Paul Hoffman has read and researched several research papers on sprinting and performance articles, so you don’t have to. If any of these articles interest you, feel free to research the case studies and methodology and come up with your own conclusions.
1. Acceleration capability in elite sprinters and ground impulse: Push more, brake less? by Jean-Benoît Morin, Jean Slawinski, Sylvain Dorel. Journal of Biomechanics 2015

In conclusion, this study shows that faster sprinters are those who produce the highest amounts of horizontal net impulse per unit body mass,and that vertical ground reaction force impulse is not related to 40m sprint performance.
Furthermore,within this higher amount of net horizontal impulse, faster sprinters are those able to “push more” (i.e. produce higher amount of propulsive horizontal impulse),but not necessarily to “brakeless” (i.e. produce lower amount of braking impulse),especially in the 0-20m section of the sprint.
2. DIFFERENCES BETWEEN THE ELITE AND SUB-ELITE SPRINTERS IN KINEMATIC AND KINETIC VARIABLES OF DROP JUMP. Milan and Nusret Smajlovi, Faculty of Sport, University of Ljubljana, Slovenia and Faculty of Sports and Physical Education, University of Sarajevo, Bosnia and Herzegovina
In drop jump, elite and sub-elite sprinters differentiated in the realisation of movement velocity in the eccentric and concentric phases (a difference between the groups is statistically significant p<0.05). Elite sprinters better utilise the stretch reflex, which allows them to more efficiently transfer elastic energy from first into second phase of take-off action.
3. A wearable real-time activity tracker. Ulf Jensen, Biomedical Engineering Letters. July 2015
A new product, Chronact, uses a new algorithm to measure Metabolic equivalents (MET).
4. Resistance Exercise: How Much Is Enough? MS Loveless, JM Ihm – Current Sports Medicine Reports, 2015.
This article reviews the literature on the components of a resistance exercise program and the recommendations for increasing strength and power in healthy adults.
Discusses a protocol to correlate static jump height and squat strength.
6. A simple method for measuring power, force, velocity properties, and mechanical effectiveness in sprint running. P Samozino, G Rabita, S Dorel, J Slawinski, N Peyrot. Scandinavian Journal. 2015
This is a very technical article that may lead to enhanced training evaluation.
7. Why do British sprinters underachieve? Daniel Cleather. St Mary’s University. 2015
Very thorough article that suggests young Elite sprinters are not developed well in Britain.
8. Brief Use of Steroids May Have Permanent Effects. University of Oslo. 2013
Once a cheater, always a cheater???
9. Running on Empty. Outside Magazine. Meaghan Brown. June 2015.
Excellent article on overtraining syndrome.
10. One hundred and fifty years of sprint and distance running – Past trends and future prospects. Martin Weissa, Alexandra Newmanb, Ceri Whitmorec & Stephan Weiss. European Journal of Sports Science.
Long-term trends suggest that:
- women will continue to run 10–20% slower than men,
- 9.50 s over 100 m dash may only be broken at the end of this century, and
- several middle- and long-distance records may be broken within the next two to three decades.
The prospects of witnessing a sub-2 hour marathon before 2100 remain inconclusive. Our results should be interpreted cautiously as forecasting human behaviour is intrinsically uncertain.
