Running Test
Int J Sports Med DOI: 10.1055/a-1873-1829Force-velocity-power (FVP) profiling offers insights related to key factors that
may enhance or hinder sprinting performances. Whether the same FVP principles
could be applied to the sprinting portion of the 3-minute all-out test for
running (3MT) has not been previously investigated. Twenty moderately trained
participants volunteered for the study (age: 24.75 ±
3.58 yrs; height: 1.69±0.11 m; mass:
73.74±12.26 kg). After familiarization of all testing
procedures, participants completed: (i) a 40-m all-o...

Exercise Dose and Aerobic Fitness Response in Alzheimer ʼs Dementia:
Findings from the FIT-AD Trial
Int J Sports Med DOI: 10.1055/a-1639-2307The purpose of this study was to examine the effects of a 6-month cycling aerobic
exercise intervention on cardiorespiratory fitness and the dose-response
relationship in community-dwelling older adults with mild-to-moderate
Alzheimerʼs dementia. The FIT-AD trial was a single blind, 2-parallel group,
pilot randomized controlled trial. The aerobic exercise group participated in a
6-month, thrice weekly, moderate-vigorous intensity cycling intervention while
control group performed stretching. Cardiorespiratory fitness was e...

The reproducibility of 20-min time-trial performance on a virtual cycling platform.
This study aimed to analyse the reproducibility of mean power output during 20-min cycling time-trials, in a remote home-based setting, using the virtual-reality cycling software, Zwift. Forty-four cyclists (11 women, 33 men; 37 ± 8 years old, 180 ± 8 cm, 80.1 ± 13.2 kg) performed 3 x 20-min time-trials on Zwift, using their own setup. Intra-class correlation coefficient (ICC), coefficient of variation (CV) and typical error (TE) were calculated for the overall sample, split into 4 performance groups based on mean relative power output (25% quartiles) and sex. Mean ICC, TE and CV of mean power output between time-trials...

Differences in Training Characteristics Between Junior, Under 23 and
Professional Cyclists
Int J Sports Med DOI: 10.1055/a-1847-5414The aim was to compare the training characteristics of junior, under 23 and
professional road cyclists. Training data collected during the 2019 competitive
season of thirty male cyclists, divided into three age-related categories (JUN;
U23; PRO), were retrospectively analyzed for training characteristics, external
and internal training load. Higher duration per training session were observed
in PRO (2.6±0.3 h) compared to both U23 (2.2±0.3 h;
P<0.001) and JUN (2.0±0.2 h; P<0.001).

Clarifying the Link Between the Blood Lactate Concentration and
Cardiovascular Risk
Int J Sports Med DOI: 10.1055/a-1812-5840The blood lactate value at rest (Lacrest) is linked to cardiovascular
outcomes. It is unclear whether this association holds true in younger, healthy
subjects, especially as the pathophysiological connection between
Lacrest and cardiometabolic disease is not well understood. The
aim of this study is clarifying the link between Lacrest and
cardiovascular risk, and to study explanatory factors for the variance of
Lacrest concerning metabolism and physical activity in a
population of healthy patient-athletes. The...

Fecal microbiota monitoring in elite soccer players along the 2019-2020 competitive season
Int J Sports Med DOI: 10.1055/a-1858-1810Physical exercise affects the human gut microbiota that, in turn, influences athletes’ performance. The current understanding of how the microbiota of professional athletes changes along with different phases of training is sparse. We aim to characterize the fecal microbiota in elite soccer players along with different phases of a competitive season using 16S rRNA gene sequencing. Fecal samples were collected after the summer off-season period, the pre-season retreat, the first half of the competitive season, and the 8 weeks COVID-19 lockdown that interrupted the season 2019-2020....

Effects of Moderate Altitude Training Combined with Moderate or
High-altitude Residence
Int J Sports Med DOI: 10.1055/a-1885-4053We aimed to identify potential physiological and performance differences of
trained cross-country skiers (V˙o2max=60±4
ml ∙ kg–1 ∙ min–1)
following two, 3-week long altitude modalities: 1) training at moderate
altitudes (600–1700 m) and living at 1500 m (LMTM;N=8); and 2)
training at moderate altitudes (600–1700 m) and living at 1500 m with
additional nocturnal normobaric hypoxic exposures
(FiO2 =0.17;LHTM; N=8). All participants
conducted the same training throughout the alti...

Reliability of Running Economy Measurements: Influence of Shoe
Familiarisation
Int J Sports Med DOI: 10.1055/a-1820-7023The purpose was to investigate differences in reliability of running economy
measurements between familiar and unfamiliar shoes. Thirty-seven runners were
included who all ran in familiar and unfamiliar running shoes while running
economy was measured at steady state using a treadmill. Each participant was
tested on two different visits (three sessions in total), with two trials in
each of the three shoe conditions completed at each visit. Coefficient of
variation, standard deviation of differences, and limits of agreement ...

Hemodynamic Response During Different Set Configurations of a
Moderate-load Resistance Exercise
Int J Sports Med DOI: 10.1055/a-1843-8778We aimed to determine the cardiovascular responses to two different set
configuration resistance-exercise protocols during a knee extension composed of
40 repetitions with a 15RM load and a total resting time of 360 seconds.
Twenty-four healthy sport science students randomly performed two sessions: (a)
a long set configuration (LSC: 4 sets of 10 repetitions with 2 min rest between
sets), and (b) a short set configuration (SSC: 8 sets of 5 repetitions with 51 s
rest between sets). Before and during exercise, peak and mean v...

Movement Velocity as a Determinant of Actual Intensity in Resistance
Exercise
This study aimed to analyze the acute mechanical, metabolic and EMG response to
five resistance exercise protocols (REP) in the full squat (SQ) exercise
performed with two velocity conditions: maximal intended velocity (MaxV) vs.
half-maximal velocity (HalfV). Eleven resistance-trained men performed 10 REP (5
with each velocity conditions) in random order (72–96 h apart).
The REP consisted of three sets of 8–3 repetitions against
45–65% 1RM. The percent change in countermovement jump (CMJ)
height, velocity attained with the load that elicited a

Systematic Review of Innovative Diagnostic Tests for Chronic
Exertional Compartment Syndrome
Int J Sports Med DOI: 10.1055/a-1866-5957The diagnosis chronic exertional compartment syndrome is traditionally linked to
elevated intracompartmental pressures, although uncertainty regarding this
diagnostic instrument is increasing. The aim of current review was to evaluate
literature for alternative diagnostic tests. A search in line with PRISMA
criteria was conducted. Studies evaluating diagnostic tests for chronic
exertional compartment syndrome other than intracompartmental pressure
measurements were included. Bias and quality of studies were evaluated using ...
