Exercise immunology: involved components and varieties in different types of physical exercise
Physical exercise induces modifications in the immune system influencing either positively or negatively on health depending on its frequency, duration, and intensity. Acute or moderate physical exercise increases appreciably the immune cells, including cytokine levels while decreasing other components like NK cells, leading to a stronger response to pathogens as well as decreasing liability to allergic reactions. The expression of Toll-like receptors (TLR) is elevated as well, augmenting the positive effect. Exhaustive physical exercise, by contrast, modifies the immune system adversely. This review explores the links between physical exercise, immune cells and cytokines, and the immunological effects that have been studied by the performance of different kinds of physical exercise.

Validation and Reliability of a Novel Test of Upper Body Isometric Strength.

Abstract
The purpose of the present investigation was to examine the association of a novel test of upper body isometric strength against a 1RM bench press measurement.
Forty college age adults (n = 20 female, n = 20 male; age 22.8 ± 2.8 years; body height 171.6 ± 10.8 cm; body mass 73.5 ± 16.3 kg; body fat 23.1 ± 5.4%) volunteered for the present investigation. The participants reported to the lab on three occasions. The first visit included anthropometric measurements and familiarization with both the upper body isometric test and bench press exercise. The final visits were conducted in a randomized order, with one being a 1RM assessment on the bench press and the other consisting of three trials of the upper body isometric assessment. For the isometric test, participants were positioned in a “push-up” style position while tethered (stainless steel chain) to a load cell (high frequency) anchored to the ground.
The peak isometric force was consistent across all three trials (ICC = 0.98) suggesting good reliability. Multiple regression analysis was completed with the predictors: peak isometric force, gender, against the outcome variable 1RM bench press. The analysis resulted in a significant model (r2 = 0.861, p≤0.001) with all predictor variables attaining significance in the model (p<0.05). Isometric peak strength had the greatest effect on the model (Beta = 5.19, p≤0.001).
Results from this study suggest that the described isometric upper body strength assessment is likely a valid and reliable tool to determine strength. Further research is warranted to gather a larger pool of data in regard to this assessment.

Effect of Body Position on Force Production During the Isometric Midthigh Pull

Abstract
Beckham, GK, Sato, K, Santana, HAP, Mizuguchi, S, Haff, GG, and Stone, MH. Effect of body position on force production during the isometric midthigh pull. J Strength Cond Res 32(1): 48–56, 2018
Various body positions have been used in the scientific literature when performing the isometric midthigh pull resulting in divergent results.
We evaluated force production in the isometric midthigh pull in bent (125° knee and 125° hip angles) and upright (125° knee, 145° hip angle) positions in subjects with (>6 months) and without (<6 months) substantial experience using weightlifting derivatives. A mixed-design ANOVA was used to evaluate the effect of pull position and weightlifting experience on peak force, force at 50, 90, 200, and 250 ms.
There were statistically significant main effects for weightlifting experience and pull position for all variables tested, and statistically significant interaction effects for peak force, allometrically scaled peak force, force at 200 ms, and force at 250 ms. Calculated effect sizes were small to large for all variables in subjects with weightlifting experience, and were small to moderate between positions for all variables in subjects without weightlifting experience.
A central finding of the study is that the upright body position (125° knee and 145° hip) should be used given that forces generated are highest in that position. Actual joint angles during maximum effort pulling should be measured to ensure body position is close to the position intended.
