Lately we have been using the Sledbarrow for power training.
When we look at pure power demanding sports like some of the shorter track racing or the mens 100 meter dash we can essentially break it down into 2 segments.
Segment 1) The acceleration is where the PEAK power output happens. We only see a peak value here lasting maybe 3-5 seconds. Anything beyond that and there is already a drop off.
Segment 2) The maintaining of momentum speaks for itself and is more speed then pure power 8-20 seconds. Its speed because now you are having to fight how quick you can coordinate that power output. Anything longer and you’re likely moving onto training your MAX power FOR (duration or distance). We can still do power drills lasting up to 2 mins but thats 2 min power rather then our true peak value, which again… happens in the acceleration.
Training the acceleration helps for POWER increase, our starts, coordination, engaging more muscle groups, reaction times etc.
Not all the details in this post although hopefully something to get you thinking about how you are scheduling your intervals and strength training, remember quality over quantity always.
