Concurrent training involves the planning of the sessions where the focus is on multiple bio-motor abilities at the same time. The benefit of such methodology is to reduce the duration of a programme by typically combining resistance training (RT) and aerobic training (AT).
Current literature supports the use of concurrent training but with some implications of deteriorated performance. Some studies have shown that concurrent training can impair muscular endurance which can also affect overall performance. With support from multiple studies, it was found that there’s a strong association between maximal oxygen uptake (VO2max) and concurrent training (RT and AT). As VO2max increases, interference of performance is greater.
As established, the focus of this study was to determine the impact of concurrent training on performance. However, with little research into the effects at different intensities of concurrent training, the authors have opened a new discussion within this field. Additionally, the literature behind the repercussions of detraining following a concurrent model is lacking. Collating all of the above, the purpose of this study was now to determine the impacts of concurrent training at different AT intensities, followed by an assessment of performance after a detraining period.
There were significant improvements in performance in all groups pre and post-training; T10 (LIG: 4%; MIG: 5%; HIG: 2%), T20 (3%; 4%; 2%), CMJ (9%; 10%; 7%), 1RMest (13%; 7%; 8%), and oxygen uptake (V̇o2max; 10%; 11%; 10%). Interestingly, 1RM strength gains were significantly higher in LIG compared to the other groups.
Differences in detraining presented some interesting results. LIG demonstrated the slowest deterioration in performance by 1%.
To summarise, concurrent training of both strength and aerobic associated bio-motor abilities can improve performance at different intensities. To maximise strength gains with the minimal loss of performance, fitness professionals should adopt a lower intensity aerobic component. This could ensure lower interference of performance whilst reducing the time spent training on different modalities. This applies to the healthy population who wishes to improve explosiveness.
The exercises and focus of this study have revolved around the lower-body musculature. Transfering the findings to the upper-body may not yield similar results.
