The present study investigated the effect of an additional short-duration HIIT program using boxing-specific techniques on activity during a simulated competition. Additionally, we investigated the impact on physical fitness, specifically aerobic performance and lower-body muscle power. Sixteen boxers were randomized into a control (n = 8) or experimental groups (n = 8). The experimental protocol consisted of 3 blocks of 5 repetitions of 30s all-out effort, with 6s recovery between repetitions and 1 min rest interval between blocks, conducted 3 days per week for 4 weeks. A two-way (group, two levels; moment, two levels) analysis of variance with repeated measurements in the second factor was used. For the experimental group, there was a change in body mass (ES = −0.13 (trivial)), body fat percentage (ES = −0.12 (trivial)), VO2max (ES = +0.42 (small)), CMJ (ES = +0.12 (trivial)), CMJ-left (ES = −0.11 (trivial)), CMJ-right (ES = +0.22 (trivial)), actions (ES = +0.68 (moderate)), time (ES = −0.29 (small)) and punches (ES = +0.56 (moderate)). For the control group, there was a change in body mass (ES = +0.04 (trivial)), body fat percentage (ES = −0.12 (trivial)), VO2max (ES = +0.11 (trivial)), CMJ (ES = −0.27 (small)), CMJ-left (ES = −0.39 (small)), CMJ-right (ES = +0.08 (trivial)), actions (ES = +0.08 (trivial)), time (ES = −0.65 (moderate)) and punches (ES = −0.57 (moderate)). The punches variable was significant concerning group-by-time interaction (F1,14 = 11.630; p = 0.004; n2 = 0.454). The present study indicated that the addition of a boxing-specific HIIT program is effective to increase the number of punches during a simulated match.

This study aimed to describe self-selected intensity and its relationship to performance during a high-intensity all-out judo protocol, and to verify whether athletes with different anaerobic speed reserve (ASR) perform differently during a high-intensity all-out interval uchi-komi (judo-specific skill). We analyzed the performance of 28 judo athletes as a whole group and divided into groups, according to their ASR. They performed several judo-specific protocols using a specific skill: maximal speed sprint (MSS) and maximal aerobic speed (MAS), and high-intensity intermittent uchi-komi protocol (12 × 20 s all-out:10 s passive recovery). The main results demonstrated a decrease in the number of repetitions and an increase in heart rate across the sets. Athletes with greater ASR performed a higher number of repetitions, compared to the low ASR group, and they were able to exercise at a higher percentage of the MAS (low ASR = 126%; SD = 13%; high ASR = 152%, SD = l9%) and at a lower percentage of MSS compared to the low ASR group (low ASR = 84%, SD = 7%; high ASR = 76%, SD = 11%). However, both groups exercised at a similar percentage of their own ASR during the protocol (low ASR = 50%, SD = 20%; high ASR = 53%, SD = 19%). Athletes with different ASR seem to set their pace at around 50% of their ASR within an all-out uchi-komi protocol. Therefore, the ASR is useful for predicting performance during high-intensity judo-specific interval exercise intervals.

This study aimed to describe the frequency of video review (VR) used during international judo matches. The duration and time of VR occurrence and the effect of VR on subsequent referee’s decisions and match outcomes were investigated. Video recordings from the matches in which the VR was used in the 2020 Grand Slams (n = 122) were analysed. The main results showed most VR occurrences were from 1 to 2 min for female athletes (p = 0.03). Lightweight categories in both male and female groups showed the highest frequency of VR (37.3%). No significant differences were detected for VR duration and time when VR occurred considering sex and weight categories (p = 0.91, p = 0.26, respectively). A significant association was found between the type of action and the referee’s decision (p < 0.01), being score assignment the most frequent action (77.6% of male and 64.8% of female). More than 80% of the athletes (82.3% male and 78.3% female) won their matches after referees’ checking. We concluded that VR is often used at the beginning of the match mainly in the female group, mostly concerning scoring attribution, which directly affected the match result in more than 80% of the cases.

The aim of this study was to examine changes in body mass (BM) and power-related measures in Olympic boxers during an official qualifying boxing tournament. Fourteen elite amateur boxers from the Brazilian National Team (eight men and six women) participated in this study. Athletes performed three fights in four days against the same opponent of the same weight-category. Before and immediately after every fight, BM, countermovement jump (CMJ) height, and power production in the bench-press and half-squat exercises were assessed in the same order and on the same time of the day. A two-way repeated-measures ANOVA with the Bonferroni post-hoc analysis was used to determine the variations between pre- and post-measures. The statistical significance was set as p < 0.05. The athletes were able to maintain their baseline weight and physical performance throughout the experimental period, as shown by the lack of significant changes in BM, CMJ height, and upper- and lower-limb power output. Throughout a four-day qualifying tournament, the BM and power-related performance of Olympic boxers were not affected either by match execution or by successive matches. As scoring actions are highly dependent on muscle power, it is likely that these combat athletes are able to maintain optimal levels of performance across consecutive matches.

This study aimed to examine the effect of intense intermittent lower-body and trunk exercise (rowing) on punching performance in 28 highly-trained male amateur boxers. Straight- and bent-arm punch performances were assessed with a custom-built punch integrator using a 3-min maximal-effort punch test, completed in both non-fatigued (ROWpre) and fatigued (ROWpost) states. A within-subject repeated measures design was implemented; subjects completed ROWpre, then 9 × 1-min bouts of rowing (1-min rest intervals), followed by ROWpost. Peak punch force and force-time variables, including impulse and rate of force development (RFD; calculated to five time points), were assessed. Differences between ROWpre and ROWpost for each punch type (jab, cross, lead- and rear-hand hook) were tested with a linear mixed model, and effect sizes (Cohen’s d) were calculated. Results showed significant (p < 0.05) reductions in punch force in ROWpost compared to ROWpre for all punch types as well as significant delays in the time to reach specific force levels, and relative percentages of peak force (RFD) in all punches except the jab. It is likely that fatigue of the lower body and trunk muscles impaired ground reaction force, and thus punch force, production. This effect was larger in punches that involved a greater degree of trunk rotation, crosses and hooks, than in the jab which relies predominantly on arm extension. These findings reveal the negative effect of fatigue on punch force production, and provide evidence that lower-body and trunk force are important for generating punch force.

This study aims to compare the effect of sprint distance and repetition number on performance, physiological responses, and energy systems contributions. Eighteen male university league soccer players (age: 19.9±1.6 years, height: 177.9±4.7 cm, body mass: 72.4±6.3 kg, percentage body fat: 8.9±1.8, training experience: 7.4±1.6 years) completed two different repeated sprint protocols: 20 × 20 m (20×20) and 10 × 40 m (10×40) with 15s and 30s rest intervals, respectively. Oxygen uptake (VO2) were measured during the rest, exercise, and recovery phases. Rest and peak blood lactate concentrations were determined. Using VO2 and lactate values, the energy system contributions were calculated using a mono-exponential model and mathematical calculations. Energy systems contributions and total energy expenditure (TEE) were calculated both for the entire protocol (overall) and for the sprints only. Ratings of perceived exertion (RPE), peak and mean heart rate (HR) responses were significantly higher in the 20×20 whereas lactate response was higher in the 10×40. TEE was similar between the 10×40 (586.3±60.8 kJ) and 20×20 (595.6±57.5 kJ). For overall estimations, the 10×40 and 20×20 presented similar results of oxidative (47.5±5.4 vs 45.7±5.1 kJ.min-1) and phosphagen (44.7±5.4 vs (42.9±4.8 kJ.min-1) systems contributions whereas glycolytic contribution was higher in the 10×40 (15.5±2.2 vs 12.8±2.3 kJ.min-1). For sprints only estimation, the phosphagen (257.6±31.5 vs 225.2±28.2 kJ.min-1), glycolytic (89.4±13.4 vs 67.3±12.5 kJ.min-1), and oxidative (76.9±6.9 vs 72.0±7.9 2 kJ.min-1) systems contributions were higher in the 10×40. Although HR and RPE responses were higher in the 20×20, phosphagen (during sprints) and glycolytic (during both sprints and overall protocol) were higher in the 10×40 protocol. Therefore, the 10×40 protocol seems more reasonable for developing or evaluating the anaerobic systems.

This chapter deals with historical aspects of strength training, contextualizing the relevance of strength training for combat sports to maximize the performance of grapplers, strikers, and mixed martial artists. Scientific articles were listed that presented data related to maximum strength in the leading research databases. Scientific evidence presented in official and simulated matches, and official competitions are presented. Likewise, longitudinal studies on the development of maximal strength in combat sports athletes, maximal strength tests for combat sports athletes (dynamic, isometric, and isokinetic tests), and reference for maximal strength (dynamic and isometric exercises) values in several exercises, as well as normative tables are presented. Another point approached was training prescription for muscle hypertrophy and maximal strength development (dynamic and isometric) for combat sports athletes.

In combat sports, the specificity of the training requires that the athlete improve all performance indicators associated with the match. For this reason, muscle power seems to be determinant during the application of the techniques that result in scores, specifically punches, kicks, elbows, knees, throwing techniques, transitions to the groundwork and some groundwork techniques and sometimes, the win match by knockout. Based in these information’s, the present chapter will approach items referring to the muscle power manifestation and monitoring, and to the training prescription of exercises for the grappling, striking and mixed combat sports.

The range of motion of a joint is extremely important in combat sports, especially when there is a need to execute a certain motor gesture with maximum range of movement, as in throwing techniques such as uchi-mata in judo, certain types of guards in Brazilian jiu-jitsu or the high kicks common in a variety of striking combat sports. Therefore, in this chapter, we will discuss the elements related to flexibility response during training sessions or combat sports competitions, flexibility tests commonly used for these athletes, and the monitoring and control of the evolution of flexibility in athletes. We will also present the means and methods used for the development of flexibility and longitudinal studies on the development of flexibility in combat sports athletes. Finally, this chapter supports based on the evidence the inclusion of flexibility development within training sessions is an important consideration to maximize performance and other physical capabilities that may be affected both acutely or in the long-term by flexibility.

Strength-endurance is one of the trainable physical capacities that could determine the success in some combat sports and its inclusion is obligatory in the training periodization of high-level athletes. In striking combat sports, such as boxing and taekwondo, it seems likely that increases in dynamic strength-endurance improve the ability to execute combat movements repeatedly. On the other hand, grapplers need to develop high levels of strength-endurance because during the match much time is spent in grip dispute and the success in this phase may determine the possibility to execute scoring techniques. Furthermore, in mixed combat sports, where a combination of striking and grappling are required, athletes needs to have the capacity to maintain dynamic or static muscular actions during prolonged periods during the match, and the strength-endurance is one key element. Therefore, this chapter presents the strength-endurance requirements during the match, the specific tests for its evaluation, scientific evidence of longitudinal studies on the development of strength-endurance in combat sports athletes and the methods for its development.

This chapter describes the physiological responses associated with aerobic power and capacity of combat sports athletes from different modalities (judo, Brazilian jiu-Jitsu, wrestling, Olympic boxing, taekwondo, karate and muay-thai) during specific and non-specific situations. Moreover, we describe the most used methods for the control and monitoring of these variables. Finally, the longitudinal studies that investigated the effects of aerobic power and capacity training for combat sports athletes are descripted.

The Judo World Ranking List has been used to assess its predictive power regarding athletic performance. The aim of this study was to check if the ranking difference among athletes in the individual rankings could be used as a predictor for the outcome of mixed teams judo competition. We sought to verify the association between the variable “rank difference” and the probability of the higher-ranked athlete winning against that lower-ranked. This heterogeneity between athletes is a major factor in increasing or decreasing the team’s chances of winning. The higher ranked athlete’s defeat seems to have a significant negative effect on his/her teammates in subsequent bouts. These findings imply that future studies on mixed teams judo competitions should consider individual ranking differences among athletes as a predictor of performance.

The aim of this study was to verify the effects of internal and external focus of attention, and a control condition on the performance, physiological and perceptive responses in a judo-specific all-out interval protocols. Fifteen male judo athletes participated in this study and performed two judo-specific protocols: maximal velocity anaerobic (MVAP) and high-intensity interval exercise (HIIE). The focus of attention instructions (internal and external) and control condition were randomized. Heart rate (HR), rating of perceived exertion (RPE) and felling scale (FS) were monitored during all tests and conditions. The main results demonstrated that the number of repetitions in MVAP did not differ between conditions (p = 0.434). For the number of repetitions in the HIIE across sets there were no effects of condition (p = 0.847), but an effect of sets was found (p < 0.001). No effects of condition were found for HR (p = 0.776), FS ( p 0.8) and RPE (p = 0.307), but an effect of sets was revealed for HR (p < 0.001) and FS (p < 0.001). It can be concluded that the manipulation of focus of attention did not affect the number of repetitions, HR, RPE and FS responses during an all-out judo-specific protocol.

The aim of this study was to analyze the impact of the social distancing recommendations during COVID-19 pandemic on the physical activity behavior in adults living in region of Northern Brazil. A final sample of 654 adults (386 women) aged 33 ± 10 years old participated in this study. A questionnaire with 45 questions concerning sociodemographic characteristics, self-perception of health and characteristics of physical activity behavior before and after the recommendations of social distancing was applied in an online format. Comparisons between levels of physical activity before and after pandemic were conducted applying a McNemar test. A binary logistic regression was applied to analyze the factors associated to being physically active during the pandemic. Analyzing the percentage levels of physical activity before and during social distancing, we observed an increase of physically inactive behavior (19% vs. 36.7%), as well as a decrease in active (32.6% vs. 18.6%) and very active (16.7% vs. 6.6%) behaviors, respectively. Among participants, 59.2% of them became sedentary during pandemic. Walking and running activities continued to be among the most practiced, although they showed a reduction during social distancing. Social distancing recommendations due to the COVID-19 pandemic caused decrease in the overall levels of physical activity in adults living in the Amazonas State and specifically in the practice of individuals who were physically active and very physically active before pandemic.

The main objective of the present study was to determine whether variation in gripping action, actions before attacking, throwing techniques, direction of attack, transition from standing to groundwork combat, and groundwork techniques varied between male and female judo athletes and between gold, silver and bronze medalists in judo World Championships for cadet, junior and senior athletes. Therefore, 296 athletes who won medals in these competitions between 2018 and 2019, who executed a total of 1202 scoring actions in standing position and 300 scoring actions in the groundwork combat were analyzed. Higher variation was observed for gold medal winners for grip, actions before attack compared to bronze medalists, whereas transition variation was greater for gold medal winners compared to the other medalists. However, no differences were found between age groups, except when interacting with sex, as a lower technique variation was observed in female cadets compared to all other male age groups. Additionally, less variation was observed in females compared to males for grip, actions before attacking, number of techniques and direction of attacks. Therefore, variation in some elements can properly discriminate the podium position, females present less variation than males, but no relevant differences were found between age groups.

This study investigated the relationship between well-being indices and the session rating of perceived exertion (session-RPE), recovery (TQR), and physical enjoyment (PE) during intensified, tapering phases of judo training. Sixty-one judo athletes (37 males, ranges 14–17 years, 159–172 cm, 51–67 kg) were randomly assigned to three experimental (i.e., randori, uchi-komi, running) and control groups (regular training). Experimental groups trained four times per week for 4 weeks of intensified training followed by 12 days of tapering. Session-RPE, well-being indices (i.e., sleep, stress, fatigue, delayed onset of muscle soreness (DOMS), Hooper index (HI)), and TQR were measured every session, whereas PE was recorded after intensified, tapering periods. Recovery (TQR) was negatively correlated with sleep, stress, fatigue, DOMS, HI, session-RPE in intensified period and was negatively correlated with sleep, stress, fatigue, DOMS, HI in tapering. Session-RPE was positively correlated with sleep, fatigue, DOMS, HI in intensified period and positively correlated with fatigue, DOMS in tapering. PE was negatively correlated with stress in intensified training. Enjoyment could be partially predicted by sleep only in intensified periods. Session-RPE could be partially predicted by TQR, fatigue during intensified periods and by sleep, and HI during tapering. Sleep, recovery state, pre-fatigue states, and HI are signals contributing to the enjoyment and internal intensity variability during training. Coaches can use these simple tools to monitor judo training.

The present systematic review examined the effect of exercise intensity (high‐intensity interval exercise [HIIE] vs. moderate‐intensity continuous exercise [MICE] vs. sprint interval exercise [SIE]) on excess post‐exercise oxygen consumption (EPOC). Twenty‐two studies were included in the final evaluation. The retrieved investigations were split into studies that analysed short‐duration (until 3 h) and long‐duration (more than 3 h) EPOC. Studies that subtracted the baseline energy expenditure (EE) were analysed separately from those that did not. Most short‐duration evaluations that subtracted baseline EE reported higher EPOC for HIIE (average of ~136 kJ) compared with MICE (average of ~101 kJ) and higher values for SIE (average of ~241 kJ) compared with MICE (average of ~151 kJ). The long‐duration evaluations resulted in greater EPOC for HIIE (average of ~289 kJ) compared with MICE (average of ~159 kJ), while no studies comparing SIE versus MICE provided appropriate values. EE from EPOC seems to be greater following HIIE and SIE compared with MICE, and long‐duration evaluations seem to present higher values than short‐duration evaluations. Additionally, more standardized methodologies are needed in order to determine the effective EPOC time following these protocols.

This study investigated the effects of 4-weeks repeated sprint (RST) vs. repeated high-intensity-technique training (RTT) on physical performance. Thirty-six adolescent taekwondo athletes (age: 16 ± 1 yrs) were randomly assigned to RST (10 × 35 m sprint, 10 s rest), RTT (10 × 6 s Bandal-tchagui, 10 s rest) and control (control group (CG): no additional training) groups. Additionally, to their regular training, RST and RTT trained 2×/week for 4 weeks. Training load (TL), monotony, and strain were calculated using the rating of perceived exertion scale. The progressive specific taekwondo (PSTT), 20 m multistage shuttle run (SRT20m), 5 m shuttle run, agility T-test, taekwondo-specific agility (TSAT) and countermovement jump (CMJ) tests were performed before and after 4 weeks of training. Additionally, taekwondo athletes performed specific taekwondo exercises (i.e., repeated techniques for 10 s and 1 min). From week 1, mean TL increased continuously to week 4 and monotony and strain were higher at weeks 3 and 4 (p < 0.001). VO2max calculated from SRT20m and PSTT increased for RST and RTT in comparison to CG (p < 0.001). Agility performance during T-test and TSAT (p < 0.01) improved in RTT. The number of performed techniques during the 10 s specific exercise increased in RTT and RST (p < 0.01) for the dominant leg and in RTT for the non-dominant leg (p < 0.01). The number of techniques during the 1 min specific exercise was higher in RST and RTT compared to CG for the dominant leg (p < 0.001). Delta lactate at post-training was lower for RTT for both legs compared to RST and CG (p < 0.01). It is important to include a low-volume high-intensity training based on repeated sprint running or repeated technique in the training programs of adolescent taekwondo athletes.

We quantified the peak age of judokas during the World Championships (WC) and Olympic Games (OG) according to sex, weight category and competitive achievement and determined the relationship between competition year and athlete age. A retrospective study including 12,005 athletes who took part in the last 16 WC and 6 OG. Athletes were divided by sex, weight category and competitive achievement. Overall, females were younger than males, and older athletes competed at the OG compared to the WC. A weight category effect was also observed, with lighter athletes being younger than heavier athletes (p < 0.05). A competitive achievement effect was found for females, with athletes being defeated in the eliminatory phases being younger than those advancing further in the competitions (p < 0.05). Significant associations (p < 0.05) were shown between competition year and age category for males at the WC and for females at both the WC and OG. In general, lighter athletes are younger than heavier ones (p < 0.05). No difference in age was found between males concerning their competitive achievement in WC and OG, whereas younger females are defeated in the eliminatory phases (p < 0.05).
