Acute Responses to a Potentiation Warm-up Protocol in Female Football Players.

Acute Responses to a Potentiation Warm-up Protocol on Sprint and Change of Direction in Female Football Players: a Randomized Controlled Study

This study aims to determine if the performance of female football players is affected after exposure to a potentiation protocol. It is hypothesized that performance in the selected physical tests will improve significantly and meaningfully after performing the chosen potentiation protocol compared to the control group's warm-up.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Experimental group; Potentiation warm-up protocol with jumps combined with sprints with change of direction.	Other: Potentiation warm-up protocol; The intervention protocol consisted of i) 1st set - six hurdle jumps, with a distance of 70 cm between each, followed by a 15-m sprint with COD; (ii) 2nd set - six lateral hurdle jumps (three to the left and three to the right) followed by a 10-m sprint with COD; (iii) 3rd set - six bouncy strides, followed by a 15-m sprint with COD; (iv) 4th set - six broad jumps followed by a 10-m sprint with COD. All COD circuits had different configurations, changing the sprint distance and the angle of the COD curve. All repetitions and sets were separated by 90-second recovery intervals, and each set was performed three times.
Active Comparator: Control group; Usual warm-up exercises as previously used by the whole team.	Other: Usual warm-up protocol; The usual warm-up consisted of (i) The first phase included dynamic stretching and drills to increase body temperature. This phase lasted 5-min and included slow jogging, light skipping, and dynamic stretches for hip flexors, glutes, quads, hamstrings, abductors, gastrocnemius and lower limb joints. (ii) The second phase was composed of exercises that intended to mimic specific movements of the football match, both with and without ball possession. This phase lasted 15 minutes and included exercises with and without possession of the ball, such as acceleration, COD, jumping over hurdles, and playful games with ball possession. In this group, the players only rested in a slow jog when they moved from the first to the second phase.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Agility T-test	Used to determine speed with directional changes such as forward sprinting, left and right side shuffling.	First moment: beginning of the first training session; Second moment: at the end of the third week, after the fourth protocol session had been completed.
40-m sprint test	After a 5 s countdown, the participants ran forward following the route marked by cones, one at 0m indicating the start place and the other at 40m indicating the finish place. Participants started the test from a standing start position with the front foot approximately 2 cm behind the first cone.	First moment: beginning of the first training session; Second moment: at the end of the third week, after the fourth protocol session had been completed.
