Weight
for Age
Resistance training isn’t just for gym junkies; it has
a host of benefits, particularly as we grow older, from helping control
diabetes to preventing osteoporosis. Unfortunately resistance or strength
training suffers from something of a low profile, with many people unaware that
muscle strengthening exercises can be good for your health and may even help
you lose weight.
In terms of physiology, resistance training increases
muscle strength by pitting the muscles against a known weight or force. The
muscle cells then adapt to the extra workload by getting bigger (hypertrophy)
and using more nerve cells to help the muscles contract with more efficiency
and power.
Resistance training is most often associated in
people’s minds with the type of training done by body builders (i.e. Arnold
Scwarzenegger) and weight lifting athletes. When training, these athletes lift
heavy weights, a minimal number of times (i.e. 4-8 repetitions). This type of
resistance training generates significant increases in muscle strength / power
and muscle size (hypertrophy), while only obtaining minimal health benefits….but
they will look good on the beach!!
However there is a second type of resistance training
that not only strengthens muscles but also improves their endurance and muscle
tone (i.e. shape), in a manner similar to other forms of exercise such as
walking and swimming. It involves lifting a lighter weight many times (10-15
repetitions minimum) and has been shown to achieve significant health benefits,
by preventing a wide range of medical conditions and chronic diseases.
Benefits of
Resistance Training
-
Increased muscle strength, power, endurance and size
-
Increased bone density and strength
-
Reduced body fat
-
Increased muscle-to-fat ratio
-
Boosted metabolism (i.e. burning more calories when at
rest)
-
Lowered heart rate & blood pressure after exercise
(thought to reduce the risk of hear disease)
- Enhanced performance of everyday tasks
Research shows that resistance training can be a form
of treatment for specific medical conditions that are more likely to affect
middle-aged and older people. It can help, improve or prevent depression,
diabetes, heart disease, weight loss, low back pain, osteoarthritis, falls in
older age, osteoporosis and sleep disorders.
Studies show that resistance training provides
additional, but modest weight loss when combined with aerobic
exercise and a healthy diet, says exercise physiologist Chris Tzar, from the University of NSW Lifestyle Clinic. One in three
adults over the age of 65 experience a fall each year, with hip fractures the
most common resulting outcome, which can seriously affect a person’s ability to
remain independent. Cathy Nall, the current Australian Physiotherapy
Association President, reports that “exercise programs designed by
physiotherapists can help improve strength, balance, endurance, fitness and
bone density, all of which help lessen the chance of falling”.
Resistance training can also help prevent the
development of future problems, given that the older we get, the harder it is
to do simple daily activities like getting out of a chair due to a loss of
strength. However this isn’t inevitable, as it is largely reversible and can be
prevented by doing resistance training.
Getting Started
You don’t have to sign up to expensive gym memberships
or slave at a heavy duty weights machine to do resistance training. It can be
done at home or at the local park, at your own convenience, using your own body
weight, a few lightweight dumbbells and maybe even an additional stretchband. These
could be as simple as squats, lunges, crunches or bicep curls. Depending on
your level of fitness and experience with performing resistance exercises,
these exercises may even be modified i.e. push ups might be modified to doing
in standing against a wall initially.
Prior to you starting, a comprehensive history and
physical examination by one of our sports physiotherapists will ensure that you
are directed and taught appropriate exercises for your experience levels, while
also working you towards your established short and long-term goals. Depending
on any existing medical conditions, the physiotherapist may also direct you to
your general practitioner / sports physician prior to starting, to ensure that
it is safe for you to commence resistance training.
For a beginner you may start with a program of 5
exercises, with each exercise being done in 2-3 sets of 10-15 repetitions. This
would be done 3-4 times per week, with a rest day in between. The rest day
allows the muscles to recover from the physical stress of the exercises
performed, such that they will be ready for the next training session. In order
for the muscles to get stronger, you must fatigue them, and as a general rule
of thumb, the exercises are the correct resistance if you start to feel ‘tired’
at approximately the 8-12th repetition of each exercise. If you can complete
them easily i.e. the muscles are getting stronger, then it is time to
progressively increase the amount or resistance and / or repetitions being
completed, to ensure that the muscles are continuing to be overloaded and
fatigued, and hence made stronger. This
is the most important aspect of any resistance training program, and is called
‘progressive overload’.
Basic
Principles of Resistance Training
- Warm Up / Cool Down: thoroughly to reduce
the risk of injury.
- Wear Appropriate &
Comfortable Clothing
- Tailor the Lift: you need to ensure
your exercises are specific to the body areas you want to improve.
- Don’t hold your breath
when lifting weights: Breath out when lifting weight.
- Use a full range of
motion:
this works the muscle fully and reduces the risk of joint injury.
- Control the Weights: perform the activity
slowly and with control. Moving other body parts only increases the risk
of injury.
- Rest: in between sets of 1-2
minutes.
- Modify Program: ensure you see a
sports physiotherapist to vary your program in terms of intensity, volume
and variety, to provide continued improvement in fitness and strength.
- Stop Program: if you injure yourself
or feel pain. Seek an assessment by your sports physiotherapist.
Musculoskeletal
Screenings - Are they Useful?
We are once again just entering the commencement of
the competitive Winter sports seasons, where athletes at all skill levels are
trying to regain their aerobic fitness that was somehow lost over the summer
break as fast as possible. Our kids will now resume playing multiple sports at
both their schools and local sporting clubs.
During the Pre-Season Campaign, if not prior to, it
is important to develop good aerobic fitness, muscle strength, control and
balance, and to maintain good muscle length. If any of these factors are not
adequate for any joint or muscle, the risk of injury is increased.
Musculoskeletal screenings of athletes were
introduced at the Australian Institute of Sport in the mid-1990’s. The aim of
these screenings was to prevent injury, maximise performance and identify
injury trends within individual sports. Since this time, musculoskeletal
screening protocols have been adapted for each sport by sports physiotherapists
associated with each of the State Institute Program’s throughout Australia.
Performing musculoskeletal screenings prior to
commencing a sporting season remains our best method of assessing athletes for identification
of potential risks of injury. Once identified, an individualised program is
then designed to address the problem areas for the athlete to include into
their normal training routines. This then ensures these risks are no longer a
factor when the training / games / season become more intense, which reduces
the risk of injury occurring.
The tests carried out during a screening varies with
each sport depending on the physical demands and requirements of the sport.
They need to provide as much useful information about that individual athlete,
which can then be compared to the known injury trends and risk factors for that
sport. The tests will look at general joint range of motions and muscle
lengths, as well as a number of sport-specific tests. For example, netball is
predominantly a lower limb sport, and hence the majority of a netball
musculoskeletal screening concentrates on a biomechanical assessment of the
lower limb (leg and foot) as that is the region that is most often injured. Hence,
a hop lunge test replicates the sudden stopping required when playing netball.
In contrast to this, a swimming screening concentrates on the upper body (trunk
and upper limbs). A common swimming screening test is getting athletes to lift
both their arms up together while they are on their stomach, which assesses
their thoracic (upper trunk) flexibility.
A musculoskeletal screening can provide invaluable
information to an athlete, whether recreational or elite, for them to independently
manage potential injury risks before they occur. This will then
minimise the time they may spend on the sidelines watching their teamates play!
