Neuromuscular, anaerobic, and aerobic performance characteristics of elite power athletes.
1984
Various aspects of neuromuscular, anaerobic, and aerobic performance capacity were investigated in four powerlifters, seven bodybuilders, and three wrestlers with a history of specific training for several years. The data (means +/- SD) showed that the three subject groups possessed similar values for maximal isometric force per unit bodyweight (50.7 +/- 9.6, 49.3 +/- 4.1, and 49.3 +/- 10.9 N/kg, respectively). However, significant (P less than 0.05) differences were observed in the times for isometric force production, so that e.g., times to produce a 30% force level were shorter for the wrestlers and bodybuilders (28.3 +/- 3.1 and 26.4 +/- 6.6 ms) than that (53.3 +/- 23.7 ms) for the powe…
Investigating prismatic adaptation effects in handgrip strength and in plantar pressure in healthy subjects.
2020
Abstract Background Prismatic Adaptation (PA) is a visuomotor procedure inducing a shift of the visual field that has been shown to modulate activation of a number of brain areas, in posterior (i.e. parietal cortex) and anterior regions (i.e. frontal cortex). This neuromodulation could be useful to study neural mechanisms associated with either postural measures such as the distribution of plantar pressure or to the generation of muscle strength. Indeed, plantar pressure distribution is associated to activation of high-level cognitive mechanisms taking place within the posterior regions of the brain dorsal stream, especially of the right hemisphere. Conversely, hand force mostly rely on sen…
Effects of a home-based rehabilitation program in obese type 2 diabetics.
2012
International audience; OBJECTIVE: To assess, in obese type 2 diabetics (T2D), the impact of a home-based effort training program and the barriers to physical activity (PA) practice. METHOD: Twenty-three obese T2D patients (52.7 ± 8.2 years, BMI = 38.5 ± 7.6 kg/m(2)) were randomized to either a control group (CG), or an intervention group (IG) performing home-based cyclergometer training during 3 months, 30 min/day, with a monthly-supervised session. The initial and final measurements included: maximal graded effort test on cyclergometer, 6-minute walk test (6MWT) and 200-meter fast walk test (200mFWT), quadriceps maximal isometric strength, blood tests and quality of life assessment (SF- 3…
Inter- and intrarater reliability of two proprioception tests using clinical applicable measurement tools in subjects with and without knee osteoarth…
2017
Abstract Background The therapeutic value of proprioceptive-based exercises in knee osteoarthritis (KOA) management warrants investigation of proprioceptive testing methods easily accessible in clinical practice. Objective To estimate inter- and intrarater reliability of the knee joint position sense (KJPS) test and knee force sense (KFS) test in subjects with and without KOA. Design Cross-sectional test-retest design. Method Two blinded raters performed independently repeated measures of the KJPS and KFS test, using an analogue inclinometer and handheld dynamometer, respectively, in eight KOA patients (12 symptomatic knees) and 26 healthy controls (52 asymptomatic knees). Intraclass correl…
Ultrasonic Echo Intensity as a New Noninvasive In Vivo Biomarker of Frailty
2017
Objectives To investigate whether muscle quality based on echo intensity (EI) is associated with muscle strength (MS) and correlates with risk of frailty in elderly outpatients. Design Cross-sectional, experimental study. Setting Outpatient clinic. Participants Individuals aged 20 to 90 (N = 112). Individuals aged 20 to 59 participated as controls. Those aged 60 and older participated in the experimental group and were subdivided into robust, prefrail, and frail according to the Fried frailty criteria. Measurements EI, muscle thickness (MT), and subcutaneous fat thickness (SFT) of the anterior compartment of the thigh were measured using ultrasound images. MS was quantified using a hand dyn…
Musculoskeletal capacity of employees aged 44 to 58 years in physical, mental and mixed types of work
1987
The musculoskeletal capacity of 60 women and 69 men, average age 52.3 +/- 3.7 years was determined, including measurements of anthropometry, maximal isometric trunk flexion and extension, sit-ups, isometric hand grip strength and back mobility. According to the job and to cluster analysis, the subjects were divided into three dominating work groups; physical, mental, and mixed groups. The results showed significant differences in right hand grip strength of the women and in the number of sit-ups by men among the three work groups (p less than 0.05). The differences between the other tests were not significant, although the physical group in the women and either the physical or the mixed gro…
Combined Strength and Endurance Training Improves Health-Related Quality of Life in Healthy Middle-Aged and Older Adults
2012
The purpose of this study was to evaluate the effects of 21 weeks of strength and/or endurance training on health related quality of life (HRQoL) in 39-77 year-old healthy subjects. 108 men and 96 women were randomized into endurance, strength, or combined training groups and controls. Strength-group performed high-intensity strength training while endurance-group performed cycle training. Combined-group completed both training protocols. Leg extension strength and maximal oxygen uptake were measured. HRQoL was assessed with a Finnish version of SF-36 questionnaire. A significant training-induced difference was observed between groups (p=0.038) in the vitality dimension of HRQoL, which was …
Effects of Strength Training on Neuromuscular Function and Disease Activity in Patients with Recent-onset Inflammatory Arthritis
1994
Thirty-nine consecutive patients with recent-onset rheumatoid or psoriatic arthritis were randomly allotted for six months period either to the experimental progressive dynamic strength training group (EG, 10 women and 11 men; 41 +/- 10 yrs), or to the control group (CG, 10 women and 8 men; 45 +/- 11 yrs) who just maintained their habitual physical activities. All patients received antirheumatic medication throughout the experimental period. During the study period significant improvements took place in the EG in maximal muscle strength of all examined muscle groups (31.5% for the knee extensors, p0.001; 14.8% and 10.7% for the trunk flexors and extensors, p0.01; 27.8% and 20.4% for grip st…
Effects of strength and endurance training on metabolic risk factors in healthy 40â65-year-old men
2009
This study compared 21 weeks of combined high-intensity strength and endurance training with endurance or strength training only on metabolic risk factors in 40-65-year-old men. The healthy men (n=63) were randomized into endurance (E), strength (S), combined strength and endurance training (SE) and control (C) groups. S and E trained two times a week and SE 2+2 times a week. Systolic (SBP) and diastolic blood pressure decreased significantly both in E (-6+/-8 and -4+/-6 mmHg) and in S (-9+/-8 and -5+/-7 mmHg), but not in SE or C (P=0.003 for the difference in the changes of SBP between the groups). The changes in serum glucose and insulin during an oral glucose tolerance test did not diffe…
Acute Hemodynamic Responses to Combined Exercise and Sauna.
2020
AbstractThis study investigated acute hemodynamic, plasma volume and immunological responses to four loading protocols: sauna only, and sauna after endurance, strength or combined endurance and strength exercise. Twenty-seven healthy, slightly prehypertensive men (age 32.7±6.9 years) were measured at PRE, MID (after exercise), POST, POST30min and POST24h. The measurements consisted systolic and diastolic blood pressure, heart rate, body temperature and concentrations of high-sensitive C-reactive protein, white blood cells and plasma volume measurements. Endurance+sauna showed significant decreases in systolic blood pressure at POST (–8.9 mmHg), POST30min (–11.0 mmHg) and POST24h (–4.6 mmHg)…
