“…The torso is a body region frequently used in judo techniques. The strength development in the torso is associated with specific performance parameters in judo players [ 25 ]. Our findings indicate that fat accumulation in the trunk region has a negative impact on performance in the SJFT, as well as in the other evaluated tests (CMJ, SJ, FPU, and PPU).…”

This study investigated the associations between total and regional body composition with performance in the special judo fitness test (SJFT), as well as strength and power tests (countermovement vertical jump—CMJ, squat jump—SJ, plyometric push-up—PPU, and force push-up—FPU). Twenty-three high-level judo athletes participated in this study. Initially, they underwent dual-energy X-ray absorptiometry, after which they performed the CMJ, SJ, PPU, and FPU tests. On another day, the SJFT was carried out. Correlations were tested using Pearson’s test. The performance in the SJFT was correlated with the total and arm %fat mass (r = −0.759), torso fat mass (r = −0.802), torso %fat mass (r = −0.822) and in the lower limb regions with the leg fat mass (r = −0.803) and leg %fat (r = −0.745). In the strength and power tests, there were also negative correlations observed between regional fat and performance. There was a negative correlation between the percentage of total fat and performance in the SJFT (r = −0.824), SJ (r = −0.750), CMJ (r = −0.742), PPU (r = −0.609), and FPU (r = −0.736). Fat, both total fat and regional fat in the arms, torso, and legs, is strongly correlated with a poor performance in the SJFT and poor strength and power.

“…The relationship between maximal force and rate of force production on judo performance has been widely investigated, providing evidence that the development of these physical attributes may transfer to judo techniques (e.g., throwing: harai-goshi [hip], sasaetsurikomi-ashi [foot], and morote-seoi-nage [shoulder]). For example, research addressing the relationship between trunk muscle strength and judo-specific pulling performances in judokas using a specially designed system mimicking the judo technique morote-seoi-nage showed that the trunk flexors accounted for 69% of the mechanical work, therefore advising judokas to develop trunk muscle strength to support dynamic pulling movements (28). Reducing the number and severity of injuries sustained by judoka and accelerating return to competition from injury is of interest given the high prevalence of injuries in judo, particularly in areas exposed to more significant stress and impacts during specific techniques and combat (4,33,54).…”

Weldon, A, Cloak, R, Kirk, C, Ruddock, A, Langan-Evans, C, Detanico, D, Loturco, I, and Kons, R. Strength and conditioning (S&C) practices of judo athletes and S&C coaches: A survey-based investigation. J Strength Cond Res 38(4): e160–e173, 2024—The benefits of strength and conditioning (S&C) for improving judo performance and reducing injuries have been widely studied. However, the S&C practices used and perspectives held by those delivering S&C have yet to be elucidated. Therefore, this study investigated the S&C practices and perspectives of judokas and S&C coaches working within judo. Forty-two judokas and 9 S&C coaches completed an online survey comprising 6 sections: (a) written informed consent; (b) background information; (c) education, qualifications, and prescription; (d) views on S&C; (e) exercise selection; and (f) issues and improvements. Frequency analysis was used to report responses to fixed-response questions and thematic analysis for open-ended questions. Results indicated that S&C coaches were primarily responsible for delivering S&C programs (60%), and S&C information was predominantly sourced from S&C coaches (43%). Strength and conditioning was deemed very important for randori (78–88%), overall judo performance (67–79%), and judo fitness (62–78%). Similarly, S&C was considered very important for the development of speed and power (76–89%), strength (71–89%), and injury reduction (69–78%). Novel findings were also observed, such as integrating judo-specific training within S&C practice, which may be partly explained by more S&C coaches holding judo belts (67%) than S&C qualifications (11%). This study supports practitioners delivering S&C in judo by offering a base of information to critique or align with their existing S&C practices and perspectives. Furthermore, our results may help identify potential gaps between methods used, proposed guidelines, and actual practice, facilitating the development of research and education resources tailored to the current climate.
