- Description: BLUF Training for the speed component of sprinting with resistance training requires the use of high velocity horizontally-directed exercises such as speed-bounding and sled sprinting. ABSTRACT The purpose of this article was to evaluate selected resistance training exercises in relation to the force-velocity continuum, with the application to sprinting performance in team sport athletes. The analysis of exercises was done by focussing on the peak velocities reached and comparing this to velocities in sprinting. Many popular resistance training exercises such as jump squats and modifications of the Olympic lifts are used to enhance the explosive muscle qualities required for sprinting. A common characteristic of these exercises is that force application and corresponding body/bar movement is directed vertically upward against gravity. This means that despite using light loads or no extra load, the resulting movements are relatively slow (less than 5 s-1). For example, adding any load to jump squats generally decreases power output compared to jumps with only bodyweight. Therefore, vertically-directed exercises should be considered as being strength-dominated. However, sprinting involves relatively short muscular contractions and considerably faster movement, even over short distances of less than 20 m. To prescribe exercises that are closer to the speed end of the force-velocity continuum, horizontally directed exercises are preferable. Examples include sled sprints and plyometric exercises such as speed-bounding. In a periodised program designed to enhance sprinting performance, vertical exercises such as jump squats and power cleans should be considered as strength-dominated, whereas horizontal exercises should be prescribed when speed qualities need to be emphasised such as in a pre-competition phase.

- Description: The effect of including a series of isometric conditioning contractions to the rowing warm-up on 1,000-m rowing ergometer time trial performance. J Strength Cond Res 26(12): 3326-3334, 2012- Rowing requires strength, power, and strength-endurance for optimal performance. A rowing-based warm-up could be enhanced by exploiting the postactivation potentiation (PAP) phenomenon, acutely enhancing power output at the beginning of a race where it is needed most. Minimal research has investigated the effects of PAP on events of longer duration (i.e. 1,000-m rowing). The purpose of this research was to investigate the effects of PAP on 1,000-m rowing ergometer performance through the use of 2 different warm-up procedures: (a) a rowing warm-up combined with a series of isometric conditioning contractions, known as the potentiated warm-up (PW), and (b) a rowing warm-up only (NW). The isometric conditioning contractions in the PW were performed by "pulling" an immovable handle on the rowing ergometer, consisting of 5 sets of 5 seconds (2 seconds at submaximal intensity, and 3 seconds at maximal intensity), with a 15-second recovery between sets. The 1,000-m rowing ergometer time trial was performed after each warm-up condition, whereby mean power output, mean stroke rate, and split time were assessed every 100 m. Ten Australian national level rowers served as the subjects and performed both conditions in a counterbalanced order on separate days. The PW reduced 1,000-m time by 0.8% (p > 0.05). The PW improved mean power output by 6.6% (p < 0.01) and mean stroke rate by 5.2% (p < 0.01) over the first 500 m; resulting in a reduction of 500-m time by 1.9% (p < 0.01), compared with the NW. It appears that the inclusion of isometric conditioning contractions to the rowing warm-up enhance short-term rowing ergometer performance (especially at the start of a race) to a greater extent than a rowing warm-up alone. © 2012 National Strength and Conditioning Association.
