Introduction: Paddle tennis is a popular sport which can cause lower limb injuries due to impaired flexibility, such as ankle dorsiflexion. To improve this, methods such as proprioceptive neuromuscular facilitation (PNF), eccentric exercises and electrical stimulation (NMES) can be used. Objective: To compare the effectiveness of a PNF program with one of eccentric exercise plus NMES in the weight bearing lunge, lateral step down and drop jump test in amateur paddle tennis players. Methods: Pilot randomized clinical trial involving 20 male amateur paddle tennis players.

Participants were randomly divided into two groups of ten. One group received a PNF protocol, while the another group was given an Eccentric+ NMES exercise protocol. During the study, range of dorsal ankle flexion (ROMDf) was measured, as well as the vertical jump and lateral step down capacity of the participants.

Inclusion Criteria:

• Be a professional padel player.
• Be over 18 years of age.
• Sign the informed consent to participate in the study.
• Completion of the IPAQ physical activity questionnaire (Annex 1) to assess the level of physical activity of the participants and to ensure that they meet the physical activity level of the participants and to ensure that they meet the requirements for requirements for participation in the study.

Exclusion Criteria:

• Traumatic or musculoskeletal history that may affect the performance of the study exercises, as determined in the exercises of the study.
• A neurological history that may cause impairment in the performance of the exercises.
• Use of orthoses that may generate alterations in the result.
• Difficulty in performing exercises as determined by the Physical Activity Readiness Questionnaire (PAR-Q)
