The goal of this clinical trial is to assess the effects of a 6-week strength training program with elastic bands on several physical components in adult female football players. The main question it aims to answer is:
Will a specific elastic band resistance training help improve some components of physical performance in adult female football players?
Participants will perform a bi-weekly elastic band resistance training, during a period of 6-weeks. This program will be incorporated into their in-season regimen, before their training session.

| Measure | Description | Time Frame |

| Knee extension and flexion isometric strength | Maximal isometric knee extension and flexion force will be measured using a handheld dynamometer (DynaMo Plus, VALD Performance, Brisbane, Queensland, Australia). For the knee extension assessment, participants will be in a seated position, whereas during the knee flexion evaluation, the participants will be in a prone position. To generate their maximal torque, the dynamometer chain length will be adjusted so that their knee angle will be at ∼60° and ∼30°, for the knee extension and flexion, respectively. Participants will then apply a maximal isometric effort, maintaining it for 5s, without any subsidiary body movements. | At the beginning and end of the study (Week 1 and Week 6) |
| Vertical jump | Jump height was evaluated using an optical measurement system (OptoJump, Microgate, Bolzano, Italy). The players will perform the countermovement jump, where they will begin from an upright position; a rapid downward movement to a knee angle of ∼90°, immediately transitioning to propel themselves upwards into the air. | At the beginning and end of the study (Week 1 and Week 6) |
| Change of direction sprint | The Modified T-Test will be implemented to assess change of direction sprint. This evaluation has within itself directional changes such as forward sprinting, left and right-side shuffling, and backpedaling. Photocells (WhittyGate, Microgate, Bolzano, Italy) will be used for a more precise time count. | At the beginning and end of the study (Week 1 and Week 6) |
