Introduction: Physical training can improve several health variables in patients with type 2 diabetes mellitus (T2DM). A growing body of studies also finds a positive influence of dietary supplement (DS) intake. The aim of this review is to shed light on the possible effects of training interventions combined with DS intake in T2DM patients. Metho...

High-intensity functional training (HIFT) integrates different modes of exercise into training sessions performed at a relatively high intensity. Although HIFT is becoming more popular in youth strength and conditioning programs, research comparing the effects of HIFT with traditional forms of training, such as strength training (ST) or endurance t...

Background: Hormones like testosterone play a crucial role in performance enhancement and muscle growth. Therefore, various attempts to increase testosterone release and testosterone concentration have been made, especially in the context of resistance training. Among practitioners, sexual activity (coitus and masturbation) a few hours before train...

The number of people suffering from being overweight or obese has risen steadily in recent years. Consequently, new forms of nutrition and diets were developed as potential solutions. In the last years, the time-restricted feeding and continuous energy restriction via macronutrient-based diets were increasingly popular. Both diets were exclusively...

Cannabidiol supplements (CBD) are increasingly consumed by athletes to improve regeneration. However, the evidence for the pro-regenerative effects of CBD in sports is quite limited. There-fore, our aim was to investigate the effects of a single CBD supplementation in a six-arm place-bo-controlled crossover study after resistance training on perfor...

Ecdysterone is a phytosteroid widely discussed for its various pharmacological, growth-promoting, and anabolic effects, mediated by the activation of estrogen receptor beta (ERbeta). Performance-enhancement in sports was demonstrated recently, and ecdysterone was consequently included in the Monitoring Program, to detect potential patterns of misus...

The aim of this study was to investigate the effects of an 8‑week powerlifting-type bench press (BP) resistance training (RT) program, either without (RAW) or with using a supportive elastic bench press device (EBD) on one-repetition maximum (1-RM), body weight (BW), mid-upper arm and chest circumference, as well as visual analogue pain scale (VAS)...

Nach intensivem Krafttraining spielt die Regenerationsfähigkeit eine entscheidende Rolle, um schnellstmöglich wieder maximale Leistung zu erbringen. Unterschiedliche Behandlungsmethoden sowie Wärme-und Kältetherapie sind in den letzten Jahren im Fokus der Sportler geblieben. Seit dem Ende des 20. Jahrhunderts erfreut sich die Infrarotbehandlung wac...

The breakdown of skeletal muscles increases with age and is further accelerated in today’s society due to lower physical activity. The skeletal muscles are primarily responsible for the transmission of force and thus for our everyday movement. With the reduction of muscle mass, the execution of everyday movement is continuously hampered and the qua...

Zusammenfassung CrossFit® (CF) bedient sich ständig variierender funktioneller Bewegungen in sogenannten „Workouts of the Day“ (WOD), die oft unter Zeitdruck ausgeführt werden. CF wird daher oft kritisiert, da es möglicherweise ein hohes Verletzungsrisiko birgt. Es existieren Studien zu Verletzungshäufigkeiten beim CF aus den USA, den Niederlanden...

Global consumption of dietary supplements has been rising steadily for more than a decade. Especially in competitive sports, dietary supplements are consumed by more than 75% of athletes. However, only a fraction part of the athletes take advantage of appropriate expert care. Apart from the lack of care for athletes, the data available on scientifi...

Background Alpha lipoic acid (ALA) has been demonstrated to have anti-inflammatory activity and was tested as a drug for the treatment of various diseases. ALA is also frequently used as a nutrition supplement, in healthy individuals or in competitive athletes. However, information from intervention studies investigating physiological effects of an...

The purpose of this study was to investigate whether a six-week, twice weekly resistance training (4 sets at 30% 1-RM until failure) with practical blood flow restriction (BFR) using 7cm wide cuffs with a twist lock placed below the patella is superior to training without BFR (NoBFR) concerning muscle mass and strength gains in calf muscles. A two-...

Objectives Nutrition is a key element in post-exercise regeneration. Various studies suggest that ingestion of combined carbohydrates and proteins after exercise result in a decrease of inflammatory processes and consequently in an increase of regeneration and physical performance. Recent studies compared the pro-regenerative effects of protein/car...

The medical qualities of cannabidiol (CBD) have been known for a long time. Especially in recent times increasingly more research is being conducted on this subject. Nevertheless, the direct effects of CBD on regeneration after physical activity are still unclear. Even though the anti-inflammatory effect of CBD is undisputed in medicine, the extent...

Recent studies suggest that the anabolic effect of ecdysterone, a naturally occurring steroid hormone claimed to enhance physical performance, is mediated by estrogen receptor (ER) binding. In comparison with the prohibited anabolic agents (e.g., metandienone and others), ecdysterone revealed to be even more effective in a recent study performed in...

Purpose Weight lifting training has gained much popularity in recent years and is frequently used in non-professional and professional settings. However, little is known about the acute effects of a highly intensive weight lifting exercise (clean and jerk) on the hemodynamic reaction. Methods 18 non-professional experienced weight lifters were rec...

Physical performance and regeneration after exercise is enhanced by the ingestion of proteins and carbohydrates. These nutrients are generally consumed by athletes via whey protein and glucose-based shakes. In this study, effects of protein and carbohydrate on skeletal muscle regeneration, given either by shake or by a meal, were compared. 35 subje...

Anabolic steroids have a long history of abuse in amateur and professional athletics. However, their interaction with training and the resulting effects on body composition and tissue adaptation, relying on a concert of factors and pathways, remain under investigation. This study aims at investigating the changes of body composition and the express...

Consumption of pre-workout supplements (PWS) has increased substan- tially in recent years. However, dosages of ingredients vary between man- ufacturers. Therefore, the aim of this study was to analyze ingredients from various products and to survey past and present (4 weeks) consumption behavior. Analysis of ingredients was performed in 30 produ...
