Abstract:
The cardiorespiratory adaptation relies on the features and efficacy of the training
regimen; practitioners benefit more from a time-efficient training routine. Thus,
this study aimed to compare the effect of three different concurrent training:
Traditional Concurrent Training (TCT), Sprint Interval Training (SIT), and High
Intensity Resistance Circuit-Based Training (HRC) protocols over 08 weeks on
cardiorespiratory adaptation in young recreationally trained male athletes. Thirty
four young males were recruited (24±5.8 years, 174.9±5.9 cm height, and
73.4±7.9 kg) and randomly assigned to three groups (HRC: 13, SIT: 10, and TCT:
11). All subjects were exercised twice a week for 8 weeks. VO2 max, maximum
heart rate (MHR), Max VO2 R, Maximum time and maximum velocity at VO2
max were assessed. Standard descriptive statistics were used to characterize the
study population. A mixed analysis of variance with repeated measures and
Bonferroni post hoc tests were used to investigate the interaction effect and
significant differences. The main results show that significant interaction on
maximum velocity at VO2 max, while non-significant between group main effect
were detected on any measuered variables, but through the post hoc comparison
were observed significant differences (P < 0.05) on VO2 max following HRC vs
TCT and SIT vs TCT. Interestingly, there were significant main time effects
were detected on all variables except MHR.TCT induced significant difference
(P < 0.05) within group on maximum velocity (4.01 ∆%), VO2 max (4.75 ∆%),
Max VO2 R (4.82 ∆%), and maximum time (7.75 ∆%), whereas following SIT
encourage significant difference (P < 0.05) on maximum velocity (4.29 ∆%) and
maximum time (5.15 ∆%). Remarkably, it suggests that all three training
protocols are induced increases of VO2 max but TCT (4.75∆%) is better than
other training protocols (HRC: 1.81 ∆% and SIT: 2.58 ∆%). However, in
consideration of time factor HRC and SIT are very time efficient training
protocols than TCT protocol.
