Individuals with intellectual disabilities (ID) often exhibit lower levels of physical fitness compared to the general population, including reduced strength, endurance, flexibility, and coordination. Dynamic neuromuscular stabilization (DNS) training can potentially improve the performance of adults with ID caused by weak motor skills due to a lack of desirable nerve growth during childhood and before puberty. Also, DNS training proposed to improve physical fitness in this population, but the effectiveness and durability of DNS training on specific fitness components have not been well-established. This study employed a randomized controlled trial design to investigate the effects of an 8-week DNS training program on the strength, endurance, and flexibility of adults with ID. A total of 31 participants were randomly assigned to either an intervention group (n = 16) or a control group (n = 15). Muscular strength, endurance, and flexibility were assessed at baseline (pre-test), immediately after the intervention (post-test), and 2 months following the intervention (follow-up) using the 30-second chair stand (30sCS) test, sit-ups test, trunk lift test, and chair sit-and-reach test. Participants in the intervention group engaged in the DNS training program for 8 weeks, with 3 sessions per week, while the control group maintained their usual activities. The analysis of the outcome measures revealed significant time, group, and time-group interaction effects. Post-hoc analyses indicated that the DNS group exhibited significantly greater improvements in 30sCS, sit-ups, trunk lift, and chair sit-and-reach compared to the control group (p < 0.01). These improvements were maintained at the 2-month follow-up assessment in the DNS group. This randomized controlled trial demonstrates that an 8-week DNS training program significantly improves muscular strength, endurance, and flexibility in adults with ID, with benefits maintained at a 2 month follow-up. Further research is needed to replicate these findings and investigate underlying mechanisms, but the study highlights the potential of DNS training to promote physical fitness and well-being in individuals with ID.

Purpose: This study aims to conduct a systematic review of injury prevention programs on muscle flexibility in children and adolescents. Methods: Relevant articles were searched in two electronic databases, PubMed and Scopus. An electronic search was conducted on December 1, 2022, without applying any year constraints. Studies that investigated the effect of injury prevention programs on muscle flexibility in subjects under 17 years of age were included. The study method was evaluated using the PEDro scale. Results: A total of 3563 studies were initially retrieved from databases, and data from 5 randomized controlled trials (RCTs) were used in this systematic review. Injury prevention programs (three out of five articles) can improve the muscle flexibility of children and adolescents (before and after the intervention). Conclusion: Injury prevention programs can improve the muscle flexibility of children and adolescents in the intervention group (before and after the intervention); although no improvement was observed in the control group. Therefore, factors, such as duration, frequency and intensity of the program, gender, activity level, type of sport, and sample size are decisive in muscle flexibility. [ABSTRACT FROM AUTHOR]

Introduction and Aim. Functional Movement Screening (FMS™) tests provide beneficial information regarding the movement and stability in the kinetic chain. The core region of the body, as the basis of movement chain, accounts for the facilitation of force and torque transmission. The aim of the present study was to investigate the relationship between functional movement screen composite scores and core stability muscles endurance in athletes. Material and Methods. Forty-five male athletes with FMS scores ≤14 (LoFMS) and forty-five male athletes with FMS scores >14 (HiFMS) were studied. Stability of core muscles of the participants was investigated and compared using the McGill's test. Results. The results of this study showed a significant difference in the mean stability of the anterior trunk muscles (p = 0.001), right side trunk muscles (p = 0.005) and left side trunk muscles (p = 0.001) between the athletes with LoFMS and HiFMS scores. Muscles' endurance in the group with HiFMS score was significantly higher than the group LoFMS score (p = 0.001). However, there was no significant difference in the mean stability of the posterior trunk muscles between the two groups. In general, a significant difference was found between sum of core stability scores obtained from lumbar-pelvic stabilizer muscles in the posterior, anterior and lateral sides of athletes LoFMS and HiFMS scores. Conclusions. The results of this study showed that weakness in core stability can have a negative influence on movement patterns. [ABSTRACT FROM AUTHOR]
