Conference paper (peer-reviewed)abstract
- Introduction: Physical activity has a positive impact on physical and psychological well-being (Delisle, Werch, Wong, Bian, & Weiler, 2010), as well as social relations and skills development (Lamu & Olsen, 2016; Perkins & Williamon, 2014). Adopting a “healthy organization” culture through health programs, with strong senior and middle management support, and using interventions can promote health at workplaces (Rajaratnam et. al., 2014). We, therefore, consider it relevant to have physical activity, social relations and skill development as the starting point in a tabletennis intervention at the workplace.Aim: The aim was to develop, implement, and evaluate an intervention for improving health and wellbeing in the workplace by introducing table tennis.Methods and results: The intervention design consisted of two workshops and five table tennis sessions. Thirteen employees from a warehouse within the retail sector participated in the intervention. The participants had various backgrounds in table tennis and sport in general, different motives to participate, and came from different groups of employees (management and stock). After an introductory workshop, two table tennis coaches held one training session a week over the fiveweek intervention period. The employees were divided in to two groups and each group had a 45-minute session. The evaluation is in progress at present. Pre- and post-measurement has been conducted using health questionnaires Short Form 36 Health Survey (SF-36) and International Physical Activity Questionnaire (IPAQ). These will be analysed using a Bayesian paired t-test analysis. Based on the results of the questionnaire focus group interviews will be conducted with participants. Three focus groups of 4-5 participants in each group. The questions will focus on 24 experiences of the intervention and reflections on future directions for table-tennis and wellbeing activities at the workplace. Finally, there will be a workshop pointing out future directions for sport-based health activities at the workplace.

Journal article (peer-reviewed)abstract
- This study aimed to explore whether a six-week intervention, based on participation in outdoor exercise, including activity-tracking devices and combined with individual consulting sessions, can both increase physical activity and yield positive changes in physiological and psychological health measures. A total of six participants, with a mean age of 41.2 (range 33-50 years), completed the ten-week study and the six-week intervention. The full study consisted of a four-week control/baseline and a six-week intervention period in which each participant acted as their own controls. Continuous measures of physical activity data were collected using a wrist-worn activity sensor during the ten-week study, along with pre- and post-measures of cardiovascular fitness, upper-body strength, BMI, general health, and motivation to exercise. The intervention consisted of a resistance-training programme for an outdoor gym and three motivational interviewing sessions. Effect sizes (percentage) for changes pre- to post-training were calculated. The results, because of the small sample size, are presented as individual cases, but the group, as a whole, showed average increases from baseline (pre-) to post-measures in strength (maximum row; 15.33%), time to exhaustion (3.58%), number of steps per day (4%), and autonomous motivation (12%) and average decreases in body weight (-1.08%), fat percentage (-7.58%), strength (chest; -2.5%), and stress symptoms (-2.17%). The six-week intervention programme showed promising results regarding physical activity changes. This study contributes to the limited evidence of the impact of resistance training programmes using outdoor gyms, electronic tracker, and motivational interviewing on physical activity outcomes. © 2019 by the authors.

Perceived challenges during participation in a six month outdoor gym exercise programme : participants reflections
- 2019
-
In: Abstract book. ; , s. 62-62
-
Conference paper (peer-reviewed)abstract
- Background and objective: Research has demonstrated positive associations between park-based outdoor gyms and physical activity (Rung et al., 2011). Few studies have evaluated potential challenges with outdoor gyms on physical activity, especially interventions using smartphone Apps (Johnson et al., 2019). The purpose was to study the participant’s perceived challenges during participation in a six-month outdoor gym program.Methods: Ten participants (age = 50.3, SD = 9.2), with low levels of physical activity were interviewed at the end of the six-month intervention (male = 2; female =8). At the start of the intervention participants received a smartwatch and the “ParkStark” exercise app, along with an individual motivational interviewing coaching sessions.Results/findings: A thematic content analysis of the interview data generated three core themes of perceived challenges experienced during the intervention: negative life event stressors, problems managing the smartwatch and an exercise app, and, lack of motivation. The results indicated both structural and personal challenges, likely to have a negative effect on the adherence to the intervention protocol.Conclusions: It is important to develop simple and user-friendly communication systems. When designing outdoor gyms, it is recommended to organize opportunity for continuous communication with significant others to facilitate motivation and adherence for sustainable exercise.

Challenges for Intervention Research in Health and Lifestyle Research – A Systematic Meta-literature Review
- 2015
-
Conference paper (peer-reviewed)abstract
- IntroductionHealth and well-being are two concepts that are widely discussed within today’s society. A major perspective in health and lifestyle research is to investigate what determinants are associated with health. When it comes to the delivery of health interventions several different approaches have been suggested.MethodsThe meta-synthesis was chosen for synthesis of research studies using a health and lifestyle the review format and analyse meta-questions. The process included the following five phases:1. Literature search for articles.2. Selection of relevant articles after repeated reading and appraisal of the articles.3. Extraction of data from each article and creating a list of findings as key phrases, ideas and concepts for each individual study.4. Determining how the findings of the selected studies are related and translating findings into one another.5. Synthesizing the translations to produce a new theoretical interpretation.ResultsThe search yielded a total of 561 unique citations and finally 24 citations remained. Of those 11 studies focused on health determinants, while 13 focused on interventions for health promotion. The meta-synthesis led to four recommendations for the design of future intervention studies. (1) scientific disciplines should collaborate in the design, implementation and evaluation of the study. (2) to use theoretical frameworks that focus on health determinants and to apply longitudinal studies with a repeated measures design.(3) involve behavioral interventions. (4) to design face-to-face intervention studies.DiscussionDeterminants was related to a physical active lifestyle, more specifically high quality school programs for physical education. It could be a starting point for a nationwide approach of daily physical activity in whole society. In all intervention studies physical activity behaviors were included as outcome or intervention program. It is therefore speculated that physical activity behavior could be discussed as one mediator between health determinants and health outcomes.ReferencesBailey, R. (2006).

Journal article (peer-reviewed)abstract
- The overall aim of this systematic meta-literature review was to (1) summarize the findings of review studies focusing on health determinants, (2) give an overview of intervention studies that have been used to facilitate health and lifestyle, and (3) provide recommendations for future studies in health promotion. A literature review, using a meta-method, was conducted to identify health and lifestyle research based on research articles related to health changes. The search yielded a total of 561 unique citations and finally 24 citations remained. Of those, 11 studies focused on health determinants, whereas 13 focused on interventions for health promotion. Results from this meta-synthesis led to four recommendations for the design of future intervention studies. (1) To increase the likelihood of capturing different biopsychosocial aspects of health, researchers from different scientific disciplines should collaborate in the design, implementation, and evaluation of the study. (2) It is recommended to use theoretical frameworks that focus on health determinants in longitudinal studies with a repeated measures design. (3) Studies should involve behavioral interventions. (4) Design face-to-face intervention studies where the participant can interact with other persons.

Dual Career Balance in Student-Athletes University Transition
- 2016
-
Conference paper (peer-reviewed)abstract
- Balancing studies, a personal life and sports, that is, having a dual career, is considered as a challenge associated with transitional demands in athletic and non-athletic (psychological, psychosocial, academic/vocational, financial) domains (Wylleman, Reints, & De Knop, 2013). The aim of this study was to investigate student-athletes’ university transition with a specific focus on how student-athletes balance different domains of their lives. Twenty-three Swedish university student-athletes (mean age= 21.52; 16 males and 7 females) representing six sports (equestrianism, golf, handball, ice hockey, soccer, table tennis) partook in the study. Participants completed the Dual Career Monitoring Survey (DCMS), weekly, over the first twelve weeks of their university education. The DCMS is developed by the authors and measures student-athletes perceptions of balance, time investments, demands, coping, satisfaction, resources and barriers in relation to sport, studies, private life, social life and financial situation. In exploring student-athletes’ perception of dual career balance throughout the twelve weeks, an intra-class correlation analysis revealed a between-person variance of 0.14 (14%). That is, with regards to balance in their dual careers 86% was due to within-person variance, suggesting that balance is idiosyncratic and that further analysis should investigate within-person change. Encouraged by these findings we continued with a person-centered analysis using the Dynamic P-technique for modeling patterns of data (Nelson, Aylward, & Rausch, 2011). The relationships between changes in balance (i.e., prioritizing sport, studies or other domains of life), demands, coping and satisfaction throughout the twelve weeks will be presented. Our findings contribute to the understanding of balance as a central tenet of athletes’ dual careers (Second author et al., 2015). From our findings we suggest practitioners to take into account the individual dynamics in dual career balance from a whole-person perspective.

A multi-disciplinary approach to studying performance among high-level golfers : physiological and biomechanical aspects

-
Licentiate thesis (other academic/artistic)abstract
- In competitive golf, the player’s ability to hit the ball a long distance affects the score in a positive way. Swing kinematics is considered an important factor in driver performance; one way of improving swing kinematics is through strength and power training. Subsequently, high-level golfers and their coaches often explore novel ways of increasing the distance of a shot, in particular driver carry distance (CD). This licentiate thesis presents two studies with the overall aim of studying how swing kinematic and physical characteristics are associated with driver performance among intercollegiate golf players. The studies report swing kinematics associated with driver performance (study 1) and the impact of isokinetic rotational training on driver performance and swing kinematic variables (study 2).The methods used were (1) a cross-sectional correlation study (n=15) and (2) an open trial intervention study (n=20). The studies investigated (1) the relationship between golf swing kinematics and driver performance, and (2) the impact of strength training on swing kinematics and driver performance variable.The results show variables that were distinctive for the club head speed (CHS) were mainly during the downswing: greater X-factor stretch; and higher pelvis peak speed. Whilst, factors distinctive to the regression model for CD were mainly at impact: reduced thorax rotation; and greater thorax lateral bend. Nine weeks of isokinetic training increased seated rotational force and power, peak arm speed and arm acceleration, ball speed, and CD more compared to isotonic training. Even though isokinetic training did not increase CHS, it did result in greater CD.This licentiate thesis contributes to the understanding of which variables influence driver performance, in particular CD, among high-level golfers. Segmental interactions (pelvis-thorax), lead arm speed and acceleration, isokinetic and isotonic training. These results may guide training interventions aiming to improve driver and golf performance among high-level golfers, particularly those with a background of strength training. Future studies could investigate how the interaction between swing kinematics, clubhead trajectory, and driver performance variables differ between male and female golfers.

Conference paper (peer-reviewed)abstract
- Introduction: Assessing the isoinertial force-velocity (F-V) and power relationships has previously been found valuable to assist the understanding of the underlying mechanisms responsible for maximal power output. Multiple studies have investigated the F-V profile in the lower body, however, few studies have investigated F-V profiling in rotational movements, in particular, the golf swing. There is a need for isoinertial strength assessment protocols which can relate to final swing performance. The specific objective of the study was to investigate if measurements of force, velocity, and power using five different loads in a golf specific rotational movement are valid and reliable. Methods: 12 elite golfers (handicap -1.5±1.2) 8 men and 4 women performed a golf relevant rotational movement using five different loads (2, 6, 10, 14, and18 kg) in a motorised cable machine (1080 Motion AB, Sweden), measuring exercise peak force (PF), peak velocity (PV), and peak power (PP). In addition, normal-swing driver clubhead speed (CHSnor), and maximum clubhead speed (CHSmax) was measured using radar (Trackman, Denmark). The best of three trials for CHSnor, CHSmax, and the golf rotation was used for further analysis. Test-retest occasions were separated by 7-14 days. Statistical analysis: Change in mean (CIM) individual inter-session coefficient of variation (CV) and intraclass correlation coefficient (ICC) was used to analyze test-retest reliability, a Spearman's correlation between the rotation output variables and the CHS was used to assess construct validity.For reliability, an ICC of >0.70 was considered acceptable and results for correlation was considered excellent (≥0.90), good (0.75–0.89), moderate (0.50–0.74), poor (<0.50).was considered to be acceptable. Results: PF, PV, and PP for all of the five loads, apart from PP with 2 kg (CIM=12.2%, CV=14.1%, &ICC= 0.29) and PP with 18kg (CIM=8.6%, CV=19.1%, & ICC= 0.93), showed good reliability (CIM= 0.05-3.6%, CV=1.4-8.5%, & ICC= 0.84-0.97). PF (r=0.780-0.89 & 0.75-0.88), PV (r=0.76-0.86 & 0.78-0.85), and PP (r=0.75-0.84 & 0.76-0.85) for all loads had statistically significant strong correlations with both CHSnor and CHSmax respectively, apart from PF at 2kg (r=0.33). The average day to day variation among all loads for PF, PV and PP were 17.9 ±13.7 N, 0.30 ± 0.23 m/s, and 135.9 ± 128.1 W respectively. Greatest PP was achieved with the 14 kg load, although PP at 6, 10, and 14kg only differed by 90 W (8%) between these loads. Discussion: Isoinertial force-velocity-power profiling in high-level golfers can be assessed after a familiarization session. The strongest correlation among the rotational tests and CHS was between PF at 10 kg and CHSnor (r=0.89) and in general, the PF, PV, and PP variables had a strong relationship with both CHSnor and CHSmax. Such profiling may provide valuable information insight into the neuromuscular capabilities of high-level golfers and may be used to monitor specific training adaptions.

Effects of 8 Weeks of Isokinetic Training on Power, Golf Kinematics, and Club Head Speed In Elite Golfers
- 2015
-
Conference paper (other academic/artistic)abstract
- Introduction: Elite competitive golfers commonly use physical conditioning as a way of improving playing results. Multiple studies have investigated the use of different training methods for improving performance but few studies have investigated the use of isokinetic power training as a way of improving swing kinematics and/or club head speed (CHS). The specific objective of the study was to investigate if eight weeks of isokinetic power training was more effective than traditional power training in improving swing kinematics and CHS.Methods: 20 competitive elite golfers (handicap better than -3.1), 13 men and 7 women, (age 22±2 years) were tested for lower body power (countermovement jump and loaded vertical squat jump 20,40 & 60kg), rotational power (seated upper body rotational power at 10% of body weight; bw) and golf swing kinematics (pelvis, thorax and lead arm peak rotational velocities using electromagnetic motion capture system; Polhemus Inc. USA ) and club head speed (doppler-radar launch monitor system; Flightscope, South Africa), Participants were split into a control (CTL) group (n=10) who continued with the regular strength and power training and an intervention (IK) group (n=10) performing isokinetic power training in the isokinetic 1080Quantum system (1080Motion, Sweden) during 8 weeks. The intervention focused on barbell squat (22kg at 0.5 ms-1) and standing rotation (10% body weight at 1 ms-1).Statistical analysis: a 2 (between; groups) x 2 (within; time) ANOVA assessed any differences in power, club and swing kinematics.Results: Statistically significant improvements were observed in both the IK and CTL group for rotational power (p<0.001), CHS (p=0.025), and peak arm speed (p=0.001). There were no significant differences in countermovement jump height, peak power during squats, peak pelvis speed, or peak thorax speed following the intervention period.Discussion: After 8 weeks of power training, both rotational power and peak arm speed improved as did the performance measure of CHS in both the IK and CTL group. However no significant changes were found between the two groups. In conclusion, there was no evidence suggesting that isokinetic training, as performed in this study, is neither detrimental, nor more effective, than traditional strength training when it comes to increasing CHS in golf performance.

Journal article (peer-reviewed)abstract
- BackgroundIt has previously been shown that isotonic strength training can improve driver performance among golfers, though few studies have investigated effects of strength training on swing kinematics together with driver performance. In this study we investigated whether isokinetic rotational training could improve driver performance and swing kinematic variables amongst elite golfers.MethodsTwenty competitive pre-elite golfers (handicap better than −3.0), 13 men and 7 women, were split into two groups, one group received the isokinetic power training (IK) alongside their normal isotonic pre-season strength-training and the other group continued with their normal isotonic pre-season strength-training regime (IT). The IK group completed 12 sessions of isokinetic power training on a standing rotation exercise (10% body weight at 1 m/s) and barbell squat (25 kg plus 10% body weight at 0.5 m/s). The IT group continued with their normal isotonic pre-season strength-training regime. Participants were tested for rotational power, lower body power, golf swing kinematics, and driver performance before and after a nine-week training period.ResultsAfter the nine-week training period both the IK and the IT groups increased their dominant side rotational force and power (effect sizes between 0.50–0.96) and magnitude based inference indicated that IK had a likely (> 80%) more beneficial increase in dominant side rotational force and power. For swing kinematics, IK had a likely (> 80%) more beneficial improvement in lead arm speed and acceleration compared to the IT group. For driver performance, IK had a possible (65%) beneficial effect on ball speed and likely (78%) beneficial effect on carry distance when compared to IT, whereas neither of the groups improved club head speed.ConclusionIn the present study on pre-elite golfers we found that 9 weeks of isokinetic training increased seated rotational force and power, peak arm speed and arm acceleration, ball speed, and carry distance more compared to isotonic training. Even though isokinetic training did not increase CHS, it did result in greater carry distance. © The Author(s). 2017
