ESTIMATES OF GLOBAL DIABETES PREVALENCE and most recent
projections for the future indicate that diabetes now affects 246
million people worldwide and is expected to affect some 380
million by 2025, representing as much as 7.1% of the global
adult population (58). The increase in Type 2 diabetes prevalence can only partly be attributed to the changing population
demographics, since epidemiological data show diabetes prevalence to increase progressively in young and middle-aged
people (2). The latter implies that, in the near future, Type 2
diabetes-related complications, like nephropathy, retinopathy,
neuropathy, myocardial infarction, stroke, and even death, will
be experienced more frequently and at a much earlier age (94).
The greater incidence and prevalence of overt clinical complications in a vastly expanding diabetes population will impose
an enormous burden on our healthcare system and on the
quality of life of the Type 2 diabetes patient (2, 16). Much
effort is currently put into the discovery of novel pharmacological solutions that might improve metabolic control and
prevent diabetes-related comorbidities. Although intense blood
pressure and blood glucose-lowering therapy has been shown
to reduce (microvascular) complications in Type 2 diabetes
(120, 124), enhanced glycemic control with either sulphonylureas, glitazones, or exogenous insulin therapy does not necessarily prevent the number of cardiovascular events (87, 124).

Apparently, further reductions in glycosylated hemoglobin
(HbA1c) levels and blood pressure are needed to improve
long-term cardiovascular outcome. The Steno-2 study provides
good evidence that this can only be achieved through multifactorial intervention, consisting of both well-structured lifestyle and pharmaceutical measures (46). Also, in populations at
risk for developing Type 2 diabetes, it is now well established
that increased physical activity levels and long-term weight
loss reduce the prevalence of metabolic syndrome (49, 63, 90)
and prevent or delay the progression toward Type 2 diabetes
(67, 73, 91). In accordance, lifestyle intervention programs
consisting of regular exercise with (35, 73) or without (35, 122,
128) dietary modulation and/or oral blood glucose-lowering
medication (11, 65) have proven an effective therapeutic strategy in Type 2 diabetes. As such, the current increase in Type
2 diabetes incidence and concomitant cardiovascular comorbidities can only be reversed by dramatic lifestyle changes.
Current guidelines from the American Diabetes Association
(ADA), the European Association for the Study of Diabetes
(EASD), or the American College of Physicians (ACP) all
firmly recognize the therapeutic strength of exercise intervention (5, 84, 114). The ADA states that “to improve glycemic
control, assist with weight maintenance, and reduce risk of
cardiovascular disease, at least 150 min/week of moderateintensity aerobic physical activity is recommended and/or at
least 90 min/week of vigorous aerobic exercise . . . distributed
over at least 3 days/week and with no more than 2 consecutive
days without physical activity” (5). Since 2006, the ADA

doi:10.1152/japplphysiol.00566.2007.—Other than diet and medication, exercise is
considered one of the three cornerstones of good diabetes treatment. Nevertheless,
current clinical guidelines on Type 2 diabetes provide no detailed information on
the modalities of effective exercise intervention in the treatment of Type 2 diabetes.
Based on a review of currently available literature, exercise modalities are being
identified to maximize the benefits of exercise intervention in the treatment of
different Type 2 diabetes subpopulations. Both endurance and resistance types of
exercise have equal therapeutic strength to improve metabolic control in patients
with Type 2 diabetes. When applying endurance-type exercise, energy expenditure
should be equivalent to ⬃1.7–2.1 MJ/exercise bout on 3 but preferably 5 days/wk.
In sarcopenic or severely deconditioned patients with Type 2 diabetes, focus should
lie on the implementation of resistance-type exercise to attenuate and/or reverse the
decline in skeletal muscle mass and strength. Before choosing the most appropriate
exercise modalities, the patient’s disease stage should be well characterized, and an
ECG-stress test should be considered. Based on baseline aerobic fitness, level of
co-morbidities, body composition, and muscle strength, patients should be provided
with an individually tailored exercise intervention program to optimize therapeutic
value. A multidisciplinary individualized approach and continued exercise training
under personal supervision is essential to enhance compliance and allow long-term
health benefits of an exercise intervention program.

EXERCISE AND TYPE 2 DIABETES
guidelines explicitly mention and recognize that “in the absence of contraindications, people with type 2 diabetes should
be encouraged to perform resistance exercise 3 times a week,
targeting all major muscle groups, progressing to 3 sets of
8 –10 repetitions at a weight that cannot be lifted more than
8 –10 times” (114). However, these clinical guidelines generally do not include detailed information on the preferred type
and intensity of exercise that should be applied to maximize the
benefits of exercise for different subgroups of patients with
Type 2 diabetes.
More than 20 years ago, it was already reported that there
is an urgent need to define the characteristics of appropriate
exercise prescription in chronic metabolic disease (106). The
present review aims to identify the exercise modalities that
define an effective interventional strategy in the treatment of
different Type 2 diabetes subpopulations.
RESISTANCE- VS. ENDURANCE-TYPE EXERCISE
J Appl Physiol • VOL
INTENSITY VS. DURATION OF EXERCISE
Clinical practice guidelines on the application of exercise
intervention in Type 2 diabetes do not provide much detail
regarding the duration and/or intensity of exercise that should
be applied to maximize subsequent health benefits for different
subpopulations (5, 57). As exercise intensity is increased,
muscle glycogen becomes a more important substrate source
(61). The depletion of muscle glycogen stores and subsequent
postexercise muscle glycogen resynthesis is coupled to the
postexercise improvement in glucose tolerance and/or insulin
sensitivity (48, 126). Therefore, when considering the more
acute glucoregulatory effects of exercise, higher exercise intensities should theoretically be more effective to stimulate
insulin sensitivity and improve glucose homeostasis. However,
data from a limited number of studies (32, 66, 71, 72, 127) are
inconclusive, and several factors, such as release of counterregulatory hormones (66), training status (64), and exercise
performed either in the postabsorptive (66) or postprandial
state (72), may explain these contradictory findings. Nevertheless, the energy equivalent of the exercise bout appears to
represent the major determinant of the exercise-induced
changes in glucose homeostasis (71, 72). Therefore, a lesser
exercise intensity should be compensated for by an increase in
exercise duration.
Although less evident for resistance-type exercise, energy
expenditure for endurance type exercise can be estimated by
using metabolic equivalent tables (1). Endurance-type exercise
programs should entail at least 3 exercise sessions/wk in which
the energy equivalent of each exercise bout should represent
⬃1.7 MJ (⬇400 kcal), or rather 4 –5 sessions/wk with an
energy equivalent of ⬃2.1 MJ (⬇500 kcal) per exercise bout
(52, 56, 88). In the average overweight/obese patient with
uncomplicated Type 2 diabetes, this minimum of 5 MJ/wk
(⬇1,200 kcal) would be equivalent to a minimum of 170 –200
min or ⬃19 km of brisk walking per week (20, 59, 115).
When applying resistance-type exercise, strength improvements tend to follow a linear dose-response relationship, at
least in healthy subjects (47, 98). If the therapeutic aim of
resistance-type exercise is to stimulate muscle glycogen storage depletion and net muscle mass gain, both exercise intensity

Both a single bout of endurance- (31) as well as resistancetype exercise (43, 101) have been shown to improve whole
body insulin sensitivity and/or oral glucose tolerance. Therefore, both types of exercise are of therapeutic use in an
insulin-resistant state (116). The acute effects of exercise on
skeletal muscle insulin sensitivity are attributed to the prolonged activation of the skeletal muscle glucose transporter
system (48), depletion of muscle and liver glycogen stores (96,
103), and/or increased skeletal muscle blood flow following
the cessation of exercise (13). The glucoregulatory benefits of
either type of exercise training is represented by the sum of the
effects of each successive bout of exercise. In addition, more
prolonged exercise training is accompanied by a more structural adaptive response. Apparent differences exist in the
long-term adaptive response to endurance- or resistance-type
exercise training. Prolonged endurance-type exercise training
has been shown to improve insulin sensitivity in both young
(28), elderly (60), and/or insulin-resistant subjects (27, 29, 97,
107). The latter is attributed to the concomitant induction of
weight loss, the upregulation of skeletal muscle GLUT4 expression, improved nitric oxide-mediated skeletal muscle
blood flow (76), reduced hormonal stimulation of hepatic
glucose production (112), and the normalization of blood lipid
profiles (17). Long-term resistance-type exercise interventions
have also been reported to improve glucose tolerance and/or
whole body insulin sensitivity (33, 43, 54). Other than the
consecutive effects of each successive bout of exercise, resistance-type exercise training has been associated with a substantial gain in skeletal muscle mass, thereby improving whole
body glucose-disposal capacity (43). Besides the attenuation of
the loss of muscle mass with aging, resistance-type exercise
training also improves muscle strength and functional capacity,
thereby allowing a healthier, more active lifestyle. Some studies report even greater benefits of resistance- as opposed to
endurance-type exercise training on glycemic control and insulin sensitivity in long-standing patients with Type 2 diabetes
(19). As such, it has been firmly established that both endurance- and resistance-type exercise training can be applied to
improve metabolic control and quality of life in patients with
Type 2 diabetes (116).
In most lifestyle intervention programs, the focus generally
lies on the implementation of endurance-type exercise activity.
The latter can be explained by the fact that endurance-type
exercise has been known for its efficacy to reduce body fat
mass and its subsequent effects on whole body insulin sensitivity. Since many patients with Type 2 diabetes suffer from
muscle weakness (6, 108, 129), cardiovascular comorbidities
(117, 130), and reduced exercise tolerance (42), it has been
proven difficult to engage patients with Type 2 diabetes into
adhering to strict endurance-type exercise intervention programs (34, 111). Alternatively, endurance-type exercise combined with resistance (i.e., intermittent intensity-type exercise)
forms a lower cardiovascular challenge (81) and improves
functional performance capacity to a similar extent (79).
Therefore, the combination of endurance- and resistance-type
exercise is preferred since it augments the diversity and, as
such, the adherence to the exercise intervention program. To
maximize the benefits of exercise intervention, the emphasis to
apply either more endurance- or more resistance-type exercise
should be tailored to the level of comorbidity present in a
specific diabetes subpopulation (see below).
Invited Review
EXERCISE AND TYPE 2 DIABETES
FREQUENCY AND TIMING OF EXERCISE
The enhanced insulin sensitivity following an acute bout of
exercise has been reported to persist for a period ranging from
2 (83), 4 – 6 (132), 12–16 (31, 89), 24 (24, 110), and to up to
48 h following the cessation of exercise (83). As such, the
benefits of exercise on glycemic control can largely be attributed to the cumulative effects of each successive bout of
endurance- or resistance-type exercise rather than the structural
adaptive response to prolonged exercise training (110). In fact,
long-term training effects on glycemic control may be lost
entirely 6 –14 days after cessation of training (27, 53). Therefore, it is preferred to perform exercise everyday. The ACP
guidelines prescribe an exercise frequency of at least three
times per week with no more than 2 consecutive days without
physical activity (4). Indeed, the ADA (5) now recognizes that
these guidelines need to be considered a minimal therapeutic
dosis and, therefore, a less than optimal therapy.
Furthermore, current guidelines on exercise prescription as
therapeutic strategy (3, 5) do not consider an optimal timing of
a daily exercise routine. In this respect, it is interesting to note
that, in patients with Type 2 diabetes, hyperglycemic episodes
during the day are most predominant in the morning in the
postprandial state (51, 102). This so-called “dawn-phenomenon” (15) seems to be related to the diurnal variation in
endogenous glucose production (104). Since moderate-intensity exercise suppresses endogenous glucose production, it
might be advantageous to schedule moderate-intensity endurance exercise sessions in the morning, preferably in the postprandial state. More research is warranted to assess the impact
of timing of exercise and nutrition on daily hyperglycemia in
patients with Type 2 diabetes (71, 101).
STAGE OF DISEASE AND COMORBIDITY
The prolonged application of either endurance or a combination of resistance- and endurance-type exercise training has
J Appl Physiol • VOL
been shown to increase whole body glucose tolerance and/or
insulin sensitivity (56) and can prevent the development of
Type 2 diabetes (67, 123). The implementation of resistanceand endurance-type exercise improves glycemic control (11,
74, 75, 121), blood pressure (11, 74), body composition (11,
23, 74), and blood lipid profile (11, 75). Furthermore, exercise
training has been reported to modify the progression of peripheral neuropathy (10) and attenuates the progressive increase in
blood glucose-lowering medication requirements (11). However, when implementing endurance- and resistance-type exercise intervention in the treatment of Type 2 diabetes, we also
need to consider the stage of the disease, body composition,
and the presence of comorbidities. In recently diagnosed, obese
patients with Type 2 diabetes, the main therapeutic target of
lifestyle intervention should be a durable reduction in fat mass
and a concomitant improvement in aerobic fitness and whole
body insulin sensitivity (5), a conclusion well in line with
exercise recommendations for normoglycemic obese subjects
(50). As such, obese patients with Type 2 diabetes would
benefit most from a program mainly consisting of moderateintensity endurance exercise, aiming for an energy expenditure
of at least 5 MJ (⬇1,200 kcal) (56, 88) but preferably ⬎8.4 MJ
(⬇2,000 kcal) per week (52). In these patients, endurance-type
exercise should be combined with dietary restriction (14, 62,
133). To prevent the loss of lean body mass due to the energy
intake restriction, at least one resistance exercise session
should be included per week (25).
Another expanding Type 2 diabetes subpopulation is formed
by the long-standing, insulin-treated patients with Type 2
diabetes (30). These patients generally suffer from severe
exercise intolerance due to low oxidative capacity (42), neuropathy-related muscle weakness (6, 100, 108, 129), sarcopenia
(18), and/or micro- and macrovascular disease (37, 100). Since
generic exercise intervention programs are too demanding for
most of these patients, it is of utmost importance to implement
intermediate exercise intervention programs. Such intermediate programs are needed to bring patients to a level at which
they are able to participate in more generic diabetes intervention programs. Such intermediate programs should implement
short, relatively high-intensity exercise bouts applied in an
intermittent fashion with the intention to increase muscle
strength and functional performance. These so-called short
“in-and-out” exercises do not produce feelings of dyspnea or
discomfort and have been proven safe and effective in cardiac
(79, 80) and insulin-treated patients with Type 2 diabetes (101)
with a high-cardiovascular risk profile. The efficacy of such
intermediate programs remains to be established, since exercise intervention studies have generally excluded long-standing, insulin-treated patients with Type 2 diabetes.
Another vastly expanding diabetes subgroup is formed by
the elderly (⬎70 yr) patients with Type 2 diabetes. Aging is
associated with the loss of skeletal muscle mass and represents
one of the main factors responsible for the increase in Type 2
diabetes incidence at an advancing age (95). The loss of muscle
mass is proportionally related to the reduction in blood glucose
disposal capacity and the decline in muscle strength (92). The
latter prevents many elderly diabetes patients from participating in lifestyle intervention programs. Although even lowimpact endurance-type exercise has been reported to improve
glycemic control in elderly patients with Type 2 diabetes (70,
121), it has been suggested that the insulin-sensitizing response
103 • OCTOBER 2007 •

and volume should be kept high (21, 68). However, studies
assessing the impact of exercise intensity in resistance-type
exercise interventions in patients with Type 2 diabetes
remain lacking. It has been established that progressively
intensified moderate- to high-impact resistance training over
a period of 6 wk (3 ⫻ 30 min exercise/wk) upregulates the
activity of key proteins in the insulin-signaling cascade,
resulting in enhanced insulin-stimulated blood glucose disposal in muscle (54). In accordance, resistance-type exercise
training has been shown to reduce blood HbA1c levels with
0.4 – 0.8% in patients with Type 2 diabetes (116). Until more
information becomes available, it is advised to implement
resistance-type exercise training with exercise volume and
intensity being progressively increased toward three sets of
8 –10 repetitions performed at 70 – 80% of 1 repetition
maximum per muscle group (114).
Many patients with Type 2 diabetes experience some musculoskeletal (6, 100, 108, 129) and/or cardiorespiratory deconditioning (42). Therefore, exercise intensity, duration,
and volume should be gradually increased over a period of
6 –12 wk. In addition, endurance- and resistance-type exercise of the same muscle group on the same day should be
avoided to reduce the risk of overuse injuries and subsequent dropout.

to exercise is attenuated with an advancing age (82, 113). Since
Type 2 diabetes patients show an accelerated decline in muscle
mass and strength with aging (93), it would be preferable to
focus more on increasing skeletal muscle mass and strength
when designing exercise intervention programs for the elderly
patients with Type 2 diabetes (26, 131). Effective exercise
intervention programs for the elderly patient with Type 2
diabetes should include resistance-type exercise, with exercise
volume and intensity being progressively increased toward
three sets of 8 –10 repetitions with intensities ranging from 50
to 80% 1 repetition maximum for 7–10 exercises and/or muscle
groups (9, 33, 43, 55). Dietary cointerventions might further
improve the benefits of resistance-type exercise training in
elderly patients (38, 69).
Furthermore, when prescribing exercise intervention in patients with Type 2 diabetes, it should be noted that long-term
adherence to an exercise intervention program may vary
with the presence of comorbidities, the level of deconditioning,
and/or orthopedic limitations (7, 92). Therefore, a multidisciplinary team should consider the level of impaired exercise tolerance and individualize the exercise intervention
program to prevent dropout and empower the patient to
adhere to such lifestyle changes (34, 73, 111).

SAFETY ASPECTS
Before exposing patients with Type 2 diabetes to more
vigorous exercise programs, the ADA and US Preventive
Services Task Force recommend exercise testing for silent
myocardial ischemia (SMI) if 10 years’ cardiovascular risk
exceeds 10% (45, 114). Cardiac dysfunction (41) and SMI are
estimated to be present between 6 and 22% (130) of the
patients with Type 2 diabetes, with cardiac autonomic dysfunction, disease duration, and male gender being the best predictors for SMI (130). Moreover, poor physical fitness (78),
scintigraphy abnormalities (39), diabetic retinopathy (39), and
an advancing age ⬎60 yr (125) in combination with the
traditional cardiac risk factors also represent good predictors
for the likelihood of a cardiac event. The UKPDS Risk Engine
version 2.0 (available free of charge at http://www.dtu.ox.
ac.uk/) can be of help to calculate an individual patient’s risk
for coronary heart disease (118). Although arbitrary, the
UKPDS Risk Engine indicates that ECG stress testing in Type
2 diabetes is useful in most patients with ⬎2 cardiovascular
risk factors, in middle-aged patients with a diabetes duration
⬎5 yr, as well in elderly patients ⬎70 yr of age. Although a
stress ECG is not the most sensitive diagnostic tool to detect

SMI (86) and predict coronary events (85), it is still the most
cost effective when trying to minimize the risk of a coronary
event (22). In case SMI is expected, more sensitive diagnostic
tests such as myocardial perfusion scintigraphy (12), electron
beam computerized tomography (109), and/or coronary angiography (8) should be considered before more vigorous
exercise is prescribed. Even in the absence of SMI, a stress test
will detect chronotropic incompetence (36) as well as exerciserelated hypertension and provide more objective information
on the individual fitness level (42). This information should be
used to further tailor an exercise program for the individual
(Fig. 1).

In the present review, we have identified the modalities of
effective exercise intervention in the treatment of Type 2
diabetes. Before choosing the most appropriate exercise modalities, the patient’s disease stage should be well characterized, and an ECG-stress test should be considered. Based on
baseline aerobic fitness, level of comorbidities, appendicular
skeletal muscle mass, and strength, patients should be provided
with a fitting exercise intervention program to optimize its
therapeutic value. Recently diagnosed obese patients with
Type 2 diabetes will benefit most from daily, intense moderateintensity endurance training in combination with energy intake
restriction. The latter should be combined with at least one
resistance-type exercise session per week to prevent the loss of
fat-free mass. Long-standing, insulin-treated patients with
Type 2 diabetes, in whom comorbidities generally prevail,
should be prescribed with an exercise program containing
intermittent, relatively high-intensity resistance- and endurance-type exercise. After substantial improvement in muscle
strength and functional performance, more generic exercise
intervention programs (with more intense endurance-type exercise training) should be considered. In an expanding population of elderly onset patients with Type 2 diabetes, focus
should lie on the implementation of resistance-type exercise to
attenuate and/or reverse the decline in skeletal muscle mass
and strength. When applying endurance-type exercise, energy
expenditure should be equivalent to ⬃1.7–2.1 MJ (⬇400 –500
kcal) per exercise bout on 3 but preferably 4 –5 days/wk, since
many of the benefits of exercise are temporarily. More vigorous exercise in uncomplicated insulin-resistant states will further improve glycemic control and enhance cardiorespiratory
fitness and microvascular function. Most patients with Type 2
diabetes find it difficult to adhere to structural exercise intervention programs. Compliance to an exercise intervention
program can be enhanced by a multidisciplinary approach and
continued exercise training under strict personal supervision.
