“…The strength of the athletes' ankle dorsiflexors and plantar flexors in the experimental group increased significantly after isokinetic training. 7 In the control group, only the strength of the plantar flexors was significantly increased. The ankle joint of the supporting leg of the high jump is subjected to enormous forces.…”

Introduction: Vertical jump is inherent to the practice of high jump and demands great capacity of force generation and work of the knee muscles, especially the quadriceps muscle. Due to this demand, imbalances between the extensor and flexor knee muscles may be present, leading to an overload of the musculotendinous structures of the knee joint. Therefore, it is necessary to establish the characteristics of isokinetic muscle strength in the knee joint of these athletes. Objective: This study aimed to analyze the biomechanical properties of the knee flexor and extensor muscles in high jump athletes. Methods: Ten high jumpers volunteered for the experiment. They were divided into experimental and control groups. Both groups performed basic strength training. The experimental group added isokinetic knee muscle training based on this training. Statistical analyses were performed on the training data of the two groups of athletes using relevant mathematical statistics. Results: The high jump consists of four phases being respectively the approach run, the jump itself (impulsion, elevation, transposition), and the fall. The strength of the ankle joint dorsiflexion and plantar flexors was significantly increased in the experimental group of athletes. In contrast, the strength of the plantar flexors in the control group was significantly increased. Statistical differences were found between the two groups (P<0.05). Conclusion: The isokinetic knee joint strength training mode can improve the leg support strength of jumpers. This paper suggests that high jump athletes can further adopt this lower limb strength training method. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

“…Therefore, it is also important to take into account reliable and valid measurement tools such as the optojump system, force plates, photoelectric cells, and the My Jump 2 app. This equipment is used in the field as a common measuring tool for athletes, and basketball players in particular, and although we chose not to present it in this article, we recommend considering it as well [1,2,99,103,[109][110][111][112][113][114][115].…”

Basketball playing entails the repetitive performance of short intense actions using lower limb explosive power. As such, it is important to measure this capability in basketball players, especially among young players, and to optimize training programs and game plans. After presenting an in-depth understanding of the specific physiological requirements when playing basketball, as well as the type of movements required, the aim of this review is to better understand the importance of the physiological energy systems in basketball, to examine the contribution of each energy system and, accordingly, to heighten awareness of the importance and dominance of the alactic anaerobic physiological system in basketball for actions requiring high-level explosive power. This review of the literature depicts the horizontal and vertical physical movements and physiological requirements entailed in playing basketball and presents eight standardized anaerobic alactic measurement tools relevant to the game. As some of these tests suit a number of ball games, the findings of this review article are important for making the order of the elements unique to basketball as well as additional parameters to consider when testing basketball players. By reliably and validly testing the anaerobic alactic capabilities of basketball players, test results can be used for training purposes and for improving game outcomes. Despite the fact that much of the information in this review is familiar to coaches, highlighting the specific needs of basketball will help them choose the most suitable tools and also shed light on new directions for developing basketball-specific assessment tests.

“…The correlation coefficients were 0.629 (P<0.01) and 0.574 (P<0.05), respectively. 11 Therefore, it can be seen that the maximum explosive power generated in the kick-stretching stage is closely related to the ability of the athlete's take-off leg knee extensor muscles to yield and contract. Burst power is one of the main factors affecting jumping performance.…”

Introduction: Joint strength of the lower limbs plays a decisive role in the competitive ability of long jumpers. Special strength training based on science and targeted at the strength of the lower limb joints is an essential topic for long jumpers. Objective: To analyze isokinetic muscle strength characteristics of lower limb joints in long jumpers. Methods: Voluntary jumpers were submitted to isokinetic concentric contraction tests of the lower limbs and hip joints. We also analyzed the effect of strength training on lower limb joint injury. Results: The knee muscles of the athletes have reduced eccentric contractility. The ankle of the athlete has the most vulnerable joint to injuries in the sport. Conclusion: The explosive force and eccentric contractility of long jumpers’ lower limb extensor muscles have the most significant impact on joint thrust and extension speed. Athletes need muscle strength training to develop isokinetic muscle strength. This can effectively prevent injury to lower extremity joint movements. The research findings of this paper can provide a specific theoretical basis for formulating scientific training for long jumpers. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
