Training "On Cycle", Done Right - Women See Much Better Results When Periodization is in Line W/ Menstrual Cycle
 |
| Yes, I could have exploited the ambiguity and called this article "Training 'On Cycle', Done Right - Women See Much Better Results When Periodization is in Line W/ Their Period", but let's be honest: This is a science website and that's neither scientific, nor actually funny, is it? |
For many trainers, however, the estrous cycle is still a closed book. "Can you train, or not!?" Especially male trainers are not just insensitive when they ask their protégées this question, they may also be missing out on a chance to maximize their clients' training progress. That's at least what a recent 4-months study from the Umea University in Sweden (Wikström-Frisén. 2015) suggests.

| Figure 1: Relative changes in lean mass (DXA data), measures power and strength (torque) in 59 trained women in response two weeks of frequent leg-training in the first or second two weeks of their estrous cycle (Wikström-Frisén. 2015). |
What about women on oral contraception? The scientists recruited 32 young women on oral contraceptives and 27 women who didn't use oral contraceptives and a re-analysis of the data in Figure 1 didn't show significant inter-group differences between the two groups. In other words, the data in Figure 1 and thus the main findings are relevant for "all" resistance training young women, irrespective of whether they're taking contraceptives, or not. The only difference is that you go by the contraceptive (CC), instead of the estrous cycle and place the high frequency training period in the first, not the last two weeks of the CC cycle.
"Meaningless changes", however, are not meaningless results. In fact, the exact opposite is the case. These results tell trainers and female trainees, alike, that abandoning their protégées / their own- regular non-periodized training, i.e. three leg training workouts per week that consisted of leg presses and leg curls (3x sets @ 8-10RM, 1-2 minutes rest between sets; progressive increase of weight by 2-10% whenever the subjects could perform 3x10 reps with a given weight)
for 4-months and switching to a periodized 2-week high- vs. 2-week low-frequency training, where they would perform the same 48 workouts in either
- high-frequency first cycles, i.e. 5 workouts per week in the first two weeks, 1 workout per week for the last two weeks of each menstrual / contraceptive cycle, or
- high-frequency last cycles, i.e. 1 workout per week in the first two weeks, 4 workouts per week for the last two weeks of each menstrual / contraceptive cycle,
would have beneficial effects on their progress only if they increase the frequency during the early phase of the cycle.

| Figure 2: Comparison of the relative changes in the periodization group (high frequency in the first two weeks of the menstrual / CC cycle) vs. control group (three workouts per week for 4 months | Wikström-Frisén. 2015). |
Ok, if you compare the periodization group to the control group which kept the regular "three workouts per week"-frequency (see Figure 2, green bars) was maintained, the "advantages" of periodizing "correctly" are not as pronounced as they are in comparison to doing it the "wrong" way. Even though, only the hamstrings appear to benefit to a large extent from periodization, though, benefits exist.
What's even more important, though, is the simple, but really important revelation (or for the few of you who have read about this before e.g. in Reis et al. (1995) "confirmation") that a woman's menstrual and similarly her contraceptive cycle must be aligned to her training schedule. Obviously, the implications will have to be further explored in future studies. Studies, of which I hope, that they will be using smarter periodization schemes which acknowledge that training only once a week is simply not enough... ;-)

With that being said, I personally think of this study as one study in a series of studies that will hopefully elucidate how women can adapt their training regimen to the repetitive changes in the hormonal milieu of their bodies.
If we are honest with ourselves, the fact that Wikström-Frisén's results come as a surprise to most of us is only further evidence of how wantonly exercise scientists and trainers, alike, have hitherto neglected the peculiarities of the female physiology and endocrinology | Comment on Facebook!

Overreaching A Promising, But Tricky Training Strategy - Here's How it Rewards Pains & Effort With 5% Higher Peak Power Gains After 12 Workout vs. Training W/ Adequ. Rest

| No rest(-day) allowed - at least during the short (!) overreaching phase you will be training through the pain & fatigue if you are determined to succeed. |

- the overreaching-detraining (OR-DT), in which the subjects performed maximal cycle sprint training on 12 consecutive days, followed by 6 days of detraining (=no exhausting physical activity at all | like 12xA - 6xR) and
- the control (CON) group, in which a complete day of rest was provided after every 2 successive training days (like A-A-R-A-A-R- [...])
For both groups, the training sessions consisted of 2–4 sets of 30 s of maximal pedaling on an electromagnetic cycle ergometer (Powermax V3, Konami Sports & Life Co., Ltd., Tokyo, Japan). Each set was followed by a 7-min rest period. The resistance for the first set was set 7.5% of BW, and it was reduced to 5.0 % of BW for the subsequent sets. During each training session, the subjects were verbally encouraged and instructed to give their maximal effort.

What do we already know about overreaching? Unfortunately, we don't know how to make sure it's not turning from overreaching to overtraining, but that's one of the many questions scientists will still have to answer (Mackinnon. 2000). What we do know, though, is supplements like creatine or 0.4g/kg body weight EAAs and likely whey can help conserve the performance during and thus improve the outcome after overreaching periods (Ratamess, 2003; Volek. 2004). We also know that overreaching attenuates the testosterone response to workouts in untrained, but not trained individuals and A.M. cortisol, but no the cortisol response to workouts in both trained and untrained subjects (Fry. 1994). Both, the amount of creatine kinase and glutamate in the blood which can be used as indicators of muscle damage increase during periods of overreaching (Halson. 2003). Lastly, the changes in the immune markers indicate that athletes may be particularly prone to infections during phases of extra-(=too)intense training (Gleeson. 2002).
That's truly unfair, but it's the reality of competitive sports (*). After all, you have the choice of training like the control group before the event to make sure that you're full of sap or, alternatively, to follow the OR-DT program and start on game day maximally refreshed and with an adaptational bonus in the peak-power domain that may make all the difference when you're sprinting towards and over the finish line (see Figure 2).  |
| Figure 2: Relative peak power and mean power during the pre- and post-test days as well as on the differently timed training days in the OR-DT and CON group (Hasegawa. 2015). |
 |
| The supercompensation of phospho-creatine stores may also explain the power gains in the overreaching + detraining group (Haegawa. 2015), but still, do not underrate the ergogenic benefits of the stress hormone cortisol - it's on the WADA list for very good reasons, esp. wrt endurance sports! |
For regular waredownloadsoft readers this should be as unsurprising, though as the fact that the OR-DT's ability to maximize their cortisol response at the post test is probably (one of the) reasons that they kicked their competitions a$$ when it comes to peak performance... unbelievable?

Well, take a look at the endurance performance of the cyclists in Katia Collomp's 2008 study (Figure 3, right) - what did almost double the endurance of her subjects? Yes, it was synthetic cortisol - prednisolone at a dosage of 60mg to be precise. And just as it is important to point out that these benefits are restricted to acute short term increases, it is noteworthy, that, in the Hasegawa study, the cortisol response during the over-reaching phase was as, if not more blunted as it was in the CON group.

Unfortunately, there's also asterisk (*) number two you will find right after the information that we are not dealing with professional athletes. That's a problem, because it is unlikely that the ordeals a seasoned athlete can sustain and still gain are the same as those of a rookie. This does not mean that everyone needs more or longer hammering, though. In fact, many athletes are chronically overtrained. For them (Matos. 2011), the 6-day rest may be a good idea; to try to increase their performance by strategic overreaching,on the other hand, would be madness and obviously counter-productive.
