Temfemo, A, Carling, C, and Ahmaidi, S. Relationship between power output, lactate, skin temperature and muscle activity during brief repeated exercises with increasing intensity. J Strength Cond Res 24(X): 000-000, 2011-The aim of this study was to assess the relationship between power output, lactate, skin temperature, and quadriceps muscle activity during brief repeated exercise with increasing intensity. Eighteen regional level soccer players (age 24.5 ± 3.8 years) were selected after a test of maximal exercise capacity to participate in 2 force velocity (Fv) exercise tests separated by 3 days. The tests were done to examine the reliability of variables measured in the selected subjects during this type of task. During each Fv exercise test, data on power output, heart rate (HR), skin temperature, blood lactate accumulation, the root mean square (RMS), and the mean power frequency (MPF) of the surface electromyography of the superficial quadriceps muscle were collected. Results showed a significant correlation between power output and HR, skin temperature, blood lactate accumulation, and RMS. However, no association was observed with MPF that informs on the level of fatigue and power output. Thus, the result of this study may suggest that the Fv exercise test is not a fatigability test.
