    Objective

    The present review was designed to systematize the literature on the evolution of dietary intake in Tunisian physically active subjects (i.e., physically active men and physical education students) between before, during and after Ramadan observance.

    Evidence Acquisition

    Two electronic databases, PubMed and Science direct, were searched using a comprehensive strategy. Studies published prior to August 2018 were included if they assessed dietary intake during Ramadan in Tunisian physically active subjects. A narrative synthesis of findings was conducted.

    Results

    Nine studies evaluated the dietary intake change between before, during and after Ramadan observance. Energy intake decreased in three studies and did not change in six studies. One study showed decreases in fat intake during Ramadan, two studies reported increases and six studies did not report significant changes. Protein intake decreased in three studies, increased in one study and did not change in five studies. Carbohydrate intake did not change in six studies and increased in three studies. Total water intake decreased in four studies and did not change in one study.

    Conclusions

    The literature does not support that Ramadan fasting had adverse effect on dietary intake.

    Mawashi-Geri Jodan technique (circular kicking to the opponent’s head), is one of the most commonly used techniquesin the Karate, especially in the combat style. Although the speed of the implementation of the technique plays an important role in gaining points, there is no specific pattern for optimal performance of the technique. In this research, it was aimed at reviewing the results of the previous research that has been conducted on the effective issues relating to the success of this technique performance. The related articles were searched in ScienceDirect, PubMed, Google Scholar by considering the words like Karate, biomechanics, kinetic and kinetic analysis, EMG of Mawashi-Geri and EMG of kick. In the years ranging from 2000 to 2018, the findings of the research showed that the quadriceps muscles, especially rectus femoris muscle, played a major role in the efficacy of technique performance. Keeping the knee upward while rotating the body, the technique will be performed faster due to closer distance toward the opponent. Therefore, Karate player can obtain the required score more easily and quickly. It seems that the use of this pattern will be effective in performing the technique of Mawashi-Geri in Karate.

    Background

    Treatment methods for autistic spectrum have been of utmost interest for researchers. In this regard, nature therapy is one of the most cost-efficient methods of treatment. Considering this issue, the aim of this study was to investigate the effect of family-centered nature therapy on the sensory processing of children with autism spectrum.

    Methods

    This study was an applied and semi-experimental (pre-test and post-test) with control group. The statistical population included all children with autism spectrum disorder (3 - 7 years old) referring to Tehran’s rehabilitation and therapy centers. The sample size of 14 children (12 males and 2 females) with autism spectrum disorder was selected by convenience sampling method and were randomly divided into experimental and control groups. Ten sessions of nature therapy were held at Sagan Nature School along with parents’ mandatory attendance. To collect the data, the sensory evaluation checklist and the Nature Therapy Schedule were used based on theoretical framework and research findings. The obtained data were analyzed using Leven, Kolmogorov-Smirnov and covariance analysis tests.

    Results

    Based on the obtained results, nature therapy had a significant effect on sensory processing in experimental group (F = 22.42; P = 0.001). Furthermore, eta coefficient of 0.67 indicated that approximately 67% of the variance of the dependent variable (sensory processing) is affected by the study intervention.

    Conclusions

    The findings showed that family-centered nature therapy reduced some sensory problems in children with autism spectrum disorders. These children, especially in motion and touch, showed significant progress. Therefore, this method can be used for reducing the syndrome of children with autism spectrum disorder due to its positive, simple, and beneficial effects as a complementary therapy along with other therapies.
