Incidental exercise describes the physical activity you can fit into your day when you are not working hard in the gym. Modern-day living has become about convenience and completing tasks with as little effort as possible. With advances in technologies such as dryers, ROBO Vacs, elevators, escalators, and even dishwashers it is easy to see how this culture of inactive living has developed and easily been accepted. 
Time spent sitting has been linked to increased health risks for children and adults, even for those who are physically active. According to the Australian Heart Foundation the average Australian adult spends more than 15hours a day sitting. It’s possible to break free of these physically inactive habits and not become a victim of accidental weight gain. Here are some easy ways to increase your incidentals this Christmas period

1. Don’t dawdle; beat the crowds of Christmas shoppers: Walking with purpose will increase heart rate, engage your glutes, upper body and core. Not to mention you might just beat everyone to that last Christmas ham.  
2. Wash your car by hand; inside and out! It’s a mini workout.  
3. Park further away and walk; Sick of not finding a park close to kmart? Use it to your advantage. Park further away, get a park easily and increase your incidentals.  
4. Reduce your sitting time by standing; Think it sounds easy? It is! Try reading the family newsletters or watching your favourite TV show while standing.
5. Don’t use the clothes dryer; Utilize the sun in SUNshine Coast and hang out your washing to dry. Not only will you be increasing your incidentals, you’ll be saving the environment and your money on electricity 
6. Take advantage of ads; Love to watch Christmas movies but hate the ad breaks? Make the advertisements worth your time and pump out some squats and push ups during the movie break. No ads? How about repaying the sitting debt by pumping out a few squats or push ups after the movie?

Osteoarthritis is a very common disease and is the most common cause of difficulties with mobility and disability in older people. It is also common in younger and middle-aged people. Approximately 5% of people between 35 and 54 years of age have osteoarthritis. Many of these people have injured their joint earlier in life. Approximately 30% of the population between 50 and 70 years of age have problems related to osteoarthritis and the percentage increases in older age groups.

Osteoarthritis affects the whole joint, but most of all it affects the articular cartilage (the cartilage covering the ends of the bones). This articular cartilage becomes thin and fragile. This can be due to healthy cartilage being exposed to heavy loads over a long period of time (for example, very heavy labour over several years) or unhealthy cartilage that for some reason cannot handle normal loads.

You may have heard osteoarthritis described as ‘wear and tear’ of the joint. This statement is incorrect because loads are still needed to keep cartilage healthy. In a healthy joint, there is a balance between the regeneration and degeneration of cartilage. Osteoarthritis occurs when there is more degeneration (breakdown) than regeneration of cartilage. This can cause cartilage to thin, crack, and maybe disappear. However, cartilage needs a certain amount of load to regenerate. This is why healthy loads need to be applied on joints for cartilage recovery.

Currently, there is no known way of curing cartilage loss. Treatment is used to reduce symptoms and improve function of the joint. Learning about osteoarthritis is an important part of the treatment. Special exercises can be done to relieve pain and boost joint function. When function improves, the next step is to get more active. Being physically active can help maintain weight loss and improve overall health. People who have osteoarthritis should do these things as early as possible.

Exercising has added benefit for people with osteoarthritis. Nutrients are pumped in and out of the cartilage when it is loaded and unloaded. This promotes growth and reformation of the cartilage, boosting its strength. Exercising will have your joints moving through their range of motion. This will make it easier to do everyday things you used to have trouble with (putting on socks, climbing stairs, getting in and out of the car). Exercise helps build stronger muscles, which helps make daily activities easier. Exercising will train your coordination - the ability to use the right muscles at the right time with the right amount of force. This will make it easier to control movements like walking on uneven ground.

Exercise is essential for knee osteoarthritis but currently few Australians with osteoarthritis participate in exercise despite its proven benefits.  At Intune Sports and Physio we will soon be launching a program called GLA:D® (Good Life with Arthritis: Denmark). GLA:DTM Australia is an education and exercise program developed by researchers in Denmark for people with hip or knee osteoarthritis symptoms. GLA:DTM Australia is a program for all individuals who experience any hip and/or knee osteoarthritis symptoms regardless of severity.

The program includes two education sessions and twelve group exercise sessions over an eight-week period.  The program has been successfully run in Denmark, Canada, China and most recently here in Australia. Research from the GLA:D® program in Denmark found symptom progression reduces by 32%. Other outcomes include less pain, reduced use of joint related painkillers and increased levels of physical activity twelve months after starting the program.

If you or someone you know may be interested in the GLA:DTM Australia  program, come along to a free information and education session on at 11am on Thursday 21st February at our Birtinya facility. For more information and to book a place, contact Intune Sports and Physio on 5493 1999.

I’m often asked as an exercise physiologist and coach how an athlete should graduate back into training after a break, or even worse, I see the mistakes many athletes make. For many triathletes or endurance athletes in Australia, June means a return to training and putting down their first block of training for the upcoming season. For this reason I thought I’d put some insight into how you can ensure the first block of your 2018-19 season is your best, and leaves you ready to handle the increased demands of your subsequent training.
Traditionally we see many endurance athletes avoid any intensity during their first block of training and instead focus on low intensity aerobic work in training Zones 1-2. In general this can be an ok plan as the risk for injury is less at lower intensity, however there are many physiological and strength benefits you miss out on compared to if you included some slightly higher tempo or sweet spot training just below threshold.
As you can see in the table below, zone 2 training does have a large variety of physiological benefits such as increased mitochondria density, increased lactate threshold, increased muscle glycogen storage and inter-conversion of fast twitch type IIb to type IIa muscle fibres (type IIa fibres are more aerobic than type IIb so more beneficial for endurance athletes). However, as you can also see the expected physiological adaptations gained with Zone 2 training is far inferior than Tempo or Sweet Spot training.
The other issue with sticking to just Zone 1 and 2 training, which is highly applicable to running, is that at higher speeds there’s also a higher musculoskeletal requirement which we can use to our advantage. Although at high volumes increased speed can be detrimental if you get the dosage wrong, including higher Tempo or Sweet Spot training can aid towards strength development and enhancing movement kinematics. Together this also allows you to transition faster into future training blocks where a focus will include more race pace efforts, intervals, Fartlek or speed work.
So why do so many athletes still train in Zone 1 and 2? Well the issue is if we train all the time at high intensities, although we might gain superior physiological benefits, the risk for injury increases. However, if we carefully calculate and plan sessions out and combine multiple intensity training throughout the season we can minimise risk across an entire season whilst maximising training adaptations from block 1.


So how should you plan your base? The first thing to do is to start working back from your season goals which will determine what the physiological requirements required to achieve them are. For example, if your goal is to run sub 40min for 10km, we know that the body will need not only be physiologically capable of handling 24sec/100m pace for 10km, but also strong enough to handle both the race and training demands required. One simple way which I recommend is to start including run throughs at the end of easier or zone 2 runs from your first block of training and then increase these into the main set of your sessions. For example, you may want to include a session early on in block 1 such as:

10min build,
20min zone 2 finishing with 4 x 100m run throughs at 10km goal race pace.

What this will do is condition your body by the end of your first block of training to withstand higher reps or longer intervals at race pace which will no doubt become a focus of future training blocks session. In essence, you’re starting to train your body from day one to become accustomed to the training and racing demands it will be required to handle through a controlled and calculated way which will minimise future injury risk as your transition from one training phase or block to the next.
Other sessions that can be included in training block 1 would be your Tempo and Sweetspot sessions at least once per week. An example for this would be starting off by including 2 x 5min @ Tempo/Sweetspot with 2min recovery and progressing the total time spent at the higher intensity as your training progresses. By the end of block 2 I usually like to have athletes capable of handling either 30min or 2 x 20min at tempo-sweet spot pace as this will really start to maximise improving lactate threshold, increased glycogen storage and increased mitochondria density which will become vitally important as you progress through your training phases and into more high intensity work.
​
As with all training, it’s best to consult with an expert coach and always remember that a single session won’t make your season as fitness is the sum of the total completed training.

After a knee injury, recovering the functional performance and strength of the lower extremity is an important goal for rehabilitation and recovery. Some recent studies have highlighted the importance of addressing any strength deficits after knee injury or bout of knee pain to possibly prevent the development of early degenerative changes in the knee joint, and improve the knee related quality of life measures in the future.

In a study of ACL reconstructed patients by Culvenor et al (2016), those that could do at least 22 single leg rises had better knee-related quality of life at one and three years post-op than those that couldn’t do 22 repetitions. When we talk about knee-related quality of life in this way, it is a subjective measure of knee confidence, modification of lifestyle, awareness of knee symptoms and the general difficulty because of the knee. 

So the study would suggest that if you were able to perform more than 22 single leg rises now, then you have a much reduced chance of struggling with those particular measures in one year and again in three years time. It may also be important to have functionally strong legs to combat the onset of knee osteoarthritis.

​In another study of ACL injured people, Koos eta al concluded that a reduced functional performance in the lower extremity (inability to do 22 single leg rises) might predict the development of radiographic knee osteoarthritis in the future.

But what if you haven’t suffered a significant knee injury like an ACL reconstruction? Although these studies are directed at ACL patients, the ability to perform single leg squats can improve physical performance in all aspects of life for everyone.​
