Systematic Review with Meta-analysis
Int J Sports Med DOI: 10.1055/a-2161-4867This systematic review and meta-analysis aimed to determine whether Olympic
weightlifting (OW) exercises would improve sprint performance when compared to a
control intervention, (no training, standard sport-specific training,
traditional resistance training, or plyometric training). Medline, Web of
Science, SportDiscus, CINAHL, and Biological Science from inception to September
2022 was searched. Two authors independently selected the included studies,
extracted data, and appraised the risk of bias. Certainty of the eviden...

Change of Direction Asymmetry in Youth Elite Tennis Players: A
Longitudinal Study
This study examined the development of change of direction
(COD) asymmetry magnitude in youth elite tennis players. Dominant (overall best
performance) and non-dominant (best performance on the other side) scores and
COD asymmetry magnitude were quantified annually (up to six years) in 323 male
and 235 female players (ages 6 to13 years). Linear mixed effects regression
models examined the development of COD performance and asymmetry magnitude
according to players’ chronological age and sex. Kappa coefficients
examined the consistency for the direction ...

Exertional Stress-induced Pathogenic Luminal Content Translocation – Friend or Foe?
Int J Sports Med DOI: 10.1055/a-2235-1629The incidence of perturbed gastrointestinal integrity, as well as resulting
systemic immune responses and gastrointestinal symptoms, otherwise known as
exercised-induced gastrointestinal syndrome (EIGS), is common among individuals
who partake in prolonged exercise. EIGS may cause the translocation of
pathogenic material, including whole bacteria and bacterial endotoxins, from the
lumen into circulation, which may progress into clinical consequences such as
sepsis, and potentially subsequent fatality. However, further inves...

A Genotype-Phenotype Model for Predicting Resistance Training Effects
on Leg Press Performance
This study develops a comprehensive genotype-phenotype model for predicting the
effects of resistance training on leg press performance. A cohort of physically
inactive adults (N=193) underwent 12 weeks of resistance training, and
measurements of maximum isokinetic leg press peak force, muscle mass, and
thickness were taken before and after the intervention. Whole-genome genotyping
was performed, and genome-wide association analysis identified 85 novel SNPs
significantly associated with changes in leg press strength after training. A
prediction model was...

The Frequency and Severity of Gastrointestinal Symptoms in Rugby
Players
This study aimed to assess the self-reported frequency and severity of
gastrointestinal symptoms (GIS) at rest and around rugby training and match play
in male and female rugby union players. An online questionnaire was sent to
registered rugby union players (sevens or fifteens). Thirteen GIS were assessed
alongside perceptions of appetite around rugby and rest using Likert and visual
analog scales. Questions investigating a range of medical and dietary factors
were included. Three hundred and twenty-five players (male n=271, female
n=54) participated in...

Effects of 24-week Polarized Training vs. Threshold Training in Obese
Male Adults
Int J Sports Med DOI: 10.1055/a-2123-0851The combination of high volume of moderate-intensity continuous training with a
low volume of high-intensity interval training improved body composition and
physical capacities in individuals with obesity. However, polarized training
(POL) has never been used in adult men with obesity. Thus, the purpose of this
study was to investigate changes in body composition and physical capacities
induced by a 24-week POL or threshold (THR) program in obese male adults. Twenty
male patients (mean age 39.8±6.3 yrs; mean body mass in...

Does Age Influence Gastrointestinal Status Responses to
Exertional-heat Stress?
Int J Sports Med DOI: 10.1055/a-2195-3131This meta-data exploration aimed to determine the impact of exertional-heat
stress (EHS) on gastrointestinal status of masters age and young adult endurance
athletes. Sixteen MASTERS (mean: 44y) and twenty-one YOUNG (26y) recreational
endurance athletes completed 2 h of running at 60%
˙V O2max in 35˚C ambient
conditions. Blood samples were collected pre-, immediately and 1 h post-EHS, and
analyzed for markers of exercise-induced gastrointestinal syndrome (EIGS).
Thermo-physiological measures and gastrointest...

3-min All-out Test to Evaluate Aerobic and Anaerobic Indexes in Court
Team Sports
This study aimed to test the reproducibility of the 3-min all-out effort applied
using shuttle running and compare its values to aerobic parameters. On the first
day, 14 futsal players underwent an exhaustive test to determine the maximal
incremental speed (MIS) and anaerobic threshold (AnT). On the second day, the
participants performed the 3-min all-out effort (n=14), which was
repeated after 48 h (third day) to test its reproducibility
(n=11). Peak oxygen consumption (V̇ O2PEAK) and peak
blood lactate concentrations ([La-]) were determined from 3-m...

Comparison Of Different Theoretical Models”
Int J Sports Med 2024; 45: 79-79 DOI: 10.1055/a-2209-5191Dear Editor,I read with interest the study by Ruiz-Alias et al. on different critical power
models in running 1. The study offers valuable
insights into the application of critical power in running, highlighting
considerable discrepancies between different methods of estimation. While the work
is commendable, it leaves room for questions regarding the methodology applied and
the interpretation of the results. The omission of each participant’s mean
power of the trials in the study, in combination with a re...

Parenteral Iron Therapy: Examining Current Evidence for Use in
Athletes
Int J Sports Med DOI: 10.1055/a-2211-0813A high prevalence of iron deficiency exists in athlete populations. Various
mechanisms, including increased losses through sweat, haemolysis, haematuria,
and gastrointestinal micro-ischemia; inadequate dietary intake; and transient
exercise-induced increases in the regulatory hormone, hepcidin, contribute to
the increased prevalence in athletes. Indeed, hepcidin has been shown to peak
around 3–6 hours post-exercise, limiting iron absorption from
the gut. As the practitioner’s ability to control losses is limited, the
...

HIIT Induces Stronger Shifts within the Peripheral T Cell Compartment
Independent of Sex
Int J Sports Med DOI: 10.1055/a-2197-0882Acute exercise induces changes within the T-cell compartment, especially in
cytotoxic CD8+ memory subsets, depending on exercise
intensity and duration. It is unclear whether exercise-induced changes in major
T-cell subsets differ in response to acute high-intensity interval training
(HIIT) or moderate-intensity continuous training (MICT) and whether sex-specific
effects exist. Twenty-four recreationally active runners (females: n=12,

Immunometabolic and Vascular Health Responses among High Endurance
Trained Subjects
In this study, we aimed to examine the impact of high endurance training on
vascular health parameters and immune-endocrine responses against modified
low-density lipoprotein (LDL) particles. This observational, cross-sectional
study included high endurance-trained and healthy non-trained subjects. Vascular
ultrasound was used to assess vascular health parameters based on carotid
intima-media thickness and endothelial function (flow-mediated dilation).
Enzyme-linked immunosorbent assays were used to measure interleukin (IL)-8 and
IL-10, autoantibody isot...
