Purpose: The purpose of this study was comparing the effects of massage and rest on fatigue and recovery of strength following exhaustive concentric contraction.
Material and Methods: In this research, 10 subjects (age 20.7 ± ۰٫۹۴ yrs, body mass 59.5 ± ۵٫۸۹ kg, height 173 ± ۳٫۶ cm ,body mass index 20.5 ± ۱٫۳۷ m/cm 2 ) from 60 male, non-athlete students of Ferdowsi University of Mashhad, participated voluntarily and based on the specific inclusion/exclusion criteria of the study. The subjects participated in two testing sessions during a week (with an interval of 48 hours between the first and second session).
Subjects did warm-up at the beginning of each session. In the first session, maximum strength of quadriceps was measured by leg extension machine. In the second session (the rest session) the participants initially did exhausting concentric contractions with 50% of their maximum strength after the warm-up, then quadriceps muscle strength was measured before and after 6 minutes of rest, using evaluation instrument of isometric strength in 90 degree knee angle. In the third session the participants received classical massage techniques instead of resting for 6 minutes. The data regarding fatigue and strength recovery, between passive rest and massage sessions have been analyzed using paired sample t-test. All the data analyses were done using SPSS software. P
