| Incremental until reaching maximum stimulus | It starts with an intensity of 20–30 mA and increases progressively in 10 mA or in 5 mA until reaching the maximal stimulator output (110 mA). | García-García et al7 | 0.98b–0.97a | Professional soccer players |

| Incremental until reaching “plateau” | It starts with an intensity of 20 mA- 30 mA and increases progressively, generally in 10 mA until the Dm suffers a descent or a flattening of the curve called “plateau” | Alvarez-Diaz et al19 | - | Soccer players |
