CircRNA Larp4b/miR-298-5p/Mef2c Regulates Cardiac
Hypertrophy Induced by Angiotensin II
Int J Sports Med DOI: 10.1055/a-2172-8171Cardiac hypertrophy (CH) is an early marker in the clinical course of heart
failure. Circular RNAs (circRNAs) play important roles in human disease.
However, the role of circ_Larp4b in myocardial hypertrophy has not been studied.
Angiotensin II (Ang II) treated HL-1 cells to induce a CH cell model.
Quantitative real-time polymerase chain reaction was used to detect the
expression of circ_Larp4b, microRNA-298-5p, and myocyte enhancer factor 2
(Mef2c). Western blot detected the protein level of alpha-actinin-2 (ACTN2),

Evaluation of Hip Characteristics in Baseball and Softball Athletes
with and Without Throwing Arm Pain
This study aimed to determine
differences between hip rotational range of motion and strength based on the
presence of throwing-arm pain (yes/no) and throwing sport
(baseball/softball). We hypothesized those experiencing pain would
display decreases in hip range of motion and strength, and that softball players
would display greater range of motion than baseball, but less strength based on
sex-specific characteristics. Forty-four baseball (13±2 years,
165.2±13.0 cm, 58.5±13.4 kg) and 50 softball
players (13±2 years, 160.9±11.2 cm,

Resistance Training Intensity Prescription Methods Based on Lifting
Velocity Monitoring
Int J Sports Med DOI: 10.1055/a-2158-3848Resistance training intensity is commonly quantified as the load lifted relative
to an individual's maximal dynamic strength. This approach, known as
percent-based training, necessitates evaluating the one-repetition maximum (1RM)
for the core exercises incorporated in a resistance training program. However, a
major limitation of rigid percent-based training lies in the demanding nature of
directly testing the 1RM from technical, physical, and psychological
perspectives. A potential solution that has gained popularity in th...

Differences of Bone Mineral Density by Characteristics of Sports in
Amenorrheic Athletes
Int J Sports Med DOI: 10.1055/a-2161-5668Hypothalamic amenorrhea leads to a hypoestrogenic state, causing decreased bone
mineral density (BMD), while strong impact loading on bone has been shown to
increase BMD. The purpose of this study is to compare BMD in female athletes
based on menstrual status and their sports/events by impact loading
characteristics. BMD at the lumbar spine was measured by dual-energy X-ray
absorptiometry and hormone level. The subjects were classified into four groups
and BMD and hormone levels were compared among the four groups, which we...

Running Functional Threshold versus Critical Power: Same Concept but
Different Values
Int J Sports Med DOI: 10.1055/a-2155-6813The aims of this study were (i) to estimate the functional threshold power (FTP)
and critical power (CP) from single shorter time trials (TTs) (i. e. 10,
20 and 30 minutes) and (ii) to assess their location in the
power-duration curve. Fifteen highly trained athletes randomly performed ten TTs
(i. e. 1, 2, 3, 4, 5, 10, 20, 30, 50 and 60 minutes). FTP was
determined as the mean power output developed in the 60-min TT, while CP was
estimated in the running power meter platform according to the
manufacturer...

An Update Of The Allen & Coggan Equation To Predict 60-Min
Power Output In Cyclists Of Different Performance Levels
Int J Sports Med DOI: 10.1055/a-2079-1363The Allen & Coggan protocol suggests that 95% of the power output
during a 20-min time trial is a valid surrogate for 60-min maximal power. The
validity of this concept has not been studied previously in cyclists with
different performance levels. As a result, we classified 120 cyclists in our
study as recreationally trained, trained, well trained or professional, based on
their maximal oxygen consumption. Participants performed a functional threshold
power testing protocol based on a 20-min time trial and a 60-min time...
