Filter by:Sport specialization requires an understanding of morphological variability to optimize performance. However, the current literature lacks a detailed analysis of the anthropometric profile of track and field athletes, especially in Latin America. Additionally, the five-way fractionation method of body mass has been under-documented. These gaps highlight the need for more research to maximize the potential of athletes, particularly in emerging countries like Mexico. This study aims to determine the anthropometric characteristics of elite and Olympic Mexican track and field athletes. A descriptive cross-sectional study will be conducted. Forty-three anthropometric variables will be assessed to characterize the athlete´s physical composition using the standards of the International Society for the Advancement of Kinanthropometry (ISAK). Those variables will be used to describe the anthropometric profile (Heath and Carter somatotype, body composition through five-way fractionation method, muscle bone index, muscular adipose index, sum of skinfold thicknesses, and proportionality through Ross & Wilson Phantom strategy. Correspondences of those variables will also be established among different tests and specialties: sprint, middle-distance, long-distance, endurance, combined events, jumps, and throws. This study aims to provide the opportunity to generate reliable references for high-performance Mexican athletes.
Given conflicting studies regarding the effect of land-based and water-based training on the jump performance of volleyball and basketball players, a randomized controlled trial is conducted. This study hypothesizes that combined land- and water-based core and lower strength training significantly increase jump performance of volleyball and basketball players in comparison to either land- and/or water-based training alone.
Despite a rise in the number of women participating in competitive sports, there remains a gender gap within sport and exercise science literature. Studying females involves potential "noise" through the change in hormone concentrations during the different phases of the female menstrual cycle (MC) which can potentially affect physiological parameters, thereby making study design and interpretation of findings difficult. Longitudinal data on the acute and chronic combined effects of training load and MC phases on circulating female hormones in elite and non-elite female athletes is lacking. The investigators aim to characterize and track the potential effects of training load and MC phases on performance, anthropometric measures, sport emotions, intestinal microbiome, serum metabolites and injury prevalence in elite and non-elite female athletes. 200 competitive premenopausal female athletes will be recruited. In a longitudinal observational design, each participant will be followed for 1 year, and tested at three time points. At each point, data will be collected on two occasions reflecting distinct phases of the MC. Finding the possible relationship between the MC phases, training load and performance or specific bio-markers for training load are of utmost importance and can assist professionals to identify periods of high load and over-training, thus preventing injuries and training adjustment.
This study aims to investigate the musculotendinous adaptations in the Achilles tendon and the muscles composing the triceps surae induced by triathlon training and competitions in high-performance and low-performance athletes. Twenty high-performance triathletes, twenty low-performance triathletes, and twenty physically active and healthy individuals of both genders will be recruited to constitute the research groups. Ultrasonography will be employed as the assessment method for the structures of the Achilles tendon and the muscular architecture of the triceps surae. The quality and portability of ultrasonography, coupled with its real-time information capabilities, make it the appropriate choice for this evaluation. The VISA-A scale (Victorian Institute of Sport Achilles Assessment) will be used to measure pain and function of the Achilles tendon. The reliability of ultrasonography measures will be obtained by evaluating images of individuals using the intraclass correlation coefficient, allowing for the analysis of result reproducibility. Data analysis will involve comparisons among the high-performance, low-performance, and physically active groups, aiming to identify differences in musculotendinous adaptations related to performance and injury predisposition. Structural changes occurring in these structures and their potential association with sports performance and/or injury predisposition will be explored. Overall, this study utilizes a comparative cross-sectional research design, where different groups are assessed regarding musculotendinous adaptations in the Achilles tendon and triceps surae through ultrasound-derived measures. The use of the VISA-A scale and the assessment of measure reliability will provide additional data on pain, function, and result reproducibility.
"Investigating the Development, Validity, and Reliability of the Avoidance of Sports Activities Photo Scale" is crucial in determining the specific functional status of the shoulder joint, especially for overhead athletes experiencing shoulder pain, to identify which sporting activities restrict them the most and to fill the gap in the literature. Additionally, visually indicating activities through photographs will provide visual feedback, making it easier to assess functional status. Our study aims to develop a specific functional survey for the shoulder joint in overhead athletes, examine the validity and reliability of this scale, and contribute to the literature.
Creatine is an effective, inexpensive, and safe dietary supplement, which has been largely used in sports and clinical populations. However, creatine is much less studied in female athletes, with long-term data being particularly scant. This study aims to expand our knowledge on the effects of creatine supplementation in young (Under-20) and elite female football players. This study will comprise two experiments. The first one will be a randomized, controlled trial in which young athletes will be assigned into either creatine or placebo (n = 20). Before and 7 days after supplementation or placebo (4 x 5 g/d of Creapure or dextrose at same dose), athletes will perform a battery of performance tests. Blood and urinary biochemical parameters for assessing the safety of supplementation will be analyzed (creatinine, albuminuria, urea, sodium, potassium, liver enzymes, creatine kinase, hematology). Food intake will be assessed by means of 3-d 24-h dietary recalls. The second experiment will have a quasi-experimental design (i.e., pre-to-post), in which both young and elite football players (n = 70) will be supplemented with creatine (4 x 5 g/d for 7 days and then 5 days during the follow-up) and will be assessed for safety using the above-mentioned markers during the regular football season (~12 months). Assessments will be carried out at baseline, in the mid-season and after the season.
The hamstring muscle is one of the key elements in rehabilitation programs and sports activities that enable the restoration of optimal muscle length. Decreased flexibility in the hamstring muscle may disrupt the biomechanics of the waist and pelvis, leading to low back pain or musculoskeletal disorders. This study aims to investigate the acute effects of foam rolling and proprioceptive neuromuscular facilitation stretching during warm-up on muscle flexibility, strength, and pain threshold in amateur athletes. According to our research, there is no study in this field in the literature. H1: There is a difference between the acute effects of foam rolling exercise and PNF stretching exercise on muscle flexibility during warm-up in amateur athletes. H2: There is a difference between the effects of foam rolling and PNF stretching exercises used as warm-up exercises on muscle strength. H3: Foam rolling and PNF stretching exercises applied to the Hamstring muscle as a warm-up exercise make a difference in the pain threshold of the lumbar region and Hamstring muscle.
