Exercise Physiology for running performance

Running is an extremely popular form of exercise with almost no cost and fantastic physical and mental benefits. I’m sure we’ve all met runners who are almost obsessive about their running and are like a bear with a sore head when they can’t run. We see lots of runners at Central Performance, from office workers who run a couple of times a week for the health benefits to our elite running group coached by physio and track coach Ben Liddy.

One thing most of our runners have in common is that they would like to run a little better. Whether that’s reducing aches and pains they feel when running, improving their City2Surf time or lowering their 1,500m PB everyone wants to improve somehow. An often-overlooked way to improve running performance is to include some weight training into your training. The classic opinion was the weight training made you heavy and slow however there is a lot of good research that shows that weight training can significantly improve endurance, running performance and running economy.

It used to be thought that to improve performance in endurance sports like running that it was more beneficial to use a light weight for lots of repetitions when performing weight training. The theory was that it better replicated how the muscle worked when running and therefore it would lead to greater improvements in running performance. We now know that low repetition, heavy weight training and plyometric training is better for improving running performance and economy. This might seem counter intuitive but there are some good reasons for why that is the case.

First of all, heavy weight training and plyometric training both improve what is called Rate of Force Development (RFD). RFD means how quickly a muscle can produce force, the higher the RFD the quicker a muscle is able to produce force. A high RFD is important when running because ground contact time with each stride is so short. If you are able to increase the RFD of the muscles in the legs then you are able to decrease your ground contact time and increase your running cadence. Increasing your running cadence improves your running economy, making you a more efficient runner.

Secondly, a stronger muscle means that each stride requires relatively less effort from the muscles in your leg. For example, the soleus muscle in the calf has to deal with between 6-8 times body weight with each stride. That is an awful lot of force to be dealing with for a sustained period of time. A strong soleus, strengthened with the help of weight training, will be better able to handle 6-8 times body weight for a 800m race, 5km fun run or full marathon.

Thirdly, heavy weight training and plyometric training help to strengthen and stiffen tendons. A stronger, stiffer tendon is better able to transmit the force produce by the muscles into the movement of bones required for running. Better force transmission by the tendons again improves running economy and efficiency. It also has the added benefit of helping to guard against the development of tendinopathies such as Achilles or hamstring tendinopathy. We see many runners with these injuries and heavy weight training is the starting point for their rehabilitation.

As you can see there are some very good reasons for including heavy weight training and plyometric training to improve your running performance. As simple as two sessions of weight and plyometric training per week can lead to significant improvements in running performance. Below is an example of a simple weight and plyometric training session for runners.


Goblet squat:

The goblet squat is a fantastic way to introduce the squat movement into your training program and it is the first version of the squat we use with our clients. The squat is one of the key movements in weight training programs we develop for runners as it is fantastic for developing quad strength. This is important as the quads take the second most load during running after the calf muscles.


Single leg deadlift:

Another key movement in the weight training programs for our runners, the single leg deadlift is great for developing strength in the hamstrings and muscles of the lateral hip, particularly the glute medius. The glute medius plays an important role in maintain lateral stability of the hip, helping to prevent hip drop and subsequent valgus collapse of the knee when your foot strikes the ground. We also aim to have a mix of double leg and single leg exercises in our programs and the single leg deadlift is one of our favourite single leg exercises.

Bent knee calf raises:

An often overlooked muscle group when weight training, the calf muscles have the highest demand on them of any muscle group when running. As stated earlier, the calf muscles must handle between 6-8 times body weight with each stride. Therefore, it is important to strengthen the muscles of the calf. The bent knee calf raise helps to prioritise loading on the soleus muscle and better replicates the ankle position during running.

Hurdle hops:

Hurdle hops are one of our first plyometric progressions we introduce into our runners programs. It is a great exercise to help develop power on one leg and get our clients used to the landing forces associated with plyometric exercises. With a hurdle hop we emphasise ‘sticking’ the landing which requires our clients to be able to control the landing forces.

Physiotherapy For Low Back Pain Part 2: Treatment For Back Pain

In Part 1 of this blog series on back pain we reviewed the three types of low back pain, plus busted some myths about scans and radiology findings. In this post we will review the way physiotherapists can treat back pain, plus the lay out the best advice on what you should do at home or work to make your recovery as quick as possible. In Part 3 of this series we’ll review things that you can do to reduce your risk of future pain episodes.

As we have discussed in Part 1 there are three main types of back pain. Getting a correct diagnosis for your back pain is an important because it guides your initial treatment.

Physio for Non-Specific Low Back Pain

Physiotherapy treatment for this type of back pain focuses initially on relieving your pain and restoring your range of motion. We need to get you back to doing your normal daily activities as fast as possible, allow you to sleep normally, and be able to do your usual work duties. We use a combination of hands-on (manual) treatment together with structured exercise to increase your joint mobility, plus release muscles that are tight or in spasm.

As well as prescribing the right exercises for you, your physio will also clearly explain do’s and don’ts for you at home and work so that you help your back pain to settle as fast as possible. It has been extensively proven through research that staying active within your comfort levels, avoiding bedrest, and returning to your normal work and daily activities as quickly as possible is by far the best way for you to help your back pain resolve. Using basic medications like Panadol, Neurofen or Voltaren can also be very helpful at this stage.

Once your pain is resolving well your physiotherapist can guide you through a progressive exercise program to fully restore your strength, ensure you are moving correctly, and get you confident in returning to the gym or your usual sporting activities. Completing a supervised strength program with an accredited exercise physiologist is the gold-standard later-stage management program for low back pain, especially if you have already had several episodes of pain or are lacking confidence in returning to your full normal gym or exercise activities. If you prefer, Pilates is also an excellent way to exercise following low back pain.

Physio for Radicular Pain – Commonly Called Sciatica, Nerve Root Pain or a Pinched Nerve

The initial focus for physiotherapy treatment for back pain where a nerve is compressed (or pinched) is to relieve the pressure on the nerve. The degree to which the nerve is pinched or irritated can be gauged by the amount of referred pain that travels down your leg, plus the presence of other neurological symptoms including numbness, pains-and-needles or weakness. Hands-on treatment plus specific exercises are used to relieve these neurological symptoms as quickly as possible, plus medication such as Voltaren can be helpful. You will also be given exercises to do at home by your physio to help you relieve your pain and get moving again.

Once the pressure on your nerve is relieved, the physiotherapy management for radicular or nerve-related low back pain is largely the same as for non-specific low back pain. A combination of hands-on therapy plus structured exercise progression will relieve any remaining pain, restore your movement, and then reactivate your muscles. Staying active within your comfort, returning to work and daily activities as soon as you are able, and avoiding bedrest is strongly shown to be beneficial for this type of back pain.

Once your pain has settled then completing a supervised strength program with one of our physio’s or accredited exercise physiologists will get you fully back to your normal sport, exercise, work and daily activities. Pilates can also be very helpful, if you prefer this style of exercise. Any contributing movement problems that may have contributed to your pain can also be corrected to reduce your chance of future problems.

Physio for Possible Serious Pathology

Serious lumbar (low back) pathology is very rare – present in less than 1% of back pain cases. It includes things like spinal fractures (broken bones), tumors, and some types of infections and inflammatory conditions. During your initial assessment your physio uses specific and effective tools to screen for serious pathology, and they are concerned they will explain their concerns to you and provide you with a referral back to your GP for further investigation.

If You Have Back Pain: See A Physio And Stay Active!

So, now you know the guidelines for how physiotherapists treat the different types of low back pain. A key take-home message for you is that staying active within comfort, avoiding bedrest, and returning to your normal activity as soon as you are able has clearly been shown to be the best way for you to help yourself recover from back pain. Your physio will give you more guidance on this, plus use hands-on techniques and prescribe the most effective exercises for your specific situation to help you recover as fast as possible.

In the next post in this series on how physiotherapists treat low back pain we’ll review things you can do to reduce your risk of future pain episodes. As always, if you have any questions in the mean time please feel free to contact one of our friendly physio’s to see how they can help!

Should We Really Bother Foam Rolling So Much, Really?

For all the jazz around foam-rolling these days it may be surprising to know that the underlying mechanisms are still not well understood and there is a paucity of high-quality and well-designed studies available.

Some of the proposed mechanisms of effect may include:

1. Reflex neural inhibition

2. Increased stretch tolerance

3. Mediating pain-modulatory systems

What we do know is that foam-rolling appears to be effective for producing short-term gains in flexibility without reducing performance. And while the benefits to muscle function have not yet been established, there does seem to be a demonstrable reduction in post-exercise muscle soreness as a result of post-exercise rolling.

So, from the research that we do have, it’s safe to say that foam-rolling is perhaps not the miracle saviour for poor exercises choices or not moving enough that we once thought it was.

Why Should We Train Through A Full Range of Motion?

We’re often asked about the benefits of going through a full range of motion with your strength exercises. Here is why we recommend that you do and what it means for your training.

1. You get a more complete stimulus and development across the full length of the muscle. We know that muscle fibres don’t always run the entire muscle length from origin to insertion. We also know through the specificity principle that strength gains are specific to the joint angles that are trained so it is important to cover as much of the movement arc as you can. A full range of motion allows greater activation of as many fibres as possible and better strength and hypertrophy gains.

2. Technique standardisation. When you go through the same, top to bottom range for each and every rep, you can be sure when you are progressing and not simply changing form to accommodate the load.

3. Length and strength in long positions. Research has been piling high with the benefits of loading in long muscle lengths (such as in the bottom position of a squat or stiff-legged deadlift, pull up, or bench press where you feel the greatest stretch). This enables strength gains specifically in those ‘stretch’ positions where typically we are not able to produce as much force. Loading into lengthening (eccentric loading) also allows greater overload as well as flexibility improvements.

4. Less injury risk. There is a greater dispersal of stress across more joint systems and larger excursions of motion mean that less load is needed to provide an overload. This greatly reduces the likelihood of a training-related injury.

There certainly are circumstances were you might consider reducing range, such as:

1. To provide a greater overload in a particular joint position thereby effecting a specific muscle or group of muscles. Less range means more weight can be used so caution is advised here. This is to be used sparingly and mostly for the advanced lifter only.

2. Specific sport application – half squats have been shown to have carry-over to running and sprinting activities.

For the most part, the bulk of your training should emphasise taking the joint through as much pain-free range as is controllable and the muscle through full stretch to full contraction. It might mean you’re using a little less load however the benefits hugely outway the risks:

  1. Reduced risk of injury which can set your training back
  2. More complete development of a muscle and strength in weak positions.
  3. Consistent technique and clairty of progress.

Should You Be Using A Foam Roller?

Foam rolling is an extremely popular form of self-massage, with a huge number of athletes from almost all sports using it in one way or another as a part of their preparation for either training or competition.
Here at Central Performance, we get a great number of new clients asking about foam rolling, and whether it will be helpful to them not only as a part of their training, but in their everyday injury maintenance. We encourage our clients to utilise the foam rollers in their gym or homes every day, as they are a great way to not only help prepare for exercise, but also recover from it!
Foam rolling is a fantastic tool to use as a part of rehabilitation because they enable you to release tight areas of the body on a daily basis, leading to improved movement and performance. These tissues can be tight due to injury from regular training, or even sustained postures throughout everyday activities e.g. desk-based workers often experience tight hip flexors from having their hips in a constantly flexed position at their desk all day.

Foam rolling is also extremely useful when recovering from exercise. Evidence shows that Delayed Onset of Muscle Soreness (DOMS) is significantly reduced when performed immediately following exercise, and then both 24 and 48 hours on muscle groups that were the main focus of the exercise session. Enhanced recovery leads to a greater level of ability and performance, hence why elite athletes everywhere are using it!

Some of the most common areas we encourage our clients to release through foam rolling are:

 

1. Quads: rolling is very helpful for reducing tightness is your thigh. Runners find this especially useful, and it can help prevent or manage patellofemoral (kneecap or runners knee pain) and quads strains. To do it, lie on your front with a foam roller under one leg and slowly roll up and down the length of your quad.


2. Calf: excellent for runners with tight calves, place a foam roller under one calf and lift off the floor with your hands, rolling up and down the length of your calf.

 


 

3. Lateral (outer) thigh: great for reducing soreness on the outside of the hips or knees, lie on your side with a foam roller under the outside of your leg and roll up and down the length of your thigh.


So if you are feeling a bit tight and sore with running, training at the gym, netball or whatever, give these a try and let us know if you need any help!

Runner’s Knee – Patellofemoral Pain Syndrome


Patellofemoral Pain Syndrome (PFPS) is a common complaint we see here in the clinic. This usually presents as a gradual onset of pain in the front of the knee which is generally vague and difficult to pinpoint. This knee pain usually progressively worsens over time and can interfere with your daily activities and overall function. There can be a number of contributing factors to PFPS and therefore it needs a thorough examination to identify the important factors for each individual patient. Factors such as load management, range of motion, strength and control of the hip, knee, ankle and foot can all play a part in the development of PFPS. It is important then, that we identify the contributors and target these factors with an individualised rehabilitation program. Let’s take a look at these factors in some more depth:


Load Management: As with many injuries we see here at Central Performance, the main contributing factor tends to be a sudden increase in activity (running or loading) e.g. getting back to running after a break but trying to do the same distances you were running before you stopped. Although PFPS often affects runners, it can also occur from other repetitive activities such as stair climbing, hiking or hill running as well as excessive compressive activities such as squatting and kneeling. Key to the successful rehabilitation of PFPS is to manage your load in an appropriate and graded way.

Knee Strength and Lateral Tightness: Research shows that people suffering from PFPS tend to have a weakness in the quadriceps muscles. We also see that the structures (eg the ITB) on the outside of the knee and hip are tight and this affects the position of the patella, pulling it laterally and causing increased wear and tear on the cartilage of the knee due to this sub-optimal tracking.

Rolling in of the knee (“valgus collapse”) commonly causes Patellofemoral Pain in runners.


Hip Strength and Control : A lack of hip strength or control, particularly in the gluteal (“glutes”) muscles to the side of your hips, can result in a rolling inwards of the knee during single leg activities (e.g. walking, running, steps etc). This inward rolling (“valgus collapse”) also pulls the patella outwards, which causes further wear and tear on the under surface of the patella itself and on the contact points of the femur.


Ankle and Foot Factors: Stiffness or restriction of the ankle can transfer excess load up the leg and place more stress through the knee. Similarly, if there is a lack of strength in the calf complex, then this can result in an increase in load through the knee joint in order to compensate. Foot posture has also been linked to PFPS, with those people having flat or “pronated” feet more likely to present with patellofemoral pain.

As you can see, managing Patellofemoral Pain Syndrome is as complex as it is to spell it! It requires a thorough assessment and an individualised rehabilitation program addressing the factors that are specific to you and your pain experience – there is no “one size fits all” treatment recipe. So if you are experiencing anterior knee pain our talented team of physio’s can help!

Effective Exercise Treatment For Hamstring Strains

Strength, Flexibility and Running Are Key Elements of Hamstring Rehab Programs

Hamstring injuries can be tricky, and proper treatment is a definite must before testing them out again on the sporting field. Hamstring injuries are among the most common we see here in the clinic, and we believe in using a holistic treatment approach encompassing several areas to get those dodgy hamstrings healthy again!

 

The three main treatment avenues we use are: Strength, Flexibility and Running.

1. Strength

1 Leg Barbell DeadliftsStrength is a crucial part of keeping hamstrings healthy, and there are a number of exercises we like to use to increase hamstring strength. We use progressive overload in both hip and knee dominant exercises to ensure maximal strength levels are achieved. Some of these exercises include single leg bridges, Nordic curls, prone hamstring curls, single leg deadlifts and hamstring slider curls. Remember to mix up your exercises and give yourself plenty of rest between sessions.

2. Flexibility

Obviously, flexibility is a massive part of healthy hamstrings, however many people don’t release that flexibility of muscles other than the hamstrings also plays an important part of keeping those hamstrings healthy. Therefore it is important that flexibility components of hamstring rehab programs focus on glute, hip flexor, quadriceps and calf range of motion as well as the hamstrings themselves. Poor range or severe tightness in these muscles are an injury risk factor, so this should be a priority for anyone returning to sport from a hamstring injury.

3. Running

Running can be a difficult part of hamstring rehab, as in many cases it was the mechanism of the injury! It is however an extremely useful tool in hamstring rehabilitation, and once you’re over the initial hesitancy is the trick to getting those hamstrings firing again. Changing up the style of running training you do is key. We use a mix of progressive speed exposures, max speed exposures, change of direction and deceleration training, and again suggest varying the type and intensity of running training you complete.

What To Do To Help Recovery

The four main components that we address when building a high-performance program are mindset, movement, nutrition, and recovery. With this post and the few to follow we are going to look at some things that you can do to influence an often overlooked but vital piece of the performance puzzle, recovery.
First up, here is a general overview.
.
 
 
”Every training element has a point of diminishing returns. Our job (the coach’s job) is to find it shift emphasis and cycle back at the optimal point in time.” ~ Derek Hansen
.
It’s important to understand that physical (and mental) exertion is a stress input that requires a recovery process and ultimately triggers a particular adaptation. Within the training realm, your workout is the stressor event. After a difficult session, there is an alarm reaction in the body caused by working out that results in a mobilising response, creates an inroad to your recovery and an acute performance decline. After this, a rebuilding period is required for the body to build back up to baseline and beyond in order to withstand future training inputs.
 .
The rebuilding or recovery stage is made up of the physiological events that occur between workouts and is helped along by good nutrition, enough sleep and various other activities that we’ll talk more about later.
 .
 If you’ve done enough to recover from your training inroads and adapted to a higher ceiling of resilience, you’ll notice a small increase in performance (faster time, longer distance, heavier weight etc). It can be said then that you’ve completed the cycle and gained a positive adaptation from your training.
You’ve gotten a little better, and so the cycle continues. Apply an appropriate and recoverable stimulus, and repeat.
.
 
Stress + Recovery = Adaptation
…or 
Work + Rest = Success

.
As you can see, improving performance is a delicate balance of measured training and healthy supporting habits to maximise the result of your efforts. Recovery is the necessary bridge between the work that you do and what you get out of it. You don’t progress from simply training alone.
 
.
There are two parts to recovery: Rest and Regeneration.
Rest is an entirely passive strategy, involving a deliberate attempt to minimise planned movement and the mental and emotional duress associated with aiming one’s efforts at a long-term training plan.
Rest is aimed squarely on achieving physical and psychological recharge.
 ….
Regeneration involves active, movement-based strategies used to minimise fatigue, replenish energy systems, encourage tissue healing and function, re-sensitise to the training stimulus, and speed up the recovery process.
.
Some of these strategies include manual therapy, stretching, low-stress aerobic activity, and cold therapies to name a few.
 
We will discuss some of the strategies in the next instalment.
 
Stay tuned…

Should You Be Starting A Pre-season training Program?

Pre- Season training: why is it important?

For many people who play winter sports like football, soccer, AFL, netball and hockey, pre-season training is just around the corner or may have even started already. Completing a whole pre-season program is not only vital for fitness levels and skill practice, it can be a massive component of preventing injuries throughout the season!

Pre-season strength trainingA 2016 study found that elite AFL players who completed <50% of their pre season training were 2x more likely to sustain an in- season injury than those who completed >85%. This isn’t just relevant for AFL though; it’s relevant for all sports at any level.

This is a telling stat, and one that needs to be at the front of all athletes’ minds whilst participating in pre-season training. Even if you’re injured, there is something you can do. Pre-season isn’t just about “getting fit again”, it can be used for rehabbing those niggly injuries still hanging around from last season. The is also lots of research showing that increasing strength can help prevent many common sports injuries including hamstring and adductor (groin)  muscle tears, rotator cuff and other shoulder injuries, shin splints and other sprains and strains.  

Research from the Australian Institute of Sport (AIS) also shows that avoiding rapid spikes in training load helps you avoid injury not only in pre-season, but during the season as well. Going straight in to in-season training and competition loads causes a huge spike in strain through your body and this dramatically increases your risk of injury during the season.

So make the most of your pre-season training. Get yourself to those sessions, and work on everything you can! Remember, the work you do now will pay off come start of season if you make the effort!

Not sure what to do for your pre-season training? Let one of our Strength & Conditioning coaches  or Exercise Physiologists get you on the right program to boost your performance and reduce your risk of injury
