Here's another AFL-specific study looking at how long you let training activities run based on a umber of factors.
Most of the time we see activities run for too long and the players lose interest,which us coaches see as "a drop in talk" - if there was something interesting to talk about then they would be.
Drop the footy cliches, they're just holding your coaching and your players back from improving in the current form of the game, of which I'll touch on in my next post.
Here were my notes from it:
- 5 behaviors were analysed being disposal frequency, efficiency, pressure, possession time and player movement velocity in an even numbered small sided game and each team scoring at each end of the ground
- There were 10 – 12 players/team on a 90x60m playing area with a minimum activity duration of 4mins
- For each rep, coaches chose teams mostly based on position but had different players in most sessions
- Skill data composes was disposal (kick/hb), type (in/effective), possession time (-/+2secs), physical pressure (within 3m yes/no)
- A kick longer than 40m is effective if kicked to a 50/50 or outnumber advantage for the attacking team
- Kick under 40m are effective if the intended target maintained possession
- There were 4 sequences to describe the skilled behavior during each training activity x disposal frequency (possessions/min), efficiency (%), pressured disposals (%) and disposals under 2secs (%)
- 6 iterations of a training activity were also evaluated resulting in common change point locations between 196 – 252secs (alterations in player behavior) x disposal frequency x 5 – 7/min, 71 – 88% efficiency, 24 – 54% pressured possessions, 8 – 38% possession time, velocity x 120 – 135 meters/min
- All 6 reps totaled 185 skill involvements and 29mins
- Players had reduced aggregate physical/technical performance following periods of peak high intensity in match play during 2nd halves + 2nd half physical activity is influenced by 1st half activity meaning training can be designed more specifically to player activity levels
- Change point for pressure was 124secs probably from fatigue and thus defender's adapting to how they defend (space v player)
- Use change point to identify the moment a behavioral change occurs that signals the end of an activity rather then just going for time, or for a coach intervention and an added perturbation to preserve the metrics above such as number advantage to make it easier/harder for the offensive team
