There is an old saying amongst physios that says: ‘The best exercise is the one that gets done.’

A recent study published in the September issue of the New England Journal of Medicine has put this theory to the test. The authors studied the effect early versus delayed exercise, after an acute muscle strain, has on recovery time for recreational athletes.

Most people by now are aware that early mobilisation/walking within pain limits, after an ankle sprain reduces disability and recovery time. But is this also true for muscle tears?

This study took 50 recreational athletes with an acute injury of the thigh or calf muscles. Participants were divided into two groups. Each group performed the same four-stage exercise programme over a 12-week period. One group started this programme two days after injury and the second group started nine days post injury.

The exercise programme consisted initially of stretches then progressive isometric and dynamic loading followed by functional exercises combined with heavy strength training.

The primary outcome measure was return to full asymptomatic participation in sport after successful completion of a functional screening test.

The interval between severe muscle injury and return to sport was shorter in the early exercise group than in the delayed exercise group. The authors concluded that starting rehabilitation two days after injury rather than waiting for nine days shortened the time from injury to pain-free return to sport by three weeks without any significant increase in the risk of re-injury.

The take home message: Get to your sports physio early after a muscle injury in order to minimise recovery time. For the fitness of you,

Nine in 10 Australians could reduce their risk of heart disease simply by walking as little as 15 minutes more each day, the Heart Foundation said following a new report from the Australian Institute of Health and Welfare (AIHW).

The report looks at the health impact – or ‘burden’ – of a lack of physical activity in terms of years of healthy life lost through living with an illness or injury, or through dying prematurely.

Being inactive has a strong link with heart disease. One-third of the total burden due to physical inactivity in Australia was caused by heart disease.

This figure demonstrates the significance of being active and having a healthy heart.

It is estimated that if the 89 per cent of Australians who fall in the ‘at risk’ (sedentary, low and moderate activity) category did an extra 15 minutes of moderate activity such as brisk walking five days per week, 13 per cent of the potential disease burden due to physical inactivity could be avoided. And by adding 30 minutes of walking or other moderate activity, five days per week, 26 per cent of future disease burden could be avoided, the report stated.

In May, the Federal Government announced that $10 million in funding over two years would be allocated to the Heart Foundation for an initiative to support up to 300,000 Australians to adopt the easy way to better health – regular walking – by 2019.

Shoulder impingement during swimming is largely due to dynamic muscle imbalance and biomechanical faults.

Dynamic muscle imbalances can be addressed by strengthening exercises for the rotator cuff and scapular stabilisers together with stretches for the muscles at the back of the shoulder. One good exercise is to stand facing a wall with your arm raised to shoulder height and elbow straight. Hold a tennis ball to the wall by leaning through your shoulder and pinch your shoulder blades together. Roll the ball in small circles for 15 seconds first clockwise then counter clockwise until you become fatigued or for two minutes.

Biomechanical faults can be addressed by correcting your swim technique. Achieving good symmetrical body rotation through an efficient bilateral breathing pattern helps to avoid shoulder impingement during the catch and pull through phase of the freestyle stroke.

Instead of entering thumb first change your technique to enter with a flat hand or fingertip first. This is made easier by avoiding reaching across your midline. A thumb first entry works the shoulder internal rotators excessively and when multiplied by approximately 3,200 strokes per hour contributes heavily to the muscle imbalance of strong internal rotators and weak external rotators causing shoulder impingement.

Most swimmers pull through with a straight arm or dropped elbow. This loads the shoulder muscles excessively rather than utilising the larger and stronger muscles of the chest and upper back.

Making these simple changes can help you achieve many hours of pain free swimming.

For the fitness of you.
