Actually i've just got 'Periodization Training for Sports'. As you say, it is pretty heavy going but seems to be well grounded.
From my understanding so far;
Adaption phase (Horst's tactics and endurance) is more appropriate for athletes returning from an off-season in a team sport.
The hypertrophy phase is perhaps undesirable for climbers - better to gain strength without gaining bulk.
The recruitment phase would seem to be the most relevant to maximum strength gain for climbing. Bompa doesn't seem to give a re comended length for this phase but presumably it would be the primary mode for boulderers
Conversion would then be relevant if also wanting to increase power endurance for long boulders or short routes. If so, Bompa states 4 weeks as a minimum, 6 weeks more likely for making the adaptations required.
I don't really have any desire to peak at a particular time.. just want to continue getting better at boulders and short routes.
http://melhuish.org/climb/training.html describes a 'focused interval plan' where max strength/power and power endurance are trained continually though the emphasis shifts. Think i might use this as a base, something like:
4 weeks hard bouldering 2 days per week, milage 1 day
2 weeks hard bouldering 1 day, power endurance 1 day, milage 1 day
4 weeks power endurance 2 days, milage 1 day
2 weeks hard bouldering 1 day, power endurance 1 day, milage 1 day
I'll have to think about how best to work in a suitable amount of maintainace for max strength/power during the power endurance phase and vice versa.
