increasing muscle cell protection and decreasing
muscle damage, membrane leakage, soreness, fatigue
and injury.
A degree of muscle soreness and fatigue are part
and parcel of any training program, but with strategic
feeding strategies we can support repair and refuelling
and hasten muscle recovery. Whilst lactic acid has
been touted as the major cause of fatigue and muscle
soreness, recent studies have shown this to be
incorrect. Muscle glycogen is always the limiting factor
for fatigue, whilst soreness is due mainly to muscle
damage.
Prolonged strenuous exercise can result in muscle
soreness caused by microtrauma to muscles and
surrounding connective tissue leading to a local
inflammatory response. There are reports that MSM
(methylsulphonylmethane) is effective against muscle
soreness because of its anti-inflammatory effects as
well as its possible sulphur contribution to connective
tissue. Measurements of exercise-induced muscle
damage and muscle enzyme leakage were reduced
with MSM supplementation.
Formulated with an understanding of the biochemical
and hormonal effects of exercise on the muscle and the
roles of each nutrient Jenquine has recently released
all-4-feet ® to provide high levels of essential amino
acids, anti-oxidants, omega 3 oil and the vitamins
and minerals required to support recovery. Feeding
150 to 500 grams of Jenquine all-4-feet ® before
and after work supplies the precise combination of
nutrients the muscle requires to transition to protein
synthesis and the bone marrow uses to increase red
cell production. This enables the muscles to recover
quicker, increases the response to training, reduces
the incidence of delayed muscle soreness and allows
the horse to tolerate increased work. Reducing the
need for multiple supplements, and when fed before
and/or after work with a small amount of lucerne, the
risk of stomach ulcers is reduced.
MUSCLE REFUELLING:
After encouraging muscle repair and lean muscle
building, a second, separate issue is muscle refuelling.
Exercise can decrease muscle fuel (called ‘glycogen’)
by 20-40% and the replenishment of glycogen is
important in determining the time needed to recover
from exercise. The period of most rapid uptake and
glycogen repletion is in the first hour after work – and
certainly within 3 hours. The enzymes that facilitate
muscle glucose uptake and glycogen synthesis remain
elevated for up to 3 hours after work.
