The development and publication of the “Australian Evidence-Based Physical Activity Recommendations for Adults (18-64 years)” by the Australian Government, The Department of Health (August 2012) promote the participation in “muscle strengthening activities” to:
• Manage blood pressure, blood sugar and blood cholesterol levels.
• Prevent and control heart disease and type 2 diabetes.
• Improve posture, mobility and balance.
• Reduce the risk of falls and injury.
• Maintain your ability to do everyday tasks.
Evidence? Who needs evidence………
However, let me inform you that there are components of these guidelines that have virtually no supporting scientific evidence. The advice that “I could do tasks around the house that involve lifting, carrying or digging” whilst facilitating energy expenditure and contributing to an active lifestyle are not well defined and are somewhat nebulous. For example, lifting a chair up, carrying a full bag of rubbish to the outside bin or doing some gardening will do very little to nothing to improve your muscle strength or power. Many of these are normal everyday activities that pose no significant challenge to our musculoskeletal system and hence will be unlikely to bring about full realisation of the benefits mentioned above. Perhaps you could contend that heavy digging that produces fatigue and requires constant breaks could be classified as “strength-like” training, but how many people (unless doing as a job) are out in the backyard doing regular heavy digging every week.
Is this enough?
If you really want to improve your muscle strength and power, which has been shown to have so many benefits for older adults, and that I have outlined elsewhere (see here), you need to perform challenging resistive-type physical activities or exercise that involve “high effort”. You can utilise a number of different things to do this (e.g. traditional apparatus like barbells/dumbbells, kettlebells, machine weights or plain old bodyweight-based exercises or resistance bands or anything around the house that is challenging to to lift and move around…in fact pretty much anything if you know how) – but most importantly when you use any of these things the muscle work needs to be hard to very hard for you and/or high to very high in effort. If you meet such requisites you can be confident that what you are doing is resistance or strength training and will consequently help achieve the benefits mentioned previously.

Published in the American Journal of Clinical Nutrition, researchers Dr Thomas Longland and co. showed that during marked energy deficit a diet higher in protein was more effective in promoting increases in lean body mass (muscle) and losses of fat mass when combined with a high volume of resistance training (weights) and anaerobic exercise (sprints).
Protein requirements are increased during intense exercise training
When attempting to decrease body fat through intense exercise and an energy deficit diet, ensure you consume high protein foods (i.e eggs, fish, meat, WPC etc) regularly across the day to maintain a steady supply of amino acids to help facilitate muscle recovery and adaptation. This study provides further confirmation of the importance of adequate protein to support muscle protein synthesis.
This is particularly important in older adults with the latest review of the evidence (discussed here) showing that maximising skeletal muscle protein synthesis rates during recovery from resistance training exercise in younger adults being different to older adults. The ingestion of ∼20 g of protein or ∼0.25 g protein/kilogram bodyweight appears to be sufficient. Older adults, on the other hand, demonstrate a blunted post-prandial muscle protein synthetic response. Older adults as opposed to younger adults therefore require higher amounts of protein during recovery from resistance training exercise to optimally stimulate muscle protein synthesis. Intakes even up to ∼40 g appear necessary. Currently, no consensus exists regarding the amount of protein required to maximally stimulate skeletal muscle protein synthesis rates during recovery from resistance training exercise in older adults.
Further comments:
Interestingly, one of the key takeouts of this study is that an energy deficit diet was utilised to elicit fat mass loss. It is very important to acknowledge that the research conducted over the last 8 decades has conclusively demonstrated that weight or fat loss will only occur if this fundamental physiological requirement is met. For an extensive discussion of this research and what the metabolic-unit based weight loss studies reveal see here.
No caloric deficit = no fat loss
Therefore, don’t believe the hype. Food quality is a an absolute must and essential to good health. However, weight or fat loss will not be realised no matter how good your diet is unless an energy deficit exists. Increased total physical activity during all waking hours and an energy-deficit diet that is wholesome, natural, minimally-processed and nutrient-dense will provide a significant opportunity for weight loss to be achieved.
Lastly, there are a number of studies and anecdotal evidence that show a significant proportion of exercisers eating an ad libitum diet – possibly as high as 50% – do not achieve the weight loss expected with as much as 15% actually gaining weight. These individuals are often referred to as ‘non–responders‘. Those on the other hand that do achieve weight loss from exercise are referred to as ‘responders‘. The question is, how is this possible and are there any practical solutions? Please see herefor more on the compensatory mechanisms that some suffer from that can thwart the success of an exercise program and some of things that can be done to combat this resistance to fat loss.

Many people have wondered and I often get asked what is the symbolic meaning and intended message behind the FitGreyStrong logo?
In the picture displayed, I have deconstructed various aspects of the FGS logo and the messages behind the image that I hope to convey. Here I have tried to embody the notions of a healthy ageing body sitting atop a stack of weights where science has demonstrated repeatedly the ability of resistance training to delay the loss of muscle mass whilst simultaneously maintaining muscle strength, power and physical function. “Grey”, a signature sign of ageing is coupled together with the words Fit and Strong, both virtuous characteristics of ageing well, to bring context and meaning to the image. In deep contemplation and thought, a process of intellectualisation and careful consideration of how best to prescribe exercise, is at the forefront of FitGreyStrong.
The objective: To educate, supervise, train, support, advise, and facilitate older adults gaining some degree of control over their future health, wellbeing and quality of life.
