OBJECTIVETo examine the effects of three seasonal training programs, largely different in strength volume, on androgen levels and performance parameters in soccer players.DESIGNSixty-seven soccer players, members of three different professional teams, participated in the study. Strength intensity of the training programs were assessed as high (for Team-A, n = 23), moderate (for Team-B, n = 22), and low (for Team-C, n = 22). Blood samples were analyzed for total-testosterone, free-testosterone… 
Testosterone Concentration and Lower Limb Power Over an Entire Competitive Season in Elite Young Soccer Players
TLDR
The findings of this study suggest that T changes and power changes are not related.
Strength training in soccer with a specific focus on highly trained players
TLDR
The analysis suggests that neuromuscular training improves both physiological and physical measures associated with the high-level performance of soccer players, as well as the effects of concurrent strength and endurance training on the physical capacity of players.
The complex and bidirectional interaction between sex hormones and exercise performance in team sports with emphasis on soccer
TLDR
A review of the currently available knowledge regarding the complex relationship between athletic training and competition and sex steroid hormone adaptation to the demands of the exercise effort and the reciprocal effects of exercise on the endogenous sex hormones.
Hematology, Hormones, Inflammation, and Muscle Damage in Elite and Professional Soccer Players: A Systematic Review with Implications for Exercise
TLDR
It is suggested that long-term soccer training induces increases/decreases in hematological, hormonal, inflammatory, and muscle damage markers and physical performance in male elite and professional soccer players.
Effects of Circuit Resistance Training with Different Parts of Saffron Supplementation on Testosterone and Cortisol Hormones
TLDR
Investigation of the effects of circuit resistance training and saffron supplementation on plasma testosterone and cortisol in young college men found this improvement was increased when this training combined with saffrons supplements.
Monitoring Blood Biomarkers and Training Load Throughout a Collegiate Soccer Season.
TLDR
Routine biomarker monitoring revealed subclinical and clinical changes, suggesting soccer-specific reference ranges, and biomarker monitoring may augment positive adaptation and reduce injuries from stressors incurred during soccer.
Exercise associated hormonal signals as powerful determinants of an effective fat mass loss.
TLDR
It is proposed that reducing intra-abdominal fat mass and increasing cardiorespiratory fitness through improving nutritional quality, reducing sedentary behavior, and increase the participation in physical activity/exercise, might be associated with clinical benefits, sometimes even in the absence of weight loss.
The Training of Short Distance Sprint Performance in Football Code Athletes: A Systematic Review and Meta-Analysis
TLDR
This review provides the largest systematic review and meta-analysis of short-sprint performance development methods and the only one to assess football code athletes exclusively.
Sarcopenic obesity
TLDR
A consensus on the definition of sarcopenic obesity is considered essential to facilitate the performance of mechanistic studies and clinical trials aimed at deepening knowledge, thus enabling improved management of affected individuals in the near future.

CHANGES IN EXERCISE PERFORMANCE AND HORMONAL CONCENTRATIONS OVER A BIG TEN SOCCER SEASON IN STARTERS AND NONSTARTERS
TLDR
Data indicate that players entering the season with low circulating concentrations of T and elevated levels of C can experience reductions in performance during a season, with performance decrements exacerbated in starters over nonstarters.
Strength training effects on physical performance and serum hormones in young soccer players
TLDR
The inverse correlations observed between changes in CMJ40 and changes in the testosterone:cortisol ratio suggest that a transient drop in this ratio below 45% cannot always be interpreted as a sign of overstrain or neuroendocrine dysfunction.
Effects of In-Season Strength Maintenance Training Frequency in Professional Soccer Players
TLDR
Performing 1 weekly strength maintenance session during the first 12 weeks of the in-season allowed professional soccer players to maintain the improved strength, sprint, and jump performance achieved during a preceding 10-week preparatory period.
MUSCLE STRENGTH, SERUM BASAL LEVELS OF TESTOSTERONE AND UREA IN SOCCER ATHLETES SUBMITTED TO NON-LINEAR PERIODIZATION PROGRAM
TLDR
The non-linear training in soccer players was more effective than the non-periodized training in promoting increase in serum testosterone levels and reduction in urea levels.
Seasonal Aerobic Performance Variations in Elite Soccer Players
TLDR
It is suggested that heart rate, lactate, &OV0312;o2, and v-4 mmol·L−1 are useful and practical predictors that help monitor aerobic performance changes during a soccer season.
Hormonal responses after various resistance exercise protocols.
TLDR
The number of sets functions up to a point as a stimulus for increased hormonal concentrations in order to optimize adaptations with MH and SE protocols, and has no effect on a MS protocol.
EFFECTS OF SPRINT AND PLYOMETRIC TRAINING ON MUSCLE FUNCTION AND ATHLETIC PERFORMANCE
TLDR
It is concluded that short-term sprint training produces similar or even greater training effects in muscle function and athletic performance than does conventional plyometric training.
Effects of football on the pituitary-testicular axis (PTA): differences between professional and non-professional soccer players.
TLDR
Basal LH values in the rest period were significantly higher in PSP than in control men, whereas LH RMR and sperm motility were significantly lower in the former group, and no significant differences in basal hormone concentration and in the RMRs to GnRH-TRH were observed between PSP and NPSP.
Effects of heavy-resistance training on hormonal response patterns in younger vs. older men.
TLDR
The data indicate that older men do respond with an enhanced hormonal profile in the early phase of a resistance training program, but the response is different from that of younger men.
Muscle hypertrophy, hormonal adaptations and strength development during strength training in strength-trained and untrained men
TLDR
The correlations between T and the changes in isometric strength and in muscle CSA suggest that both serum basal testosterone concentrations and training-induced changes in acute testosterone responses may be important factors for strength development and muscle hypertrophy.
