Endocrine response to acute resistance exercise in obese versus lean physically active men.
Article in European journal of applied physiology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeResistance exercise induces a host of endocrine responses that potentiate its effects on body composition and metabolism. Excess adiposity negatively affects some hormonal responses to exercise in sedentary men. This study compared the resistance exercise (RE)-associated growth hormone (GH), insulin-like growth factor-1 (IGF-1), and testosterone responses in lean vs. obese physically active men.
methodsTen healthy physically active obese males (body fat % 36.2 ± 4.03, age 24.6 ± 3.7 years, mass 104.5 ± 15.5 kg, height 178.8 ± 6.0 cm) were compared to ten lean counterparts (body fat % 12.7 ± 2.9, age 24.6 ± 3.7 years, mass 77.1 ± 6.4 kg, height 177.2 ± 4.8 cm). The muscular endurance RE protocol consisted of six sets of ten repetitions per leg of stepping onto an elevated platform (20 % of participant's height) while wearing a weighted-vest (50 % of participant's lean mass). Pre-, immediately post-exercise (IP), and three more blood samples were collected during the one-hour recovery.
resultsWhen accounting for baseline differences there were no group by time interactions for GH (p = 0.33); or LH (p = 0.52). Lean presented a trend towards significance for higher IGF-1 IP (p = 0.08) than obese. Testosterone IP was similar in obese and lean, but lower in obese than lean at 30 min into recovery (p < 0.01). AUC were lower in obese than lean for all hormones (p < 0.05 for all).
conclusionThese findings suggest that excess adiposity does not appear to negatively affect the immediate GH and T responses to RE in active males; but possibly negatively affects IGF-1. However, the baseline and integrated concentrations during recovery appear negatively affected by excess adiposity.
