“…Despite the frequency which T, C and T:C are used in the literature as markers of fatigue and anabolic-catabolic balance 27,28,47 , this study did not find consistent changes in T, C, or T:C as workloads changed throughout the season, as reported by sRPE. There were also no relationships found between T, C or T:C and CRP, CK or cf-DNA.…”

Objectives: This study investigated chronic changes in cell free DNA (cf-DNA) throughout a collegiate soccer season. The relationship between cf-DNA, C-reactive protein (CRP), creatine kinase (CK), testosterone (T), cortisol (C), testosterone-cortisol ratio (T:C), body mass and body composition were also examined. Design: Longitudinal study design with repeated measures and group comparisons. Methods: Twenty three NCAA Division I male soccer players were divided into two groups. Starters were placed in Group 1 (G1) and non-starters were placed in Group 2 (G2). cf-DNA, CRP, CK, T, C, T:C, body mass and body composition were taken three times, corresponding to pre-season, approximately mid-season and immediately after the concluding the season. Results: In G1, cf-DNA, CRP, CK, cf-DNA %∆, CRP %∆ and, CK %∆ were all statistically higher at T2 and T3 than T1. In G2, CRP %∆ was statistically higher at T2 than T1. In G2, cf-DNA %∆, CRP %∆ and CK %∆ were higher at T2 and T3 than T1. Conclusions: This suggests that cf-DNA may be a useful marker that can reflect accumulated soccer training and competitive stressors.(Journal of Trainology 2015;4:25-31)

“…Importantly, enhanced resting testosterone/cortisol (T/C) ratio has been associated with increased strength (5). Therefore, monitoring T and C can provide insight into an athlete's recovery/readiness (6), and can be a tool to program daily volume/ intensity of training (7).…”

ResumenIntroducción: la distribución específica de macronutrientes y el entrenamiento pueden alterar el comportamiento agudo y crónico de las hormonas y, posteriormente, el rendimiento deportivo. Objetivo: el objetivo principal del estudio fue examinar la relación entre la ingesta dietética y la respuesta anabólica/catabólica hormonal de jugadoras de élite de voleibol durante una temporada de 29 semanas. Métodos: se evaluó en 22 jugadoras de élite (26,4 ± 5,6 años, 178 ± 9 cm, 67,1 ± 7,5 kg) la ingesta dietética (mediante un registro de siete días y un cuestionario de frecuencia de consumo de alimentos), la concentración de hormona anabólica/catabólica en sangre, el rendimiento físico y la composición corporal en cuatro puntos durante la temporada: a) T1: pre-pretemporada; b) T2: once semanas después de T1; c) T3: diez semanas después de T2; y d) T4: ocho semanas después de T3. Las hormonas evaluadas fueron: testosterona total (TT), testosterona libre (FT), hormona adrenocorticotropa (ACTH) y cortisol (C); se calcularon distintos ratios hormonales. Resultados: se observaron correlaciones positivas entre la ratio carbohidratos/proteínas con ΔFT (r = 0,955; p < 0,001), ΔTT/C (r = 0,638; p = 0,047) y ΔFT/C (r = 0,909; p < 0,001). Se encontraron correlaciones significativas y negativas entre la ingesta proteica con ΔTT (r = -0,670; p = 0,034) y FT (r = -0,743; p < 0,001), la ingesta de carbohidratos y ΔACTH (r = -0,658; p = 0,006). No se observó ningún tipo de correlación con el Δcortisol. Por otro lado, no hubo cambios (p > 0,05) en la masa corporal ni en el índice de masa corporal en ningún momento, mientras que el sumatorio de seis pliegues mejoró (p < 0,05) de T1 (86,5 ± 6,9 mm) a T4 (75,2 ± 5,6 mm), así como la masa muscular (T1: 28,9 ± 0,7 kg frente a T4: 30,1 ± 0,8 kg). El salto vertical, el salto de remate y la velocidad mejoraron (p < 0,05) de T1 a T4. Conclusión: en conclusión, una alta ratio de carbohidratos/proteínas se asoció con cambios positivos en el anabolismo, mientras que una ingesta alta de proteína y baja de CHO se asoció con una respuesta anabólica atenuada. AbstractIntroduction: Specific macronutrient distribution and training can alter acute and chronic hormone behavior and, subsequently, sport performance. Objective: The main aim was to examine relationships between dietary intake and anabolic/catabolic hormone response in elite female volleyball players during a 29-week season. Methods: Twenty-two elite female volleyballers (26.4 ± 5.6 years; 178 ± 9 cm; 67.1 ± 7.5 kg) had dietary intake (seven-day dietary recall and food frequency questionnaire), blood concentration of anabolic/catabolic hormones concentration, physical performance, and body composition assessed at four time points: a) T1: baseline/pre-testing; b) T2: eleven weeks after T1; c) T3: ten weeks after T2; and d) T4: eight weeks after T3. Hormones evaluated were: total testosterone (TT), free testosterone (FT) adrenocorticotropic hormone (ACTH), and cortisol (C), along with hormone ratios. Results: Positive correlations were obs...

“…Despite the informative content, frequent interventions have met limited practical application in competitive sport because of possible alteration in the regular course of the training cycle. Standardised repeated single interventions as longitudinal measures of hormonal, immunological and biochemical variables have been described in different sports, including team-game sports, as an expression of the impact of training [3,13,15,16,[18][19][20]23]. Analysis of longitudinal measurements can be carried out in comparison with an accepted reference interval but such an approach is not always productive in the case of athletes because of biological, procedural and environmental influences [12].…”

Close complex monitoring during the entire training period is essential for professional athletes to assess the effect of the training programme and to determine the quality of recovery. Follow-up of biochemical and hormonal variables throughout the season can help realize the abovementioned goals.Objectives: To determine baseline blood creatine kinase (CK) and cortisol (C) levels in professional basketball players before the beginning of regular training and to follow up the subsequent levels of blood C and CK over an entire season with analysis of dynamic changes in relation to individual coefficients of variation.Methods: Six professional basketball players were monitored from the first pre-season day to the end of a regular season. Blood samples were collected at six time points: before the pre-season, after the pre-season and four times during the in-season to determine blood C and CK concentrations.Results: Individual trends of the investigated variables were established and analysed with respect to the calculated intra-and inter-individual coefficients of variation for C and CK. Dynamic changes in C and CK levels coincided with changes in the content of the training process.Conclusion: In summary, the findings in the present study suggest that long-term intensive exercise in basketball has a significant influence on the blood cortisol profile. Muscle damage was associated with bodily collisions between the players but not with stress response in the current study.
