Concurrent training is doing cardiovascular endurance and resistance training within an equivalent session or closely together within an equivalent day. Way back within the exercise science world, concurrent training was promoted as how to save lots of time while reaching multiple training goals. More recently, however, it’s clear that the mechanisms of cardiovascular endurance training and resistance training compete with each other at the molecular level. Under certain situations, they will cancel one another out. This essentially renders significant muscle strength and power outcomes nonexistent. The first landmark study on concurrent training outcomes showed that muscle strength actually decreased during the last 2 weeks of a concurrent training study period during which the themes did both cardiovascular endurance and resistance training. These results were significant because they showed that cardiovascular training ceased upper-end strength improvements while leaving cardiovascular endurance, as measured by VO2max, unaffected. Since 1980, the message has been that cardiovascular endurance training interferes with muscle strength performance which the body tends to favor cardiovascular endurance outcomes over muscle strength outcomes.
Concurrent training causes muscle confusion at the molecular level. Consider these muscles get confused a bit like you are doing. If you walk into a spin center ready for a spin class only to seek out Pilate’s equipment on the ground, you get confused. Muscles are an equivalent way. When two competing sorts of exercise, like cardiovascular endurance training and resistance training, are performed during an equivalent workout session, the involved muscles become confused. Ashore goes on to elucidate that muscle confusion occurs at a molecular level; the molecular mechanisms related to cardiovascular endurance and muscle strength and power are different. When the 2 modes of coaching occur too draw in time, muscles simply don’t know what to try to. Within the end, the molecular mechanisms related to muscle strength and power performance are sacrificed at the expense of cardiovascular endurance goals, and results are diminished.
Additional evidence suggests concurrent cardiovascular endurance training interferes with increases in muscle size and thus interferes with strength development. Researchers found that combining cardiovascular endurance and resistance training negatively affected fiber cross-sectional areas. However, during this particular study, the authors found that concurrent training compromised strength development only both modes of exercise engaged an equivalent muscle group, suggesting an area effect instead of a systemic one. Subsequent studies show something different about local versus systematic effects of concurrent training. One study examined the consequences of lower-body sprint interval training on upper-body hypertrophy and strength. The results showed that sprint interval training combined with resistance training adversely affected upperbody hypertrophy and strength. This finding is critical because it's counter to earlier research suggesting an area effect of concurrent training.
The study showed that the consequences of concurrent aerobic endurance and resistance training aren't muscle-use specific. Lowerbody sprint interval training adversely affected upper-body strength performance; therefore, the consequences of endurance training affect nonworking muscles. This is often significant in concurrent programming during which most modes of cardiovascular endurance training use the lower body. It appears supported by this study that the upper-body muscles aren't spared the negative consequences of concurrent training and interference, even when not used. The results suggest that the mechanisms liable for interference can't be avoided by working for different muscle groups during cardiovascular endurance and resistance training. However, where strength decrements were found during weeks 9 and 10 of the concurrent training programmer, measures of cardiovascular endurance work showed no negative effects of fatigue on endurance from concurrent training, again suggesting that the consequences of concurrent training preferentially affect strength development.
