    Objectives

    The aim of this study was to assess the validity and the reliability of a new fitness intermittent judo test using the basic movement patterns of judo.

    Methods

    Forty-one national level judo male athletes participated in this study. Eighteen judokas performed the intermittent judo fitness test consisting of 10 × 30 s maximal interspersed with 15 second rest, the Australian shuttle test, the special judo fitness test and a judo fight. Twenty three judokas performed twice the intermittent judo fitness test on different days.

    Results

    The results showed significant correlations between the biggest number of Uchi-komi during the intermittent judo fitness test (Uchi-komibest), the longest distance covered during Australian shuttle test and the total projection in the special judo fitness test (P < 0.01). Likewise, a significant relationship was demonstrated between the total Uchi-komi performed in the new judo test (Uchi-komiTot) and both the total distance covered during Australian test and the total projection during the special judo fitness test (P < 0.01). In addition, a significant correlation of the rating of perceived exertion was observed between the intermittent judo fitness test and judo fight (P < 0.05). The intra-class correlation coefficient analysis revealed relatively strong test-retest reliability for Uchi-komibest and Uchi-komiTot (> 0.90). The smallest worthwhile change showed that a change of 2 and 4 Uchi-komi in Uchi-komibest and Uchi-komiTot respectively is occurred.

    Conclusions

    The new fitness intermittent judo test is both valid and reliable measurement tool to assess judokas’ fitness at the basic judo movement patterns.

    Objectives

    The aim of this study was to determine the effect of 8 weeks resistance training with creatine supplementation on body composition and physical fitness indexes in male futsal players.

    Methods

    20 trained futsal players were selected based on convenience sampling from East Azerbaijan and assigned randomly either to Ex + Cr group (Exercise + Creatin, n = 10) or Ex + Pl group (Exercise + Placebo, n = 10). All of the subjects performed resistance training program for 8 weeks. The Ex + Cr group ingested 0.3 g/kg creatine during loading phase 0.1 g/kg in maintenance phase. Body weight, fat free mass, fat percent, muscular strength, speed, anaerobic power and flexibility were measured before and after training program. Paired t-test and independent t-test were used to analyze the data.

    Results

    The results suggested that body weight and fat free mass were significantly increased in both groups with greater improvements in Ex + Cr group (P ≤ 0.05). Moreover, Ex + Cr group demonstrated greater decrease in fat percent compared with Ex + Pl group (P ≤ 0.05). Also, muscular strength increased to a greater extent in the Ex + Cr compared with the Ex + Pl group (P ≤ 0.05). Finally, there was no significant difference between the two groups in speed, anaerobic power and flexibility (P ≥ 0.05).

    Conclusions

    In general, it seems that resistance training along with creatine supplementation lead to greater increases in body weight, fat mass and muscular strength as well as greater decrease in fat percent than resistance training alone in trained futsal players.

    Based on Moon observation, every year, adults healthy Muslims practiced Ramadan intermittent fasting (RIF) for 29 or 30 consecutive days. During RIF Muslims are allowed to food and fluid intake only during night (from sunset to sunrise). Thus, behavioral changes are observed during RIF (e.g., food and sleep habits). Despite these changes, many healthy Muslims maintain their normal habitual physical exercise practice during RIF. However, changes in blood lipids, metabolic markers, electrolytes and hematological parameters during RIF in practitioners of physical activity are yet poorly studied. Therefore, the present review article will summarize the health specific effects of RIF in subjects engaged in physical training during Ramadan.

    Objectives

    Increasing prevalence rate of anxiety disorders in elderly populations especially due to physical limitations has become a key concern for health authorities. Therefore, the objective of the study was to investigate the effects of cognitive and physical training on anxiety in the Elderly.

    Methods

    49 aged females (62.3 ± 2.6 years) with BMI of 35 - 49.99 kg/m2 were assigned to one of three groups: Cognitive (n = 17), yoga (n = 16) and control group (n = 16). The cognitive training protocol focusing on breathing techniques, autogenic training, imagery/visualization, included an 8-week period, three sessions a week. Yoga practices comprising Asana training, Pranaya training, and meditation were conducted 3 times a week, for 8 weeks. The State-Trait Anxiety Inventory was given before yoga practice and cognitive training. Biofeedback devices were used to monitor galvanic skin resistance and resting heart rate. The data were analyzed using independent t-test and one-way ANOVA test.

    Results

    The results indicated that both cognitive and physical training had a significant difference on Anxiety in the training groups (P ≤ 0.05), while no significant change was found for control group (P ≥ 0.05). Furthermore, both training modes decreased the skin potential response (SPR) (P < 0.001). In addition, physical training group had lower resting heart rate after intervention compared to the cognitive and control groups (respectively, P = 0.04 and P = 0.001) lower heart rate and skin conductance level over the entire measurement period.

    Conclusions

    It was concluded that the health benefits of yoga aren’t not specific to maintaining physical health, but also extends to lowering the anxiety in elderly with obesity. It was also suggested that cognitive training can mitigate the anxiety symptoms in the elderly while no physical changes were shown in cognitive training.
