“…In addition, we did observe this potential moderation even when controlling for exercise-related variables such as duration, volume, intensity, and the prescription of aerobic exercise. As a result, those adults who present with limited mobility due to very high levels of fat mass (119)(120)(121) may derive substantial reductions in fat mass, even adopting a lower resistance exercise dosage prescription with caloric restriction, which may be a feasible strategy to improve adherence in this group.…”

Purpose: This study aimed to analyze whether the effects of resistance exercise on whole-body fat and lean mass are moderated by exercise dosage (i.e., duration, volume, and intensity), age, body mass index, baseline values, assessment methods, and prescription of aerobic exercise and caloric restriction in overweight/obese adults. Methods: A systematic search was undertaken in 11 databases from inception to December 2020, with an updated search undertaken in April 2022. Eligible randomized controlled trials examined the effects of resistance-based exercise programs on whole-body fat mass and lean mass in adults who were overweight or obese. Meta-analysis was undertaken with a random-effects model. Associations between mean differences and potential moderators were tested by meta-regression models. Results: Sixty-seven articles describing 65 trials (n = 2537) were included. Resistance-based exercise programs resulted in a significant change of −1.6 kg (95% confidence interval [CI] = −1.9 to −1.3 kg, P < 0.001) in whole-body fat mass and +0.8 kg (95% CI = 0.6 to 0.9 kg, P < 0.001) in lean mass. Male participants experienced greater effects than females (P < 0.001), whereas those presenting with higher levels of fat mass at baseline experienced greater reductions in this outcome (P = 0.084). For lean mass, younger adults experienced greater improvements compared with older participants (P = 0.009), whereas programs comprising resistance exercise and caloric restriction resulted in significant reductions in lean mass (P = 0.035). Resistance exercise dosage or prescription of aerobic exercise was not associated with change in these outcomes. Conclusions: Resistance-based programs improve body composition regardless of the resistance exercise dosage or aerobic component prescribed in adults who are overweight or obese. In addition, subgroups based on demographic characteristics, baseline levels, and presence of caloric restriction may present with more favorable responses in body composition.

“…External mechanical work decreased with speed for Omni walking while it increased for normal walking, with an increasing energy recovery for both gaits. As W EXT can also be considered as (1−Recovery)( W forward + W vertical ) (Luciano et al 2022 ), where ( W forward + W vertical ) is the sum of the increases in the kinetic energy of the forward motion and the vertical energy of BCoM, respectively, such opposite speed-dependency for W EXT is due to a divergent trend for this last term, rather than for the ability to behave in a pendulum-like manner. On the other hand, differences in W INT,k can be explained by differences in limb kinematics.…”

Purpose The purpose of this study was to investigate the metabolic cost (C), mechanical work, and kinematics of walking on a multidirectional treadmill designed for locomotion in virtual reality. Methods Ten participants (5 females, body mass 67.2 ± 8.1 kg, height 1.71 ± 0.07 m, age 23.6 ± 1.9 years, mean ± SD) walked on a Virtuix Omni multidirectional treadmill at four imposed stride frequencies: 0.70, 0.85, 1.00, and 1.15 Hz. A portable metabolic system measured oxygen uptake, enabling calculation of C and the metabolic equivalent of task (MET). Gait kinematics and external, internal, and total mechanical work (WTOT) were calculated by an optoelectronic system. Efficiency was calculated either as WTOT/C or by summing WTOT to the work against sliding frictions. Results were compared with normal walking, running, and skipping. Results C was higher for walking on the multidirectional treadmill than for normal walking, running, and skipping, and decreased with speed (best-fit equation: C = 20.2–27.5·speed + 15.8·speed2); the average MET was 4.6 ± 1.4. Mechanical work was higher at lower speeds, but similar to that of normal walking at higher speeds, with lower pendular energy recovery and efficiency; differences in efficiency were explained by the additional work against sliding frictions. At paired speeds, participants showed a more forward-leaned trunk and higher ankle dorsiflexion, stride frequency, and duty factor than normal walking. Conclusion Walking on a multidirectional treadmill requires a higher metabolic cost and different mechanical work and kinematics than normal walking. This raises questions on its use for gait rehabilitation but highlights its potential for high-intensity exercise and physical activity promotion.
