Good lord–130km/hr? No way a person should be outside in those winds! Gale-force winds blow things about. Living in the Pacific, I knew of someone who was killed when she was struck by a stop sign that was torn away from its post and blown at her at something over 100km/hr.
Okay, as far as track training: Using natural wind is fine. A particularly useful session can have the runner keeping the wind to her/his back for one set of repetitions; then a set into the wind (resistance training); then a final set with the wind to one's back (leaving the increased speed as the final neural imprint).
The problem with using very strong winds is that they can alter the sprinter's mechanics markedly. And this is the same objection that many have to using assisting devices for overspeed. Too great a jump over the athlete's unaided top speed will tend to produce a braking (not "breaking") force in the stride, as the foot lands well in front of the runner's center of mass.
My athletes used overspeed for years and loved it, and their results certainly suggested that it was not harmful (multiple conference championships/all-Americans in the speed events, 800m runner who went from 2:04 to 1:55 in two years, etc.). However, we emphasized three things:
1) A *slight* increase over one's unaided top speed, perhaps as much as would be encountered with the wind to one's back on a breezy day.
2) A complete emphasis on achieving the speed through higher turnover. I do suspect that a somewhat-lengthened stride also occurred, but because our concentration was completely on greater turnover–more steps per second–there was no problem with developing an overstride that carried over into unaided running. Again, this increase in turnover was only possible because we stayed slightly over the athlete's unaided top speed. Had the athletes gone considerably above that speed, they would have had to overstride in self-defense!
3) The higher turnover (which we were able to document) was possible because we emphasized certain features of correct (whether aided or unaided) sprinting technique: relaxed elbows (triggering) relaxed knees (allowing) full flexion at the knee (resulting in) a shorter lever, with the swinging foot stepping through above the knee of the supporting leg; a feeling of lightness or quickness (promoted by) reduced time that each foot was on the track (coached by emphasizing) running over the track rather than on[/u] it; and by the active backward movement of the foot as it struck the track.
If anything, we felt that overspeed work led to fewer injuries. It certainly promoted an increase in (so-called) dynamic flexibility–flexibility at high speed; but we also used a steady program of PNF stretching, to build strength as well as flexibility at the limits of the range of motion, and we avoided overspeed if the athlete had soreness from previous work. Note: this definitely applies to sore calves, as well, because the calves assist in bending the knee during a sprinting stride!
Bottom line: we had good results and very few injuries with overspeed work. And the kids loved it, which should not be overlooked. Face it: sprinters come out for track so they can learn to run fast. Few experiences in the sport can bring the sprinter more pleasure than running faster than s/he has ever run before. And treating overspeed as a "treat"–as a reward for complete preparation–certainly was great motivation for getting the kids to do their strength work, their PNF, their stride drills, proper warmups and cooldowns, etc.
