Effect of Circuit Training Intervention on the Muscular Fitness Ability of 13 to 15 Years Old Female Students

Methods:

The study was conducted using a quasi-
experimental design for eight weeks. Thirty female

students were selected as subjects of this study and they
were selected using s lottery system of simple random
methods. The measure of muscular endurance and
muscular strength of the participants of the study was
recorded instantly preceding and following the 8-week of
circuit training intervention. The study was established
the mean along with standard deviation using a paired
sample T-test. Statistical Package for the Social Science
(SPSS) was used to carry out all of the statistical data
analysis. The statistical significance level was set at p <
0.05.Result:
The study was discovered that circuit training
experiences a significant change on leg explosive strength
(35.67±3.84 and 38.60±3.24 squat) of circuit group but
not (37.67±3.28 and 37.87±3.38 squat) control group. It
also improves abdominal muscle endurance (18.64 ±
2.846 and 22.93±4.873 sit ups in 1 minute) of
experimental group but not (21.11±6.249 and
21.58±5.610 sit up in 1 minute) control group. It also
improves core muscle strength and endurance
(76.20±32.00 and 79.87±34.90 second) of circuit group
but not (76.20±32.005 and 76.36±31.87 second) control
group.Conclusion:
The results of this study reveal that a circuit
training intervention was successfully improving
muscular endurance and muscular strength of female
students. This could support school teachers in specific
physical education teachers to arrange circuit training

schedule in the schools to improve schoolchildren’s
muscular endurance and muscular strength.
