Individual development of performance in different running and jumping events together with changes in aerobic capacity and muscle strength over the years in a track-and-field athlete with regard to the focus of training. The results are percentages of performance at age 20–25. The track records represent official competition results, aerobic capacity a direct measurement of maximal oxygen uptake and muscle strength one repetition maximum in bench press (Suominen, unpublished observations)
