“…It should also be highlighted that the magnitude of changes to neuromuscular and soreness variables observed in this study are akin to those we have seen after competitive events such as a marathon (Clifford et al, 2017) or soccer match (Abbott, Brett, Cockburn, & Clifford, 2019). As such, the changes in muscle function and muscle soreness in the present study are likely a better reflection of the changes observed after more ecologically valid forms of exercise, than the changes observed after most lab-based exercise protocols that typically result in severe myofibrilar disruption, evoking symptoms that last for several weeks (Paulsen et al, 2012).…”

Purpose: This study examined whether a higher protein diet following strenuous exercise can alter markers of muscle damage and inflammation in older adults. Methods: Using a double-blind, independent group design, 10 males and eight females (age 57 ± 4 years; mass 72.3 ± 5.6 kg; height 1.7 ± 6.5 m) were supplied with a higher protein (2.50 g·kg−1·day−1) or moderate protein (1.25 g·kg−1·day−1) diet for 48 hr after 140 squats with 25% of their body mass. Maximal isometric voluntary contractions, muscle soreness, creatine kinase, Brief Assessment of Mood Adapted, and inflammatory markers were measured preexercise, and 24 hr and 48 hr postexercise. Results: The maximal isometric voluntary contractions decreased postexercise (p = .001, ), but did not differ between groups (p = .822, ). Muscle soreness peaked at 24 hr post in moderate protein (44 ± 30 mm) and 48 hr post in higher protein (70 ± 46 mm; p = .005; ); however, no group differences were found (p = .585; ). Monocytes and lymphocytes significantly decreased postexercise, and eosinophils increased 24 hr postexercise (p < 0.05), but neutrophils, creatine kinase, interleukin-6, C-reactive protein, monocyte chemotactic protein-1, and Brief Assessment of Mood Adapted were unchanged by exercise or the intervention (p > .05). Conclusion: In conclusion, 2.50 g·kg−1·day−1 of protein is not more effective than 1.25 g·kg−1·day−1 for attenuating indirect markers of muscle damage and inflammation following strenuous exercise in older adults.

“…While MPS can serve as a proxy for muscle reconditioning, it may not be an appropriate estimate of chronic muscular adaptation [25]. Importantly, recent investigations have reported pre-sleep whey [12] and casein [13] protein improves muscle recovery following exercise induced muscle damage and improvements in overnight net protein balance coincide with improved functional recovery [12]. As all pre-sleep protein supplement studies to date have used dairy-based protein sources, the present study was designed to compare the effects of whey protein and plant-based combination protein on muscle recovery in middle-aged men following damaging eccentric exercise.…”

“…In fact, a recent meta-analysis determined that protein supplementation had a small to moderate effect on muscle recovery [8]. Research in the past decade has indicated pre-sleep protein consumption as a viable method for increasing overnight MPS, lean mass accrual, and muscle recovery [9][10][11][12][13][14][15] without altering fat metabolism [16,17] or sleep quality [17][18][19].…”

“…These authors reported improved net protein balance and beneficial effects for protein on MVC (ES: 0.76), Wingate peak power (ES: 0.55), and repetitions to failure (ES: 0.44) 24 h post-exercise. Abbott et al provided a larger bolus of 40 g pre-sleep casein protein or CHO to trained soccer athletes following night-time soccer matches in a crossover design [13]. Pre-sleep casein protein resulted in a beneficial effect of protein for muscle soreness (large), countermovement jump (small to moderate), and reactive strength index (large) in the 60 h following exercise.…”

Effects of Pre-Sleep Whey vs. Plant-Based Protein Consumption on Muscle Recovery Following Damaging Morning Exercise

Pre-sleep whey protein intake has been shown to improve overnight muscle protein synthesis, muscle size and strength, and muscle recovery. Despite a growing interest in alternative protein sources, such as plant-based protein, there is no evidence regarding the efficacy of plant-based proteins consumed pre-sleep. Therefore, we aimed to compare whey vs. plant-based pre-sleep protein dietary supplementation on muscle recovery in middle-aged men. Twenty-seven recreationally active, middle-aged men performed 5 sets of 15 repetitions of maximal eccentric voluntary contractions (ECC) for the knee extensors (ext) and flexors (flex), respectively, in the morning. Participants consumed 40 g of either whey hydrolysate (WH, n = 9), whey isolate (WI, n = 6), rice and pea combination (RP, n = 6), or placebo (PL, n = 6) 30 min pre-sleep on the day of ECC and the following two nights. Catered meals (15% PRO, 55% CHO, 30% Fat) were provided to participants for 5 days to standardize nutrition. Plasma creatine kinase (CK), interleukin-6 (IL-6), and interleukin-10 (IL-10) were measured at pre, immediately post (+0), +4, +6, +24, +48, and +72 h post-ECC. Isometric (ISOM) and isokinetic (ISOK) maximal voluntary contraction force were measured at pre, immediately post (+0), +24, +48, and +72 h post-ECC. Muscle soreness, thigh circumference, and HOMA-IR were measured at pre, +24, +48, and +72 h post-ECC. CK was increased at +4 h post-ECC, remained elevated at all time points compared to baseline (p < 0.001), and was significantly greater at +72 h compared to all other time points (p < 0.001). IL-6 was increased at +6 h (p = 0.002) with no other time differing from baseline. ISOMext was reduced after ECC (p = 0.001) and remained reduced until returning to baseline at +72 h. ISOMflex, ISOKext, and ISOKflex were reduced after ECC and remained reduced at +72 h (p < 0.001). Muscle soreness increased post-ECC (p < 0.001) and did not return to baseline. Thigh circumference (p = 0.456) and HOMA-IR (p = 0.396) did not change post-ECC. There were no significant differences between groups for any outcome measure. These data suggest that middle-aged men consuming 1.08 ± 0.02 g/kg/day PRO did not recover from damaging eccentric exercise at +72 h and that pre-sleep protein ingestion, regardless of protein source, did not aid in muscle recovery when damaging eccentric exercise was performed in the morning.

“…Given the fact that no further nutritional intake occurs for several hours during sleep, pre-sleep casein protein intake has recently been recommended 5,6 . Casein protein accounts for a large portion of the total protein in milk and is characterized by its slow digestion and absorption 7 .…”
