Abstract
Aim: One of the methods used to improve sports performance is the use of carbohydrate mouth rinse. The purpose of this study is to investigate the effect of carbohydrate mouth rinse on the specific performance of trained soccer players.
Methods: Eighteen professional football players (22 ± 2 years) were randomized into two groups of carbohydrate mouth rinse (CMR) and placebo (P) in a fasted state after eight hours of sleep. During the two main test sessions, players were provided with either a color- and flavor-matched carbohydrate drink or a no-calorie drink (placebo) for a mouth rinse in a double-blind randomized crossover design. Players were asked to rinse the carbohydrate solution in their mouth for 10-15 seconds and then return it to the plastic cup. Sprint performance, maximum height jump, and 30-15 intermittent fitness test (30-15 IFT) were taken from the subjects.
Findings: Carbohydrate mouth rinse increased running distance in 15-30 IFT test. While there was no significant difference between the two groups in the performance of the 30-meter speed test and the maximum vertical jump.
Conclusion: Therefore, those soccer players who are unable to drink carbohydrate solutions due to digestive problems are advised to use the carbohydrate mouth rinse way to improve their performance during the game.

Abstract
Sports injuries hold significant importance due to several reasons such as injury types and their nature, identifying risk factors associated with these injuries, the effectiveness of sports equipment, and individual variations in injury occurrence. Common among athletes, these injuries range from sprains and strains to fractures, significantly impacting their performance. One of the methods to prevent all kinds of injuries is the use of smart textiles and wearable technologies. Smart textiles refer to textile-based structures that have the ability to sense or react to various stimuli, including physiological variables of the body. These structures play a significant role in monitoring the performance of athletes in various disciplines and improving sports injuries, both among athletes and at the community level. This study reviews the definitions, nature, and types of sports injuries, and the principles and application of smart textiles in sports. Moreover, heat-generating smart textiles as a method of improving and treating sports injuries are explained. Information was collected through searches on Google Scholar and Semantic Scholar using keywords such as "sports injuries," "smart textiles," "wearable technology," and "heat-generating textiles" within the time frame of 2000-2023. The review followed a systematic approach, including defining the topic, selecting relevant databases, and using a combination of keywords to gather comprehensive and representative sources. The most significant findings from the reviewed articles include the effectiveness of heat therapy in reducing muscle soreness and promoting recovery, the role of smart textiles in injury improvement, and the advancements in wearable technology for monitoring and improving athletic performance. Flexibility, air permeability, and temperature control were among the features of textile-based structures designed and investigated in various studies. Previous studies also showed that the textile structure and the type of conductive materials, such as conductive polymers and conductive yarns, affect its heat generation capability and uniformity. Moreover, the use of conductive yarns showed more technical advantages, such as higher uniformity in heat generation compared to other proposed methods.
