PURPOSE Excessive, chronic whole-body vibration (WBV) has a number of negative side effects on the human body, including disorders of the skeletal, digestive, reproductive, visual, and vestibular systems. Whole-body vibration training (WBVT) is intentional exposure to WBV to increase leg muscle strength, bone mineral density, health-related quality of life, and decrease back pain. The purpose o...

INTRODUCTION Centrifuge-induced artificial gravity (AG) with exercise is a promising comprehensive countermeasure against the physiological de-conditioning that results from exposure to weightlessness. However, body movements onboard a rotating centrifuge are affected by both the gravity gradient and Coriolis accelerations. The effect of centrifugation on squat exercise biomechanics was investi...

The purpose of this investigation was to determine the effect of different lifting cadences on the ground reaction force (GRF) during the squat exercise. Squats performed with greater acceleration will produce greater inertial forces; however, it is not well understood how different squat cadences affect GRF. The hypotheses were that faster squat cadences would result in greater peak GRF and th...

This paper presents the design of crack finding robot for finding cracks in railway tracks. Here PIC16F877A microcontroller is interfaced with Robot, Zigbee, GPS, LCD and IR sensors. The IR sensors are used to find crack in the railway track, and then GPS is used to find the location. If the microcontroller detects the crack, it immediately gets the location information using GPS and sends that...

The objective of this study was to compare (i) effects a flywheel and free-weight resistance training program; (ii) performing lateral frontal split squats as part flywheel-resistance program on jumping performance, the 5–0–5 change direction test time, one-repetition maximum (1RM) back squat in soccer players. Twenty-four male amateur players participated were randomly equally assigned one thr...

The strength and stability of the knee plays an integral role in athletics and activities of daily living. A better understanding of knee joint biomechanics while performing variations of the squat would be useful in rehabilitation and exercise prescription. We quantified and compared tibiofemoral joint kinetics as well as muscle activity while executing front and back squats. Because of the in...

Aim: To verify the effects of a 2-week high-intensity interval training (HIIT) on physical performance in young female athletes. Methods: rugby players (n = 13; 15.92 ± 0.76 years old) participated an 8-session HIIT supervised through online video calls for two weeks. They were evaluated pre- and post-HIIT 3-min burpees, 1-min sit-ups, maximum push-ups, squats. Perceptions related to protocols ...

Background and aims: Fatigue is associated with longitudinal ratings of health in patients with chronic obstructive pulmonary disease (COPD). Although the degree of airflow obstruction is often used to grade disease severity in patients with COPD, multidimensional grading systems have recently been developed. The aim of this study was to investigate the relationship between perceived and actual...
