“…Therefore, it can be reduced or even prevented by the use of antioxidants. Aloe vera is a plant known to have an antioxidant effect, widely used as an ingredient in healing burns caused by sun exposure (Tester and Al-Ghazzewi, 2017). However, it is not yet known whether Aloe vera can reduce SBC number and apoptosis of keratinocyte cells due to exposure to UV light.…”

Introduction: Ultraviolet B (UVB) radiation triggers the formation of free radicals that cause apoptosis and sunburn cells (SBC) formation. Aloe vera contains anti-inflammatory and antioxidant compounds that can potentially inhibit this process. Objective: to assess the effect of topical Aloe vera extract administration on the decrease of SBC number and Caspase-3 expression on the epidermis after UVB light exposure. Methods: In a post-test only group design study, a single dose of 3 doses of Erythema (DEM) was performed on two groups of 6 week old BALB/c female rats. Group A (control) did not receive any topical treatment, and group B (treatment) were smeared with 75% Aloe vera extract before irradiation. Each group was divided into 4 sub-groups based on post-exposure time of 6 hours (A1 and B1), 12 hours (A2 and B2), 24 hours (A3 and B3), and 48 hours (A4 and B4). The expression of caspase-3 was assessed by immunohistochemical staining while the SBC number was measured using a microscope. The expression of caspase-3 was analyzed using the Kruskal-Wallis and Mann-Whitney statistical tests, while the number of SBC was analyzed using the one-way ANOVA statistical test and the post-hoc LSD test. Results: The results of the Kruskal-Wallis analysis showed a significant difference in Caspase-3 expression between groups, p <0.05. The results of Mann-Whitney analysis showed a significant difference in Caspase-3 expression between the A1-A3 and B1-B3 subgroups (p <0.05). One-way ANOVA analysis showed a significant difference in the number of SBC between groups (p <0.05). Post-hoc LSD analysis showed significant differences in SBC counts between groups A and B across all subgroups, p <0.05. Conclusion: Topical application of Aloe Vera extract decreased Caspase-3 expression and the number of SBC in UVB light-exposed skin.

“…Among these reactions is the stimulation of fibroblasts with the subsequent increase of production of collagen around wounds and burns [113]. Among other claims are some effects on infections, but the results are still conflicting, and the studies usually lacking significant impact (for a review, see Tester and Al-Ghazzewi [114]).…”

In recent decades, various polysaccharides isolated from algae, mushrooms, yeast, and higher plants have attracted serious attention in the area of nutrition and medicine. The reasons include their low toxicity, rare negative side effects, relatively low price, and broad spectrum of therapeutic actions. The two most and best-studied polysaccharides are mannan and glucan. This review focused on their biological properties.

“…It helps the excretion of bile acids, and soaks up water, thereby bulking up the faecal mass. the specific action of the glucomannans, increasing immune surveillance (67) . If the athlete needs more energy, he must increase the number of meals and snacks rather the size of the meals to avoid larger release of pancreatic insulin.…”

Soccer is characterized by repeated sprint ability which is conditioned by the efficiency of both the anaerobic and aerobic energy systems. Energy supply for soccer performance relies directly on the nutritional habits, usually inadequate in many soccer players. So, correct nutrition is a crucial factor toward soccer highest performance. The type and quantity of foods and timing of meals can influence both sport performance and recovery's capacity. Optimal nutrition contributes to improve physical conditioning, mental accuracy and faster recovery after workouts or matches. Soccer players need to achieve good nutritional habits in order to get the body weight related to the maximum performance and to maintain health. This short review intended to establish some nutritional guidelines which can help soccer players to achieve and maintain an optimal body composition and maximize energy availability for training and matches.
