“…At the same time, mechanoreceptors will also undergo morphological changes, including irregular edges and flat structures. Scholars [ 5 ] have confirmed that the number of mechanoreceptors is positively correlated with the level of proprioception in the knee joint. Ruas et al [ 5 ] pointed out in the study of muscle response to external force that a certain amount of exudation will affect the sensory afferents of the knee joint, thereby inhibiting the neuromuscular response.…”

Objective. The knee ligaments, as a passive knee joint stability device, provide protection for the knee joint and ensure its functional integrity. This role has long been known and recognized by people. The original purpose of knee ligament reconstruction after knee ligament injury is to restore its anatomical structure and mechanical stability mechanism. Methods. Taking athletes as the research object, randomized controlled trials (RCTs) on improving ankle joint function of athletes related to proprioception training at home and abroad were included. The search time was from the establishment of the database to December 31, 2019, and the references of related documents were traced. Two researchers independently screened the literature, extracted data, and evaluated the quality of the literature. RevMan 5.3 software was used for data analysis. Results. The extensor strength, flexor strength, and flexor strength/extensor strength of the affected limb were higher than before the operation one year after surgery ( P < 0.01 ). The Lysholm score, Lysholm instability score, and one-foot jump distance were all higher than those before surgery ( P < 0.05 ); the difference of KT-2000 for both knees was smaller than that before surgery ( P < 0.05 ). Conclusion. In maintaining the anterior stability of the knee joint, the knee ligament provides 85% static resistance to prevent the tibia from moving forward, so knee ligament injury will cause knee instability. The proprioceptive feedback mechanism plays an important role in maintaining the functional stability of joints.

“…To maximize running and jumping performance, a correspondingly high peak torque value of the knee joint extensors is required [ 69 ]. The positive relationship between the H/Q ratio and 30 m sprint time may suggest the important role of knee joint extensors in sprint performance.…”

The correct torque ratio between the knee joint extensor and flexor muscle groups can effectively prevent injuries to the anterior cruciate ligament and hamstring strain. However, it is unclear whether a high torque ratio of the knee joint flexor muscles to the extensor muscles is beneficial for sport performance. Therefore, the aim of the study was to investigate the relationship between the hamstring-to-quadriceps (H/Q) ratio and sprint times (10- and 30-m) and jump heights (CMJ—countermovement jump and SJ—squat jump) in soccer players. The study examined 26 young elite soccer players (age: 18.1 ± 0.7 years; body height: 1.77 ± 0.05 m; body mass: 72.7 ± 5.7 kg). Knee joint flexor and extensor peak torques were assessed using the Cybex dynamometer (at 60°/s, 120°/s and 180°/s). Additionally, each participant performed the CMJ, SJ, and 30 m sprint. A significant relationship was obtained between the H/Q ratio (60°/s) and 30 m sprint time (r = 0.47). The positive direction of this relationship may indicate an important role of knee joint extensors in sprinting performance. Moreover, the H/Q ratio was not significantly associated with the CMJ, SJ or 10 m sprint performance. The H/Q ratio should be considered together with the peak torque values in terms of the assessment of sprinting and jumping performance.

“…Greater amounts of muscle activation seemed to be associated with phases of possibly superior quadriceps recruitment when compared to the hamstrings during a FW bout [38], suggesting quadriceps soreness was expected to be greater than the hamstrings; however, this was not the result. A variety of factors may have led to these conclusions including: biomechanical alterations in stress and force transference [3], differences within anterior-posterior propulsion and braking forces [3], or disparities in hamstringsto-quadriceps strength ratios [38,44]. However, none of these adverse factors were actively measured during this study protocol.…”

Purpose The Farmer's Walk (FW) may supplement resistance training through functional tasks like lifting and carrying weight over various distances. Minimal information exists concerning the intramuscular responses resulting from FW performance, possibly impacting its application in exercise prescription. Therefore, the purpose of the study was to investigate Creatine Kinase (CK) and myoglobin (Mb) responses following the Farmers Walk Condition (FWC) compared to a control protocol (NWC). Methods Fifteen participants (Mean ± SEM; age: 21.6 ± 0.5 years; height: 172.5 ± 2.4 cm; body weight: 81.8 ± 4.0 kg) completed an initial session to measure body composition, lower body power, and strength. Participants then completed two counter-balanced exercise protocols consisting of a 20-m walk performed within 5 sets of 2 repetitions while either carrying weight (FWC; average wt: 85.15 ± 25.55 kg) or not (NWC) with collection of Visually Perceived Muscle Soreness (VPMS), Ratings of Perceived Exertion (RPE), and blood samples. VPMS, blood samples, and Countermovement Jump (CMJ) height were also collected during recovery from each exercise protocol with significance of P < 0.05. Results Significant differences were observed between exercise protocols performed including participant RPE (P < 0.01), CK (P = 0.01), and overall, upper body, and lower body VPMS (P < 0.05) post-FWC. No significant differences were noted for Mb or CMJ height. ConclusionTraining variables implemented during the FWC may have indirectly minimized muscle damage and neuromuscular inhibitions in performance. Although participants reported mild soreness, the negligible physiological damage suggests the FWC is a safe and appropriate functional movement exercise.
