BACKGROUND: Data about lower extremities’ strength and power asymmetries in fencers, and their relationships to fencing performance are limited and inconsistent. OBJECTIVE: The aim of the present study was to investigate asymmetries, between dominant (D) and non-dom (ND) legs of elite young male and female fencers, in relation to performance in fencing specific tests. METHODS: Anthropometric characteristics, unilateral vertical-horizontal jumping, isokinetic strength, lunge and step lunge performances were evaluated in 16 male and 22 female elite fencers. RESULTS: Significant differences between genders were found for all anthropometric measurements (p< 0.05). No significant bilateral asymmetries and gender x laterality effects were observed (p> 0.05). Fencing performance was negatively correlated with the D leg’s flexion/extension (F/E) ratio at 300∘/s (r: -0.564 to -0.619, p< 0.05). In addition, D leg’s F/E ratio at 300∘/s was positively related to lung peak velocity and power in female fencers (r: 0.562–0.649; p< 0.05). Finally, only in female fencers, unilateral triple hop distance was significantly related to lung peak velocity and power (r: 0.442–0.500; p< 0.05). CONCLUSIONS: The results of the present study suggest that the differential activation/movement pattern of the D and ND leg muscles do not lead to anatomical, dynamic and functional lower extremities asymmetries.

Kontochristopoulos, N, Bogdanis, GC, Paradisis, G, and Tsolakis, C. Effect of a supplementary periodized complex strength training and tapering period on postactivation potentiation of sport-specific explosive performance in adolescent national-level fencers. J Strength Cond Res 35(6): 1662–1670, 2021—This study examined the effects of strength training and tapering on countermovement jump (CMJ), change of direction (COD), and step-lunge (SL) after a conditioning activity in adolescent fencers. Twenty fencers (age: 15.8 ± 1.2 years) were randomly assigned to experimental (EXP, n = 10) group and control (CON, n = 10) group. EXP and CON groups performed 8 weeks of fencing training (4 times per week), while EXP group performed a supplementary strength training program twice per week, including a hypertrophy (first 2 weeks) and a complex strength training period (6 weeks). A 14-day tapering period with reduced training volume was then applied in both groups. Conditioning activity consisted of 3 × 3 seconds of maximal voluntary isometric contraction (MVIC; half-squat; knee angle = 90°), followed by either CMJ or COD or SL performance measurements in 3 different testing sessions 24 hours apart. There was no performance enhancement in all tests for both EXP and CON groups, after the conditioning MVIC before training (p > 0.05). After training, half-squat dynamic strength (1 repetition maximum [1RM]) was significantly increased only in the EXP group (from 74.8 ± 20.0 to 127.0 ± 28.9 kg, p = 0.001) and maintained after tapering. After tapering, baseline CMJ height was significantly increased only in the EXP group (from 27.2 ± 4.6 to 30.9 ± 3.8 cm, p = 0.003). Contrary to our hypothesis, the increase in 1RM and CMJ was not followed by a postactivation potentiation enhancement in all tests (p > 0.05), possibly because of the relatively low strength and jumping performance of fencers. Thus, adolescent high-level fencers do not exhibit a performance increase after MVIC, and this was not modified by the supplementary strength training protocol used.

Fencing is a combat sport, where beyond physical and physiological demands, strategy and tactics are crucial factors in order to identify fencers' performance. Fencers' tactical movements can be separated in preparatory actions and final actual offensive (attacks) and defensive (parries and counterattacks) actions. The aim of this study is to analyse the tactical choices of elite male and female qualifiers foil fencers in finals and semi-finals bouts of the 2016-17 FIE (International Fencing Federation) competitions. Attacking and defending points were recorded, compared with the type of point, the section thrusts were landed and the time period they were noted. The present study revealed significant difference between offensive and defensive efficacy in both male (p < .003) and female fencers (p = .019). Male fencers showed greater activation than women (p = .003), finishing their bouts much earlier (p = .000), since they needed less time to accomplish an actual action (p = .001). In conclusion, male could be characterized as ''permanently pressing'' fencers, while female adopted a ''manoeuvring-attacking'' style, since male fencers had greater percentage of total actions on the middle section of the piste (p = .011) and female fencers had greater number of defending actions on the back section (p = .033), respectively.
