Proprioceptive training

I read this article and found it interesting:

Irregular and unpredictable surfaces often found on the trails can lead to ankle injury. Ankle instability can be prevented through the improvement of joint sensation, known as proprioception. Proprioception plays a key role in all activities, especially trail running, where the environment is open and running surfaces uneven. Current research suggests instability training has numerous benefits for your body and can significantly reduce the occurrence of ankle sprains.

Three methods and corresponding benefits of instability training are provided below and are sure to keep you continually active and less injury prone.

A recent study found that home-based proprioceptive training was significantly effective in preventing the recurrence of ankle sprains.

1. Training on uneven surfaces

Running on uneven surfaces increases the demand for stability. Your body meets this demand by using proprioception. The input for the body’s periphery that allows for this sensation to occur comes from tiny mechanoreceptors in muscles and ligaments, and receptors in the sole of the foot, which tell the body how fast and at what tension they are contracting or being stressed. Research has demonstrated that training these mechanoreceptors dynamically while trail running, running on sand, or barefoot on grass, will allow for more efficient sensory input and better performance.

2. Home-based proprioceptiptiptive training

A recent randomized study performed in Denmark and published in the British Medical Journal found that home-based proprioceptive training performed for twelve weeks was significantly effective in preventing the recurrence of ankle sprains. Increasing stability in joints such as your ankle can even refine your muscle reflex capabilities on uneven surfaces and decrease your chance of acute injury such as a joint sprain. This muscle reflex breakthrough, quantified by German biomechanists of the University of Münster, along with previously stated findings, concludes home-based proprioceptive and stability training will have an impact in improving runners’ trail performance, as well as decreasing injury.

Home-based proprioceptive training exercises
Short Foot Exercise
While standing barefoot, pretend you are at the beach and attempt to “draw sand” under the arch of your foot. This technique is a specific way to increase the proprioceptive influence by stimulating the receptors on the soles of the feet. Repeat the movement six to ten times.


One-Legged Rocker Board Perch
Perform exercise statically (standing as still as possible) with rocker board positioned to sway side to side, or forwards to backwards. In both positions make sure the axis of board tilt is directly below your ankle joints, as this joint will support your entire body. Stand with one leg at a time on the board with your body upright, hips and knees very slightly bent (similar to skiing), and try not to look down for increased difficulty. Start with a goal of thirty seconds in a stable perch per leg, and practice each leg (even if one is more proficient), alternating side to side, three times per exercise session. Close eyes to increase the demand for stability.





BOSU-Ball Lunges
Start with your BOSU ball in a stable position against a wall. Place the heel of your forward foot touching the centre of the ball with its flat side facing down. Your forward and rear knees should reach but not exceed ninety degrees during the test repetition or during your set. Now, facing the ball, lunge forward with your lead leg, focusing on your hips and ankle joints and staying as stable as possible. Perform alternating, slow lunges, making sure you push down through your lead heel on the way up on each repetition. This is a dynamic (movement) exercise but is only effective if performed slowly, focusing on decreasing body sway, and increasing body control. Perform twelve lunges with each leg and three to four sets each session.



3. Closing eyes to add difficiculty and further adaptatiation

Closing your eyes to increase stability components in your home and gym training program was recently proven effective by Australian strength and conditioning specialists examining postural sway in athletes with functional ankle instability. The research suggests closing your eyes while performing static proprioceptive training will increase the difficulty of the movement and improve joint proprioception. This technique will add difficulty for elite athletes, as well as beginners who are progressing quickly. There are many inputs that help provide information on balance, such as the inner-ear equilibrium, proprioceptors, and vision. Removing one of these inputs will cause the others to work harder and adapt. Closing the eyes is a great way to force increased reliance on the sensation an individual is attempting to improve.

Gold Standard 100% Whey

Although this is product is more geared toward body builders, I believe that it helps recovery from long or hard training runs where the microfibre muscles require repair. I drink 1-2 scoops of this 5-6 times a week. I like the chocolate mint; the rest is not tasty. Check out more information about why protein: http://www.bodybuilding.com/store/whey.html

HKMP 4X Country + Road Race [0:47:35]

The 4th Shatin Mixed Terrain Race was held on Apr 25 (Sun) starting at 8:30am at the Siu Lek Yuen Village Car Park; distance is around 9km.


First and foremost: This race puts me over 1,007km since I started keeping stats.

At the starting line, all you could see was a big steep hilly road. Well, luckily the weather was great and cool especially for Hong Kong. I have to tell you I was surprised how fast the runners went out because I myself was under 5 minutes for around 100m elevation. I know the elevation say 216; but I don't believe it. I looked at google map and believe that more.

This was all steps going up and up and up. I don't really like to stop running and walk; but this race is a must. You wonder if you are in shape? Well, try this course and you'll realize what your body can handle. For me, I thought the 2 peak hike/run last 2 weekends were enough. I was wrong!

This path turned technically difficult because now it's not steps but you are running half of it downhill like leapfrog. I remember parts of it being dirt trails; flashback 20years when I did cross country.

The rest of the race was all flat; similar to Tolo 5k. I was happy with this pace especially after the brutal first 3k, but some girl just whizzed me by 200m ;( before the end. Good for her!

Summary 0:47:36 8:19 836 925
If you are planning to run or hike the Oxfam Trailwalker in November, Moontrekker in October, or Lantau 2 Peaks 20k race in October; then this race was a little taste of hill race running/hiking/walking.
