Carbohydrate Loading and Squash Performance
High Carbohydrate Diet and Squash Performance
Carbohydrate loading before a squash match can significantly enhance performance. A study involving New Zealand level squash players demonstrated that a high carbohydrate diet (11.1g/kg body weight) consumed 48 hours before a simulated squash match increased carbohydrate oxidation during the match and improved physical performance. Players on the high carbohydrate diet completed the games faster and had higher blood glucose and lactate concentrations compared to those on a low carbohydrate diet (2.1g/kg body weight) . This suggests that a high carbohydrate intake can be beneficial for maintaining energy levels and enhancing performance in squash.
Carbohydrate Content in Squash Varieties
Different varieties of squash have varying carbohydrate contents, which can influence their nutritional value and resistance to pests. For instance, the carbohydrate content in squash seeds varies significantly among different lines, with some seeds having higher carbohydrate levels than others . Additionally, the carbohydrate concentration in squash fruits can affect their resistance to pests like the pickleworm. Higher D-glucose concentrations in squash varieties are associated with increased resistance to the pickleworm .
Developmental Changes in Squash Carbohydrates
The carbohydrate content in squash changes as the fruit develops. Studies on varieties like Ebisu and Kogiku have shown that soluble sugar content increases during development, while glucose content remains relatively stable. The properties of starch granules, such as size and amylose content, also change during development, which can affect the texture and cooking properties of the squash .
Carbohydrate Analysis in Squash Using NIR Spectroscopy
Near-infrared spectroscopy (NIR) has been used to predict the carbohydrate content in zucchini, a type of squash. This method allows for the differentiation between less sweet and sweeter zucchini accessions and can effectively predict the content of individual sugars like glucose, fructose, and sucrose, as well as starch . This technology can be useful for breeders and farmers to select varieties with desired carbohydrate profiles.
Carbohydrate Intake and Cognitive Performance in Squash
Carbohydrate intake not only affects physical performance but also cognitive functions in squash players. Ingesting carbohydrates before and during exercise has been shown to improve reaction times and visual scanning tasks, which are crucial for maintaining high levels of motor and cognitive skills during a match 68. This highlights the importance of carbohydrate consumption for both physical and mental aspects of squash performance.
Conclusion
Carbohydrates play a crucial role in squash, influencing both performance and nutritional value. High carbohydrate diets can enhance physical performance and cognitive functions during matches, while the carbohydrate content in different squash varieties can affect their nutritional value and resistance to pests. Understanding these aspects can help athletes optimize their diet for better performance and assist breeders in developing squash varieties with desirable traits.
