Another study had similar findings, it was reported that consuming caffeine before as well as during a round of golf improved performance, and increased subjective energy levels while reducing feelings of fatigue.
Coffee may be linked to a lower risk of type 2 diabetes
Some research suggests that consuming coffee regularly for a long time could be associated with a decreased risk of developing type 2 diabetes.
A review of 30 studies found that a cup of coffee people consumed per day was linked to a 6% lower risk of developing type 2 diabetes.
This is thought to be due to coffee’s ability to preserve the function of the beta cells in the pancreas. As beta cells are responsible for producing insulin to regulate blood sugar levels. Coffee’s rich in antioxidants and may affect insulin sensitivity, inflammation, as well as metabolism, all involved in the development of type 2 diabetes.

Compellingly, a test-tube study showed that coffee was able to significantly extend the life span of yeast by protecting against free radicals as well as DNA damage.
However, further research is required to determine whether this could also apply to humans.
Coffee may enhance athletic performance
Coffee is often used as an ergogenic aid by athletes who wish to improve performance along with increasing energy levels. Coffee is called an ergogenic aid, or a performance enhancer.
A review of nine studies reported that drinking coffee before exercise improved people’s endurance while also decreasing their perceived exertion, compared with a control group.
A study on 126 older adults found that drinking coffee was associated with improved physical performance and faster gait speed. Even after the researchers adjusted for factors like age, belly fat, as well as physical activity levels.
Additionally, a huge review reported that moderate consumption of caffeine could slightly improve power output along with time-trial completion time. However, results varied, researchers also noted that caffeine may affect people differently.
