Effect of 8 Weeks of Functional and Traditional Resistance Training on Range-of-motion, Dynamic Balance, Technical Skills, Change of Directions, Linear Sprint, and Jump Performance in U-16 Norwegian Young Sub-elite Soccer Players

Study Overview
=================
Brief Summary
-----------------
To investigate how Norwegian youth football players' physical and elementary football skills are affected after an 8-12-week training period using the Functional Football Performance system or football performance.

Eligibility Criteria
-----------------
Inclusion Criteria: Footballers aged 14 to 16 years old playing in the Norwegian G16 1. Division. Experience of at least three years playing football. Minimum seven out of ten on Tegner´s activity scale. The participants must be highly motivated for the project, which will be measured using the - Likard scale. Eight out of ten is expected (The participant will be anonymous in their registration). Exclusion Criteria: Illness or injury within the last three months has kept the participant outside of football.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention<br>This group will use a functional training system developed specifically for football players to improve their physical strength and movement abilities on the field. | Other: Experimental, comparator and control<br>* To quantify the effect of a strength intervention for footballers on improved range of motion, balance, speed, jump height, and technical football skills compared to a training group from the Danish football strength and conditioning concept Fodboldperformance and a control group.<br>|
| Active Comparator: Positive control<br>This group will use general strength exercises with the purpose of improving physical strength. | Other: Experimental, comparator and control<br>* To quantify the effect of a strength intervention for footballers on improved range of motion, balance, speed, jump height, and technical football skills compared to a training group from the Danish football strength and conditioning concept Fodboldperformance and a control group.<br>|
| No Intervention: Negative control<br>Control group A group that is not treated | |
