- Background The influence of various physical exercise frequencies on postural balance and muscle performance among young persons with intellectual disability (ID) is not well understood.Method Cross-sectional data from 26 elite athletes were compared with 37 students at a sports school and to 57 students at a special school, all diagnosed with mild to moderate ID and with different exercise frequencies. Data were also compared with a group of 149 age-matched participants without ID.Results There were no significant differences in postural balance between young ID groups regardless of physical exercise frequency, all of them had however impaired postural balance compared to the non-ID group. The group with high exercise performed better than the other ID groups in the trunk muscle endurance test.Conclusions It appears as if physical exercise frequency don’t improve postural balance but endurance in the trunk muscles for young persons with ID.

- This study examines postural muscle responses to backward perturbations in young people (16-20 years) with and without intellectual disability (ID). The study included 56 young people with ID and 43 age-matched without ID volunteers. The subjects stood on a platform that was moved backwards in a surface translation. Lower and upper leg muscles and lower back spine muscles were recorded with surface electromyography (EMG). Muscle onset latency, time to peak amplitude (EMG), adaptation of muscle responses to repeated perturbations (using integrated EMG (IEMG) for epochs), and synergies and strategies were assessed. The result showed no differences between the two groups in muscle onset latency, synergies, and strategies. Young people with ID reduced their time to peak amplitude in investigated muscles, a response that was different from the group without ID. Also, young people with ID tended to adapt their IEMG less compared to the controls. These findings suggest that young people with ID have limited ability to use somatosensory information and adapt their postural muscle responses to repeated external perturbations.

- Background: Postural balance training is primarily used by athletes as rehabilitation after previous injuries or for prevention. A few studies have been made with the aim of investigating whether postural balance training can improve other physical functions in healthy participants. However, there is no consensus regarding effects.Objective: The aim of this study was to investigate whether postural balance training can improve muscle function in healthy adult athletes.Method: Seventeen healthy adult (6 males and 11 females) athletes between the ages of 21 and 50 years performed three postural balance exercises once a day 3x30 seconds per exercise on each leg. This intervention was performed daily for six weeks. Their muscle function were assessed with squat jump, heel rise and grip strength (control). Evaluation was done before and after the training period.Results: Jump height, number of repetitions in heel rise and duration in standing on one leg increased with statistical significance. There were no improvements in postural sway and grip strength.Conclusion: The results suggest that a postural balance training period can provide a better local muscle function regarding explosive strength and endurance among adult athletes even if postural sway is not affected.

- BackgroundAs physical activity can prevent overweight and promote general health, the aim was to investigate the amount of physical activity among adolescent and young adult women and men with intellectual disability (ID), compared to age-matched control groups without intellectual disability. A further aim was to examine whether physical activity level was associated with the body mass index (BMI).Materials and methodsFifty-two adolescent and young adult women and men with intellectual disability and 48 without intellectual disability, between the ages 16 and 20 years, BMIs ranging from 16.3 to 50.3 kg/m2, were measured for number of steps taken with a pedometer for five consecutive days (Sunday–Thursday).ResultsThe only group to meet recommendations regarding number of steps (10 000–12 000/day) was women without intellectual disability. No significant associations were found between total number of steps taken and BMI.ConclusionAs the majority of adolescents and young adults with intellectual disability, especially women, did not reach recommended activity levels regardless of their BMIs, this call for broad measures to increase physical activity.
