Interval Training?
Int J Sports Med DOI: 10.1055/a-2256-0285The aim of this study was to determine the effects of subtetanic neuromuscular
electrical stimulation combined with voluntary exercise between repeated Wingate
tests on sprint exercise performance and blood lactate accumulation during
sprint interval training. Fifteen healthy young males volunteered. After 1-min
baseline, participants underwent the Wingate test twice. They performed a 4-min
intervention between tests: neuromuscular electrical stimulation with
free-weight cycling or voluntary cycling alone [43.6 (8.0) watts]...

The Influence of Pedaling Frequency on Blood Lactate Accumulation in
Cycling Sprints
In this study, we investigated the impact
of pedaling frequency on blood lactate accumulation during 10-second maximal
isokinetic cycling sprints. Thirteen trained males completed five 10-second
maximal isokinetic cycling sprints on a bicycle ergometer at different pedaling
frequencies (90 rpm, 110 rpm, 130 rpm, 150 rpm, 170 rpm) with continuous power
and frequency measurement. Capillary blood samples were taken pre-exercise and
up to 30 minutes post-exercise to determine the maximum blood lactate
concentration.Blood lactate accumulation was ...

Cardiomyocyte Adaptation to Exercise: K+ Channels,
Contractility and Ischemic Injury
Int J Sports Med DOI: 10.1055/a-2296-7604Cardiovascular disease is a leading cause of morbidity and mortality, and
exercise-training (TRN) is known to reduce risk factors and protect the heart
from ischemia and reperfusion injury. Though the cardioprotective effects of
exercise are well-documented, underlying mechanisms are not well understood.
This review highlights recent findings and focuses on cardiac factors with
emphasis on K+ channel control of the action potential duration
(APD), β-adrenergic and adenosine regulation of cardiomyocyte function, and

Injury Risk Analysis among Judo Athletes with Intellectual
Disabilities
Int J Sports Med DOI: 10.1055/a-2280-4963The main aim of this study was to evaluate injury prevalence, incidence rate, and
burden in judo athletes with intellectual disabilities (ID) who participate in
international competitions. This retrospective cross-sectional study analyzed
data from the past year for 182 judo athletes with ID. Data was collected using
a self-reported questionnaire, adapted from previous research, that included
questions about injuries impacting training or competition, injury type,
mechanism, severity, diagnosis, and location on the body. Th...

Altered Cervical Spine Position Results in Decreased Eccentric
Shoulder Rotation Strength
Int J Sports Med DOI: 10.1055/a-2281-1396Overhead athletes require strenuous shoulder activity in nonneutral cervical
spine positions to eccentrically decelerate the throwing/striking arm following
ball release/contact. We therefore aimed to compare eccentric shoulder rotation
strength through a 90° arc between neutral and rotated positions. Fifty-two
participants (19 M, 34 F 170±10 cm; 73±18 kg, 21.9±2.9 years) without shoulder
or cervical spine pathology participated. Isokinetic eccentric shoulder rotation
strength was measured through a 90° arc wit...

High Prevalence of Seasonal and Current Groin Problems in Rink Hockey
Players
Int J Sports Med DOI: 10.1055/a-2267-0262Groin problems are common in multidirectional sports. The aim of the present
study is to assess seasonal, current, and trends for groin problems in rink
hockey players, irrespective of their playing position, age, or gender. Rink
hockey players from three countries [n=446 (162 female, 284 male)] were invited
to participate in an online questionnaire. This form evaluated the prevalence of
groin problems (time-loss and non-time-loss) for the 2022–2023 season, as well
as monthly prevalence of groin problems (time-loss and no...

Effect of Aerobic Training with Blood Flow Restriction on Strength
and Hypertrophy: A Meta-analysis
In conclusion, for strength
gains very low-quality evidence was found to support no superiority between
LI-BFR and HI-BFR compared to LI and HI, respectively. For muscle hypertrophy,
superiority of LI was found compared to LI-BFR, with a very low level of
evidence. [...] Georg Thieme Verlag Rüdigerstraße 14, 70469 Stuttgart, GermanyArticle in Thieme eJournals: Table of contents | Abstract | Full text (Source: International Journal of Sports Medicine)

Exercise-induced Hypertension and Carotid Intima-media Thickness in
Male Marathon Runners
This study aimed to identify the relationship between exercise-induced
hypertension and carotid artery intima-media thickness in long-distance runners.
Sixty healthy male runners aged 40 to 60 years were assigned to the following
three groups based on resting blood pressure and maximal systolic blood pressure
during a maximal exercise test: normal blood pressure response, exercise-induced
hypertension, and complex hypertension. An exaggerated systolic blood pressure
response was defined as a maximal systolic blood pressure+≥+210 mmHg during the
maxim...

Association between Physical Activity and Menstrual Cycle Disorders
in Young Athletes
Int J Sports Med DOI: 10.1055/a-2278-3253Our study aims to evaluate clinical predictors of menstrual cycle disorders in
female athletes who compete in running disciplines. This is a prospective
observational study. Women were recruited between January and May 2022.
Fifty-three patients were enrolled and completed a questionnaire about menstrual
cycle, physical activity, and food habit characteristics. Of the women in our
population, 39.6% had menstrual irregularities and reported a significantly
higher number of kilometers run per week (67 vs. 35, p:0.02). The num...

Breathing Motion Pattern in Cyclists: Role of Inferior against
Superior Thorax Compartment
We examined whether and how experience with
cycling training modifies the thoracoabdominal motion patterns. We utilized
optoelectronic plethysmography to monitor ten trained male cyclists and compared
them to ten physically active male participants performing breathing maneuvers.
Cyclists then participated in a self-paced time trial to explore the similarity
between that observed during resting breathing. From the 3D coordinates of 32
markers positioned on each participant’s trunk, we calculated the percentage of
contribution of the superior thorax, in...
