Influence of caffeine on metabolic and cardiovascular functions during sustained light intensity cycling and at rest

Article Abstract:

Issues are discussed concerning the effect of caffeine on cardiovascular and metabolic functions during sustained, light-intensity cycling and at rest. A test of eight healthy, recreationally active adults suggested that caffeine's mild thermogenic influence could be mediated without a major shift in substrate oxidation mixture. Caffeine at the dosage level of the test changed cardiovascular dynamics by raising arterial blood pressure.

One hour cycling performance is not affected by Ingested Fluid volume

Article Abstract:

A study was conducted to investigate the effect of different fluid volumes and carbohydrates (CHO) content ingested during cycle time-trial (TT) performance of trained cyclists under thermoneutral conditions. The study recommends that, the fluid replacement should attempt to equal fluid loss, so there is no effect of consumption of different volumes of CHO beverages undertaken by them under such conditions

Dietary antioxidant supplementation combined with quercetin improves cycling time trial performance

Article Abstract:

A study was performed to find out whether 6 weeks of a combination of antioxidant supplementation (AS) and quercetin would enhance 30 km time trial (TT) cycling performance. The empirical results indicate that marked enhancement in the high-intensity cycling TT performance was noticed in athletes who took such a combination of nutrients.
