Optimisation considerations for the measurement of human muscle power
… ergometer exercise tests are designed to measure power outputs. Most of the tests utilise resistive forces that are based on total-body mass values (TBM). Conceptually, selecting an optimal resistive force based on total-body mass may not be the best approach. Resistive forces that reflect the …

The validation of muscle power output measures in lower and upper body resistance exercises
… of measurements of force, velocity and power measured simultaneously during upper and lower body resistance exercises for the following three methods: a) power derived from ground reaction force, i.e. using a force plate (FP), b) power derived from the displacement of the bar, i.e. …

Decreased Peak Muscle Power is Associated with Motor Unit Loss in the Lower Limb of Older Adults
… motor unit (MU) properties and the strength and power of two lower limb muscles in healthy young and old adults. Twelve older adults (mean age, 77 ± 5 yrs) and twelve young adults (mean age, 24 ± 3 yrs) were studied. MU properties of the tibialis anterior (TA) and vastus medialis (VM) muscles …

DOES STRENGTH TRAINING IMPROVE MUSCULOSKELETAL HEALTH AND BODY COMPOSITION IN BLACK MEN WITH PROSTATE CANCER ON ANDROGEN DEPRIVATION THERAPY?
… numerous adverse side effects, including loss of muscle mass, strength, power, and physical function with concomitant increases in fat mass, fatigue, and bone fractures. Because strength training (ST) can reverse these factors in healthy older adults, it was hypothesized that ST would be effective …

Minimalist versus conventional running shoes : effects on lower limb injury incidence, pain and muscle function experienced distance runners
… if the gradual transition (accompanied by calf muscle training), from conventional to minimalist running shoes 1) increased the risk of lower limb pain or injury and 2) improved lower limb muscle function (endurance, flexibility and power) in experienced distance runners. In addition, the …

The Effects of Uphill vs. Level-Grade High-Intensity Interval Training on Key Physiological Indices of Distance Running
… and neuromuscular characteristics, also known as muscle power factors. The following chapters of this dissertation add to the growing body of literature showcasing the effects of high-intensity training on endurance performance, and sheds light on the efficacy of using uphill running as a training …

Effects of an In-season Resistance Training Program on Lower Extremity Power Output in Collegiate Basketball Players
… purpose of this study was to evaluate changes in muscle power performance in a horizontal (forward movement), vertical, and lateral directions in collegiate basketball players due to the presence of an in-season resistance training program (ISRTP). Four basketball teams were recruited for this …

The epidemiology of injury and risk factors associated with injury in first league field hockey players
… recorded the flexibility (sit and reach test), muscle power (standing broad jump), speed (40 m sprint) and endurance capacities (double winder) of all the players. Male players performed significantly better in the muscle power (p=0.0001), speed (p=0.0001) and muscle endurance (p=0.0001) tests …

Risk factors for lower limb musculoskeletal injuries in novice runners: a prospective study
… foot alignment, hamstring flexibility, balance, muscle power and a history of previous injury were risk factors for lower limb musculoskeletal injuries in novice runners; and (d) to determine if specific extrinsic factors, namely training frequency, session duration, and intensity were risk …

Advances in the visualization and analysis of boundary layer flow in swimming fish
… Total drag was used to determine the required muscle power output during swimming and compare that with existing muscle power data. τo and boundary layer thickness oscillated with undulatory phase. The magnitude of oscillation appears to be linked to body wave amplitude.

Assessment of joint kinetics in elite sprint cyclists
… cycling requires the production of explosive muscle power outputs up to very high pedalling rates. The ability to assess muscular function through the course of the sprint would aid training practices for high-level performers. Inverse dynamics provides a non-invasive means of estimating the …

Pharmacokinetics of neostigmine and pyridostigmine in man.
… of pyridostigmine to clinical evaluation of muscle power was examined in nine myasthenic patients during treatment with pyridostigmine in doses of 60 to 1080 mg per day. Five of the nine subjects demonstrated a trend towards a positive correlation and in two of them was this significant at …

Comparative effects of calcium channel antagonism and beta-1 selective blockade on exercise performance in physically active hypertensive patients
… test (Wingate test) to determine skeletal muscle power output, following 4 weeks ingestion of isradipine (2.5mg bd), atenolol (50mg bd) or placebo. Diastolic blood pressure at rest was reduced by both atenolol and isradipine, but was lowered to a greater extent by atenolol (83.3 vs 89.0 vs …
