Mejora de los parámetros espacio temporales de pasos, actividad muscular de las extremidades inferiores y registros de marchadores después de ejercicios especiales de 12 semanas usando audición rítmica

This study aims to know the effect of 12-weeks of special exercises using rhythmic auditory to improve spatio-temporal stride parameters (STSP), lower limb muscles activity (LLMA), and 10000m racewalking time (RT). The parameters of STSP are stride length (SL), step cadence (SC), and center-of-mass velocity (CMV). The research sample included twelve racewalkers, and they were divided into two groups (control group and experimental group, six in each). STSP was measured using a Sony camera at a speed of 50 frames/sec for analyzing 25-samples for each racewalker in the 10000m racewalking. LLMA was measured using EMG. In addition, we applied the 10000m test to measure RT. Rhythmic auditory wasused to regulate the step rhythm in seven special exercises and the essential part of the training. The steps rhythm was divided into three levels: the 1st slow auditory rhythm, the 2nd comfortable auditory rhythm, and the 3rd fast auditory rhythm. From our findings, there is a significant difference in the post-test for SC, CMV, LLMA, and RT,favoring the experimental group,where P.04.05. In addition, there is a significant improvement between groups favoring the experimental group as ROC=1.62,5.76,7.48,33.9, and 7.03% for SL, SC, CMV, LLMA, and RT respectively. Comparisons showed that the post-test achieved greater mprovement with a large effect in STSP, LLMA, and RT compared to the pre-test that achieved a small effect. Therefore, the rhythmic auditoryin the training has a beneficial role in improving spatio-temporal stride parameters, lower limb muscles activity and racewalkers’ records.El objetivo de este estudio fue investigar el efecto de 12 semanas de ejercicio con audición rítmica en la mejora de los parámetros de zancada espaciotemporal (STSP), actividad muscular de las extremidades inferiors (LLMA) y tiempo de marcha de 10.000 metros (RT). Los parámetros de los pasos espacio-temporales de la zancada son la longitud de la zancada (SL), el ritmo de la zancada (SC) y la velocidad del centro de masa (CMV). La muestra de la investigación estuvo conformada por doce marchadores, quienes fueron divididos en dos grupos (un grupo de control yun grupo experimental, con seis en cada grupo). LosSTSP se midieroncon una cámara Sony a 50 fotogramas/seg para analizar 25 muestras de cada marchador de 10.000 metros. LLMA se midió mediante un electromiograma. Además, aplicamos la prueba de 10.000 m para medir el RT. La audición rítmica se utilizópara regular el ritmo del paso en siete ejercicios especiales y la parte central del entrenamiento. El ritmo de los pasos se dividió en tres niveles: el primer ritmo auditivo lento, el segundo ritmo auditivo cómodo y el tercero ritmo auditivo rápido. De nuestros hallazgos existe una diferencia significativa en el post-test para SC, CMV, LLMA yRT, a favor del grupo experimental, donde P.04 .05. Además, hay una mejora significativa entre los grupos a favordelgrupo experimental:ROC = 1.62, 5.76, 7.48, 33.9 y 7.03 % para SL, SC, CMV, LLMA y RT respectivamente. Las comparaciones mostraron que el post-test logró una mayor mejora con un efecto significativo en STSP, LLMA y RT en comparación con el pre-test que logró un efecto pequeño. Por lo tanto,la audición rítmica en el entrenamiento tiene un papel útil en la mejora de los parámetros de paso espacio-temporales, la actividad muscular de las extremidades inferiores y los registros de la marcha

The Pyramid of Queen Setibhor at South Saqqara

This paper aims to present the preliminary results of the 2021 season of the Djedkare Project mission (DJP), which is dedicated to the exploration and documentation of Djedkare’s royal cemetery at south Saqqara. The main focus of the article is the queen’s pyramid, situated to the north-east of the king’s pyramid and to the north of his funerary temple. The 2018 exploration of the area between the king’s temple and the queen’s pyramid not only revealed the name of the owner, Setibhor, but it also confirmed that the two pyramid complexes were not architecturally connected, as previously presumed, and that further work is needed to clarify the plan of the queen’s monument. In 2021, the investigations focused on the pyramid of the queen; its substructure had never been entered and documented in the modern period. Cleaning the substructure resulted in a detailed documentation of its inner rooms. It used to be accessed through a descending and horizontal corridor and it comprised a burial chamber and a so-called serdab. The innovated layout of Setibhor’s pyramid substructure apparently inspired later queens, who continued to follow this pattern in their monuments during the Sixth Dynasty.This paper aims to present the preliminary results of the 2021 season of the Djedkare Project mission (DJP), which is dedicated to the exploration and documentation of Djedkare’s royal cemetery at south Saqqara.

SurvSec: A New Security Architecture for Reliable Network Recovery from Base Station Failure of Surveillance WSN

AbstractSecuring surveillance wireless sensor networks (WSNs) in hostile environments such as borders, perimeters and battlefields during Base Station (BS) failure is challenging. Surveillance WSNs are highly vulnerable to BS failure. The attackers can render the network useless by only destroying the BS as the needed efforts to destroy the BS is much less than that is needed to destroy the network. This attack scenario will give the attackers the best chance to compromise many legitimate nodes. Previous works have tackled BS failure by deploying a mobile BS or by using multiple BSs. Despite the best electronic countermeasures, intrusion tolerance and anti-traffic analysis strategies to protect the BSs, an adversary still can destroy them. This paper proposes a novel security architecture called Surveillance Security (SurvSec) for reliable network recovery from single BS failure of surveillance WSN with single BS. SurvSec relies on a set of sensor nodes serve as Security Managers for management and storage of the security related data of all sensor nodes. SurvSec security architecture provides methodologies for choosing and changing the security managers of the surveillance WSN. SurvSec has three components: (1) Sensor nodes serve as Security Managers, (2) Data Storage System, (3) Data Recovery System. Furthermore, both the frame format of the stored data is carefully built and the security threats are encoded to allow minimum overheads for SurvSec security architecture. In this paper, we provide detailed specifications of SurvSec security architecture. We evaluate our designed security architecture for reliable network recovery from BS failure. Our evaluation shows that the proposed new security architecture can meet all the desired specifications and our analysis shows that the provided Security Managers are capable of network recovery from BS failure

Effects of high-intensity interval training using “Tabata protocol” on respiratory parameters, special endurance, and 800-m runners’ performance

This study aims to investigate the effects of high-intensity interval training using the Tabata protocol on respiratory parameters, special endurance (cardiorespiratory endurance, anaerobic speed endurance, and strength endurance), and 800-m runners’ performance. A total of 20 well-trained males in the 800-m running were assigned into two equal groups, the experimental group, and the control group, and all mentioned variables were measured before and after 8 weeks of the intervention. Respiratory parameters were assessed by using a BTL-08 Spirometer device. Cooper’s 12-min running test was used to measure cardiorespiratory endurance. A repeated sprint test (6x30-m) was used to assess anaerobic speed endurance. Tests for strength endurance consisted of repeated squat and sit-ups tests. The main findings indicate that the experimental group showed greater improvement in respiratory parameters, cardiorespiratory endurance, anaerobic speed endurance, strength endurance, and 800-m runners’ performance than the control group; where (ES≈ 0.42:0.65, 0.34, 0.31:0.76, 0.48:0.63 and 0.72) (p .05). Our results suggest that runners after Tabata protocol interventions can obtain better pulmonary function, endurance, and event time benefits with more efficient performance and time-efficient manner compared with traditional training

Suspension training versus free weight training: effects on explosive power, dynamic balance, and discus throwers performance

Background and Study Aim. This paper aims to compare the effects of two types of resistance training programs (suspension training and free weight training) on the explosive power, dynamic balance, and discus throwers performance. Material and Methods. Twenty-four male discus throwers (with an average age: 19.17 ± 0.99 years; body mass: 99.87 ± 3.63 kg; height: 177.23 ± 3.16 cm) were assigned into three groups (eight subjects in each group); suspension training (STG), free weight training (FWTG) and control (CG). For eight weeks, subjects underwent training consisting of three sessions a week. Prior to and after the training period, explosive power, dynamic balance, and discus throwing distance variables were measured. The explosive power was measured using the medicine ball throw (SLJT) and standing long jump (MBTT) tests. The dynamic balance was measured using the Y excursion balance test (YBT). The discus throwing distance was measured according to the IAAF rules (DTT). Results. The results showed that both experimental groups had a significant effect on MBTT, SLJT, and DTT compared to the control group. There was a significant difference in YBT favoring STG when compared to the FWTG and CG, and also, favoring FWTG when compared to CG in the three directions (anterior, posterolateral, and posteromedial). All three groups improved the tests from pre- to post-test. Conclusions. We can conclude that suspension training and free weight training have created almost the same improvements in explosive power. Also, suspension training was more effective than free weight training for improving dynamic balance
