Abstract — Several studies have shown that mindfulness-based
interventions in clinical settings can elicit positive outcome such as:reducing anxiety or increasing psychological well-being, which could
be beneficial to the sport experience too. Evidence of mindfulness
applied to the sport and physical activity context has not been yetsystematically reviewed. A literature research was undertaken using
PsycInfo, Medline, Science direct, ISI web of Knowledge & Ovid
databases, reviewing afterwards the references of the retrievedarticles. Seven out of the 52 studies, dated between 2000 and 2010
and related to mindfulness and sport, exercise or physical activity,were analyzed. Research outcomes included high correlations
between mindfulness and flow state, suggesting that the more
mindful individuals are, the more likely to experience flow states.Mindfulness-based interventions and mindfulness high score
measures had no effect on sport performance improvement. However,they may be effective in enhancing psychological well-being, directly
related to the sport performance.
Keywords — Mindfulness, psychological well-being, sport
performance, systematic review.
I. I NTRODUCTION
URING competitive sport activities, athletes must be
mentally ready to perform under stressful
circumstances. The construct of mindfulness has been
considered, in the sport psychology field, in order to
understand the mental states during sport practice and to
develop effective tools to enhance performance. Mindfulness,
defined as the non-judgmental focus of one’s attention on the
experience that occurs at the present moment [1], could help
address issues related to the tendencies of focusing on the
present moment in sport activities, like the flow state
consctruct does [2], [3]. Mindfulness has been suggested to
represent the non-judgmental observation of the ongoing
stream of internal and external stimuli [4]. Brown and Ryan
[5] have shown that mindfulness is a distinct form of
awareness and attention, which could be considered a
predisposition for well-being enhancement.Several studies have shown that mindfulness-based
interventions in clinical context could benefit people suffering
from chronic pain, fibromyalgia, cancer, heart disease and
anxiety [6]. These interventions could also afford positive
outcomes as acceptance of negative thoughts, reduce
worrying, and increase enjoyment, concentration and
persistence [7].

Mindfulness-based interventions are, thus, presented as
effective elements to overcome stressful stimuli.
Therefore they could facilitate peak sport performance.
With a heightened self-regulation of attention, those who are
mindful are more likely to be conscious of their goals when
executing moves and will be better at detecting threats and
emotional events [4]. Siegel [8] found out that cultivating
mindful awareness seemed to increase the capacity to regulate
emotions, combat emotional dysfunction, improve thinking
patterns, and reduce negative mindsets, as well as to enhance
bodily functioning and strengthen interpersonal relationships.
Mindfulness encourages awareness of inner states,
including cognitive and somatic phenomena [5]. It should
therefore be a strong mediator of exercise-related variables
and peak performance experiences; although currently there
are little supportive data and a dearth of research involving
mindfulness and attention allocation in the sport context.
II. OBJETIVE
No review has yet covered all available evidence of
mindfulness applied to the sport and physical activity context.
The aim of the present paper is to systematically summarizethe evidence of the presumed benefits of mindfulness in
sports. Main research outcomes are discussed in order to
establish whether mindfulness is a viable new research
approach in sport psychology.
III. METHODOLOGY
A. Literature Research
A literature research was undertaken using PsycInfo,
Medline, Science direct, ISI web of Knowledge & Ovid
databases and references of retrieved articles. This search
included papers published in English from January 2000 to
December 2010. The search terms were combined as follows:
a) mindfulness-sport, b) mindfulness-exercise and c)
mindfulness-physical activity.
B. Selection of Trials
Full text articles, short communications and congress
abstracts indexed by the consulted databases that focused on
the relationship of mindfulness construct and psychological,
physical or performance outcomes in participants of sport,
exercise and physical activity were screened by the reviewers
in order to be considered for inclusion. Included studies hadto: (1) target sports, exercise or physical activity population,

(2) with or without mindfulness intervention program, (3)
provide quantitative data supported by statistical methodology.
Reasons for exclusion were: (1) theoretical studies.
C. Outcome Measures
The main outcome measures considered were: (1)
mindfulness and sport performance, (2) mindfulness and other
psychological measures (e.g. flow, cognitive anxiety), (3) post
intervention mindfulness outcomes.
IV. R ESULTS
A. Search Results
The original search retrieved 4576 papers. Of these, 4524
papers were excluded because their primary focus was not the
research of mindfulness in the sport, exercise or physical
activity context (Fig. 1). A total of 52 papers remained after
the first screening; and 36 were excluded using the duplication
criteria. The inclusion and the exclusion criteria were applied
to the remaining 16 papers, resulting in nine being excluded
and seven included in the present review.

A summary of the included studies with their significant
results is illustrated in Table 1.
Research interventions were carried out through the
Mindfulness Based Cognitive Therapy MBCT [9] and theMindfulness Sport Performance Enhancement MSPE [10].
The sports studied were varied and included individual and
team disciplines. Besides, mindfulness was mainly measured
with the Mindful Attention and Awareness Scale MAAS [5],
Kentucky Inventory of Mindfulness Skills KIMS [11],
Toronto Mindfulness Scale TMS [12] and
Mindfulness/Mindlessness Scale MMS [13]. Following theresults of the reviewed studies, mindfulness intervention
programs and high score measures had no effect on sport
performance improvement. In most of them, mindfulness
interacted with other psychological measures, mainly with the
flow state.
V. DISCUSSION
The aim of the present work was to systematically review
current evidence on mindfulness applied to the sports, exercise
or physical activity context. The sport activities covered in this
review included both team and individual disciplines. Results
showed that individual participants were mostly golf and
archery, suggesting that mindfulness could be present mainly
in disciplines whose performance requirements include: self-
paced, closed skill, a high degree of mental focus and fine
motor movement [10]. Furthermore, in team sports
mindfulness and performance were measured during
individual game situations, such as the free throw in basketball
[26]. It has been suggested that endurance and cyclical sports
as long distance running, where anxiety and worries affect
performance, could also benefit from the mental attitude
mindfulness provide with [27], [28].
A. Mindfulness & Flow
Mindfulness state has been related specially with the flow
construct [10], [30], [29]. Qualitatively, a lack of self-
consciousness appears in both states [24], [31] and
quantitatively, there is a high scores correlation. Flow state
experience could be present in those athletes prone to be
mindful and that state could be promoted during the
mindfulness training. Despite the similarities and correlations
between mindfulness and flow, researches have failed to prove
causality relations.
B. Mindfulness-based Interventions
The Mindfulness Sport Performance Enhancement (MSPE)
intervention has offered mixed results, as a performance
enhancement program has not been effective; however, it has
proved to be a promise as an intervention to enhance flow and
mindfulness: disposition and state [10], [27]. On the contrary,
a Mindfulness-Based Stress Reduction [1] intervention, which
served as a basis for development of MSPE, has shown
efficacy for many psychiatric and physical conditions [6]. In
the sport context, performance enhancement was not reached
after the four week MSPE intervention. In comparison, the
effective MBSR interventions have a length of eight weeks.
Kaufman et al. [10] considered that mindfulness was such a
new skill in sport that it might be difficult for athletes to

improve their performance just with the MSPE length.
Considering that the development of mindfulness ability is
gradual and systematic, requiring regular practice, a 4 week
program might not be enough neither to enhance sport
performance nor to improve mindfulness skills. Nonetheless, it
is not clear the way in which the flow state, which is directlyrelated to sport performance, improves with MSPE. In general
there is not a clear theoretical explanation about how
mindfulness could improve sport performance; although it has
been assumed that the self-regulation of attention related to
mindfulness is an inherent and important quality of peak
performance [26], [31, [33]. If the mindfulness construct is
treated as an inherent state of consciousness, it is suggested
that individuals may differ in the frequency with which they
deploy attention and awareness, and also in the fact that there
are intra individual variations in mindfulness [5]. Mindfulness
may present different advantages for different sports,
depending on the main performance subcomponents (i.e.
physical, technical, and tactical) [29].
C. Mindfulness & other Psychological Processes
The non-judgmentally & fully aware acceptation of
cognitions, emotions and sensations at the present moment
includes several psychological processes. For Bernier et al.
[29] flow, mindfulness and acceptance present a positive link.
These authors suggested that the concept of awareness is some
way close to mindfulness; because in both of them there is a
consideration of the athlete’s necessity to be lucid and aware
of their internal states and external cues. A high mindfulness
experience could be also accompanied by atentional control,emotional control, goal setting and self-talk strategies [30].
Mindfulness could operate as a protection resource or
coping strategy against mental introjections and promoting the
use of other coping strategies by the full aware detection
process. Mindful athletes may be better able to attain the
present moment task, not allowing their internal experiences
(e.g. cognitions, emotions, anxiety) affect them [26], [27], and
so, facilitating the athlete’s ability to respond instead of
reacting to them [28], accepting them instead of fighting
against negative thoughts and unpleasant emotions [29].
Moreover, mindfulness as an internal process is presented as a
strong indicator of happiness in athletes [32]. Nevertheless,
mindfulness experience appears to be a compendium of psychological processes which occur simultaneously and
synchronously. Nonetheless, the studies reviewed do not
provide a conclusive explanation about the psychological
abilities related to mindfulness state. It must be added that the
difficulty to measure a mindful state as it happens -asking
athletes in action whether they are focusing on the present
moment- will inevitably disrupt their attention toward the task
at hand [30]. Theoretically, mindfulness has yet to be
satisfactorily operationalized, being largely limited at the
present time to questionnaire-based assessment instruments
[34]. Furthermore, taking into consideration that there is not a
unified mindfulness concept definition.
VI. CONCLUSION AND R ECOMMENDATIONS
The main research outcomes discussed in this review
suggest that mindfulness state would happen during sport
practice. High mindfulness scores are related to increasing the
opportunities athletes have to experience flow state. However,correlation scores do not offer a clear explanation. Despite the
fact that both constructs may be similar (qualitatively), they
are not equivalent. Contrary to mindfulness state, flow is not
voluntary controlled. Actual evidence does not allow
establishing clearly the mindfulness construct effectiveness as
a new psychology approach to sport performance. However,
the mindfulness construct may provide a suitable
psychological framework to understand the effects of self-
regulation of attention with a passive, non-reactive and non-
judgmental attitude that can promote a better psychological
state during sport performance. Mindfulness in sport may
facilitate self-regulation processes of attention and increase
awareness to better manage intrusive thoughts, disturbing
feelings or negative mood states; although this self-regulation
skill may not have any impact in sport performance. In this
sense, mindfulness, as a psychological construct in sport, may
have possibilities under the scope of enhancing psychological
well-being, not directly related to performance but to other
psychological factors like self stem, arousal level, cognitive
and physical information processing or goal settings; that
could mediate sport performance at last. Further empirical
research is needed, especially by using other measures of
psychological skills to better understand the relationship of
mindfulness with other mental skills in sport (e.g. appraisal,
coping, self stem, attention, self-talk strategies). Incorporating physiological and neurobiological assessment procedures,
already used in clinical mindfulness-based interventions can
provide valuable data.
