The purpose of this study was to investigate the effect of concurrent resistance and endurance cycle training on physiologic and performance parameters of cyclists. Before and after a 6-week training intervention period, 14 well-trained male cyclists completed a maximal graded exercise test, a...

In conclusion, although concurrent resistance and endurance training in well-trained cyclists enhanced 1RM strength, it did not improve overall cycle time trial performance and in fact was shown to reduce 1-km final cycle sprint performance compared with a CON group performing their normal cycle training. <- qui mi sento di criticare il protocollo di ricerca. Atleti che hanno svolto 3 volte a settimana allenamento di forza, non mi pare sia in linea con gli attuali protocolli che prevedono un allenamento di coordinazione intramuscolare alla settimana in stagione

The current study investigated the effects of 8 wk of strength-training cessation after 25 wk of strength training on strength- and cycling-performance characteristics.
Elite cyclists were randomly assigned to either 25 wk of endurance training combined with heavy strength training (EXP, n = 7...

The present findings suggest rapid decline of adaptations on termination of strength training during the first 8 wk of the competition period in elite cyclists. <- se interrompiamo l'allenamento di forza finisce anche il suo beneficio? Che sorpresona, mi pare più che logico e infatti è consigliata una seduta a settimana di forza massima tranne la settimana della gara di cat. A (giusto per riprendere Friel)
The molecular signaling of mitochondrial biogenesis is enhanced when resistance exercise is added to a bout of endurance exercise. The purpose of the present study was to examine if this mode of concurrent training translates into increased mitochondrial content and improved endurance...

Contrary to our hypothesis, the results demonstrate that concurrent training does not enhance muscle aerobic capacity and endurance performance in cyclists.

PurposeTo compare the effects of short-sprint training (SST) and heavy-strength training (HST) following a 4-week strength-training period on sprint and endurance capacities in well-trained cyclists.MethodsTwenty-eight competitive cyclists (age 29 ± 6 years) with maximal oxygen uptake () of 61.1...

SST led to a greater increase in average and peak power output on all sprint tests compared to HST, whereas HST led to a greater increase in maximal strength. No group differences were found in relative changes in endurance capacities

Despite these benefits, it was also reported that strength training could represent a detrimental stimulus for endurance performance if an inappropriate training plan has been prepared <- "if an inappropriate training plan has been prepared"..e quando invece è appropriato?
The phenomenon of concurrent training, or simultaneously training for strength and endurance, was first described in the scientific literature in 1980 by Robert C. Hickson, and although work that followed provided evidence for and against it, the interference effect seems to hold true in specific situations. At the molecular level, there seems to be an explanation for the interference of strength development during concurrent training; it is now clear that different forms of exercise induce antagonistic intracellular signaling mechanisms that, in turn, could have a negative impact on the muscle`s adaptive response to this particular form of training <- "In summary, when strength and endurance training are performed simultaneously, a potential interference in strength development may occur." quindi parla di migliorare la forza ma non la resistenza
