About

FIET

Read full description

The FIET was developed by Barbero et al. with the aim to test Football and Futsal players' ability to deal with high-intensity intermittent exercise. The test protocol was a consequence of match and time-motion analysis to support the logical validity of the FIET. The FIET consists of shuttle-running bouts of 45 m (i.e., 3 × 15 m) performed at progressive speeds until exhaustion dictated by prerecorded audio cues. Every 45-m, subjects are allowed to actively rest for 10 seconds. After each 8 × 45 m, bout players passively rest for 30 seconds before continuing. The starting speed is set at 9 km·h−1, and speed increments during the first 9 × 45-m bouts are of 0.33 km−1, successively shifting to 0.20 km·h−1 every 45 m until exhaustion.

PLEASE NOTE: This app is only available to current Tekkerz players who are registered in our program. The Tekkerz Player Development Platform provides any player aged 5+ years of age with a structured and interactive approach to enhance their football skills and ball mastery. Consisting of approximately 180 videos separated into 12 unique levels, our skills cover the most important foundation football skills at Level 1 all the way up to the most challenging and creative football skills at Level 12. Starting from Level 1, players and parents can watch a video with explanation of each skill, then practice at home or outside, and when ready, record themselves completing the skill. The video can be simply edited and uploaded onto the platform, for one of our coaches to then provide feedback on the player’s performance. Coaches aim to provide feedback within a reasonable period of time. The player’s dashboard records the coach’s feedback, indicating if the skill was successful or requires further work, and therefore allowing players and parents to either continue onto the next skill or review the feedback, practice and upload again. Once all the skills are completed within a level, players and parents then get access to the next level. Players also have the opportunity to compete with players their age by reviewing progress through league tables based on the successful completion of skills as well as being recognised as outstanding performers depending on the number of skills completed each week.

Verdict

The call

The clearest difference is ads: Tekkerz at none against FIET's shown. Tekkerz also leads on device support (3 vs 1) and iOS requirement (15.1 vs 18.0). FIET's advantage is update cadence (every 9 months vs every 22 months). On price and in-app purchases there is nothing between them.
