The effect of continuous and interval muscular endurance training on some cardiorespiratory variables and trained runners’ records

Document Type : original article

Abstract


purpose: This study was designed to investigate the effect of continuous and interval muscular endurance training
on some structural and functional cardio respiratory variables and trained runners’ records. Methodology: 27 young
men voluntarily participated in this study. After the introduction session, based on the one-mile record, the subjects
were randomly assigned to three groups, namely, interval group, continuous group, and control group, with a mean
(±SD) (19.89 ± 3.40 yr , 186.04 ± 5.23 cm , 77.97 ± 8.55 kg). In order to measure the structural and functional
cardiac variables, two-dimensional and Doppler echocardiograms were used. All The Participants performed the
exercises in three sessions per week for 8 weeks. For statistical analysis, a one-way ANOVA and the Bonferroni
post hoc test were utilized. Results: The eight- week continuous and interval muscular endurance training had a
significant effect on the variables under study (p< 0.05). The results indicated that it had the greatest effect on
maximal oxygen consumption, maximum aerobic speed, anaerobic threshold velocity, and left ventricular ejection
fraction, and runners’ records in the interval group, and on the stroke volume in the continuous group. With regard
to the intra ventricular septum and maximum exhaustion, there was no statistically significant difference among
groups. Conclusion: The results indicated that for the purpose of enhancing some variables, which have been
strengthened via continuous training, interval training can also be as beneficial.
