“…Accordingly, training programs should aim to develop both the upper and lower limb muscle force of boxers. Loturco et al ( 2019 ) recently confirmed the beneficial effects of a short-term power-oriented training program of lower limbs on performance of elite boxers. In the latter study, only three resistance training sessions including bench press, half-squat and jump squat exercises increased punching (jab and cross) impact forces by ~8%, and with an effective transference of ~0.80.…”

“…In our study the mean punch velocity, including all punch types was 9.8 ± 2.3 and 8.1 ± 1.2 m.s −1 in Elite and Juniors, respectively, which is in line with values reported in the literature for boxing, karate and kung-fu (Wilk et al, 1983 ; Neto et al, 2007 ; Lenetsky et al, 2013 ). In addition, the higher punching force and velocity in Elite compared to Juniors might be explained by a greater contribution from the legs to the punch (Filimonov et al, 1985 ) and/or a higher force production capability of lower body segments (Loturco et al, 2016 , 2019 ).…”

Punching in boxing requires a combination of force and velocity of the acting arm, originating from an optimal synchronization of the different body segments. However, it is not well-understood what kinematic parameters of the punching execution influence boxing performance the most. This study aimed to investigate the differences in punching execution between 15 potential Olympic medalist boxers (Elite group) and 8 younger well trained boxers (Junior group). Each athlete was equipped with an instrumented suit composed of 17 inertial measurement units (IMU) and were asked to perform several series of 3 standardized punch types (cross, hook, and uppercut) with maximal force. Linear velocity, stability, and punch forces were computed from the different sensors. Our findings show that Elite boxers systematically produced more force and at a higher velocity for the three punch types compared to Juniors. Further analysis revealed differences in joint contributions between Elite and Juniors, Juniors presenting a higher contribution of the shoulder for the three punch types. Finally ground reaction force imbalance between the front and rear foot was revealed in the cross only, in all boxers (60.6 ± 24.9 vs. 39.4 ± 24.9% and 54.1 ± 7.1 vs. 45.9 ± 7.1%, p ≤ 0.05, for the front vs. rear foot in Elite and Juniors, respectively) but not different between groups. These results have important implications for practitioners involved in the talent identification process, longitudinal follow-up, and training of boxers.

“…This opens new opportunities for using preparation strategies able to improve performance in the 1–12 h prior to competition (i.e., priming exercises) or even immediately before the combats (i.e., by applying modified warm-up practices including post-activation potentiation techniques) [ 32 , 33 ]. Another possibility could be the utilization of short-term low-volume training schemes throughout longer tournaments (i.e., 2–3 weeks), which have already been shown to produce significant increases in punching impact [ 23 ]. As boxers seem to not be affected by neuromuscular fatigue after matches and on subsequent days, coaches may consider incorporating these activities over the course of amateur boxing championships, with the goal of optimizing strength–power capabilities.…”

“…In the HS, athletes executed knee flexion until the thigh was parallel to the ground, and, after the command to start, subjects were instructed to move the bar as fast as possible, without losing foot contact with the ground, keeping their heels on the floor. In both exercises, a load of 5% BM for the BP and 10% BM for the HS was progressively added for each set until a clear decrement (at least 5%) in mean propulsive power (MPP) was observed [ 21 , 22 , 23 ]. A 5 min rest period was allowed between sets.…”

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.

“…Moreover, increased jump height and power appear to have a meaningful transfer to certain martial art movements. For instance, Loturco, Pereira, Kobal, Fernandes, Reis, Romano, Alves, Freitas, McGuigan 12 , indicated that short-term optimum COVID-19 Lockdown Effects on Vertical Jump Performance Page | power load training increased vertical jump power output by 12% with an accompanying 8% gain in punch power in elite boxing athletes. Moreover, authors noted an effective transference effect (TEC = 0.80) of jumping performance improvements to punching impact force, indicating that increases in lowerlimb power can be directly transferred to punching impact.…”

The COVID-19 pandemic has caused mandatory lockdowns leading to disruptions in sports training programs. This study aimed to determine the effects of a 16-week COVID-19 lockdown on body composition as well as kinetic and kinematic parameters of the countermovement jump (CMJ) for professional martial artists. Thirteen (n=13) professional martial artists participated in this retrospective cohort study. Subjects were tested on the CMJ at four timepoints: 1) pre-lockdown (pre), 2) immediately post-lockdown (post), 3) two weeks post-lockdown (post+2), and 4) four weeks post-lockdown (post+4). Body composition was measured via bioelectrical impedance and jump data were collected using a force platform sampling at 1,000 Hz. Individual repeated-measures ANOVAs were conducted with pairwise post-hoc analyzes. Differences were observed in vertical jump height (VJH) of 10.33%, peak velocity (PV) of 3.10%, reactive strength index modified (RSImod) of 13.8%, and peak propulsive power (PPP) of 6.00% (p<0.05). There as an increase from post to post+2 of 13.06% in VJ, 4.12% for PV, 14.0% for RSImod, and PPP of 4.66%. There was an increase from post to post+2 of 10.8% in VJH, 3.1% for PV, 14.0% for RSImod, and PPP of 3.0%. Fat mass (FM) and BF% increased from pre to post by 13% and 11%, respectively, and decreased 8% and 11% from post to post+4 respectively (p<0.05). In contrast, there was an decrease in fat-free mass (FFM) from pre to post of 11% and a decrease of 8% from post to post+4. There were moderate associations between FFM and VJH (rmc=0.47), FMM and PPP (rmc=0.47), FFM and PV (rmc=0.47), BF% and PV (rmc=-0.42), and FM and PV (rmc=0.42). While the lockdown resulted in a significant decrease in CMJ performance and increases in BF and FM, subjects’ performance returned to pre-lockdown levels after only 2-4 weeks of post-lockdown training by decreasing BF, FM, and increasing FFM.
