10 Reasons to Strength Train: Consider these 10 reasons to strength train:
1. Avoid Muscle Loss
Adults who do not strength
train, lose between 2.2kg and 3.2kg of muscle every decade. Although endurance exercise improves our cardiovascular
fitness it does not prevent the loss of muscle tissue. Only strength exercise maintains our muscle mass and strength
through-out our mid-life years.
2. Avoid Metabolic Rate
Reduction
Because muscle is very active tissue, muscle loss is accompanied by a reduction in resting metabolism. Research
indicates that an average adult experiences a 2% to 5% reduction in metabolic rate every decade of life. Because
regular strength exercise prevents muscle loss, it also prevents the accompanying decrease in resting metabolic rate.
3. Increase Muscle Mass
Because most adults do not perform strength exercise they need to first replace the muscle tissue that has been lost
through inactivity. Fortunately; researcher shows that a standard strength training program can increase
muscle mass by about 1.4kg over an eight week training period. This is the typical training response for
men and women who do 25 minutes of strength exercise one day each week.
4. Increase Metabolic Rate
Research reveals that adding 1.4kg of muscle increases our resting metabolism by 7% and our daily calorie requirements
by 15%. At rest a kilogram of muscle requires 77 calories per day for tissue maintenance and during exercise
muscle energy utilisation increases dramatically. Adults who replace muscle, through sensible strength
training, use more calories all day long thereby reducing the likelihood of fat accumulation.
5. Reduce Body Fat
In a 1994 study,
strength exercise produced 1.8kg of fat loss after three months of training, even though the subjects were eating 15% more
calories each day. That is; a basic strength training program resulted in 1.4kg more muscle, 1.8kg less fat and 370 more calories per day food intake.
6. Increase Bone Mineral Density
The effects of progressive
resistance exercise are similar for muscle tissue and bone tissue. The
same training stimulus that increases muscle strength also increases bone density and mineral content. A 1993 study demonstrated significant increase in the bone mineral density
of the upper femur after four months of strength exercise.
7. Improve Glucose Metabolism
Researches have reported a 23% increase in glucose uptake after
4 months of strength training. Because poor glucose metabolism is associated
with adult onset diabetes, improved glucose metabolism is an important benefit of regular strength exercise.
8. Reduce Low back Pain
Years of research on strength training and back
pain, conducted at the University of Florida Medical School, have shown that strong low-back
muscles are less likely to be injured than weaker back muscles. A recent study found that low-back patients
had significantly less back pain after 10 week of specific (full range) strength exercise for the lumbar spine muscles.
9. Reducing Resting Blood Pressure
Strength
training alone has been shown to reduce resting blood pressure significantly.
A 1995 study revealed that combing strength and aerobic training is even more effective means of improving blood pressure readings. After
two months of combined exercises,
the study participants dropped their systolic blood pressure by 5 mm Hg and their diastolic blood pressure by 3mm Hg.
10. Improve Blood Lipid Levels
Although the effect of strength training on blood lipid levels needs further research, several studies
have revealed improved blood lipid profiles after several weeks of strength training. It is important to
note that improvements in blood lipid levels are similar for both endurance and strength exercise.
