Background: Sleep behavior and movement disturbance (SBMD) is of a relatively high prevalence in children and has a significant impact on their performance in daily activities and quality of life. Snoring, on the other hand, is considered one of the main causes of sleep disturbance in children. This study aims to assess the relationship between snoring and SBMD in 2 to 12 years old children in Qom city.

Materials and Methods: In this case-control study, 100 children with snoring and 100 healthy children were studied over 3 months. The parents took Berlin questionnaire on snoring and childhood sleep questionnaire. Data analysis was done using SPSS software version 18.

Results: There was a significant correlation in mean SBMD between case (13.78) and control (11.45) groups (p<0.001). Independent t-test indicated a significant difference between the case and control groups in the mean of SBMD (p<0.001). Also, significant relationships were seen between snoring and adenotonsilar hypertrophy (p<0.001) and apnea and SBMD (p=0.036), but there was not any relationships between SBMD and age, children less than 7 and more than 7 years old (p=0.231), and severity of snoring and SBMD (p=0.202).

Conclusion: This study demonstrates the importance of sleep disorders, especially snoring and SBMD and their relationship, in children. Sufficient attention to this issue can raise parents and physicians awareness and pave the way for early diagnosis and treatment of these disorders.

Background: Delayed muscular soreness after resistance exercises or eccentric trainings is probably because of muscle damage and injury. Nutrition by playing a crucial role in both protein synthesize and catabolism can influence the extent of muscle injury. The objective of this study was to assess the effect of single portion of Glutamine supplement consumption on injury indices of muscle after a session eccentric resistance exercise.

 Materials and Methods: This study used a randomized, double blind design that consisted of 80 volvnteer non-athletic males (aged 22.2±2.2 years, height 175±5 cm, weight 71.64±9 kg, body mass index 23.2±2.2 kg/m2, and body fat 17.5±2.4%). A total of 40 participants were divided randomly into 2 groups, supplement group (receiving 0.1 g/kg Body weight/day Glutamine) and placebo group (receiving 0.1 g/kg Body weight/day Maltodextrin). Serum keratine kinase (CK) was determined by photometric method, muscle pain and knee joint range of motion were measured using, respectively, a standard scale of PAS and goniometer before, 24 and 48 hours after a resistance test involving knee flexion.

Results: Glutamine supplement consumption caused no significant differences in CK levels reduction in none of the measured times, but it reduced the muscle pain at the times of 24 and 48 hours in comparison with the placebo group. In addition, the knee joint range of motion was significantly improved at 24 hours after the test.

Conclusion: It seems that this dose of Glutamine supplementation can reduce the apparent signs apart from muscle injury indices reduction.
