Physical conditioning Heart rate Anaerobic threshold
Conditions
Interventions
Experimental groups: 40 untrained young will take only one caffeine pill (n=20
100 mg) or one green tea extract pill (Camellia sinensis) (n=20
500 mg). Control group: 20 untrained young will take one placebo pill (100 mg of maltodextrin). All the participants take the single dose of pill 30 minutes before the treadmill-test protocol

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| A non-linear increase in ventilatory anaerobic threshold in volunteers that had taken the green tea pill. To the ventilatory anaerobic threshold assessment will be used a gases analysis equipment. To the verification of this outcome, will be considered a variation of at least 10% in relation to caffeine group and 20% in relation to placebo group | — |
Secondary
| Measure | Time frame |
|---|---|
| An increase of at least 20% in heart rate variability, verified by heart monitor, in volunteers that had taken the green tea pill in relation to caffeine group and 30% in relation group to placebo group | — |
