Single and Concurrent Effects of Endurance and Resistance Training on Plasma Visfatin, Insulin, Glucose and Insulin Resistance of Non-Athlete Men with Obesity

Abstract

The purpose of the present study was to investigate the effect of endurance (ET), resistance (RT) and concurrent training (CT) on plasma levels of visfatin, insulin, glucose and insulin resistance of non-athlete men with Obesity. It was a semi-experimental study. Thirty six men [age: 21.48 (0.25), and BF%: 27.39 (0.52)], voluntarily participated in this study after public announcement in university. Main inclusion and exclusion criteria was healthy (no physical illness and inability), obesity [based on WHO's definition body fat percentage (BF%) of over 25] and non-athlete (without regular training during week). They were randomly divided into three groups (n=12) for ET, RT and CT. For 8 weeks (3sessions/week), the candidates participated in ET (25-40 min at 65-85% of maximum heart rate), RT (5exercises, 6sets, intensity: 50-80% of one repetition maximum, volumes: 5, 8 and 12repetitions) and CT (one or a half-term ET and then RT with 3 sets). Blood samples were taken 48 h before the first training session and 48 h after the last training session. The BF% in ET was significantly less than that in RT (p0.01), and in CT, it was less than that for both ET and RT (p0.01). Plasma visfatin only, in CT was significantly less than that in RT (p0.01). Plasma insulin levels in CT were significantly higher than that in ET and RT (p0.01). Plasma glucose levels in CT were less than that in ET and RT, significantly (p0.01). Insulin resistance only in CT was less than that in ET significantly (p0.01). In general, the present study showed that maybe, CT have more effect on the body composition, glucose metabolism and insulin resistance adjustment, which can be effective in preventing obesity and adjusting adipocytokines such as visfatin.

Effects of Non-periodized and Linear Periodized Combined Exercise Training on Insulin Resistance Indicators in Adults with Obesity: A Randomized Controlled Trial

“…Clinically, the results of periodization are relevant, as they suggest signi cant reductions in insulin resistance indicators in a population at metabolic risk. In general, these positive effects can be effective in the prevention and treatment of obesity, as well as DM2 and other diseases, by promoting adjustments in adipocytokines and other metabolic markers[30].The strengths of this blind randomized clinical trial were the control of the aerobic training variables, the maintenance of the relative intensity in the NG, and the gradual increase of intensity in the PG over the mesocycles, both adjusted by the resting heart rate and considered a control method of low-cost. The progression of intensity and similarity in the training volume, is another strength, as it allows to verify the effects of different forms of periodization in the combined training program in an equal way.…”

Comparison of the Effect of Endurance, Strength, and Endurance-Strength Training on Inflammatory Markers and Adipokines Levels in Overweight and Obese Adults: Systematic Review and Meta-Analysis of Randomised Trials

“…Screening of the titles and abstracts excluded a further 33,344 articles and, therefore, 290 full texts were retrieved. Finally, 24 papers were included in the study [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 ], of which the two following papers related to the same study conducted on the same population and the same intervention but reported on the different outcomes: Nunes et al [ 47 ] and Martins et al [ 48 ]. Moreover, one manuscript was published in two journals [ 41 , 42 ].…”

“…All studies were designed as randomised trials and published between 2005 [ 45 ] and 2021 [ 23 ]. Most studies were performed in Asia (eight in Iran [ 17 , 18 , 20 , 37 , 38 , 41 , 42 , 44 , 46 ] two in Japan [ 19 , 45 ], and one in South Korea [ 24 ]); six studies were conducted in Europe (two in Poland [ 14 , 23 ], one each in Denmark [ 21 ], Finland [ 40 ], Greece [ 15 ], and Norway [ 43 ]); three in South America (Brazil [ 25 , 47 , 48 ]); and three studies were performed in Australia and Oceania (two in Australia [ 16 , 39 ] and one in New Zealand [ 22 ]).…”

“…All subjects included in the studies were overweight or obese, and were instructed not to change their dietary habits during the intervention period. The following parameters were used to defined excessive body weight: BMI [ 14 , 15 , 17 , 18 , 20 , 23 , 25 , 38 , 39 , 40 , 43 , 45 , 46 , 48 ], WC [ 14 , 21 , 22 , 23 , 43 ], %FM [ 14 , 19 , 23 , 24 , 37 , 47 , 48 ], and waist-to-hip ratio (WHR) [ 21 ]. The definition of overweightness or obesity was not provided in three studies [ 16 , 41 , 42 , 44 ].…”

Effects of Nonperiodized and Linear Periodized Combined Exercise Training on Insulin Resistance Indicators in Adults With Obesity: A Randomized Controlled Trial

“…An important detail is that the participants in this study [29] and ours were not previously trained, which enlarges and/or limits the zone of training regardless of the periodization model. In general, these positive effects can be effective in the prevention and treatment of obesity, as well as DM2 and other diseases, by promoting adjustments in adipocytokines and other metabolic markers [30].…”
