Endurance Test App

Overview

The YoYo Endurance app is a tool for football and cricket coaches to create, conduct, and manage Yo-Yo endurance tests, replacing manual, paper-based workflows with a simple, mobile-first experience.

The problem

Coaches in Europe are not being able to enter the yo-yo test results fast and easy. Coaches are writing down the test results on a physical piece of paper and then transferring the same data in another web application, making it very time consuming. Not being able to achieve maximum productivity.

Goal

Design a tool that lets coaches quickly and accurately capture Yo-Yo test results on the field, structure them for easy comparison across athletes and sessions, and manage tests end-to-end, creating, editing, and sharing results with minimal friction.

Competitive Analysis

To understand more about this field and how other products make it work, we try to go through the existing applications in the market and comprehend the experience. Out of all those, I tested out 4 different kinds of beep / bleep / yoyo test mobile applications.

1

As a coach, I want to be able to create a new Yo-Yo test and assign athletes to the test.

2

As a coach, I want to be able to start a Yo- Yo test and assign athletes test results while they are running. This will make sure that test results are added faster to the system, so the atheletes can see their results.

3

As a coach, I want to be able to edit test results for an Athlete in a specific Yo-Yo test. This way I can fix a mistake.

4

As a coach, I want to be able to see all my test sorted with the newest one first.

5

As a coach, I want to be able to see details about a specific test.

6

As a coach, I want to be able to delete a specific Yo-Yo test.
