10 Reasons to Strength Train
During the past few years, more and more studies have shown that sensible strength training produces many health and fitness benefits. Key researchers have provided a wealth of data on the strength exercise. Consider these 10 reasons to strength train:
1. Avoid muscle loss
Adults who do not strength train lose between 2.2 kg and 3.2 kg of muscle every decade. Although endurance exercise improves our cardiovascular fitness, it does not prevent the loss of muscle tissue. Only strength exercise maintain our muscle mass and strength throughout our mid-life years.
2. Avoid metabolic rate reduction
Because muscle is very active tissue, muscle loss is accompanied by a reduction in our resting metabolism. Research indicates that an average adults 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, research shows that a standard strength training program can increase muscle mass by about 1.4 kg over an eight week period. This is the typical training response for men and women who do 25 minutes of strength exercise, three days per week.
4. Increase Metabolic Rate
Research reveals that adding 1.4 kg 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 exercise use more calories all day long, thereby reducing the likelihood of fat accumulation.
5. Reduce body fat
In a 1994 study, strength exercise produced 1.8 kg of fat loss after three months of training, even though the subjects were eating 15% more calories per day. that is, a basic strength training program results in 1.4 kg more muscle, 1.8 kg 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 increases in the bone mineral density of the upper femur after four months of strength training exercise.
7. Improve glucose metabolism
Researchers have reported a 23% increase in glucose uptake after four 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 has shown that strong low-back muscles are less likely to be injured than weaker low-back muscles. A recent study found that low-back patients had significantly less back pain after 10 weeks of specific (full range) strength exercise for the lumbar spine muscles.
9. Reduce resting blood pressure
Strength training alone has been shown to reduce resting blood pressure significantly. A 1995 study revealed that combining strength and aerobic exercise is an even more effective means of improving blood pressure reading. After two months of combined exercise, the study participants dropped their systolic blood pressure by 5mm Hg and their diastolic blood pressure by 3mm Hg.
10. Improve blood lipid levels
Although the effect of strength training on blood levels needs further research, several studies have revealed improved blood lipid profiles after seven weeks of strength exercise. It is important to note improvements in blood lipid levels are similar for endurance and strength exercise.
