Sex Differences in Response to a 12-Week Resistance Training Exercise Intervention After Cardiac Surgery: A Proof-of-Concept Intervention Trial
Cardiopulmonary rehabilitation, which often follows major acute cardiac events, is traditionally focused on aerobic exercise and has been associated with decreased morbidity and mortality. Its benefit among cardiac surgery patients is less clear, as is the role of resistance-based exercise programs and their sex-specific effects. This study seeks to evaluate the safety and feasibility of a 12-week resistance training program in patients post cardiac surgery through a sex-specific lens.
We conducted a nonrandomized feasibility trial with a 12-week strength training exercise intervention. The primary outcome was safety and feasibility. Secondary outcomes included changes in strength, endurance, and functional capacity; and sex differences among these. Adult participants post open-heart surgery who had completed traditional cardiac rehabilitation were consented. Both patients who completed (cases) or did not complete (controls) a tailored 12-week resistance training program underwent comprehensive assessment of physiologic and physical fitness measures pre- and postintervention.
Nine participants enrolled in the trial, including 6 in the intervention arm (median age 61 years; 67% male) and 3 in the control arm (median age 66 years; 67% male). No serious adverse events were noted, indicating safety of the intervention. Participants completed a mean of 34.8/36 (96.7%) of sessions, indicating the feasibility of the program. Although not powered for statistical significance, patients experienced positive trends of improvement in measures of hand grip strength, endurance, and functional capacity with the intervention. When stratified, females experienced greater gains than males in these measures.
This proof-of-concept study found that resistance-based exercise after cardiac surgery is well tolerated and feasible. Although all patients experienced improvements in exercise parameters, females reported greater relative improvement than males.
•The role of resistance-based exercise programs after cardiac surgery is unclear.•Prior data suggest that women may benefit more than men from exercise.•In this feasibility trial, all participants in a structured strength training program experienced benefits in strength, endurance, and functional capacity.•Women experienced greater gains than men.

Resistance exercise and breast cancer–related lymphedema—a systematic review update and meta-analysis
Background
The purpose of this systematic review update and meta-analysis was to analyze resistance exercise (RE) intervention trials in breast cancer survivors (BCS) regarding their effect on breast cancer-related lymphedema (BCRL) status and upper and lower extremity strength.
Methods
Systematic literature search was conducted utilizing PubMed, MEDLINE, and Embase databases. Any exercise intervention studies—both randomized controlled and uncontrolled—which assessed the effects of RE on BCRL in BCS in at least one intervention group published between 1966 and 31st January 2020 were included. Included articles were analyzed regarding their level of evidence and their methodological quality using respective tools for randomized and nonrandomized trials of the Cochrane collaboration. Meta-analysis for bioimpedance spectroscopy (BIS) values as well as upper and lower extremity strength was conducted.
Results
Altogether, 29 studies were included in the systematic review. Results of six studies with altogether twelve RE intervention groups could be pooled for meta-analysis of the BCRL. A significant reduction of BCRL after RE was seen in BIS values (95% CI − 1.10 [− 2.19, − 0.01] L-Dex score). Furthermore, strength results of six studies could be pooled and meta-analysis showed significant improvements of muscular strength in the upper and lower extremities (95% CI 8.96 [3.42, 14.51] kg and 95% CI 23.42 [11.95, 34.88] kg, respectively).
Conclusion
RE does not have a systematic negative effect on BCRL and, on the contrary, potentially decreases it.

Metabolic Effects of Aerobic Training and Resistance Training in Type 2 Diabetic Subjects: A randomized controlled trial (the RAED2 study)
OBJECTIVE: To assess differences between the effects of aerobic and resistance training on HbA1c (primary outcome) and several metabolic risk factors in subjects with type 2 diabetes, and to identify predictors of exercise-induced metabolic improvement. RESEARCH DESIGN AND METHODS: Type 2 diabetic patients (n = 40) were randomly assigned to aerobic training or resistance training. Before and after 4 months of intervention, metabolic phenotypes (including HbA1c, glucose clamp–measured insulin sensitivity, and oral glucose tolerance test–assessed β-cell function), body composition by dual-energy X-ray absorptiometry, visceral (VAT) and subcutaneous (SAT) adipose tissue by magnetic resonance imaging, cardiorespiratory fitness, and muscular strength were measured. RESULTS: After training, increase in peak oxygen consumption (VO2peak) was greater in the aerobic group (time-by-group interaction P = 0.045), whereas increase in strength was greater in the resistance group (time-by-group interaction P < 0.0001). HbA1c was similarly reduced in both groups (–0.40% [95% CI –0.61 to –0.18] vs. –0.35% [–0.59 to –0.10], respectively). Total and truncal fat, VAT, and SAT were also similarly reduced in both groups, whereas insulin sensitivity and lean limb mass were similarly increased. β-Cell function showed no significant changes. In multivariate analyses, improvement in HbA1c after training was independently predicted by baseline HbA1c and by changes in VO2peak and truncal fat. CONCLUSIONS: Resistance training, similarly to aerobic training, improves metabolic features and insulin sensitivity and reduces abdominal fat in type 2 diabetic patients. Changes after training in VO2peak and truncal fat may be primary determinants of exercise-induced metabolic improvement.

Star wars : join the resistance
Mattis Banz knows that he's meant to be a hero of the galaxy like the legendary Luke Skywalker, and when General Leia Organa's Resistance recruits him to join its efforts against the evil First Order, he finally has a chance to fulfill his destiny. But the rest of his squadron doesn't seem very promising. Sure, there's the Zeltron girl Lorica, famous for her exploits foiling evil smugglers, but there's also the swamp boy named Dec, who seems to enjoy causing trouble; Dec's \"brother,\" a droid who thinks he's a pilot; Sari, whose imposing size contradicts her sweet nature; and Jo, the stuffy group leader with secrets. How is Mattis supposed to be the next Poe Dameron when he and his squad mates spend more time in trouble than flying X-wings? The team will have to learn how to work together when the going gets tough, or they won't be going anywhere.

Low-intensity resistance training with blood flow restriction improves vascular endothelial function and peripheral blood circulation in healthy elderly people
Purpose
The present study aimed to investigate the effects of low-intensity resistance training with blood flow restriction (BFR resistance training) on vascular endothelial function and peripheral blood circulation.
Methods
Forty healthy elderly volunteers aged 71 ± 4 years were divided into two training groups. Twenty subjects performed BFR resistance training (BFR group), and the remaining 20 performed ordinary resistance training without BFR. Resistance training was performed at 20 % of each estimated one-repetition maximum for 4 weeks. We measured lactate (Lac), norepinephrine (NE), vascular endothelial growth factor (VEGF) and growth hormone (GH) before and after the initial resistance training. The reactive hyperemia index (RHI), von Willebrand factor (vWF) and transcutaneous oxygen pressure in the foot (Foot-tcPO
2
) were assessed before and after the 4-week resistance training period.
Results
Lac, NE, VEGF and GH increased significantly from 8.2 ± 3.6 mg/dL, 619.5 ± 243.7 pg/mL, 43.3 ± 15.9 pg/mL and 0.9 ± 0.7 ng/mL to 49.2 ± 16.1 mg/dL, 960.2 ± 373.7 pg/mL, 61.6 ± 19.5 pg/mL and 3.1 ± 1.3 ng/mL, respectively, in the BFR group (each
P
< 0.01). RHI and Foot-tcPO

Improving spinal alignment through innovative resistance training with outdoor fitness equipment in middle-aged and older adults: a randomized controlled trial
The main objective of this study was to analyze the effect of a resistance training program using outdoor fitness equipment (OFE) on sagittal spine disposition and pelvic tilt in middle-aged and older adults. One hundred and twenty-eight middle-aged and older adults were randomly assigned to the training (TG) or control group (CG). The TG trained for 8 weeks, with 2 weekly sessions of one hour of resistance circuit training with OFE. Before and after the intervention, the sagittal spine disposition and pelvic tilt in the relaxed standing and sitting positions were analyzed. The results showed that the TG obtained a significant reduction (p < 0.001) in all the curvatures of the sagittal spine disposition and pelvic tilt in the standing position after the intervention, in contrast to the CG, which only showed a significant reduction in pelvic tilt (p = 0.005). Regarding the sitting position, only the TG presented a significant decrease in lumbar lordosis (p < 0.001). In conclusion, resistance training with OFE may be useful in improving sagittal spine disposition in middle-aged and older adults. Given the availability of free OFE in parks, the present research provides elders with an accessible and effective training program to curb the effects of ageing on the sagittal spine disposition.
