Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is being conducted for a master's dissertation. Our goal is to determine if there are physical performance benefits to performing the FIFA11+ soccer warm-up program in adult female soccer players over an eight week period. This topic has been studied primarily using male soccer players. The performance effects in adult female soccer players is currently unknown.

This warm-up has been shown to reduce non-contact injury rates in soccer players aged \>13. If performance benefits are demonstrated in this study, in addition to the reported injury reduction benefits of the FIFA11+ warm-up, program adherence and player performance could improve.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NON_RANDOMIZED

Intervention Model

PARALLEL

A parallel, two-group, pre-post comparative trial is proposed for this study. Two soccer teams comprise the convenience sample. One team ("Impact") will be allocated to the control group while the other team ("Hearts") are allocated to the intervention group. Participant allocation is premeditated due to Dr. Matt Wentzell's regular paramedical involvement with the "Hearts" and therefore his ability to oversee and administer the intervention warm-up. The control warm-up will be run by the coaching staff of the control group.

Performance pre-testing will be performed by three trained assistants one week after the 2018/2019 soccer season begins. Tests will be performed three times with the best test score being recorded.

Both groups will then complete their assigned warm-up three times per week for eight weeks. Both groups will complete posttesting within three days of the trial period concluding in a fashion identical to that of the pre-testing session.
Primary Study Purpose

SUPPORTIVE_CARE

Blinding Strategy

SINGLE

Outcome Assessors
Participants from both teams will be aware of whether or not they received the intervention warm-up since the intervention warm-up would be a deviation from what each team typically performs for a warm-up.

Investigator, Dr. Matt Wentzell is not blinded to which group is receiving the intervention warm-up since he will be leading the warm-up over the 8-week period.

The three trained assistants will be performing the performance pre- and posttesting. They will be blinded to the group each player has been allocated to.

Any study member that is not blinded will not be performing the pre- and posttesting.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

FIFA11+ / Intervention Group

This group will complete the FIFA11+ warm-up three times per week for eight weeks.

Group Type EXPERIMENTAL

FIFA11+

Intervention Type OTHER

The FIFA11+ has three parts and consist of 15 exercises.

Part 1 consists of active stretching, running and controlled partner contact drills.

Part 2 has three difficulty levels for 6 sets of exercises. The exercises consist of core and leg strength exercises, balance and plyometric drills. The exercises in this section are perhaps the most unique element to the FIFA11+ warm-up, as strength-specific exercises like the Nordic Hamstring Curl are not generally included in soccer warm-ups.

Part 3 consists of higher intensity running drills, compared to those covered in Part 1.

Unlike many soccer warm-ups, the FIFA11+ has been studied rigorously in terms of its injury reduction potential.

Typical Warm-up / Control Group

This group will complete their usual warm-up three times per week for eight weeks

Group Type ACTIVE_COMPARATOR

'Usual' Soccer Warm-up

Intervention Type OTHER

This warm-up is time-matched to the FIFA11+ (approximately 20 minutes) and is considered 'usual' for the team.

This warm-up consists of stretching, running and agility drills, in addition to "small sided" games with a soccer ball, which is not a part of the FIFA11+.

The 'usual' warm-up is decided by the coach with no standardization nor any formal research on its effectiveness in injury reduction or performance enhancement.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Must be a female amateur soccer players on a North Shore Girls Soccer Club Selects A Team
* Must be between the ages of 18 and 45
* Must play a forward, midfield or defender position

Exclusion Criteria

* Mustn't play a goal keeper position. The physical demands of this position is drastically different than all other soccer positions. The training effects from practices and games are unique and may therefore influence the effects the FIFA11+ has on players of this particular positions.
* Mustn't have an illness or injury preventing them from participating in soccer practice, games, and testing procedures. Injury or illness would likely result in poorer physical performance outcomes relative to healthy participants.
* Mustn't miss a physical performance testing session. Pre- and posttest data is required to determine if there are changes in performance metrics in relation to both the intervention and control groups.
* Mustn't be pregnant or of childbearing potential for the duration of the study (10 weeks). The PI and Co-Investigators are not familiar with each participant's reproductive health and history or how pregnancy may affect each participant's response to either the intervention or control group. It is therefore decided that participants that are pregnant or of childbearing potential will be removed from the study.
