Intense physical exertion is an immense metabolic challenge for the body as it requires efficient functioning of various biochemical pathways involved in the process of energy acquisition, required in quantities even 20-30 times greater than at rest. Carbohydrates (and more precisely glucose) are the main source of energy in all types of physical activities. Source of energy in the body for working muscles:
- muscle glycogen, an abundant source of energy during workouts of up to several dozen minutes,
- hepatic glycogen, the main source of glucose during long-lasting physical exercise of moderate intensity.
Glycogen reserves are successively depleted during workouts. When the duration of physical activity with moderate intensity is significantly prolonged, the free fatty acids, from the degrading of adipose tissue, take over as the main source of energy for the working muscles.
In order to maintain high intensity of physical performance, sportsmen are recommended to take in carbohydrates during exercise (1, 2) which is especially important during workouts longer than 1 hour. In such case sportsmen should consume carbohydrates in about 0.7 g/kg bw/h, and the recommended carbohydrate consumption level for professional sportsmen, experiencing additionally high physical stress, may be as much as 90 g/h (during workouts longer than 2 hours). Studies show also that carbohydrates should be taken in as a mixture of glucose and fructose which significantly increases the rate of exogenous carbohydrate oxidation and physical performance (3) compared to carbohydrates which provide only glucose (4, 5, 6).
ADVANCED COMPLEX OF ENERGY-RICH INGREDIENTS!
FIRE START™ energy gel:

- 1 serving contains as much as 45 g pure carbohydrates from as many as 5 sources with different absorption kinetics, composed of glucose and fructose, supporting energy generation in anaerobic processes.

- MCT oil - ultra-concentration energy - source of twice as much energy compared to energy derived from the same quantity of carbohydrates. Triglycerides composed of medium-chain fatty acids, which on absorption in the digestive system may be used much more rapidly by the working muscles (compared to normal-chain fatty acids) are substrates for energy generation in aerobic processes. Studies show that short-term intake of small quantities of MCT oil may reduce the blood level of lactic acid and subjective fatigue level, thus prolonging effective workout to a significant extent.

- Beta-alanin - one of the essential substances preventing decrease in intracellular pH which may have a negative impact on the efficiency of ATP formation, thus reducing the level of physical performance.

- Glucuronolactone - takes part in detoxificatin of the body (8), while acting synergistically with beta-alanine.
- Caffeine - increases the speed of signal transmission in the nervous system and strength of muscle contraction, with highly lower frequency of stimulation, additionally reduces the use of glycogen reserves in the body, instead accelerating the release of fatty acids from adipose tissue. This profile of effects brings significant advantages, especially during endurance exercises, and their duration is limited with the level of glycogen reserves in the body (9).

- The other ingredients of the product show synergistic effects in supporting intense work of the nervous system (including magnesium) or a conversion of carbohydrates and proteins (B-group vitamins), and antioxidants (vitamin C, E) help to protect cellular proteins against degrading effects of free radicals which are generated in large quantities during prolonged physical activity.
