Is there a sport that doesn’t require both?
Is there a sport where the amount of one or the other doesn’t depend on the current skill level, or whether the movement is new to player?
Is there a sport where skills aren’t first built in isolated training and then honed under pressure and in competition?
‘But, Ronaldo was created in the opposed training environment of street soccer!’
Has anyone asked him if he ever worked on new moves on his own, at home or on the sideline waiting for next, before trying them in out against others?
Here’s what I notice about those on either side of the debate.
Advocates of opposed training deal primarily with players who develop 95% of their skills away from training, at home or in pickup. Out of sight, out of mind. Since they don’t see how much effort these players put into those skills, they think all players have that level of ability or they think they got to that level of ability with their opposed team training environment and discount the effort the players do on their own.
The opposed training advocates also tend to straw man the “isolated” side of the debate as if the other side believes isolated training is the only thing needed. I haven’t seen anyone who believes that. Rather, they support progression from isolated to competition.
Those who advocate isolated training typically work with players that do not work on their own or play pickup to develop their skills and need a healthy foundation of isolated training to build muscle memory before working up to using in competition.
