One-on-one Transition Task
This study examined the training load on professional soccer players during
transition games performed with different bout durations and their effects on
speed and jump tests. Fourteen young soccer players played a transition game of
different bout durations: 15 (TG15), 30 (TG30), and 60
(TG60) seconds. Total distance covered (DC), accelerations and
decelerations above 1.0 and 2.5 m·s-2, rate of
perceived exertion (RPE), maximal heart rate (HRmax) and above
90% (HR>90), distance covered between
18.0–20.9 km·h-1 (DC

The Association between ACTN3 R577X Polymorphism and Range of
Motion: A Systematic Review and Meta-analysis
We examined the
effect of the ACTN3 R577X polymorphism on ROM through meta-analysis and
systematic review. Relevant studies published before April 14, 2022 were
identified from the PubMed database using the following keywords and Boolean
operators: (“flexibility” or “Joint Range of
Motion” or “Joint Flexibility” or “Range of
motion”) and (“ACTN3” or “alpha-actinin
3”). Studies that met the following criteria were included: (1)
published in English, (2) included human subjects, (3) provided ROM
measurements, and...

The Assessment of Affective Responses within Exercise Prescription: A
Narrative Review
Int J Sports Med DOI: 10.1055/a-2029-8337The assessment of affective responses (pleasure-displeasure) to exercise, is a
useful tool for tailoring exercise prescription. Ideally, the proper
prescription is a balance between minimizing risks, such as negative affect and
dropout, and maximizing gains, such as improvements in health and fitness.
Measuring affective responses to exercise facilitates the process of
self-regulation. When individuals have the autonomy to select the exercise
intensity, they are more likely to have a positive exercise experience and
...

High-intensity Actions in Elite Soccer: Current Status and Future
Perspectives
Int J Sports Med DOI: 10.1055/a-2013-1661Over the years, soccer has become more physically demanding; the number and
frequency of high-intensity actions have increased, and these activities are
decisive in determining the match outcome. Importantly, the reductionist
approach commonly used to analyze high-intensity actions does not contemplate a
more contextualized perspective on soccer performance. Traditionally, most
investigations have only provided quantitative data regarding sprints
(i. e. time, distances, frequency) without examining
“how” (e....

The Influence of Daily Exercise on Muscle Echo Intensity and
Stiffness in Young Women
This study aimed to investigate the effect of daily exercise on skeletal muscle
function, size, and quality in young women. Twenty-six young women participated
in this study, categorized into daily exercise and non-exercise groups. The
exercise group had performed exercise or training three times a week for more
than six months. Knee extension and flexion, plantar flexion, and dorsiflexion
peak torques were measured for muscle function. B-mode ultrasound images were
taken from the thigh and calf, and muscle thickness and echo intensity were
measured in t...

Effects of Kinesio Taping on Tuck Jump Performance in Competitive
Male Athletes
This study aimed to measure the acute effects of kinesio taping at different
stretches on tuck jump performance in active individuals. Seventy-five males
(23.01±2.24 years, 178.35±8.12 cm,
72.47±6.58 kg) were randomly distributed into three groups: (1)
kinesio taping without stretch, (2) kinesio taping with approximately
50% stretch, and (3) kinesio taping with approximately 75%
stretch. The tuck jump performance of all participants was determined at
baseline, immediately after applying kinesio taping, and 24 and 72 hours
later. The pa...

Exercise Changes Gut Microbiota: A New Idea to Explain that Exercise
Improves Autism
Int J Sports Med DOI: 10.1055/a-2018-2477The effect of exercise interventions on autism spectrum disorder (ASD) has been
demonstrated in many studies, and the discovery of a bidirectional relationship
between the gut microbiome (GM) and the central nervous system (CNS) has led to
the concept of the microbial gut-brain axis (MGBA) and has linked the abnormal
GM to a variety of neuropsychiatric disorders, autism being one of them.
Research on improving the GM through exercise is also starting to come into
focus. However, there are currently few studies on exercise i...

Moderate to Vigorous-intensity Continuous Training versus
High-intensity Interval Training for improving VO2max in women: A systematic
review and meta-analysis
Int J Sports Med DOI: 10.1055/a-2044-8952Traditional continuous training and high-intensity interval training (HIIT) can
increase maximal oxygen uptake (V̇O2max). However, there is
conflicting evidence regarding which form of training demonstrates the greatest
improvements to V̇O2max, and data in women is sparse. We
conducted a systematic review and meta-analyses to assess whether moderate to
vigorous-intensity continuous training (MVICT) or HIIT was superior at improving
V̇O2max in women. Randomised controlled and parallel
studies examined the infl...

Circulating Fatty Acid-binding Protein 4 Response to Acute Aerobic
Exercise in Healthy Men
This study aimed to investigate the association between changes in FABP4
concentration and hormone and metabolite levels during and after acute low- and
moderate-intensity aerobic exercise in healthy men. Eleven healthy men
(24.4±1.4 years) were administered three trials in random order: 1)
low-intensity aerobic exercise trial (LE trial; acute exercise at 40%
peak oxygen uptake [Vo2peak]+bed rest), 2) moderate-intensity
aerobic exercise trial (ME trial: acute exercise at
60%Vo2peak+bed rest), and 3) bed rest (Con trial).

Femur 3D-DXA Assessment in Female Football Players, Swimmers, and
Sedentary Controls
Int J Sports Med DOI: 10.1055/a-1928-9824Cortical and trabecular volumetric bone mineral density (vBMD), cortical
thickness and surface BMD (sBMD, density-to-thickness ratio) were analyzed in
the proximal femur of elite female football players and artistic swimmers using
three-dimensional dual-energy X-ray absorptiometry (3D-DXA) software and
compared to sedentary controls. Football players had significantly higher
(p<0.05) vBMD (mg/cm3) in the trabecular
(263±44) and cortical femur (886±69) than artistic swimmers
(224±43 and 844±89) and sedentary...

The Effects of Exercise Training on Plasma Volume Variations: A
Systematic Review
Int J Sports Med DOI: 10.1055/a-1667-6624The aim of this systematic review was to summarize the evidence on the acute and
long-term effects of exercise training on PV, in both trained and untrained
individuals and to examine associations between changes in %PVV and
change in physical/physiological performance. Despite the status of
participants and the exercise duration or intensity, all the acute studies
reported a significant decrease of PV (effect size: 0.85<d<3.45,
very large), and ranged between 7 and 19.9%. In untrained individuals,
most of s...

Regular Voluntary Running is Associated with Increased Tumor
Vascularization and Immune Cell Infiltration and Decreased Tumor Growth in
Mice
Int J Sports Med DOI: 10.1055/a-2008-7732Tumors present dysfunctional vasculature that limits blood perfusion and hinders
immune cells delivery. We aimed to investigate if regular voluntary running
promotes tumor vascular remodelling, improves intratumoral immune cells
infiltration and inhibits tumor growth. Tumors were induced in C57BL/6
male mice (n=28) by subcutaneous inoculation in the dorsal region with a
suspension of RM1 cells (1.5×105
cells/500 µL PBS) and randomly allocated into two
groups: sedentary (n=14) and voluntarily exercised on a whe...

Do Sports-related Concussions Induce Subsequent Injuries in Elite
Male Football Players?
Int J Sports Med DOI: 10.1055/a-1974-3965To assess the players’ risk of a subsequent injury after sustaining
concussive injuries and their return-to-competition in German professional
men’s football. A prospective injury database in the 1st
Bundesliga was created encompassing 7 seasons
(2014/15–2020/21). Cox proportional hazard model
analyzed whether a concussive injury increased the risk of a subsequent injury
in the first year after the index injury. 6,651 injuries were reported
(n=182 concussive injuries). The incidence rate was 0.15 (95% CI
