A complex and dynamic environment where impulsivity probably interferes in the human behavior is the sport context. The aim of this exploratory study was to investigate the possible relationship between impulsivity and technical performance in handball athletes. Eleven junior female athletes on a handball team were submitted to a neuropsychological assessment of impulsivity using Conner's CPT-II and the Iowa Gambling Task. In 11 matches, participants' handball performance was analyzed. We adopted the resampling statistical approach to correlate the measures of technical performance with the neuropsychological measures. IGT net score was positively correlated with technical faults. Omission errors on the CPT-II were positively correlated with the number of fouls suffered, the number of fouls committed, and the number of offensive fouls. Commission errors on the CPT-II were negatively correlated with rebounds with defense ball possession. Our results support the idea of relationships between impulsivity and technical performance in specific match situations.

Since the beginning of the pandemic, the population has been exposed to a substantial period of social isolation, which leads to anxiety, fear, and metabolic and immune impairments. Purpose Considering that sleep restriction influences eating behavior, we highlight that changes in it may occur during the COVID-19 quarantine. Alterations in feeding time can uncouple the body clocks, leading to circadian misalignment and consequently to a disruption in homeostasis and disturbances in many metabolic functions. Method Narrative review. Results Do not apply. Conclusion The increase of body weight is related to increased food intake in response to mental stress and more time spent at home, increased opportunity to feed, and increased visual and olfactory stimulation to eat, which represents a potential risk of overfeeding nowadays. In this article, we postulate that the unusual lifestyle imposed by the COVID-19 quarantine may induce a circadian misalignment, which is capable to induce alterations on eating and sleep behaviors.

Body image represents the mental perception of body shapes and is a multifactorial structure that includes psychological, physical and emotional elements. The discrepancy between the subjective perception of body image and the desire for the ideal body type can interfere with the feeling of satisfaction and trigger the desire for changes in appearance, directly interfering with mental health and general well-being. Men and women may differ in body image satisfaction due to the different social influences and beauty standards imposed. The aim of this study was to evaluate the subjective perception of body image and satisfaction with body shapes among men and women. The sample consisted of 100 college students of both genders. Subjective perception of body image and satisfaction were measured through self-assessment, through scale figure silhouettes. There was a significant difference in the subjective perception of body image in the comparison between genders, and women presented greater discrepancy between the real and the perceived image. In the analysis of satisfaction with body image there were no differences between genders and both presented high percentage of dissatisfaction. In addition, 46.2% of men would like to decrease their body shapes, 53.8% would increase them. As for women, 76.1% would like to decrease their body dimensions and 23.9% to increase them. The strong pressures imposed by society and the standards set by the prevailing media in determining body image dissatisfaction or self-assessment negatively, regardless of gender.

BACKGROUND: Individuals with spinal cord injury (SCI) present thermoregulatory impairments that prejudice thermal compensation and heat dissipation during exercise practice. Thus, cooling vests (CV) seems to be a promising strategy to attenuate it. OBJECTIVE: Our aim was to evaluate the efficacy of CV in controlling the rise in body temperature and in enhancing exercise performance in individuals with SCI. METHODS: The searches were performed in PubMed, Web of Science, Scopus, PEDro, and SciELO databases. We selected randomized controlled trials, quasi-randomized trials, or cross-over trials that evaluated the efficacy of CV before or during exercise practice in thermoregulatory responses and exercise performance of individuals with SCI. RESULTS: A total of 400 reports were identified through databases searches and another article was found through citation searching. Seven cross-over trials were included in this review after the screening processes. CONCLUSION: CV may not be effective in attenuating the rise in core temperature in persons with SCI, but it seems to be effective in controlling skin temperature and in improving thermal comfort/sensation. It is unclear whether the CV is more effective when applied before or during exercise practice. Individuals with tetraplegia may benefit more and the CV may be more effective in strenuous exercises.
