PURPOSE: To examine the leukocyte response to an acute squat protocol while wearing knee wraps versus no knee wraps. METHODS: 7 resistance trained men (22.3±3.6 yrs, 69.1±1.12 in, 77.9±5.4 kgs BW; 1-RM = 153.3±26.8 kgs) completed four experimental visits. Participants were asked to complete 8 sets of 10 repetitions of the squat at 70% of their 1-RM. Blood samples were collected prior to exercise (PRE), as well as immediately (IP), one hour(1H), 24 hours (24H) and 48 hours (48H) after exercise. Blood samples were analyzed via hematology analyzer for leukocyte count (WBC), lymphocyte (LY), monocyte (MO) and granulocyte (GR) number (#) and ratio (%). Data were analyzed using a condition x time repeated measures ANOVA. RESULTS: Significant main effects of time were observed for LY% (pp2=0.1800), LY# (pp2=0.923), MO# (pp2=0.652), GR% (pp2=0.793) and GR# (pp < 0.05), while GR% was reduced at IP compared to PRE, 1H and 24H (pp < 0.05) compared to PRE, 24H, and 48H. GR% and GR# were also both greater at 24H versus 48H values (pp=0.013). CONCLUSIONS: Resistance exercise elicits an immediate increase in circulating leukocytes, primarily through increases in LY%.

PURPOSE: Examine leukocyte response to an acute squat protocol while wearing knee wraps versus no knee wraps. METHODS: 7 resistance trained men completed four visits. Participants completed 8x10 repetitions at 70% of 1-RM. Blood samples collected before exercise, immediately post, one hour, 24 and 48 hours after exercise. Blood analyzed for leukocyte count, lymphocyte, monocyte and granulocyte number and ratio. RESULTS: Significant time effects observed for LY%, LY#, MO#, GR%, and GR#. LY%, LY#, and MO# increased at IP across time, while GR% reduced at IP across time. GR# increased at 1H compared to PRE, 24H, and 48H. GR% and GR# were greater at 24H versus 48H, while LY% at 24H were lower than 48H. CONCLUSIONS: Resistance exercise elicits an immediate increase in circulating leukocytes.
