One of the problems with this thread is making the connection between plyometrics and drills.
Plyometrics have been proven to aide distance running performance. There is research that shows this. Now, if you can answer the questions of how and why then you can make the connection to drills.
Plyometrics is a coupling of an eccentric and concentric muscle action. If a concentric muscle action is preceeded by an eccentric muscle action it creates more force. More force = more speed. The shorter the transition time between eccentric and concentric action the great the force produced.
Test 1: Jump up without first dipping down...if you even can.
Test 2: Jump up while first taking a big dip downward to produce the eccentric-concentric coupling.
You will jump higher on Test 2.
As you continue to jump over the course of weeks your transition time will shorten and your jump will be higher.
Now, videotape yourself doing high knees and butt kicks, and all other sorts of drills. Look for eccentric action. Watch how one motion leads into the next.
Test 1: Stand. Do a high knee without first flexing your hips/knee.
Test 2: Now do a high knee while first flexing your hips/knee.
Far more effective on Test 2...:)
Drills are a lead into Plyometrics. They are an easier version of Plyometrics. For runners putting in 100 miles a week they may be the ONLY version of Plyometrics.
Jay has it right here:
"Underlying this thread is a common theme/point of contention on LR - what should you spend your time doing? My two cents: create more time in your day, allowing you to do more - more easy running, more fast running, more medium running, more active isolated stretching, more ancillary work, more foam rolling, more ice bath, more self message**, more sleep, more hydration and more attention to Nutrient Timing***"
It's all a matter of what you have time for and what you make time for.
