| Summary: | Purpose
To investigate the effects of combined strength and speed endurance (SE) training along with a reduced training volume on performance, running economy and muscular adaptations in endurance-trained runners.
Methods
Sixteen male endurance runners (VO
2
-max: ~60 ml kg
−1
min
−1
) were randomly assigned to either a combined strength and SE training (CSS;
n
= 9) or a control (CON;
n
= 7) group. For 8 weeks, CSS replaced their normal moderate-intensity training (~63 km week
−1
) with SE (2 × week
−1
) and strength training (2 × week
−1
) as well as aerobic high (1 × week
−1
) and moderate (1 × week
−1
) intensity training with a reduction in total volume of ~58 %, whereas CON continued their training (~45 km week
−1
).
Results
In CSS, 400-m and Yo-Yo intermittent recovery test performance was improved by 5 % (
P
< 0.01) and 19 % (
P
< 0.001), respectively, during the intervention period. Maximal aerobic speed was 0.6 km h
−1
higher (
P
< 0.05), and maximal activity of lactate dehydrogenase subunits 1 and 2 was 17 % (
P
< 0.05) higher after compared to before the intervention period. Time to exhaustion and peak blood lactate during an incremental treadmill test was 9 % (
P
< 0.05) and 32 % (
P
< 0.01), respectively, higher and expression of Na
+
–K
+
pump β1 subunit was 15 % higher (
P
< 0.05) after compared to before the intervention period. 10-K performance, maximum oxygen uptake and running economy were unchanged. In CON, no changes were observed.
Conclusions
Adding strength and speed endurance training, along with a reduced training volume, can improve short-term exercise capacity and induce muscular adaptations related to anaerobic capacity in endurance-trained runners. |
