Background. Physical activity programs in nursing homes typically consist of seated, range motion (ROM) exercises, regardless resident abilities. The Functional Fitness for Long-Term Care (FFLTC) Program was designed not only to maintain ROM, but also improve strength, balance, flexibility, mobility, and function. In addition, it tailored meet the needs both high low mobility residents. Methods. feasibility efficacy FFLTC were evaluated with 68 residents (mean age 80) from five institutions....

The purpose of this study was 1) to test the hypothesis that ventilation and arterial oxygen saturation (Sa O 2 ) during acute hypoxia may increase intermittent remain elevated for a week without hypoxic exposure 2) clarify whether changes in Sa exercise are correlated with change chemosensitivity. Six subjects were exposed simulated altitude 4,500 m 7 days (1 h/day). Oxygen uptake (V˙o ), expired minute (V˙e), measured maximal submaximal at 432 Torr before (Pre), after (Post), again sea...

We aimed to assess the effects of interaction between several breathing patterns and postures on abdominal muscle activation intra-abdominal pressure (IAP). This comparative cross-sectional study enrolled fourteen healthy university students majoring in sports science and/or physical education. They performed four active tasks: quiet nasal (Q-Bre), deep (Deep-Bre), completely forced expiration (Forced-Expi), exertional inhalation with muscles isometric contraction (Exertion-Inspi) elbow-toe...

The present study was performed to clarify the effects of intermittent exposure an altitude 4,500 m with endurance training and detraining on ventilatory chemosensitivity. Seven subjects (sea-level group) trained at sea level 70% maximal oxygen uptake (VO2 max) for 30 min/day, 5 days/wk 2 wk, whereas other seven (altitude same relative intensity (70% VO2 in a hypobaric chamber. max, hypoxic response (HVR), hypercapnic response, as index central chemosensitivity (HCVR) peripheral (HCVRSB),...

This study examined circulatory and metabolic changes in a working muscle during crank cycle pedaling exercise with near-infrared spectroscopy (NIRS).NIRS measurements sampled under stable cadence conditions incremental were reordered according to the angles whose signals obtained eight male subjects.The blood volume demonstrated pattern change that corresponded pedal force electrical activity for thrust. The top bottom peaks at work intensities of 180 W 220 always preceded (88 +/- 32 92 23...

The purpose of the present study was to examine effects ankle taping and bracing based on peroneal reflex in hypermobile normal joints with without history injury. Thirty-six 18 collegiate American football athletes previous injury were studied. angle talar tilt (TT) measured by stress radiograph for classifying (TT ≤ 5°) or > ankles. They tested taping, bracing, any supports as a control. latency peroneus longus muscle sudden inversion 25 degrees using surface EMG signals. results show no...

The aim of the present study was to elucidate (1) cardiovascular adaptations and response hypoxic stimuli during short-term intermittent hypoxia (2) whether change in is correlated ventilatory chemosensitivity. Fourteen subjects were decompressed a chamber 432 torr, simulating an altitude 4500 m, over period 30 min maintained at that pressure for 1 h daily 7 days. Ventilatory (ΔVdotI/ΔSaO2; SaO2 arterial oxygen saturation), systolic diastolic blood (ΔSBP/ΔSaO2 ΔDBP/ΔSaO2), heart rate...

Abstract Changes in biceps brachii muscle hardness assessed by a push-in meter (PM) and strain elastography (SE) were compared between eccentric (ECC) concentric contractions (CON) of the elbow flexors to test hypothesis that would increase greater after ECC. Ten men performed 5 sets 10 ECC with their non-dominant arms CON dominant using dumbbell corresponding 50% maximum voluntary isometric contraction (MVIC) force at 90º flexion. Before 1–4 days exercise, MVIC force, joint angles,...

The effect of age on mechanomyography (MMG) has not been examined for electrically evoked contractions. Similar to torque, we expected that postactivation potentiation the MMG would differ between young and old subjects. Additionally, under voluntary conditions, compared normalized electromyographic (EMG) signals in relation MMG, unlike EMG, be affected by age. In 10 men, electrical stimulation was delivered before after a 10-s maximal contraction (MVC) assess contractile (twitch torque;...

This study aimed to clarify the activation characteristics of vastus lateralis muscle in front leg during timing correction for a sudden decrease velocity target baseball swings. Eleven male collegiate players performed coincident tasks that comprised constant 8 m/s (unchanged) and from 4 (decreased velocity). Electromyography (EMG) revealed was typically monophasic when responding unchanged conditions. The type swings response decreased condition both biphasic. When biphasic appeared...

Persistent quadriceps weakness after anterior cruciate ligament (ACL) reconstruction is a common hurdle to efficient rehabilitation. Therefore, we evaluated new treatment strategy for athletes with ACL reconstruction. Eleven unilateral performed one set of flywheel Bulgarian split squats exhaustion maximum knee extension 60°, over 16 sessions, on their reconstructed limb. Quadriceps rate force development (RFD) 0-50 ms (RFD0-50 ms), and 0-150 (RFD0-150 voluntary isometric contraction (MVIC),...

This study aimed to investigate the effects of wearing a compression garment (CG) during night sleep on muscle fatigue recovery after high-intensity eccentric and concentric knee extensor exercises. Seventeen male college students participated in 2 experimental sessions under CG non-CG (NCG) conditions. Before or NCG conditions, subjects performed fatiguing protocol consisting 10 sets repetitions maximal isokinetic contractions, with 30-second rest intervals between sets. Immediately before...

Abstract This study investigated the relationship between push-in meter (PM) and ultrasound strain elastography (USE) for biceps brachii (BB) muscle hardness. BB hardness of 21 young men was assessed by PM USE during rest isometric contractions six different intensities (15, 30, 45, 60, 75, 90% maximal voluntary contraction: MVC) at 30°, 60° 90° elbow flexion. Muscle (E) calculated from force–displacement in PM, ratio (SR) an acoustic coupler (elastic modulus: 22.6 kPa) regions interest...

Ishida, S. Mori, M....

For developing and maintaining cardiorespiratory, musculoskeletal, neuromotor fitness in healthy adults, a minimum of 30 min moderate-intensity physical activity or 20 vigorous-intensity per exercise day is recommended. However, many adults are still physically inactive because the lack time facilities, bad weather, other factors. Therefore, it important to develop type that effective for health promotion easy do daily life. An with stairs likely satisfy this aim. Using data from previous...
