Contrast Training: How it Works, and How to Use It for Impressive Gains

I'm gonna let you in on a little training secret: it's called contrast training. It's used by elite athletes to improve power output, and the results are pretty impressive. Contrast training, also known as PAP (post activation potentiation), is the pairing of heavy strength exercises and explosive or plyometric exercises. If you want to get the most out of your training, PAP is the way to go.

Try contrast training, and you'll learn to levitate like this dude.

PAP is especially useful for athletes looking to enhance power output. Jumpers, weightlifters, sprinters, and shot putters are a few such athletes who can reap big benefits from this type of training. The benefits are not just limited to elite athletes, however, and can be used safely for intermediate lifters (with 2+ years of training experience).

In essence, contrast training is exciting the nervous system, and improving motor unit recruitment acutely. The more fibers activated on any given movement, the greater the benefit. To quote Roxanne Horwath and Len Kravitz (and no, not the "Fly Away" Lenny Kravitz), "The greater the muscle activation, the greater the duration of calcium ions in the muscle cell environment (referred to as sarcoplasm) and the greater the phosphorylation of the myosin light chain protein (Rixon, Lamont, Bemden, 2007). As a result, faster contraction rates and faster rates of tension develop."

One study done by Chatzopoulos Et. Al. found that heavy resistance training helped acutely improve 10 and 30 meter sprinting times. The sprints were performed after a 5 minute window of resistance training. The participants (young male athletes between the ages of 18-23) performed 10 single repetitions at 90% of their 1 repetition maximum back squat. After only 3 minutes of rest, however, the sprinting times did not increase. It is important to mention that adequate rest seems to be a very important factor here.

Here's a great list of the benefits of PAP, in the words of Bret Contreras:

1. Short-term enhancement – May increased neuromuscular performance in an actual competitive event through PAP
2. Chronic adaptation – May increase training effect using PAP in training which would result in increased Rate of Force Development (RFD)
3. Increased workout density – Combined training allows for more activity with less actual resting time which is critical if total workout time is limited
4. Increased dynamic transfer – By combining biomechanically similar activities athletes may groove more efficient neural patterns by learning to perform the lift in a manner more specific to the athletic activity
5. Increased work capacity – By increasing workout density athletes will increase their work capacity which is characterized by high levels of average power output over an interval (which I call power endurance)

Now that you get the gist for how it works, you may be wondering how you can use it and reap the benefits. Like I said, we want to pair heavy lifting with fast, explosive movements. You want to wait about 30 seconds after the strength movement to execute the explosive, plyometric movement. Rest for about 3 minutes or longer in between sets. The following list provides some pairing options for strength and power movements.

• Bench presses: Standing chest passes, supine chest passes, clapping push-ups, and push-ups to plates
• Strict/weighted pull-ups: Ball slams, clapping pull-ups (advanced), and overhead medicine ball passes
• Deadlifts: Broad jumps, 10-50 m sprints, explosive cable pull-throughs, banded kettlebell swings, and power kettlebell swings
• Squats: Jumping squats, depth jumps, hurdle jumps, jumping lunges

One thing to remember is that you want to keep total volume (reps per session) low. We're not trying to accumulate 100 reps, or anything crazy. This is about intensity, not volume. I'd suggest doing no more than 5 reps of each movement, and 5-6 sets should be enough!

If you're looking for a new way to spice up your strength training routine, contrast training may be just what you need!
