Determinants of V ̇+O2peak Changes After Aerobic Training
in Coronary Heart Disease Patients
This study aimed to highlight the ventilatory and circulatory determinants of
changes in ˙VO2peak after exercise-based cardiac rehabilitation (ECR)
in patients with coronary heart disease (CHD). Eighty-two CHD patients
performed, before and after a 3-month ECR, a cardiopulmonary exercise testing
(CPET) on a bike with gas exchanges measurements (˙VO2peak, minute
ventilation, i. e., ˙VE), and cardiac output (Q˙c). The arteriovenous difference
in O2 (C(a-v¯)O2) and the alveolar capillary gradient in
O2 (PAi-aO2) were calculated using Fick’s laws....

Classification of Male Athletes Based on Critical
Power
This study aimed to classify male athletes based on their performance levels
derived from running critical power (CP) using the 9/3-minute Stryd CP test,
enabling customized training strategies and goal setting. Twenty-four trained
athletes underwent the 9/3-minute running CP test on a certified 400-m athletics
track. Hierarchical cluster analysis using Ward's method categorized
athletes based on CP into distinct performance tiers. Three clusters were
identified with centroids of 3.87±0.12, 4.45±0.17, and 5.14±0.29 W/kg. Five
performance tiers were ...

Right Ventricular Structure and Function in Adolescent Athletes: A 3D
Echocardiographic Study
Int J Sports Med DOI: 10.1055/a-2259-2203The aim of this study was to characterize the right ventricular (RV) contraction
pattern and its associations with exercise capacity in a large cohort of
adolescent athletes using resting three-dimensional echocardiography (3DE). We
enrolled 215 adolescent athletes (16±1 years, 169 males, 12±6 hours of
training/week) and compared them to 38 age and sex-matched healthy, sedentary
adolescents. We measured the 3DE-derived biventricular ejection fractions (EF).
We also determined the relative contributions of longitudinal E...

The Variability of the Components of Fitness along the Menstrual
Cycle
This study aims to determine the variability of the components of fitness along
the menstrual cycle (MC) of physically active eumenorrheic women. Fifteen
subjects were monitored along two consecutive MCs through the calendar-based
counting method in combination with a urine luteinizing hormone surge kit.
Subjects were tested at the early follicular phase (EFP), pre-ovulatory or late
follicular phase (LFP), and post-ovulatory or mid-luteal phase (MLP). In each
session, the back squat one-repetition maximum (1-RM), maximum fat oxidation
(MFO), maximum oxyg...

Left Ventricular Hypertrophy in Male and Female Judo
Athletes
Int J Sports Med DOI: 10.1055/a-2252-1239Changes in cardiac geometry develop after intense and prolonged training. Left
ventricular enlargement, increased relative wall thickness, and growing mass of
the left ventricle occur after strenuous exercise. Combat sports such as judo
can lead to left ventricular hypertrophy. Previous studies have found that there
are differences in left ventricular chamber size and thickness between the
sexes, with female athletes having smaller wall diameters and less hypertrophy
than male athletes. The research aims to examine heart mu...

Effects of a Transoceanic Rowing Challenge on Cardiorespiratory
Function and Muscle Fitness
Int J Sports Med DOI: 10.1055/a-2205-1849Ultra-endurance sports and exercise events are becoming increasingly popular for
older age groups. We aimed to evaluate changes in cardiac function and physical
fitness in males aged 50–60 years who completed a 50-day transoceanic rowing
challenge. This case account of four self-selected males included electro- and
echo-cardiography (ECG, echo), cardiorespiratory and muscular fitness measures
recorded nine months prior to and three weeks after a transatlantic team-rowing
challenge. No clinically significant changes to myo...

The Sleep Parameters of Olympic Athletes: Characteristics and
Assessment Instruments
Int J Sports Med DOI: 10.1055/a-2233-0323This systematic review aims to identify the sleep parameters of Olympic athletes
and the instruments used to assess and monitor the sleep of these athletes. The
search was conducted until February 2023 and was performed in PubMed, Web of
Science, and Scopus databases. This systematic review has included studies that
investigated at least one of the following sleep parameters: total sleep time
(TST), sleep onset latency (SOL), sleep efficiency (SE), awakenings after sleep
onset (WASO), quality of sleep, daytime sleepiness, a...

Innovations in the Assessment of Skeletal Muscle Health: A Glimpse
into the Future
Int J Sports Med DOI: 10.1055/a-2242-3226Skeletal muscle is the largest organ system in the human body and plays critical
roles in athletic performance, mobility, and disease pathogenesis. Despite
growing recognition of its importance by major health organizations, significant
knowledge gaps remain regarding skeletal muscle health and its crosstalk with
nearly every physiological system. Relevant public health challenges like pain,
injury, obesity, and sarcopenia underscore the need to accurately assess
skeletal muscle health and function. Feasible, non-invasive t...

Implications of Heat Stress-induced Metabolic Alterations for
Endurance Training
Int J Sports Med DOI: 10.1055/a-2251-3170Inducing a heat-acclimated phenotype via repeated heat stress improves exercise
capacity and reduces athletes̓ risk of hyperthermia and heat illness. Given the
increased number of international sporting events hosted in countries with
warmer climates, heat acclimation strategies are increasingly popular among
endurance athletes to optimize performance in hot environments. At the tissue
level, completing endurance exercise under heat stress may augment endurance
training adaptation, including mitochondrial and cardiovascula...

Difference of Knee Strength Recovery Between Revision and Primary ACL
Reconstruction
Int J Sports Med DOI: 10.1055/a-2253-0103Different grafting procedures are available to restore knee stability after
revision anterior cruciate ligament (ACL) reconstruction. We compared knee
strength recovery between ACL revision surgery and primary reconstruction. One
hundred and ten patients with ACL revision surgery were matched with 110
patients with primary reconstruction based on the graft procedure. The
isokinetic knee strength had been assessed for the first 9 months post-surgery.
Knee laxity, function, and activity score were also evaluated. Limb symmetr...

An Epidemiologic Comparison of Injuries to Skiers and Snowboarders
Treated at United States Emergency Departments, 2000 –2019
Int J Sports Med DOI: 10.1055/a-2240-7747Skiing and snowboarding are popular competitive and recreational sports that can
be associated with significant injury. Previous studies of skiing and
snowboarding injuries have been conducted, but studies evaluating injury types
and patterns over long periods of time are needed to drive effective injury
prevention efforts. We hypothesized that injury patterns would differ among
snowboarders and skiers and that the number of injuries remained constant over
time. This is a retrospective study of patients presenting with skii...

Time-course Changes of Field- and Laboratory-based Performance
Indicators in Junior Cyclists Through a Season
This study aimed to assess the seasonal evolution of field-based and
laboratory-based performance indicators in cyclists. Thirteen Junior male road
cyclists (age 17.4±0.5 years) were followed up during a season, which
was divided in three phases: early season (involving mainly training sessions),
mid-season (including the first competitions), and late season (including the
major competitions of the season). During each phase, field-based power output
data were registered for the assessment of maximum mean power values, and
laboratory-based endurance (ra...

Effects of Eccentric Phase Velocity on Bench Press Concentric Bar
Velocity in the Young and Elderly
This study aimed to investigate the impact of bar velocity during the eccentric
phase on subsequent concentric performance in the young and elderly. Twelve
elderly women (65.2+4.2 years) and 16 young women (23.1+2.1
years) were randomly assigned to four experimental conditions that combined
high-velocity eccentric actions (HVECC; maximum velocity) and
moderate-velocity eccentric actions (MVECC; 2.0 s), using
30% and 60% of their 1-repetition maximum (1RM) on the Smith
machine bench press. Measurements of mean propulsive velocity (MPV), peak
