PURPOSE: To compare the effects of a 10-week training program with two different exercises - traditional hamstring curl (HC) and Nordic hamstrings (NH), a partner exercise focusing the eccentric phase - on muscle strength among male soccer players.…

The purpose of this paper is to test the hypothesis that daily physical activity over a period of 15 years has been beneficial to aerobic fitness in young male and female participants (13-27 years) in the Amsterdam Growth and Health Longitudinal…

When running indoors on a treadmill, the lack of air resistance results in a lower energy cost compared with running outdoors at the same velocity. A slight incline of the treadmill gradient can be used to increase the energy cost in compensation.…

The primary purpose of this investigation was to examine the physiological profile of a National Hockey League (NHL) team over a period of 26 years. All measurements were made at a similar time of year (pre-season) in 703 male (mean age SD = 24 4 y)…

Growth trends in the cross-sectional area of the quadriceps femoris (CSA(QF)) and its dynamic strength in 12 teenage tennis players (six boys and six girls), aged from 10.7 to 13.2 years at the onset of the study, were investigated through a 2-year…

Measuring lower body strength is critical in evaluating the functional performance of older adults. The purpose of this study was to assess the test-retest reliability and the criterion-related and construct validity of a 30-s chair stand as a…

A 33-yr follow-up of peak oxygen uptake and related variables of former physical education students.In 1949, 27 female and 26 male physical education students were studied at a mean age of 22 and 25 yr, respectively. They were restudied in 1970 and 1982. Measurements included oxygen uptake, heart rate, and pulmonary ventilation during submaximal…

Biomechanical models generally assume that muscle fascicles shorten uniformly. However, dynamic magnetic resonance (MR) images of the biceps brachii have recently shown nonuniform shortening along some muscle fascicles during low-load elbow flexion…

PURPOSE: The aim of this investigation was to test the hypothesis that a 3-min all-out cycling test would detect a change in critical power (CP) after a 4-wk interval training intervention. METHODS: Nine habitually active subjects completed a ramp…
-
PURPOSE: We tested the hypothesis that a 3-min all-out cycling test would provide a measure of peak oxygen uptake (VO2peak) and estimate the maximal steady-state power output. METHODS: Eleven habitually active subjects performed a ramp test, three…

BACKGROUND: Cross-sectional data have shown that sarcopenia and fat accumulation are associated with aging and can be limited by structured physical training. However, it is often difficult to maintain a long-term compliance to training programs. It…

Based on a theoretical approach from world record running data, we have previously calculated that the most suitable duration for measuring maximal aerobic velocity (Vamax) by a field test was 5 min (Vamax(5)). The aim of this study was, therefore,…

PURPOSE: To describe changes in objectively assessed physical activity by socioeconomic status (SES) between 1999-2000 and 2005 in 9-yr-old children living in Oslo, Norway. METHODS: Two cross-sectional studies were conducted in 1999-2000 and 2005.…

Knee injuries are common and account in various sports for 15-50% of all sports injuries. The cost of knee injuries is therefore a large part of the cost for medical care of sports injuries. Furthermore, the risk of acquiring a knee injury during…

"Will come out in Memory and Cognition, with some revisions. The initial discussion is the thing to focus on (theres a lot of theoretical weight being carried by whats in fact a rather puny experimental result, but we wanted to get the discussion…

CONTEXT: Obesity is a well-established risk factor for coronary heart disease (CHD), but whether regional fat distribution contributes independently to risk remains unclear. OBJECTIVE: To compare waist-hip ratio (WHR) and waist circumference in…
