“…This ratio plays a decisive role in the stability of the knee joint, reflecting the muscular balance between the extensors and flexors and in our study the results obtained are similar to those of Lira et al [32] in which the average values of H/Q ratio (%) in both limbs and at all competitive levels indicate a high probability of injury, since according to Aagaard et al [35], values below 60%, as was our case, increase the susceptibility to injury. Also Ferreira et al [17] suggest that injury prevention strategies should focus on the normative value of 60% at an angular velocity of 60°/s (as was our case). Croisier et al [34] indicated that muscle strength imbalances put a player at an average 4.6 times greater risk of developing hamstring injuries, so our results alert us to this possibility in the players assessed.…”

. (1) Background: The aim of this study was to verify the differences in body composition, power and lower limb muscle strength in futsal players from three competitive levels. (2) Methods: The study involved 68 players (24.26 ± 4.63 years), divided into three competitive levels: elite, sub-elite and amateur. To assess physical condition, we used the Inbody270, the ChronoJump and the Isokinetic Dynamometer and used the non-parametric Kruskal-Wallis test to compare the three independent variables. (3) Results: There were no differences in body composition between the players at the three competitive levels. With regard to lower limb muscle power and strength, the elite group showed, on average, better performance and capabilities, especially when compared to the amateur group, and all groups showed an H/Q ratio &gt; 60%. (4) Conclusions: We conclude that there are not many differences in physical condition between the three competitive levels of futsal, despite the unequal sporting demands between them. However, the elite group has greater power and muscle strength, and both groups showed a high probability of lower limb muscle injury at this stage of the sporting season, alerting sports training professionals to the importance of individualized analysis of physical condition and performance capacity.

“…Furthermore, studies indicate that an imbalance in the H/Q ratio correlates with a higher incidence of lower limb injuries [40]. According to some authors, values below 60 % increase the likelihood of injury [26,41].…”

“…Additionally, it is during the preseason period that sports and health professionals focus on developing players' physical condition in order to prepare them for the various demands of the competitive period [22]. It is also at this stage, especially at the beginning of the sport season, that the clinical department of each club should provide a detailed and rigorous assessment of the players' physical condition, including the evaluation of body composition, lower limb power and muscle strength, with the aim of characterizing the general state of health as well as identifying the players' individual needs in terms of potentially modifiable injury risk factors [23][24][25][26]. In this way, it is possible to anticipate the probability of injury during the competitive season, implementing preventive and individualized training programs [24] aimed above all at optimizing performance and minimizing the risk of injury [11,23,27].…”

Although there are some studies that have linked fitness parameters and sports injuries, the literature remains controversial. The aim of the study was to prospectively analyze the influence of initial physical condition parameters on the development of injury in the first three months of the sports season in futsal players. A total of 68 players (24.26 ± 4.63 years old) were assessed before the start of the sport season in relation to certain physical condition parameters, such as body composition (bioimpedance), lower limb power (countermovement jump, CMJ) and muscle strength (isokinetic dynamometer). The injured players showed significantly worse initial performance in the CMJ compared to the uninjured players (p < 0.001). There were no significant differences between groups in body composition and muscle strength. Lower power values were associated with a higher risk of injury in the first few months of the sport season (OR = 0.92; 95% CI = 0.88 - 0.99). Muscle power was an independent predictor of injury in the first few months of the sports season in futsal players, indicating that improving players' physical condition could help reduce the number of injuries.

Background: The aim was to verify the differences in physical condition (body composition, power and muscle strength) in futsal players from three competitive levels. Methods: Sixty-eight (24.26 ± 4.63 years) Portuguese futsal players participated in the study, divided into: elite, sub-elite and amateur. We used the Inbody270, the counter movement jump and the isokinetic dynamometer to assess physical condition, and the Kruskal-Wallis test to compare variables between groups. Results: There were no differences in body composition between groups. Elite players had higher countermovement jump heights than amateur players (p < 0.001). There were significant differences in the isokinetic muscle strength of the knee flexors, with the elite players showing more strength than the amateur players (p = 0.047). Conclusions: The elite players had higher physical condition parameters (more lower limb power and more flexor muscle strength) compared to the amateur players. We would point out that all groups had a high probability of lower limb muscle injury (H/Q ratio < 60%) at this stage of the sports season, alerting training professionals to the importance of individualised physical condition analysis.
