Association of sprint performance with ground reaction forces during the acceleration and maximal speed phases in a single sprint.

The speed with which all four phases of a short sprint (start, acceleration, maximum speed, and deceleration) are completed depends upon the amount of force applied during the pushing action away from the ground (ground reaction force – GRF) each foot strike, and the speed with which force is applied (rate of force production – …

Comparison of a push-up vs. bench press program for increasing strength and size

While the squat is regarded as the king of lower body exercises, the bench press ‘takes the cake’ for upper body exercises. The bench press is an excellent movement for developing strength, but there are several situations where this exercise may not be feasible. For example, use of the barbell may force the shoulder joint …

Effect of plyometric training vs. resistance training on strength and performance

Coaches often include a combination of progressive plyometric training and resistance training into strength and conditioning programs for their athletes. Plyometric exercises are typically performed immediately following the warm-up and before strength training exercises. Alternatively, plyometrics are sometimes performed on the practice field, separate from strength training workouts. However, time constraints and limited availability to …

Time-course of perceptual and neuromuscular recovery following resistance training

Programming resistance training during the in-season competitive phase can be quite challenging. This is because coaches need to ensure that athletes are receiving a sufficient training effect to maintain strength, power and muscle mass without compromising recovery and performance. Thus, picking the right days of the week to implement resistance training sessions that allows sufficient …

Heavy barbell hip-thrusts transiently improve 15 m sprint speed

Post-activation potentiation techniques are commonly used during training sessions to transiently enhance sprinting or jumping performance. The barbell back squat, deadlift and Olympic lifts tend to be the most commonly used potentiating exercises. Each of these movements predominantly involve vertical force production which would be optimal for vertical jumping and peak velocity sprinting. However, for …

Strength and power changes from long-term training in college volleyball players

Commitment to a structured and progressive strength and conditioning program can have a tremendous impact on the performance potential of an athlete. However, unless coaches keep records of changes in both performance markers and markers of strength and power, it is difficult to determine the magnitude of these improvements and if they’re related. For example, …

How does strength affect tackling ability?

Team sports are largely skill-based. All else being equal among teams, the more highly skilled team will typically prevail. This is why coaches are so adamant about technical development during training. Many would even argue that strength and conditioning training may be of little value to highly skilled athletes since they demonstrate success without participating …

Effect of inter-set antagonist muscle stretching on repetitions performed

Older studies in animal models suggested that extreme static stretching elicited substantial increases in muscle hypertrophy. Trainee’s have since been trying to find different ways to apply static stretching techniques for the purposes of building more lean tissue or improving resistance training performance. The inter-set period has been an area of focus for the implementation …

Does the barbell hip thrust improve 40 yard dash time?

Horizontal force production at the hip joint is a key component to acceleration speed during sprinting. While resisted-sprint training (e.g., sled-towing) has been shown to improve acceleration ability in athletes, there is minimal research on the effects of horizontal force producing weight-room movements on sprint performance. It’s been hypothesized that improving maximal strength in movements …

Recovery time is longer following high volume vs. high intensity resistance training

The necessary recovery time between training sessions depends largely on the type and quantity of work that was performed. Other factors such as training history and familiarity of the training session also matter. Novel training stimuli tend to make athletes more sore, despite reasonably low load and volume. Therefore, coaches need to be cognizant of …
