Fortunately, the times when it was thought that, by holding a dumbbell, women would develop a bodybuilder's muscles passed into history.
At this point in the film, no one doubts that
working on muscle strength is essential
for women's health.
In each of the stages of life, from puberty to menopause, the physiology of women changes, producing
hormonal fluctuations
that affect
metabolism
,
muscles
and
tissues
, among others.
If, during childhood
, strength exercises provide benefits for bone health
, both for girls and boys, when they reach adulthood they are one of the most effective tools for preventing
osteoporosis, injuries, cardiovascular diseases and sarcopenia
(loss of strength and muscle mass in old age).
These are, according to Laura Esquius, director of the UOC university master's degree in Nutrition in Physical Activity and Sport, and Cristina Rotllan, collaborating professor of this master's degree, the main
physical, physiological and mental benefits
of strength training in women:
1. Reduces the risk of injury.
Strength exercises help
strengthen tendons and connective tissue
.
Therefore, they provide more stability to the joints.
This helps prevent injuries, which is especially important in women with a predisposition to knee or back injuries and in older women.
"Having strong muscles improves mobility and the ability to react to any unforeseen event, and therefore helps
prevent falls and fractures
," says Esquius, an expert in physiology and sports nutrition.
2. Contributes to fat loss.
Strength exercises increase muscle mass.
Muscles are a more metabolically active tissue than adipose tissue
, that is, they require more energy than fat.
According to Esquius, if we have more muscle mass, the caloric expenditure will be higher.
"When training is particularly intense, oxygen consumption increases, even hours after training. This causes caloric expenditure to increase to achieve more oxygenation," says the UOC expert.
3. Helps prevent osteoporosis.
In Spain, it is estimated that 22.6% of women aged 50 or over have osteoporosis.
This disorder weakens the bones and often leads to fractures of the hip and spine, thereby affecting the sufferer's mobility and independence.
For both Esquius and Rotllan, increasing muscle strength is important, especially in
postmenopausal women
, because it improves bone density and helps prevent osteoporosis.
4. Improves mental health.
Exercises like running are not the only ones that help improve symptoms of depression and anxiety.
Endorphins are also released with strength exercises, which contributes to mental well-being.
A study published in 2014 in the journal
Frontiers in Psychology
shows that the use of low or moderate weights has beneficial effects on anxiety.
In addition, as Esquius explains, it also has benefits for memory and cognitive function.
5. Reduces the risk of cardiovascular disease and diabetes.
Rotllan, an expert in Physiotherapy and physiology, explains that working on muscular resistance is an essential tool to reduce the risk of suffering from cardiovascular diseases and metabolic syndromes such as diabetes.
A study published in the journal
BioMed Research International
shows that training your muscles also improves your ability to absorb and use glucose, or blood sugar.
The expert points out that, in the case of pregnant women, the fact of combining strength exercises with aerobic exercises is associated with multiple benefits, such as the
reduction of the risk of suffering from gestational diabetes mellitus
, the maintenance of physical condition and the Reduced chances of cesarean delivery.
6. Fights effects of aging such as sarcopenia.
Sarcopenia is a syndrome characterized by a gradual and generalized loss of strength and skeletal muscle mass among older people, which can lead to physical disability or decreased quality of life.
Rotllan assures that strength training helps combat this disease, as other studies indicate.
7. Reduces the symptoms of polycystic ovary syndrome.
Polycystic ovary syndrome is a common hormonal disorder among women of reproductive age.
Women with this syndrome may have
infrequent or prolonged menstrual periods
, or excessive levels of male hormones (androgens).
One of the causes of this syndrome is an
excess of insulin
.
"Doing muscular resistance exercises is a good strategy to reduce the symptoms of this syndrome, since they improve body composition and reduce insulin resistance," says Rotllan.
BETWEEN TWO AND FOUR WEEKLY SESSIONS
Although Esquius recommends doing strength routines between
two and four times a week,
on alternate days, it is best to have the advice of a qualified professional who will design
a tailored training plan for us, based
on our physical condition and goals. .
"It is
important to warm up and stretch before training
. This favors the increase in body temperature and the activation of muscles and neuromuscular connections, so that the possibility of injury is reduced," explains the expert.
"
You can train strength without using machines or lifting heavy weights
. We can do several repetitions with
medium or light
resistance
(elastic bands, weights, etc.)
, because the most important thing is to execute the movements with the correct technique," she adds.
The great secret of success lies in
choosing the exercises that we like the most
and that best
suit our abilities so as not to fall into boredom, frustration and abandonment
.
In this way, you get extra motivation to continue training and, if you do the right exercises, avoid injuries.
strength plus aerobic
According to the Spanish Nutrition Foundation (FEN), overweight and obesity are defined as an
abnormal or excessive accumulation of fat
that can be harmful to health, that is, when the percentage of fat mass (FM) exceeds 25 % in men and 33% in women.
Obesity is associated with low muscle quality, that is, a decreased ability to produce force per unit of muscle mass.
In this sense, some studies have observed that being a woman is a predisposing factor for poorer muscle quality.
Traditionally, the practice of aerobic physical exercise has been recommended to combat obesity and overweight.
However, recent studies have shown that interventions that include the
combination of moderate aerobic exercise with muscular strength training provide more benefits
than other programs that only consider cardiovascular exercise.
"These exercise programs
decrease abdominal fat and improve lean mass and cardiorespiratory
fitness ," Rotllan concludes.
DIET AND HYDRATION
For the UOC experts, when working on physical strength, the most important thing is to follow a
balanced diet and good hydration
.
The necessary macronutrients that must be ingested depend on the main objective of the training, that is, if we want to
gain muscle mass
or if we want to
lose body fat
.
According to Rotllan, recent studies have found that
protein intake after
strength training leads to myofibrillar protein synthesis, that is, it
facilitates the ability to build muscle
.
This growth can be greater than with a diet rich in carbohydrates.
For his part, Esquius explains that women oxidize less protein than men because their anabolic response to
protein consumption after exercising
is lower.
Therefore, they
need higher intakes
to achieve the same effect.
The expert recommends distributing the
quality protein intake throughout the day and after workouts.
Some authors have indicated that an excessively high-protein diet could be contraindicated in women, due to the risk of increasing calcium losses.
However, other studies have failed to prove this relationship, arguing that
high-protein foods are also high in calcium and phosphorus
.
