An exploratory study examining the relationships between the personal, environmental and activity participation variables and quality of life among young adults with disabilities

Abstract Purpose: Despite the apparent importance of International Classification of Functioning, Disability and Health (ICF) framework in influencing the relationships between participation and quality of life (QoL), limited research has been given to comprehensive modelling of their influence. The purpose of this study was to explore the relationships between ICF components, participation factors and QoL among young adults with disabilities. Methods: This study tested a theoretically and empirically based explanatory model on 119 young adults with disabilities to examine how the variables of functional impact, financial behaviour, self-efficacy, neighbourhood environment, social support, social and community participation, satisfaction with participation influenced QoL. Analyses were performed with AMOS maximum likelihood parameter estimation. Results: The final model accepted in this study showed a well-fitted model, which explained 65% of the variance in QoL. Results from the statistical modelling indicated that all the ICF components and satisfaction with participation influenced the level of QoL in young adults with disabilities in either a direct or indirect manner. Conclusions: These findings provide evidence that young adults with disabilities have a very complex interaction of their activity participation, social membership, community connectedness, life satisfaction, suggesting that their context of QoL is shaped by how they make sense not only with their functional status, but also the social and community environment. Current findings further demonstrate that the ICF model of functioning and disability should be thought of as multidimensional and more than instrumental in character when being used by health and rehabilitation professionals. Implications for Rehabilitation This study supports the ICF model to include the concept of QoL as the outcome. Rehabilitation practitioners are encouraged to view the ICF model as multidimensional when designing interventions. Social context and support should be included when developing strategies to enhance QoL in youth transition to adulthood.
Throwing performance after resistance training and detraining

Terzis, G, Stratakos, G, Manta, P, and Georgiadis, G. Throwing performance after resistance training and detraining. J Strength Cond Res 22: 1198-1204, 2008-The purpose of the present study was to investigate the effect of short-term resistance training and detraining on shot put throwing performance. Eleven young healthy subjects with basic shot put skills participated in 14 weeks of resistance training, which was followed by 4 weeks of detraining. Shot put performance in four field tests was measured before (T1) and after (T2) resistance training and after detraining (T3). At the same time points, one repetition maximum (1RM) was measured in squat, bench press, and leg press. Fat-free mass (FFM) was determined with dual x-ray absorptiometry and muscle biopsies obtained from vastus lateralis for the determination of fiber type composition and cross-sectional area (CSA). 1RM strength increased 22-34% (p < 0.01) at T2 and decreased 4-5% (not significantly different) at T3. Shot put performance increased 6-12% (p < 0.05) after training and remained unaltered after detraining. FFM increased at T2 (p < 0.05) but remained unchanged between T2 and T3. Muscle fiber CSA increased 12-18% (p < 0.05) at T2. Type I muscle fiber CSA was not altered after detraining, but type IIa and IIx fiber CSA was reduced 10-12% (p < 0.05). The percentage of type IIx muscle fibers was reduced after training (T1 = 18.7 ± 4, T2 = 10.4 ± 1; p < 0.05), and it was increased at T3 compared with T2 (T3 = 13.7 ± 1; p < 0.05). These results suggest that shot put performance remains unaltered after 4 weeks of complete detraining in moderately resistance-trained subjects. This might be linked to the concomitant reduction of muscle fiber CSA and increase in the percentage of type IIx muscle fibers.
Relationship Between Countermovement Jump Performance and Multijoint Isometric and Dynamic Tests of Strength

The purpose of this investigation was to determine the relationship between countermovement vertical jump (CMJ) performance and various methods used to assess isometric and dynamic multijoint strength. Twelve NCAA Division I-AA male football and track and field athletes (age, 19.83 ± 1.40 years; height, 179.10 ± 4.56 cm; mass, 90.08 ± 14.81 kg; percentage of body fat, 11.85 ± 5.47%) participated in 2 testing sessions. The first session involved 1 repetition maximum (1RM) (kg) testing in the squat and power clean. During the second session, peak force (N), relative peak force (N·kg−1), peak power (W), relative peak power (W·kg−1), peak velocity (m·s−1), and jump height (meters) in a CMJ, and peak force and rate of force development (RFD) (N·s−1) in a maximal isometric squat (ISO squat) and maximal isometric mid-thigh pull (ISO mid-thigh) were assessed. Significant correlations (P ≤ 0.05) were found when comparing relative 1RMs (1RM/body mass), in both the squat and power clean, to relative CMJ peak power, CMJ peak velocity, and CMJ height. No significant correlations existed between the 4 measures of absolute strength, which did not account for body mass (squat 1RM, power clean 1RM, ISO squat peak force, and ISO mid-thigh peak force) when compared to CMJ peak velocity and CMJ height. In conclusion, multijoint dynamic tests of strength (squat 1RM and power clean 1RM), expressed relative to body mass, are most closely correlated with CMJ performance. These results suggest that increasing maximal strength relative to body mass can improve performance in explosive lower body movements. The squat and power clean, used in a concurrent strength and power training program, are recommended for optimizing lower body power.
Online Weight Training

McNamara, JM, Swalm, RL, Stearne, DJ, Covassin, TM. Online weight training. J Strength Cond Res 22, 1164-1168, 2008-The purpose of this study was to determine how a traditional weight training class compared to nontraditional classes that were heavily laden with technology. Could students learn resistance exercises by watching video demonstrations over the Internet? Three university weight training classes, each lasting 16 weeks, were compared. Each class had the same curriculum and workout requirements but different attendance requirements. The online group made extensive use of the Internet and was allowed to complete the workouts on their own at any gym that was convenient for them. Seventy-nine college-aged students were randomized into 3 groups: traditional (n = 27), hybrid (n = 25), and online (n = 27). They completed pretest and posttest measures on upper-body strength (i.e., bench press), lower-body strength (i.e., back squat), and knowledge (i.e., written exam). The results indicated that all 3 groups showed significant improvement in knowledge (p < 0.05). The online group did not require the students to attend class and may have resulted in significantly lower scores on the bench press (p < 0.05) and squats (p < 0.05). This study indicates that an online weight training course may improve knowledge but not strength. Possible reasons for a lack of improvement in the online group included lack of motivation, low accountability, and the possibility that the self-reported workouts were not accurate. These results suggest that there is a limit to how much technology can be used in a weight training class. If this limit is exceeded, some type of monitoring system appears necessary to ensure that students are actually completing their workouts.
Effects of Combination Oral Contraceptives on Strength Development in Women Athletes

Nichols, AW, Hetzler, RK, Villanueva, RJ, Stickley, CD, and Kimura, IF. Effects of combination oral contraceptives on strength development in women athletes. J Strength Cond Res 22(5): 1625-1632, 2008-This study was designed to investigate the effects of combination oral contraceptive agents (OCAs) on strength and torque production in collegiate women softball and water polo athletes who participated in a 12-week strength development program. A double-blind research design was used to mask subjects to the main outcome of interest. Thirty-one women collegiate softball and water polo players were divided into experimental (OCA users, n = 13), and control (non-OCA users, n = 18) groups. All subjects participated in the same supervised 12-week preseason strength development program. One-repetition maximum bench press (1RMBP), 10-repetition maximum leg extension (10RMLE), isokinetic peak torque bench press (IKBP), and isokinetic peak torque leg extension (IKLE) data were collected at weeks 0 (pre-test), 4, 8, and 12 (post-test). Significant increases in strength and torque production over time were identified regardless of group for 1RMBP, 10RMLE, and IKLE. No significant differences in IKBP torque production occurred during the 12-week strength training program. No significant differences in 1RMBP, 10RMLE, IKBP, or IKLE occurred between the OCA users and the non-OCA users groups. It was concluded that, within the limitations of the study, the use of combination OCAs did not provide sufficient androgenic effect to increase strength gains beyond the stimulus of the training protocol.
Acute Effects of Static, Dynamic, and Proprioceptive Neuromuscular Facilitation Stretching on Muscle Power in Women

Manoel, ME, Harris-Love, MO, Danoff, JV, and Miller, TA. Acute effects of static, dynamic, and proprioceptive neuromuscular facilitation stretching on muscle power in women. J Strength Cond Res 22(5): 1528-1534, 2008-The purpose of this study was to investigate the acute effects of 3 types of stretching-static, dynamic, and proprioceptive neuromuscular facilitation (PNF)-on peak muscle power output in women. Concentric knee extension power was measured isokinetically at 60°·s-1 and 180°·s-1 in 12 healthy and recreationally active women (mean age ± SD, 24 ± 3.3 years). Testing occurred before and after each of 3 different stretching protocols and a control condition in which no stretching was performed. During 4 separate laboratory visits, each subject performed 5 minutes of stationary cycling at 50 W before performing the control condition, static stretching protocol, dynamic stretching protocol, or PNF protocol. Three submaximal warm-up trials preceded 3 maximal knee extensions at each testing velocity. A 2-minute rest was allowed between testing at each velocity. The results of the statistical analysis indicated that none of the stretching protocols caused a decrease in knee extension power. Dynamic stretching produced percentage increases (8.9% at 60°·s-1 and 6.3% at 180°·s-1) in peak knee extension power at both testing velocities that were greater than changes in power after static and PNF stretching. The findings suggest that dynamic stretching may increase acute muscular power to a greater degree than static and PNF stretching. These findings may have important implications for athletes who participate in events that rely on a high level of muscular power.
Evaluating Sprinting Ability, Density of Acceleration, and Speed Dribbling Ability of Professional Soccer Players With Respect to Their Positions

Taşkin, H. Evaluating sprinting ability, density of acceleration, and speed dribbling ability of professional soccer players with respect to their positions. J Strength Cond Res 22(5): 1481-1486, 2008-The aim of this study is to evaluate sprinting ability, density of acceleration, and speed dribbling ability of professional soccer players with respect to their positions. A total of 243 professional soccer players were examined. These soccer players are playing in different leagues of Turkey. The F-MARC test battery, which was designed by FIFA, was used for soccer players. We did not find any statistical differences for 30-m sprint test and four-line sprint test values with respect to positions of soccer players (p > 0.05). On the other hand, there was a statistical difference for speed dribbling test values in terms of positions of soccer players (p < 0.05). It was found that the test values of defense players, midfielders, and forwards were better than the test values of goalkeepers (p < 0.05). In conclusion, this study, which was done during the training season, shows that there is a similarity between the abilities of professional soccer players for 30-m sprint and four-line sprint tests. Therefore, it is believed that there must be fast players in all positions in terms of sprint ability. There is a similarity among defenders, midfielders, and forwards in terms of speed dribbling ability; in contrast, the speed dribbling ability of goal keepers is different from the players in those three positions. Although there are many more speed dribbling exercises within the training programs of defenders, midfielders, and forwards, the speed dribbling ability test is not used much for goal keepers. Correspondingly, speed dribbling ability is not a specific indicator for goal keepers, and this test should not be used for the choice of goalkeepers.
A systematic review of qualitative studies on adjusting after stroke: lessons for the study of resilience

Abstract Purpose: To synthesize qualitative studies on adjusting after stroke, from stroke survivors’ and carers’ perspectives, and to outline their potential contribution to an understanding of resilience. Methods: A systematic review of qualitative studies in peer reviewed journals from 1990 to 2011 was undertaken. Findings from selected studies were summarized and synthesized and then considered alongside studies of resilience. Results: Forty studies were identified as suitable. These suggested that the impact of stroke was felt on many dimensions of experience, and that the boundaries between these were permeable. Nor was stroke as an adverse “event” temporally bounded. Adjustment was often marked by setbacks and new challenges over time. Participants identified personal characteristics as key, but also employed practical and mental strategies in their efforts to adjust. Relationships and structural factors also influenced adjustment after stroke. Conclusions: The impacts of stroke and the processes of adjusting to it unfold over time. This presents a new challenge for resilience research. Processes of adjustment, like resilience, draw on personal, inter-personal and structural resources. But the reviewed studies point to the importance of an emic perspective on adversity, social support, and what constitutes a “good” outcome when researching resilience, and to a greater focus on embodiment. Implications for Rehabilitation Stroke is a sudden onset condition which for around a third of people has long-term consequences. Stroke can cause a variety of physical and cognitive impairments, some of which may not be obvious to an outsider. As well as physical functioning, stroke can have a profound effect on survivors’ sense of self and on their relationships. Stroke survivors’ accounts suggest that relationships (including relationships with health care professionals) and structural factors (such as access to health services, employment possibilities and welfare systems) mediate efforts to adjust after stroke. While there is considerable overlap between notions of adjustment and resilience, the experiences of stroke survivors suggest further issues that need to be addressed in order to gain a more comprehensive understanding of resilience.
The risk of falling in young adults with neurological conditions: a systematic review

Abstract Purpose: To review systematically the literature on fall risk factors for young patients affected by neurological disorders. Method: A systematic search of all primary research-based literature on risk factors for falls or fall characteristics in young adults (mean age <55 years) published prior to July 2012 was conducted using 11 databases. Studies that focused on fall risk screening tools, fear of falling or interventions for fall prevention were excluded. Two reviewers independently agreed on eligibility and methodological quality and extracted data. Results: Twenty-three final studies were selected, including 21 observational studies; one randomised controlled trial and one qualitative study. An average of 50.2% of the 2776 total participants experienced at least one fall. Among the multiple risk factors studied, a reduced performance in balance and gait was consistently associated with falls, while the contribution of single physical and cognitive impairments was variable in different populations. Walking aids, wheelchair characteristics and environmental hazards are significant environmental risk factors. The heterogeneity of the assessment tools used to measure risk factors limited comparison across studies. Conclusion: Falling is a common problem among young patients affected by neurological disorders, although the risk of falling for a specific individual is difficult to predict and the risk of a severe fall-related injury has not yet been established. Implications for Rehabilitation Young patients with impaired gait and balance or medium to severe motor disability appear to be at increased risk of falling. Patients who are relatively independent and still participating in challenging activities have an increased exposure to fall-risk. Walking aids, wheelchair characteristics and environmental hazards are significant environmental risk factors. These risk factors should be monitored closely in the young neurological population to help prevent falls.
Kinetic Comparison of Free Weight and Machine Power Cleans

Jones, RM, Fry, AC, Weiss, LW, Kinzey, SJ, and Moore, CA. Kinetic comparison of free weight and machine power cleans. J Strength Cond Res 22(6): 1785-1789, 2008-The purpose of this investigation was to compare the kinetic characteristics of the power clean exercise using either free weight or machine resistance. After familiarization, 14 resistance trained men (mean ± SD; age = 24.9 ± 6.2 years) participated in two testing sessions. During the initial testing session, one-repetition maximum performance (1RM) was assessed in either the free weight or machine power clean from the midthigh. This was followed by kinetic assessment of either the free weight or the machine power clean at 85% of 1RM. One week after the initial testing session, 1RM performance, as well as the subsequent kinetic evaluation, were performed for the alternate exercise modality. All performance measures were obtained using a computer-interfaced FiTROdyne dynamometer (Fitronic; Bratislava, Slovakia). Maximum strength (1RM) and average power were significantly greater for the free weight condition, whereas peak velocity and average velocity were greater for the machine condition (p < 0.05). Although peak power was not different between modalities, force at peak power (free weights = 1445 ± 266 N, machine = 1231 ± 194 N) and velocity at peak power (free weights = 1.77 ± 0.28 m·s−1, machine = 2.20 ± 0.24 m·s−1) were different (p < 0.05). It seems that mechanical limitations of the machine modality (i.e., lift trajectory) result in different load capacities that produce different kinetic characteristics for these two lifting modalities.
Associations between social participation and subjective quality of life for adults with moderate to severe traumatic brain injury

Abstract Purpose: To examine the association between social participation and subjective quality of life (SQOL) for non-employed, community-dwelling adults with moderate to severe traumatic brain injury (TBI) at 1 year or greater post-injury. Method: A correlational study was conducted involving 46 participants. Social participation was measured using the Community Integration Questionnaire, Social Provisions Scale and the Adult Subjective Assessment of Participation. SQOL was measured using the Quality of Life and Health Questionnaire, Abdel-Khalek Happiness Scale and UCLA Loneliness Scale. Results: Higher levels of happiness and global quality of life were each associated with higher levels of enjoyment, satisfaction with performance and higher proportion of activities performed with others. Lower levels of loneliness were associated with higher levels of general social integration and higher levels of perceived social supports. There were no associations found between SQOL and the objective social participation measures of diversity, frequency (intensity) or proportion of activities performed outside of home. Conclusions: Findings contribute to the TBI literature in showing that it is: (a) the more subjective and not objectively measured nature of participation that is associated with SQOL and (b) positive and negative aspects of quality of life show different relationships with social participation variables. Implications for Rehabilitation A high proportion of individuals with traumatic brain injury (TBI) experiences reduced involvement in social participation (involvement in social and leisure activities and within a social network) and low subjective quality of life (SQOL). This study suggests that, by simply increasing the variety and frequency of social and leisure activities, there may be no positive influences on SQOL. Instead, this study suggests that, to increase SQOL, it is important to increase opportunities for individuals to participate with others and also to enhance their subjective experience of social and leisure activities. The large variance obtained of scores for social participation and SQOL provide a reminder to clinicians to maintain an individualized approach when working with individuals with TBI.
Power-Time, Force-Time, and Velocity-Time Curve Analysis of the Countermovement Jump: Impact of Training

Cormie, P, McBride, JM, and McCaulley, GO. Power-time, force-time, and velocity-time curve analysis of the CMJ: impact of training. J Strength Cond Res 23(1): 177-186, 2009-The purpose of this investigation was to examine the impact of training on the power-, force-, and velocity-time curves of the countermovement jump (CMJ) through both cross-sectional and longitudinal comparisons. The most novel aspect of this study was the analysis of these curves for the entire movement at a sampling frequency of 386-506 Hz averaged across 30 subjects. Thirty subjects, all men, participated in this investigation and included 12 athletes and 18 untrained men. Two major comparisons were conducted: 1) an acute, cross-sectional examination comparing experienced jumpers (jump height > 0.50 m; n = 12 men's athletes) with nonjumpers (jump height < 0.50 m; n = 14 untrained men), and 2) a longitudinal examination comparing performance before and after 12 weeks of power training (training group n = 10 untrained men; control group n = 8 untrained men). Data obtained from the baseline testing session of 14 subjects involved in the longitudinal study were used for the cross-sectional examination to represent the nonjumper group. The cross-sectional examination revealed significant (p ≤ 0.05) differences between jumpers and nonjumpers in peak performance variables (i.e., peak power, force, velocity, displacement) as well as over a range of time points throughout the power-, force-, velocity-, and displacement-time curves of the CMJ. Similar results were observed in the longitudinal examination, with power training eliciting significant changes to peak performance variables as well as significant changes to the power-, force-, velocity-, and displacement-time curves over a range of time points throughout the CMJ. This study illustrates that training status not only influences the peak performance variables of the countermovement jump but also impacts the shape of the power-, force-, velocity-, and displacement-time curves throughout the movement. Because analysis of peak performance variables offers little insight into how adaptations have occurred after training, examination of the changes to the power-, force-, velocity-, and/or displacement-time curves offers a simple yet powerful monitoring technique that practitioners can use to gain insight into the precise nature and timing of adaptations to training.
