Background: Currently the resistance training (RT), is considered a contributor to improved mental health, however, is not reported in the literature an frequency ideal of training. Purpose: The purpose of this study was to assess the impact of the practice of RT on the psychological health of employees participating in a corporate wellness program, in different numbers of weekly sessions (2, 3 and 4 times), for a total of 12 weeks. Methods: 77 individuals were selected; 33 women and 44 men, between the ages of 30 and 45, employees participating in a corporate wellness program. The individuals were randomly divided and classified as control group (n=10) and three more groups (G2,G3, and G4), according to weekly training frequency. The groups followed RT programs made up of eight exercises with medium intensity of 10RM for 12 weeks. The General Health Questionnaire with 12 items (GHQ-12) was applied before and after the intervention period. The GHQ-12 results were calculated using the Likert scale format. Results: Significant statistical differences were noted between pre and post-intervention periods in all groups, indicating improvement in psychological health, most noted in G4. Conclusions: The data revealed that RT is capable of improving mental state in its practitioners after three months of training and that weekly frequency has little influence in this improvement, even though the group that trained with more frequency presented slightly higher levels of improvement in psychological wellbeing.

CrossFit® is a training program characterized by high intensity stimulus with constantly varied and multifunctional movements that induces a significant range of physiological, hemodynamic and biochemical responses. Heart rate variability (HRV) can be used to measure how individuals react to physiological stress and fatigue. Thus, the aim of this study was to verify HRV and blood pressure acute responses during and after three sessions of Crossfit®. Nine subjects with more than one year of experience performed three different sessions of CrossFit® to verify the response of systolic blood pressure (SBP), diastolic blood pressure (DBP) and HRV. Significant reductions in HRV were observed through parasympathetic indexes (High Frequency(HF), p<0.001) and an increase in the activity of sympathetic indexes (Low Frequency (LF), p < 0.01; LF/HF, p<0.001) after all Crossfit® workouts. SBP decreased ​​(p<0.05) and there were no significant differences between workouts of the day in both HRV and SBP. Different CrossFit® sessions induced similar activity of the autonomic nervous system with reduced HRV and post-exercise hypotension.

The aim of the present study was to verify the acute effect of remote and local IPC application before isometric strength, lumbar and lower limbs manual grip, and upper limbs and trunk muscle endurance tests in recreationally trained individuals. The volunteers were 22 men (age: 26.2 ± 6.9 years, weight: 83.4 ± 11.6 kg, height: 175.4 ± 5.8 cm, BMI: 27.1 ± 3.5 kg.m-2) recreationally trained (4.6 ± 3.3 years) in resistance exercise (RE) that performed three visits on non-consecutive days (three to seven days apart). This was a crossover and randomized study. In the first visit, the Informed Consent Form (ICF) was signed, according to the Declaration of Helsinki, and the PAR-Q was completed. Immediately after, anthropometrics was assessed, followed by familiarization with the tests. At the second and third visits, the volunteers were randomly assigning to the following experimental protocols: a) IPC protocol with 220 mmHg + isometric strength and muscular endurance tests (IPC); or b) control protocol (CON) isometric strength and muscular endurance tests. Isometric handgrip strength was significantly higher in IPC compared to CON (61.59±10.18 vs. 58.95±10.84, 4.47Δ%, p=0.01). Lumbar isometric strength was significantly higher in IPC compared to CON (165.36±22.56 vs. 156.77±22.81, 5.48Δ%, p= 0.01) and lower limbs isometric strength was significantly higher in IPC compared to CON (163.09±22.92 vs. 154.86±21.55, 5.31Δ%, p=0.01). Push-up repetitions were significantly higher in IPC compared to CON (43±12.80 vs. 38.91±13.03,10.51Δ%, p=0.01). The trunk flexion repetitions were significantly higher in the IPC compared to the CON (46.05±13.28 vs. 40.23±11.18, 14.46Δ%, p=0.01). In conclusion, local IPC significantly increased upper limb isometric strength and muscle endurance compared to the control protocol. Remotely, IPC significantly increased lower limb isometric strength, lumbar and trunk flexion muscular endurance compared to the control protocol.
