@Jonathan Miller are you saying athlete B is just going through the motions while athlete A is maximising training adaptions? --> Athlete B in the example is just going through the motions. Completing the prescription, but not maximizing the adaptation. Also, from what I understand, as coaches, we should put a lot of effort into building the right cues to help build intended outcomes from training? --> I would agree with this statement 100%. if we are training an athlete with a back squat 5x5@70%, the intention should always be to have “max concentric intent”? --> short answer, generally yes. Longer answer is that it depends on what YOUR intention is when prescribing the 5x5 back squat @ 70% Examples: • Building absolute strength? maximal concentric intent increases adaptation (see the studies I referenced in the article) • Want to build strength that transfers? maximal concentric intent results in better speed and power adaptations than low intent (again see the studies). • Need to improve specific positions / posture / breathing / rehab / return to play? tempo work, pauses, or slower concentric phases may be valuable here. From my own training: I'm rehabbing a minor pec strain from bench press - my first phase was yielding ISO's, then an Eccentric-ISO coupling, then chains (set to off load the bottom range of the movement), then full reps @3030 tempo. My pec is at the point that it will tolerate up to 70% of 1RM with slow concentric speeds but coupling a rapid stretch-shortening cycle in the "turn-around" at the bottom of the rep still causes pain. A deeper way to think about this: Yielding ISO's --> strengthen positions & tendons Overcoming ISO's --> improve nervous system drive Slow Eccentrics --> build control, develop load tolerance Fast Eccentrics --> supramaxial loading tolerance (either with things like depth landings OR eccentric hooks) Slow Concentric --> increase TUT, create fatigue, tissue remodeling High Intent Concentric --> maximal strength gain / transfer to sport
