Exercise and Recovery Responses of Lymphokines to Heavy Resistance Exercise

2000

To examine the effect of dynamic resistance exercise on the response patterns of lymphokines, 10 strength-trained men (21.7 +- 0.6 y) performed 2 resistance exercise protocols, high force (HF) and high power (HP), of equal total work (HF 5 33.0 +- 2.5 kJ; HP 5 33.3 +- 2.7 kJ) in a randomized order separated by 1 week. Resting blood samples were obtained preexercise and 0 (R-0), 15 (R-15), and 240 (R-240) minutes postexercise. Plasma lactate significantly (p < 0.05) increased from baseline for both protocols; however, concentrations were higher in response to the HF protocol. Plasma interleukin- 2 (IL-2) concentrations were significantly decreased from baseline at R-15 following the HF proto…

Leukocyte β2-Adrenergic Receptor Expression in Response to Resistance Exercise

2011

Purpose: Epinephrine and norepinephrine mediate interactions between the neuroendocrine and the immune systems to alter immune cell activity. Although both systems respond to exercise stress, less is known about how they interact in response to such stress. The purpose of this investigation was to examine s2-adrenergic receptor (s2-ADR) expression on circulating leukocytes to an acute bout of resistance exercise in men and women. Methods: Resistance-trained men (n = 8; mean ± SD age = 24.63 ± 5.07 yr, body mass index = 26.09 ± 2.21 kg·m-2) and women (n = 7; age = 22.13 ± 3.09 yr, body mass index = 22.63 ± 2.03 kg·m-2) performed an acute resistance exercise protocol (six sets of five-repetit…

Glucocorticoid receptor expression on human B cells in response to acute heavy resistance exercise.

2011

&lt;i&gt;Objective:&lt;/i&gt; To examine glucocorticoid receptor (GCR) expression on B lymphocytes in response to an acute bout of resistance exercise. &lt;i&gt;Methods:&lt;/i&gt; Using a within-subject design, resistance-trained women (n = 7; age: 22.13 ± 3.09 years; height: 1.69 ± 0.084 m; body weight: 65.60 ± 10.01 kg; body mass index: 22.63 ± 2.03 kg/m&lt;sup&gt;2&lt;/sup&gt;; means ± SD) and men (n = 8; age: 23.28 ± 4.26 years; height: 1.73 ± 0.086 m; body weight: 73.93 ± 12.71 kg; body mass index: 24.51 ± 2.61 kg/m&lt;sup&gt;2&lt;/sup&gt;; means ± SD) performed an acute resistance exercise protocol (6 sets of 5 repetition maximum heavy squats) and a control test in a balanced, randomi…
