Filter by: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.
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.
Maximal fat oxidation during exercise (MFO) and the intensity of exercise that elicits MFO (Fatmax) has been recognized as potential determinants of endurance performance. The purpose of this study was to determine the possible interaction between the effects of diurnal variation (morning vs. afternoon) and caffeine ingestion on MFO, Fatmax and VO2 max in endurance-trained men. Specifically, the investigators sought to elucidate whether the stimulant actions of caffeine could reverse the decrements of MFO and Fatmax observed in the morning.
The purpose of this study was to examine the variation in physical and physiological characteristics according to sports age in adolescent and adult male team handball (TH) players. Adolescent (N.=19, aged 18.1±1.4 yr) and adult (N.=23, 28.6±5.7 yr) players were examined for anthropometric characteristics, somatotype and body composition, and performed the physical working capacity test, a force-velocity test, the lateral scapular slide test (LSST), shark skill test, Davies test, squat jump (SJ), countermovement vertical jump without (CMJ).
A ketogenic diet (KD) is a nutritional approach, usually adopted for weight loss, that restricts daily carbohydrates under 30 g/day. KD showed contradictory results on sport performance, whilst no data are available on team sports. The investigators will investigate the influence of a KD on different parameters in soccer players
Many different factors affect running performance, transcranial direct current stimulation (tDCS) is a widely used and available neuromodulation tool and could hypothetically facilitate the supraspinal drive and thereby act upstream of the motor cortex to prolong the muscles work in time to exhaustion trials. While it appears to decrease the rating of perceived exertion (RPE) during cycling, little is known about the effects of tDCS on physiological performance parameters such as maximal oxygen consumption (VO2max), maximal aerobic speed (MAS) and lactate thresholds in runners. The aim of this prospective randomized sham-controlled clinical trial is to investigate the physiological effects of tDCS applied over the motor cortex on perceived exertion and performance-related parameters measured by an incremental treadmill test to exhaustion. This research thus aims at answering the following questions: 1. Is active tDCS applied bilaterally over the motor cortex significantly more efficient than sham tDCS to improve the TTE? 2. Does active tDCS decreases the RPE, as compared to sham? 3. Is there any significant difference between active and sham tDCS on the physiological parameters measured during an incremental test to exhaustion, namely: VO2max, MAS, respiratory exchange ratio, blood lactate levels, maximal heart rate? 4. Does the baseline level of physical fitness influences response to tDCS? The investigators hypothesize that 1) performance as measured by time to exertion will be increased following active and not sham tDCS due to a decreased perceived rate of exertion without significantly altering the other physiological parameters; and 2) performance as measured by incremental treadmill test to exhaustion will be more improved in recreational as compared to trained runners.
Worldwide, soccer has grown increasingly popular among female players. According to the Women´s Football Survey of the Fédération Internationale de Football Association (FIFA), there were more than 30 million registered women soccer players in 2014. Elite female soccer players cover approximately a total distance of 10 km with 1.7 km completed at high-speed (>18 km/h-1), between 1350 and 1650 changes of activity like passing, dribbling, tackling and trapping and 5.1 and 31.2 repeated sprinting and high intensity bouts, respectively. Thus, it seems that those strategies addressed to improve such high-intensity activities should be considered a priority for female soccer players. Different training methods to improve soccer specific variables have been developed such as, high-intensity interval training, resisted sprint training, strength training or plyometric training. Whilst individual training interventions have been shown to produce enhancements in measures of athletic performance for soccer players, there is a paucity of studies looking at the effectiveness of strength and power training specifically on performance measures in female soccer populations. Unilateral strength asymmetry can be a risk factor of musculoskeletal injuries. In recent years, inter-limb asymmetries have been included in battery tests performed by different soccer clubs due to their relation with lower-limb injuries. Few studies have analysed the change of an intervention on inter-limb asymmetry in female soccer players, hence, more studies for this population are warranted. The main aim of this research project is therefore, to evaluate the effect of a physical intervention on the performance and inter-limb asymmetries of female soccer players.
In a constant effort to find ways to make a quicker recovery between demanding workouts and football matches, this study is the first to investigate the benefits of protein supplementation, and compares two types of proteins, an animal-derived (whey) and a plant-derived (soy) protein, after an exercise-induced muscle injury caused by a speed endurance training protocol. Soy protein could be a cheaper and more environment-friendly alternative for athletes involved in high-velocity strength training.
