A
key factor in physical and mental health, physical activity has become central
to medical recommendations. During physical effort, the muscles draw mainly on
their own reserves. The brain, for its part, relies on the reserves in the
liver. The day before a sporting event, eating a meal rich in carbohydrates, in
the form of pasta for example, is therefore an excellent strategy for
recharging glycogen stocks in both the liver and the muscles themselves. As for
D-day, the ideal is to opt for a low-fat diet and avoid eating a meal in the
hour before exercise.
The major challenge during a sporting activity is to ensure an adequate supply of fuel for the muscles in action, but also for the rest of the body, particularly the brain, which has very little tolerance to a lack of supply. During exercise, the muscles and brain have an imperative and permanent need for glucose. While glycogen reserves in the muscles and liver and, if necessary, fats, provide this glucose supply via chain reactions, a direct dose of glucose or fructose is ideal for an immediate « boost ». Opt for a piece of banana, for example.
Is
feeling thirsty a sign that the body is already dehydrated?
Thirst
is not a sign that your body is already too dehydrated, as it can encourage you
to drink too much. But the greatest risk for a sportsperson is not dehydration,
but overhydration. The body needs time to eliminate excess fluids. During
intense physical effort, this internal regulation slows down. Excess water can
then trigger a cascade of dangerous, even dramatic, physiological reactions. As
it spreads through the bloodstream, water dilutes the minerals it contains,
particularly sodium. The cells will also become waterlogged.The risk is then
the appearance of oedemas (cerebral oedemas in particular), with a potentially
fatal outcome.To avoid this danger, you simply need to listen to your thirst,
without forcing yourself to drink.
Is
vitamin C a good remedy for aches and pains?
Muscle
soreness is a sign of micro-damage to the muscles.Faced with an unusual
challenge, certain muscle fibres can be injured, causing inflammation and
characteristic pain.What can you do about it?By doing nothing.The reason is
that this micro-damage is part of the process of strengthening the muscle,
which becomes weakened and then naturally stronger.Taking vitamin C or other
antioxidants cancels out this effect.Muscle soreness generally fades as
training progresses.
Are
cramps during exercise a sign of magnesium deficiency?
Most
often, cramps are a reflection of a lack of training. A neuron's length away,
they originate in one of the "control centres" for muscular activity,
in the spinal cord. Although magnesium is sometimes put forward as a solution,
its effectiveness has not been unanimously proven. Training and a healthy
lifestyle are in themselves the best assets for tackling physical effort.
Is
it dangerous to increase protein consumption in order to build muscle? Combining
muscle-building exercises with a diet enriched with meat, eggs, fish and
possibly protein concoctions can be a good idea if you're particularly keen to
build muscle mass.To what extent? The important thing is to maintain a
balanced diet, not to overdo it and to have good kidney function.Too much
protein can be harmful for people with kidney problems and can lead to gout, an
inflammatory and painful joint disease.Beware, it is not uncommon for protein
products advertised for bodybuilding to contain doping substances.You need to
be vigilant, as the labels often do not mention their presence.
