OBJECTIVES This non-randomised pilot study investigated the effect of eccentric quadriceps training on 17 patients (22 tendons) with painful chronic patellar tendinopathy. METHODS Two different eccentric exercise regimens were used by subjects with a long duration of pain with activity (more than six months). (a) Nine consecutive patients (10 tendons; eight men, one woman; mean age 22 years) ...

BACKGROUND Conservative treatment of patellar tendinopathy has been minimally investigated. Effective validated treatment protocols are required. OBJECTIVES To investigate the immediate (12 weeks) and long term (12 months) efficacy of two eccentric exercise programmes for the treatment of patellar tendinopathy. METHODS This was a prospective randomised controlled trial of 17 elite volleybal...

Newton, R.U., R.A. Rogers, J.S. Volek, K. Häkkinen, and W.J. Kraemer. Four weeks of optimal load ballistic resistance training at the end of season attenuates declining jump performance of women volleyball players. J. Strength Cond. Res. 20(4):955–961. 2006.—Anecdotal and research evidence is that vertical jump performance declines over the competitive volleyball season. The purpose of this stu...

Circulating testosterone is elevated acutely following resistance exercise (RE) and is an important anabolic hormone for muscle adaptations to resistance training. The purpose of this study was to examine the acute effect of heavy RE on intracrine muscle testosterone production in young resistance-trained men and women. Fifteen young, highly resistance-trained men (n = 8; 21 +/- 1 yr, 175.3 +/-...

PURPOSE Motor unit activity is coordinated between many synergistic muscle pairs but the functional role of this coordination for the motor output is unclear. The purpose of this study was to investigate the short-term modality of coordinated motor unit activity-the synchronized discharge of individual motor units across muscles within time intervals of 5ms-for the Vastus Medialis (VM) and Late...

BACKGROUND Economy, velocity/power at maximal oxygen uptake ([Formula: see text]) and endurance-specific muscle power tests (i.e. maximal anaerobic running velocity; vMART), are now thought to be the best performance predictors in elite endurance athletes. In addition to cardiovascular function, these key performance indicators are believed to be partly dictated by the neuromuscular system. One...
