What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| ergospirometry variable: heart rate | It was done with a bicycle with electromagnetic resistance (Spin Trainer ;Technogym). Heart rate was measured in beats per minute. | The change was evaluated after one month of product consumption. | 
| ergospirometry variable: absolute oxygen consumption | It was done with a bicycle with electromagnetic resistance (Spin Trainer ;Technogym).It was measured in milliliters per minute | The change was evaluated after one month of consumption of the product | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| ergospirometry variable:respiratory ratio | It was done with a bicycle with electromagnetic resistance (Spin Trainer ;Technogym). Through the oxycon pro jaeger gas analyzer. | The change was evaluated after one month of consumption of the product | 
| ergospirometry variable: oxygen equivalent | It was done with a bicycle with electromagnetic resistance (Spin Trainer ;Technogym). Through the oxycon pro jaeger gas analyzer. | The change was evaluated after one month of consumption of the product | 
| blood variables: Natremia, potassium, chloremia, calcemia, , bicarbononatemia, ph, lactacidemia. | The following variables were analyzed: The variables are analyzed using the ABL 77 radiometer. The unit of measurement is mmol / L. | The change was evaluated after one month of product consumption. |
