Abstract
The purpose of this study was to assess the effect of resistance training on the flexibility of male taekwondo
athletes of the Nigerian Army. To achieve the purpose of the study a research question and null hypothesis
were formulated. A repeated measures experimental research design was used for the study. A multistage
sampling technique of purposive, stratified and simple random sampling was used to select 20 male
taekwondo athletes, between the ages of 18 to 24 and have competed in the national championship as
sample size for the study. The training intensity was maintained between 70% to 90% of one repetition
maximum (1RM) on the selected biomotor ability variable of fitness. The training programme had three
sessions of moderate to high intensity resistance training per week for a duration of 12 weeks. includes
Resistance machine, Holtain Stadiometer, whistle (fox-40) model, electronic stop watch and a calibrated
and adjustable sit and reach box for measuring the flexibility of participants was used as instruments for
the study. participants trained at 70% of 1RM from baseline to 4th week, at 80% of 1RM from 4th week to
8th week and at 90% of 1RM from 8th week to 12th week. The selected biomotor ability variable was
assessed at baseline, at the end of 4th, 8th, and 12th weeks of training period. The variable measured was
flexibility. Descriptive statistics of mean, standard deviation and standard error was used to answer the
research question, while repeated measures analysis of variance was used to test the null hypothesis
formulated at 0.05 level of significant. Findings of the study revealed significant effect of resistance
training on flexibility (p = < 0.001) of male taekwondo athletes of the Nigerian Army; therefore, the null
hypothesis was rejected. Bonferroni Post hoc Test further revealed that the significant effect of the
resistance training on the selected variables manifested at the end of 4th, 8th, and 12th weeks of training. On
the basis of these findings it was concluded that resistance training significantly improved the flexibility
of male taekwondo athletes of the Nigerian Army. On the basis of these conclusions, it is recommended
that the Nigerian Army taekwondo coaches and athletes should ensure that resistance training between 70
90% of 1 RM and periodic biomotor abilities evaluation should be integrated into their comprehensive
fitness training regimen in order to enhance Nigerian Army male taekwondo athletes’ flexibility for
performance proficiency in training and competitions.
