|"Men are different women, too..." We all know that, but can we still train together or will women have to do cardio first, while men would be better off starting out lifting weights?|
60 minutes LISS + 45 min leg circuit or vice versa - what's best?
The intention of the researchers was to "to examine the acute exercise induced serum hormone and neuromuscular responses and the time course of changes during recovery in response to a combined strength and endurance training session in recreationally endurance trained male and female runners and whether this response would differ if the participants started their workout with a ...
- steady state running exercise at an intensity between each subject’s previously determined individual lactate threshold (LT) and respiratory compensation threshold (RCT) for 60 minutes, or
- a circuit leg workout with 2 minutes rest between sets that implemented both maximal and explosive strength exercises at loads of 70–85% of the individual 1RM for three sets of 5–8 repetitions, with the final repetition of each set being performed to "near failure" and explosive strength exercises of 8-10reps at a maximal velocity using only 30-40& of the 1EM load on the bilateral leg press (3 sets maximal and 3 sets explosive), the squat (3 sets maximal), loaded squat jumps (3 sets explosive), and calf raises (2 sets maximal).
|Figure 1: Change in maximal voluntary contraction (MVC) in men (left) and women (right) during, immediately after and in the recovery period after the endurance first (ES) and strength first (SE) workouts (Taipale. 2013)|
"The relative loading-induced decreases (D%) in strength between ES and SE differed significantly at mid in men (p<0.001). The relative decreases (D%) in strength in men and women were similar at MID; however, at post, a significant difference between ES men and ES women was observed. The absolute rate of force development (RFD) decreased during both loadings in ES and SE men (at post -19%, p< 0.001 and -22%, p = 0.003, respectively)." (Taipale. 2013)So once again, the "fairer sex" had an "unfair" advantage, as the rate of force development of the women did not decrease significantly after either the ES or the SE trial. However, it was on ony after the "endurance first" (ES) trial that this effect reached statistical significance.
Level playing field? You must be kiddin' the girls are on dope... ah estrogen ;-)
A similar advantage was observed for the recovery of the initially equally decreased maximum voluntary contraction (MVC) in men and women. Contrary to the ladies who bounced back to normal within the first 24 hours, the MVC of the men remained significantly below the baseline levels in both the strength- (ES) and endurance first (ES) arms of the study 24 h after the endurance first trial (-14% and -15%, respectively) and was still below baseline 48 h post (p < 0.01 -11%).

"Men better start with strength training. Women do whatever they like?! "
The faster recovery after the strength first, endurance second (SE) trial, as well as the 343x higher GH levels after the in this arm of the study appear to speak in favor of doing your strength training first, before you hop onto a recumbent bike or treadmill and add in another 40-60min of light intensity steady state training (LISS), if you are a man! In the fortunate case that you are a member of the estrogen driven fairer sex (= a woman ;-), the study at hand appears to suggest that it would not really make much of a difference, whether you hit the weights first or second.

So, which of the myriad of studies do we trust?
If it were not for one major glitch in the study at hand, I would probably end this article on the note that the singularly long follow up period in the study at hand would clearly suggest that the results Taipale et al. generated in the course of their experiment had more practical value (we all know about the fallacy of the narrow minded focus on the immediate post-workout endocrine response; don't we?) the fact that they did not control for the workload is a real bummer.
Imagine the guys simply lifted way more weight in the strength first, endurance second trial - wouldn't an increased GH response to an identical endurance workout with way more depleted glycogen stores actually be what you would have to expect? Also, we all know that when you put men and women together in the gym, the former train until they drop, while the latter do as they are told and take their time looking at the sweaty guys while fumbling around with the weights... ok, that's a cliché, but there is way more than just the splinter of truth that's at the bottom of every of these commonly held prejudices.

And don't forget, a glycogen depleting cardio session before your strength workout could increase the expression of the muscle building isoform PGC-1a (learn more)
