Sport-X - Carbo-Load
“OPTIMIZE THE FUEL TANK LEVEL PRIOR TO THE EVENT”
- Supply nutrients that regulate the “carbo-loading” processes in the muscle and liver tissue hours prior to a sport event.
- To enhance endurance and power output during the sport event. (Use 4 to 5 hour before the event)
Once the glycogen content in the active muscle tissues drops to critically low levels, high-intensity exercise cannot be sustained and the athlete drastically reduces the pace despite sufficient oxygen being available to muscle tissue and an almost unlimited potential energy from stored fat.
Cyclists therefore embark on various carbohydrate depletion-loading strategies (glycogen super compensation) to raise the glycogen content in the active musculature prior to an event.
Although the glycogen content increases above sedentary levels with these dietary and/or exercise-induced protocol regimes, metabolic waste products tend to accumulate in the glycogen-deprived muscle tissues during the carbohydrate-depletion phase. The concomitant increase in the amount of metabolic waste products impairs the power output generated by a muscle bundle.
It could take up to seven days or more before the metabolic waste products are removed from the musculature. It is therefore not surprising to find that many athletes gain no performance benefit from carbohydrate depletion-loading strategies.
The ultimate challenge is to super-compensate during a sedentary state without depriving muscle tissue from glucose during the carbohydrate depletion and loading phases prior to an endurance event. The specific combinations of the ingredients in the first set of capsules to be taken within the hours prior to the race meet this demand, i.e. increase carbohydrate reserves in liver and muscle tissues.
Scientific Detail
1. Amino acids stimulate glycogen synthesis in muscle tissue
Figure 1 shows that the oral ingestion of different types of amino acids does not stimulate/inhibit glycogen synthesis in different muscle bundles to the same extent. Some amino acids, however, enhance glycogen formation in all different muscle fibre types simultaneously. However, the magnitude of the stimulating properties on glycogen synthesis in the different muscle bundles varies. Control values are indicated by the red bars.

2. The combination of specific amino acids and the amino acid ratio within a specific amino acid combination, enhance glycogen synthesis in different fibre types simultaneously.
Figure 2 suggests that the diet enriched with GPA 37-18-18 for example, showed an increase in the glycogen concentration in the soleus with at least 22% of the population, but the value could be as high as 104% (mean 63,5% for the present study). The corresponding values for the gastrocnemius show an increase of 3% to 74% (mean 35% for the present study).
When the proportional ratios of the amino acids in the GPA 37-18-18 mixture are altered (GPA 18-37-18) in such a fashion that the total amount that is ingested remains equal, a trend towards a decease in the glycogen content occurred in these two groups in all different muscle groups studied. However, a significant difference between the GPA 18-37-18 and the control groups still exists.

When the concentration of the GPA 37-18-18 group was doubled (GPA 140) or tripled (GPA 175), no significant differences between these groups and the control group were noted. However, it seems possible that the results pertaining to the latter two interventions (GPA 140 & GPA 170) could be misleading and fallible, since the dietary intake (volume of food ingested) of these groups was reduced. A dramatic improvement in glycogen synthesis could have sustained blood glucose levels for longer periods in time, thereby suppressing the appetite and influencing the actual amount of glycogen formed accordingly.
Furthermore, amino acids seem to be more effective than carbohydrate (glucose) to stimulate glycogen synthesis. On a mass-to-mass basis the glucose 420 group ingested 6 times the amount of glucose compared to any of the amino acid groups.
It should be noted that the present results also indicate that the combinations of the said amino acids enhance glycogen formation in sedentary muscle tissue. This finding is in contrast with the findings propagated in the literature where active muscle tissue seems to be a prerequisite for glycogen synthesis when other dietary manipulating strategies are implemented. The results also suggest that the blue capsules enhance the absorption of carbohydrate (glucose) and stimulate glycogen synthesis (carbo-loading) in skeletal muscle tissue in the presence/absence of exercise-induced and/or dietary-manipulating regimens, i.e. a sedentary state.
