification of success factors in wrestling as well as establishing their hierarchy are crucial from a cognitive and practical standpoint. It may provide a lot of practical recommendations related to wrestling-specific training. The aim of this study was to identify and establish the hierarchy of success factors in wrestling regardless of a fighting style and weight class. This study included 168 elite male freestyle and Greco-Roman wrestlers. They were divided into two groups: athletes who won medals (successful wrestlers) in high-rank competitions (Polish Championships or higher) and those who did not win any medals (less successful wrestlers) in those competitions. The following elements were assessed: anthropological measurements, body composition, dynamic strength, strength endurance, agility, special endurance, wrestling-specific fitness, response time, technical wrestling skills and anaerobic capacity. For initial data analysis, one-way ANOVA (α = 0.005) was used. Random Forests classifier was employed to identify success factors and to determine the importance of each of these factors in terms of sports performance. Seven key success factors were identified: anaerobic power, strength endurance, response time, special endurance, wrestling-specific fitness and technical wrestling skills performed in a horizontal position. Random Forests turned out to be an effective method of modelling success in wrestling (compared to SVM and KNN, which were also used in the study). These findings suggest that wrestling-specific training can be effectively monitored by controlling several vital indicators of athletes’ preparedness: anaerobic power, strength endurance, response time, special endurance, wrestling-specific fitness and technical wrestling skills (the performance of reverse waistlock from a standing position and trunk grip gut wrench assessed by experts).

Energy pathway contributions during 60-second upper-body Wingate test in Greco-Roman wrestlers: intermittent versus single forms

ABSTRACT This study aimed to investigate the energy pathway contributions and physiological and performance responses between a 10 × 6-second intermittent sprint test (IST) and a 60-second single maximal test (SMT). Seventeen highly trained male Greco-Roman wrestlers participated in this study. Participants completed the 60-second upper-body Wingate tests, both intermittent and single forms. The contributions of the oxidative, glycolytic, and ATP-PCr pathways were estimated using mathematical methods based on lactate values and oxygen consumption kinetics of rest, exercise, and recovery phases. The main findings indicated that total energy expenditure (TEE) and the contribution of oxidative, glycolytic, and ATP-PCr pathways were 514 kJ, 45%, 11%, and 44% for IST (overall: sprints + rest intervals); 333 kJ, 14%, 17%, and 69% for IST (sprints only); and 159 kJ, 31%, 38%, and 31% for SMT, respectively. TEE and ATP-PCR pathway contributions were higher in the IST (both overall and sprint only), whereas glycolytic pathway contribution and delta lactate were higher in the SMT. Absolute oxidative contribution was similar, but relative oxidative contribution was higher in the SMT. Additionally, mean power was higher in the IST than SMT, whereas peak power, peak and mean heart rate, and ratings of perceived exertion were similar.

Comparison between seated medicine ball throw test and Wingate test for assessing upper body peak power in elite power sports players

Objectives: Upper limb explosive power is an important motor quality for sporting performance and indicates use of anaerobic energy systems. The Wingate Anaerobic Test (WAnT) has been considered to be a valid and reliable tool for the assessment of anaerobic power and functional performance of elite athletes. However, it is expensive and a lab based test and requires skilled manpower. The seated medicine ball throw test (SMBT) is inexpensive, easy to assess and since equipment required is minimal, it can be easily used as a field test. Hence, the purpose of the study was to determine if the SMBT method could be used as an alternative for WAnT test so that a reliable and inexpensive test is available for athlete monitoring and talent identification screening. Materials and Methods: Male elite athletes aged 18–30 years (n = 100), who were involved in national level competition of three sports discipline, namely, Boxing (n = 34), Wrestling Greco-Roman (GR) (n = 36), and Wrestling Freestyle (FS) (n = 30), were tested on crank-arm ergometer for WAnT and SMBT to measure an peak power or explosive power for the upper body. Results: SMBT test results were significantly positively correlated with upper body peak power measured by WAnT in all sportsmen (r = 0.55, P = 0.0002). One sample t-test results showed that the mean difference between SMBT and peak power is close to zero among Boxers (P = 0.13) and FS wrestlers (P = 0.89) and GR Wrestlers (P = 0.49). Overall, 97% pairs of SMBT and peak power were within the limits of agreement among all sportsmen, showing that results using both the tests were agreeable. Conclusion: This study suggests that SMBT tests could be used as an alternative field test to measure anaerobic power in Wrestlers, Boxers, and sports where the involvement of upper body muscles take place predominantly. In addition, the SMBT protocol used in this study provides an easy way for the coaches to assess the athletes on the field during talent identification and also to evaluate their training program.

Quantity and quality analysis of scores showed that FS wrestlers significantly scored more 1- and 4-point, while GR wrestlers were superior regarding the quality 2-point. The average competition efficiency of gold medallists was 18/43±4/67 in FS and 15/87±3/18 in GR which were statistically significantly greater than that of all other placers.
 Conclusion. This study showed the dominance of LAC in a wrestling match in both styles, although their relative contribution was significantly different between styles. In addition, FS wrestlers significantly scored more points, and Gold medallists demonstrated the greatest average competition efficiency compared to other medallists.

МЕТОДИКА СПЕЦИАЛЬНОЙ ТЕХНИЧЕСКОЙ ПОДГОТОВКИ НА ОСНОВЕ СОВЕРШЕНСТВОВАНИЯ ПСИХОФИЗИОЛОГИЧЕСКИХ ОСОБЕННОСТЕЙ БОРЦОВ ГРЕКО-РИМСКОГО СТИЛЯ

The modern level of sports achievements means a lot for the quality of training of Greco-Roman style wrestlers. Competitive duels are characterised by a high intensity of technical and tactical actions that require their effective implementation in a rapidly changing environment. The level of sportsmanship of Greco-Roman style wrestlers is largely determined by individual characteristics and the ability to effectively, with a high degree of reliability, apply technical actions, which are largely related to the level of psycho-functional readiness of the wrestler. The article presents the method of special technical training developed by the authors on the basis of improving the psycho-physiological features of Greco-Roman style wrestlers.

The determinants for top ranker of Korean Greco-Roman wrestlers

Background and objective: This study investigates the physical factors that determine the top ranker players based on the Greco-Roman wrestlers in the national athletic team of South Korea. Additionally, the study developed a prediction model using physical factors. For this analysis, the data of 163 players in the last 20 years (1999–2018) available on the Athletic Competition Performance Assessment Computer System were used. A top ranker was defined as an athlete who had won a medal in a world championship or the Olympic Games. Methods: The logit model was used as the model and the estimations were performed using maximum likelihood estimation (MLE) with E-views9.5 (Lightstone Corp., Tokyo, Japan). The estimation results demonstrated that the probability of becoming a top ranker increased with the following: increase in the length of the career compared to age, increase in the distance of standing long jumps, decrease in response time to light, and increase in bench press weight. Results: The analysis of the model’s estimation results showed that superior results were produced when the standing long jumps, response time to light, and bench press weight were normalized using the weight class based on McFadden R2, Akaike Information Criterion (AIC), and Schwarz information criterion (SBIC) as compared to when they were normalized using the height and body weight. Conclusion: The estimation model established in this study for the significant physical strength factors shown in the South Korean top rankers is expected to be used as important data for predicting and fostering world-class South Korean Greco-Roman wrestlers.

The effects of acute beetroot juice supplementation on lower and upper body isokinetic strength of the wrestlers

Background and objective: Peak torque, as measured by the gold standard method of isokinetic dynamometry, is affected by consumed of dietary nitrate (NO3−) in the form of beetroot juice (BRJ). The increasing strength performance effect of BRJ has also started to arouse interest in combat sports. This study aims to investigate the effects of acute dietary nitrate supplementation on lower and upper body isokinetic strength of trained Greco-Roman wrestlers.Materials and methods: The study is a double-blind, randomized, crossover design in which eight trained male Greco-Roman wrestlers (21.87 ± 2.3 years; height 176.87 cm ± 4.1 cm; body weight 76.75 kg ± 5.4 kg) consumed beetroot juice (140 mL) or placebo (140 mL, cherry juice with lemon juice) 150 min before performing isokinetic strength. Participants performed knee extensors and flexors and shoulder internal and external rotator isokinetic strength test (in the dominant limbs) concentrically at 60◦ with by Cybex device (Cybex NORM®, Humac, CA, USA). The same trial procedure was repeated with the other supplement (BRJ or Placebo) in a second testing session five days later. BRJ and Placebo trials' isokinetic strength values were compared with parametric testing (paired sample T-test).Results: Although there was a significant difference in peak torque of shoulder internal and external rotator values in favor of BRJ (P < 0.05), there was no significant difference in the knee strength test. Additionally, all average isokinetic strength values were significantly increased in the BRJ trial (P < 0.05).Conclusions: These results suggest that BRJ can be used as an ergogenic effect for improving strength values in Greco-Roman wrestling.

Determining the number of repetitions to establish isokinetic knee evaluation protocols specific to angular velocities of 60°/second and 180°/second

IntroductionThis study aims to develop a standard number of repetition at angular velocities of 60°/sec and 180°/sec and define the difference of number of repetitions between genders. MethodOne hundred ninety-six athletes (judo, volleyball, Greco-Roman wrestling, runners, and gymnastics) were involved. Concentric-concentric isokinetic muscle strength of the knee flexor-extensor muscles of the athletes were performed with an ISOMED 2000 isokinetic dynamometer. The evaluation test protocol consisted of 10 repetition of knee flexion-extension at 60°/sec and 30 repetitions at 180°/sec. ResultsAthletes performed with maximal knee flexion strength at their second and third trial at 60°/sec and third-forth trial at 180°/sec. It was found that 2 repetitions and 2–3 repetitions were needed for knee extension peak torque at 60°/sec and 180°/sec respectively. The difference between the genders was significant at 60°/sec for knee flexion and extension on the dominant side; at 180°/sec for knee extension on the dominant and non-dominant side. It was determined that 3 repetitions for 60°/sec, 4 repetitions for 180°/sec were enough to determine peak torque values. DiscussionOptimal number of repetitions is crucial so that athletes could have the opportunity to reach maximal strength without unnecessary workload or waste of time. ConclusionsProtocols involving 3 repetitions for 60°/sec, 4 repetitions for 180°/sec were enough to determine peak torque values. Gender of athletes should be considered when establishing isokinetic knee evaluation protocols.

IMPROVEMENT OF PSYCHOMOTRICITY FOR JUNIOR WRESTLERS USING STRENGTH TRAINING EXERCISES

The use of objectifying skills and behavioural techniques of wrestlers in training and competitions is not that old. The measurement and evaluation of the predictability components of competitive performance in the sport of wrestling is more important, given that there are no clear elements for performance quantification in this category of sports. The conversion of these components into figures allows to obtain results through which we can define their share and impact on creating competition and training models and the selection model, planning, monitoring and evaluating the effectiveness of training methods and in particular developing refined solutions by which the most efficient ways of progress can be obtained. As the field of sports training becomes more intense and competitive, coaches and scientists in the field of sports training and competition direct their concerns towards developing the best training and education content in order to improve sports performance from an early age. Our opinion is that this potential for performance is not exploited, because we are currently going through an information crisis and especially a crisis of specialists who can use this information to increase the efficiency of training children in the sport of wrestling. This study highlights the role of strength exercises in the optimisation of skills whose impact is essential, we believe, in the technical training of Greco-Roman and freestyle wrestlers and an indispensable element of future competitive behaviour.

Immediate Effect of Local Vibration Therapy for Sport-induced Fatigue Based on Traditional Chinese Medicine's Holistic Theory.

IntroductionVibration therapy has been widely used and published in alleviating muscle fatigue. However, reports on applying vibration therapy based on the holisitic theory of traditional Chinese medicine (TCM) remains limited. This study is to evaluate the immediate effect of vibration therapy on exercise-induced muscle fatigue.MethodsFor this retrospective parallel controlled study, all data were from a previously approved and completed clinical trial. Participants (n=40) in the clinical trial included local Greco-Roman wrestling and Judo athletes in south China. The participants were equally randomly divided into the intervention group (n=20) and control group (n=20). The intervention group received a seven-week vibration intervention-based TCM holistic theory combined with conventional therapy, such as stretching, massage, and flapping, while the control group only received the conventional therapy. Surface electromyography (sEMG) of the lumbar segment of erector spinae was measured for each participant pre- and postintervention, and the two-point discrimination thresholds of the data were differentiated and compared with panel data analysis.ResultsFor the control group, the pre- and postintervention sEMG measure showed no significant difference (p=0.333), whereas significant difference (p=0.004) was observed for the intervention group. Further, the pre- and postintervention two-point discrimination test also showed a significant difference (p=0.016) for the intervention group.DiscussionThe application of vibration therapy based on TCM holistic theory may have an immediate effect in reducing sport-induced muscle fatigue from intensive training. Future larger sample size and robust designed clinical trial is warranted to evaluate the long-term effect of the intervention.

Ratio and interconnections of functional fitness structure key components of elite combat athletes at the stage of maximum realization of individual capabilities

Background and Study Aim. The objective of the work consisted in studying the ratio and interconnections of functional fitness structure key components of elite combat athletes in the process of adaptation to physical loads at the stage of individual capacity maximum realization.&#x0D; Material and Methods. 55 highly skilled wrestlers aged 19-27 years old, members of the national teams of Ukraine in different styles of wrestling - freestyle, Greco-Roman, judo were examined. The assessment of wrestlers’ functional fitness structure was made according to a complex of indices of physiological systems activity at rest and during performance of a block of testing physical loads on a bicycle ergometer.&#x0D; Results. The components of functional fitness structure of male combat athletes of three wrestling styles (Greco-Roman, freestyle and judo) were studied according to the manifestations of the respiratory and circulatory functions during testing loads performance, and achieved indices of work capacity. It has been revealed that the key integrative components of the general structure of wrestlers' fitness include: the level of special work capacity, general level of functional fitness, mobility of physiological processes, economy, anaerobic power. Greco-Roman wrestlers are superior to freestyle wrestlers and judokas in anaerobic power, mobility and economy. The greatest differences are manifested in the values of anaerobic power, mobility and general level of functional fitness, whereas the least - in indices of economy. The key criteria for the functional fitness of wrestlers in the manifestation of a high level of physical work capacity include: economy of functioning at rest and during muscular activity of anaerobic-aerobic nature, high reactivity of the cardiovascular system to physical load, power of the anaerobic energy supply system, the rate of recovery processes, the state of cardiac activity regulatory mechanisms, the level of metabolic processes and excitability of the heart muscle. The level of development and the ratio of the components of functional fitness structure of elite combat athletes may be used as the reference models for development of differentiated scales for estimation of the key constituents of physical state of wrestlers specialized in freestyle, Greco-Roman wrestling and judo. Complex application of different methods of testing athletes provides more efficient approach to the problem of monitoring and managing functional fitness and special work capacity of wrestlers at the stage of maximum realization of individual capacities.&#x0D; Conclusions. An increase in the proportion of key integrative functional indices in special work capacity of athletes specialized in various wrestling styles - Greco-Roman, freestyle and judo represents the most significant criterion for improving their functional fitness structure.

Особливості систем відбору спортсменів-кандидатів у національну збірну команду України для участі в іграх олімпіад (на прикладі спортивних єдиноборств)

The article presents the analysis of the peculiarities of the selection systems for athletes-candidates to the Ukrainian national team for participation in the Olympic Games (on the example of combat sports). The urgency of the work is due to the need to develop and implement a modern model of Olympic training in combat sports, which would allow the athletes to compete successfully in the international arena. The purpose of the study was to determine the features of the current selection systems for athletes-candidates to the Ukrainian national team to participate in the Olympic Games (on the example of combat sports). Material and methods. Theoretical analysis, generalization of literature and Internet data, documentary method allowed to identify trends in modern Olympic combat sports and analyze the selection systems governing the inclusion of Ukrainian athletes in the starting lineup of participants in the Olympic Games in modern combat sports (fencing, boxing, Free and Greco-Roman wrestling, judo, taekwondo, karate). Results and discussion. Most of the provisions of the selection systems for athletes-candidates to the Ukrainian national team to participate in the Olympic Games are similar. In most combat sports, selection is based on an analysis of the performances of athletes in national and international competitions, competitiveness and the results of personal fights with major rivals who will participate in the Olympic Games. Selection for the starting lineup of the team at the main competitions of the season or four-year Olympic cycle consists of several stages, each of which determines a different number of athletes-candidates for the national team. As the year of the next Olympic Games approaches, the number of candidates is decreasing proportionally. The peculiarity of all systems of national selection in modern Olympic combat sports is that the athlete needs to realize his (her) potential in almost every competition during the annual macrocycle, as it depends on the prospect of his inclusion in the starting lineup of the national team at major competitions. Taking into account the fact that the body's adaptive capabilities are limited, it is important to determine the appropriateness of the athlete's performance in a particular tournament, taking into account his (her) position in national and world rankings, and other conditions governing its inclusion in the starting lineup. Conclusion. Differences in the selection systems are the mechanisms for determining the starting lineups of the team in the main competitions of the season or four-year Olympic cycle (demonstration of a certain result or winning a place in a particular tournament, position in the world rankings, obtaining an Olympic license)

Physiological criteria of functional fitness and determinants of physical work capacity of highly skilled wrestlers

Background and Study Aim. The objective of the work is to study the key factors of highly skilled wrestler fitness structure determining the level of their functional state and physical work capacity at the stage of maximum realization of individual capacities. Material and methods. 45 highly skilled wrestlers aged 19-27 years, members of the national teams of Ukraine in freestyle and Greco-Roman wrestling were examined. 27 athletes of student age (19-24 years-old), among them were 23 students and postgraduate. Instrumental research methods were used to record indices of functional fitness (FF) and physical work capacity of wrestlers while performing a specialized test with throws of a partner and a block of testing physical loads on a bicycle ergometer. Results. It was revealed that among factors determining the structure of wrestlers' fitness, the integral factor of FF general level (31.13% of the total variance) has the greatest impact on the variability of physical work capacity indices of athletes. Increase in skill level of wrestlers is associated with decreased time of performing throws in a specialized test, increased relative values of lactate power, O2-debt, general level of FF, O2 consumption per 1 kg of body mass. Improvement of wrestler FF structure along with an increase in their skill level is characterized by higher contribution of FF integral parameters (anaerobic power, mobility of physiological reactions, FF general level) to the manifestation of physical work capacity. It was revealed that the general level of FF of wrestlers is characterized by the following ratio of key factors (relative to model values of elite athletes): anaerobic power - 52.6 ± 4.9%, aerobic power - 52.8 ± 4,1%, mobility - 80.4 ± 5.3%, economy - 43.3 ± 3.0%. In the course of studies, mathematical models of the key factors of wrestler FF structure associations with the level of special work capacity, skill level and weight category have been developed. Modeling allowed to specify the criteria and develop scales for assessing special physical work capacity level, differentiated according to skill level and weight category groups of highly skilled wrestlers. Conclusions. The findings reflect the crucial role of anaerobic energy supply mechanisms in the manifestation of high special work capacity in wrestling. Improvement of wrestler FF structure along with the increase of their skills is characterized by a decrease in the number of key functional parameters determining the level of physical work capacity during testing with loads that model specific activity of highly skilled wrestlers. This, along with body functions economization, is one of the important criteria for improving FF structure of the combat athletes.

Seasonal evaluation of skeletal muscle damage and hematological and biochemical parameters of Greco-Roman wrestlers from the Kyrgyzstan National Team before the 2016 Summer Olympic Games.

Regular exercise activities affect blood cells. The purpose of this study was to evaluate the seasonal evaluation of some hematological and biochemical parameters of the Olympic Greco-Roman wrestlers. A total of three measurements were performed on wrestlers: immediately before the training period, three months and six months after the training session. Hematological and biochemical parameters were analyzed by taking sufficient blood samples from the athletes before and after exercise. The total leukocyte, lymphocyte, and neutrophil values were found to be significantly higher (p< 0.05) in all three measures (beginning, 3rd and 6th months) in comparison with the values before exercise. When biochemical analyses were examined, blood glucose levels were significantly decreased after exercise in all three measures compared to before exercise. Post-exercise HDL cholesterol concentrations significantly increased (p< 0.05) while LDL cholesterol concentrations significantly decreased (p< 0.05). On all three measures fatigue exercise has significantly increased the total leukocyte, lymphocyte and neutrophil values of wrestlers, while other, hematological parameters were not affected evenly. Fatigue exercise also significantly reduced blood glucose levels and LDL cholesterol concentrations, while HDL cholesterol concentrations were increased. The six-month period training did not have a significant effect on both hematologic and biochemical parameters in all three measurements.

The effect of a 4-week core strengthening program on determinants of wrestling performance in junior Greco-Roman wrestlers: A randomized controlled trial.

Core-strength is vital for Greco-Roman wrestling, although studies have yet to establish the effectives of core-specific training in this sport. To examine the effect of core-specific strength training on determinants of Greco-Roman wrestling performance in elite junior athletes. Twenty state-level, junior, Greco-Roman wrestlers were randomized into a core-specific training group (COR; n= 12) and a control group (CON; n= 8). The COR group undertook a 4-week, core-specific training program concurrently with their typical training program, whilst the CON group completed 4 weeks of typical training only. Both groups completed overhead medicine ball throw (OMBT), Suplexes, bridges and medicine ball chest throw (MBCT) prior to and following the intervention. The COR group demonstrated significantly greater improvement in bridges (p= 0.037; F= 5.046) and OMBT (p< 0.001; F= 26.43) than the CON group, with moderate to large between-group effect sizes (ES = 0.79-2.35). In addition, the effect size calculations were moderate-to-large (0.79-0.87) for Suplex and MBCT, with measures for the COR group greater than the CON group. Accordingly, core-specific training programs should be combined with wrestling-specific conditioning programs to improve back and hip extensor performance in junior Greco-Roman wrestlers.
