Re: fatigue during power training

[Guest guest]

Hi ,

I know you requested articles on the acute onset of fatigue resulting from

power-type training, specifically, you seemed interested in what number of

repetitions, with load, does power output decrease.

I know of no 'articles' that may help, however, if I may, introduce a line

of thought, which may give you some direction (actually me too since I am in

a similar area of exploration right now.)

Bompa in " Periodization: Theory and Methodology of Training, " fourth

edition, suggests loads in the 50-80% (cyclic 30%+) range with a set volume of 4

to six sets and an RI [=rest interval] of 3 to 5 minutes to allow complete

recovery of energy systems and CNS (page 335.) Two pages later, from table 11.8

(Harre 1982) the number of suggested repetitions for both cyclic and acyclic

power development are set at 6 to 10.

Belgian R. Molette, according to Bompa, developed power by combining

weights and plyometrics. He advocated repetitions in the 6 range, working up to

12.

Repetitions would be halted in the acyclic and cyclic power exercises when

the bar speed reduced. Bompa suggests using a stopwatch.

Interestingly enough, I know Louie prescribes 3 repetitions per

set at 8 up to 12 sets for Compensatory Acceleration workouts at roughly 50%

intensity. Louie also suggests the use of a stopwatch. But with a

significantly shorter RI than Bompa suggests.

I would imagine then the parameters for optimal acyclic and cyclic power

output to be in the 3-6 rep range (or higher) before there is noted decrease in

starting and acceleration strength due to fatigue. On the safe side a RI of 4

to 5 minutes to ensure complete regeneration of all systems.

I am currently going to explore the glaring differences between the number

of repetitions that suggests and Bompa. The values deviate greatly,

even though intensity in some cases does not. I am not sure why specifically

(hence your desire for articles), but obviously fatigue plays a major role.

Perhaps, these deviations are more due to individual differences, such as

individual RFD, fiber recruitment, number of fibers. The list is long.

I hope I may have said something worthwhile and not just restated

something you are already well aware of. Let me know either way please and if

you have any other information to share on the topic.
