Effects of Isokinetic versus Isotonic Training and its Cessation on Total Leukocytes and Lymphocytes Count in Adolescent State‑level Weightlifters

Background: the study investigated the effects of isokinetic versus isotonic training among adolescent state‑level weightlifters in terms of total leukocytes, total lymphocytes, and its subsets following 24 sessions of training program and a month following training program cessation. methods: nineteen adolescent state‑level weightlifters were assigned into isokinetic or isotonic groups. all participants were recruited from a pool of weightlifters with standardized training program provided by their coach. series of immunological tests were carried out before the commencement, immediately upon the completion, and a month after the cessation of the additional training program to evaluate total leukocytes and lymphocytes count. results: the results revealed a significant time and group interaction and main effects of time on mean total leukocytes (p < 0.05). mean total leukocytes count at posttest decreased in both groups. in isotonic group, it was further decreased following 1 month of training cessation (p < 0.05) but not in the isokinetic group. however, the decrement was not high and the values were in the normal range. no significant time and group interaction was observed in total lymphocytes and its subsets count. conclusions: eight weeks of isokinetic and isotonic additional training with emphasis on shoulder joint only affect mean total leukocytes count in state‑level adolescent weightlifters.
