Okej, hvala. Težko mi je bit brez konkretnega miganja, zato pa prehitevam. Si moram v glavi poštimat stvari, da je dolgoročno bolje počasi... Je pa res, da tik pred tem tekom niti pri enonožnem počepu ni bilo več čutit bolečine v kolenu, kajti če bi bila, tega poskusnega teka ne bi bilo.
Šprintam in hitro tečem na sprednji del stopala, počasen tempo npr. ogrevanje in izteki pa peta-prsti. Imam za sabo kar dosti šprintanja, pa počasi tečem vseeno na peto. Če mislim na to, lahko tečem tudi bolj na sprednji del stopala, ampak to ni moj "naravni" tek. Ta poskusni tek je bil seveda počasen, torej peta-prsti. Poznam teorijo o teku po sprednjem delu stopala (jo je težko ne poznat glede na agresivno oglaševanje "minimalističnih" copat

), ampak se najde tudi mnogo člankov proti tej teoriji. Npr. ena študija, ki izključuje povezavo foot strika s poškodbami:
No differences in self-reported Injuries or Performance Between Characterized Foot-strike Patterns amongst us army soldiers

There is currently little data characterizing Soldiers’ foot-strike (FS) patterns and
the potential relationship to running related injuries and performance. Literature has
characterized FS pattern distribution in marathon runners reporting a heel-strike (HS)
prevalence of 75%-94% in marathoners, with the remainder (6-25%) exhibiting a mid-
foot or fore-foot pattern (non heel-strike, NHS). Recent studies have reported that NHS
runners had fewer running related injuries and better performance.
PurPOsE:
To characterize the distribution of FS patterns in US Army Soldiers and
determine if FS patterns are related to self-reported running injuries and performance.
METhOds:
342 male Soldiers (24.7±5.1 y/o, 177.3+7.3 cm, 81.7+16.9 kg) from a
US Army Combined Arms Battalion completed a FS analysis and survey. Multiple
foot-strikes were recorded in the sagittal plane using a high-definition video camera
as each Soldier ran through a designated lane at a typical training pace. Soldiers
then completed a survey related to training habits and injury history.
The association between FS and the occurrence of a running-related injury was analyzed using a Chi-
squared test. Kruskal-Wallis test evaluated relationship between reported days that
training was modified due to injury as well as 2-mile run time between Soldiers with
NHS and HS patterns.
rEsuLTs:
13% of the participating Soldiers were characterized as NHS runners
and 87% were characterized as HS. There was no significant difference (p≥.05) in the
percentage of Soldiers reporting a running-related injury between those characterized
with a NHS versus a HS (55.6 v 51.0%). There were no significant difference between
NHS pattern versus HS pattern in the number of days training was modified due to
injury (21.8±78.4 v 13.9±49.5 days/yr), or 2-mile run time (14.8±1.6 v 14.8±1.7 min).
CONCLusIONs:
This cohort of US Army Soldiers demonstrated a prevalence of
HS similar to what has previously been reported in marathon runners. Based on this
preliminary analysis, neither FS pattern is advantageous in terms of impact on self-
reported, retrospective injury or performance

Ok, pač ena izmed veliko študij, ni nujno dober dokaz. Ampak če tako pogledaš, tudi med res vrhunskimi atleti jih ogromno pristaja na peto. Meddrugim tudi aktualni olimpijski in svetovni prvak v maratonu.
