Relationships between physiological parameters and 5-km running performance were examined in 15 male runners (17.3 +/- 0.9 years). Running economy (RE) and blood lactate concentration ([BLa]) at 241.2 m/min, VO2max, velocity at VO2max (vVO2max), vertical jump height and muscle power, and isokinetic knee extension strength at 60degrees/sec and 240degrees/sec were measured. The participants' best 5-km race time over the last month of the cross-country season (16.98 +/- 0.76 min) was used in the analysis. The data were analyzed using Pearson correlation coefficients. Significant relationships to run time were observed for VO2max (r = -.53), RE (r = .55), and vVO2max (r = -.66), but not [BLa], isokinetic muscle torque, or vertical jump. Identifying the unique strength and power characteristics related to running performance in this age group is warranted. [ABSTRACT FROM AUTHOR] |
