Predictors of Judo-Specific Tasks From Neuromuscular Performance in Young Athletes Aged 11–16 Years

The relationship between judo specific test performances and physical fitness in prepubescent male judo athletes

“…However, it is surprising that no correlation was found between peak anaerobic power and SJFT performance contrary to our expectation. Significant correlations have been reported between SJFT performances and aerobic, anaerobic power and other performance tests in the studies conducted on adult and child/young judo athletes (Franchini et al, 2007;Franchini, Sterkowicz, et al, 2011;Garbouj et al, 2016;Hesari et al, 2014;Kons et al, 2020;Sterkowicz et al, 1999). Garbouj et al (2016) reported significant correlation between maximum oxygen consumption and SJFT performance and aerobic power was effective during both the test and recovery.…”

“…With variables obtained from SJFT, positive significant correlations were found between number of throws and anaerobic capacity, maximum oxygen consumption and muscle strength and negative significant correlation was found between the SJFT index and the mentioned variables (Franchini et al, 2007;Franchini, Sterkowicz, et al, 2011;Hesari et al, 2014;Sterkowicz et al, 1999). Moreover, a study stated a relationship between strength and power test performances and SJFT performance in young judo athletes (Kons et al, 2020). Casals et al (2016) conducted a study to cadet judo athletes and stated significant correlations between body mass, biceps skinfold thickness values and somatotype characteristics of the athletes and SJFT performance indices.…”

“…Many studies regarding judo specific tests whose validity and reliability were already proven with laboratory tests focus mainly on elite and adult judo athletes (Ceylan et al, 2022;Chaabene et al, 2018;Franchini et al, 2007;Garbouj et al, 2016;Sterkowicz et al, 1999). Also, the number of studies related to the relationship between fitness tests and judo specific tests in the young judo athletes is very limited (Agostinho et al, 2018;Fukuda et al, 2013;Kons et al, 2020). Moreover, there are complicated relationships among body size, biological maturity, strength, and motor fitness in children unlike adults (Katzmarzyk et al, 1997).…”

“…In this way, they can be used to monitor performance of pre-and pubescent judo athletes. Kons et al (2020) examined the relationship between SJFT and judogi grip strength tests with only neuromuscular tests in young judo atheletes (11-16 years) and stated that neuromuscular tests can moderately predict SJFT performance. In current study, apart from neuromuscular tests, other components of physical performance such as cardiovascular fitness, agility and body composition were also included.…”

Strength and Conditioning (S&C) Practices of Judo Athletes and S&C Coaches: A Survey-Based Investigation

“…Accordingly, using S&C (general preparation) and randori (specific preparation), judo-specific fitness can be enhanced, which has been shown to underpin the execution of judo techniques and high-intensity grip disputes (32,34) and be a discriminating factor between competitive standards (e.g., national vs. regional) (18). For example, performance in neuromuscular tests (i.e., standing long jump, seated medicine ball throw, and handgrip strength) was moderately correlated with the Special Judo Fitness Test (SJFT) and Judogi Grip Strength Test (JGST) (37). Other research using the SJFT reported that judokas with superior performance were significantly correlated with higher anaerobic thresholds, lower blood lactate accumulation, and power production (14).…”
