Abstract:Introduction: Obesity is associated with a sedentary life style, which has a negative impact on physical fitness.Aim: To investigate physical fitness, physical activity level and time spent sitting in Swedish women before and one year after laparoscopic Roux-en-Y Gastric Bypass surgery (LRYGB).Method: Thirty-seven women (age: 41.2±9.6 years and Body Mass Index (BMI): 42±6.5 kg/m 2 ) were tested before and one year after LRYGB. (BMI: 30.5±5.8 kg/m 2 ). Physical fitness was assessed using the six minute walk test (6MWT), and three muscular endurance and one handgrip test. Physical activity level and sitting time were assessed using the short form of the International Physical Activity Questionnaire (IPAQ).Results: One year after surgery the mean distance walked during 6MWT increased from 532 m to 599 m (p=<0.001) and the muscular endurance was significantly improved (p 0.016), while no statistical significant difference was found in grip force compared to pre-operatively. After surgery, the women walked significantly more minutes/week (p=0.018) and increased their level of moderate (p=0.039) and vigorous (p=0.033) physical activity, but there were no significant differences in sitting time (p=0.206) compared to preoperatively. Conclusions:The physical activity level as well as physical fitness increased while grip strength remained same in Swedish women one year after LRYGB, compared to before surgery. The improved physical fitness and the considerable weight loss are important factors in reducing the risk of developing lifestyle associated diseases and risk of premature death in this group of women. But even if both physical activity and physical fitness increased at group level one year after LRYGB, some individuals still needed to be more physically active and to enhance the physical fitness level. These patients might benefit from physiotherapy to be able to be more physically active.

“…[20][21][22] Weight loss, however, is also accompanied with a loss of absolute muscular strength and sometimes improvement in relative muscular strength. 23 Therefore, one may propose that weight loss induces a gain in relative muscular strength which could lead to improved balance control. We hypothesize that improved balance control following weight loss would be due to improved relative muscular strength (that is, muscular strength is important for balance control in overweight and obese individuals).…”

Weight loss and muscular strength affect static balance control

Objective: Overweight individuals sway more than normal weight individuals. Major weight loss improves their balance control despite a related decrease in muscle strength. Presumably, muscular strength is an important factor for balance control. This study investigated the effect that a change in body mass has on relative strength and balance control. Methodology: Force (isometric knee extension) and balance control (center of pressure speed and range) were studied in three groups; normal weight (BMI o25 kg m À2 ), obese (30 kg m À2 oBMIo 40 kg m À2 ) and excess obese (BMI 440 kg m À2 ) Caucasian male individuals. Results: The excess obese individuals who underwent bariatric surgery as a weight loss strategy were studied before, 3 and 12 months after losing on average, 66.9 kg ( ± 95% CI 55.8, 77.9 kg; on average, 45% of their weight). The obese individuals who underwent diet modifications were studied before dieting and when resistance to weight loss occurred after losing on average 11.7 kg ( ± 95% CI 9.3, 14.2 kg; on average, 12% of their weight). The control group was studied twice, 50 weeks apart. In obese and excess obese individuals, losing weight reduced absolute knee muscular strength on average, by 8.2 kg (±95% CI 3.9, 12.5 kg; on average, 10% of their strength) and 23.9 kg ( ± 95% CI 12.1, 35.8 kg; on average, 33% of their strength). However, it also increased balance control measured with speed of the center of foot pressure, on average, by 0.10 cm s -1 ( ± 95% CI 0.05, 0.14 cm s -1 ; or increased of 12%) and 0.28 cm s -1 ( ± 95% CI 0.07, 0.47 cm s -1 ; increased of 27%), respectively. Relative strength increased approximately by 22% for only the excess obese group 12 months post surgery. Conclusion: This suggests, in overweight individuals, weight loss is more efficient at improving balance control than increasing, or even maintaining muscle strength. In these individuals, training programs aimed at improving balance control should primarily target weight loss.

Muscle Force and Force Control After Weight Loss in Obese and Morbidly Obese Men

Abstract: Despite a large force loss, particularly for the lower limbs in morbidly obese individuals after surgery, this loss is relatively well tolerated because the relation between force and body weight is even improved and the ability to maintain that force is preserved.
