- Chronic Effects of Different Intensities of Interval Training on Hemodynamic, Autonomic and Cardiorespiratory Variables of Physically Active Elderly PeoplePublication . Sant’Ana, Leandro; Monteiro, Diogo; Budde, Henning; Ribeiro, Aline Aparecida de Souza; Vieira, João Guilherme; Monteiro, Estêvão Rios; Scartoni, Fabiana Rodrigues; Machado, Sergio; Vianna, Jeferson MacedoInterval training (IT) is a very efficient method. We aimed to verify the chronic effects of IT with different intensities on hemodynamic, autonomic and cardiorespiratory variables in the elderly. Twenty-four physically active elderly men participated in the study and were randomized into three groups: Training Group A (TGA, n = 8), Training Group B (TGB, n = 8) and control group (CG, n = 8). The TGA and TGB groups performed 32 sessions (48 h interval). TGA presented 4 min (55 to 60% of HRmax) and 1 min (70 to 75% of HRmax). The TGB training groups performed the same protocol, but performed 4 min at 45 to 50% HRmax and 1 min at 60 to 65% HRmax. Both training groups performed each set six times, totaling 30 min per session. Assessments were performed pre (baseline) after the 16th and 32nd intervention session. The CG performed only assessments. Hemodynamic, autonomic and cardiorespiratory (estimated VO2max) variables were evaluated. There were no significant differences between protocols and times (p > 0.05). However, the effect size and percentage delta indicated positive clinical outcomes, indicating favorable responses of IT. IT may be a strategy to improve hemodynamic, autonomic and cardiorespiratory behavior in healthy elderly people.
- Self-selected Recovery in High-intensity Interval Training Promotes Positive Responses in Affect, Pleasure, and Mood in Young PeoplePublication . Sant’Ana, Leandro; Vianna, Jeferson Macedo; Travassos, Bruno; Nakamura, Fábio Yuzo; Teixeira, Diogo; Scartoni, Fabiana Rodrigues; Dias, Amandio; Antunes, Raul; Rodrigues, Filipe; Matos, Rui; Machado, Sérgio; Monteiro, DiogoIntroduction: High-Intensity Interval Training (HIIT) with self-selected recovery can promote positive emotional responses. This study aimed to verify the acute responses to HIIT with fixed recovery and to select high scorers on the state of affect, enjoyment, and mood in healthy young people. Methods: Nineteen participants took part in the study (19.0±1.0 years, 64.0±9.2 kg, 169.1±8.5, and 22.0±2.0 BMI). They performed 10 x 30 s (95% V peak ) with 1 min recovery (HIIT RecA - active - 40% V peak ) and self-selected (HIIT Rec-B ). Affect, enjoyment, and mood were assessed before and after HIIT (both conditions). Results: In both conditions, for time 1 and 2 were positive in positive ( p =.170, EF: .102) and negative ( p =.0.90, EF: .151) affect, pleasure ( p =.010, EF: .315), and mood domains (tension: p <.001, EF: .673; depression: p =.015, EF: .286), anger: p =.033, EF: .230, and mental confusion: p <.001, EF: .451). In contrast, there was a reduction in the vigor domain and an increase in fatigue, with no differences in all emotional variables for condition and time*condition ( p >.05). Conclusion: Thus, selected self-recovery may be a strategy in prescribing HIIT with possibilities of not interfering with the emotional aspects, researched here.
