text: "Abstract\r\n Purpose\r\n
\ Wearables serve to quantify the on-court activity in intermittent
sports such as field hockey (FH). Based on objective data, benchmarks can be determined
to tailor training intensity and volume. Next to average and accumulated values,
the most intense periods (MIPs) during competitive FH matches are of special interest,
since these quantify the peak intensities players experience throughout the intermittent
matches. The aim of this study was to retrospectively compare peak intensities
between training and competition sessions in a male FH team competing in the first
german division.\r\n \r\n Methods\r\n
\ Throughout an 8-week in-season period, 372 individual activity
datasets (144 datasets from competitive sessions) were recorded using the Polar
Team Pro sensor (Kempele, Finland). MIPs were calculated applying a rolling window
approach with predefined window length (1–5 min) and calculated for Total distance,
High-Intensity-Running distance (> 16 km/h), Sprinting distance (> 20 km/h)
and Acceleration load. Significant differences between training and competition
MIPs were analysed through non-parametric statistical tests (P < 0.05).\r\n
\ \r\n Results\r\n
\ Analyses revealed higher MIPs during competition for all
considered outcomes (P < 0.001). Effect size estimation
revealed strongest effects for sprinting distance (d = 1.89
to d = 1.22) and lowest effect sizes for acceleration
load (d = 0.92 to d = 0.49).\r\n
\ \r\n Conclusion\r\n
\ The present findings demonstrate that peak intensities during
training do not reach those experienced during competitive sessions in a male
FH team. Training routines such as manipulations of court-dimensions and team
sizes might contribute to this discrepancy. Coaches should compare training and
competition intensities to recalibrate training routines to optimize athletes’
preparation for competition.\r\n "

text: 'Repetitive TMS (rTMS) with a frequency of 5-10~Hz is widely used for language
mapping. However, it may be accompanied by discomfort and is limited in the number
and reliability of evoked language errors. We, here, systematically tested the
influence of different stimulation frequencies (i.e., 10, 30, and 50 Hz) on tolerability,
number, reliability, and cortical distribution of language errors aiming at improved
language mapping. 15 right-handed, healthy subjects (m~=~8, median age: 29 yrs)
were investigated in two sessions, separated by 2-5 days. In each session, 10,
30, and 50 Hz rTMS were applied over the left hemisphere in a randomized order
during a picture naming task. Overall, 30 Hz rTMS evoked significantly more errors
(20 $\pm$ 12{%}) compared to 50 Hz (12 $\pm$ 8{%}; p {\textless}.01), whereas
error rates were comparable between 30/50 and 10~Hz (18 $\pm$ 11{%}). Across all
conditions, a significantly higher error rate was found in Session 1 (19 $\pm$
13{%}) compared to Session 2 (13 $\pm$ 7{%}, p {\textless}.05). The error rate
was poorly reliable between sessions for 10 (intraclass correlation coefficient,
ICC~=~.315) and 30 Hz (ICC~=~.427), whereas 50 Hz showed a moderate reliability
(ICC~=~.597). Spatial reliability of language errors was low to moderate with
a tendency toward increased reliability for higher frequencies, for example, within
frontal regions. Compared to 10~Hz, both, 30 and 50 Hz were rated as less painful.
Taken together, our data favor the use of rTMS-protocols employing higher frequencies
for evoking language errors reliably and with reduced discomfort, depending on
the region of interest.'

text: "Abstract\r\nPurpose\r\nSpace
flight and bed rest (BR) lead to a rapid decline in exercise capacity. Whey protein
plus potassium bicarbonate diet-supplementation (NUTR) could attenuate this effect
by improving oxidative metabolism. We evaluated the impact of 21-day BR and NUTR
on fatigue resistance of plantar flexor muscles (PF) during repeated shortening
contractions, and whether any change was related to altered energy metabolism
and muscle oxygenation.\r\n\r\nMethods\r\nTen
healthy men received a standardized isocaloric diet with (n = 5)
or without (n = 5) NUTR. Eight bouts of 24 concentric
plantar flexions (30 s each bout) with 20 s rest between bouts were employed.
PF muscle size was assessed by means of peripheral quantitative computed tomography.
PF muscle volume was assessed with magnetic resonance imaging. PF muscle force,
contraction velocity, power and surface electromyogram signals were recorded during
each contraction, as well as energy metabolism (31P nuclear
magnetic resonance spectroscopy) and oxygenation (near-infrared spectroscopy).
Cardiopulmonary parameters were measured during an incremental cycle exercise
test.\r\n\r\nResults\r\nBR
caused 10–15% loss of PF volume that was partly recovered 3 days after re-ambulation,
as a consequence of fluid redistribution. Unexpectedly, PF fatigue resistance
was not affected by BR or NUTR. BR induced a shift in muscle metabolism toward
glycolysis and some signs of impaired muscle oxygen extraction. NUTR did not attenuate
the BR-induced-shift in energy metabolism.\r\n\r\nConclusions\r\nTwenty-one
days’ BR did not impair PF fatigue resistance, but the shift to glycolytic metabolism
and indications of impaired oxygen extraction may be early signs of developing
reduced muscle fatigue resistance.\r\n"

text: The effectiveness of whey protein plus potassium bicarbonate-enriched
diet (WP+KHCO3) in mitigating disuse-induced changes in muscle
fiber oxidative capacity and capillarization was investigated in a 21-day crossover
design bed rest study. Ten healthy men (31 ± 6 yr) once received WP+KHCO3
and once received a standardized isocaloric diet. Muscle biopsies were taken 2
days before and during the 19th day of bed rest (BR) from the soleus (SOL) and
vastus lateralis (VL) muscle. Whole-body aerobic power (V̇o2 max),
muscle fatigue, and isometric strength of knee extensor and plantar flexor muscles
were monitored. Muscle fiber types and capillaries were identified by immunohistochemistry.
Fiber oxidative capacity was determined as the optical density (OD) at 660 nm
of succinate dehydrogenase (SDH)-stained sections. The product of fiber cross-sectional
area and SDH-OD (integrated SDH) indicated the maximal oxygen consumption of that
fiber. The maximal oxygen consumption supported by a capillary was calculated
as the integrated SDH in its supply area. BR reduced isometric strength of knee
extensor muscles ( P < 0.05), and the fiber oxidative capacity ( P < 0.001)
and V̇o2 max ( P = 0.042), but had no significant impact
on muscle capillarization or fatigue resistance of thigh muscles. The maximal
oxygen consumption supported by a capillary was reduced by 24% in SOL and 16%
in VL ( P < 0.001). WP+KHCO3 attenuated the disuse-induced
reduction in fiber oxidative capacity in both muscles ( P < 0.01). In conclusion,
following 19 days of bed rest, the decrement in fiber oxidative capacity is proportionally
larger than the loss of capillaries. WP+KHCO3 appears to
attenuate disuse-induced reductions in fiber oxidative capacity.

text: 'We examined, in immobilization, the effect of a diet high in sodium
chloride (NaCl) on bone markers, nitrogen balance, and acid-base status. Eight
healthy male test subjects participated in a 14-day head-down-tilt bed rest (HDBR)
study. During the bed rest period they received, in a randomized crossover design,
a high (7.7 meq Na+/kg body wt per day) and a low (0.7 meq
Na+/kg body wt per day) NaCl diet. As expected, 24-h excretion
of urinary calcium was significantly greater in the high-NaCl-intake HDBR phase
than in the low-NaCl-intake HDBR phase ( P < 0.001). High NaCl intake caused
a 43–50% greater excretion of the bone resorption markers COOH- (CTX) and NH2-
(NTX) terminal telopeptide of type I collagen in HDBR than low NaCl in HDBR (CTX/NTX:
P < 0.001). Serum concentrations of the bone formation markers bone-specific
alkaline phosphatase (bAP) and NH2-terminal propeptide of
type I procollagen (PINP) were identical in both NaCl intake phases. High NaCl
intake led to a more negative nitrogen balance in HDBR ( P < 0.001). Changes
were accompanied by increased serum chloride concentration ( P = 0.008), reduced
blood bicarbonate ( P = 0.017), and base excess ( P = 0.009) whereas net acid
excretion was lower during high than during low NaCl intake in immobilization
( P < 0.001). High NaCl intake during immobilization exacerbates disuse-induced
bone and muscle loss by causing further protein wasting and an increase in bone
resorption. Changes in the acid-base status, mainly caused by disturbances in
electrolyte metabolism, seem to determine NaCl-induced degradation processes.'
