Muscle power is a major neuromuscular factor affecting motor function and independence in patients with Parkinson's disease; and it is commonly targeted using high-speed exercise. This study examined the changes in velocities (Vpp) and percent loads (%1RMpp) at peak power, as well as load-velocity (L-V) and load-power (L-P) relationships, resulting from resistance training due to exercise choice and loading in older Parkinson's patients. Fourteen older adults with mild to moderate Parkinson's disease participated in a 12-week randomized controlled power training trial...

This study compared the post-activation potentiation (PAP) response of the hex bar deadlift (HBD) and back squat (BS) exercises. The PAP response between different levels of athletes was also compared. Ten professional and ten amateur rugby league players performed two experimental sessions. Participants performed a countermovement jump (CMJ) before and 2, 4, 6, 8, 10, 12, 14 and 16 minutes after a conditioning activity (CA) that contained 1 set of 3 repetitions at 93% 1RM of either HBD or BS. A force platform determined peak power output (PPO), force at PPO, velocity at PPO and jump height of each CMJ...

Sung Jin Yoon, Moon Jin Lee, Hyo Min Lee, Jin Seok Lee
BACKGROUND: Several recent studies have reported that heat stress stimulates the activation of heat shock protein 72 (HSP72), leading to an increase in muscle synthesis. Some studies suggested that low-intensity resistance training combined with heat stress could improve muscle size and strength. AIM: This study aimed to identify the effect of low-intensity resistance training with heat stress over 12 weeks on the HSP72, anabolic hormones, muscle size, and strength in elderly women...

Purpose: To determine if heavy resistance training in hypoxia (IHRT) is more effective at improving strength, power, and increasing lean mass than the same training in normoxia. Methods: A pair-matched, placebo-controlled study design included 20 resistance-trained participants assigned to IHRT (FIO2 0.143) or placebo (FIO2 0.20), (n = 10 per group). Participants were matched for strength and training. Both groups performed 20 sessions over 7 weeks either with IHRT or placebo. All participants were tested for 1RM, 20-m sprint, body composition, and countermovement jump pre-, mid-, and post-training and compared via magnitude-based inferences...

BACKGROUND: Resistance training (RT) has been utilised to target muscle dysfunction associated with Chronic Heart Failure (CHF). However, there is limited meta-analysis evidence to support its use as a standalone therapy. This meta-analysis examined the effects of RT on muscle strength (one repetition maximum, 1RM and Peak Torque), aerobic capacity (VO2peak and 6min walk distance) and quality of life (QoL) in patients with CHF. METHODS: We searched Medline, EMBASE, Cochrane and CINAHL for studies published up to July 2016, combining terms related to the population (eg, heart failure, CHF) with terms for the intervention (eg, resistance, strength training) and the outcomes (eg, QoL, VO2peak,strength, aerobic capacity)...

Results regarding the acute effects of plyometric and resistance training (PRT) on running economy (RE) are conflicting. Eight male collegiate distance runners (21 ± 1 years, 62.5 ± 7.8 ml/kg/min V[Combining Dot Above]O2 peak) completed V[Combining Dot Above]O2 peak and 1 repetition maximum (1RM) testing. Seven days later, subjects completed a 12 minute RE test at 60% and 80% V[Combining Dot Above]O2 peak, followed by a PRT protocol or a rested condition of equal duration (CON). The PRT protocol consisted of 3 sets of 5 repetitions at 85% 1RM for barbell squats, Romanian deadlifts, and barbell lunges; the same volume was utilized for resisted lateral lunges, box jumps, and depth jumps...

The primary aim of this study was to assess the accuracy in estimation of repetitions to failure (ERF) during resistance exercise. Further, this investigation examined whether the accuracy in ERF was affected by training status, sex, or exercise type. Eighty-one adults (males, n = 53 and females, n = 28) with broad range of resistance training experience participated in this study. Subjects performed up to 10 sets of 10 repetitions at 70% 1RM and 80% 1RM for the chest press and leg press respectively. At the completion of each set, subjects reported their ERF and then continued repetitions to failure to determine actual repetitions to failure (ARF)...

INTRODUCTION: The present study investigated whether well-tolerated light-load resistance exercise (LL-RE) affects skeletal muscle fractional synthetic rate (FSR) and anabolic intracellular signaling as a way to counteract age-related loss of muscle mass. METHODS: Untrained healthy men (age: +65 yrs) were subjected to 13 hours supine rest. After 21/2 hours of rest, unilateral LL-RE was conducted consisting of leg extensions (10 sets, 36 repetitions) at 16% 1RM. Subsequently, the subjects were randomized to oral intake of PULSE (4g whey protein/hour; N=10), BOLUS (28g whey protein at 0 hours and 12g whey protein at 7 hours post-exercise; N=10) or placebo (4g maltodextrin/hour; N=10)...

Clare F Heisey, J Derek Kingsley
Static stretching was once recognized as a method of preparation for physical activity that would inhibit performance and increase risk of injury. However, a growing body of research suggests that static stretching may not have an inhibitory effect. Regardless, the data have not examined gender differences or the fatigue index (FI) and flexibility effects of static stretching on the back squat over multiple sets. Therefore, the purpose of this study was to examine the relationship between a static-stretch condition (SC) and control condition (CC) on flexibility and the FI of Division I female athletes during 4 sets of the back squat...
