“…Thus, we used protocols that were time-economical and that had been previously used in recent studies for the assessment of muscle-skeletal function in older people [15]. All testing procedures were applied before the experimental period (T1) and after 16 weeks of training (T2).…”

“…The subject was instructed to perform from the starting position a purely concentric action maintaining the shoulders in a 90 • abducted position following 3 to 4 trials until the subject was unable to reach the fully extended position of the arms. The last acceptable extension with the highest possible load was determined as 1 RM BP [15].…”

“…A trigonometric carpet (Ergojump Digitime 1000; Digitest, Jyvaskyla, Finland) was used to assess maximum height in counter-movement vertical jump (CMJ) [15]. Each subject started from an erect standing position and the end of the concentric phase corresponded to a full leg extension (180 • ).…”

KEYWORDSExercise; Bone formation marker; Post-menopausal women SummaryObjectives. -Exercise plays an important role in maximizing and subsequent reduction of the maximum rates of bone loss. The purpose of this study was to determine whether 16 weeks of combined exercise in postmenopausal would affect bone metabolism. Results. -After the training period, postmenopausal significantly (P < 0.05) increase their muscle functionality (14% to 26.5%). Levels of NTX were not affected but there was a significant increase in bone synthesis (ALP: 12.5% to 15.9%), while there is no change in bone resorption. Combined training appears to be useful in improving total muscular performance and potentially in bone density. © 2016 Elsevier Masson SAS. All rights reserved. Résultats. -Après la période de formation, les femmes post-ménopausées ont vu la fonctionnalité des muscles augmenter significativement (p < 0,05) (14-26,5 %). Les niveaux de NTX n'ont pas été affectés, mais il y avait une augmentation significative de la synthèse osseuse (ALP : 12,5-15,9 %), alors qu'il n'y a aucun changement dans la réabsorption osseuse. La formation combinée semble être utile dans l'amélioration de la performance musculaire totale et, potentiellement, dans l'augmentation de la densité osseuse. MOTS CLÉS

“…12 weeks of muscle power program was subjected to elderly women with hyperglycemia, and the exercise group showed significant increase in the physical performance ability test (SPPB) and muscular strength test, which proved that exercise effected in the change of physical function [4] and increasing the power developed in the competitive skill [5]. The results of the study reveal that there is a significant difference in the shoulder strength of specific drills with elastic band training group between the pre-test and post-test, test.…”

To achieve the purpose of the present study thirty subjects were selected from Ramakrishna Mission Vidyalaya Maruthi College of Physical Education, Periyanaickenpalayam, Coimbatore, Tamil Nadu. Their age ranged from 21 to 23 years. They were assigned to two group namely experimental group-I with fifteen college men who were given specific drills with elastic band training exercises for 12 weeks 5 days a week and from 5 pm to 6 pm and other group-II with fifteen boys acted as control group. The experimental group was tested on explosive power and shoulder strength. The selected criterion variables explosive power was tested with standing broad jump test and shoulder strength was tested with push ups. After twelve weeks specific drills with elastic band training exercises post test data were collected and treated with ANCOVA. The level of confidence was fixed at 0.05. The study results showed that the experimental group had significantly altered selected variables explosive power and shoulder strength which was due to the influence of specific drills with elastic band training exercises training programme. The control group did not improve on selected criterion variables.

“…Two systematic reviews [1,5] reported that a slower walking speed is predictive of mobility limitations and a higher subsequent risk of fracture, institutionalization and mortality [6,7]. In older populations, functional capacity declines with advancing age, especially in older women [8], which increases the importance of rehabilitation and prevention programs to increase strength, mobility and balance confidence.…”

BackgroundWe studied the influence of the ACE I/D and ACTN3 R577X polymorphisms (single or combined) on lower-extremity function in older women in response to high-speed power training.MethodsOne hundred and thirty-nine healthy older Caucasian women participated in this study (age: 65.5 ± 8.2 years, body mass: 67.0 ± 10.0 kg and height: 1.57 ± 0.06 m). Walking speed (S10) performance and functional capacity assessed by the “get-up and go” (GUG) mobility test were measured at baseline (T1) and after a consecutive 12-week period of high-speed power training (40-75% of one repetition maximum in arm and leg extensor exercises; 3 sets 4–12 reps, and two power exercises for upper and lower extremity). Genomic DNA was extracted from blood samples, and genotyping analyses were performed by PCR methods. Genotype distributions between groups were compared by Chi-Square test and the gains in physical performance were analyzed by two-way, repeated-measures ANOVA.ResultsThere were no significant differences between genotype groups in men or women for adjusted baseline phenotypes (P > 0.05). ACE I/D and ACTN3 polymorphisms showed a significant interaction genotype-training only in S10 (P = 0.012 and P = 0.044, respectively) and not in the GUG test (P = 0.311 and P = 0.477, respectively). Analyses of the combined effects between genotypes showed no other significant differences in all phenotypes (P < 0.05) at baseline. However, in response to high-speed power training, a significant interaction on walking speed (P = 0.048) was observed between the “power” (ACTN3 RR + RX & ACE DD) versus “non-power” muscularity-oriented genotypes (ACTN3 XX & ACE II + ID)].ConclusionsThus, ACE I/D and ACTN3 R577X polymorphisms are likely candidates in the modulation of exercise-related gait speed phenotype in older women but not a significant influence in mobility traits.
