This is what I see when I tap on the notification.

Subtitles must be useful for anyone with audio deficiencies.

I don't love the computer generated voice-overs but I understand they could make production more efficient than recording human voices.  Of the two, I prefer the first one. 

Leon Jackson I find I can get the heart rate up to a decent target with a 6v3 15Mx30M bi-directional possession game or other similar activity that involves virtually non-stop play and the right dimensions.  Those are fine if I'm just going after endurance. 

But for coordination work, which is the type of physical work I most want to focus on with my players, specialized activities like your preseason exercises are a must. 

The more I can understand how to embed very specific movements that exceptionally build aspects of coordination into a competitive activity without sacrificing quality, I'm all for it.

Des Ryan's work with his staff at Arsenal is an example of a coordination program I'd like to learn the detail of how to implement: https://youtu.be/YdEWvwqZKMg?t=1278

In my experience executing some of the new preseason activities, those that are structured as a race or involve an opposed aspect have been more engaging for players. 

Also, as I understand it from the literature, activities that combine physical development with ball manipulation in which there is repetition with variance baked in is more impactful on development. 

I'd like to continue to see activities that incorporate these two concepts - ideally those that are working well in youth academy setups.  Thank you for all the great new ideas.

One area I want to improve is developing aspects of coordination in U13-U16 players as they go through puberty.

By coordination, I mean psychomotor control of the body, foot speed, agility & change of direction, coordinative aspects of acceleration and deceleration.

Some of the pre-season content includes "SAQ" aspects such as movement through ladders, hurdles, rings, or between cones.  I'm wondering if there is an opportunity to improve this content by leveraging performance coaching experts in this space from youth academies.  I'm thinking of the great work done at academies like Ajax, Arsenal and others in these areas.

This is a bit different than the activities you produce now so I understand it may not fit but wanted to get you thinking about how you might introduce this type of activity for use in on-field sessions or off-field gym/home work.

Short answer is that I use both depending on what I'm trying to do.

If I'm looking for something specific, I search for it.  Filters are a way to help me search if the search logic can't figure out what I want based on the text I use and my past behavior.  Example:  I search for the name of a specific activity when I want to grab its image / PDF.  I also search for an activity related to a specific topic, possibly filtering by number of players or age or level.

If I'm looking for inspiration and I don't have much of a concept of what I'm looking for, then browsing categories makes more sense to me. Example:  I browse the new content category or a specific theme category a lot.

The following outlines search vs. browse user motivation and ways to address both needs : https://www.algolia.com/blog/ecommerce/search-vs-browse-satisfying-user-intent/

I'd keep both but re-visit the format of the browsing menu.

Here are examples of game model themes that my sessions would focus on related to in-possession in the defensive third:

Create an offensive structure, using width & depth, to facilitate advancement of the ball

Use of the Goalkeeper as an outfield player when playing out

Advancing the ball from deep against zero press

Advancing the ball from deep against a 1 press

Advancing the ball from deep against a 2 press

Advancing the ball from deep against a 3 press

Skipping lines when the press becomes too much to play out against

Circulate and probe when defense prevents penetration

Inside each of those are N sub-concepts appropriate for a session.

There are similar types for in-possession further up the field and similar for out-of-possession.

It means I figure out which of your themes apply to which of my themes and look through relevant content to use as activities in my sessions. As I wrote to you before, that's why I end up making 3-5 activities favorites as a way to quickly build a session.

Presently I coach 2009s (U14) group and 2008s (U15)

Each roster is ~18 players

Attendance can be as low as 8 occasionally

With these ages, the training methodology is largely tactical periodization based, meaning each practice is focused on a game model concept and the activities develop some number of related physical attributes, technical skills and tactical concepts.

Example: if the topic is center backs dribbling out of the defensive third to destabilize the opponent's defensive balance, then I might do a session like:

Unopposed dribbling at mannequins before releasing a diagonal ball to waiting players on the opposite side

2v2+1 positional games designed to get players to dribble and release

6v6 small sided games in a 3 zone field with rules designed to get the players to dribble into the next zone or release as they get close

8v6 or 10v8 phase of play working on isolating a center back on the ball who can dribble forward out of the 18 yard box on a goal kick or transition to attack

Curriculum Topic(s) of the Session (I focus on 1 topic per session)

Number of player range the session's activities work for

Age range session is appropriate for

Level of skill the session is appropriate for

Session Length

Session's activities ideally build from unopposed/individual focus to semi-opposed / fully-opposed small group focus to fully opposed larger team focus.

Example:

Unopposed passing pattern (1 or more instances side by side)

Rondo / Positional Game (1 or more instances side by side)

Small Sided Game (1 or more instances side by side)

Functional Practice / Phase of Play

On the computer I'm reviewing the video, taking notes and saving sessions of interest. On the mobile device I'm verifying my understanding while I set up or execute the session's activities.

Session ideally has a summary screen/pdf of just the activities' diagrams or links to each of the activity's diagrams at the beginning for easy reference before containing the details of each activity in video / pdf format.
