Abstract: Sawyer, JC, Wood, RJ, Davidson, PW, Collins,
SM, Matthews, TD, Gregory, SM, and Paolone, VJ. Effects of a short-term
carbohydrate-restricted diet on strength and power performance. J
Strength Cond Res 27(8): 2255–2262, 2013—The purpose of the study was
to examine the effects of switching from a habitual diet to a
carbohydrate-restricted diet (CRD) on strength and power performance in trained
men (n = 16) and women (n = 15). Subjects performed
handgrip dynamometry, vertical jump, 1RM bench press and back squat,
maximum-repetition bench press, and a 30-second Wingate anaerobic cycling test
after consuming a habitual diet (40.7% carbohydrate, 22.2% protein, and 34.4%
fat) for 7 days and again after following a CRD (5.4% carbohydrate, 35.1%
protein, and 53.6% fat) for 7 days. Before both testing sessions, body weight
and composition were examined using bioelectrical impedance analysis. Three 2 ×
2 multiple analyses of variance were used to compare performance variables
between the habitual diet and CRD. Subjects consumed significantly fewer (p <
0.05) total kilocalories during the CRD (2,156.55 ± 126.7) compared with the
habitual diet (2,537.43 ± 99.5). Body mass decreased significantly (p <
0.05). Despite a reduction in body mass, strength and power outputs were
maintained for men and women during the CRD. These findings may have
implications for sports that use weight classes, and in which strength and
power are determinants of success. A CRD may be an alternative method for
short-term weight loss without compromising strength and power outputs. The use
of a 7-day CRD could replace weight loss methods employing severe dehydration
before competition.
Effects of 12-Week Proprioception
Training Program on Postural Stability, Gait, and Balance in Older Adults: A
Controlled Clinical Trial

Effects of 12-week proprioception training program on postural stability, gait,
and balance in older adults: a controlled clinical trial. J Strength
Cond Res 27(8): 2180–2188, 2013—The purpose of this study was to
evaluate the effect of a 12-week–specific proprioceptive training program on
postural stability, gait, balance, and fall prevention in adults older than 65
years. The present study was a controlled clinical trial. Forty-four community
dwelling elderly subjects (61–90 years; mean age, 78.07 ± 5.7 years) divided
into experimental (n = 20) and control (n = 24) groups.
The participants performed the Berg balance test before and after the training
program, and we assessed participants' gait, balance, and the risk of falling,
using the Tinetti scale. Medial–lateral plane and anterior–posterior plane
displacements of the center of pressure, Sway area, length and speed, and the
Romberg quotient about surface, speed, and distance were calculated in static
posturography analysis (EPS pressure platform) under 2 conditions: eyes open
and eyes closed. After a first clinical evaluation, patients were submitted to
12 weeks proprioception training program, 2 sessions of 50 minutes every week.
This program includes 6 exercises with the BOSU and Swiss ball as unstable
training tools that were designed to program proprioceptive training. The
training program improved postural balance of older adults in mediolateral
plane with eyes open (p < 0.05) and anterior–posterior plane
with eyes closed (p< 0.01). Significant improvements were
observed in Romberg quotient about surface (p < 0.05) and
speed (p < 0.01) but not about distance (p >
0.05). After proprioception training, gait (Tinetti), and balance (Berg) test
scores improved 14.66% and 11.47% respectively. These results show that 12
weeks proprioception training program in older adults is effective in postural
stability, static, and dynamic balance and could lead to an improvement in gait
and balance capacity, and to a decrease in the risk of falling in adults aged
65 years and older.
Experience in Resistance Training
Does Not Prevent Reduction in Muscle Strength Evoked by Passive Static
Stretching

Experience in resistance training does not prevent reduction in muscle strength
evoked by passive static stretching. J Strength Cond Res 27(8):
2304–2308, 2013—This study examined whether passive static stretching reduces
the maximum muscle strength achieved by different body segments in untrained
and resistance-trained subjects. Twenty adult men were assigned to 1 of the
following groups: untrained (UT, N = 9) and resistance-trained (RT, N = 11)
groups. The subjects performed six 1 repetition maximum (1RM) load tests of the
following exercises: horizontal bench press, lat pull-downs, bicep curls, and
45° leg press. The results achieved in the last two 1RM tests were used for
statistical analyses. A passive static stretching program was incorporated
before the sixth 1RM test. The body fat content was significantly higher in the
UT group compared with the RT group (p < 0.0001). Moreover,
the RT group showed significantly higher proportion of lean body mass compared
with the UT group (p < 0.0001). Maximum muscle strength on
all 4 exercises was significantly reduced in both groups after stretching (p <
0.01). Furthermore, the magnitude of muscle strength reduction was similar for
the UT and the RT groups. The exception was for barbell curls, in which the
muscle strength depression was significantly higher in the UT group compared
with the RT group (p < 0.0001). In conclusion, the passive
static stretching program was detrimental to upper- and lower-body maximal
muscle strength performance in several body segments. The negative effects of
stretching were similar for subjects participating in resistance training
regimens.

4 Easy Principles For Injury Prevention
This blog post is dedicated to injury prevention. After finishing the book Results Fitness, 2012 written by a variety of health professionals I will focus on the last chapter by Amy Wunsh, a physical therapist at Results Fitness. The book is a great read by the way with different effective strategies on how to get better results related to nutrition and exercise.
The 4 principles to injury prevention:
1. The source of your pain is not always the driver/ cause of your problem. Sometimes pain located at the shoulder derives from the neck. In addition, knee or shooting pain down the leg pain can arise from the lower back. Also, pain at mid- back region might come from visceral organs. Every joint in the body is connected to each other from the ankle joint up to your head. A postural assessment will reveal if any compensations take place.
2. Your body needs maintenance every now and then and you are responsible to take care of it. Prevention through exercise, physiotherapy or any type of recovery strategies such as nutrition, sleep, soft tissue massage or cold immersion are some effective elements. It's a similar analogy to your car maintenance.
3. If there is pain or any other dysfunction in the body, please do not ignore it. You must always take action. If one practitioner does not find out the source of the pain or dysfunction, it is time to look somewhere else. If in case you do not see any improvements in 3-5 therapy sessions then you should seek for another medical opinion, and
4. Consistency is key. Make sure you eliminate the things that make you feel bad or cause you pain and make sure you continue doing the things that make you feel better. This is associated with posture corrections or any type of prevention exercise program that you are following after any type of dysfunction.
It's that simple!

Reviewing literature on using water immersion for recovery
Bleakley, C. M., & Davison,
G. W. (2010). What is the biochemical and physiological rationale for using
cold-water immersion in sports recovery? A systematic review. British journal
of sports medicine, 44(3), 179-187.
ABSTRACT
Cold-water immersion (CWI) is a popular recovery
intervention after exercise. The scientific rationale
is
not clear, and there are no clear guidelines for its
use.
The aim of this review was to study the physiological
and biochemical effect of short periods of CWI. A
computer-based literature search, citation tracking
and
related articles searches were undertaken. Primary
research studies using healthy human participants,
immersed in cold water (<15 5="" durations="" for="" min="">15>
or less were included. Data were extracted on
body temperature, cardiovascular, respiratory and
biochemical response. 16 studies were included.
Sample size was restricted, and there was a large
degree of study heterogeneity. CWI was associated
with an increase in heart rate, blood pressure,
respiratory minute volume and metabolism. Decreases
in end tidal carbon dioxide partial pressure and a
decrease in cerebral blood fl ow were also reported.
There was evidence of increases in peripheral
catecholamine concentration, oxidative stress and a
possible increase in free-radical-species formation.
The
magnitude of these responses may be attenuated with
acclimatisation. CWI induces significant physiological
and biochemical changes to the body. Much of this
evidence is derived from full body immersions using
resting healthy participants. The physiological and
biochemical rationale for using short periods of CWI
in
sports recovery still remains unclear.
Pournot, H., Bieuzen, F.,
Duffield, R., Lepretre, P. M., Cozzolino, C., & Hausswirth, C. (2011).
Short term effects of various water immersions on recovery from exhaustive
intermittent exercise. European journal of applied physiology, 111(7),
1287-1295.
Abstract
In order to investigate the effctiveness of
diVerent techniques of water immersion recovery on
maximal strength, power and the post-exercise inflammatory
response in elite athletes, 41 highly trained
(Football, Rugby, Volleyball) male subjects (age =
21.5 §
4.6 years, mass = 73.1 § 9.7 kg and height = 176.7 §
9.7 cm) performed 20 min of exhaustive, intermittent
exercise followed by a 15 min recovery intervention.
The recovery intervention consisted of diVerent water
immersion techniques, including: temperate water
immersion (36°C; TWI), cold water immersion (10°C;
CWI), contrast water temperature (10–42°C; CWT) and
a passive recovery (PAS). Performances during a
maximal
30-s rowing test (P30 s), a maximal vertical
countermovement
jump (CMJ) and a maximal isometric voluntary
contraction (MVC) of the knee extensor muscles were
measured at rest (Pre-exercise), immediately after the
exercise (Post-exercise), 1 h after (Post 1 h) and 24
h
later (Post 24 h). Leukocyte proWle and venous blood
markers of muscle damage (creatine kinase (CK) and
lactate dehydrogenase (LDH)) were also measured
Preexercise,
Post 1 h and Post 24 h. A significant time effect
was observed to indicate a reduction in performance
(Pre-exercise vs. Post-exercise) following the
exercise
bout in all conditions (P < 0.05). Indeed, at 1 h
post
exercise, a significant improvement in MVC and P30 s
was respectively observed in the CWI and CWT groups
compared to pre-exercise. Further, for the CWI group,
this result was associated with a comparative blunting
of
the rise in total number of leucocytes at 1 h post and
of
plasma concentration of CK at 24 h post. The results
indicate that the practice of cold water immersion and
contrast water therapy are more effective immersion
modalities to promote a faster acute recovery of
maximal
anaerobic performances (MVC and 30[1]
all-out
respectively) after an intermittent exhaustive
exercise.
These results may be explained by the suppression of
plasma concentrations of markers of inflammation
and damage, suggesting reduced passive leakage from
disrupted skeletal muscle, which may result in the
increase in force production during ensuing bouts of
exercise.

C., Wallman, K., & Beilby, J. (2009). Effect of water immersion methods on
post-exercise recovery from simulated team sport exercise. Journal of Science
and Medicine in Sport, 12(3), 417-421.
Abstract
This study aimed to compare the efficacy of hot/cold
contrast water immersion (CWI), cold-water immersion (COLD) and no recovery treatment
(control) as post-exercise recovery methods following exhaustive simulated team
sports exercise. Repeated sprint ability, strength, muscle soreness and
inflammatory markers were measured across the 48-h post-exercise period. Eleven
male team-sport athletes completed three 3-day testing trials, each separated
by 2 weeks. On day 1, baseline measures of performance (10m×20m sprints and
isometric strength of quadriceps, hamstrings and hip flexors) were recorded.
Participants then performed 80 min of simulated team sports exercise followed
by a 20-m shuttle run test to exhaustion. Upon completion of the exercise, and
24 h later, participants performed one of the post-exercise recovery procedures
for 15 min. At 48 h post-exercise, the performance tests were repeated. Blood
samples and muscle soreness ratings were taken before and immediately after
post-exercise, and at 24 h and 48 h post-exercise. In comparison to the control
and CWI treatments, COLD resulted in significantly lower (p < 0.05) muscle
soreness ratings, as well as in reduced decrements to isometric leg extension
and flexion strength in the 48-h post-exercise period. COLD also facilitated a
more rapid return to baseline repeated sprint performances. The only benefit of
CWI over control was a significant reduction in muscle soreness 24 h
post-exercise. This study demonstrated that COLD following exhaustive simulated
team sports exercise offers greater recovery benefits than CWI or control
treatments.

ABSTRACT
Higgins, TR, Heazlewood, IT, and Climstein, M. A
random control
trial of contrast baths and ice baths for recovery
during
competition in U/20 rugby union. J Strength Cond Res
25(4):
1046–1051, 2011—Players in team sports must recover in
a relatively short period of time to perform at
optimal levels. To
enhance recovery, cryotherapy is widely used. To date,
there are
limited scientific data to support the use of
cryotherapy
for recovery. Players (n = 26) from a premier rugby
club
volunteered to participate in a random control trial
(RCT) using
contrast baths, ice baths, and no recovery.
Statistical analysis,
between group and within group, with repeated measures
was
conducted along with determination of effect sizes in
2 field tests.
Pre and postfield tests including a 300-m test and a
phosphate
decrement test and subjective reports were conducted
during
the RCT. No significant difference was identified
between base
tests and retests in the phosphate decrement test or
the 300-m
tests. Effect size calculations identified a medium to
large effect
(d = 0.72) for 300-m tests for contrast baths against
control.
Trivial effects were identified for ice baths (d =
0.17) in the 300-m
test against control. Effect size calculations in the
phosphate
decrement test showed a trivial effect (d = 0.18)
contrast baths
and a negative effect (d = 20.62) for ice baths.
Treatment–
treatment analysis identified a large effect for
contrast baths
(d = 0.99) in the phosphate decrement test and a
medium effect
for contrast baths (d = 0.53) in the 300-m test.
Effect scores
across contrast baths, ice baths, and passive recovery
along with
subjective reports indicate a trend toward contrast
baths
benefiting recovery in rugby. The continued use of
5-minute
ice baths for recovery should be reconsidered based on
this
research because trends suggest a detrimental effect.

Transverse abdominis exercise in supine lying
STARTING
POSITION: Lie on
your back with knees bent
Keep
your spine in neutral throughout movement.
Place
fingers just medial of hip bones
Draw the
lower part of you belly down towards the bed.
Make
sure you continue to breathe normally throughout exercise whilst maintaining a
steady contraction.
Hold
each contraction for 15 seconds
10-15
repetitions
2-3
times a day
Designed by Eleanor Clare Peebles
This is an exercise for a stable spine. It is proven in research that the transverse abdominal muscle (ring shape- the deeper of the abdominal muscles ) is usually not firing in back pain patients, yet pain can be developed if the spine is not stable interfering with normal back biomechanics. If you do not have lower back pain, you can use this exercise for prevention.

Mothers affair article regarding Youth Training (October issue) in Greek
Παιδιά και Γυμναστική από κ. Αντρέα Πρέζα, ιδρυτή του YOUTH MOVEMENT PERFORMANCE, Λευκωσία.
Όπως
όλοι γνωρίζουμε ο τρόπος ζωής και οι ασχολίες των ανθρώπων έχουν αλλάξει
δραματικά τα τελευταία 5- 10 χρόνια, αλλάζοντας ταυτόχρονα και τις ασχολίες και τις συνήθειες των παιδιών. Συνέπεια
των αλλαγών αυτών, αποτελούν η μη εκγύμναση των παιδιών και η συχνή εμφάνιση
της παιδικής παχυσαρκίας.
Η
παιδική παχυσαρκία, σύμφωνα με έρευνες, βρίσκεται σε ψηλά επίπεδα θέτοντας σε
κίνδυνο την υγεία των παιδιών. Η εμφάνισή
της οφείλεται σε δύο κυρίους λόγους: στην κακή διατροφή και στο μειωμένο χρόνο
ή απουσία γυμναστικής. Στο πάρων στάδιο,
σε αυτό το άρθρο, θα επικεντρωθούμε στο θέμα της γυμναστικής. Μερικά εύλογα ερωτήματα που αφορούν στην
γυμναστική για παιδιά είναι: Σε ποια ηλικία είναι καλά να αρχίσει να γυμνάζεται
ένα παιδί; Ποιο είδος γυμναστικής είναι
το καταλληλότερο και ποιος είναι ο στόχος του γυμναζόμενου παιδιού σε κάθε
ηλικία; Η εξειδίκευση σε κάποιο άθλημα
σε μικρή ηλικία έχει μήπως αρνητικά αποτελέσματα;
Ένα
παιδί μπορεί να αρχίσει να γυμνάζεται στην ηλικία μόλις των 2 ετών. Πρέπει να σημειωθεί πως στην περίπτωση που
ένα παιδί είναι παχύσαρκο,
παρατηρούνται βασικές αναπτυξιακές
καθυστερήσεις στις ηλικίες των 4-5
χρονών λόγω μειωμένων ευκαιριών και μειωμένων κίνητρων. Ο κύριος αρχικός στόχος
εκγύμνασης των παχύσαρκων παιδιών είναι η εύρεση μεθοδολογιών γυμναστικής που αρέσουν σε αυτά και η
επικέντρωσή τους σε αυτές, ιδιαίτερα στα αρχικά στάδια.
O κάθε γονιός πρέπει να γνωρίζει πως η
γυμναστική για παιδιά μπορεί να διαχωριστεί σε 4 κατηγορίες/ ηλικίες σύμφωνα με
τις αναπτυξιακές τους ικανότητες και ανάγκες:
1. Ηλικίες 2-5 χρονών. Ο στόχος σε αυτή την κατηγορία είναι να
αρχίσουν τα παιδιά να μαθαίνουν και να εκτελούν τις βασικές κινήσεις του σώματος με το σωστό τρόπο όπως
τρέξιμο, ρίψη, χοροπήδημα και άλλες κινητικές
δεξιότητες. Μέσω της εξειδικευμένης γυμναστικής αναπτύσσουν επίσης τη
λεπτή κινητικότητα, τον οπτικοκινητικό συντονισμό και τον επιδέξιο χειρισμό αντικειμένων.
Πρέπει να σημειωθεί πως επιστημονικές μελέτες έχουν αναφέρει πως η γυμναστική
σε αυτή την ηλικία είναι απαραίτητη γιατί μπορεί να καθορίσει την υγεία των
παιδιών σε μεταγενέστερο στάδιο. Το ελεύθερο παιχνίδι αποκλειστικά δεν είναι
αρκετό για την πλήρη ανάπτυξη του παιδιού καθώς δεν περιλαμβάνονται οι
προαναφερθέντες δραστηριότητες με στοχευμένο, προγραμματισμένο και
εξειδικευμένο τρόπο.
2. Ηλικίες 6-9 χρονών. Ο πρωταρχικός στόχος σε αυτή την κατηγορία
είναι επίσης η μάθηση και εκτέλεση θεμελιωδών κινήσεων όπως στις ηλικίες
2-5. Η φιλοσοφία είναι οργανωμένο παιχνίδι με στόχους. Η
συμμετοχή και ο ενθουσιασμός είναι τα δυο απαραίτητα στοιχεία του προγράμματος
γυμναστικής σε αυτή την κατηγορία. Η
ικανότητα και ο χρόνος συγκέντρωσης των παιδιών σε αυτές τις ηλικίες είναι
μειωμένη, γι΄ αυτό το λόγο οι πολλές και σύνθετες οδηγίες είναι καλύτερα να
αποφεύγονται.
3. Ηλικίες
10-13 χρονών. Η φιλοσοφία σε αυτή
την κατηγορία είναι η εξερεύνηση μέσω της
γυμναστικής. Οι αυξημένες και ήδη αποκτημένες δεξιότητες, καθώς και η ωρίμανση,
σε αυτές τις ηλικίες είναι τα χαρακτηριστικά που μπορούν να συνδεθούν άμεσα με
την αθλητική τους ικανότητα, η οποία χρειάζεται βελτίωση με την πάροδο του
χρόνου.
Η επιλογή ασκήσεων, δίνοντας απλές οδηγίες και
χρησιμοποιώντας κίνητρα, αποτελούν τη φιλοσοφία της προπόνησης. Η ομαδικότητα πρέπει να καλλιεργείται μέσω
της προπόνησης, ενώ η γυμναστική σε ατομικό επίπεδο είναι καλυτέρα να
αποφεύγεται. Σε αυτή την κατηγορία και
συγκεκριμένα από την ηλικία των 12 χρονών και άνω, η γυμναστική μέσω μυϊκής
ενδυνάμωσης μπορεί να αρχίσει.
4.
Ηλικίες
14 και άνω. Σε αυτή τη κατηγορία η
γυμναστική έχει πολλές ομοιότητες με τη γυμναστική ενός ενήλικα. Στους εφήβους
παρατηρείται αυξημένη μυϊκή μάζα και κινητική ανάπτυξη. Η φιλοσοφία πίσω από αυτό το στάδιο είναι γυμναστική μέσω εφαρμογής. Συγκεκριμένα, η γυμναστική είναι περισσότερο
πολύπλοκη, πραγματοποιείται σε μεγαλύτερη ένταση, και η εξατομίκευση μπορεί να είναι
εφικτή. Η ευκινησία, η σταθεροποίηση και η ευλυγισία των αρθρώσεων είναι
σημαντικά στοιχεία τα οποία καθορίζουν την αθλητική επίδοση των εφήβων. Στην
περίπτωση όπου οι έφηβοι δεν έχουν τα προαναφερθέντα στοιχεία, κρίνεται
απαραίτητο να τα βελτιώσουν μέσω της γυμναστικής.
Κάτι
το οποίο παρατηρείται έντονα, είναι η εξειδίκευση μικρών παιδιών σε κάποιο
άθλημα και στηρίζεται στην ίδια φιλοσοφία με τη φιλοσοφία εκγύμνασης ενός
ενήλικα, χωρίς όμως να λαμβάνονται υπόψη οι αναπτυξιακές αλλαγές του παιδιού. Ένα
παιδί δεν μπορεί να γυμναστεί ως ‘μικρός ενήλικας’ και η γυμναστική μεταξύ ενός
ενήλικα και ενός παιδιού διαφέρουν λόγων των αναπτυξιακών τους διαφορών που διαχωρίζονται
σε νευρολογικές, μυϊκές, σκελετικές, ορμονικές. Από τη μία πλευρά, η
εξειδίκευσή στο ποδόσφαιρο, τένις, κολύμβηση και άλλα αθλήματα, μπορεί να
ενισχύσει την αθλητική απόδοση, κάτι το οποίο θα παρατηρηθεί στα αρχικά στάδια.
Από την άλλη πλευρά, σύμφωνα πάντοτε με επιστημονικές έρευνες, ο βαθμός ψυχολογικής
πίεσης και κόπωσης, σωματικής εξουθένωσης και ο αυξημένος κίνδυνος τραυματισμών
έχει περισσότερη βαρύτητα και πιθανόν να φέρει αντίθετα αποτελέσματα.
Η
φιλοσοφία εκγύμνασης ενός παιδιού πρέπει να στοχεύει στην Μακροχρόνια Αθλητική
Ανάπτυξη (ΜΑΑ) και να έχει ως κίνητρο την βελτίωση της φυσικής κατάστασης και
όχι της επίδοσης. Η ΜΑΑ στηρίζεται αρχικά στην εξοικείωση των παιδιών με την
γυμναστική σταδιακά, όπως αναφέραμε
πιο πάνω με τις κατηγορίες (ηλικίες 2-5, 6-9, 10-13, 14+). Αφού προηγηθεί η
ΜΑΑ, τότε ένας έφηβος έχει τις βάσεις και είναι πλέον σε θέση να ανταποκριθεί στην
εξειδίκευση σε ένα άθλημα. Επίσης, η ΜΑΑ βελτιώνει την αθλητική εμπειρία και
μειώνει τους τραυματισμούς.
Όπως
έχει προαναφερθεί, τα παιδιά είναι αναγκαίο να γυμνάζονται από μικρή ηλικία
(από 2 ετών), έτσι ώστε να υιοθετήσουν ένα υγιή τρόπο ζωής και να βελτιώσουν
την ποιότητα της ζωής τους. Συνοψίζοντας, η κάθε ηλικιακή ομάδα έχει τον κύριο
στόχο της και στηρίζεται στα αναπτυξιακά δεδομένα του κάθε παιδιού. Η εξειδίκευση
σε κάποιο άθλημα είναι καλύτερα να πραγματοποιείται σε ηλικίες άνω των 15 χρονών,
αφού έχουν εξοικειωθεί με διάφορα αθλήματα και αφού οι θεμελιώδης κινήσεις του σώματος έχουν καλλιεργηθεί.
Η εκγύμναση των παιδιών είναι προτιμότερο να στηρίζεται στην Μακροχρόνια Αθλητική
Ανάπτυξη.

Cooking tip for Beans
Beans were the Roman gladiator's main source of protein. As for the Greeks, beans were considered as a symbol of democracy. The benefits of beans in your diet are endless, yet in today's post we are going to talk about bean cooking. As suggested from Hofmekler's book 'The warrior diet'' (an alternative diet methodology), to eliminate gas formation, bloating, and water retention the correct cooking bean regime is:
1. Triple rinsing
2. Soak in water overnight
3. Triple rinsing again, and at the end
4. Peel and remove the skin- all before cooking
Make sure you kill those healthy beans! I'm out.......
