“…Exercises in closed kinematic chains act completely on the entire kinematic chain, more evenly distribute the load on all links of the chain [24,25]. The program also involved a conscious focus on the inclusion of all muscles of the closed kinematic chain in the process of performing each movement.…”

Background and Study Aim. Students are often injured while playing sports. The main condition for preventing injuries is the correct technique of movements. In the literature, rock climbing has not been analyzed in terms of prevention of student injuries. Therefore, the development of programs to prevent injuries of students-rock climbers is relevant. Aim: to determine the impact of the use of exercises in a closed kinematic chain on the technical skill and the number of injuries to the elbows of student-rock climbers based on the analysis of the one-arm hang technique. Material and methods. First, to substantiate the correct technique in rock climbing, the technique of performing one-arm hang was analyzed by 20 leading male climbers of Ukraine and 20 students - novice male climbers. Then a randomized control study was conducted. The participants in the randomized control study were 40 male students-climbers in the intervention group and 44 male students-climbers in the control group aged 18-19 years. The one-arm hang technique was determined based on the angles between the shoulder and the collarbone during the movement. The experiment lasted 1 year. At the beginning and at the end of the experiment, the analysis of the one-arm hang technique was carried out. The number of elbow injuries in both groups was also recorded. Results. The main parameters of the one-arm hang technique for qualified and unskilled climbers have been substantiated. For qualified climbers, one-arm hang involves the muscles of the shoulder girdle, torso, and legs. In unskilled climbers, one-arm hang is provided only by the muscles of the arm. In a control randomized study, there was a significant improvement in the results of biomechanical analysis of the hang technique in athletes in the intervention group (p <0.001). The use of exercises in a closed kinematic chain significantly reduces the incidence rate of elbow injuries in student-climbers (p <0.05). The odds rate of mild elbow injuries in the control group was 4.625 times higher than the intervention one (95% CI: 1.198; 17.854), the odds rate of moderate injuries in the control group was 5.588 times higher than in the control group than the intervention one (95% CI: 1.143; 27.324). Conclusions. Exercises in closed kinematic chains are an effective means of improving climbing technique and injury preventing to university students during rock climbing.

Introduction. The study aimed to determine the influence of exercises in a closed kinematic chain, exercises in the eccentric mode in combination with proprioceptive muscle facilitation on the level of elbow injuries and technical skills of amateur climbers. Methods. The participants were 84 male amateur rock climbers aged 18-19 years; 40 athletes were in the intervention group and 44 were in the control group. in the intervention group, a developed injury prevention program was used. The program included the application of neuromuscular training. Exercises for proprioceptive muscle facilitation were also performed. We determined the elbow injury incidence rate and confidence intervals and the reliability of the influence of the technique mastery level on the number of injuries by the Cochran and Mantel-Haenszel methods.Results. The use of our program reduced the incidence rate ratio in climbers for mild, moderate, and severe elbow injuries; a significant decrease was found for moderate and severe injuries. There was also a significant improvement in the results of biomechanical analysis of the climbing technique in athletes in the intervention group (p < 0.001). A high reliability was determined of the influence of the technique mastery level on the number of injuries (p < 0.001). Conclusions. The use of exercises in a closed kinematic chain, exercises in the eccentric mode in combination with proprioceptive muscle facilitation reduces the incidence rate ratio of elbow injuries and increases technical skills among amateur climbers.

Introduction: The chronic post-stroke phase is often accompanied by various sensory, cognitive, motoric, coordination, and balance impairments. Decreased strength and motoric control contribute to walking capacity in patients with stroke. This study aims to evaluate the effect of Open Kinetic Chain (OKC) vs Closed Kinetic Chain (CKC) exercise on walking capacity in the chronic post-stroke phase. Open Kinetic Chain (OKC) and Closed Kinetic Chain (CKC) were reported to improve functional mobility and balance in the chronic post-stroke phase. However, there is a lack of studies emphasizing the effect of OKC and CKC on walking capacity. Methods: This study is a quasi-experimental pre- and post-controlled trial group design. Twenty subjects were randomized into two groups of equal size: the CKC group (n=10) and the OKC group (n=10). There was one subject from each group who dropped out at the end of the study. CKC and OKC groups were trained for 6 weeks. The walking capacity was measured with 2 Minutes Walking Test (2WMT). Results: 2WMT results showed improvement in both groups after 6 weeks of intervention, 56,17 ± 10,95 ± to 57,43 ± 11,29 in CKC group (p<0.001) and 57,04 ± 8,58 to 58,19 ± 8,77 in OKC group (p<0.002). Conclusion: CKC and OKC exercise significantly improve the 2WMT results after 6 weeks of intervention.
