Different athletic events require different chemical responses from the body, so you need to know what biochemical response is required of your body during an athletic event. Your chemical power requirements can be categorized by the duration and intensity of the athletic event. For each event, the required chemical response must be correct in terms of both timing and biochemistry.
The type of carbohydrate used in your sports drink and its attendant glycemic impact should correspond to the required chemical response. The bottom line is that your sports drink, or drink of choice, will directly affect your ability to access adequate power, energy, stamina, and muscular output. Your ability to perform and win depends on your body’s ability to deliver power when you need it.
 
 
Target Chart
The Human Maximum Performance “Target Chart” allows you to identify your desired glycemic response. The Target Chart identifies specific athletic events. To identify your chemical-power category, select the event you will be involved in and its corresponding duration. The Glycemic Response Required listed on the chart tells you what targeted response you will need for that event.
The body will immediately respond to the instructions it receives via the glycemic response and nutritional-dynamics of the drink you select. If the event requires that the body burn glucose contained in muscle cells or if glucose from the blood stream has time to enter the muscle cells, or a combination of both, you will need to make the avenue available.
The object is to get your body to respond to the biochemical instructions you give it. You are actually targeting a specific biochemical reaction.
