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.
Sprinting Research Review (Part 6)
1) Multiple Sprint Exercise with a Short Deceleration Induces Muscle Damage and Performance Impairment in Young, Physically Active Males. Brandon P Woolley, John R Jakeman and James A Faulkner, Journal of Athletic Enhancement
This study has shown that a single bout of high-intensity multiple sprints elicit a similar amount of muscle damage to a single bout of drop jumps. More importantly, however, the results suggest that high-intensity multiple sprints has a greater impact on sprint performance. Athletes, trainers and strength and conditioning coaches should be aware of the prolonged impairment in specific performance characteristics (up to 72 hours) that may be evident following a single bout of high-intensity multiple sprints, and as such modify subsequent training sessions in line with such information. Future research should consider whether a repeated bout of multiple sprints leads to the attenuation of the indices of muscle damage and whether specific recovery methods should be utilised for athletes who have completed bouts of high-intensity multiple sprints.
2) Hydration status, sprint performance and physiological responses during repeated sprint ability (RSA) training session. RS Hamezah, N Juso. Journal of Physical Activity, Malaysia
As a conclusion, 15m RSA for 3 sets of 5 repetitions have no significant effect on hydration status, with sprint time performance cannot be said are influenced by hydration during an RSA session
3) Can analysis of performance and neuromuscular recoveries from repeated sprints shed more light on its fatigue-causing mechanisms? Olivier Girard, Franck Brocherie and Gregoire P. Millet
This article details fatigue mechanisms. Very technical but interesting.
4) Effects of seated and standing cold water immersion on recovery from repeated sprinting.
Jonathan D. C. Leederab, Ken A. Van Somerenbc, Phillip G. Bellbc, John R. Spenceb, Andrew P. Jewelld, David Gazee & Glyn Howatson. Journal of Sports Sciences.
These data suggest that increasing hydrostatic pressure by standing in cold water does not provide an additional recovery benefit over seated cold water immersion, and that both seated and standing immersions have no benefit in promoting recovery following intermittent sprint exercise.
5) Lower extremity kinematics of athletics curve sprinting. Tobias Alta*, Kai Heinricha, Johannes Funkena & Wolfgang Potthast.
These results extend the principal understanding of the effects of curve sprinting on lower extremity kinematics.
6) Effects of forward trunk lean on hamstring muscle kinematics during sprinting. Journal of Sports Sciences. Ayako Higashiharaa, Yasuharu Naganob, Kazumasa Takahashib& Toru Fukubayas
The present study provides significant evidence that a potential for hamstring muscle strain injury involving forward trunk lean sprinting would exist during the stance phase. The results also indicate that the biceps femoris long head and semimembranosus muscles are stretched during forward trunk lean sprinting while contracting eccentrically in the late stance phase; thus, the elongation load on these muscles could be increased
7) Groin Injuries in Athletes Development of Clinical Entities, Treatment, and Prevention. Per Hölmich (Doctorl Thesis) Denmark.
Excellent academic review of this important topic.
8) Effect of ischemic preconditioning on repeated sprint ability in team sport athletes. Neil Gibson. Journal of Sports Sciences.
Results suggest no benefit to team sport players in utilising IPC as a means of enhancing repeated sprint performance. A lower blood lactate response in female participants following IPC may suggest improved blood flow through vasodilation.
9) Fatigue affects peak joint torque angle in hamstrings but not in quadriceps . Journal of Sports Sciences.
This study showed after specific fatiguing task changes in hamstrings only torque/angle relationship. Hamstrings injury risk could depend on altered torque when knee is close to extension, coupled with a greater peak torque decrement compared to quadriceps. These results suggest the use eccentric based training to prevent hamstrings shift towards shorter length.
Written by Craig Donovan, a physiotherapy at Curtin University currently working in a rural hospital setting. He has a strong interest in research, particularly in the areas of pain and neurology. After recently completing a project looking into the association between the brain and pain, he is a strong believer in the importance of the brain in pain control.
The acronym of RICE is one of the most commonly used acronyms when it comes to treating acute injuries. The term was first used back in 1978 by Dr Gabe Mirkin, MD. But now the very same doctor who brought this acronym to our attention has wrote a post explaining that two of the key components of RICE (rest and ice) may actually delay healing.
