Incomplete recoveries, time constraints and perturbations (mini collisions)
Jamie looks at each rep as a learning opportunity where the athlete can gain the experiences of effective and ineffective strategies. When applying these different scenarios, the appropriate amount of variability is an essential component to the skill acquisition process. The goal is to develop high execution variability (process) and low outcome variability (end result stays the same). This is where the concept of repetition without repetition plays a major role in our problem-solving environments. This doesn’t have to be complicated. Simple, slight changes to the athlete’s starting location, initial velocities, size of workspace, number of participants, goal’s location, etc. can create different movement problems and facilitate adaptable solutions.
The problem-solving emphasis (speed or strength) will determine whether Jamie concluded with a plyometric activity or force acceptance drill. Elasticity or the ability to effectively transfer energy underpins all of the different speed, change of direction and agility skills. There’s a misconception that plyometrics have to always be intensive or performed with maximum effort. Jamie has been successful incorporating extensive plyometrics where the focus is being under control, effortless and rhythmic. These are a fantastic tool to teach the athlete to appreciate the importance of the foot, the concept of pre tensioning and build confidence, redirecting forces in different directions (linear, lateral, diagonal & rotational) and shapes (straight & bent-leg). Jamie also takes into consideration the surface, which is often overlooked or ignored when developing elastic strategies. The purpose of manipulating the surface is to change the sensory input and facilitate an appreciation for pre tensioning, foot function and force vectors.
Similar to the previous session (low CNS) Jamie utilized force acceptance drills (altitude landing & depth drop) as an opportunity to stress the importance of how the athlete’s system cannot produce (force production) what it cannot absorb (force acceptance). With the novice or untrained athlete, the eccentric forces will exceed the system’s capability of accepting and re- producing (redirecting), resulting in tissue overload and poor outputs (slower sprints, lower/shorter jumps, delayed changes of direction, etc.). If there’s minimal tissue tolerance, there will be a greater chance of breakdown. Altitude landings and depth drops is a fantastic strength tool for decreasing neural inhibition and gaining an appreciation for the foot. Jamie included different layers of challenges to increase the amount of variability and foster adaptable deceleration (landing) strategies. Also, this can be utilized as a teaching tool and provide the athlete the opportunity to learn how to effectively separate the upper from the lower body. This is a tool that every athlete should have in his/ her movement solution toolbox.
