Effects of strength training on endurance capacity in top-level endurance athletes

[Guest guest]

While looking up the article below shared by with the group, I bumped

into an equally-interesting one by the same author:

Aagaard P, Andersen JL. Effects of strength training on endurance capacity

in top-level endurance athletes. Scand J Med Sci Sports. 2010;20 Suppl

2:39-47.

Abstract:

The effect of concurrent strength (S) and endurance (E) training on adaptive

changes in aerobic capacity, endurance performance, maximal muscle strength

and muscle morphology is equivocal. Some data suggest an attenuated

cardiovascular and musculoskeletal response to combined E and S training,

while other data show unimpaired or even superior adaptation compared with

either training regime alone. However, the effect of concurrent S and E

training only rarely has been examined in top-level endurance athletes. This

review describes the effect of concurrent SE training on short-term and

long-term endurance performance in endurance-trained subjects, ranging from

moderately trained individuals to elite top-level athletes. It is concluded

that strength training can lead to enhanced long-term (>30 min) and

short-term (<15 min) endurance capacity both in well-trained individuals and

highly trained top-level endurance athletes, especially with the use of

high-volume, heavy-resistance strength training protocols. The enhancement

in endurance capacity appears to involve training-induced increases in the

proportion of type IIA muscle fibers as well as gains in maximal muscle

strength (MVC) and rapid force characteristics (rate of force development),

while likely also involving enhancements in neuromuscular function.
