Immunometabolic Responses after Short and Moderate Rest Intervals to Strength Exercise with and without Similar Total Volume

Abstract

This study investigated the influence of short and moderate intervals of recovery with and without equated volume during an acute bout exhaustive strength exercise on metabolic, hormonal and inflammatory responses in healthy adults. Eight physically active men (23.5 ± 3.1) performed three randomized sequences: Short (70% of 1 RM with 30 s of rest); Moderate (70% of 1 RM with 90 s of rest); and Volume-Equated Short (70% of 1 RM with 30 s of rest between sets with a repetition volume equal to that performed in Moderate). All sequences of exercises were performed until movement failure in the squat, bench press and T-bar row exercises, respectively. Glucose, lactate, testosterone, IL-6, IL-10, IL-1ra, and MCP-1 levels were assessed at rest, immediate post-exercise, and 1 h post. There was a main effect of time for testosterone (p < 0.001). The post hoc indicated differences between post-exercise and rest and post-1 h and post-exercise (p < 0.001). Lactate increased post-exercise when compared to pre and post-1 h (p < 0.001) and maintained higher post-1 h in relation to rest. IL-6 was greater post-exercise than rest (p = 0.045) and post-1 h and rest (p = 0.020). IL-10 was greater post-exercise (p = 0.007) and post-1 h (p = 0.002) than rest. IL-1ra increased post-exercise in relation to rest (p = 0.003) and MCP-1 was greater post-exercise than rest (p < 0.001) and post-1 h (p = 0.043). There were no significant differences between conditions or interaction. Thus, both short and moderate intervals of recovery induced greater metabolic, hormonal and inflammatory responses after acute bout of exhaustive strength exercise in healthy adult.

Acute Strength Exercise Decreases Satiety by Modifying Blood Cytokines Levels in Physically Active Men

“…The results of the 1-RM test showed low mean values for the squat exercise compared with the data obtained by Pearcey et al 23 , who studied a similar population of young men. For the bench press exercise, the results were similar to those obtained by Calatayud et al 24 and higher than the values observed for bench press and T-bar row exercises performed by young men studied 20 .…”

“…The load was increased gradually (15%) during the test until the participants were no longer able to complete the movement, allowing 3-5. A rest interval of 5 min was allowed between attempts 20 . No rest was allowed between the concentric and eccentric phases of the movement, and the participants were encouraged verbally to exert maximum effort.…”

Interleukin‐10 responses from acute exercise in healthy subjects: A systematic review

“…To investigate the effects in IL‐10 behavior after acute exercise, the results were grouped according to the type of exercise. Four articles studied the effects of exercise and IL‐10 on strength (Agostinete et al, ; Gerosa‐Neto et al, ; Peake, Nosaka, Muthalib, & Suzuki, ; Rossi, Gerosa‐Neto, Zanchi, Cholewa, & Lira, ), three on continuous running versus intermittent running performed on treadmill (Cabral‐Santos et al, ; Dorneles et al, ; Ghafourian, Ashtary‐Larky, Chinipardaz, Eskandary, & Mehavaran, ), one on cycling ergometer (Cullen, Thomas, Webb, & Hughes, ;) and four on strenuous exercise – lasting at least 3 hr of outdoor long distance race (which the runners were allowed to choose their own speed) associated or not to other type of exercise (Comassi et al, ; Kaoru, Suzuki, Yoshitani, Shiraishi, & Kometani, ; Krzemiński et al, ; Nickel et al, ).…”

“…The metabolic cost of this type of exercise is lower compared with aerobic exercise and consequently, the IL‐10 levels is less pronounced. Agostinete et al () utilized strength exercises with 70% one maximum repetition‐1RM and observed increased levels of IL‐6 and IL‐10 immediately after the exercise which remains elevated post‐1hr than basal levels. The others studies analyzed did not show this dynamic, although it was observed an increase of IL‐10 in the period of exercise recovery…”

“…The dynamics of this type of exercise is influenced by different variables such as intensity, workload, number of repetitions, interval between sets, and the size of muscle mass involved in muscle contraction. The metabolic cost of this type of exercise is lower compared with aerobic exercise and consequently, the IL-10 levels is less pronounced Agostinete et al (2016). utilized strength exercises with 70% one maximum repetition-1RM and observed increased levels of IL-6 and IL-10 immediately after the exercise which remains elevated post-1hr than basal levels.…”
