Can walking be as effective a form of exercise as running? - Tony Paladin (Paladin Biokineticists)

Whenever we are going to relate things to one and other, it is always best to adopt the old adage of “comparing apples with apples”. Comparing apples with say bananas makes for good conversation; but it doesn’t actually address the cold, hard facts.

The debate about walking vs. running and the respective health benefits of each has swung like a pendulum for decades between Doctors, Surgeons, Biokineticists, Physiotherapists, Athletics coaches and Personal Trainers.

Before we can critically comment on whether walking can be as effective as running we would need to define what exactly: “form of exercise” means. If we loosely reference the World Health Organisation’s definition of “exercise”, we can break the components into functional / balance, flexibility, strength and cardiovascular.

If we use these components as indicators, we can critically assess whether walking is as “effective” as running.

From a functional / balance perspective, the slower the movement the greater the stimulus. Generally walking is a good choice for people who need to improve basic function, increase activities of daily living and enhance balance. The function / balance components can be respectively varied in difficulty by offering assistance or creating instability. Verdict = when it comes to training basic function and balance, walking wins.

Flexibility. Unfortunately on this front, neither walking nor running has much to offer in terms of increasing muscle and joint range of motion. If I had a loaded gun to my head and was asked to make a call, I would have to say that across the walking / running echelon, sprinting would probably elicit the greatest effect on flexibility due to the ballistic and elastic components of the activity. Verdict = Do Yoga or full range of motion exercises such as squats in conjunction to your walking and running program.

When we introduce strength into the walk / run debate, we end up with a chicken and egg situation. Does one need to be strong to walk and run or does walking and running make you strong? Lets make walking the chicken and running the egg. Walking is the most elementary form of movement; it is literally one step harder than sitting. From the perspective of rudimentary movement, it is logical that one should start with the basics prior to advancing the activity. The “basics” in this case, is walking and when advanced, is running. Strength however, nestles itself quite firmly in between the two activities: you need to be strong to run. Do we go with the chicken or the egg? Since neither walking nor running really develops strength, it is advisable to include other movements in your program, which do. Verdict = Walking should be progressed to incline walking which should be progressed to fast incline walking which should be progressed to running. Strength exercises should be included across the entire stratum.

Then we have the cardiovascular component. In short, the faster your heart beats, the more “cardiovascular” the modality of exercise is. One could argue that it is a no brainer that running elevates your heart rate more than walking does, but does it really? Running sloppily on a flat surface at a slow pace versus brisk walking with a backpack up a hill is like comparing apples with bananas. If we compare apples with apples; as a general rule running elicits more of a cardiovascular response on the body due to the speed of the activity. The body needs to work harder to run than to walk. If we are going to get walking to obtain the same level of work, we need to make it more difficult. This can be done with speed, resistance, hills and direction. Verdict = from a cardiovascular perspective, walking with purpose has the potential to topple lackadaisical running.

So… Shall I walk or shall I run? For the non-injured and mostly healthy community, running has the ability to elicit more of an exercise response than walking and should probably be the mode of choice. For individuals with joint problems or who are simply not fit enough to run, walking is a heck of a lot better than bum sitting in terms of exercise response. Even when walking is too easy and running is too hard, walk-running is also an alternative to get the heart rate up but still allow for bouts of rest. The bottom line is your ability: exercise is meant to be both challenging and enjoyable.


With regards to general health benefits, increased fitness, toning and weightloss; the American College of Sports Medicine (ACSM) recommends that adults get at least 150 minutes of moderate-intensity cardiovascular exercise per week; strength train each muscle group two to three days a week; do flexibility exercise two to three days per week; and finally, do functional exercise two or three days per week. Whether you choose to walk or run is your choice, just make sure your heart is beating while you are doing it!

What is Hypertension and how does a Biokineticist play a role in addressing it? - Anca Wessels (Paladin Biokineticists)

So you’ve heard of the term “high blood pressure”, but what does it really mean?

When your heart beats, it pumps blood out. The pressure it produces is called your systolic measurement (top reading) and should average at around 120.

When your heart is resting in between beats, it gets filled up with new blood. The amount of pressure needed to do this is called your diastolic measurement (bottom reading) and should average at 80.

If your blood pressure measurement is higher than 120/80 (eg. 150/100), you could be suffering from high blood pressure (hypertension). This means that the amount of pressure needed to pump and fill your heart is higher than normal and could lead to your heart being over worked. If left undiagnosed and untreated for an extended period of time, you could suffer from a heart attack or heart failure.

If you’ve been diagnosed with hypertension, one of the treatments that can assist in decreasing your reading is regular specific exercises. This is where Biokineticists come in.

Exercise for hypertension is specifically designed to train your heart how to deal with access pressure. These pressures can include anything from being overweight, to additional work stress, to being very unfit, to financial problems, etc.  By increasing your heart’s capability to adapt to different situations, you will lower your blood pressure and increase your quality of life.

Parkinsons and the effects of Exercise - Michael Irvine (Paladin Biokineticists)

Parkinsons is a degenerative disease where the brain cells that affect the control of movement slowly dies, resulting in disturbances in the messages being relayed from the brain to muscles. This inhibits or negatively affects movement. This mechanism can be explained physiologically by a chemical produced in the brain cells called dopamine, which is used by the nerve cells to help control movement. When an individual has Parkinson’s, these brain cells die making it hard to control the muscles involved in movement. Another factor involved in the neurological damage is the occurrence of protein misfolding and formation of distinct aggregates. This results in a putative pathological protein load on the nervous system. Symptoms of parkinson’s occurs when there is more than an 80% loss of dopaminergic cells.

Symptom
Classic symptoms of Parkinson’s include:

1.      Rigidity and trembling of head
2.      Forward tilt of trunk
3.      Reduced arm swinging
4.      Rigidity and trembling of extremities
5.      Shuffling gait with short steps

Parkinsons is an idiopathic condition, therefore it is not clearly known what causes the cells to waste away. Parkinsons is a highly researched disease to help us possibly prevent and treat it better.

Speculated causes:
  • ·         genetics
  • ·         mitochondrial dysfunction and antioxidants
  • ·         occupational exposures (pesticides, herbicides, and heavy metals)
  • ·         smoking, coffee, and alcohol.


Exercise and Parkinsons:
Research over the last couple of years has uncovered a large amount of evidence that exercise is an effective form of treatment for Parkinson’s disease and could delay the steady decline of the disease. Studies using animals found that exercise has protective benefits towards the onset of Parkinsons symptoms. This appears to be due to the release of neurotrophic factors, greater cerebral oxygenation which both promote new cell growth and survival.

Exercise helps stimulate dopamine synthesis in the remaining dopaminergic cells, thus reducing symptoms. Research suggests exercise enhances neuroplasticity in Parkinson’s patients via 5 key principles:
1.      Intense exercise maximizes synaptic plasticity
2.      Complex exercise promote greater structural adaptation
3.      Rewarding activities increase dopamine levels which promotes learning/relearning
4.      “Use it or Lose It” phenomenon (dopaminergic neurones are highly responsive to exercise and inactivity)
5.      Exercise if done early slows down the progression of the disease.
Taking into account these 5 key principles of exercise and Parkinson’s disease, exercise has shown to provide many benefits to Parkinson’s patients such as:

·         Increased health related quality of life
·         Decrease in disease severity
·         Increased muscle strength
·         Increased aerobic capacity
·         Increased physical functioning
·         Increased balance
·         Improvement in walking speed/ability
