Rapid Weight Loss Across Combat Sports And The Relationships Between Methods And Magnitude, Oliver R. Barley, Craig A. Harms

Research outputs 2022 to 2026

This study examined rapid weight loss (RWL) habits across combat sports (CS) and how common usage of different methods was related to the magnitude of RWL. Competitors (N = 256) from CS including boxing, Brazilian jiu-jitsu, muay thai/kickboxing (MT/KB), wrestling, mixed martial arts (MMA), judo, taekwondo, and karate participated in the study. Athletes completed an online survey which included questions on their regular weight loss habits, including magnitudes of weight loss over different time periods and types of methods utilised. Athletes typically started losing weight in their early 20s and engaged in RWL on average three times a year. Magnitudes …

Research outputs 2022 to 2026

Inadequacies in the conduct and quality of research are well established across many research domains, including sport science and medicine. Metaresearch—the practice of performing research on research—is presented as a practical vehicle for improving research quality through evaluating the research processes. This article introduces the concept of metaresearch to sport as a new sub-field of sport science. The broad types of metaresearch are introduced, with a mapping of current sports metaresearch activity across these areas. Interdisciplinary centres aimed at improving scientific quality across other fields are also introduced to sport, and specific considerations for beginning metaresearch are provided for sport. …

Why We Must Stop Assuming And Estimating Menstrual Cycle Phases In Laboratory And Field-Based Sport Related Research, Kirsty Jayne Elliott-Sale, Marco Altini, Patricia Doyle-Baker, Eva Ferrer, Tessa Rose Flood, Rachel Harris, Franco Milko Impellizzeri, Xanne Janse De Jonge, Katrine Okholm Kryger, Gary Lewin, Constance M. Lebrun, Alan Mccall, Sophia Nimphius, Stuart M. Phillips, Paul A. Swinton, Madison Taylor, Evert Verhagen, Richard James Burden

Research outputs 2022 to 2026

The increased growth, popularity, and media interest in women’s sport has led to calls for greater prioritisation of female-specific research and innovation. In response, science and medicine researchers have increased the volume of sport-related studies investigating female-specific matters, such as the menstrual cycle. Whilst the accelerated rate of published studies with female participants is welcome, the emerging trend of using assumed or estimated menstrual cycle phases to characterise ovarian hormone profiles is a significant concern. Replacing direct measurements of key characteristics of the menstrual cycle (e.g. the surge in luteinising hormone prior to ovulation via urine detection and sufficient luteal …

Effect Of 6-Week Single Leg Countermovement Jump Training On Force Time Metrics In Elite Female Youth Footballers, Jack T. Fahey, Paul Comfort, Paul Jones, Nicholas, J. Ripley

Research outputs 2022 to 2026

Female football participation has grown exponentially. Unfortunately, females exhibit greater injury risk than male athletes, and experience increased mechanical stress during adolescence. Force plates provide accurate and reliable force-time characteristics enabling profiling of injury risk and benchmarking using a variety of jump and isometric tasks. The purpose of this study was to determine whether test-retest reliability and force-time characteristics of SLCMJ, bilateral countermovement jump (CMJ), countermovement rebound jump (CMJ-R) and isometric mid-thigh pull (IMTP) change with six weeks of SLCMJ training. Twenty-eight elite youth female footballers (13.7 ± 1.1 years, 53.27 ± 8.82 kg, 162.20 ± 5.37 cm) completed six …

Research outputs 2022 to 2026

Post-exercise recovery strategies influence the body’s ability to restore physiological homeostasis, replenish energy stores, repair muscle damage, and promote desired adaptations, which improve exercise performance. This narrative review examines the impact of nutritional strategies commonly used for enhancing recovery and subsequent exercise performance, particularly when athletes face short recovery periods. Carbohydrate ingestion is essential for glycogen replenishment, especially within the initial hours post-exercise, with its impact dependent on the types, timing, and amount. Protein is essential for accelerating muscle recovery and achieving a positive nitrogen balance, depending on the type and dosage. The co-ingestion of carbohydrates with proteins or fats …

This type of research is quasi experimental with a pre-post test design in a population of 90 low back pain patients who seek treatment at the Physiotherapy clinic. By using …

Effectiveness Of Using Soft Exosuit In Stroke Case To Improve Walking Speed And Endurance, Aditya Denny Pratama, Rakha Shidqi Widyadhana

Jurnal Fisioterapi Terapan Indonesia

Stroke is a clinically defined syndrome of acute, focal nerve discharge caused by vascular injury (infarction, hemorrhage) of the central nervous system. Punches can cause damage to the brain and affect a person's ability to walk, balance and coordinate movements. Impaired gait is common in stroke cases, often resulting in poor recovery of mobility and inability to carry out daily activities without assistance. One of the interventions that can be used is a soft exosuit. This method can help overcome walking problems in stroke patients where soft exosuits are used to increase walking speed and walking endurance. The purpose of …

Programmatic Accreditation: Implementation Strategies For College Kinesiology Program Directors, Kworweinski Lafontant

Topics in Exercise Science and Kinesiology

Programmatic accreditation within Kinesiology sub-disciplines, such as physical therapy and sports medicine, have typically been required at the graduate level. Within the coming decade, major certifications for exercise physiology (ACSM-EP) and strength & conditioning (CSCS) will institute programmatic accreditation requirements at the undergraduate level. This article takes a narrative review approach at examining ways that programmatic accreditation at the undergraduate level may impact incoming undergraduate students, such as necessitating earlier specialization and limiting the ability for late-stage career changes. To mitigate these impacts, college kinesiology program directors may benefit from considering the perspectives of students as they work to meet …

The Relationship Between International Tennis Association Rankings And Total Athleticism Score In Collegiate Athletes, Ryne Yamashiro, Paulette Yamada, Trevor Short

Topics in Exercise Science and Kinesiology

Training tennis athletes for peak athletic performance may translate to enhanced on-court performance, resulting in higher rankings. However, the specific trainable tennis attributes that account for the variance in International Tennis Association (ITA) remain elusive. ITA Rankings are calculated based on how a collegiate tennis athlete performs whereby their rankings will change based on wins or losses and scores against their opponents ITA Ranking. A lower ITA Ranking (closer to 1) indicates a higher ranked tennis player. Holistic athletic profiling can be performed by assessing multiple key performance indicators, with the total athleticism score (TAS) being utilized to …

Analysis Of The Longitudinal Effect Of Home Advantage In The Brazilian Football Championship – Série A, Werlayne Leite, Marcelo C. Zanetti

Baltic Journal of Health and Physical Activity

Athletes and teams typically obtain an advantage when competing at home, a phenomenon known as home advantage (HA). This study investigates the longitudinal effect of HA in the Brazilian Football Championship (Série A) over 21 seasons, analyzing 8,405 matches from 2003 to 2023. The results showed that the average HA was 35.1 ± 7.7%, while the competitive balance (CB) was 0.838 ± 0.145. A negative, non-significant correlation (r = -0.321, p = 0.157) was found between HA and CB, with CB explaining 10.3% of HA variation in the Brazilian league. HA de-creased over time, likely due to improved logistics, …
