Effects of heavy resistance/power training on maximal strength, muscle morphology, and hormonal response patterns in 60-75-year-old men and women.
2002
Eleven women (TRW; 64 ± 4 yrs) and ten men (TRM; 65 ± 5 yrs) participated in the strength/power training twice a week for 24 weeks. Basal concentrations of serum total and free testosterone, growth hormone (GH), dehydroepiandrosterone sulfate (DHEAS), cortisol and sex hormone binding globulin (SHBG) as well as acute responses of serum total and free testosterone, growth hormone (GH) were measured. Maximal 1RM strength in the squat, chair rise time and muscle fibre distribution and areas of type I and IIa and IIb of the vastus lateralis were also examined. 1RM squat increased in TRW by 26 (SDIO) % (p < .001), and in TRM by 35(7) % (p < .001) and chair rise time improved in both groups…
Food deprivation decreases the exertion-induced acid hydrolase response in mouse skeletal muscle
1988
Strenuous prolonged running causes muscle fibre necrosis in skeletal muscles. The muscle injury is associated with inflammation and a strong increase in the total activities of certain acid hydrolases a few days after exertion. The activity changes of acid hydrolases quantitatively well reflect the severity of histopathological changes during the myopathy (for review see Salminen, Acta Physiol Scand [Suppl 539] 1985). In this study male NMRI-mice were exposed to a protocol of fasting and refeeding together with or without a 6 h run on a treadmill at 13.5 m.min-1. The animals were killed 4 days after the exercise and samples from the red part of quadriceps femoris were analyzed for arylsulfa…
Effects of 8 weeks' endurance training on skeletal muscle metabolism in 56?70-year-old sedentary men
1977
The effects of 8 weeks' endurance training on muscle metabolism at rest and after a submaximal bicycle ergometer exercise were studied in 31 previously sedentary men, aged 56-70. Training consisted of 3-5 one hour exercise bouts per week including walking-jogging, swimming, gymnastics and ball games. The effects of training were similar to those previously reported for younger men. Mean maximal oxygen uptake increased (11%), as did the resting values for muscle glycogen concentration, the enzymes representing aerobic energy metabolism (malate dehydrogenase, succinate dehydrogenase), and also some of the anaerobic enzymes (creatine phosphokinase, lactate dehydrogenase). Lactate production du…
Aerobic performance capacity in athletes
1978
Maximal oxygen uptake (max\(\dot V\)O2) in leg and arm work, succinate dehydrogenase activity (SDH) and percentage of slow twitch fibers (%ST fibers) in M. vastus lateralis (VL), M. gastrocnemius c.l. (GL) and M. deltoideus (D) were studied in 89 athletes practising 11 different sport events. It was found that maximal oxygen uptake correlated positively with %ST fibers and SDH activity in M. VL. The SDH activity and %ST fibers in M. VL correlated also with one another. The results suggest that oxidative capacity of the muscles is not the limiting factor for maximal oxygen uptake. The role of the oxidative capacity of the muscles might be important during submaximal work of long duration and…
Structural validity of the Finnish Manchester-Oxford Foot Questionnaire (MOXFQ) using the Rasch model.
2019
Background: The 16-item patient-reported Manchester-Oxford Foot Questionnaire (MOXFQ) with subscales of pain, social interactions, and walking/standing has been claimed for strongest scientific evidence in measuring foot and ankle complaints. This study tests the validity of the Finnish MOXFQ for orthopaedic foot and ankle population using the Rasch analysis. Methods: We translated the MOXFQ into Finnish and used that translation in our study. MOXFQ scores were obtained from 183 patients. Response category distribution, item fit, coverage, targeting, item dependency, ability to measure latent trait (unidimensionality), internal consistency (Cronbach's alpha), and person separation index (PS…
Anterior cervical discectomy and fusion with ROI-C peek cage: cervical alignment and patient outcomes
2014
OBJECTIVE: The intersomatic cage ROI-C one is a new promising system in anterior cervical discectomy with subsequent fusion. METHODS: Patients were studied prospectively. ROI-C cages were used in consecutive 32 patients. Intraoperative parameters, clinical features and dysphagia scores were recorded. Radiographs evaluated the height of intervertebral space, the cervical Cobb angle and implant positioning. Data were collected on the last day of hospital stay, at 6 weeks, at 3, 6, 12 and 24 months. RESULTS: A total of 32 cages were implanted. One patient had transient dysphagia. The intervertebral height and the cervical Cobb angle were significantly improved at 24 months follow-up (P < 0.05)…
Differences in axial segment reorientation during standing turns predict multiple falls in older adults
2011
Author's version of an article in the journal: Gait and Posture. Also available from the publisher at: http://dx.doi.org/10.1016/j.gaitpost.2012.05.013 Background: The assessment of standing turning performance is proposed to predict fall risk in older adults. This study investigated differences in segmental coordination during a 360° standing turn task between older community-dwelling fallers and non-fallers. Methods: Thirty-five older adults age mean (SD) of 71 (5.4) years performed 360° standing turns. Head, trunk and pelvis position relative to the laboratory and each other were recorded using a Vicon motion analysis system. Fall incidence was monitored by monthly questionnaire over the…
External rotation strength deficit after hip resurfacing surgery.
2008
The aim was to assess the effect of resurfacing hip arthroplasty on hip muscle function, when, in the posterior approach, the piriformis tendon and outer rotators of the hip joint were divided. The unoperated side was used as a control.Thirty-three consecutive patients (mean age 55 years, 73% males) were operated using the posterior approach. Main outcome measures were isometric muscle strength of external and internal rotators and extensors of the hip and hip pain.Hip external rotation strength (p0.001) and leg extension strength (p0.001) were significantly lower on the operated side compared with the un-operated side prior to the surgery. On the operated side external rotation strength de…
Serum hormone concentrations during prolonged training in elite endurance-trained and strength-trained athletes.
1989
A study of 1 year was performed on nine elite endurance-trained athletes (swimmers) and on eight elite strength-trained athletes (weightlifters) in order to examine the effects of training on the endocrine responses and on physical performance capacity. The measurements for the determination of serum hormone concentrations were performed at about 4-month intervals during the course of the year. The primary findings demonstrated that during the first and most intensive training period of the year in preparing for the primary competitions similar but statistically insignificant changes were observed in the concentrations of serum testosterone, free testosterone and cortisol in both the endura…
Physical training and connective tissues in young mice-heart
1976
The effect of physical training on the chemical properties of the heart tissues was studied in male mice of NMRI-strain. The mice to be trained and their controls were about 2 weeks old at the beginning of the training, which took place on 5 degrees inclined treadmill 5 days a week for 3-22 weeks. The duration of daily exercise was progressively increased over the first 3 weeks. The final daily exercise bouts were 50 and 80 min for moderate programs and 180 min for the intensive program at a speed of 30 cm/s. The whole heart or the ventricles were used for the analyses. We found no significant changes related to training in the concentrations of nitrogen, hexosamines, and hydroxyproline bot…
