The relationship between heart rate as an indicator of work hardness and results of dynamometry

Heart rate is associated with work hardness and increase linearly with its increasing. In the average of energy consumption, heart rate measurement is simple but non-accurate method for calculation of work hardness. Our purpose in this research was to evaluate the relationship between heart rate and dynamometry results with hypothesis of work hardness effectiveness on the human power. This study was conducted on 102 porcelain workers. Participants were selected randomly. The research tools include stethoscope, the dynamometer. Heart rate, and pinch, grip, and back-leg-chest force were measured and relationships between variables were analyzed with Pearson correlation test and independent T-test using Spss 16 software. The average heart rate of participants were 4.11 ± 1.79 with minimum 60 and maximum 120. The average force of pinch, grip, and back-leg-chest were 8.9 ± 3.20, 4.2 ± 4.5 and 9.36 ± 6.55, respectively. Work hardness for 3.86% of workers were light, 7.12% were moderate and 1% were heavy. Pinch, grip, and back-leg-chest force relation with heart rate were not significant (r=0.01, p=0.85), (r=-0.03, p=0.74), and (r=0.05, p= 0.59), respectively. There was no correlation between heart rate and work hardness. So we can't use the dynamometry results to determine of work hardness.     

Association between handgrip strength,walking, age-related illnesses and cognitive status in a sample of Portuguese centenarians

Background

Centenarians are a growing population in Europe and present significant variability in motor and cognitive functions. The aim of our study was to characterize health status, as well as cognitive and motor functions in a group of Portuguese centenarians. In addition, our study also aimed at analyzing the relationship between cognitive functions and the burden of diseases affecting the elderly.

Methods

Fifty-two centenarians were evaluated using the Mini-Mental State Examination, short version. Walking-related parameters (velocity and time spent in the 3 m walk test), grip strength and number of age-related illnesses were also measured. The relationship between cognitive scores and time spent in the three metre walk test, velocity, grip strength and number of diseases was analysed.

Results

Cognitive scores showed a positive correlation with both handgrip strength and time spent in the three metre walk. In contrast, no association was found between cognitive scores and the presence/absence of disease, walking velocity or number of diseases present.

Conclusions

These results suggest that in centenarians, cognitive functions may be related with motor functions.

     

Relationship between balance and gait stability in healthy older adults

Age-related adaptations during walking create a more stable walking pattern, which is less effective for forward progression and might be related to balance deficiencies. This study determined the relationship between walking stability and measures of balance in older adults. Seventeen older and 20 young adults performed the Berg Balance Test (BBT) and walked 10 m. Walking velocity (WV) and cadence were measured, and a gait-stability ratio (GSR) was calculated. Higher GSR indicated that a greater portion of the gait cycle was spent in double-limb support. Age-group comparisons established declines in BBT scores and WV and increases in GSR with age. Significant relationships were identified for BBT Item 12 (alternate stepping on a stool) with WV (r =.58, r(2) =.34) and GSR (r = -.74, r(2) =.54). The correlation of BBT Item 12 with GSR was stronger than with WV (p <.05). Results indicated a strong relationship between increased gait stability and decreased balance for a dynamic weight-shifting task. Therefore, GSR is a better indicator of balance deficits during walking than is WV alone.     

Relation between hand grip strength,respiratory muscle strength and spirometric measures in male nursing home residents

Abstract

Adverse-outcomes related to sarcopenia are mostly mentioned as physical disability. As the other skeletal muscles, respiratory muscles may also be affected by sarcopenia. Respiratory muscle strength is known to affect pulmonary functions. Therefore, we aimed to investigate the relations between extremity muscle strength, respiratory muscle strengths and spirometric measures in a group of male nursing home residents. Among a total of 104 male residents, residents with obstructive measures were excluded and final study population was composed of 62 residents. Mean age was 70.5?±?6.7 years, body mass index: 27.7?±?5.3?kg/m² and dominant hand grip strength: 29.7?±?6.5?kg. Hand grip strength was positively correlated with maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) (r?=?0.35, p?<?0.01 and r?=?0.26, p?<?0.05, respectively). In regression analysis, the only factor related to MIP was hand grip strength; among spirometric measures only parameter significantly related to grip strength was peak cough flow (PCF). The association of PCF with grip strength disappeared when MIP alone or “MIP and MEP” were included in the regression analysis. In the latter case, PCF was significantly associated only with MIP. We found peripheric muscle strength be associated with MIP and PCF but not with MEP or any other spirometric parameters. The relation between peripheral muscle strength and PCF was mediated by MIP. Our findings suggest that sarcopenia may affect inspiratory muscle strength earlier or more than the expiratory muscle strength. Sarcopenia may cause decrease in PCF in the elderly, which may stand for some common adverse respiratory complications.     

Borderline personality symptomatology and history of domestic violence among women in an internal medicine setting

In this study of primary care patients, we examined the relationship between a history of domestic violence (measured with the Severity of Violence Against Women Scale [SVAWS]) and borderline personality (measured with the Self-Harm Inventory [SHI] and the Personality Diagnostic Questionnaire-4 [PDQ-4]). We elected borderline personality for examination because several diagnostic criteria sets describe relationship features suggestive of partner abuse. In this study, both measures of borderline personality were highly related to each other (r = .73, p < .001) as well as to the SVAWS (r = .70, p < .001, for the SHI; r = .73, p < .001, for the PDQ-4). Using diagnostic cutoff scores on the measures for borderline personality, 64.0% of those with histories of domestic violence scored in the positive range on either or both measures, while only 11.1% of nonabused women did. We discuss the clinical implications of these findings.     

ABSTRACTS OF The 2nd Asian ISSAM Meeting on the Aging Male Taipei,Taiwan March 6–9, 2003

Background.?It is of interest to understand whether impaired physical function is associated with health-related quality-of-life (HRQOL). We examined upper and lower body physical function and its relationship with two domains of HRQOL among men.

Methods.?We conducted a population-based observational study of musculoskeletal health among Boston, MA residents, the Boston Area Community Health/Bone Survey. Participants were 1219 randomly-selected Black, Hispanic, and White males (30–79 years). Upper body function was measured using hand grip strength, while lower body function was measured by combining a timed walk and a chair stand test. HRQOL was measured using the physical (PCS-12) and mental health (MCS-12) component scores of the SF-12. Multivariate linear regression models were used to estimate the association between poor function and HRQOL.

Results.?There was a significant association of poor upper body physical function with the MCS-12 (β coefficient:??4.12, p?=?0.003) but not the PCS-12 (β coefficient: 0.79, p?=?0.30) compared to those without poor function. Those with poor lower body physical function had significantly lower PCS-12 scores (β:??2.95, p?=?0.007), compared to those without poor function, but an association was not observed for MCS-12 scores.

Conclusions.?Domains of physical function were not consistently related to domains of HRQOL.     

Effectiveness of an educational intervention to increase knowledge and reduce use of risky behaviors associated with cumulative trauma in office workers

OBJECTIVE: This pilot project assessed the effectiveness of an intervention to increase knowledge and reduce risky behaviors related to cumulative trauma disorders (CTD) in office workers. STUDY DESIGN: All 124 employees from the administrative offices of a health maintenance organization were invited to participate. Subjects were followed across time using an identification number. Data were collected via questionnaire in June 1994 (pretest1) (N=84), August 1994 (pretest II) (N= 63) and September 1995 (posttest) (N=40). The yearlong intervention focused on functional activities to prevent CTD. RESULTS: of chi-square analyses for the 40 subjects who completed all surveys indicated this intervention significantly increased overall knowledge of CTD (p =.002). Significant changes in self-reported hand/wrist (p =.016) and neck/shoulder (p =.003) posture were also found. CONCLUSIONS: This study is a first step in identifying effective educational interventions to increase knowledge and reduce risk factors related to CTD in office workers.     

Cardiorespiratory fitness, obesity, and functional limitation in older adults

One hundred forty-six abdominally obese adults age 60-80 yr were studied to investigate the interaction between cardiorespiratory fitness (CRF) and obesity on functional limitation. Obesity was determined by fat mass (FM), CRF was determined by a maximal treadmill test, and functional limitation was based on 4 different tasks that are predictive of subsequent disability. Both FM (r = -.34, p ≤ .01) and CRF (r = .54, p ≤ .01) were independently associated with functional limitation in bivariate analysis.After further control for sex, age, and the interaction term (CRF × FM), FM was no longer independently associated with functional limitation (p = .10). Analyses were also based on sex-specific tertiles of FM and CRF. The referent group demonstrated significantly lower functional limitation than the low-CRF/low-FM and the low-CRF/high-FM groups (both p ≤ .05). These results highlight the value of recommending exercise for abdominally obese adults.     

Preventing Rsi/Wruld: use of esthesiometry to assess hand tactile sensitivity of slaughterhouse workers

This research was conducted with slaughterhouse female workers in the municipality of S?o Miguel do Igua?u, state of Parana, Brazil. The sample was composed of 103 women aged 25 to 40 ( 7.57 years, and the study aimed to verify the nerve conduction of the median nerve. An esthesiometer consisting of a Semmes-Weinstein monofilaments was used to measure the hand skin sensitivity in the region of the median nerve and a Jamar? hand dynamometer, which was used to determine the handgrip strength. About 81% of individuals had normal sensitivity with 0.05 g and average levels of handgrip strength in dominant hand (DH) of 35.30 kgf (( 3.10) and in the non-dominant hand (NDH) of 28.30 ( 3.09 kgf. 14% of individuals had reduced sensitivity, with values equivalent to 0.2 g and 2.0 g (blue and violet) and levels of handgrip strength in the DH equal to 28.10 kgf (( 2.90) and in the NDH of 26.40 kgf (( 3.28). 5% of individuals showed bilateral sensitivity deficit (4.0 g) and levels of handgrip strength in the DH of 16.10 kgf (( 2.10) and in the NDH of 18.20 kgf (( 3.28), resulting in a strong correlation between handgrip strength and sensitivity of the median nerve (r = 0.786) between variables dominant hand (DH) and (r = 0.626) for the non-dominant hand (NDH). It could be concluded that assessing the nerve conduction of the median nerve by hand esthesiometry can be an important tool in preventing the Carpal Tunnel Syndrome.     

Effects of long-acting testosterone undecanoate on bone mineral density in middle-aged men with late-onset hypogonadism and metabolic syndrome: results from a 36 months controlled study

We evaluated the effects of long-term testosterone replacement therapy (TRT) on the bone mineral density (BMD) in obese patients with metabolic syndrome (MS) and late-onset hypogonadism (LOH). Sixty men (mean age 57 ± 10) with low serum testosterone (T < 320 ng/dL) and MS regardless the presence of osteoporosis were enrolled. Forty men received intramuscular T-undecanoate (TU) four times/year for 36 months and 20 age-matched hypogonadal men with MS in whom T treatment was contraindicated were used as controls. Hormonal, biochemical markers, vertebral and femoral BMD by dual-energy x-ray absorptiometry were measured. At baseline, overall patients had mild osteopenia (lumbar BMD= 0.891 ± 0.097 g/cm(2); femoral BMD= 0.847 ± 0.117 g/cm(2)). TU induced a significant improvement of bone mass after 36 months (lumbar BMD=1.053 ± 0.145 g/cm(2); p < 0.002; femoral BMD=0.989 ± 0.109; p < 0.003 g/cm(2)) with a 5%/year increase and a significant reduction in hs-CRP without changes in body mass index. A direct relationship between serum T and BMD increments at the lumbar (r(2)?= 0.66, p < 0.0001) and femoral (r(2)?=0.52, p < 0.0001) sites was demonstrated. Study adherence was 50% without serious side effects. Long-term TRT in middle-aged men with LOH and MS determines a significant increase in both vertebral and femoral BMD related to increased serum T levels, probably independently from estradiol modifications.     

Hispanic Acculturation Index: Advancing Measurement in Acculturation

Hispanics experiences with cultural change are particularly important given its relationship with individual and family functioning. The current study attempts to improve the acculturation scale sensitivity by expanding response options, adding item content emphasizing cultural values, and improve scale orthogonality consistent with existing theory. Results indicate acceptable reliability for the Hispanic Acculturation Index Hispanic (HAI-H; α = .93) and White American Scales (HAI-WA; α = .88) with adequate model fit. Strong correlations between ethnic identity and the HAI-H (r = .83, p < .01) and HAI-WA (r = .61, p < .01) and a non-significant relationship with a measure of social support provided evidence supporting the scales' construct validity. Moreover, ethnicity was a statistically significant variable for HAI-H (β = .77, p < .01) and HAI-WA (β = .53, p < .01) scores.     

The aging male in African ethnic cultures

Objective.?To test the relationship between gonadal status and objective measures and determinants of physical performance in older men and their determinants.

Methods.?The study included 455?≥?65 year older men of InCHIANTI study, Italy, with complete data on testosterone levels, hand grip strength, cross-sectional muscle area (CSMA), short physical performance battery (SPPB). Linear models were used to test the relationship between gonadal status and determinants of physical performance.

Results.?Three different groups of older men were created: (1) severely hypogonadal (N?=?23), total testosterone levels ≤230?ng /dl; (2) moderately hypogonadal (N?=?88), total testosterone >230 and?N?=?344), testosterone levels ≥350?ng/dl. With increased severity of hypogonadal status, participants were significantly older while their BMI was substantially similar. In the age and BMI adjusted analysis, there was a significant difference in haemoglobin levels, hand grip strength and SPPB score (p for trend?p for trend?=?0.004) and haemoglobin (p for trend?Conclusions.?In older men, gonadal status is independently associated with some determinants (haemoglobin and muscle strength) of physical performance.     

The effect of 6 months training on leg power, balance, and functional mobility of independently living adults over 70 years old

Where strength training has been used in conjunction with functional-task training in older people, not only have there been improvements in leg strength but also improved function has been measured (e.g., Skelton & McLaughlin, 1996). Many studies use participants from care homes rather than community dwellers. We investigated changes in leg power, balance, and functional mobility in community-dwelling sedentary men and women over 70 years of age (n = 6 for training group [TR]; n = 10 for control group [CN]). Progressive training took place over 24 weeks using seated and nonseated exercise. For TR, leg power increased 40%, from 108 +/- 40 to 141 +/- 53 W (p < .01); dynamic balance increased 48%, from 22.3 +/- 7.9 to 33.1 +/- 6.1 cm (p < .01; functional reach); and functional mobility increased 12%, from 7.46 +/- 1.32 to 6.54 +/- 1.41 s (p < .05; timed walk). CN showed no significant change. In conclusion, a community-based exercise program led to large improvements in leg-extensor power, dynamic balance, and functional mobility.     

A Preliminary Investigation of the Effectiveness of Attachment Therapy for Adopted Children with Reactive Attachment Disorder

The purpose of this preliminary investigation was to examine the effectiveness of attachment therapy for adopted children diagnosed with Reactive Attachment Disorder (RAD). Although attachment therapy is widely utilized in the practice community, outcomes of such therapy have not been well documented. In this study a pretest–posttest one-group design was used with a sample of 24 adopted children who received attachment therapy from trained, licensed therapists. Therapy was funded by the Georgia Office of Adoptions under a contract with a non-profit adoptive parent advocacy group which provided training of therapists and direct services to families. RAD was measured with the Randolph Attachment Disorder Questionnaire (RADQ), Third Edition; functional impairment was measured with the Child and Adolescent Functional Assessment Scale (CAFAS). Statistically significant decreases in scores on the RADQ and CAFAS from pretests to posttests indicate improvement for the children who received therapy. In spite of methodological limitations, the current study adds to the limited knowledge about effective treatment for RAD.     

September 11 attacks: prior interpersonal trauma, dysfunctional cognitions, and trauma response in a midwestern university sample

Undergraduate college students (N = 133) were assessed for posttrauma and depressive symptomatology, posttrauma cognitions, and previous traumatic experiences 1 month after the September 11 attacks in the United States. Negative beliefs regarding oneself and the world mediated the relationship between prior interpersonal trauma and acute trauma symptoms. Acute depression acted as a mediator between prior interpersonal trauma and negative cognitions of oneself and self-blame cognitions. The results suggest that even in a nonclinical, nontreatment seeking college sample, prior traumatic events can play an important role in an individual's short-term adjustment following indirect exposure to a significant trauma. The differential relationship of negative beliefs on acute trauma symptoms and depression is discussed.     

Physical and psychological outcomes of a supported physical activity program for older carers

This study evaluated health benefits of a supported physical activity program for 116 older carers (mean age 64.4 [SD = 7.9], 85% women). Participants undertook a 6-month center-based physical activity program (strength training, yoga, or Tai Chi). Eighty-eight participants (76%) completed the program. Multivariate repeated-measures ANOVA identified overall significant improvement postintervention (p = .004). Univariate analyses revealed significant improvements for balance, strength, gait endurance, depression, and SF-36 (physical component; p < .05). There was no change in the Zarit Carer Burden Scale (p > .05). Change in performance scores did not differ significantly between those with higher and lower attendance at classes, although there was significantly greater improvement in gait endurance and balance (p < .05) in those attending classes run twice weekly than in those attending once-weekly classes. In conclusion, a carer physical activity program, providing additional carer support to facilitate participation, can achieve high levels of involvement by carers and significant health benefits.     

Development of a score for assessing severity, predicting interventions and prognosis of musculoskeletal disorders

Musculoskeletal disorders (MSD's) are a constellation of disorders. There is no single tool available which guides the clinicians to predict the severity, intervention and recovery period of the patients who is suffering from different musculoskeletal disorder. In this paper authors tried to categorize the severity of the musculoskeletal discomfort and the prognosis of the recovery period. The questionnaire was formulated using different epidemiological risk factor of the development of MSD and the effect of MSD on physical and psychosocial factors. The questionnaire contains 13 questions which include seven direct (rating was 0, 2, 4, 6, 8 and 10) and six indirect (rating was 0, 1, 2, 3, 4 and 5) questions. Results revealed a significant correlation with the prognosis of recovery and the actual recovery period (r= 0.80). It also showed a significant correlation between the total severity score and the actual recovery (r=0.82) period. Depending on the prognosis of the recovery the severity score was segregated in four categories as mild, moderate, severe and complicated. Due to small sample size the prognosis of recovery for higher severity score could not be plotted.     

A randomized study of CrossFit Kids for fostering fitness and academic outcomes in middle school students

Within the context of school-based physical education (PE), a strength and conditioning program called CrossFit Kids (CFK) has emerged as a potential intervention for positively impacting students. The purpose of this study was to evaluate through a randomized-controlled trial how academic and health-related fitness outcomes differed for middle school students (age = 12.73; 55.3 % male) who participated in a school-based CFK program (n=72) as compared to a group of students who participated in PE class (n=72). Questionnaire data were collected twice across the 9-month academic year and combined with FitnessGram and grade data.Students in both the intervention and comparison groups increased in health-related fitness outcomes (all p values < .017), and there was a significant treatment group by time interaction on school-reported grades [F(1, 124) = 7.270, p = .008, η_P^2 = .055].Significant gender by time interaction effects were found for the relationship between CFK or PE participation and health-related fitness outcomes, but there were no significant interaction effects by gender on academic outcomes. Because developmental outcomes are conditional and result from the coaction of many factors, the findings suggest that some elements of CFK might be beneficial to build skills yet disadvantageous to academic outcomes.     

Cognitive impairment and effects on upper body strength of adults with dementia

The purpose of this investigation was to examine the association between cognitive ability and upper body muscle strength. Two sources of existing data were pooled for this examination. Thirty-eight older participants diagnosed with Alzheimer's disease or dementia (25 women, 13 men; age = 83.2 +/- 5.6 years, MMSE score = 16.75 +/- 7.04, M +/- SD) underwent an assessment of grip strength via handheld dynamometry. Multiple-regression analysis indicated that cognitive status was a significant predictor of strength and, when combined in a model with age and sex, explained 57% of the between-individuals variance in handgrip strength. The findings from this exploratory investigation suggest that dementia is associated with strength loss, a key contributor to functional disability; this further justifies efforts to investigate mechanisms responsible for this decay and to preserve muscle integrity by integrating physical activity interventions, notably, muscle strengthening, into the lifestyle of adults with dementia.
