| Summary: | Moderate physical activity and adequate nutritional intake arebelieved can enhance immune function of an individual. To date, little is known about
combination effects of exercise and oat bran consumption on immune functions in 40 to 50
years old women. Therefore, the present study was carried out. This study
was carried out to examine the beneficial effects of combined brisk walking exercise and
oat bran consumption on immune functions in 40 to 50 years old women. Thirty three 40 to 50 years old women were recruited and assigned into three groups, with
eleven participants per group (n= 1 1): sedentary without oat bran consumption control (C),
oat bran consumption alone (Ob) and combined oat bran consumption and brisk walking
exercise (ObEx) groups. The brisk walking exercise was performed by the participants
three times per week for six weeks. Oat bran powder was consumed by the participants
with two sachets per day (18g of oat bran powder containing 3.6 grams of P-glucan)
diluted with plain water, 7 days per week for 6 weeks in Ob and ObEx groups. Participants
in ObEx consumed oat bran drink one hour before performing the exercise. Immediately
before and after six weeks of the experimental period, participants’ anthropometric
parameters were measured. Blood samples were taken before and after experimental period
in order to measure total white blood cells, neutrophils, basophils, eosinophils, monocytes, total lymphocytes, total T lymphocytes (CD3+), T helper cells (CD4~), T cytotoxic cells
(CD8+) and natural killer cells (CD16+) for determining the level of immune functions Participants’ body weight decreased significantly (p<0.05) at post test in Ob
and ObEx group. There were significant (p<0.05) increases in eosinophil and neutrophil
counts in post test compared to pre test in Ob group. There were also significant (p<0.05)
decreases in values of T cytotoxic (CDS^ and natural killer cells (CD16+) in post test
compared to pre test in ObEx groups. For white blood cells, monocytes, basophils, total
lymphocytes, total T lymphocytes (CD3+) and T helper cells (CD4+), no significant changes were observed in post test compared to pre test among all groups. Six weeks of oat bran consumption alone elicited the beneficial effect on
immune functions. Thus, consumption of oat bran alone may have the potential to be
recommended for increasing immune functions in 40 to 50 years old women. Nevertheless,
future study with different exercise intensities and longer duration are proposed to be
carried out to investigate the effects of combined oat bran consumption and brisk walking
exercise on immune functions in this population. |
