dc.description.abstract | Purpose: To compare the effects of short-sprint training (SST) and heavy-strength training (HST) following a 4-week strength-training period on sprint and endurance capacities in well-trained cyclists.
Methods: Twenty-eight competitive cyclists (age 29 ± 6 years) with maximal oxygen uptake (www.frontiersin.org) of 61.1 ± 5.9 mL⋅min–1⋅kg–1 participated. After a 4-weeks preparation strength-training period, the participants were randomized to add either HST or SST to their usual endurance training for the subsequent 6 weeks. Body composition, www.frontiersin.org and power output at blood lactate concentration ([La–]) of 4 mmol⋅L–1, as well as a 100 min cycling test including 6 and 30-s sprints, 60 min cycling at [La–] of 2 mmol⋅L–1 and 5-min all-out cycling were performed before the 4-week preparation strength-training period, and before and after the 6-week intervention period. In addition, 1 repetition maximum (RM) in half-squat and 55-m maximal sprints on the cyclists’ own bikes were measured before and after the 6-week intervention.
Results: SST was superior to HST in 6-s sprint performance, both in a fresh state (4.7 ± 2.6% vs. 1.1 ± 3.5%) and after prolong cycling (6.1 ± 1.8% vs. 1.8 ± 4.2%), in 30-s sprint (3.7 ± 2.8% vs. 1.3 ± 2.5%) and in 55-m seated sprint on own bike (4.3 ± 2.1% vs. 0.2 ± 1.8%) (all p < 0.002). HST induced a larger 1RM improvement in the half-squat test than SST (9.3 ± 3.6% vs. −3.9 ± 3.8%; p < 0.001). No group differences were revealed in the 5-min all-out test, www.frontiersin.org, power output at 4 mmol⋅L–1 [La–], or in gross efficiency.
Conclusion: SST led to a greater increase in average and peak power output on all sprint tests compared to HST, whereas HST led to a greater increase in maximal strength. No group differences were found in relative changes in endurance capacities. Altogether, our results show a high degree of specificity in the adaptations of both SST and HST. | nb_NO |
