“…This is consistent with our previous data showing no change in resting cortisol at moderate altitude (Woods et al 2012b) and others at both 3000 m (Bouissou et al 1988) and 4300 m (Maher et al 1975), although it is in contrast with others that have shown an increase with rapid ascent to higher altitudes at 4760 m (Sutton et al 1977) and 6000 m (Okazaki et al 1984). We found no rise in cortisol with exercise in NN, and while some report a rise in cortisol with exercise at SL (Bouissou et al 1988; Wahl et al 2014), this is not a universal finding (Hough et al 2011; Ros et al 2011). We did find cortisol increased significantly immediately following exercise under all hypoxic conditions.…”

PurposeTo investigate whether there is a differential response at rest and following exercise to conditions of genuine high altitude (GHA), normobaric hypoxia (NH), hypobaric hypoxia (HH), and normobaric normoxia (NN).MethodMarkers of sympathoadrenal and adrenocortical function [plasma normetanephrine (PNORMET), metanephrine (PMET), cortisol], myocardial injury [highly sensitive cardiac troponin T (hscTnT)], and function [N-terminal brain natriuretic peptide (NT-proBNP)] were evaluated at rest and with exercise under NN, at 3375 m in the Alps (GHA) and at equivalent simulated altitude under NH and HH. Participants cycled for 2 h [15-min warm-up, 105 min at 55% Wmax (maximal workload)] with venous blood samples taken prior (T0), immediately following (T120) and 2-h post-exercise (T240).ResultsExercise in the three hypoxic environments produced a similar pattern of response with the only difference between environments being in relation to PNORMET. Exercise in NN only induced a rise in PNORMET and PMET.ConclusionBiochemical markers that reflect sympathoadrenal, adrenocortical, and myocardial responses to physiological stress demonstrate significant differences in the response to exercise under conditions of normoxia versus hypoxia, while NH and HH appear to induce broadly similar responses to GHA and may, therefore, be reasonable surrogates.

A well-balanced metabolism means a lower risk for metabolism-related neuropsychiatric disorders. Leptin is a secretory adipokine involved in the central control of appetite that appears to play a role in the etiology of feeding-related disorders. Additionally, the influence of exercise on feeding behaviors potentially modulates the circulation of metabolites that signal through the central nervous system. In this systematic review, we collected the recent clinical evidence on the effect of exercise on leptin concentrations in health individuals published from 2000 to 20 September 2022, according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA 2020 statement). Six hundred and thirty-eight papers were retrieved and forty-eight papers were included in the qualitative synthesis. Data supports that exercise positively influences appetite via enhancing peripheral and central leptin signaling (reuptake), especially during weight loss. Exercise modulation of leptin signaling through leptin receptors helps to stabilize increases in food intake during periods of negative energy balance, prior to a decrease in the body fat tissue content. At a high intensity, exercise appears to counteract leptin resistance.

“…The indoor cycling class was continuously performed [ 9 , 19 , 27 ] and lasted about 40 minutes, divided as follows: warm-up of 5 minutes with an intensity between 2 and 4 of the OMNI scale of perceived exertion for cycling [ 26 ], continuous training of 30 minutes with an intensity between 5 and 7 (OMNI), and cooldown of 5 minutes with intensity between 0 and 2 (OMNI).…”

Objectives. To investigate the effects of distinct concurrent training (CT) protocols on zinc and cortisol concentrations and test the correlation between these blood variables. Methods. Samples of serum zinc and cortisol were assessed from 10 male subjects (27.1 ± 4.8 years old; BMI 25.38 ± 0.09) before and immediately after each study session: control (CS = no exercises), concurrent training 1 (CT1 = indoor cycling + strength training), and concurrent training 2 (CT2 = strength training + indoor cycle) with five days of interval between each. Results. There were no significant changes in zinc concentrations after the CS (Δ% = 8.45; p = 0.07), CT1 (Δ% = 4.77; p = 0.49), and CT2 (Δ% = −2.90; p = 0.12) sessions. Cortisol levels showed significant decrease after CS (Δ% = −6.02; p = 0.00), CT1 (Δ% = −26.32; p = 0.02), and CT2 (Δ% = −33.57; p = 0.05) sessions. There was a significant correlation between the variables only at CS (zinc post versus cortisol pre: r = 0.82 and cortisol post: r = 0.82). Conclusions. CT decreases cortisol concentrations regardless of the sequence performed. No changes were found in zinc concentrations after the study sessions. The reduction in serum cortisol concentrations appear to occur by a mechanism independent of the zinc status.
