Concurrent endurance (E) and strength has caught the attention of many researchers due to
both leads to different adaptations, either cardiorespiratory or neuromuscular. It is well
known that combined strength and endurance may elicit conflictive adaptations e.g. the
loading from the previous training session could produce fatigue on the next session. Thus
the aim of this research is to investigate and compare the different cardiorespiratory and
neuromuscular adaptation in previously untrained men and women.
41 previously untrained males and females (21 men and 20 women) completed 24-weeks of
periodized combined strength and endurance training on different days. Both groups (males
and females) performed the same training protocol. All subjects were tested four times (-12,
0, 12 and 24 weeks)
The 24 weeks of combined endurance and strength training on different days on previously
untrained men and women resulted in significant cardiorespiratory and neuromuscular
increases. Maximal power output increases 17% (p<0.001) in men and 17% in women
(p<0.001) with no differences between groups. Maximum heart presented no significant
changes over the whole period. Vo2max increased 15% in men and 25% in women
(p<0.001). Men decreased 4%(p<0.05) the utilization of Vo2 at 200W. Women decreased
6% (p<0.01) heart rate at 50W, 6% at 75W(p<0.01) and 6% at 100W (p<0.01). Men decreased
8% at 75W (p<0.01); 9% at 100W (p<0.01); 10% at 125W (p<0.01) and 10% at 150W (p<0.01).
On the neuromuscular variables there were increases in 1RM leg press of 13% (p<0.001)
and 21% (p<0.001) in men and women respectively. Maximal isometric force increased
11% (p<0.001) in men and 19,4% (p<0.001) in women. Explosive isometric force (0-
500ms) increased 12% (p<0.001) in men and 26% in women (p<0.001). Men increased
countermovement jump in 6,7% (p<0.05) and women increased 12% (p<0.001). Women
decreased lactate utilization 18% at 100W (p<0.01) and 25% at 125W (p<0.001). Men
decreased 12% at 100W(p<0.01); 23% at 125W(p<0.001); 31% at 150W(p<0.001); 30% at
175W (p<0.01); 33% at 200W (p<0.05) and 31% at 225W (p<0.001).
