Adults
This study aimed to validate the
6-minute run test in adults, comparing it to the established shuttle run test,
and to create reference equations. The cross-over design involved healthy adults
aged 18–65 undertaking both tests, separated by a two-hour interval. The
6-minute run test required participants to run around a volleyball court for six
minutes, aiming to maximize distance covered. The shuttle run involved
participants covering 20 meters in defined time intervals at increasing speeds.
Parameters measured included 6-minute run test distance, hea...

Standardized vs. Relative Intensity in CrossFit
This study aimed to compare the acute
response in total repetitions as a measurement of performance, jump ability,
physiological demand (heart rate and blood lactate), and perceived effort
considering the participants’ strength level with individualized
intensity in CrossFit. Thirty-five participants were assessed and asked to
participate on two separate days in a standardized and relative ‘As Many
Repetitions As Possible’ (AMRAP) CrossFit circuit. Both AMRAPs comprised
strength, gymnastic and aerobic exercises, although only strength was

Inter-repetition Rest Impact on Percentage of Repetition Completed at
Certain Velocity Loss
This study examined the impact of different inter-repetition rest (IRR)
configurations (zero seconds [IRR0], three seconds [IRR3], and self-selected
less than five seconds [SSIRR]) on estimating the number of repetitions (Nrep)
and the percentage of completed repetitions relative to the maximum number of
repetitions possible to failure (%rep) after reaching 10%,
20%, and 30% velocity loss thresholds (VLT). Eighteen men
completed three sessions, each with a different IRR configuration, separated by
48–72 hours. Single sets of repetitions to momentary ...

Reliability of the Maximal Lactate Accumulation Rate in
Rowers
Int J Sports Med DOI: 10.1055/a-2206-4959The maximal lactate accumulation rate (VLamax) has been linked to lactic
anaerobic performance. Hence, accurate and reliable assessment is crucial in
sport-specific performance testing. Thus, between-day reliability data of
rowing-specific VLamax assessment was examined. Seventeen trained rowers (eight
females and nine males; 19.5±5.2 yrs;
1.76±0.08 m; 70.2±8.9 kg;
V̇O2max: 54±13 ml/min/kg)
performed 20-s sprint tests on two separate days (one week apart) on a rowing
ergometer. VLamax, pea...

Neural Adjustments during Repeated Braking and Throttle Actions on a
Motorcycle Setup
In conclusion, contrarily to other
studies, our results bring forward that when mimicking motorcycling
brake-pulling and gas throttle actions, supraspinal neural mechanisms primarily
limit the duration of the performance. [...] Georg Thieme Verlag Rüdigerstraße 14, 70469 Stuttgart,

Electromyographic Activity of Lower Limb Muscles during Ankle
Destabilizing Tests
This study highlights the effectiveness of the destabilizing device to involve
specifically the peroneal muscles when performing various functional tests. This
device should be used by clinicians to be more specific to the stabilizers of
the ankle joint during functional exercises. [...] Georg Thieme Verlag Rüdigerstraße 14, 70469 Stuttgart,

Relative Match Load in Young Professional Soccer Players during
Soccer-7 and Soccer-11
Int J Sports Med DOI: 10.1055/a-2192-8704The aim of this study was to analyze the differences in internal and external
load during Soccer-7 and Soccer-11, comparing positional requirements and
neuromuscular fatigue in both modalities. Twenty-four young soccer players were
monitored in Soccer-7 and Soccer-11 matches using global positioning systems.
Total distance covered (TD), distance covered at high speed (HSR), distance
covered at very high speed (VHSR), peak speed, accelerations (Acc) and
decelerations (Dec) and rate of perceived exertion (RPE) were recorded

Practical Aspects of Cardiopulmonary Exercise Testing in
Children
Int J Sports Med DOI: 10.1055/a-2191-0518The use of cardiopulmonary exercise testing (CPET) in pediatrics provides
critical insights into potential physiological causes of unexplained
exercise-related complaints or symptoms, as well as specific pathophysiological
patterns based on physiological responses or abnormalities. Furthermore, CPET
helps evaluate exercise performance in children with chronic
(lung/heart) diseases. For instance, it can ascertain any adverse
reaction to exercise and estimate the effects of specific treatment measures. It
affords a ...

Impact of Strength Training Intensity on Brain-derived Neurotrophic
Factor
Int J Sports Med DOI: 10.1055/a-2197-1201The present study employed a randomized crossover design to investigate the
effect of strength-training exercise at varying intensities on acute changes in
plasma brain-derived neurotrophic factor (BDNF) levels. Fourteen trained male
subjects (41.0±5.8 years old) were enrolled in the current study. The
strength-training protocol included bench press, leg press, and lat pull-down
exercises. Participants performed four sets with repetition failure at
60% or 80% of their one-repetition maximum (1RM), with a
two-minu...

Youth Injury Knowledge and Beliefs following Neuromuscular Training
Warm-up Implementation in Schools
Int J Sports Med DOI: 10.1055/a-2184-9201Neuromuscular training warm-up programs can reduce injury rates in youth sports,
but they often have poor uptake and adherence. Delivering such programs in
school physical education classes may provide greater public health benefit,
particularly if they promote improved injury knowledge and prevention beliefs
amongst students. The purpose of this secondary analysis of a large
cluster-randomized controlled trial was to understand how students’ (age
11–15 years) knowledge and beliefs change after exposure to an

EMG Analysis During Static Balance in Chronic Ankle Instability,
Coper and Controls
This study
aimed to compare muscle activity in the lower extremity and postural control
among individuals with CAI, copers and uninjured controls during a static
balance test. A total of 57 physically active participants were categorized into
three groups (CAI, copers and controls) and performed a single-leg balance test
with two visual conditions: eyes open and eyes closed. Muscle activity in six
lower extremity muscles and center of pressure (CoP) variables were recorded and
analyzed. Patients with CAI exhibited greater muscle activity in the medial

Load-velocity Relationship of the Bench Press Exercise is not
Affected by Breast Cancer Surgery and Adjuvant Therapy
We examined the effect of breast cancer surgery and adjuvant therapy on the
relationship between bar velocity and relative intensity (load-velocity [L-V]
relationship) of the bench press (BP) exercise. Twenty-two breast cancer
survivors (age: 48.0±8.2 yr., relative strength:
0.40±0.08) completed a loading test up to the one-repetition maximum
(1RM) in the BP using a lightweight carbon bar. General and individual
relationships between relative intensity (%1RM) and mean propulsive
velocity (MPV) were studied. Furthermore, the mean test velocity

Energetics (and Mechanical Determinants) of Sprint and Shuttle
Running
Int J Sports Med DOI: 10.1055/a-2184-9007Unsteady locomotion (e. g., sprints and shuttle runs) requires additional
metabolic (and mechanical) energy compared to running at constant speed. In
addition, sprints or shuttle runs with relevant speed changes (e. g.,
with large accelerations and/or decelerations) are typically short in
duration and, thus, anaerobic energy sources must be taken into account when
computing energy expenditure. In sprint running there is an additional problem
due to the objective difficulty in separating the acceleration phase from a
...
