advice on low lung capacity and running/cycling. I was diagnosed with 66% lung
capacity, I am 36 years old, and though I do run and cycle, I battle the whole
way with my breathing. Is there anything I can do to improve my breathing or
running as I am getting very despondent? –
there is nothing you can do to get back to 100% of your lung capacity, but you
can better utilise the 66% you do have available. You are born with a
particular maximum lung capacity which is called VO2max – maximum rate of
oxygen flow, also known as aerobic capacity. In your case, you only have 66% of
your VO2max, hence the importance of training smart.
Testing is considered to be the most important determinant of success in
endurance activities. Training at the right intensity is important to help you
reach your goal. During training, your body uses glucose as energy, and the
by-product of this glucose breakdown is lactate. To get rid of the lactate in
your blood, you need enough oxygen to break down lactate and re-use it as
energy. When you don’t have enough oxygen and produce too much carbon dioxide,
lactate can’t be broken down and it accumulates in the blood, and eventually you
and lactate tests, we can identify the most appropriate training intensity and
type of training for you specifically, to build your fitness level at your own
pace. However, it is easier just to start running slower and concentrate on deep
belly breathing, which may aid in increasing your lung capacity and efficiency.
It expands the diaphragm to its max during inhalation and uses your abdominal
muscles to squeeze air out during exhalation, resulting in more oxygen reaching
the muscles per breath.
I am 37 years old and a casual
runner. I have done about six 10km and 15km events. I experienced a terrible
pain on my right knee during my last 15km race and I could hardly walk or climb
up the stairs afterwards. I rubbed my knee and after a week the pain was gone,
but it started again when I attempted exercising again. What is the cause of
this and what can I do for the pain to go away permanently? – Thenji Masuku
It sounds like you have patellofemoral knee pain, also known as runner’s
knee. The pain is localised around inner and outer border of the kneecap, is
felt while running, and generally gets progressively worse and is aggravated by
longer distances. Sitting for long periods, squatting and walking up and down
stairs can also cause discomfort. This pain can result from several causes:
Excessive pronation of your foot. Check for
abnormal wear on your shoes.
Weak hip muscles which result in inward rotation
of the thigh, resulting in increased pressure under the kneecap.
Training errors which include building mileage
too quickly, or excessive speed or downhill running.
Treatment should include one or several of the following:
Anti-pronation shoes or orthotics may be
required to correct excessive pronation.
Strengthening of the thigh muscles (quadriceps)
and hip muscles to help decrease the load and pressure on the knee.
Taping can help correct altered tracking of the
kneecap and temporarily decrease the pain.
