Gorostiaga, E. M., Izquierdo, M., Ruesta, M., Iribarren, J., Gonzalez-Badillo, J. J., & Ibanez, J. (2002). Effects of explosive type strength training on force production, sprint performance, endurance and serum hormones in soccer players. Medicine and Science in Sports and Exercise, 34(5), Supplement abstract 704.

Soccer players in two groups performed soccer and explosive-strength training (N = 10) or soccer training alone (control; N = 11) for 11 weeks.

The explosive-strength group significantly improved the low portion of the load-vertical jumping curve, the amount of serum testosterone, and in the first four weeks, 5-m sprint training. Endurance adaptation was not compromised.

Implication. Explosive-strength training combined with soccer training improved neuromusclar performance of explosive activities.
