Benefits
of strength training

Resistance training is probably the most misunderstood form of training
in keeping fit and healthy. My goal in sharing this article is to
help you better understand the benefits of resistance training and
encourage you to make a positive change in your life.
Resistance or strength training involves using different muscle
groups to lift weights. Resistance training comes in the following
form:
 |
Lifting of
dumbbells |
 |
Raising legs with ankle weights
attached |
 |
Pulling on/against rubber exercise
tubings/bands |
 |
Even engaging in sports such as
impact-based kickboxing |
|
 |
Advantages of resistance training include and
not limited to:
 |
Increase in bone density |
 |
Cardiovascular benefits |
 |
Improve metabolic efficiency (Building/maintain muscle) |
 |
Positive gains in the frail elderly |
 |
Improved stroke-related disabilities |
 |
Fight against depression |
|
 |
Increase bone density
Firstly, weight-bearing
exercises have been strongly advocated by medical professionals
to increase bone mass in women and so prevent the onset
of osteoporosis after menopause.
|
|
 |
Recent studies have
shown that resistance training is also effective in
increasing bone density, and in fact, may be more effective
than aerobic training.
The USDA Human Nutrition Research Center at Tufts University
in Boston conducted a small study of 39 postmenopausal
women and observed the following:
|
| |
|
 |
Increase in bone mineral density of the
hip and spine among the trained women |
 |
Improvement in muscular strength and balance in the
resistance trained women. |
|
Cardiovascular benefits
Resistance training
offers the following cardiovascular benefits as well:
|
| |
|
|
Improved heart disease
risk factors |
|
Assists cardiac rehabilitation
after a heart attack |
|
Improve heart failure |
|
|
|
 |
A cardiac rehabilitation
study in Canada investigated the effects of resistance
training among men recovering from heart attack observed
the following maximum strength gains:
|
| |
|
| |
10% increase in low
intensity resistance training group |
| |
12% increase in medium intensity
resistance training group |
| |
14% increase in high intensity
resistance training group |
| |
|
30 out of the 57 involved
men, experienced heart complications during the aerobic
exercise (chest pain, abnormal rhythms, rise or drops
in blood pressure), but only one had cardiac problems
during resistance training. This provides evidence that
resistance training is not only beneficial for cardiac
rehabilitation, it is safe as well. |

Metabolic efficiency
We lose one-half pound
of muscle every year after 25 which in turn results
in a one-half percent reduction in Basal Metabolic
Rate (BMR) every year.
‘Basal Metabolic Rate’
refers to the energy used by our body at rest to maintain
normal body functions. A reduction of BMR simply means
our bodies are less able to use consumed food as energy,
this in turn gets stored as body fat.
|
|
 |
With high energy requirements,
our muscles use more than 25% of our energy (calories),
even when we are sleeping. Resistance training will
enable you to achieve an increase in lean muscle mass
throughout your body and thus increase your BMR.
As we age, our muscles and BMR will decrease
and body fat will increase, especially if we
do not incorporate a sound strength training program.
In order to decrease the body fat percentage and risk
of disease, strength training should be included to
assist in the conditioning of the (metabolism) BMR.
There are still many who do not choose to do strength
training mainly because they mistakenly think that this
type of training will make their body big and bulky.
One footnote- women maintain lower levels of the male
muscle-building hormone testosterone which makes them
unlikely to gain what is considered muscle bulk.

Positive gains in the frail elderly
The frail elderly can
also benefit significantly from resistance training.
A Pennsylvania State University study of 100 elderly
nursing home residents reported significant gains in
strength, functional status and spontaneous activity
levels in the trained patients after the patients were
assigned either a high intensity resistance training
program or a control group.
The USDA Human Nutrition Research Center on Aging at
Tufts University in Boston conducted a smaller but similar
study with ten frail 90+-yearold nursing home residents
with 9 of them reporting the following gains:
|
| |
|
 |
174% average gain in
strength |
 |
9% increase in size of the thigh
muscle |
 |
48% increase in walking speed |
| |
|
Based on these results,
researchers suggested that even the very oldest among
us may benefit significantly from resistance training. |
|
Improve stroke-related disabilities
|
Resistance training have been prescribed
to reduce the resulting disabilities of survivors of mild
to moderate stroke as investigated in a Boston University
study involving 42 stroke survivors over the age of 50. After
putting them through a 12-week, high-intensity, progressive
training program for the lower body, these patients had improved
extremity strength and reduced functional limitations. |
Fight against depression
Resistance training
not only gives rise to physical benefits, but also strengthens
you psychologically and emotionally. 14 studies involving
exercise therapy used to treat people with clinical
depression found that sufferers were significantly less
depressed after 5 weeks of performing weight training
3 times a week for 20 to 60 minutes.
|
|
|
 |
Another Harvard University study involving 60 women
were asked to do an initial assessment of how they
felt about their bodies in the following groups:
|
| |
|
 |
Walking group |
 |
Resistance training group |
| |
|
At the end of the 4-week
study, the resistance training group displayed a level
of self-esteem twice that of the walking group. The
doctors who conducted the study explained that the fast
results experienced with resistance training was the
reason for the dramatic difference. A woman starting
with 3 pounds could be lifting 5 or 8 pounds in 3 to
4 weeks. This type of achievements empowers women!
Having seen the positive benefits which resistance
training can bring to an individual, we should not
hesitate to incorporate a resistance training program
in our lives.
Start resistance training today and experience the
health benefits and you will gain an extraordinary
level of confidence to take on the world. With soaring
energy levels, your concentration will improve tremendously
and most importantly – Feel good about yourself!
Here's to your health!
