The purpose of the study was to compare the force outputs achieved during a squat exercise using a rotational inertia device in stable versus unstable conditions with different loads and in concentric and eccentric phases. Thirteen male athletes (mean ± SD: age 23.7 ± 3.0 years, height 1.80 ± 0.08 m, body mass 77.4 ± 7.9 kg) were assessed while squatting, performing one set of three repetitions...

AIM Cardiovascular autonomic neuropathy (CAN) and pulsatile stress are considered to be independent cardiovascular risk factors. This study compared haemodynamic changes during an active orthostatic test in adult patients with type 1 diabetes (T1DM), using low versus high RR E/I ratios as a marker of CAN. METHODS A total of 20 T1DM patients with low RR E/I ratios were compared with 20 T1DM pa...

The purpose of this study was to compare oxidative modification of blood proteins, lipids, DNA, and glutathione in the 24 hours following aerobic and anaerobic exercise using similar muscle groups. Ten cross-trained men (24.3 +/- 3.8 years, [mean +/- SEM]) performed in random order 30 minutes of continuous cycling at 70% of Vo(2)max and intermittent dumbbell squatting at 70% of 1 repetition max...

evaluation of functional disability using proper instruments, like health assessment questionnaire (haq) in patients with rheumatoid arthritis (ra), is necessary not only for quality of life assessment, but also as a useful marker for disease activity. haq has been translated into many languages. to validate the persian version of stanford haq. persian version of the haq (pe-haq) with culturall...

This paper investigates a method through which a human-size humanoid robot can fall over backwards safely. Squatting-extending motion of legs reduce impact of falling and shock-absorbing parts of the robot keep the force at a permissible range. The robot could stand up itself again after falling.

Construction workers regularly perform tasks that require kneeling, crawling, and squatting. Working in awkward kneeling postures for prolonged time periods can lead to knee pain, injuries, osteoarthritis. In this article, we present lightweight, wearable sensing, assistive devices construction during squatting tasks. Analysis of on level sloped surfaces (0 <sup xmlns:mml="http://www.w3.org/199...

T he squat is widely used as a staple exercise in resistance training programs. It is used by athletic and recreational populations alike to enhance both strength and hypertrophy of the lower-body musculature and improve functional performance (17). However, considerable controversy exists as to optimal squat depth, particularly as to whether deep squatting increases the risk of injury to the k...
