Filter by:The aim of this randomized, double-blind, placebo-controlled crossover trial is to evaluate the effect of hydrogen-rich water consumption on performance, recovery, psychological and biochemical outcomes in elite Czech fin-swimmers.
The menstrual cycle implies a basic difference in the biology of women and men but the effect of the hormonal variation on training protocols and physical performance is still not fully understood. Despite no existing evidence, the advice to periodize exercise according to the menstrual cycle has been widely spread among elite athletes, coaches, and sports federations. The advice is based on underpowered studies with considerable methodological weaknesses regarding determination of cycle phase, inclusion of athletes and lack of adequate control groups. The purpose of this randomized, controlled study is to evaluate the effect of exercise periodization on aerobic fitness during different phases of the menstrual cycle. Further, the effect will be related to premenstrual symptoms, body composition and skeletal muscle morphology, sex hormone receptors, metabolic enzymes, and markers of muscle protein synthesis. This study will be well controlled and follow methodology recommendations for menstrual cycle research in sports and exercise. Female athletes of fertile age will be randomized to different training regimens during three menstrual cycles (12 weeks): Group A: Training three times a week throughout the menstrual cycle. Group B: Follicular phase-based training five times a week during the follicular phase and thereafter once a week during the luteal phase. Group C: Luteal phase-based training five times a week during the luteal phase and once a week in the follicular phase. The exercise will consist of high intensity intermittent spinning classes. Assessment of aerobic fitness and power will be performed at baseline, and again after three completed menstrual cycles. On the same day, body composition will be examined by DXA and blood samples will be collected for analysis of hormones and binding proteins. To confirm menstrual cycle phase, blood samples will be collected for hormone determination, and urinary stick will be used for detection of ovulation. Subjective ratings of menstrual cycle related symptoms will be performed every day. In a subgroup of women, muscle biopsies will be collected from m vastus lateralis at baseline and at the end of the study. This study will contribute to improved knowledge about exercise periodization in relation to the menstrual cycle. Well-grounded data is crucial to give evidence-based recommendations to female athletes when planning their training protocol to optimize training results and performance.
The overall aim of this project is to compare protein supplementation on performance, recovery, and body composition changes in adolescent soccer players between the whey protein and the control group in response to the 10-12-week intervention.
The feeding strategies during recovery are essential to optimize a subsequent performance. Carbohydrate is a major fuel source during exercise as it has been shown to maintain high rates of carbohydrate oxidation. Protein intake in combination with carbohydrate have been shown to increase Amino acid bioavailability and may alter physiologic responses during exercise, which may be relevant to endurance performance. The goal of this study is to assess the effect of a new developed vegan product on athletes recovery and subsequent performance.
To date, only one study has evaluated the effect of caffeine supplementation on athletic performance in ice hockey players finding a lack of ergogenic effect. This lack of effect is surprising as caffeine has been suggested to be an effective and safe nutritional supplement to improve physical performance in both trained and untrained individuals. Therefore, the aim of the present study is to evaluate the effect of acute caffeine ingestion (3mg/kg body mass). Thirteen elite adult ice-hockey male players will perform specific ice hockey performance tests in two separate days. On both occasions players will ingest 330 ml of water with lemon powertabs isostar® (86 kcal / 19g of carbohydrates) tablets, which will include in one of these days 3 mg/kg body mass of anhydrous caffeine. Players will perform a 35-m sprint, an agility test (Weave agility - slalom with puck), and a reaction test.
This study was planned to explain the relationship between heart rate variability and their sportive performance in basketball players.
The aim of the study is to evaluate the effect of an eight-week specific Core Stability Training (CST) on young rhythmic gymnasts. The literature suggests CST may help improve sport performance, however, more studies implementing functional CST and accurate methodology are needed to validate this statement. Little is known about Core Stability (CS) and Rhythmic Gymnastics (RG). The study intends to find out whether CST contributes to the Rhythmic gymnasts core stability, balances and jumps execution enhancement, very important RG performance determinants. It is hypothesized the rhythmic gymnasts will increase their CS, balances and jumps performance once the specific CST is conducted.
Golf is becoming increasingly popular in Germany. However, the biomechanical and motor challenge of golf should not be underestimated. Nevertheless, only very few amateur golfers carry out serious preparation and conditioning as part of a strength/stabilization program. The main argument for this limitation is the aspect of "limited time resources". A solution to this problem could therefore be the time-effective and highly individualizable whole-body electromyostimulation (WB-EMS) technology. The aim of the present study is to evaluate the effectiveness of 16 weeks of WB-EMS application on trunk stability and clubhead speed in male amateur golfers in a (randomized) controlled setting.
26 Tae Kwon Do athletes performed a vigorous exercise program on the isokinetic dynamometer twice in a period of 10 days, each time on a different extremity. In this way two groups of 26 individuals each were created, with the same individuals alternating. In the massage group (MG) a sport massage was applied between the sets while in the control group (NMG) the break was passive.
This study aims to evaluate the potential benefits of Monopolar Capacitive Resistive Radio-frequency (448 kHz) on the sports performance of Paralympic swimmers.
